The XMRV Buzz! - the CFS/ XMRV News Page
Sept 1st
- Filfa4 on the Forums pointed out there will be a webcast of the
final Q and A session that is billed to last 2 hours! The Q & A sessions are often
the most interesting parts of any conference; this one begins on 5:15 EDT on Wednesday,
Sept 08th.
Check out
the link here
Rrr on the Forums followed up with the NIH and learned that
all portions of the Workshop will be filmed and the
presentations will go up, subject to the presenters permission, on the NIH
website 2-3 weeks later so it's concievable we could have most of the Workshop
available for viewing. Thanks for Filfa4 and Rrr for being alert and getting us
this news.:)
August 31th
- It's a two day workshop. It starts out with basic
stuff; where the virus integrates itself into the cell's genome, which types of
mice may contain XMRV-like sequences, and then there is a presentation on a
'novel gene product' of XMRV - which means? what - a protein?? In any case it
appears to be something new to science which is always interesting.
In the next session there is a talk on animal
'models', which are animals researchers
use to give XMRV to and then study. Animal models are critically important to understanding how
pathogens function and its good to see researchers focusing on animal models so early.
Dr Bishop will
talk on 'Host Restriction Factors' which are factors in our cells that restrict
viral replication. These factors may be one reason why XMRV appears to be different in prostate cancer
tissues and the blood. Next comes a VERY INTERESTING lecture.
Dr. Villinger then talks on why
XMRV Induces a Chronic Replicative Infection in Rhesus Macque Tissues and
But Not in the Blood". We've been wondering where, if any place, XMRV is replicating? We know it
hardly happens in the blood but is there a tissue somewhere (besides the prostate) where it's
growing away? Dr. Villinger will tell us where in the bodies of these macaques XMRV has found
a home. Is it the nervous system? (Wouldn't THAT be exciting/appalling...) How
about the lymph nodes? The blood vessels? These are macaques, not humans, but
this presentation could have profound implications.
The next talk by Dr. Kazak will fit in perfectly here because he will look at different
variants in the XPRI receptor that XMRV uses to enter cells. These variants may determine which cells
XMRV can get into and cannot. The next day starts out with the prostate cancer series which we will bypass, except to say
that Dr. Singh is giving a lecture on pathogenesis. The section on CFS comes next.
Dr. Mikovits and Dr. Ruscetti chair the section and he (not Dr. Mikovits) will lead off with a talk on subject he was hardly aware of until two years ago - chronic fatigue syndrome. Dr. Hanson
is next. Thus far she has the only CFS/XMRV NIH grant that has been funded. It's
a full ROI grant which means (a) that she must have had some preliminary data
and (b) that data must have been positive - so here we appear
to have the
third positive XMRV study to appear. We
know she is studying Dr. Bell's pediatric patients (or formerly 'pediatric' now
middle-aged patients) and that her rather complex study wll look at a variety of immunological and other features. One interesting question will be if she has
blood samples from 25 years ago from these patients.
Right next to her
Dr. Huber will presumably report on her negative study - an
interesting juxtaposition indeed.
Dr. Lo will report on the Alter/Lo positive finding and then we believe we'll have
a second positive study report by none other than
Dr. Mikovits herself.
This appears to be the Invest in ME/WPI UK study that used an independent lab to
replicate the WPI's results. The title of this one is intriguing "the Detection
of Infectious XMRV in the blood of ....in the UK". One wonders if the inclusion
of the word "infectious' in there could mean anything special about this study?
The Assay development section will start off by a lecture by a man who's
never been able to find any XMRV in patient's blood -
Dr. Switzer of the CDC. After the Alter/Lo
study and the FDA's statement that 'sample preparation' could've played a role in the inability of
the CDC to find XMRV this lecture could be interesting. (Dr. Vernon's test tube comments come to mind)... Could
Dr. Switzer tell us
something surprising here? aka 'we made a mistake?'.
Dr. Bagni will represent the WPI as she
explains how to produce an antibody test for XMRV then we'll get good news about the development of
XMRV immunoassays for large scale population studies. Finally
Dr. Kearney
- who may be part of the Blood Working Group will talk on his success in finding XMRV in blood products.
(Things are definitely moving forward on the diagnostic front.)
In the last session on Epidemiology the
Bannert lecture will indicate to us that he did not find XMRV but he also shows that the bug can infect blood cells
- which sounds that he's replicated
a key part of the Science paper (!) but still can't find the virus...We'll have another opportunity for
another positive study when
Dr. Blomberg talks about his search for XMRV in Sweden. Finally it appears that another
member of the Blood Working Group will report multi-laboratory evaluations of different XMRV assays.
D
r. De Meirleir is believed to have a poster providing the results of another postive study
and the identification of an immmunological signature associated with XMRV infection. At this point
it appears there may be at least three positive studies and possibly four.
The 2-day Workshop indicates that
Science is marching forward very quickly; indeed at lightspeed compared to what we are used to. If XMRV wins out this could be just the beginning; the medical research establishment (contrary to our experience) in the US,
after all, is vast
indeed.
Months ago, Dr. Klimas reported that retrovirologists were hungry for something new...Might
ME/CFS go from doormat to hot research ticket? That would be something
indeed.
The Silence that Deafens
- how to explain what appears to be a near virtual media blackout on the Alter
study in the UK? Several UK residents have reported looking fruitlessly for any
mention of a paper that made it to several hundred other media outlets
elsewhere. Somehow the story didn't even make it onto the pages of the vaunted
BBC. (How does this story make it to Iran, of all places, and NOT the UK?) One
expects the Western media to display some independence but it seems that the
British media, at this point, is only interested in one kind of story on ME/CFS
and that story does not involve pathogens. Yes, they will cover a pathogen story
if they can't ignore it (and downplay it) but if they feel that they can ignore
it, then it appears that they will. It's amazing (and appalling) from the US
side to see an entire country's media en thrall to one belief system regarding
CFS and it definitely messes with one's idea of an informed and objective media.
What a rough ride UK patients have.....
As we watch the media in the US we can also see patterns forming. The Wall Street Journal has
a journalist who appears to be very interested in CFS and she has made a difference there. The NYT does its
generally thorough job and they've been giving XMRV and ME/CFS a real shot
throughout. The Chicago Tribune, on the other hand,
has focused on negative aspects. It appears that much matters on which journalist gets interested in the subject and what their
own particular slant is.
The message is- cultivate those reporters if you can.
NIH Goes Public on XMRV - The NIH finally threw its hat in the ring on the
new XMRV findings. In the NIH Research Matters section the official NIH release
starts off with a bang "New research supports the idea that viruses may play
a role in chronic fatigue syndrome (CFS), a debilitating disease that affects
millions of people nationwide" What a nice sentence that is; it fits in viruses,
a
debilitating disease and 'millions of people';
they almost make it sound like we have a major problem here....Did Fauci
groan when he saw this? Is he starting to wonder how he's going to explain how
under his direction the NIAID has basically ignored CFS and it's millions of
retroviral infected patients for decades? How he is going to explain his paltry
budgets over the past 25 years for the millions of ill patients? One fervently
hopes that at some point he'll be pressed at some point to explain just that. The neglect of the ME/CFS community
by the federal goverment borders on being criminal and hopefully the bureacrats in charge
will be held to account for their apathy and negligence. (Can you see a 60
minutes program lighting these people up? I can).
In any case the article illustrates that
no matter what happens with XMRV, CFS should now be associated in many people's
minds as something that's 'debilitating' and common. Overall its a nice little
article.
August 28th
Whoops! NIAID Steps Forward - It's true that the NIAID has been no friend to CFS...in fact none of the federal agencies could
be characterized as 'friends' and I really blasted them in the last buzz post but
that's all the more reason acknowledge them when they do shake off their
negative mindset and stepforward. I was informed that
it was none other than the NIAID that helped fund Dr. Alter's work. They definitely get two stars for that, and
hopefully, over time, we will see much more.
Dreambirdie's superb ME/CFS video is on CNN Ireport
- please check it out,
give it some hits and watch it spread.
Hot CFIDSLINK coming up.
The next weeks CFIDSLink is reportedly going to feature
Q&A's with professionals (including Dr. Alter) about XRMV. One question
we know Dr. Alter will be answering is if he found any MLV's in the CDC's
samples. If he didn't then either the CDC's 'CFS' group is not just different
but amazingly different from the Komaroff's group of CFS patients in the Alter study OR the
CDC has a problem with 'sample preparation'. It was Dr. Vernon who pointed out
that the CDC's test tubes might not have been right for virus collection. When a
virus is as rare as XMRV appears to be in the blood it might not take much to
knock out what little is there. What is going on? Maybe by Workshop we'll
know....
The September 7-8 International XMRV Workshop is going to be a doozy!
The
CDC will be presenting their lecture on assays just after Dr. Alter's assays
found MLV's....THAT will be interesting. Kate Bishop who basically cracked an
essential part of the XMRV mystery for Dr. Mikovits will be there. THAT is
encouraging. We believe that at least two positive XMRV studies will be reported
there and Dr. DeMeirleir will report that he's found distinct immune
abnormalities in XMRV infected patients. THAT will be outstanding. Other
researchers will, no doubt, be deep in discussion about MLV's and XMRV and how
to piece together all these different. THAT will be intriguing. Dr. Singh, from
what I've been told, from someone would know, may have the best XMRV studying
going and she's talking as well....and at the OFFER Conference on Sept 11th in
Salt Lake City. THAT will be illuminating.
This is the hot ticket in
town! The Workshop filled up quickly and is no longer open but congratulations
to those CFS patients who managed to get in (And boo-hoo for us (me!) who
didn't)....We look forward to your reports!
August 27th
Medscape News Praises Alter
Study - while being careful to cite issues that need to be cleared up
Medscape News turned in a very positive assessment not only of the Alter study
but the impact of the study on the field. We learned that the Alter group tested
some of the CDC's samples but that they weren't able to provide samples to the
CDC themselves because they didn't have enough material.
Dr. Alter suggested that the different retroviruses the WPI and his group picked up
may be due to geographic differences in prevalence and patient selection.
"Dr. Alter said the most likely reason for the discrepancy in results is patient selection. Diagnosis of CFS is based on a symptom complex, not a specific disease marker.
All patients in the NIH-FDA study met the accepted diagnostic criteria for the syndrome, and most blood samples
were from the patient population of a single coauthor, who is a CFS expert, he said.
"There may be a geographic difference," Dr. Alter told Medscape Medical News.
"In the Northeast, CFS may be due to MLV, and in the West, it may be due to XMRV."
which is an interesting idea but doesn't seem likely, at least from this
laymen's perspective, to hold.
It's true that the WPI patients came from
doctors across the country, none of which to my knowledge, was in the
Northeast. The WPI, however, has found XMRV variants in those patients dating back to the original paper. While those variants were not in the
original paper they were used as supporting material for the Science editors who
wanted confirmation that the WPI was not looking at a contaminant. The bottom
line is that the WPI has apparently known of XMRV variants from the beginning.
Canadians - Your XMRV study awaits you! - the CAA reported that Dr.
Eleanor Stein at the University of Alberta is starting an XMRV study for people
living in Calgary and Edmonton.
.
Science Article Charts Shift in Thinking - an article in the presitigous Science journal looked at the
Alter paper and found alot that it liked. Stating that "Even skeptics are impressed
by how much care the authors of the new study took to ensure accuracy" it was
clearly a very solid piece of work - even Dr. Monroe of the CDC agreed to that "The data do seem solid", admits Steve Monroe, director of CDC's Division of High-Consequence
Pathogens and Pathology." And he wasn't the only one "It's simply a good paper," adds virologist
Reinhard Kurth, former director of the Robert Koch Institute in Berlin.
Alter, a widely respected virologist and winner of the Albert Lasker Award for Clinical Medical Research,
"clearly knows what he is doing."
Questions lingered about reconciling the 'new' retroviruses found and the inability to find XMRV, and the disparate results of the other studies, and clearly more work needs to
be done to get the scientific community as a whole gets on board but one had the
feeling, barring some untoward surprise, that that was a matter of time. With regard to those 'new' retroviruses, Dr. Mikovits
reported that the WPI, over time, has found new variants. (In fact, Dr. Mikovits told me they are present in the WPI's patent
application.)
When will the research community get on board - one way or the other? We finally got
what appeared to be a solid date: "By
Christmas", Dr. Kurth reported - by Christmas they will have come to a consensus.
National Cancer Institutue (NCI) Producing XMRV 'Toolkit'
- BeesKnees on the
Forums reported that the the National Cancer Institute and Science Applications
International Corporation (SAIC) are creating an XMRV Toolkit to help study the
virus. We heard that the NCI had spent over a million dollars on basic XMRV
research and this may be the fruits of their labor. This toolkit, which consists
of 'expression plasmids' for all the proteins in XMR, will assist researchers in
many ways; developing antibody test, as a diagnostic tools, developing
vaccines and immunotherapy. It should accelerate research
greatly....."The development of these
XMRV tools is expected to save researchers months in laboratory
production time and thousands of dollars in labor costs."
The development of this tool demonstrates the leadership role the NCI
has played in XMRV. It also starkly illustrates how hands off the big retroviral institute at the NIH, the National Institute of Allergy and
Infectious Diseases (NIAID) has been. Patients and some researchers have been critical of the CDC's XMRV study but we should all
take note of the fact that if it was up to the NIAID, there might be no research at all
on XMRV. At least the CDC
has devoted some time and money to this issue. The NIAID backed away from ME/CFS
long ago and it continues to treat it as it would a pariah disorder. One might
ask who the bigger ogre is in this scenario.
FDA FAQ's on XMRV
- The FAQ's suggest that both the CDC and Dr. Alter are testing each others
samples. Dr. Alter did not find XMRV in the CDC samples either but what about
those MLV? And what had the CDC found in Dr. Alter's samples? All questions we
hope will be answered in that increasingly exciting Sept workshop.
Terrible Timing! CDC CFS Job Now Open!
- It took them, what? At least
six months, but the CDC has finally put the job posting for the CFS job out but
the timing or this is terrible and it suggests that either they've decided about
the role XMRV plays in CFS or they just don't care. With scientific consensus on
this all important pathogen just a few months away why not wait and be sure to
attract the right kind of individual for the job? The posting opened Aug 19th
and closes two weeks after that.

Four Viruses? The Alter Paper Arrives: A Review - I just posted a long review of this
complex and fascinating paper, and what, so far as I can figure out, it means.

DeMeirleir Reports RedLabs and Researchers Confirm WPI Findings - Dr.
DeMeirleir reported XMRV was alive and well in European ME/CFS patients. Unless
they are using a different technology than that licensed to them by VIP Dx this
was welcome but not startling news, as few expected the virus not to be found in
Europle. The most intriguing part of Dr. DeMeirleir's accouncement was that he
had identified an immune signature similar to that found in 'symptomatic' HIV
patients. There was no telling why that signature had not popped out before in
ME/CFS but it could be that it is showing up now because of the more
selective cohort (ie XMRV positive patients). Dr. De Meirleir sounded very
hopefull stating "It seems that for the roughly 17 million CFS / ME patients
world-wide end to a long ordeal surrounding the recognition of their illness.
The development of targeted therapies is already underway, both in Belgium and
abroad" He will report his finding at the Sept 7/8 workshop.

- Kitei Paper on Alter Story - doing her due diligence Mindy Kitei at CFS
Central not only got a hold of the paper before publication but also interview
Dr. Alter, Dr. Komaroff and others. (You
can now find the paper here.
Check out a commentary on the findings here)
The surprise of the paper was what Dr. Alter didn't find - "XMRV"! Even more surprising was the fact that
his finding of a melange of closely related viruses actually made sense in some ways. One reason that none of the six or so
CFS studies have been able to find 'XMRV' may be that the type of XMRV they looked for was different.
As Dr. Mikovits reported in
"A Different Kind of XMRV" the reference type for XMRV testing was
derived, naturally, from the sample they had on hand which were from prostate
cancer patients. Several studies since the publication of the Science paper have
indicated, however, that the makeup of XMRV in prostate cancer tissues
very likely differs from that found in the blood cells. That appeared to be due
to the APOBEC3 enzyme present in blood cells which swapped out amino acids in
the RNA of the virus.
Dr. Mikovits talks about this is a
video posted shortly after the finding,
where she states that it appears that 'a family of murine retroviruses appear to
have infected people with ME/CFS.
It's still a mystery, at least to me, however, how the WPI
found XMRV at all since they presumably started searching for it in the blood last year using
the material they had on hand -which were reference samples from the prostate. It may be
that faulty methodology indeed, still does play a role in the inability of other
groups to find this virus.
Kitei rKitei reported
that Dr. Alter believes his
findings confirm the original XMRV findings stating "Viruses tend not to be homogenous,” Alter explained to CFS Central
in a telephone interview. “The fact that we didn’t find XMRV doesn’t bother me because we already knew that retroviruses
tend to be variable. They mutate a lot, basically. This is true of HIV and HCV [hepatitis C virus]. It’s not one virus. It’s a family of viruses.”
Dr. Alter should certainly know - his work on hepatitis viruses that lead to the discovery of two new
viruses garnered him the 'Nobel Prize' of Medicine - the Lasker Award.
Dr. Alter found no less than four different types of heretofore undiscovered mLV's in CFS. They were named, appropriately,
"CFS Type I", "CFS Type II", etc.
Mutating over time like any good virus should - Dr. Alter was also able to find the pathogens in blood that was fifteen years old
and then retest those individuals today. He found the virus present in 7/8 of them in mutated form - which is exactly what one would
expect from a virus over tiem.
According to Kitei, Dr. Alter felt the delay in releasing the study
only strengthened the study, stating “There were no changes in the conclusions,
but we added data that made the conclusions stronger,” he explained. “For one
thing, we did some further work to feel confidant that there was no
contamination…. We had hundreds of negative controls, and every assay had
negative controls. And then we used an assay from mouse mitochondrial DNA and
found that there was no evidence of mouse contamination. We had variation in the
viruses we were finding. If there was a contaminant, you’d find one species, not
several.”
Now Dr. Alter will give XMRV its next big test - he will search for it in a wide variety of
disorders. The danger is that it is widespread in chronic diseases, which, would negate its importance
unless it really is some sort of superbug. Hopefully, it will be found clustered in a series of
'NEID's' such as FM, GWS, MCS, IBS. Now we await the results of the briefing.

- VIP Dx Announces New Tests - In a nice bit of timing
VIP Dx announced a new antibody test for
XMRV and its related variants. The related variants item - the fact that
more types of human murine related retroviruses are present in ME/CFS- is the
second bit of big news we expect the Alter paper to bring. This finding - that a
variety of heretofore undetected 'mouse' retroviruses, all closely related to
XMRV have infected the human population could, one would imagine, unleash an
enormous amount of interest in the scientific community and possibly pave the
way for insights into a number of different diseases and/or explain the
different subsets in CFS. (If 80% of CFS patients test positive for XMRV then
something will need to explain the subsets within that
subset). The case with HIV is possibly quite instructive as different
types of HIV result in dramatically difference illness courses with the
mortality rate for one form significantly lower than the other.

August 22nd
- Alter Buzz - the Buzz around town is that the Alter paper is coming
out this week and that it will completely confirm the WPI's findings and
go further. That, in fact, is what we would expect
- each paper should build on the other ones and go further. If the Buzz is
correct the blockbuster paper will come out on Tues. Only time will tell; if it
is don't be surprised if you
see articles in the media appearing the same day. (In fact they may come out
first if you're up early enough).
- Opening the Door to a New Era: the WPI Arrives
- check out an article I wrote looking
at what Annette and Harvey Whittemore have accomplished and celebrating the opening of the WPI.
- Best
State of the Art Facility' - That was how Dr. Barsky described the 77
million dollar Center for Molecular Medicine which the WPI is housed (along with two other programs). The Whittemore's kicked in a cool $5 million
dollars of their own money to get the facility built. There's quite a bit on the WPI on this nice overview
of the new building. Check it out here.
- XMRV in Press -- papers
on XMRV continue to pour out. The latest, a 50 plus page tome, described
successful efforts to detect antibodies in XMRV infected primates. Interestingly
they reported XMRV illicits a 'much less robust' antibody than HIV. Initial
antibody levels are high and then decline quickly to basal levels (?) after
about 4 months. They believe this is probably due to reduced replication levels
as the body gets the infection under control although they did note another
study indicated the virus was present in many organs (even if it's not
replicating). A similar antibody response occurs in HTLV infected primates
and it may not reflect what happens in humans.

HGRV Debuts
- A name change already? Now that is something people with
ME/CFS/CFIDS/ME/CFS/EBV Syndrome are familiar with. Things are moving fast at
the WPI. Feeling confident that issues about the XMRV's existence have been
settled they are building a foundation for the future, part of which involves calling this
pathogen by an appropriate name. As Dr. Burrascano pointed out XMRV is a human
not a mouse (ditch the M), you can't say its an exogenous virus because
it's a uniquely human virus (scratch the x); what it is is a human infectious gamma
retrovirus - the first one we know of; ie its an
HGRV.....the pronunciation of which is up to you. (These are biologists not poets). From an aesthetic standpoint it only
gets worse...the disorders associated with HGRV are HGRADS (Human gamma retrovirus associated disease).
So, congratulations - if you tested postive for XMRV you may have an HGRAD.
The tongue twisting names are not, unsurprisingly, going over well at the Forums. One person suggested it sounded like a
rocket launcher from the Soviet Union.
Some Forum members
have jumped in with their proposals. Human Associated Gamma Retrovirus Disease or HAGRID gets the
Harry Pottery character into the picture while being more picturesqe - I feel Hagrid - (haggard), HGIV, HGRV,
HGR........
That the new names will be proposed
in a just a few weeks at the XMRV Workshop on Sept 7th - demonstrates again how
confident the group is and suggests they may believe enough positive information
will be coming out over the next couple of weeks to sway the group. What a turnaround this is from a couple
of weeks ago when the CDC, having locked up the Assay presentation at the workshop, appeared to be in drivers seat with XMRV.
Hold onto your seats, Dr. Burrascano, a member of the Symposium stated "the volume of new and important information about this virus and its disease associations is increasing rapidly".
-
The Lo-CFS Connection - Dr. Alter appeared out of the blue; a major
researcher without any apparent connections to ME/CFS he appears to have stepped
in at just the right time to, kind of, save the day. But is he really out of the
blue? A thread on the Phoenix Rising Forums indicates that his partner,
Dr. Lo, played a major role in mycoplasma research and actually authored a paper
on CFS and mycoplasma. His record suggests that he's very good at finding
difficult to find bugs. He did not find an association between mycoplasma's and
CFS but it may be that he thought at some point a bug was going to show up.
August 15th
- Dr. Mikovits
Breaks the News on the FDA Paper
-Several weeks prior to publication Dr. Mikovits spilled the beans on the
FDA XMRV paper,
stating in an interview with RGJ.Com, what has seemed to
be more and more obvious - that the Alter paper is going to confirm the WPI's
findings when it is released. While no one yet had directly said so, the news
seemed to be in the air. In an interview in Nevada Newsmaker Annette Whittemore
very confidently said several new replication studies will shortly out confirm
the WPI's findings and the mood overall seemed very good.
It's a big day, a huge day for CFS and, of
course the WPI. How fitting that the WPI, which has endured six months of
skepticismas study after study has
failed to find XMRV not only in ME/CFS but in other diseases, was greeted with
this news as they cut the ribbons on their new facility. While much work remains
to be done the news that the several positive studies are on the way potentially
means a new dawn for ME/CFS. The
implications of the finding are truly immense - legitimacy, vastly increased
funding, new treatment possibilities and an immense, immense weight taken off
ME/CFS patients shoulders.
There was already good news on the treatment front from Andrea Whittemore, who
had became dangerously ill after having to go off Ampligen, as
she
reported on Nevada Newsmakers that she had improved significantly on new
treatments linked to XMRV. With the confirmation of XMRV in CFS the drug
companies appear to be picking up track right where they left off six months ago
when the negative studies appeared. Dr. Lombardi stated that treatment trials
could begin at the WPI soon.
Representatives of drug companies and diagnostic laboratories are reportedly
among those attending the WPI's Symposium this week.
Annette reported that the the WPI is
putting together a team of physicians to lead the medical end of the WPI as fast
they can and hope to open in medical side of the facility in late Fall.
Dr. Mikovits also scooped herself on a paper she expected to published at the
end of this year that she reported will demonstrate distinct immune
abnormalities are present in ME/CFS patients infected with XMRV. This is a major
accomplishment because it suggests an XMRV infection could have profound effects
on the immune system indicating it is more than a 'passenger virus'. With
researchers able to show XMRV is causing distinct immune abnormalities the next
step is to show that drugs that remove the virus and recorrect the immune system
abnormalities lead to improved health. Three drugs have been able to stop XMRV
in the lab and Dr. Lombardi felt many more were potential candidates stating
there was alot of 'low-hanging fruit' available on drug company shelves.

The ME/CFS Family Prevalence Poll
-how does a Family Prevalence poll show up on the XMRV buzz page? Because
if XMRV is infectious one would think that CFS or something like it would show up in families. The research
thus far hasn't really indicated a strong family connection but we thought we'd
do a poll of our own. Thus far our little unscientific poll suggests that ME/CFS
does show up quite frequently in the families of some PR Forum members. Of the 50 or so people that have taken the poll 40% have a close family member who's been
diagnosed with ME/CFS and an additional 25% have a relative. Another 16% have a relative who has a mysterious
fatiguing condition. Only 25% did not have a relative with either ME/CFS or a mysterious fatiguing condition - a very
different finding from the few studies that have been done. Check it out and
vote here (you must be registered in the Forums to vote)
- Breakthroughs Happen: A Model for ME/CFS Success
- while we're off-topic a bit I would like to promote a new article I did regarding the
big Alzheimer's Breakthrough that I believe has repercussion for ME/CFS. XMRV or not
- these teams illustrated the way to go in ME/CFS. The nice thing is that
something like it may be appears to be getting underway......Check out the article here.
- The Alter Paper Out Next Week? - Someone who may know reported
they believe it will be out next week; that would be on Tuesday.

UK Moves Ahead of US on Protecting the Blood Supply! - who would have ever
thought that the land of CBT and GET would race ahead of the US in their efforts
to protect the blood supply from CFS patients? According to a note received by
'Dancing with the Sandman' the UK will shortly exclude CFS patients as blood
donors because they have a relapsing/remitting condition (which could signify a
pathogen is present). Are more changes in store for the UK?

Dr. 'Rac' (can we call him Dr 'Rac' now?) on the Dutch XMRV HIV study
- Dr. Racaniello came down on the recent Dutch
study that found no XMRV in HIV patients semen. What was his call? Thumbs up or thumbs down? A decided thumbs down with our
viral reviewer finding that the study (remarkably enough) provided "little information on possible transmission mechanisms of XMRV."
How does a study on semen provide 'little information' on XMRV transmission? By centrifuging the samples thus
removing some of the potentially virus bearing cells from it. By not looking for 'proviral DNA' which is DNA that
has become integrated into the cells genome- which is, of course, what XMRV does as quickly as possible. By not checking if the
people with HIV were infected with XMRV in the first place.
The really interesting thing about Dr. Racaniello's
last suggestion is that he
asserts they should have cultured blood samples using LnCaP cells - the precise method the WPI has been calling
for for over half a year but which no one has done yet. He's clearly a believer in this technique and noted that
while its unusual, he didn't 'see any value' in doing it in any other way.

August 10th
- Alter Paper in Press - a couple of
days ago I reported that the Alter paper was at the pubulishers. Mindy Kitei at CFS Central has confirmed with the staff of PNAS that the
paper is 'in press' which appears to mean that its been accepted and will be
published in a future edition. They would not confirm a publication date but
PNAS is published weekly. Given the hot topic one would think publication is
imminent.
- Vice President of WPI Mike Hillerby Talks
- Mike Hillerby spent almost an hour
on KUNR talking about the WPI, XMRV and CFS. It turns out that the WPI has
several good spokesman as Mike turned in an engaging and articulate performance.
(He even has a good radio voice :)). They went through the history, talked a bit
about the difficulties of Dr. Peterson's early years and the orastracism he
faced in Incline Village. He noted that CFS was not a psychological disorder but
then asked who wouldn't get depressed at some course if you had a unremitting
illness with no cause, no treatment, little recognition and little research?
At one point he and Dan Erwine discussed how the psychological
interpretation of the disease had reduced funding for it - something that I
disagree with. Psychological disorders get enormous amounts of funding; if CFS
was an identified psychological disorder the disease would move into the National
Institutes Of Mental Health where it would surely receive a lot of funding.
The funding problem, in my opinion, is that CFS is viewed as a 'nothing', a
wastebasket disorder that is impossible to study. The CFS patients don't trust
the definition and neither does the research community - they don't think
there's any cheese down the CFS tunnel.
XMRV Prevalence - XMRV prevalence rates in CFS have held strong at the
WPI over time and perhaps have even increased. Mike stated that 80% of well identified
CFS patients have tested positive for XMRV. This is considerably higher than the
66% postive rate (if I remember correctly) reported by Dr. Lombardi at VIP Dx
some months ago and could reflect either a different patient cohort at the WPI
or improved recent testing measures. He also stated, as we've heard before, that XMRV
is being found in other neuro-immune diseases
Phone-ins -
In one of the early phone calls a woman who had CFS in high school and had been unable
to attend classes for three months reported that after going to Johns Hopkins and following their
protocol of a strict schedule and wake up times, an hour of exercise daily and salt tablets
that, although it was extremely painful, she recovered completely and had been recovered
ever since then. Her story just goes to show how diverse the CFS population is. Many people
with CFS, after all, have gone to John Hopkins, tried their protocols yet this is
the first positive story that I've heard.
Scientific Symposium? - apparently the WPI will shortly be
holding a Scientific Symposium on XMRV that will include researchers and
physicians from around the US. It's apparently an invitation-only event as
there's no mention of it in the Events section of the WPI's website. Reports are
its being held from 2-4 pm on the 16th.
Clinic Opening - the building the Institute is part of is going
to open on the 21st and the research staff will presumably move in but its going to take some time for the Clinic to open.
The Medical Director's position is still open, other staff still need to be hired and Mike
felt the clinic would probably not open before Fall or the end of the year. It should be
exciting when it does - Mike related how Dr. Peterson and Annette Whittemore got together several years ago
to create a place where they could send findings from the bedside right to the research lab and then back to the bedsidel.
They envisioned a
place where researchers and physicians were in close communication (ie
translational research). It'll be fascinating to see who is picked to fill Dr. Peterson's considerable shoes.
The Failed Validation Studies - when it came to talking about the failed XMRV studies,
Michael was very diplomatic saying simply that they had used different methods, that the
types of patients may have been different, that XMRV may have genetic variations in different groups of patients
and that the WPI was continuing to reach out to researchers around the world to
explain the techniques and provide them with
validated positive samples.
The Future and the Past - what does he see in the future? Alot of complicated work determining
who has XMRV, where in the body it's found, what it's viral loads are, how it might be
treated, etc. He also sees greatly accelerated progress (a 'bright light at the end of the tunnel'),
in both XMRV and CFS itself. If XMRV is validated he expects researchers from major institutions
across the US and the world to jump on board. The last year and a half must've been a whirlwind for
the WPI: "I don't think any of us" he said, referring to the creators of the WPI "would have thought we would have come as far as we have
in this short time"...Neither they nor us - that's for sure. It's been a remarkable ride,
indeed, for an Institute
that is finally going to really open its doors in the next couple of weeks.

Dr. Singh Talks! - Dr. Singh at the University of Utah is involved in one of the most comprehensive XMRV studies
in process. Dr. Racaniello had a nice long interview with her about XMRV, prostate cancer and CFS. The CFS portion of the interview starts
22 minutes into the interview. Of course we didn't hear anything about the results
of the study but we got a lot closer look at it and several other interesting
projects she has on XMRV. A blog on it will appear tomorrow and
you can check out
a discussion here.

A Big Thank You From People with ME/CFS to the WPI - the WPI's
grand opening is in a couple of days and Rrrr, who organized the flowers for Dr.
Peterson, did it again for Dr. Mikovits, Annette Whittemore and the staff of the WPI. The response was
so strong from the Phoenix Rising Forums and elsewhere that she had to stop asking people to donate. Three bouquets of long
stemmed roses from ME/CFS patients will greet Dr. Mikovits, Annette
Whittemore and the staff as they open the new facility.
- How to Say Almost Nothing at All - Mindy
Kitei's and Mary Schweitzer's Interview with Dr. Stephen Monroe of the CFS
- we saw a bureaucrat in full steam in Mindy Kitei's interview with Dr. Monroe.
No question was too piercing that it couldn't be turned into an opportunity to
state almost nothing. To the question
"Does the CDC care that patients have lost
confidence in the agency?", Monroe stated the "CDC is
deeply committed to reducing the morbidity and
societal costs associated with CFS to enable a better quality of life for CFS
patients." One wonders if his nose started to grow a bit when he let go
with that one. A
miniscule and ever reducing budget for a million plus person disorder, somehow, does not suggest that
the CDC is deeply committed to anything regarding chronic fatigue syndrome.
Dr. Monroe didn't even attempt to answer a question
regarding what the CDC is doing to help the large percentage of CFS patients
who do not receive significant benefits from CBT. Mindy and Mary then came up with a real
shocker; apparently the CDC was planning to spend the money determining if
foster care children were more likely to come down with CFS than non-foster care
children. I hadn't heard that but apparently it was on the books. Dr. Monroe
said that study has been canceled; one wonders, though, if anything more
exemplifies more the rut the CDC has found itself in.
Dr. Monroe let loose a real hooter when he suggested that the criteria for CFS
did not change when the Empirical definition was created. He stated "The CDC uses
quantitative assessment tools (eg Empirical Definition) to reproducibly identify those individuals who meet the 1994 international research case definition of CFS.
The defining symptoms and criteria for exclusion have not changed." This was despite
the CDC's (and other) studies finding that the definition did bring in a new group of patients and excluded
some people who had formerly met it. In their last question Mindy and Mary nailed the CDC on
inaccuracies in the XMRV paper concerning the Canadian Criteria and the Fukuda
criteria and again were met with a nonanswer.
One wonders why
Dr. Monroe and the CDC went to the trouble? If it was to suggest that they were
at least somewhat responsive to the patient community it failed miserably. If
you're not going to even attempt to met the questioner on their own ground why
do it? You either end up looking out of touch or uncaring - which is what
happened. For me, the interview simply demonstrated why people with CFS place so little
faith in the biggest CFS research program going. Better, really - for the CDC - that it had
never taken place. Check it out here.
August 7th
- The Mikovits-Ruscetti Paper- the two researchers have released an overview of what we know about
XMRV in a journal called Future Medicine. They note that a wide array of neurological, autonomic
and immune abnormalities are found in both CFS and AIDS; suggesting, of course, that retroviruses
tend to produce a lot of strange abnormalities. The fact that so many different things can go wrong in CFS
(but usually only in some this groups of CFS patients) has driven the research world crazy. Basically when they see a pattern like that
they think its all nonsense but Dr. Mikovits and Dr. Ruscetti suggest that this is what you might expect
from a retrovirus.
It was very nice to see them using myalgic encephalomyelitis/ chronic fatigue syndrome or ME/CFS
(as well as CFS) throughout the article - something we we rarely see; they are definitely on the cutting edge there.
August 6th
- THE Key Virus? - Reports are that the WPI has tested hundreds
of viruses and found that none of them, not HHV6, EBV, CMV or the others, is
associated with more than 10% of CFS patients. Only one virus - XMRV, has thus
far, has been found by the WPI in the majority of patients. This, of course,
suggests that if their finding is right then XMRV is the key player and that it
contributes to different opportunistic infections in different people (like that
other famous retrovirus, HIV). Annette Whittemore, by the way, is reportedly
very confident that the next slew of studies will start to validate the WPI's
findings.
- Ampligen and XMRV
- In a recent report Hemispherx stated that, in collaboration with the WPI, they are analyzing the samples gathered
during their Phase 3 trials for the FDA. We've heard reports that Ampligen was more helpful
in patients with documented XMRV infections than without them but we'll apparently (or rather hopefully) we'll
know for sure
in the next month as Hemispherx will be presenting its results at the International XMRV Workshop in early
September. A positive report won't resolve any of the basic questions about XMRV but it
could be helpful. Ampligen is, after all an immunomodulator with antiviral
properties; if Ampligen is more successful in XMRV positive patients than XMRV
negative patients this could lend some background credence to the idea that XMRV
is causing problems in CFS patients. Hemispherx, of course, does not have the
best reputation amongst researchers or investors - the research world probably
will not really taken note until they have hard, publishable evidence from them.

Dr Oz in La La Land on ME/CFS - Did a flying house hit him in the head? Did
he forget to click his heels twice? Whatever his problem according to reports on
the Phoenix Rising Forums Dr. Oz appears to be in la-la land with CFS - stating
in response to a question from George Stephanopoulos on Good Morning America
that green tea with D-Ribose is "one
of the things that I think is the easiest solution for a lot of folks who have
CFS....". No word on XMRV in the program but its hard to believe CFS
would've shown up on Good Morning America without it - so I snuck it in here.

NIH's ProjectReporter site. One is on cancer and gammaretroviruses, the other is

XMRV Not Found in Mysterious Flu-like Illnesses in Children in France -
Nobody but the WPI has yet been able to find XMRV in the blood and this study
was no exception. This study looked for XMRV in 'idiopathic' infectious
illnesses in children; ie children with flu-likenesses but no identifiable
pathogen - an interesting cohort indeed. They found no trace of XMRV but George
on the Phoenix Rising Forums noted a number of problems with the study; they
looked for a sequence (env) Dr. Ruscetti says is problematic, there were no
controls and they didn't attempt to spike a sample with XMRV to ensure that they
were able to find it.
- Alter Paper in Press? - Reports have it that the backup studies
on the Alter paper
have been completed and that the completed paper is at the Journal and that Dr.
Alter and his associated researchers feel certain it will be published (and
perhaps soon?).

Patenting XMRV - The race for the potentially lucrative XMRV patents is on. Thus far three patents have been registered,
all by co-authors of the Science paper; Dr. Mikovits et al. has one for measuring XMRV in the serum, Dr. Silverman has one
measuring it in the tissues and now in urine and prostate secretions.
- Patient Antiretroviral Treatment Trial Reports
Daffodil on the Phoenix Rising forums reportssome progress
after four months on anti-retrovirals but that she is still very sick and is having
problems with depression.
Jimbob on the Forums improved a good bit - he was still not nearly healthy -
but he reported good improvement during the 5 weeks he was on Raltegavir but
then fell apart and had to stop the drug. He was getting it free; he noted that
the normal cost per year was $14,000 (!).
Dr. Deckoff-Jones Reports
- Dr. Deckoff-Jones has been in touch with a group of people trying
antiretrovirals. She reports that of the 20 people that she knows that have tried the
drugs about a third have shown some improvement, a third haven't responded to them
(yet?) and about a third couldn't tolerate them. She suggests that many of the
people trying antiretrovirals right now - mostly older patients who have been
quite ill for a long time - are probably not the kind of people that will
respond optimally to them. For herself and her daughter their gains over the
past four to half months are holding and perhaps slowly increasing. She reports
that her feelings of flulike malaise are completely gone. Energy is better but
still a significant problem.
She notes that AIDS patients generally progress rapidly on antiretrovirals. So what is going on
with CFS patients? She notes
that AIDS patients are generally given antiretrovirals when their T. helper cells
start declining rapidly or when their viral loads get too high. She believes, if
I understood her right, that CFS patients are being given drugs long after
they've become ill. (Remember that people can carry HIV for long periods of time
before they become ill). It may be
that
the neurodegeneration/inflammation and even autoimmunity established in the body
after long
periods of XMRV infection in some CFS patients means they would be expected to improve very slowly
- and perhaps not as fully - as AIDS patients.
In her early blogs Dr. Deckoff-Jones asked why not give antiretrovirals a shot if
you're seriously ill? Now, talking to another subset of patients, she suggests that if you are in a 'successful holding
pattern' that you 'tread lightly' and 'not rock the boat' until we learn more.
After her terrible experience with anti-Lyme treatments (see her blogs) she's
plainly wary about some of the treatments doctors prescribe saying that 'sometimes less is more'. There's much more
to read in
her insightful blog.
No Miracle Drugs Yet - Anti-retrovirals have not been the miracle drugs once hoped
for. Should we have expected them to be? XMRV is not HIV - it does not appear,
at least in the blood, to be replicating rapidly - and these
antiviral drugs work by turning down the replication rate. (Is it replicating
rapidly somewhere else in the body? We just don't know.) Even if retrovirals
stop XMRV replication in the lab there is no data on how effective they are at
stopping XMRV replication in humans.
Besides what if replication has little to do with XMRV's effects?
What if the simple presence of XMRV in a cell is causing the immune system to overreact?
These drugs would be of little help then. Nor do we know what the right
combination of drugs will be. Will anti-herpes virus drugs be necessary for
some? How about immune modulators like Ampligen? (Hemispherx believes Ampligen
will aid anti-retroviral treatment). Finding an optimum combination of drugs
will likely take, just as it did with AIDS, years to figure out. While there is
certainly a logic to taking
anti-retrovirals, at this stage of the game, taking them has always been a crap
shoot. Its a learning experience for everybody. No one should think
doctors would get this right right off the bat.
-
IACFS/ME Makes A Statement - the IACFS/ME, the organization of CFS
professionals, has been mostly silent on XMRV. Now they have stirred themselves
to make a statement on the Alter paper imbroglio - a month or so after it
happened. Still, they provide an acute critique of the situation. If the purpose
of the "strategic pause" as Dr. Monroe called it was to clear up conflicting
results, then why release the CDC paper while the Alter group was still doing
more testing? Fred Friedberg, the President of the IACFS/ME, asserts that if the feds were going to go to the
trouble they did to hold back the papers then both papers should have been released at
the same time and then a forum should have been established for the authors to hash out their
differences.
The Alter paper was reportedly due out in a couple of weeks - which would be about now, however, reports on the
Forums are that it will take considerably longer.

The Cancer Connection
- The 12th International Conference on Malignancies
In AIDS that took place in late April just posted abstracts from the conference. (Before we get to that take note that this was
the 12th Annual Conference not on AIDS - but on malignancies
in AIDS. HIV is, of course, the biggie - besides cancer it causes a host of
conditions but HTLV, the other lesser known human infectious retrovirus, is
associated with both cancer and neuro-immune disease. Given that it's probably
no wonder that Dr. Mikovits
thinks in multiple dimensions (and multiple diseases) when she thinks of the
third human infectious retrovirus - XMRV).
Dr. Mikovts, Dr. Ruscetti and Dr. Lombardi co-authored an abstract called "Repeated Detection of Infectious Xenotropic Murine Virus-Related
Virus (XMRV) in Human Neoplasia and Neuroimmune Diseases". In it they note that XMRV's
close cousins -murine leukemia retroviruses - cause cancer in mice by
activating 'oncogenes' (genes that cause cancer) when XMRV inserts itself into the cells genome.
They then describe a case in CFS where they believe XMRV insertion resulted in a B-cell lymphoma. (They apparently did this by demonstrating XMRV
in this person has inserted itself next to
a gene known to cause B-cell lymphomas (?))
Retroviruses don't necessarily insert themselves
in one part of the genome; in different people and in different cells they will insert
themselves in different parts of the genome; this case study suggests that XMRV
can, at times, insert itself in a particularly dangerous part of a cells genome.
Another study suggested that this does not happen often with XMRV. Still,
findings like this will definitely up the ante on XMRV and should push more
researchers to study the virus. Hopefully the study will be published in the
near future. For more on
'insertional mutagenesis.

Patient Advocate See's The Wall's Tumbling Down
(But A Dark Cloud Gathering As Well) - The Patient Advocate is clearly tied
into some of the action at the WPI. He sees alot of positive things occurring in
the near future; a positive NIH study to be released soon, a new serology test
by the WPI (that hopefully puts the contamination issue to
rest), the opening of the WPI in the next few weeks, XMRV being validated. He sees research
accelerating, treatment trials on the horizon, etc.
He also sees a dark cloud forming - Sen. Harry Reid's election (or lack of it) in November. Harry Reid,
the Whittemore's biggest champion, is in the fight of his political life in Nevada. Harry Reid is someone we
definitely want to stick around. (The PA believes Harry Reid made sure that the Alter paper is going to be
released...Who knows?). This is what the PA says about Harry Reid
"No matter what one thinks
of Harry Reid as a politiician, there is one certainty. Harry Reid is the best friend of CFS/ME in the
United States government. It is fair to say that without Reid the WPI building would not have been built
and that perhaps XMRV itself would not have been discovered. Harry Reid is currently in a close struggle
with a Tea Party challenger. Anyone in Nevada who has CFS/ME, or knows anyone with CFS/ME, had better think twice before voting to oust Reid. It was no coincidence that Obama was in Las Vegas last week (campaigning for Harry Reid) on the very day that news arrived that the Alter study would be released soon. One can surmise that Reid and other Nevada representatives were in meetings last week shortly
before this with the HHS regarding the absurd "scientific hold" of the NIH study."

Trine Tsouderos on XMRV and CFS (er Judy Mikovits) or "How Not to Speak to a Reporter" - Trine Tsouderos has written another
hard-hitting article for the Chicago Tribune purportedly on XMRV/CFS but, like
the last one, much of it is really about a researcher she percieves to
be over the top - Dr. Mikovits. After noting that the 'joyous mood' has soured, she
writes that in response to the failed studies Dr. Mikovits has accused other researchers of bias, has stated that XMRV could be
the worst epidemic in US history, has stated her finding is being ignored, that the government is more interested in the XMRV/prostate
connection than the XMRV/CFS connection, and that XMRV is found in disorders such as
autism and multiple sclerosis for which there is not yet published evidence.
In a particularly damaging statement Dr. Mikovits was reported to state she had to "play
the autism card" because the government was neglecting CFS. (If that was
the intent
-it backfired mightily; appearing at the Autism One conference only cast further
doubts on Dr. Mikovits in some quarters, which, of course, casts further doubts,
in some quarters on the CFS/XMRV connection; ie it doesn't appear to have done CFS
patients any good at all.) Tsouderous notes that while these some of her
comments have been greeted by the patient community they have raised eyebrows amongst her
peers in the research world.
Many of Dr. Mikovits statements may very well be true but in the context
of a short newspaper article that doesn't have the space to flesh
them out more they can come off as defensive and, indeed, are the type of juicy
comments journalists love to build story lines on. Whether or not Trish
Tsouderous should have written this story she was given all the ammunition she needed to write it. In the
Chicago Tribune, at least, (and perhaps the LA Times and related newspapers - we
shall see) the story is no longer about CFS and XMRV it is about an outspoken,
somewhat off-kilter CFS researcher and XMRV; not a positive story
line for the CFS community.
The article also briefly explored whether there were basic problems with the
study. Dr. Coffin, a supporter, conceded that this could be so "Right now it is
chaotic...It is not impossible that there is something fundamentally wrong with the initial study.
Everything is on the table." Tsouderous then noted another retroviral finding that took 4 years before the error
was discovered. There was no answer, however, to Dr. Mikovits and Dr. Lombardi's claim that as long as
labs are able to pick up evidence of an immune response to the virus contamination
is not feasible. This is the core counter-argument
to contamination that no one, publicly at least, has been able to counter.
-
Blood Advisory Panel Speaks - When the Blood Advisory Panel on XMRV speaks
people apparently listen. Amy Dockser Marcus's report at the
Wall Street Journal, in fact, simply talked about what the researchers
were going to talk about. Intriguingly, she stated
that one reason the research is moving is so slowly is that researchers are beginning to wonder
whether the virus present in people with CFS is the same one they are studying in the lab. The question whether enzymes found
in immune cells in the blood are altering the genomic content of XMRV such that it is different from reference XMRV
samples in the prostate, was explored in "A Different Kind of XMRV". Marcus noted that that question will be
addressed by the working group as the studies continue.
Medscape on the Blood Advisory Panel's Report - there is some new news here. The finding that the viruus spreads rapidly through the
bodies of primates inoculated with the virus indicates that blood tranmission in humans is probably possible, and that if XMRV is
in the blood supply, its going to be transmitted. The primate study found that
XMRV hits epithelial prostate cells early and goes on later to infect the T and
B cells in the blood. (No word on XMRV's ability to infect nervous system
tissue). One new bit of information was Dr. Silverman's report that XMRV is
found in the semen and thus theoretically can be transmitted sexually. He noted several possible reasons for the discrepancy between
the study reports.
On a side note the report on the CFS/XMRV connection noted that
"In CFS, the evidence has been less: Only 1 study of the 5 that have been
done found a link between XMRV and this debilitating disease." What was noteworthy to me was the reference to CFS as
'this debilitating disease' - suggesting that this important medical venue is getting it about the costs of CFS.
CDC - Demonstrating the uncertainty present
within the Working Group, the CDC representative Dr. Hendry, stated that even
after using 'ultrasensitive' assays the CDC was unable to find XMRV in CFS and
then discounted all of Dr. Silverman's
factors - basically suggesting that the search for XMRV in CFS was over. (The CDC
essentially stated the same thing in their study but took a
softer line on their website - stating more research needed to be done.) Amongst
this group of professionals Dr. Hendry appears to have opted for the first
approach. We know the CDC looked for XMRV in CFS before the Science paper was
published and was unable to find it and nothing that's happened in the last 9
months has changed their opinion.
National Cancer Institute - the NCI has reportedly poured over a million dollars into the developing assays for XMRV and it appears to have
paid off. Dr. Stuart LeGrice noted that the NCI developed what came to be the gold standard for HIV and he believes they have done the same for XMRV. Medscape reports
him saying "The HIV single copy that was developed at the NCI is regarded as the gold standard assay. We now believe that
we have an equivalent assay for XMRV." This, of course, would be a huge breakthrough for the field and,
if it is validated, should quickly
clear up alot of the confusion regarding XMRV. The assay is now being tested in labs across the world in Sweden,
Australia, Vietnam, and South Africa. He stated "Developing an assay is one thing, but transferring it to a laboratory where it can be
reproduced is clearly important when we are talking about single copy
assay. Contamination is a huge problem, and the ability to transfer these reagents is very important".
As we've come to appreciate XMRV is apparently not an easy bug to deal with in
the lab.
NIAID - the big center of retrovirus research in the NIH stated.....nothing. The Institute that missed out on the
developing the AIDS Assay has preferred to sit on the fence with XMRV ceding ground, once again, to the NCI. Friends matter in
science, as they do everywhere. The NCI is involved because Dr. Mikovits and the Ruscetti's are involved and the Institute has
reportedly poured an enormous amount of money into XMRV over the last year. If XMRV turns out to be a quirky virus
it will only be understood because a group like the NCI put enough money into it
to figure it out. The CDC says it's over. Dr. Le Grice suggests they've hardly
started. It's our luck that this time we do have an Institute willing
to dig deeply into this virus. They may very well save XMRV's bacon in the long

Ten XMRV Resources for CFS - Jody Smith of EmpowHer highlights 10 XMRV
resources for CFS on her latest blog
- The (Altered?) Alter Paper Out Soon - in a reply to letter to
the NIH expressing concern about the withdrawl of the Alter paper, Vivian Pinn,
director of the Office of Research For Women's Health (ORWH), which is
responsible for ME/CFS research at the NIH, stated
that they expect publication soon. "As
typically occurs in the process of publishing scientific findings, the authors
are presently addressing issues raised during the peer review of the manuscript
and expect publication soon." Other studies
not associated with the NIH/FDA are purportedly in the pipeline, including one
reportedly that has positive findings.

Dr. Holtorf Queries ME/CFS Community: How are Antiretroviral Treatments Working?
- Dr. Holtorf, a prominent ME/CFS physician in Southern California, has found that
most of the patients in his practice who test positive for XMRV also test positive for other pathogens such as EBV, HHV6
and Lyme. (This does bring up the cohort question again - is XMRV mostly found in immune whacked out, pathogen
ridden patients?). If you'd like to help answer Dr. Holtorf's question please do it
on this thread. (If you are a Forum member you can also PM him).
- WPI Opening in
Less than a Month! - With all the buzz about XMRV we've missed the fact that
construction is almost complete and the WPI is about to open! The only
University ME/CFS Treatment and Research Institute in the US, WPI is a testament
to Annette and Harvey Whittemore's persistence and vision, and a landmark
achievement for chronic fatigue syndrome. The facility will be open Aug 21st
from 10-12am for viewing.

Dr. Teitelbaum On XMRV- Dr. Teitelbaum gives his view of the XMRV situation
in a blog on Psychology Today. He notes that other mysterious mostly female
disorders of that past such as MS encountered the same difficulties from a
mostly patriarchal medical establishment that CFS is encountering now. He states
that the 'absence of evidence' in some studies with XMRV is not the same as the
'evidence of absence' as he believes the wrong techniques were used.

International XMRV Workshop Lineup
- Lineups can tell you a lot. The lineups tell you who's in and
who's out. I remember a CDC lecture at the Reno conference; it was a nothing
lecture but there it was in prime time. Why? Probably because the CDC had to be
given some space.
Dr. Mikovits is not speaking - despite the fact that it was
her and Dr. Lombardi's paper that ultimately made this conference possible. Is this
a snub to Dr. Mikovits? Certainly it could construed as such. It may very well
reflect her outspokennes on behalf of CFS patients. The
most disturbing aspect of the Workshop, however, may not be that Dr. Mikovits is not speaking but
that William Switzer of the CDC is giving a
presentation on assays for XMRV. Still, despite the WPI's total absence from the
lineup, the Science paper is well represented in the conference, however, and
the lineup overall is quite strong.
The organizing committee had Dr. Coffin, Dr. Silverman and Dr. Grice from
the National Cancer Institute on it - all people who would be happy to the
Science papers findings validated. The
Scientific Committee
contains a
wide swath of researchers from Dr. Bannert to Dr. McClure to Dr. Mikovits and
Dr. Vernon. Here is the lineup.
• Dr. Kate Bishop, NIMR, London, UK - Host Restriction Factors- Dr.
Bishop was the co-author of what Dr. Mikovits believes is one of the most
important papers in the field. Hers and another paper indicated that enzymes in
T and B cells in the blood are able to alter XMRV's amino acid makeup, thus
rendering it unable to replicate in those cells. Dr. Mikovits believes the
altered makeup of these cells is obscuring researchers ability to find XMRV.
• Dr. Sam Chow, UCLA, Los Angeles, USA –Viral Integration
- where XMRV integrates itself into the DNA of cells can have a huge effect on
how pathogenic it is. XMRV's murine leukemia retrovirus cousins integrate
themselves next to and then turn on genes that can cause cancer - causing cancer in mice. He is studying
to see if the same is true in
XMRV.
• Dr. John Coffin, Tufts University, Boston, USA –Basic Virology
• (Keynote lecture) Dr. Eric Klein, Cleveland Clinic, Cleveland, USA –Prostate
Cancer - why the 'Keynote Lecture' is on prostate cancer is beyond me.
The finding of XMRV in cells near prostate cancer tissues spurred little
research; it was the Science paper on XMRV in CFS and healthy controls that got
the research world humming. Maybe next conference Dr. Mikovits will give the
keynote lecture.
• Dr. Robert Silverman, Cleveland Clinic, Cleveland, USA –Animal Models
- finding an animal model they can use to study this virus is, of
course, a vital part of learning about it.
• Dr. Ila Singh, University of Utah, Salt Lake City, USA –Pathogenesis
- a hot topic for the Dr. from Utah. Dr. Singh is currently engaged
with Dr. Bateman and Dr. Light on an XMRV/CFS study....We hear the results are
in.....
• William Switzer, CDC, Atlanta, USA –Assay Development
- This is the 'problem lecture'. William Switzer (who is apparently
not a doctor, never having earned his Ph.D), was never
able to find XMRV in the WPI's samples for the CDC. Since finding XMRV is
the KEY QUESTION at the moment this is easily the most important lecture for the
CFS community. He will be laying out the guidelines for finding XMRV! An
alternative would have been to have Dr. Bagni from the WPI, who is actually able
to find the virus. (yes, she is real Dr.) Or did they feel obligated to have someone from
the CDC on board?
• Dr. Frank Ruscetti, National Cancer Institute, Frederick, USA –Chronic Fatigue
Syndrome - if they're going to have someone speak on CFS it may
be better to have Dr. Ruscetti, with his 240 publications and renown
in the field, to do it than Judy Mikovits with her 40 or 50 or so publications.
despite the fact that he knows much less about the subject, because they will
listen more closely to him. I would think he is probably http://www.facebook.com/notes/xmrv-global-action/1st-international-workshop-on-xmrv-pathogenesis-clinical-and-public-health-impli/421411181796
the most distinguished researcher to ever speak for us.
• Dr. Ellen Sparger, University of California, Davis, USA –Vaccine
Development - are they already thinking about vaccines seriously or are
they just covering all the bases?
XMRV Global Action
is organizing a drive to communicate the patients community's displeasure at Dr.
Mikovits not giving a lecture at the Workshop.

July 21st
-
Dr. Goff Talks - Dr. Goff talks with Dr. Kathy Miller on Sound Medicine in an audio clip.
He emphasized that researchers have been working on XMRV's close relatives (the murine retroviruses) since the seventies so there
a wide body of knowledge on this general type of retroviruses. The most pathogenic aspect of these retroviruses is their ability
to insert themselves in places in the DNA that end up turning on genes that cause cancer. (That has not been found yet in XMRV).
Getting to CFS at the end of the
clip he called the association
with CFS 'very exciting' and said it was a tentative correlation but then stated he still felt it was 'very exciting'. (Two 'very exciting's in two
sentences.....) He then made a very strong
statement about the possible link between XMRV and ME/CFS saying
"this is the kind of disease that a retrovirus like this might cause". (Contrast that with Dr. Reeves, Dr. Wessely, Dr. White and Dr. Lloyd statements
that ME/CFS is NOT the type of disease
that a retrovirus would cause) and then followed up with 'we could easily imagine it could be the cause of the symptomology of this chronic fatigue syndrome".
Then he kicked the door wide open stating "I think in the grand scheme of things there's the potential that alot of diseases that we
don't understand will ultimately be attributed to viral infections. This would be one of the most exciting and clear cases if it comes to pass". Whew!
Did I miss something in his earlier statements or does he sound alot more positive about XMRV than before? It's always easy to read too much
into these short interviews but one has to ask oneself if something has gotten our rather cautious retroviral expert a bit more
excited on the future of XMRV and CFS. Dr. Goff is a professor at Columbia University.... there is an XMRV study going on there...(?)
- The (Almost) Year of XMRV- How long has it been since the
Science Paper kicked off all the excitement? According to the Countup
Timer to your left it's been 271 days - almost exactly 3/4's of a year. This
will indeed be The Year of XMRV.
July 20th
-
FDA Speaks - the FDA will be communicating its findings to the Blood Products Advisory Committee on Monday. They will be reporting on
the progress of the Blood Safety Working Groups efforts including "ongoing validation studies of XMRV panels, updates of research efforts on
test/panel development and other studies". This appears to be the biggest federal effort to understand XMRV. It involves six labs (two at the FDA), the WPI,
BSRI (used in the CDC study), the CDC and a National Cancer Institute lab. (Note no one from the National Institute Of Allergy and Infectious
Diseases (NIAID) is involved. The FDA, of course, is the home of Dr. Alter - whose paper, reportedly, will be published soon. We should get some
information on how this important study is progressing, and, who knows - possibly some information on the Alter paper.
Dr. Mikovits, reportedly, will attend. She told me that the completion of the
studies is several months away.
-
XMRV Testing in Europe Now Available - RedLabs in Belgium has licensed the
proprietary XMRV test from the WP technologies, a subsidiary of the Whittemore
Peterson Institute. They are offering the co-culture test. In this test the
blood sample is putting contact with a cell in which XMRV readily grows. (XMRV
does not appear to be able to replicate much, if at all, in the immune cells in
the blood. In the co-culture test the immune cells gathered from your blood are
put in contact probably with a LNCap cell in which XMRV replicates. After
whatever XMRV is present grows for a couple of days PCR or Western blot are used
to search for it. A serology test is forthcoming.
July 19th
- Weirdness
in the UK? - Somehow Dr. McClure, despite not knowing an ME/CFS patient from a
hole in the ground before XMRV showed up, and despite vowing not to have
anything more to do with such a fractitious bunch of patients, has become the
most public UK reviewer of the CFS/XMRV question. In her latest paper -
published in Expert Reviews of Molecular Diagnostics - she provides her overview
of the situation. She notes the differences and similarities between some of the studies,
notes that viruses could be a cause of CFS but then skewers the WPI with this
sentence "Only
the study from the Whittemore Peterson Institute [1] was able to detect XMRV
sequences following single-round PCR, indicating that copies of the XMRV genome
were not in short supply. All the others found it necessary to employ a nested
PCR, a modification of the standard reaction designed to enhance sensitivity and
specificity." (In nested PCR you do two 'runs'; the first one
is designed to pick up signs of the virus - the second one is designed to
amplify those 'signs'. According to Dr. McClure, XMRV was so 'present' in the
blood of the WPI samples that further PCR work was unnecessary. This, of course,
is greatly at odds with Dr. Mikovits repeated statements that XMRV is not only
rare but hard to find.
Megan on the Phoenix Rising Forums,
however, pointed out that the Science article states
"we isolated nucleic acids from PBMCs and assayed the samples for XMRV gag sequences by
nested
polymerase chain reaction
(PCR) (5, 6). Of the 101 CFS samples analyzed, 68 (67%) contained XMRV gag sequence."
The supporting material section of the Science papers states "To avoid
potential problems with laboratory DNA contamination, nested PCR
was performed with separate reagents in a separate laboratory room designated to
be free of high copy amplicon or plasmid DNA" . It seems impossible
to reconcile Dr. McClure statement with these statements making one wonder if
Dr. McClure simply made an mistake of enormous proportions (?)
- XMRV Studies Outlineddd
-Neuroskeptic is, well, a skeptic, but this UK neuroscientist has done a great
job at outlining many of the important features (types of patients used, types
of tests, etc) of the XMRV studies to date. If you want a handy way
to compare central features of the studies

- Cleveland Clinic
Back Into the XMRV Fray Again? FernRhizome on the Phoenix Rising
Forums reports that a doctor told her, during a recent trip to the Cleveland Clinic, that they hope to start a
new study on XMRV and CFS in a couple of months. We don't know what this study is about but this appears
to be particularly good news for XMRV, because the Cleveland
Clinic's Dr. Silverman was co-author of the Science paper which, of course, has come under attack. One would presume that no
new study would be underway until any issues Dr. Silverman had with XMRV (if any) were resolved.
Apparently the Cleveland Clinic is confident about XMRV and moving forward.
- XMRV Journalist Explored - Amy Dockser Marcus has been leading the way (sometimes alone) on XMRV and CFS for the Wall
Street Journal
and has broken several important stories. Now, the Patient Advocate, takes a deeper look at Amy and is very impressed. Check out

outlet here.
July 16th
XMRV
CFIDS Assocation Webinar - Dr. Racaniello and Dr. Bateman talked XMRV (mostly) at the CFID'S Association Webinar
on Wednesday.
DR. RACANIELLO gave us a bird's eye of retroviruses. Right now there are two models for
human infectious retroviruses; HIV, which replicates madly in immune cells and sends millions of virions
into the blood to infect more cells and HTLV-1, which does not replicate much and does it's
damage by turning on bad genes in the cells it is found in (sometimes turning them cancerous).
He noted that XMRV, at this point, seems more HTLV-like - it's present in
small numbers in the blood and doesn't appear to be replicating much.
(This could be misleading,
however. XMRV could be replicating madly in some other part of the body.
We know that the immune cells contain APOBEC3 enzymes that 'edit' XMRV sequences - thus
largely shutting it's replication down but that prostate cells do not
contain this enzyme allowing XMRV to replicate in them. Primate studies of XMRV indicate that XMRV infects many cells - it
uses a receptor commmonly found on cells to enter them - and that, upon infection it spreads rapidly
throughout the body. It could be flourishing in areas of the body that
have not been studied yet).
(XMRV, then, could look like HTLV-1 in the blood but like HIV elsewhere.)
This is an important question because its mode of action determines how easy it
is to treat. It took years to learn how to treat HIV but eventually, for those
able to get the drugs, it's eminently treatable because the stages of the
replicative process give researchers different shots at it. You don't need to
kill HIV to get better - you just need to stop it from replicating.
HTLV-1, on the other hand, effects the body simply by being present in the cell
because it appears to turn on genes in the cell that can cause the cell to become cancerous. Stopping this
type of virus presumably requires killing all the cells it is present in, which is very difficult to do.
(One study
that looked at XMRV's effects on genes in the cell did not find found
that it inserted in areas of the genome where it could turn on 'oncogenes'; ie genes that
turn cells cancerous. XMRV, on the other hand, could trigger an immune response in some
individuals simply by being in the cell. Or, as noted earlier, XMRV could be acting like HIV
in a different part of the body - which is the preferable scenario,
oddly enough, treatment wise.)
Why the varying study results? Dr. Racaniello laid out four possible reasons and emphasized the last; patient
selection/geographic differences in viral prevalence/ sequence differences in viruses in different
regions and the lack of standardized testing. He noted that, with regards culturing the virus for PCR, that
that was not done in the original Science paper and that the validation studies have, in general,
followed the approach taken in that paper. If culturing is necessary to find the virus via PCR he urged
WPI researchers to publish that information.
Time - He also noted that finding the correct treatment takes time. HIV was isolated in 1984. It took about a
year to develop the first antibody test. AZT was not discovered until 1989 and the HAART therapy that has
proved so effective became available in 1995, after over ten years of intense scientific effort. (Dr. Klimas and others
believe that the process could be sped up significantly with XMRV)
DR. BATEMAN - Dr. Racaniello was clearly comfortable at the mike in a kind of low key way. Dr. Bateman, on the other
hand seemed almost effervescent in comparison. She's not always so enthusiastic but for whatever reason she
seemed to be enjoying herself immensely this time. She is deeply involved in the Light/Singh study and hoped to be able to
provide some information on it by now, but alas, could not. Her talk, however, was very engaging.
No 'True CFS' At the Clinic - Dr. Bateman is known for her careful
analysis of her CFS and FM and idiopathic fatigue patients and she demonstrated
her ability to differentiate different types of patients in in spades in her talk. Knowing that
stating so was going to
tick off some people she declared that there is no 'true CFS' - that what we have,
at the moment, are a bunch of educated
guesses.
Interestingly she noted that the broad range of patients she sees at her 'Fatigue Consultation
Clinic' fit the (dreaded) Empirical Definition more than anything else; that is, she sees a lot of different patients
and some of them fit the Fukuda criteria and some fit the Canadian Consensus Criteria but
all of them fit the Empirical Definition. These are the broad range of
'idiopathic fatigue' patients that doctors see. They are all sick, they have all
presumably seen many doctors in their search for an answer. These are the 4 million or so really fatigued people in the US that
the medical profession simply does not have an answer for. (If the CDC and Dr.
Jason's studies are correct then about 50% of them have not seen a doctor for
their problems; that leaves about 2 million people in in the US who have seen a
doctor for their condition; most of whom have probably gotten no relief).
Dr. Bateman did
note that the Empirical Definition does appear to allow in more depressed
patients. She was speaking as a clinician not a researcher and she did not endorse
the Empirical Definition as a study tool.
(As an aside, the Empirical definition
casts a wide net and it does, as Dr. Bateman indicated, it may very well pick up the broad class of patients with mysterious
fatigue that doctors see at the office. As such it could be an effective way to
find these people and then break them up into their constituent subsets. Except
for one study the CDC, however, never chose to attempt to attempt to do that in a
meaningful way - instead, they simply proclaimed that they were all just CFS patients.
Not attempting to subset these patients, was, as you'll see as you follow Dr. Bateman,
a huge missed opportunity. Then, again, the CDC hasn't been particularly
interested in ME/CFS physicians opinions.)
Check out the different types of 'CFS patients' who end up at her office.
- The In-betweeners - these
are people in the early stages of multiple sclerosis, autoimmune diseases, neurologic conditions,
etc. who don't
quite fit the criteria for those diseases but get shoved into the CFS basket until they do.
- The Misdiagnosed - these are people who have a condition that physicians have missed. She
described one woman in her late 60s with horrible fatigue and exercise intolerance who was suffering from
coronary artery disease and having a bad reaction to Cymbalta.
- The Complex CFS Cases - these are people who have CFS but also have a host of other problems - which
make it difficult to tell what is causing what. She related a disturbing story of a skinny 15-year-old
who returned to her office several decades later, severely obese, with chronic dental and other infections, poorly controlled diabetes and sleep apnea. She asked - should this person,
with all her problems, be in a CFS study?
- The fluey, pathogen ridden, immune system blasted subset - The original definition of CFS in the US, the Holmes
definition, focused on the sudden onset, flulike symptom, natural killer cell reduced group. She noted that
this group in appears to have different gene expression findings than the other groups. Is this true CFS?
- Postexertional Malaise Group - the above group may sound like CFS but, if Dr. Bateman was to chose any group
to represent CFS, she would choose the group of people (presumably without another comorbid
conditions like diabetes) that suffer relapses after exercise.
- Cognitively Challenged Group - is cognitive dysfunction required to meet the definition
of chronic fatigue syndrome? Some people think so and some people don't. This
is not a prominent feature for everyone.
The Onset Question - And what about onset? Dr. Bateman noted that
there are several types of onset
- EBV (infectious mononucleosis)
during Adolescence onset group appears to be different from other groups. They tend to have postural orthostatic tachycardia
syndrome (heart races upon standing), headache and sleep disorders but not as much
cognitive dysfunction and appear, if I heard her right, to recover better than other groups.
- The sudden onset cases in middle age group, on the other
hand, don't have as much POTS and are more difficult to treat.
- The Stepwise Onset - the stepwise onset; people who are in fragile health and slowly, through a
series of infections or other problems lose more and more ground until they have CFS.
She didn't mention the gradual onset (in
otherwise good health) group. I am a member of that group; my health was superb
at the time, my onset was not acute but it wasn't that gradual either - a matter
of a few months, as I remember. It would not be that difficult to delineate these groups out, and, in fact, in the Patient Data
Repository program that we're working on, we're going to try and do that.
The Positive Effects of Controversy - Dr. Mikovits also outlined how all the controversy over
XMRV has helped XMRV research and chronic fatigue syndrome in general.
- Every Paper Gets Better - everytime a new paper comes out and the research groups studying
XMRV feel compelled to 'raise the bar'. It's was clear that she and her co-researchers in the Utah
XMRV study will attempts to make their study stronger and more comprehensive than the studies
that have gone before it.
- An Inadequate Research Definition Gets It's Day in the Sun - the broad research community finally takes a look at a
a basic question that, 25 years later, is still unanswered: Just What Is CFS?
- Chronic Fatigue Syndrome is a hot topic. XMRV has dragged ME/CFS from being a niche topic that
few researchers knew anything about to being in the spotlight. Researchers, doctors and public officials
are finally learning a little something about CFS and some of them are getting engaged. She talked about a
microbiologist helping out in the study who ended up spending days in her clinic just learning about the
patients. Dr. Mikovits said that she one day turned to her and said "We have to help these people"!
Indeed that
has not been an uncommon reaction amongst professionals who, for whatever reason, get close to
CFS patients. Stacey Stevens at the Univ. Of Pacific, reports that her students there love to learn
about ME/CFS patients - partially because they're so interesting! Dr. Ruscetti is a case in point. Dr. Mikovits
asked him if he felt she should take on ME/CFS (long before XMRV showed up). He didn't know anything
about the disorder but after several days visiting gave her an emphatic 'Yes!'. In his recent
talk, he stopped at one point and stated that "And they can remember the day and the hour in which
their life changed", something he clearly thought from a medical perspective
was just fascinating... Of course, CFS patients really are fascinating in so many ways; yes
, they present problems that the medical profession
just doesn't know how to deal with, but that makes them fascinating to the right kind of researcher. They are inherently
interesting. Hopefully the exposure
that XMRV has brought will bring more researchers, like Dr. Bateman's microbiologist, into the field.
- The Big Research Players Are Interested - CFS research has
often been the realm of researchers who have a personal interest in the field
for one reason or another. They are working in small groups or by themselves.
They're often not working at the major Academic Centers that are the central
drivers of research in the US. XMRV, though, has gotten major academic centers
finally involved in studying CFS and she ticked off a list of them.
- Pharma is Poised to Act - Pharmaceutical companies spend an enormous amount of money on research. If XMRV
turns out they are eager to jump in. The huge success of drugs for Fibromyalgia apparently really
opened their eyes and XMRV's potential to leap disease boundaries must have them salivating. Dr.
Bateman noted that the pharmaceutical companies also play key roles as educators.
- Inspired the Community to Donate - she also felt the discovery had inspired the Community to donate
is it never has before, which is critical to efforts such as hers.
- CFS is in the Media - the media may drive researchers nuts but being in the media gets CFS in the public
eye and can play an important role in getting more funding.
QUESTIONS
Dr. Bateman got 'muted' and no one could figure out how to unmute her and so Dr. Racaniello got the questions.
Contamination? How to tell if it was present? That drew a little laugh - good question, indeed! Dr. Racaniello was
clear, however, that he could find no reason to believe that contamination was present. For one thing
XMRV in samples does differ slightly - which is not the kind of thing you would see in a contaminant. Is the blood the right
place to look for XMRV? Not necessarily, the blood is the most convenient place to look for the virus but
it could be present in higher numbers elsewhere. What if XMRV in CFS doesn't pan out? He felt researchers would
continue studying XMRV and he felt their interest in CFS has been reinvigorated as well.
Check out the Webinar here. It will be up on Youtube next week.
July 14th
- the
XMRV Webinar with Dr. Racaniello and Dr. Bateman and Dr. Vernon is tomorrow. It's at
an earlier time that usual - 12pm Eastern Time/9 AM Pacific Time.
Dr. Racaniello
talked about XMRV in a recent interview here.
- The Grey Lady Stirs
- Several weeks after the Alter paper controversy started it finally hit the
New York Times. There's not much new here on the controversy itself although, as always,
the Times does an informative article. The Times has been good to CFS patients
of late, and here they quote Hillary Johnson and Annette Whittemore, among
others. Dr.
Stephen Monroe of the CDC, who appears to be overseeing the effort on CFS, either was misquoted or displayed a profound ignorance of the subject with the reporter stating he said
that the agency believed that infectious agents
could be one of many possible triggers for the disease. We do think the CDC understands that the question as to whether
infectious agents 'trigger' this disease has been settled many moons ago. (The CDC funded the Dubbo studies which
proved it (not that it needed to be proved)). Stating that he was not surprised at
the patient uproar over the papers being withdrawn Dr. Monroe said “This is a very well-informed and highly connected patient
and advocacy population, and whenever there’s any new information, it’s circulated widely,”
- XMRV Action Site - to promote news,
information and advocacy regarding XMRV is up and is in the process of getting
put together. Check it out here.
- XMRV Hits an AIDS
Review Journal - XMRV has shown up in the "Hot News" section of a medical
journal called AIDS Review. In this short and very technical article the authors
take XMRV very seriously and bring up some interesting points, one of which is,
the medical commmunities ability to determine, by using longitudinal samples, if
XMRV infection is related to disease onset (does it immediately trigger CFS?),
or if the initial infection takes years to progress to CFS (as occurs with HIV
and AIDS). This presumably simply involves testing old samples of blood, finding
XMRV and then contacting the sample donors to see how they are doing. (It's
amazing what the medical community can do if they decide to spend some money on
a disorder!). More on this later.
July 13th
- VIP Dx Serology Antibody Test - is slated for early August. The test has been pushed back - something that should
come as no surprise to anyone who's been keeping an eyes for XMRV for the last 8 months.... Because a good antibody test appears to be the 'antidote' to this talk of contamination, the appearance of a solid antibody test
should be a big step forward for the WPI. They, of course, are not the only ones working on an antibody test; Dr. Singh at
Utah is, Abbot Labs are, the DHHS Working group is and other groups probably are as well.
The test will reportedly cost $250 alone and $600 if you want a culture test
done with it.

-
A Different Kind of XMRV? Dr. Mikovits and Racaniello Talk! - Check out this new article on XMRV
from Phoenix Rising in which Dr. Mikovits provides
some startling new information on why researchers may be missing XMRV in their studies.
Dr. Racaniell talks about PCR and why he thinks researchers may be missing the
bug in their studies.
- Dr. Deckoff
Reports - continued steady progress for both her and her daughter after 4
months on antiretrovirals.
-
National ME/FM Action Network reports that Dr. Jolicoeur, the Canadian
retrovirologist who was unable to find XMRV in the first go-around is having
another go at it.
July 10th
- Alter Paper on its Way to Publication (Unchanged?) - The CFIDS
Association reports: "The
[FDA/NIH] researchers have conducted additional experiments as requested by the
reviewers, and their paper is expected to be published in the Proceedings of the National Academy
of Sciences within weeks." Sources to CFS Central say that the
researchers' conclusions have not changed (!).
- Don't forget - the
XMRV Webinar with Dr. Racaniello and Dr. Bateman and Dr. Vernon happens in
the 15th.
- Coming up soon - an interview with Dr. Mikovits and Dr.
Racaniello about XMRV.
July 8th
- Investigative Reporting Take II - first Hilary Johnson reported on some of the background elements of the
DHHS imbroglio involving the Alter paper and the CDC study. Now Mindy Katei at CFS Central has filled in more of the
blanks. She reports that the CDC was the driving force behind the yanking of the
Alter paper not the DHHS. The DHHS officials were apparently asleep at the switch as the two opposing papers raced ('raced' -right!) towards
publication. It was the CDC that played watchdog, and alerted senior public officials at the DHHS about the impending
clash of results, and then pushed them to ask the editor of PNAS to request more tests. Mindy reports that the
editor-in-chief of the publication (PNAS) said it was highly unusual for a paper be
withdrawn after getting to
that stage of publication. She also reports being told that the DHHS has complete control over
Dr. Alter's work and has no obligation to publish it at any time.
The Human Touch -
The CDC reported that they could find XMRV in a
laboratory sample and thus should be able to find it in a human sample as well. Dr. Mikovits take on this couldn't be any clearer.
Citing the differences in sensitivity between analytical;ly (lab) derived assays and clinical
(human) derived assays Dr. Mikovits stated"
“The CDC assays as published in Retrovirology would absolutely not detect XMRV".
Another Player in the Mix? - It
was reported that another lab - possibly Dr. Singh's - was able to find the pathogen in
those samples. Now Mindy reports that (a) yet another lab
was able to
find XMRV in those samples and more importantly that (b) the CDC was sent XMRV positive samples from another lab. This, of course,
would mean that another lab has found XMRV in the blood of human subjects - something that the WPI it
has only, thus far, been able to do. We have reports that Cooperative Diagnostics
has provided the CDC with the blood from more severely ill CFS patients and that
a paper with the results from that study is in the works but all indications,
thus far, were that Cooperative Diagnostics was unable to find XMRV in its
samples as well. If Mindy's report turns out to be accurate then either
Cooperative Diagnostics found XMRV in it'sif samples or yet another lab has
entered the fray.
For it's part the CDC stated that they used the
procedures they did because 'no validated' positive XMRV samples exist, which
suggests that they did not consider the samples they were given 'validated' and
we don't know if they found XMRV in them or not. Of course, providing validated
positive XMRV samples that all researchers can use to determine if their testing
protocols are accurate, is a key goal of the big DHHS project, and will provide much-needed clarity
in the field.
One wonders how much one can trust the results of any study before that occurs.
There's much more in Mindy's article including a section from Mary Schweitzer looking at the CDC's
track record with CFS. Check it out here.
-
The Cohort Question (Again...) - While we're focused on the testing
procedures Kim McCleary of the CFIDS Association brought up an interesting fact
about the cohorts being studied. I have no idea how she figured this out but
some additional research revealed that only two of
the subjects studied had acute onset of CFS. We knew the cohort was CFS-lite -
but we didn't know it was this lite - at least as regards viral triggers. The
cohorts clearly can't explain zero positives given the 4% positives in healthy
controls reported in the Science paper but a weak cohort, combined with another problem, say a poor testing protocol, could and would drive the numbers
down further.
What is really wanted and needed is a study
with a strong cohort and good testing procedures. The CFIDS Association study on XMRV
should fit that bill as should the Light/Singh/Bateman study, the WPI's UK study
and hopefully others. The CAA study only contains people with acute onset
because they feel these patients may be more likely to have XMRV; this is the patient group that Dr. Peterson focused on
for so many years in Incline Village.

- AIDS Study Finds No XMRV
- another (sigh) negative study. We heard that researchers are taking a look
at XMRV in other diseases. Some XMRV was found in immunocompromised transplant
patients. Here a large study (almost 1000 people) looking for XMRV in AIDS found
zero XMRV using quantitative real-time PCR. (1000 people! That presumably
illustrates the amount of money available to AIDS researchers. One wonders after
the first 200 negatives why they kept going!? What was the point? The abstract
does say the study was from people who were part of a Multi-center study - so
may be they were at regional differences). We don't know
what sequences they looked for (gag is preferred). My recollection is that nested
PCR is better as well.
July 6th
- Hilary Johnson Speaks Out- Hilary Johnson has just posted a long blog that provides alot of backup information on
the controversies
over the last couple of weeks. According to one of her resources the directors of the NIAID and the NIH as well as administrators
at the CDC, were all involved in the withdrawal of the Alter paper. She reports that the primary investigator
at the FDA was Shyh-Ching Lo and that the paper was near enough to publication for a galley proof to have been sent to the editor's office.
She reports that the Alter this paper was not a surprise to the CDC at all, that three months ago they had briefed the CDC
extensively about the study and it's outcome. The CDC, on the other hand, kept the outcome of their study
close to their vest leaving the Alter researchers greatly surprised when it came out.
The biggest question right now concerns the results of the testing the CDC did on the XMRV samples from the WPI. Hillary
reports that Dr. Switzer proposed a collaboration between Dr. Mikovits, Illa Singh at the University of Utah and the CD
and that Dr. Mikovits sent samples to both Dr. Singh and the CDC. Dr. Singh was
able to identify XMRV positive samples while the CDC did not. (Whether that, in
fact, happened, doesn't appear to be a question any longer; it now
seems clear that the CDC was unable to identify XMRV positives in the WPI sample set). If the effort
was truly a collaboration that we must assume that both the WPI and Dr. Singh are aware of the
CDC's findings.
Conspiracy?
So what is going on? Hillary Johnson casts the events of the past couple of weeks as simply the
latest evidence of an ongoing conspiracy to save face by upper-level bureaucrats that is doomed to
fail. Dr. Fauci, she believes, lacks the 'ethical compass' to do anything more than to worry about his reputation.
If saving his reputation means condemning millions of CFS patients to a disabling infection so be it.
She acknowledges that respected researchers like Dr. Alter will not be swayed by internal pressure
and that the truth will come eventually out. With the withdrawl of the Alter paper, and the coverup of the
CDC's inability to find XMRV samples in the WPI's samples, the CDC and NIH are simply playing a delaying
game that they are doomed to lose.
Or Confusion? - Only time will
tell, of course, but the conspiracy theory has some holes, the biggest of which is - why engage in a conspiracy that is doomed to failure?
If the truth is going to come out - and with all the researchers working on this pathogen - it does
appear that it is going to come out, then why suppress evidence now that will come out later, and in
doing so leave you
looking a) culpable and b) incompetent? Why not simply jump on the bandwagon and save your own
personal reputation and reputation of your institution?
Another question concerns motive; if you're going to engage
in an activity that, if exposed, could damage or ruin your career, you're probably going to have a darn good motive
for doing so. It's clear that no one in the federal government has done well by CFS patients...they have
ignored this disease, they have not funded it, they have not chased down promising leads....their history
is a decidedly ugly one and they have alot to make up for. But covering up a legitimate finding is another story indeed - particularly if it
involves more than CFS patients. The 600,000 or so possibly infected CFS patients have
never been the main for the feds, the big issue driving the Fed effort
on XMRV is the 10 million or more Americans potentially infected with this
pathogen and any conspiracy theory must take that into account. Are senior
officials at the NIH and CDC willing to cover up evidence of XMRV in the healthy
population simply as a means of getting at CFS patients? That seems very
unlikely.
Then there's the face saving question. There is going undoubtedly going to be egg on
the faces of many
Federal officials, and hopefully they will be held to account when the cause or
causes of CFS are validated but. of all the possible factors, XMRV provides a
great escape hatch for them, the likes of which they will probably never see
again. XMRV was, of course, only discovered a few years ago; more importantly, it was discovered using a kind of technology that only became available
a few years ago. Sure it's possible that if researchers had looked really hard at CFS
samples for pathogens they could have found it but XMRV didn't show up even in
the one group that did look really hard for pathogens - the WPI. In some ways
XMRV presents a great opportifhttp://www.ncbi.nlm.nih.gov/pubmed/20597166unity for the federal research community to squiggle
out of the CFS mire, with at least some of its face intact.
Putting Stakes in the Sand - Instead of the broad
ranging conspiracy theory to keep CFS patients down a more likely explanation for the events that have taken place
is that everybody thinks they are correct. In this scenario the
CDC tests the WPI samples, is unable to find XMRV in them, believes it knows why and then proceeds
to put its stake in the sand by
publishing it's paper. (In this scenario the CDC believes it can find XMRV and that
XMRV is actually not present in the WPI samples! (How does that happen?))
This is a tough issue; it lends itself to
conspiracy theories...except for the fact that the truth will apparently come
out in the end - hence, there's no logical reason to try to cover something up;
in this game the goal is not to pretend to be right but to actually
be right. Given the situation that appears to me to be the
logical conclusion.
Dr. Alter and Dr. Lo test the WPI samples, do find XMRV in them and proceed to at least try to publish their
work. Yes, that work is withheld due to political pressures but no one doubts
that, pending the results
of more testing, it will not come out and we will know what they found. Dr. Singh finds XMRV in her set of samples and begins her own study, the results of which we don't know yet.
That paper will come out as well as will the work of the DHHS study
overseen by Dr. Mikovits, the WPI's UK study, the Montoya-Columbia study, the
Swedish study, the just funded Hanson-Bell study... and work by Abbot Labs and
Glaxo-Smith Kline and other labs who have a big financial stake in proving that XMRV exists....At the end we will know who was right and who was wrong
and we should know why. (My guess is that the answer will be such a surprising
one that no one will be overly embarrassed.)
This isn't 1993; this is not a
youngish researcher vs the CDC - there are real heavy-weights involved on
both sides. This is Dr. Ruscetti at the NCI,
Dr. Silverman at the Cleveland Clinic and Dr. Alter at the NIH vs the CDC. There are simply
too many good researchers involved in studying XMRV for the truth not to come
out. The CDC has drawn it's line in the sand - it believes it has the goods
on XMRV; the WPI and the other researchers have drawn theirs - they believe they
have the goods on the virus; we will
see in the end who prevails.
July 5thh
-
XMRV SampleGate at the CDC? - More reports have emerged suggesting that the tests the CDC used in their
study were unable to find XMRV in the blood samples given to them by the WPI. The Patient Advocate reported that
for
"The CDC got zero positives with their test, zero for twenty. Another independent lab, using the exact same samples (split) got either 9 of 10 or 10 of 10 positives. At this point the CDC did not question
their methods and plunged ahead, blindfolded, over the cliff. Someday, and let us hope it is soon,
this is going to make an unbelievable and incomprehensible story. In this instance real life trumps imagination.
No one could think up such an absurd situation."
If this turned out to be true, and we still don't know what these
reports are based on, this would be an astonishing situation. It's hard to imagine any lab making such a gross
error. The CDC did show they could find XMRV in low amounts - why, if this is so, they would be unable to recover
XMRV from the WPI's samples is unclear.
John Leslie on the Phoenix Rising
forums several days ago stated he had an e-mail indicating the CDC was unable to find XMRV
and repeated that assertion today. The only report from the
CDC on this subject was Dr. Monroe's dodge of Mindy Katei's question specifically
asking him to give the results of those tests (see below). Is this rumor
or fact? Hopefully
we'll have some more solid information this week.
July 4th
- Mindy
Katei Interviews CDC Personnel on XMRV/CDC WPI Blood Sample Flap Emerging? -
Check out Mindy's interesting email interview with Dr. Stephen Monroe. Dr.
Switzer stated that the blood collection tubes used did not interfer with
pathogen preservation. When asked if the CDC were able to detect XMRV in the
samples provided them by the WPI, however, - instead of providing a seemingly
easy answer - yes, he dodged the question....so now that
question looms larger. We know the WPI provided the CDC with 20 XMRV positive
blood samples. If the CDC was able to find XMRV in them fine and
good....but if they weren't that brings into question their ability to find XMRV
in the blood. We know the CDC was able to find XMRV in plasmids from Dr.
Silverman in a 'background 'of whole blood or PBMC's but that is not quite
the same as finding it in the blood. Might this new virus have some tricks up
its sleeve? The question remains - was the CDC able to find XMRV in the WPI's
samples?
- Patent for XMRV Antibody Test Filed - Dr. Mikovits and the Dr's Ruscetti have filed for a patent for an
antibody test for XMRV. They describe the test as a means for diagnosing XMRV-related diseases which they believe could
include everything from XMRV-related lymphoma (Mantle Cell Lymphoma (MCL), Chronic Lymphocytic Leukemia lymphoma (CLL)) to
chronic fatigue syndrome (CFS), Niemann-Pick Type C Disease, fibromyalgia, Multiple Sclerosis (MS), Parkinson's Disease,
A bi-polar disorder, Amyotrophic Lateral Sclerosis (ALS) or autism. The
application, of course, suggests the group feels it has a finished product. This
appears to be the first diagnostic XMRV patent applied for. We know that several
other groups, including large pharmaceutical labs, are working on
their antibody tests. Antibody tests are monetarily a prize because that is
how pathogens are usually diagnosed in the doctor's office.
- Having it Both Ways: the CDC on XMRV
- the CDC made a strong case in their Retrovirology paper that
the search for XMRV in CFS was essentially over when they said that 'minor differences' in the assays used in
the studies thus far could not account for the inability to find the virus. Besides regional differneces
in XMRV prevalence (it's not in the southern US but is in the Western, Northern and Eastern US????)
they could provide no good reason for the differing results - leaving, by default, operator error by the WPI's/NCI's and
Cleveland Clinic as the sole remaining one.
Would the Real CDC Please Stand Up? - On the website they tell a remarkably different story - stating that
technical differences in the assays used, selection criteria for inclusion of CFS patients, clinical complexities of CFS, and
possible variations in XMRV infection rates among populations in different regions - could all help explain the
differing results. In fact, the authors of the paper raised these issues - only to discount them one by one.
(They did note that additional studies of different cohorts is needed)
The website, on the other hand, emphasized how much there is yet to learn about this newly discovered virus stating
"One important consideration is that XMRV is a newly identified virus, first reported in 2006, and
much remains to be learned about this and related viruses. As additional research is done on XMRV
and similar viruses, it is possible that new findings might
emerge that differ from those reported in the Retrovirology and Science papers"
and that
"Additional studies are needed to further evaluate if XMRV is associated with adverse health outcomes, including CFS".
The authors of the paper and of the website appear to have come to different conclusions regarding
XMRV - something we're starting to get used to in the federal arena. In any case,
the conclusions in the paper are likely to have far more impact than those on
the website.
- WPI Samples Not Used? - The WPI has seemingly been providing
positive samples to everyone and they provided them to the CDC team but you
never would have known it from the paper. In fact it appears that the CDC was
careful not to use any materials from the WPI. They
did, however, get a good deal of material from authors of the Science paper and
other XMRV researchers: they used XMRV anti-serum from Illa Singh, anti - SFFV
antibody from Sandra Ruscetti and an XMRV plasmid from Dr. Silverman.
July 3rd
- Another Study Wraps Up p
- Rrrr on the Phoenix Rising forums has been keeping us up-to-date on the Dr.
Felsenstein XMRV study at Massachusetts Gen. She reports that the study is
complete and written and is being shopped around for publication in a journal.
No word, of course, on the results.
- We are still waiting on publication of the Huber and Joliceur studies.
You can find a list of ongoing studies here.
About 24 studies are listed; six have not found XMRV, Dr. Alter did find XMRV
but the study has not been published. Hemispherx found XMRV using WPI labs.
Several Canadian studies not on the list may be underway as well.
July 2nd
- How Not to Find XMRV? - with conspiracy theories dancing in their heads, as the patient community reeled at the publication of the negative study and the
withdrawal from publication of the positive study, Dr. Vernon, Research Director of the CFIDS Association,
(and former CDC employee),
unleashed a lacerating attack on the CDC paper in an article called 'Blood From a Stone".
Pointing out that the types of tubes used to collect the
blood weren't suited for pathogen collection she said the study was 'designed not to detect XMRV'. Tiring of studies that
that do not attempt to replicate the WPI's 'exacting' techniques, she said problematic studies like the CDC study
Studies such as this one from Switzer, et al.,
"continue to absorb time, divert precious resources and fuel controversy instead of consensus." Check out an
analysis of the situation here.
- Today the WPI released a short statement noting, once again, that no research groups have yet attempted to
replicate the original study. After stating that the WPI had shared detailed knowledge of its techniques and positive samples
(which were not used in the final study), they noted the WPI is validating more sensitive assays for the virus which they will share
with other researchers.

I wrote.
- NatureNews Investigates 'Unnatural' Doings Behind the Alter Paper
- NatureNews provided more background information on why the
Alter paper was yanked. The Journals investigation confirmed the belief that DHHS officials were behind it. Additional
studies are reportedly underway to confirm/deny the original reports findings.
"Monroe (Stephen Monroe, director of the CDC's Division
of High-Consequence Pathogens and Pathology) called the delay a "strategic pause", initiated after CDC officials learned of a
contradictory study by the NIH and FDA team, reported at a meeting by NIH researcher Harvey Alter. Although a PNAS spokeswoman reportedly
told The Wall Street Journal that the study had been accepted for publication, press officers at PNAS refused to comment on the matter today.
One scientist familiar with the issue said that the journal's editor-in-chief, cell biologist Randy Schekman of the University of
California, Berkeley, sent the paper out for further review after government agencies
requested the publication delay. That review came back with requests for additional studies, the scientist says."
- XMRV on the Clock! - If you'll look to the left you'll see a clock counting the days from the publication of the
original XMRV paper. As of today it's been 252 days since the paper was published...and still no replication study.........
- Check out a nice overview of the situation here from the CFIDS Association
July 1st
- Outcry over Blocked Papers - Dr. Racaniello called the decision by the DHHS to withhold
two papers accepted for publication 'senseless' and charged that "they have compromised the entire peer reviewer process". He noted that
the decision would raise suspicions in the CFS community about their motives (which it certainly has)
- CDC Paper Released/Alter Paper Yanked-
Not long after that the CDC paper was released. The DHHS is going with the CDC results and put under question the Alter results by
allowing the publication of the CDC paper to go through while continuing to hold up the Alter report. The CFIDS Association
published Dr. Alter's statement that his paper has not (?) been accepted for publication and that his group is conducting further experiments.
"Our paper has not yet been accepted for publication. My colleagues and I are conducting additional experiments to ensure that
the data are accurate and complete. Our goal is not speed, but scientific accuracy".
That statement came a day after PNAS reported this "The paper was accepted for publication in the journal Proceedings of the National Academy of Sciences of the United States
of America but is on hold, according to Ashley Truxon, media coordinator for the journal."
DHHS clearly believes there are holes in the study - which
was not what we expected given the difficulty researchers have had, and are continuing to have, simply simply finding the virus.
The CDC paper found no evidence of XMRV in CFS patients or healthy controls.

"Altered Reality": Two Papers Disappear
(or How to
Conduct Science in the Dark - Amy Dockser Marcus at the Wall Street
Journal has become the go-to journalist for news on XMRV and CFS in the
national media. Now
she's broken the news
that the Alter study, soon to be published in the presitigous journal "The Proceedings of the National Academy
of Sciences of the United States of America", has now been withheld from publication. This followed reports that a negative study by the
CDC was yanked at the last minute from publication in another reputable journal 'Retrovirology". The papers were reportedly put on hold because
because 'senior public health officials' wanted to see either 'consensus' or simply a clear reason why the papers disagreed. Marcus called the move 'rare' and stated it
was causing 'a stir in the field'. IACFS/ME President Fred Friedberg called for the
immediate publication of both papers.
The path to publication is tricky.
There's the need to get money, usually lots of it, to start a study. If a researcher works in an institutional setting the resulting
paper may have to pass
review at that level. Then they have to meet the criteria for publication. Once that occurs a sigh of relief is undoubtedly given
because now the paper
is now on its own. The scientific community will poke and prode and shine a bright light on it and it
may fail but
at least it's out there...months or even years of research have a tangible result.
Except in this case. Dockser reported her science contacts stated it" is unusual for a paper to be held after it has already gone through the formal peer-review process
and been accepted for publication". The situation was unusual enough that neither the CDC, Dr. Alter
or FDA apparently even thought to
check with public health officials prior to submitting their papers for publication.
Fearing an embarrassing rift between two key agencies on an important health issue, public health officials, however, stepped in at the last minute
to ensure that neither paper saw the light of day until they could judge which one was correct - leaving researchers in the dark and
patients just plain aggravated.
Who wins/loses? The DHHS spares itself
the fate of having two departments posting diametrically opposed results. Who loses? The DHHS by playing the role of the heavy and
by getting egg on its face
by letting things get to this state. (If they were this concerned why was no one monitoring both efforts?) The
Research community loses, by not, at least at this point, having all the facts at their disposal - facts that could inform ongoing and
future research efforts. The CDC loses by giving
an already
untrusting CFS
Community on an opportunity on a gold platter not to trust them.
At the end it's astonishing - at least to this layman - how little resolution there is to the XMRV question 8 months after the publication of the
initial paper. The problem was reportedly not simply that the papers disagreed; it was that they disagreed in a manner which didn't
lend any clarity to the XMRV question; ie even after looking at them it is impossible to tell who was right and why....
Too many stones unturned? -
One wonders
if the CDC is giving full attention to the XMRV question. The agency pulled back on the DeFreitas virus in the 1990's when top officials determined that
they had better places to spend their money. If the CDC is getting bushwhacked by outside findings on XMRV one has to wonder if a similar cost benefit
analysis has caused the agency to leave some stones unturned in the race to understand XMRV.
Discuss it here.
June 28th
- The Dog Days of Summer - it was the calm after the little storm as the news on the startling Alter report died down...
Or did it? The lack of hard news breeds time for speculation so here's some nice
ripe speculation. The leaked Alter lecture followed hard on the disappearing act by the CDC
- and that was no accident....except that we got the events backwards.
The rumors about a negative CDC paper had been buzzing around for a couple of
weeks plus there was the
CDC's Press Conference/Press Release - whatever it was - that at least several sources said was on for that Monday.
That study was clearly on its way to publication but then suddenly the whole
disappeared in smoke. What happened? One guess is that the CDC, hearing about the FDA/NIH findings, pulled the paper at the last minute
Is this Really Rocket Science? Is this a plausible scenario?
In some ways it doesn't seem to be. It's hard to imagine how any laboratory with significant resources, could,
at this point in the game make such a major mistake. Let's put it this way; if the initial reports were correct then
the CDC's been all over this bug for almost eight months now; more than enough time to try every plausible
method of finding XMRV. One would think that THIS lab given the public interest in THIS pathogen would have
crossed all their i's and dotted their t's by now. This has nothing to do with chronic fatigue syndrome; it has everything to do with
a major lab being embarrassed by a major failure. Given that
it seems incredible that after 8 months of work they wouldn't know everything there is to know about how to
find or not to find XMRV. (Is this ROCKET Science?) One guess, if this scenario with the CDC turns out to
accurate.... is that the answer to finding XMRV is not going to be whether or
not the virus is cultured or not - that's too obvious; it's going to be a niggly little detail that no one at the
time thought mattered.
Slowing Things Down - Not Speeding Them Up - It's been
suggested to me that the Alter release could have the result of many pulling
back and rechecking their findings..which could mean less negative papers in the
short run and more positive papers in the long run. If Alter is right it's
possible that we many never, in fact, see another negative study again.....
-
Moving at Lightning Speed NIH Funds XMRV Grant! - Never count the NIH
out with CFS. In one fell stroke the NIH doubled the number of grants its
funded on XMRV this year with a grant to Rebecca Hanson at Cornell University in
Ithaca, New York. That's right, halfway through this year the NIH has managed to
match its total of last year (2), before all the ruckus broke out.
The Bell Grant? - This is a good grant, though, that could
have special implications for CFS. Dr. Hanson will be looking for XMRV in a
cohort of individuals from rural New York who became ill in 1985 - it's hard to
imagine that this is not Dr. Bell's pediatric cohort. It's a very nice study
that will look at a number of hot topics; they'll do repeat exercise testing and look for changes in
XMRV expression and protein production, pathogens, cytokines, nitric oxide, a growth factor and red blood cell changes.
They'll also be looking for variants of the virus. As the
author puts it: "We will investigate whether this retrovirus is both necessary and sufficient for the development of the illness,
or whether additional pathogens are involved. We will determine whether the
level of health and exercise intolerance in chronic fatigue syndrome is related
to particular virus variants, expression of viral proteins, and/or dysfunction
of the immune system." An important study, indeed!
CFS SEP sponsored - this study made it through the special
panel for CFS (SEP) (a rarity) and was actually funded by the National Institute
of Allergy and Infectious Diseases (NIAID) - one of the big missing players in
XMRV thus far. Its not a big grant as grants go - $270,000 - but it's quite an extensive project. It'wills due to end May, 2012.
The WPI has yet to get a grant funded. As more grants work their
way through the system we should see many more grants on XMRV and CFS from the
NIAID.

- The Mystery Study? -
Dr. Alter confirmed that a paper from the FDA and CDC is in the works but the big question now is
which study is it? Is this part of the big DHHS study the Health and Human Services Working Group is overseeing? Or is this
another study? At first blush it fits in well with the HHSWG study which contains NIH, CDC and FDA groups yet Dr. Mikovits, who is part of
the group overseeing the HHSWG effort, said it was not, to her knowledge, part of that effort.
Meanwhile, the link to the Dutch Press Release has now been removed from the WPI

National Media Begins Picking Up Alter XMRV Story - the story is finally
filtering down to the national media. On the Wall St Journal's Health Blog Amy
Dockser Marcus quoted Annette Whittemore saying that "It's what we've been
waiting for" although she cautioned that she wanted to see it 'in print".
Importantly an NIH spokesman confirmed the accuracy of the Atler presentation
slide while refusing to say more.
- WPI Posts Press
Release on Website - The WPI's Facebook Page yanked the Dutch Press
yesterday. Today the WPI website posted a link to the press release. We should
make clear that the two 'outlets' do not necessarily mirror each other or agree
with each other. The WPI website reflects the professional opinions of the
Whittemore Peterson Institute. The Facebook site is mostly run, to my
understanding, by Andrea and Annette Whittemore and the two sites may differ at
times. In the future I will make clear from which part of the WPI, website
or Facebook, the information is coming from.
-
Meanwhile Dr Deckoff-Jones Reports Progress - rather serendipitously Dr.
Deckoff-Jones reported that progress slowly continues on her and her daughters
now 15 week antiviral treatment trial. The cumulative progress for her
daughter appears to be pretty strong with her having enough energy to go out
socially and enjoy herself for four of the past five days
- a major achievement for many people with CFS. Dr. Deckoff-Jones also reports
she is not self-prescribing; that both she and her daughter are under the care
of another physician.
- Dutch XMRV Leak Reverberates - Patients leapt for joy at the news suggesting that the WPI's findings have been validated by two
major institutions in the US but not everybody was happy that the information had been released in a way it was.
The Whittemore Peterson Institute's Facebook page posted a link to Dr. Raccienllo's blog but refused to discuss the press release
otherwise, citing the need for a prepublication embargo of scientific findings. The CFID's Association didn't post
a link anywhere as they cited the same need. Both organizations either fund or produce research and need to
maintain strict standards regarding scientific mores.
ESME - an Alliance of European professional researchers, felt no such compunctions, immediately sending a link
out to all their subscribers and posting the
press release on their website. Neither the ME Association nor MERUK nor Invest in ME,
however, have reported on it nor does it appear that other news services have. It's
hard to imagine that the 'scoop' could imperil publication of an important paper but the episode does
underscore the antagonistic relationship between a press that wants to expose everything and a research
community for whom prepublication exposure can have dire consequences. Did the Dutch Journalists do us a
favor with their scoop?
-
Red Cross Report At the Zagreb Conference -
Roger Dodd, an official at the American Red Cross also gave a lecture on XMRV in
the Zagreb conference in late May. Some of his outline could presage a shift
that could occur in how CFS is viewed in the future. For instance, after noting
that CFS patients often have an acute infectious onset his outline states that
outbreaks in the disease do occur - a well accepted findings
amongst patients but something that's quite controversial in the traditional
research circles.
He also provided a list of infections that are putatively associated with CFS.
What was impressive about Dr. Dodd’s list was it’s size; it contained
enteroviruses, Epstein-Barr virus, cytomegalovirus, HHV-6 and 7, B-19
parvovirus, hepatitis C virus, HTLV (DeFrietas), spumavirus, Chlamydia
pneumoniae, Coxiella Burnetti, Brucella and Toxoplasma.
He also several times noted the involvement of CFS support groups and the
effects of patient advocacy going so far as to highlight a plea from what
appears to be a person with CFS that people with CFS be banned from giving blood
in the US.
Dr. Dodd's assessment of the different possible outcomes for XMRV ranged from it
being irrelevant (due to it being a contaminant) to a ‘Doomsday’scenario, at
least from the aspect of the Red Cross. In the Doomsday scenario,
researchers find that the virus
· does
indeed cause dread diseases such as CFS and cancer
· that
it has an extended incubation period; - this presumably refers to
its ability, like HIV, to apparently be present for a long period
of time before its effects are seen, making it difficult to easily spot an
infected person and stop the transmission
· that
it spreads rapidly
· that
it’s, in fact, already present in much of the population
In the Doomsday scenario the cat is either already out of the bag or very
difficult to keep in the bag because the virus spreads so easily and usually
undetectably. From an official standpoint this would make the virus difficult to
control..
He then noted that the Red Cross still needs much information; in particular, a
Gold Standard test that can reliably detect XMRV and information on rates of
prevalence in its donor population and determining what its risk factors are (ie
is it just found in CFS patients or people with other diseases,
healthy controls?).
The Blood Study : Then Dr. Dodd provides some information on
the National Heart Lung And Blood Institute (NHLBI) XMRV study . The study is
using whole blood and plasma to look for XMRV in 400 samples from Reno (BSRI?)
and 25 positive samples from the WPI and 25 controls. They are validating their
PCR results using antibody tests
Was the Past Prologue?- If this report proves true one can look back in hindsight and see evidence
that it was on its way given a uptick of positive reports over
the last month. Several weeks ago Dr. Klimas reported a positive paper was on the way; a finding a
Phoenix Rising Forum member reported was originally from Dr. Suzanne Vernon. Today, Hillary Johnson
reported in a blog that two researchers have contacted her in the last few weeks stating that a
major research paper confirming the Science paper will be published shortly and that it could push
positivity rates in ME/CFS even higher.
It’s possible that the recent AABB announcement recommending that blood collection groups aggressively discourage
blood donation by CFS patients, was prompted by these findings as well. Before the Fat Lady sings, however, about the
association between XMRV and CFS, we need to see
that research in print.

Dutch Journalists Report XMRV both NIH and FDA Confirm Science Study Findings (!) - In a startling
announcement two Dutch journalists from the Health Professionals Journal Ortho report that they were able to obtain a
lecture from NIH official Dr. Harvey Alter at the Blood Transfusion workshop May 26/27th in Zagreb, stating that
both the FDA and NIH had confirmed the WPI's original findings. Dr. Dr. Harvey Alter is
the Clinical Studies Chief at the Infectious Diseases and Immunogenetics
Section of the Department of Transfusion Medicine at the NIH Clinical Center in Bethesda. The Dutch Journalists report that
Alter's lecture stated "The data in the Lombardi, et al Science manuscript are extremely strong and likely true, despite the controversy".
The lecture also purportedly stated The association with CFS is very strong, but causality not proved. XMRV and related MLVs are in the donor supply with an early prevalence
estimate of 3%‐7%. We (FDA & NIH) have independently confirmed the Lombardi group findings."
The Dutch report does not include rate of XMRV prevalence found in CFS but does report that the 'association with CFS is 'very strong' which can only mean that
it was found in a much higher percentage of CFS patients and healthy controls. Indeed, given the fact that the FDA and NIH findings in
healthy controls are similar to those found by the WPI (4-7%) it's possible that prevalence rates in CFS were found to be similar the original findings (67%).
Dr. Alter is a well known researcher (he has a bio in Wikipedia) whose work lead to the discovery of the
hepatitis C virus. The chief of the infectious disease section and the associate director for research of the Department of Transfusion Medicine
at the Warren Grant Magnuson Clinical Center in the National Institutes of Health (NIH), he received the distinguished
Albert Lasker award in 2000. He has 300 citations to his name in PubMed.
Dr. Alter would if not confirm or deny the report but did say a paper would be
out soon.
It's hard to
imagine that such a report coming from such reputable scientists working in such
renowned institutions, would not quickly legitimize the original Science
findings. Researchers around the world (and governments and physicians and, of
course, patients) have been waiting for a definitive word on XMRV. If this
report is from the FDA and the NIH (somewhere in the NIH?) then this may be the
report that everyone's been waiting for. Because it's harder to find XMRV than
not find it any report that shows how to actually find it has the potential of
negating all the negative studies before it.
We have to be careful, though. Until these findings are in printed in black in white in a medical journal
they mean nothing to the research research. If the WPI's findings are confirmed an association with
CFS will be established. Then comes the work of finding if a virus is associated with any other diseases and what
role it plays in CFS. It could be a passenger virus or it could a major factor in CFS (ie the Puppet Master?). In any case the
confirmation of the WPI's original findings would, in itself, unleash alot of money and
activity towards XMRV and CFS.
June 18th
- AABB Takes Steps to Discourage CFS Patients From Giving Blood
in the US - the AABB (American Association of Blood Banks) recommended
today that CFS patients be discouraged from giving blood. This was expected
given that a few days ago, Dr. Katz
an executive vice president of the group, personally recommended that CFS
patients not give blood. The AABB did not state that CFS patients not be
allowed to give blood; that is apparently in the hands of the FDA, but they
recommended that blood collecting organizations provide a poster and a handout
that aggressively discourages people with CFS from giving blood. (The AABB is
not a small group; their membership includes 2,000 organizations spread across
80 countries. Creating and
distributing the materials to all the blood collection centers will obviously
cost a nice chunk of money)
The Whittemore Peterson Institute, the CFSAC
and the CFIDS Association of America all recommended recommended that CFS
patients be not allowed to give blood. (Both Dr. Klimas and the CAA had noted
that CFS patients with their low blood volumes shouldn't give blood anyway :)).
A survey by the CFIDS Association indicating that at least 6% of people with CFS
had donated since they became ill, undoubtedly helped AABB recognize the Blood Banks had a real problem. This move by the AABB brings
the US a least partly into sync with other moves by Australia, New Zealand and
Canada to eliminate the risk of cotaminating the blood supply with XMRV until
more is definitively known about its incidence in CFS.

XMRV Fact Sheet
- Anti-Retroviral Blogs
- Its been slow days for XMRV lately. Two blogs
purportedly by a doctor and by a research grad student that are decidedly
against the idea of trying antiretroviral drugs have appeared recently. The
doctor presumably represent view
similar to the 65% of health professionals in the Medscape poll that would not
use antiretrovirals at this point.
The Dr. - someone in the UK who says he sees a lot of CFS patients - believes
that only a minority of people with CFS have chronic viral infections that are
causing their disease. He noted that if XMRV is present then antiretrovirals are
indeed the suitable choice for treatment but only if the virus is actively
replicating and can be shown to cause the disorder. Right now all we can say
about XMRV replication is that, at least in the cells that have been tested thus
far, it appears to be very low. It's certainly possible that XMRV Is actively
replicating in some other cells someplace else in the body. Primate studies have
shown that upon infection XMRV moves through the body very quickly infecting
many different parts of the body. The WPI was able to find very low amounts of
XMRV In white blood cells and show that it was present in the blood but no one,
as yet, has even looked for it elsewhere. The WPI is reportedly doing that right
now. He's definitely right that taking antiretrovirals is something of a
crapshoot right now. What he mostly misses in the rest of his blog is
why people are taking that kind of a crapshoot right now.
The doctor
seems to get it about how desperate some people with CFS are at some points in
the article but then doesn't elsewhere. One point he states "What has been interesting to me is the
way in which patient groups have responded to the available research and information
about XMRV. Most appear to remain firmly wedded to the idea that it is the real deal,
and many ME/CFS forums are discussing research and treatment in great detail. Perhaps not mindful
of previous false hopes in this area of medicine, some are obtaining, at great expense, complex experimental
drug treatments via the Internet or from compliant doctors."
One wonders how else he would expect any patient group of a chronic and
often disabling disorder with few good treatment options to react? Repeatedly
citing the evidence of long-term damaging side effects
he strongly disapproves of Dr. Deckoffs treatment yet also states that short-term use of these drugs
is generally well tolerated. Yet he also ignores Dr. Deckoff's statements that she is engaged in short-term
trials of these drugs.
The Doctor also takes alarm at discussions on the Phoenix Rising Forums
about how to take these drugs yet discussions such as these are at the heart
of any public Forum; it's hard to see how they could not occur. After referring, really
rather snottily to 'all this foolishness' he does note that it does bring 'home one fact very clearly,
namely that CFS/ME patients are despairing for answers and solutions to their plight,
and will try almost anything.". It would be great if that
was the take home message people got from this blog.
If the doctor portrayed some of the snootiness one sometimes associates with the
British upper classes, at least he's polite. Polite is not something anyone
would ever accuse ERV of being. With a personality like a pit bull on steroids
(she has a picture of a pit bull on her blog) Erv could very well make Ty Cobb
look like a sweetheart. That doesn't mean she doesn't have her points at times,
however. In between her digs and put downs she, too, brings up the question of
viral load - noting interestingly that we have no idea what it is - we simply
know it hasn't been easy to find the virus. Viral load is one of the important
questions about XMRV and the use of antiretrovirals and our inability at this
point to quantify that is probably a real sticking point for those 65% of
health professionals on the Medscape poll. who are against trying
anti-retrovirals.
She also believes that, if you can't ojbectively
measure success there's no point in trying - an argument that resonates in some
parts of the research world but hardly would in patients. HIV
patients did have those diminished T helper cell levels to watch. CFS patients have NK cell problems (which, for some
reason are laughable to her) but their immune abnormalities do not appear, at least at this point, to
be associated with XMRV. Erv believes if you don't have a lab test to measure
then you shouldn't be trying a drug - as if the primary purpose of the drug was
to improve lab test results.
So how to measure antiretroviral efficacy in the
absence of a lab test? How about functionality? How about pain assessments? How
about putting an activity meter on each patient? How about those crazy RNase L
readings? These things can be done. Science can move forward without figuring
out all the answers first. In Erv's world researchers tie things up with a
pretty bow first; they take several years to quantify viral load and match XMRV
to an abnormal lab test and then they deign to try a couple of small treatment
trials. But given that some patients have been waiting for decades; it's no surprise that
some will gravitate towards antiretrovirals like a moth to a light.

Medscape Poll on Using Anti-Retrovirals in CFS
- what an interesting poll this is; first it's
kind of amazing that it exists at all - the medical community is pondering whether its appropriate to try anti-retrovirals
before a) the XMRV finding has been validated by another laboratory and b) before it's been definitively proven to play a major
factor in CFS.
Even more surprising are the results; I would have have thought the overwhelming response from this conservative community
would have
been that, under no circumstances, its it acceptable to use these drugs at this point. Its true that 68% of the respondents voted that way
but 32% of the respondents did not; they felt it was either
appropriate to do that or they weren't sure. I think this poll indirectly highlights the fact that a nice chunck of physicians do have
a sense of how serious a disorder CFS is, and they are open to options that they wouldn't have been open to earlier.

- Dr. Enlander Proposes Large Multi-Lab study
- We've all heard
about the need to for different labs to look at the same samples. Now Dr. Enlander is proposing
a large double blinded multi-lab study that he believes will tell us whether the problem is in the
different methodologies or the different patients. There is no breakthru in laboratory procedures here; this is
simply a chance for a number of CFS labs to test exactly the same patients and see where
they disagree or agree. Dr. Enlander would be coordinating the study. It would take about $10,000 on his side to
bring it off.
Proposal to test the presence or absence of XMRV virus in the CFS in a double-blind trial using replicant patient specimens in five different labs.
Preamble
The presence of XMRV virus in that CFS patients was reported in the Science in October 2009. This caused great excitement in the scientific world, as an infective organism was suggested as the etiology of CFS. The excitement abated as other labs attempted to replicate the result. Papers were soon published denying the presence of the XMRV virus in the CFS patients. Discussion then opened with various researchers debating the possibility of poor storage of specimens, poor selection of CFS patients without proper criteria, different methodology in the determining the presence of the virus, and other aspects in the research methods. Patients and physicians were then left in a quandary whether the original research gave us insight into a viral etiology. Indeed the picture became more blurred.
We will attempt to determine whether testing methods or patient selection were different or faulty. We propose to replicate a study in the five labs that were prominent in the disputed discussion, by replicating patient and control specimens in divided aliquots in a double-blind trial.
Method
100 patients , who have been diagnosed by the Fukuda and Canadian criteria for CFS, and 100 matched controls will have 15 ML blood drawn (two vials) . The 15 ML blood specimens will be combined into a single tube and will be centrifuged . The supernatants will be refrigerated. Each patient or control specimen will be numbered randomly and blindly 1 to 200, each specimen will then be divided into five aliquots and labeled A,B,C,D and E . We will thus have 1000 test aliquots to be divided between five viral test labs.
We will send 200 aliquots in frozen containers to five virus testing laboratories; A) Whitmore Peterson Institute in Reno Nevada, B) Jonathan Kerr in London, C) Simon Wessley group in London, D) Gow in Glasgow, and E) de MeirLeir in Brussels
The selection of these labs does not mean that we recommend their methods. These labs have not replicated the original thesis. Perhaps, the comparison of duplicate specimens in a double blind trial can be revealing.
Results
The test results will be sent to Dr. Enlander in New York, where the blind will be opened and the results tabulated. As each lab has received the same patient and control aliquots, we can attempt to correlate differences in testing method without the problem of bias in patient selection.

- Dr. Komaroff on XMRV - Dr. Komaroff was one the first researchers to recognize
chronic fatigue syndrome as a legitimate disorder in the early 1980's. A Harvard professor, he's been invaluable spokesman
for us for many years. While
his peers, at least at first, must of thought of him as a wild-eyed radical for his support of CFS, within the CFS field itself Dr. Komaroff is thought of as a careful, moderate analyst.
A very respected figure he traditionally winds up the International Conferences
with his take on where the field is now. So what does
this longterm CFS spokesman think of XMRV?if
During his hour-long talk at the Massachusetts CFIDS Association
(available on video) in late April Dr. Komaroff spent a good deal of time working his way
through the many other exciting aspects of CFS research before he got to XMRV.
When he finally did so he noted how prestigious the Science journal is and the
overlapping layers of evidence they demanded the WPI present before they would
publish the paper. (Seeing the
signicance values - which are statistical approximations of the likelihood that the results were due to chance - was
eye-opening; statistically these were very strong findings.) After noting that he himself had never written a 'perfect' paper, Dr.
ifKomaroff noted that the sample sizes for three of the backup tests were fairly small. Regarding the negative studies he would
have nothing to do with the idea that the researchers were incompetent - calling them very skilled
researchers - but he did note that there was one problem in all of the studies that
could have caused them to miss XMRV altogether. Whether he was referring to a
different problem in each study or to each study's decision not to culture
the virus was unclear. It
was clear that he felt none of the studies had closed the door on XMRV.
Dr. Komaroff's most interesting comment from me regarded his 'need' for XMRV to turn out. He noted that as a longtime
advocate for CFS patients and as a physician, there is a part of him that's always yearned for a simple answer to the disorder but he's never believed that CFS is going to be that simple. He believes
ME/CFS is a multi-systemic disorder in which pathogens play a major role but that
he would be surprised if one pathogen was the 'puppet master' so to speak. He
sees XMRV's role as a co-facter - perhaps a pathogen that works in concert with other pathogens
to cause the symptoms of the disorder.
It was intriguing and
uplifting to see how optimistic he was irregardless of how XMRV turns out. He
noted how much has changed since he was one of the lone figures fighting for CFS
patients, and what a different attitude his peers have towards CFS now; in
particular, he remarked on how few of them think of it as a psychological
disorder - and he believes more change is in store. In fact, he believes that
the next two years will bring another sea change in how the medical community
relates to ME/CFS and that we're in store for quite a bit of progress.

- Dr. Deckoff Responds - the
Chicago Tribune article yesterday came down strongly
against the idea of CFS patients trying strong antiretrovirals before XMRV has been proven to
cause ME/CFS. Dr. Decker, of course, has been very public about her belief that it's appropriate
and mostly safe for very ill patients to try these drugs. She quickly responded to
the article in her blog.
She stated that there is little risk from short-term use of these drugs, that common lab tests
are sufficient to monitor patients and that patients today typically take far lower doses
then in the early days of AIDS when many of the horrendous side effects were noted.
Dr. Deckoff questioned how much different the 'horrible death' AIDS patients
would experience without these drugs is from the 'horrible life' some CFS patients experience. She referred to
the large body of knowledge that's been built up around AZT and other retrovirals if
and the fact that her daughter has
has experienced no ill effects after 3 months on the drugs.
She also noted the many CFS patients commonly experience
deleterious side effects from psychotropic and other drugs that have little chance of significantly helping them. In short,
she felt the
risks are acceptable given the short term nature of the typical patients regime and their ability to
remove themselves from it at any time. She also talked about the autism/XMRV
connection. There's much more in her blog - check it out here.

Dr. Deckoff Reports
- Dr. Deckoff continues to report on her and her
daughters anti-retroviral treatment trial. Since starting treatment 3 months ago her
she reports that her daughter is more stable. Adding Tenofovir lead to a
noticeable improvement. At some point she stopped
long-term antibiotics and she started Actos shortly before the anti-retrovirals,
so she's had alot of treatment changes over the past couple of months.
Dr. Deckoff started Tenofovir at a low dose two weeks ago and is up to full strength with it now. She
reports much improved cardiac and GI symptoms. She does note that she had been improving
since she discontinued Lyme treatment 10 months ago. (Check out her very interesting blog
on what she believes are the dangers of some Lyme protocols). Neither of them perfect test
cases because of the other strong therapies they were either on or had recently stopped but as the
trial proceeds we'll know more and more about the specific effects of the retroviral drugs. For now
both report improvement and both still have a long way to go.

Harsh Chicago Tribune Article
- An article on the front page of the Chicago
Tribune called "Hope Outrunning Science" paints Dr. Mikovits in a rather
negative light.
-
Another XMRV Study - XMRV studies appear to be popping up everywhere. This
is one we missed. George on the Forums found a call for Ph.d students to
participate in a study on the role amyloids play in XMRV transmission in the
semen. Amyloids are interesting because some preliminary evidence suggests that
amyloids in the brain may be a factor in CFS. The semen is a long way from the
brain and there isn't much evidence of sexual transmission in CFS so its not
clear how it could be a factor. In any case, the study does indicate the
wide-ranging level of interest in this pathogen.
-
XMRV Confidence Poll - where are the Phoenix Rising forum members on XMRV's
chances right now? Probably not as confident as six months ago but still very
hopeful. Of 104 votes about 22% are sure that XMRV is a major cause of CFS, 55%
believe there's a good chance that that's true but need more evidence, 9%
believe it's possible but are skeptical at this point, 14% believe XMRV is
probably a co-factor and only 1% don't believe it plays any role at all.

- Dr. Vernon Talks -
Dr. Vernon of the CFIDS Association made XMRV a central feature in her monthly
article for the CFIDS Association. First she noted the many viruses that have
been implicated in chronic fatigue syndrome, and after making a call for more
research in those areas, paused....and said now we have XMRV - a very different
situation, indeed. Emphasizing that the XMRV finding has to be validated first
she pointed to brighter days ahead for ME/CFS if that occurs stating that its validation would make CFS a source of
'intense' funding" - something hard to conceive of a year ago. The potential power of the XMRV finding
is enormous; it has the potential to
re-orient the research communities approach to an entire disease and make it, for the first time in 30 years, an
'intense'
area of funding.
She also explored the possibility that XMRV could be part of our 'metagenome'; ie. one of the thousands of
living organisms that we generally, but not always, co-exist with just fine. This idea came from the findings that
XMRV is present in some healthy controls and at least one other disease state. This suggests that XMRV could be
present but generally bottled up in most healthy people, but like other viruses we know about, has somehow escaped its
bounds in CFS and is wreaking havoc. She noted that precise process happens in autoimmune disorders, cancer, chronic inflammation and could very well
may be happening in CFS as well.
- CFS Patients Knock Out Two Study Coordinators in One Week! -
not long after the details of two studies; one in California and one in Canada
were published here and on the Forums we were met with calls to please turn off
the spigot and remove the posts (which we did) because the study
coordinators were being deluged! Such is the interest in XMRV....
- Dr. Silverman Publishes
- Dr. Silverman of the Cleveland Clinic was one of the co-authors of the
Science paper in Oct. He's a very well respected researcher and he's just
published a review of what we know about XMRV in CFS and prostate
cancer. Unfortunately all we don't have the full paper but we do the abstract and Dr. Raccinello's take on it.
Dr. Silverman posits four reasons why
the four studies since the Oct paper have failed to find the bug. We've heard them all before.
Contamination from mouse droppings - which he
discounts because separate labs using different techniques have found XMRV.
Different genetic sequences in different countries
make it hard to find XMRV. (This doesn't seem
likely; the WPI reported that 2/7 samples from the Kuppeveld were
positive for XMRV; ie they can find it in Holland). Differences in the geographic spread of the
virus - ie, its not in Europe (or Canada or parts of the US?). (This doesn't seem
likely either - given the WPI's ability to find XMRV in the Kuppeveld samples
and Dr. Huber's and Dr. Joliceuru's inability to find XMRV in US ot Canadian
samples). Only the last reason - that
the research community is really not
sure how to look for XMRV really holds allure (
"here are no standardized, sensitive methods of detection, and no widely
available positive control samples."if) .
(Note that he doesn't seem to be worrying about cohorts - presumably too many
patients have been tested for that to be a real concern any more.) if
But why no widely available positive samples for XMRV to test against? The WPI furnished positive samples to the Kuppeveld and Huber teams (reportedly
19 of them to Huber). They have stated they're willing to provide them; why other teams don't have those samples is unclear.

it upon himself to actually ask the CDC if they were going to have a press
conference and the answer was:
There are no plans for a news release from the CDC or a CDC sponsored
press conference on the subject of XMRV. There is a paper authored by an
official from the CDC under consideration for external publication but the
details of such publication would be released/announced by that publication and
not the CDC. Hope this helps, but that is all there is at this time. Regards..

Regarding her letter Andrea explained
I
wrote it last night thinking in case I wasn't well enough to attend . I just was
very very short in stating 17,000,000 suffer from ME/CFS from around the world .
Then I stated we only get 3,000,000 dollars to reasearch this disease from our
government. This must change I also asked her to please look into XMRV and find
out the implications involved. I thanked her for coming and hoped Reno would be
the host I know she can be :)
Expect the Obama's to be coming to Nevada frequently
as they support Sen. Harry Reid (and CFS advocate) in his tough fight for reelection.
- The Canadian XMRV studies - Meanwhile Canada is definitely doing its part to figure out
what XMRV is doing in ME/CFS. Dr. Joliceur, a well respected researcher jumped
in very early; his study is complete and it did not turn up any XMRV.
Unfortunately we don't know anything about the methods used.
Dr. Lorne Tyrrell,
a well known backer of CFS patients in Canada, and the leader of the
La Ka Shing
Institute of Virology in Edmonton, is starting what looks like a quite
comprehensive study. In consultation with the WPI, CDC and NIH Dr. Tyrell is
examing cytokines, RNase L and XMRV. (This study suggests that despite the
string of negative studies, XMRV is far from being a dead topic at the CDC or
NIH.) The study will start this summer.
Check out the study details here.

this)
Dr. Tyrrell: DaisyMae on the Forums provided this information on Dr. Tyrrell:
He is the Chair, Institute of Health Economics and Professor and CIHR/ GSK Chair in Virology, University of Alberta
Dr. Lorne Tyrrell is the Chair of the Board, Institute of Health Economics. He is the CIHR/GlaxoSmithKline Chair in Virology at the University of Alberta and the CEO of ViRexx, a biotechnology company in Edmonton. Dr. Tyrrell is also the Chair of the Board of the Alberta Health Quality Council and a member of the Medical Advisory Committee of the Gairdner Foundation and of the Research Council of the Canadian Institute of Academic Research. In 2004, Dr. Tyrrell completed 10 years as the Dean of the Faculty of Medicine and Dentistry at the University of Alberta.
A medical specialist in internal medicine and infectious diseases, Dr. Tyrrell began working with Dr. Morris Robins in 1986 on a system to identify potent antivirals against hepatitis B virus (HBV) which infects about 400 million people worldwide. Through their work they discovered several potent antivirals against HBV and this resulted in a major collaboration with Glaxo Canada (now GlaxoSmithKline).
The collaboration led to the discovery that lamivudine had potent antiviral activity for HBV and today lamivudine is licensed worldwide as the first oral antiviral for the treatment of HBV infections. Lamivudine has been shown to decrease the development of cirrhosis or liver cancer in chronic HBV carriers. This work also reopened the option for resuming liver transplantation in patients with end-stage liver disease from HBV. More recently Dr. Tyrrell collaborated with Drs. D. Mercer and N. Kneteman to develop the first small animal model to support HCV replication.
Dr. Tyrrell has won numerous awards at the University of Alberta (Rutherford Undergraduate Teaching Award, J. Gordin Kaplan Research Awards, and the University Cup). He won the ASTech Award for Research in 1993 and the Gold Medal of the Canadian Liver Foundation in 2000.
Dr. Tyrrell was appointed to the Alberta Order of Excellence in 2000, an Officer of the Order of Canada in 2002, and a Fellow of the Royal Society of Canada in 2004. He was recently awarded the F.N.G. Starr Award from the Canadian Medical Association in 2004, and the Principal Award of the Manning Foundation in 2005 for his work on the development of oral antivirals for the treatment of HBV.
Dr. Eleanor Stein, a ME/CFS physician (who actually has ME/CFS) is reportedly
engaged in another study. Dr. Stein has provided patients for past Canadian ME/CFS research efforts.
June 1st
- CDC Skunks Out? We have it from a good source that the
CDC was, indeed, going to make a 'major announcement' on XMRV today but that it
has been postponed. They're starting to look like the gang that couldn't shoot
straight.
-
VIP Dx
Announcement - Meanwhile, VIP Dx went ahead and did make their major announcement. The
long-awaited antibody test will be available within 30 days. The director of
Marketing And Client Relations for VIP Dx stated that “This serological test will allow our lab to
quickly and accurately determine which individuals are positive for XMRV. Discovering who is positive is an important
first step in helping to determine how XMRV is impacting human health”.
That is certainly true; antibody tests are the cheapest and most common way of detecting pathogens. Since they
are detecting immune agents produced in response to an infection (the antibodies produced by B-cells)
they can't be picking up byproducts of contamination - as a PCR test
could. The only question marks about antibody tests,
so far as I can tell, are a) their ability sometimes to pick up the presence other pathogens and b) their lack
of accuracy in patients whose immune systems have been so depleted that they're not producing antibodies.
The WPI
has been working on this antibody test for some time now and presumably would not release
a test that
was not specific for XMRV only. With regards the second question, it's not clear how many CFS patients are
that immune depleted.
In any case, the new antibody test should result in quicker, cheaper and more accurate testing for
the vast majority of patients and help considerably on the research end.
Several other antibody tests are being developed. Dr. Singh at ARUP at the
University of Utah, John Hackett at Abbott Labs, John Petros at Emory University
and Dr. Ruscetti at the National Cancer Institute are all reportedly treating
antibody tests as well.
VIP Dx Becomes Unevex - VIP Dx has now been
acquired by the WPI and the WPI Center opens at the University of Nevada VIP Dx (now Unevx) will be housed within it and become, with
WPI, a part of the University of Nevada system. In effect it will be a speciality University Lab for the WPI. This is a major step; it means a
CFS lab will be on the premises offering, presumably, as low cost tests as possible. With Unevx on board the WPI can develop tests,
study them in a research environment and quickly make them available. The lab
will play an important role in the 'translational medicine' ie; quickly turning
research advances into treatments the WPI facility espouses to. One has to assume this move was in the works
but its a relief that it happened.
It certainly points to the strong support the University of Nevada has for its
Whittemore Peterson Institute.
A Clarification on Ownership - I have been informed that the Whittemore's never owned VIP Dx as was reported;
instead prior to the sale the lab was owned by
its shareholders and Annette Whittemore's
small number of shares were held in trust for the benefit of the WPI. My
understanding is that the Whittemore's provided substantial financial
assistance to the lab years ago because it was the sole source of RNase L and
other speciality tests in the United States. In any case with the opening
of the WPI facility in August, the Unevx Labs will be firmly ensconced within
the University system.
A European Lab...Finally - RED Labs in Belgium will begin offering XMRV tests - finally providing European CFS
patients with a testing option. VIP Dx's website is still bouncing on and off
the internet.

May 31st
- Has It Begun?
- the VIPDx website is partially up: the crazy ads are gone, the normal website
front is up but most of the tabs are gone - it appears they're in the process of
doing some heavy web reconstruction. The big news, though, is that the website
now states "VIP Dx will make a major announcement on Tuesday, June 1st".
One has the feeling it's not going to be on the next test for HHV6....Will this
news coincide with the publication of the CDC press release and study? Has the
'Big News' begun? Something major has happened
at VIP Dx . We'll know what tomorrow!
- XMRV Confidence Poll:
You've heard of the consumer confidence poll that tracks
consumer confidence in the economy. Now, as we start off on what could be a big week for XMRV, take the
XMRV Confidence Poll; this poll asks what role do you guess XMRV plays in ME/CFS?
Check it out here
- XMRV Prevalence and Definition Poll - How much of a factor do you think definition
will play a role in who tests positive for XMRV? Will XMRV show up in spades in
the Canadian definition and bomb in the Oxford? Let us know in the
XMRV Prevalence and Definition Poll.
May 30th
- The Struggles of VIPDx
- VIPDx is the only lab licensed by the WPI to do the XMRV tests. The VIP Dx
website was down for almost a month earlier in the year and, if I understood
correctly, has been down for some time now. Actually down would be an
improvement as the website currently shows the VIP Dx logo but is simply filled
with Google Ads. Retooling a website to accomodate new testing is one thing -
allowing your web presence to be overtaken by Google Ads is quite another. A
message on the site states that the domain is not attached to an active website.
Maintaining a presence on the web is obviously critical for a business and it's
not a difficult thing to do and it's hard not to conclude that something has
gone quite wrong at VIP Dx labs.
- Anti-retroviral Treatment Trials on Phoenix Rising - Several more Forum
participants are reporting on their anti-retroviral treatment trials.
CFS Since
1993 has been on them for two months now. He reports he felt a little better at
first but is back to where he was.
JimBob just started Raltegavir three days ago - and he will keep us up to date.
LadyBugMundy started antiretrovirals a couple of months ago and has stopped reporting on her experiences with them.
- Hemispherx, the maker of Ampligen, reported on XMRV results presumably from VIP
Dx from patients taking
Ampligen. You can
access the webcast for another couple of weeks here. He reported
"We've looked so far at several hundred specimens using a prespecified research plan. We can say based on the interim report, (we're still looking to do several hundred more samples) that the initial results indicate two things;
1) about two thirds of people with chronic fatige syndrome do have a very serious retrovirus, which is infectious, and which can only be found in a small percentage of normal people, but can be seen in people with hereditary prostatic cancer.
2)But the second and really exciting function here is that the patients who recieved ampligen and also had the novel retrovirus had a very dramatic benefit greater than that of patients who received ampligen and did not have this virus.
It's a tentative finding and as I said the study is ongoing, but as I said it does involve hundreds of subjects studied on a blinded basis in a predetermined research plan. We believe that we've tentatively identified a subset of patients
who are obviously in harms way. We know this because the incidence of suicide, cancer and sudden catastrophic cardiovascular events is very high in this population generally. Some of these events may be due to this virus, and those patients have a disproportional therapeutic response to ampligen versus patients on ampligen without the virus and versus placebo patients.
So we hope within the next several months to finish up on this analysis and to meet with the FDA to lay out a clinical plan for confirmatory study."
It's a very interesting finding. Hemispherx is hardly trusted by many but they
do report they are looking at hundreds of patients, and that the 'study' is
'blinded in a predetermined research plan" (?). VIP Dx is reporting XMRV is
present in 2/3rds of this presumably quite sick population and that people who
were XMRV positive and were taking Ampligen were doing much better than people
who were XMRV negative. Ampligen is an immunomodulator - not a anti-retroviral -
and Hemispherx has been accused of promising too much for this drug in the past
but it's clearly very effective in some patients. Why it would do better in XMRV
positive patients is a puzzler, for sure.
Dr. Carter's statement
that we've 'tentatively identified a subset of patients who are obviously in
harms way is intriguing since it suggests that they're looking at a potential
biomarker for illness severity. He also suggested that severely ill XMRV
positive patients do disproportionately better on Ampligen than anyone else-
which would be a blessing since this is the hardest group to help. However we
don't have any numbers - we don't know how much better they are doing (are they
1/2 way to well? 2/3rds? 1/5th?) He said it would take several months of analysis to get the numbers out.
This was Dr. Carter speaking to investors not the scientific community.
- Wiping XMRV Out! (of the Blood Supply) - WPI and Cerus confirmed that the
Cerus pathogen inactivation system called Intercept does inactivate XMRV in
blood - thus potentially providing a way to remove it from the blood supply. The
Intercept system uses ultraviolet light and chemicals. While it is not approved
in the US it is approved in some countries in Europe, the Mideast and in Russia.
There are concerns about the chemicals used in the US.
A 2003 trial resulted in the Intercept system being rejected because of
slight respiratory problems- a problem Cerus says has not shown up elsewhere. It
does not appear that Cerus is close to making it to market in the US at this
point.
May 28th
- Dr. Mikovits is continuing to rack up her frequent flyer miles. She'll be at the
AutismOne conference on Sat talking on XMRV from 3-4 pm CST. They are streaming live some talks (its a huge conference) but it
doesn't appear, at this point, that hers will be one of them.
May 27th
- Dr. Huber / Dr. Mikovits Clash - Chris came
down hard on Dr. Huber in his blog but there are different viewpoints out there.
Several people have pointed out to me that some of Dr. Mikovits comments about
the negative studies questioning the ability or even desire of other
retrovirologists to find the virus have created considerable frustration amongst
some researchers and he
wondered if that played a part in their little 'clash'. We saw this in Dr.
Racciniello's talk with Dr. Goff when felt that some of Dr. Mikovits
comments suggested that she thought that the rest of the research community 'doesn't know how
to do PCR'.
Another person who met with Dr. Huber found
her to be a bright, friendly woman who had initially been very excited to find a
link between XMRV and the endogenous retroviruses she's been studying. Another
person noted that this is the second group to be able to find XMRV in samples
sent to them from the WPI but not in their own samples. There are a number of
possible explanations for that, one of which is XMRV is somehow getting into the
WPI samples but is not present in CFS patients at large. It's also possible
that there was some problem on the researchers end.
Given the problems with the
PCR studies the ability
to find antibodies to XMRV - which we know that Dr. Singh and others are looking
for - will be key factor. We do believe that some of the more
comprehensive studies will be coming out soon. That CDC paper has not come out
this week as expected - now we hear that a Press Release is being written and it
will come out next week.
May 26th
- The Patient Advocate on the XMRV News from the Invest in ME Conference -
Chris, the Patient Advocate, reported on the Invest in ME Conference, as he does for many.
The conference was a good one but Chris felt Dr. Huber went too far when she decided,
apparently at the last minute, to report the negative results of her XMRV study. Here's
Chris's take on what occurred:
"Towards the end of the day, things heated up a bit. Brigitte
Huber gave
a talk on her HERV-K18 research and then added a coda on XMRV. She did an
unexpected and gratuitous job of sandbagging Judy Mikovits, who was the next
speaker. Huber methodically went through her recent XMRV “study”, explaining in
her officious voice that her PCR test was the “assay of choice” and “very
sensitive”. She tested 228 samples, 112 from Susan Levine, 105 from Taylor in
Chicago, and 11 from the HHV6 foundation. Then she put up a slide with red
letters that said, “All samples were negative for XMRV integrase”.
Huber said, “We cannot see in our patients XMRV like in the Science
article”. In a further confounding maneuver she hinted or charged that the WPI
study was “contaminated”. This charge needs to be challenged, as it is a lie. As
she was leaving the lectern Huber said in a wonderfully disingenuous voice (to
no one special, but I suppose it was directed towards Judy Mikovits), “Sorry”.
It was a revealing and weasily moment.
To me it is becoming obvious that certain people, especially doctors who
have been treating patients unsuccessfully for years with half-baked treatments,
or researchers who are connected to the academic research money tit, are trying
to sink Mikovits and the WPI. This is not science; this is venality. This
negative reaction has little to do with whether XMRV has any validity or not.
That is a separate issue and there are two sides to the argument; and it needs
to be fought out according to established scientific methods. I think that
certain critics sense, perhaps correctly, that soon they might be out of a job.
The day before the conference, there was a brain storming session with the
various participants at this conference – Cheney, Chia, Huber, Jason,
Whittemore, Chapman. It is a great idea and discussion/disagreement (sometimes
fierce) is often a necessary and useful result of such exchanges. In this
afternoon session, Huber launched an attack on Mikovits.Mikovits did her usual job of
defending herself. Huber left the group early (maybe to go shopping?). As she
left Huber promised that she would not create a controversy by revealing her
study results the next day.
Overnight Huber changed her mind, honest soul that she is, and made her
awkward revelation. It was all quite unseemly, and did not fit the tone and
tenor of this conference – which is heavily ladened with sick patients, hanging
on by a thread. They make a great sacrifice to get to this conference, but not
to hear this kind of shit. After all this is really not a scientific conference,
and this nice bit of spite was entirely out of place.
When was the last time that Huber gave one iota of thought about CFS
patients? I can tell you exactly – it was… Never!
I watched this with fascination, realizing that Huber in her righteousness
had put her head on a block and asked to have her face kicked in. It was a great
setup, a “once in a lifetime situation”, and Mikovits came through big-time,
doing what she needed to do. She remained calm (inside she must have been
boiling) and delivered a splendid lecture (the best that I have seen her do) and
demolishing Huber. The effect was that Huber shrank down to the size of a pea. I
had talked to Mikovits the day before about Huber and advised her in general to
disregard her critics and just roll over this woman (not that Mikovits spends
one moment listening to me). Some critics need to be rolled and this was just
what happened. At the end of her lecture, Mikovits got a loud and sustained
applause showing deeply felt appreciation.
"
Chris also reported that the WPI was moving forward on all cylinders
"I observed several individuals from the
WPI doing
their presentations and establishing connections. I can assure you that the
announcement of the demise of the WPI is premature. They are moving faster than
ever. The WPI is on a trajectory that will leave its critics in the dust. While
others quibble over this and that, and lay traps to distract them, the WPI are
putting all that aside and focusing on the task at hand. More specific and
accurate testing is close at hand, as is means to track improvement in patient’s
immune status, as well as clinical trials using various existing anti-retroviral
drugs. Peptide T is still in the picture. (Another non-WPI source indicates that
GCMAF might be a player.) (Time will tell in all this and the nay-sayers have
put great effort into trying to cut off the funding and grants for the WPI. In
this they have been somewhat successful, leaving it to the rest of us to do what
we can to increase funding for this important scientific research.)
The WPI is in the process of projecting and clarifying their mission and of
making collaborative connections with the international community in a manner
that has never been seen before in this disease."

-
Dr. Peterson in Madrid
- Dr. Peterson was reportedly at the Invest in ME conference but didn't speak
but did hold a question and answer session in a conference in Madrid (These
jetsetting researchers :)) Thanks to the wonders of technology a video is already available
and more are to come apparently. A
person stated that he knew of some HIV patients with XM RV who were not
improving on antiretrovirals (?) which made him think that XM RV was a passenger
virus. Apparently Dr. Peterson has HIV patients with XM RV as well and he asked
him about them. Dr. Peterson acknowledged that XM RV could, of course, be a
passenger virus - he said that's an area they need to do more work on - but also
that that scenario simply could imply that the patient is not getting the right
anti-XMRV drugs.
On a question regarding the negative Huber study Dr. Peterson noted that Dr.
Huber used a probe for an enzyme XMRV produces called XMRV integrase and failed
to find it. Dr. Peterson said the question was how accurate was the probe
(key question) and what kinds of patients she tested (not a key question). Dr.
Huber measured somewhere around 200 patients from Dr. Levine - a well known CFS
physician in New York and - and Dr. Taylor, who is studying adolescent ME/CFS
patients plus some samples from the HVV6 Fdtn. If this is a cohort problem then
it's hard to see how XMRV's going to make a big difference in the ME/CFS
Community; these are pretty solid ME/CFS patients. It seems much more likely
given the WPI's continuing findings of high rates of XMRV prevalence that the
differences lie in the methodology. He brought up the very interesting
point, though, that Dr. Huber was able to find XMRV in a sample they provided
her but not in any of her patients. That could suggest a she had a different set
of patients - but if XMRV is only found in WPI samples then one can see why she
would begin to speculate about contamination - as she did at the Conference.
May 24th
- Heating Up in London - Things apparently got hot in London at
the Invest in ME Conference and it wasn't the volcano that was smoking. The
Conference was packed with important speakers from Jonathan Kerr to Paul Cheney
to Judy Mikovits. Two presentations by Dr. Chapman and Dr.
Chai were on one of those 'other' viruses (enteroviruses).
Huber XMRV Study is Negative - Things apparently got a little
hot when Dr. Huber presented negative findings from her XMRV study. It was a
pretty large one - 228 patients from Dr. Levine and Dr. Taylor in the US and a
few from the HHV-6 foundation. She believes apparently believes that she's found
a source of contamination in a reagent; that would be tough news for the WPI
since it would be an unsuspected source; ie it's not an area they apparently would have thought to search.
Dr. Mikovits has always said,on the other hand, and Dr. Coffin
has backed her up, that contamination in a slide
cannot produce an antibody response in the body. Antibodies are created in the body in response to viruses. If you
contaminate a sample it's hard to see how that's going to produce antibodies. That
has been the crux of the
argument for the WPI.
Dr. Mikovits reportedly got a standing ovation. Dr. Peterson was there but didn't speak; he'll
apparently be speaking in Oslo on XMRV in the next couple of weeks.
We heard there was going to be a negative study coming out soon; apparently the Huber study was it. We also
heard there was going to be a positive study coming out soon as well - could that be the CDC study? That would be
a shocker given their history but who knows.
For more of the discussion
- Dr. Klimas Talks on XMRV - ME/CFS Knowledge Center has a great talk by Nancy Klimas on
ME/CFS research. Dr. Klimas was one of the most excited researchers when XMRV
came out; she's an immunologist - she sees all these signs of immune activation
and XMRV fit really well into what she's seen in ME/CFS. Now seven months later,
with 3 negative papers behind her what did she say?
First off she said both a negative and a
confirmatory study are coming out. She's not discouraged about the negative
papers or even particularly surprised; until the validated methods for finding
XMRV have been ascertained she appeared to feel that they're kind of a logical
outcome of the process. Meanwhile she is engaged in a four-site study using her
samples and the results were almost
amusing to hear. She sent out samples to four different labs -
all of which said
they could find XMRV - and they all gave her different results! (Mein Gott!)
Clearly we can know nothing until we have a test that everybody agrees is
correct.
In her studies she's looking for the virus in every way possible; PCR, antibody,
culture and ...one last way that escapes me. She didn't necessarily pooh-pooh
the early studies but she did note that they are only looking for the virus in one
way; the WPI looked for it four ways - and that's what she's trying to do'
She did note that the pharmaceutical companies have been digging into this virus and they basically know
what compounds might work against it - they're just waiting for confirmation that it is there and the
trials will start (!). That's great news if and when the WPI's findings are confirmed.
A Rising Tide - A rising tide floats all boats and the XMRV finding appears to be sparking more interest in
CFS across-the-board. Dr. Klimas noted that the NIH review committee she sits on had double the number of CFS applications that it usually
does in January and considerably more in June; that's great news for CFS no matter how XMRV turns
out; increasing
researcher interest has been absolutely one of our key needs and it appears to be happening.
Check out the video here.
May 22nd
- Granting XMRV - We've been focused on studies but there's
the issue of grants as well. We've heard that most researchers are using their
own set aside funds to tackle XMRV. This makes sense; it can take quite a while
to develop the granting and get it funded. It has been almost 7 months since the
big Science paper came out.
Have any XMRV grants been funded? (We do know of several grants that have not
been funded; Dr. Mikovits has said several grant requests have not gone
through). The ProjectRePorter site has replaced CRISP as the main information source for federal grants. I ran XMRV
through that and came up with three grants.
The first awarded to Michael Dean ($701,000)was hard to interpret but Michael
Dean is interesting because he is interested in ABC transporters which may be implicated in RNase L. dysfunction. If I remember correctly these
transporters maintain the ion gradients between the cell and its environment. I can't figure out what the
XMRV connection is but he is involved in an interesting aspect of CFS research that hasn't gotten much play.
The second, which was awarded to Christine Kozak for $668,000 from the NIAID in 2009, is focusing on factors that block
gammaretrovirus entry into the cell first in wild mice and then in primates and humans.This
could prove helpful in stopping the virus from further infection in the body.
The last was awarded in 2010 to 'our own' Dr. Ilya Singh of the University of Utah. This $312,000 study is
directed mostly at prostate cancer but will be taking a close look at how XMRV replicates in culture and she'll
be looking for XMRV in other parts of the body as well in the general population.
It'll be very interesting to see where else XMRV shows up in the body.
In conclusion, XMRV proposals for CFS or other aspects of the virus
have either not made it through the grant cycle or have not been successful. I expect that will change soon
and we'll start seeing many more successful grants making it into the system.
- Dr. Bell's XMRV Tour continues
- Dr. Bell has talked in New York, California and Canada on XMRV and thanks
to the European ME Alliance his XMRV tour will continue on 'the continent' this
autumn potentially hitting Ireland, Sweden, the UK, Norway, Belgium and Spain.
Find out more about it
here.
- Dr. Deckoff's XMRV Trial
- Dr. Deckoff just reported on her and her daughters
continuing experience with anti-retrovirals. You may remember that she experienced a
significant burst of energy and a large symptom reduction about six weeks into
her AZT/Raltegavir trial. Then she plateaued - which is apparently what
one expects with AZT; the drug kicks out the active infection in the periphery
of the body first - bringing relief and then digs deeper for the virus in the
rest of the body. She tried and then tanked on Tenofovir after that.
Her daughter experienced an increase in energy about six weeks in but then she had an upsurge in
inflammatory symptoms and after that returned to baseline. After both went off Raltegavir both
worsened and both went back on it and both felt better. After that her daughter went on Tenofovir without
experiencing any side effects (in contrast to her mother). My impression was that both had improved
but substantial symptoms continue to dog them and the treatments are having
very individual effects. Dr. Dekker provides some interesting technical
insights into the antivirals
later on in the blog.
May 21st
- The XMRV Plus Survey Is Here
- Kim, Advocate, Julius and others on the
Phoenix Rising forums began working on a comprehensive survey to characterize
people who tested positive to XMRV in January. It was alot of work and it
resulted in a very professional survey. They've also enrolled
statisticians who will mine it for information. If you've tested positive for
the virus please take it and add to the knowledge. You can find the survey on a
nice-looking website
here and
a discussion about it here.
- Dr. Klimas hints
about a positive CFS study - In her latest video overview of research
findings in CFS Dr. Klimas hinted (basically said) there's a positive XMRV study
in the mix coming up. Could it have been the German study? It seems unlikely
because (a) it was a German study and Germany is a long way away and (b) the
German study was not on CFS. This suggests that a study in the near future will
indeed find XMRV in CFS patients :). She also said there's a negative study
coming out. Lets hope the positive one is more comprehensive and the negative
one is another 'thin' study. For a discussion
check here.
May 20th
- WPI on TV
- Annette Whittemore and Dr. Donnica Moore talked about CFS and XMRV on
Nevada Newsmakers. (The WPI is now a sponsor of Nevada Newsmakers - how interesting to see a CFS organization
pop up on the TV; that's a change of pace). Dr. Donnica related about her triathlete husband coming down with
CFS and then years later a flu sweeping the family leaving her very athletic son with ME/CFS while she and
her daughter recovered. (In that family the guys got it - a real twist). Its easy listening to this to
see how Dr. Donnica became a media figure - she's got a clear strong voice, she's very organized - she's
made for this stuff.
This is a pretty substantial talk lasting about 20 minutes (with commercials). Annette noted that there
have been 23 new papers on XMRV since the October Science paper -truly an amazing jump in interest in the virus. She
noted that since the Science paper came out the WPI has detected XMRV in about 5-600 ME/CFS patients.
Sam Shad, the host of the program, came up with one of the strangest questions I've heard yet - the cost to
society of possibly finding the cause for CFS. He noted that countries like Great Britain that have a national
healthcare system are worried about the cost associated with finding a virus like XMRV that causes CFS. Its
hard to get over how bizarre that question is but that point has apparently been raised in the UK.
One might ask what about the
costs of not finding the cause of ME/CFS? What about the human costs? The high economic costs associated with the disease?
Dr. Donnica noted that if a country is going to support disabled people then it should support
all disabled people. (You could say the same
regarding CFS research in this country; if a country is going to support medical
research into diseases it should support medical research into
all diseases.) She noted that a recent study found that the quality of life
for children with ME/CFS is worse than that for children with type I diabetes or asthma. "What people need to understand" she said is that
this disease causes significant disability and significant reductions in quality of life"
We then learned that Annette Whittemore has had communications with Dr. Francis Collins of the NIH and. of course, with Senator Reid.
She noted that Senator Reid (please let him be reelected :)) has been a strong advocate for CFS for years and years. Dr. Collins communicated that
the NIH is in a 'wait and see' mode regarding XMRV but that they are sponsoring the International Conference on XMRV that's coming up which
she was encouraged by. Check out the
last segment where Dr. Donnica takes Sam Shad to task for using the term chronic fatigue rather than chronic fatigue syndrome while ignoring
his attempts to tell her time is up :).

- XMRV is...is.....is....There! - Yes, someone actually found XMRV.
(Gasp). They weren't looking for it in
the blood or in prostate tissue or in CFS patients and no, it wasn't a US Lab that found it, it was a German lab
remarkably enough but after months of no positive results it was
remarkable finding...XMRV
ppears to be alive and well in Europe, and, of course, if it's there it's
probably everywhere.
This German team lead by Dr. Fisher looked for XMRV in
respiratory secretions - a highly targeted bodily fluid by researchers, no
doubt, because of worries about XMRV’s infectious nature. Since many viruses are
spread by coughing, kissing (we know all about that one) or sneezing one of the
first things (after the blood) researchers will want to know is if it's alive
and well in the respiratory system.
These researchers used PCR to search for XMRV (and other viruses) in
respiratory samples from about 260 people with respiratory infections who were
healthy, had chronic obstructive pulmonary disorder or who were
immunocompromised because they had undergone an organ transplant.
They found XMRV in about 3.2% of the healthy controls (very similar to the
WPI’s 4% report of XMRV infection in the blood of healthy controls) and COPD
patients and about 10% in the immunocompromised patients. The increased
prevalence in the immunocompromised patients, of course, suggested that the
immune system plays an important role in keeping this virus under check, and if
the immune system is compromised then the virus can either be reactivated or
perhaps gain entry for the first time into the body.
ME/CFS? - What does this say about CFS? It’s hard to tell.
We’ve always known that XMRV could be an ‘opportunistic virus’; one that does
not cause ME/CFS but exploits the damage that has already occurred - which appears
to be what happened in these immunocompromised patients. Indeed,
if you were going to find an infectious retrovirus anywhere you'd probably find
it in these transplant patients because the drugs they take turn down the immune
response causing them sometimes to collect pathogens.
Some would say the same type of process occurs in ME/CFS but not
everybody thinks the amount of immune dysfunction found in CFS is particularly
significant. Some researchers certainly do but others characterize it as ‘mild
immune dysfunction’. It would be very instructive to compare the degree of
immune dysfunction in these two sets of patients. Is it six or seven times
higher in ME/CFS patients than in transplant patients? Is that why its present
in 6 to 10 times more ME/CFS patients?
I wouldn't
think so. If not, then why is it apparently showing up in such a large percentage of
CFS patients and in such smaller percentages in patients the medical profession
in general really does consider immunocompromised?
An opportunistic virus wouldn't do that. A virus
that somehow targeted CFS patients would however. My guess is
that XMRV is still a special problem for CFS
patients and that it just happens to be in immune compromised patients (along
with whatever other pathogens they have) - as well; ie the theory that XMRV
could cause ME/CFS is still alive and well.
My takeaway from this study is that, unless this lab made a big error
somewhere, the WPI’s finding of XMRV is considerably strengthened and this study
is a big and much needed win for them. It shows that XMRV is present,
puts into question the findings of the three negative studies, and puts the onus
on other researchers to find it. The fact that these researchers did not use the
WPI’s techniques to find the virus further strengthens the overall XMRV finding.

May 17th
- Interviewing Dr. Coffin - the crew at the Phoenix Rising Forums has been busy. Rrrr - went so far as to
contact Dr. Coffin, one at the top retrovirologists in the country, and ask him some questions about XMRV.
Tracking XMRV Down - What is he and Tufts University doing on XRMV? - Dr. Coffin is looking far, and has not yet found, the exact
mouse virus that gave birth to XMRV. He's working with Dr. Huber - who's also studying endogenous retroviruses in CFS. Dr. Coffin
seems to be be doing a bit of backchecking on XMRV. We knew that it was REALLY close to
a mouse virus and he said he was
checking to be sure the XMRV really is in the human DNA and is not from mouse droppings (ie is a contaminant). He seems to
be referring his own lab (?) with regard to this since this doesn't appear to be an issue in the Science paper. He did note that
the NCI is developing extremely sensitive assays for XMRV in the white blood cells.
Put That Bug on Trial! - When asked if his thoughts about the Science paper had changed since the negative studies came out he simply
replied "He'd feel a lot better if other studies had confirmed it" (To that I say "so say we all"
:)). Rrr reported that Dr.
Coffin believed XMRV could be a cause of CFS or simply a passenger virus that didn't cause CFS but was taking advantage of
the damage caused by what had caused CFS. He also, surprisingly, felt that it was time for a clinical trial of antiretrovirals.
(He's far ahead of the curve hear). A successful clinical trial is kind of
the ultimate test of XMRV's role in CFS; if it
works then XMRV (or another retrovirus) is definitely present in CFS. You
can throw away all the negative PCR tests if that happens. Of course it's hard to get a clinical trial going
before an Association between XMRV and CFS is proved but he's all for it.
Comparing the early days of HIV and CFS (only 7.5 months now) Rrr reported he said
" The science community is very mobilized since the Science paper" but that things could have been moving much faster
if the early studies confirmed XMRV's presence. (Dr. Mikovits too noted that things that the WPI thought were sent to happen
were put off after the negative studies appeared.)
Blood Test Ready....NOW -Rrr asked about a definitive blood test and had the impression that one had
just come in and that Abbot labs - the main labs behind the HIV blood test - have provided it.
That's a huge step forward and means testing should proceed much more quickly. Interestingly Rrr reported
that he said its going to be part of the screening process for the nations blood
supply (which does kind of suggest that they're finding it? Why screen for
something that's now there...but I may be going too far in my interpretation).
Anyway we're going to know sooner
rather than later about the association between CFS and XMRV - Dr. Coffin said
its a matter of months now.
Evasive Little Bugger - Since the negative results came out we've wondered if there would be a different strain in
Europe that's evading researchers attempts to find it and Dr. Coffin said that 'a lot' of people are trying to figure out if
XMRV is more diverse than it first looked. (Remember all PCR does is look for pieces of genetic code - not the whole virus...if those
pieces happen to be different....)
Check out more of the interview and
a discussion here.
Thanks Rrr!
- Letter from Barcelona - Cristina Montane provides some updates
on three new studies in Spain.
The Institute
Ferran is getting together a large study (200) that is hewing close to the
original Science one; 100 patients will have to have demonstrated abnormalities
(probably cortisol/nitric oxide) on the repeat exercise tests - these people definitely have
post-exercise problems - and congratulations for the Institute on taking up both
the repeat exercise and XMRV findings so quickly. The Institute Vall Hebron in Catalonia,
under Dr. Mikovits direction,
will be testing 100 people; both groups are waiting for a homogenized test kit
to come available. Finally Dr. Clotet's Retroviral lab is looking for XMRV
in 12 patients.
Cristina closed her email by noting just how important the CDC and NIH's tests are looming; after the
negative results researchers around the world are apparently waiting on these
groups to know what to think....
May 13th
- XMRV Study Picture - we haven't had any studies published for over 10 weeks. Where are we know with the studies? We
have 24 studies on the board. We're starting to get an idea of which studies are firm and which are not. The
bad news is that we really unclear about alot of studies; the good news is that
the list of 'Firm studies' is fairly hefty and contains some real heavyweights.
No XMRV Found - Imperial College, Kuppeveld, Groom, Joliceur
Anyone's Guess - Dr. Bell's and Dr. Klimas's three studies, the Panorama Research
Institute's Study, the Lloyd study, Barnes Oxford, Montoya's Stanford study, Kiel University study,
Pisan study (any reports on these?)
In the Queue - Dr. Hubert's study and the CDC study are reportedly in the publishing queue
The Swedish study was reportedly postponed after its lead research was killed in an accident.
The Firm Studies : the CDC
study, the DHHS Study, National Cancer Institute Study, the Bateman/Sing study,
the InvestinME/WPI study, the CFIDS Associations Biobank Study, the Bannert
(Robert Koch Institute) study, the Huber Study, Columbia/Cornell/WPI study.
The InvestinME study, ironically - since it was built off the unused funds of a negative study
- may turn out to be a really important one, since it is the only other than the DHHS study, which we know is exactly replicating
the Science Study. The WPI is providing the blood but an independent lab is
analyzing it. It appears to be moving fairly quickly as well. (The CFIDS
Association BioBank may be replicating the original study as well).
Check out the XMRV Study Page here.
May 11thh
- Swedish Study Postponed- Several participants on the Phoenix Rising Forums reported that a promising Swedish
study planned to finish in Spring/Summer, that was going to look for XMRV in patients meeting the Canadian Consensus
Criteria has been postponed because of a tragic auto accident that took the life of the lead investigator.
- Phoenix Rising Poll Results
- Thus far of 28 people taking the
culture test for a latent infection poll 53% have tested positive
and 47% negative. Some negatives will reportedly turn to positives once the
antibody test is ready but it's not clear how many (10%?/20%). Of the 28 people
that have taken the poll 70% of people with severe ME/CFS are positive, 50% of
moderate to severe and 60% of mild to moderate ME/CFS are positive - no strong
evidence yet that severity affects .the likelihood of testing positive.
- Dr. Deckoff Reports - Dr. Deckoff made a splash when she strongly advocated that
very ill patients try AZT now. She included herself in that group and for the
last month and a half or or so has been following her own advice and taking AZT and a
drug called Isentress. In her latest update she reported that after about 6
weeks on AZT and Isentress she noted a substantial increase in energy allowing
her to do errands in town without much trouble. When she added Tenfovir her
symptoms increased dramatically.
She's definitely not a typical CFS patient. Until she had what she called a disasterous course of
antibiotics for Lyme disease she noted she had little fatigue but all sorts of other autonomic/nervous system
problems.
According to her blog she stopped Tenfovir.
She's following the progress of 8 CFS patients. The sample size is small but
she's found that AZT alone was causing 'very modest improvement' and that
patients were adding Raltegravir. When she personally went off Raltegavir for
five days she found that her symptoms increased again. At least at
this point she believes that these drugs definitely 'move the illness' ie cause
improvement but are not 'the answer' - which is
basically what you would expect from an off the shelf drug.
May 7th
- XMRV Goes Cold or Warm at Cold Spring? - We're learning one thing; when the interest is there
researchers swarm to a field like bees on honey. The grant process is generally a long one -most of the work is probably
being done using 'discretionary funds' but it is being done. Thanks to subtr4ct on the Phoenix Rising Forums for
providing the titles of XMRV talks/posters from yet another retrovirus conference
: this time at Cold Harbor, NY - the site, as
you may remember, of the CFIDS Assn/NIH Banbury Conference on CFS last year.
Sandra Ruscetti, an important researcher in the XMRV effort, will be giving a keynote speech at the May 24th-29th Conference. All we have are the titles -
and there are alot of them; 20 talks and posters on a virus that was pretty much a niche topic a year ago this time.
The Joliceur Study in Canada Comes Up Zero - ("XMRV is not
detected in Quebec patients with chronic fatigue syndrome"). We don't know much
about this study. We believe it was a fairly small study containing 50 patients.
We know that the lead author, Z. Hanna - a Canadian retrovirologist, publishes
fairly regularly but not at the level of say, a Dr. Silverman of the Cleveland
Clinic. We know the study is being presented on a poster - not a talk. We
don't know what methodology was used. We do know to be wary of small
studies and we know that we should probably
not expect
positive results from a study that does not replicate the WPI's
methods exactly. Basically we know not to get alarmed about the results from
this study; if this is a small group using standard PCR techniques then this
result would be predicted. Negative studies are not great news but we'll have to
learn more about the study
before we can assess its importance.
Australian Study Does Not Find XMRV in Prostate Cancer - AL Aloia, the author of the study, is an
Australian Researcher - so I'm assuming this is an Australian study. Interestingly he/she doesn't appear to have a background in either prostate cancer or retroviruses so his/her
connection to this is a mystery.
More Sensitive Diagnostic Tests on the Way - J Das Gupta, the author of "Development of highly sensitive assays for the detection of
XMRV nucleic acids in clinical samples", on the other hand, is a known quantity. A co-author of the Science paper and a colleague
of Dr. Silverman's, he's right in the mix of things. It appears the Cleveland
Clinic is making rapid progress in its
ability to detect XMRV using PCR - which is obviously a rather sensitive topic at the moment :).
Meanwhile Dr. Silverman is concentrating on trying to figure out
what XMRV does, rather than if it's there. His study "Comparison of XMRV infections in humans and rhesus macaques" illustrates the
weight this clinic and others have given to XMRV; they skipped over the laboratory rat phase of testing
and went straight to the primate phase - an obviously much more expensive, as well as informative animal model.
(What a shame it has to be done, though :( ). He's not alone, Qui X appears to have found antibodies in XMRV infected primates "Immune responses in XMRV-infected rhesus macaques—Serological markers of XMRV infection")
Treatment Pluses - Two studies titles suggests researchers have found compounds and/or anti-HIV drugs
that may be able to inhibit XMRV.
There's quite a few more titles -check them out here.
-
XMRV International "Workshop' On XMRV -
for all the stumbles of the past few
months for XMRV, the Scientific Community is showing increasing interest in the
bug. Dr. Coffin, Dr. Silverman and others announced that the NIH is funding an
interactive workshop on XMRV from September 7-9. They apparently announced it
now in order to give researchers a chance to clear a time slot for it since the
most precise location they could come up with was 'East Coast' USA. Here's some
info on it:
"The objective of this scientific conference is to assemble an international
group of scientists, physicians and epidemiologists to present and discuss, in a
public forum, the latest XMRV studies on a range of topics including virus-host
interactions, cell type tropism, mode of transmission, animal models and the
efficacy of current antiretroviral drugs.
This meeting will offer an interactive setting where the latest developments in
the field can be presented in order to evaluate the state of our knowledge,
address controversies, and develop an understanding between experts that will
help direct future research."
May 4th
- Top Retrovirologists Back XMRV- On the worldwide stage (for retrovirologists :)) at the Centennial Retrovirus
Conference in Prague, Dr. Ruscetti of the
National Cancer institute and Dr. Coffin, a top retrovirologists, strongly defended the XMRV finding. In a translation of a Dutch report Dr. Coffin
reportedly said
"People have raised the issue of contamination but nothing is known about at the moment. There is no proof. Much
of the research is done at the NCI, in the laboratory of Francis and Sandra Ruscetti. They have a long experience with these viruses and
are very cautious." Indeed, both of the Dr's Ruscetti are long-time employees of the National Cancer Institute - one of the most
highly thought of institutions in the world. Dr. Coffin also noted a key difference between the original Science
paper and the 3 validation studies; the fact that only the WPI study has 'grown' the virus:"None of the negative
studies have been published so far, the virus is grown," said Coffin. "Only in the Science study has been done, and that is a very strong
point."
Dr. Ruscetti, one of the co-authors of the original study, evinced considerable frustration as he let loose with a
blast probably rarely seen in the staid retroviral world calling the Dutch researchers burial of contrary results unethical and poor Science to
boot ""I do not know how they think they get away with this ethically," said Ruscetti. "I do not think this is good science."
Dr. Mikovits said she'd never seen anything like it and Dr. Ruscetti apparently
never has either. He noted, as Dr.
Mikovits repeatedly has, that the WPI, NCI and Cleveland clinic tested XMRV in four different ways and all checked
out. The negative studies only looked for XMRV in one way (PCR) using a methodology that both researchers
felt was problematic. Dr. Ruscetti also expressed his
dismay about what he called a 'whisper campaign' about contamination.
The WPI and XMRV got a strong endorsement from two reputable researchers. They highlighted one of the Dr. Mikovits
strongest points - that the negative research on XMRV is relatively 'thin' while the positive research is 'deep'. There may be three
negative studies from three different groups -that does count for something - but those groups took a
decidely thin slice at the virus. WPI, on the other
hand, took a thick slice at the virus- cross-checking their original finding in a variety of ways. Dr. Coffin and Dr.
Ruscetti clearly believe that quality trumps quantity at this point; one 'deep' study is more persuasive
to them than
three 'thin' studies.
May 1st
- The April Surprise - Our April surprise turned out to be a real shocker
with Dr. Peterson leaving the WPI and returning
to fulltime practice at his clinic. The WPI has remained almost completely silent on the move
- the Facebook site posted something and then took it down (transparency is not
the order of the day this time ( :)) and no further reports have been made.
Although the notice said Dr. Peterson's 'retirement' was 'planned' it was
apparently a relatively recent plan; ie Dr. Peterson had not planned to
dissociate himself from the WPI when he took on the medical director's job.
Whatever the cause of the split Dr. Peterson wishes the WPI well and the WPI
wishes him well and we wish them both well. We will all move on from here.
Does Dr. Peterson's leaving the WPI effect XMRV? It doesn't seem that it should. XMRV's fate has essentially been out of the WPI's
hands since the publication of the Science Paper in Oct. As much as we talk and ponder about WPI we should remember that
its a very small Research Institute - consisting of a quite small staff. The WPI started the XMRV ball rolling but
has never had the capacity to decide it's fate; the other
researchers in labs that ended up picking up the ball will determine its fate
- Dr. Peterson's departure will have no effect on them.
A Long Lag Time - Not only didn't we have the much anticipated 'April Surprise' but its now been 9 weeks since the last paper on ME/CFS. It took about
9 weeks after the Science for that first paper to appear and two more followed over the next six weeks. The long lag time suggests the upcoming papers
will, hopefully, be more comprehensive.
- Dr. Mikovits at the IACFS/ME - Pt II:
The Q&A session at the IACFS/ME was full
of intriguing questions and even more intriguing answers. Dr. Garth Nicolson's
question about XMRV infection in family members surely revealed why Dr.
Mikovits, so early on, got interested in co-occurring illnesses. She reported
that two thirds of the XMRV positive patients in the Science study had a family member who
also tested positive. She stated that most of them are ill with another disorder such as
fibromyalgia or autism or cancer. She said the rates of cancer in some of these
families is frightening.
(This in itself is a rather bold thing to say - cancer
being such a frightening disorder. Just to be clear, although publications on
this subject are pretty sparse - there's little published evidence yet that
cancer rates are increased in CFS and Dr. Mikovits findings findings - while
certainly accurate -have yet to be validated statistically. Of course, it
possible that XMRV could play a factor in several disorder; ie. that it may
contribute to CFS in one person, FM in another, autism or cancer in another -
that's certainly the WPI's thesis. We don't know, though, that
XMRV is a cancer-causing virus; in fact a recent study suggests that it may not
be as effective at turning on 'oncogenes' as was once suspected. We're
still in the conjecture phase; surely, when/if XMRV is validated these
types of studies will occur.)
Those XMRV Experts -
in a more humorous vein
Dr. Mikovits was asked about those 75 XMRV experts that were reported to meet at the Cleveland clinic in December. She
noted she would be 'surprised' (make that very surprised) to learn there were 75 top XMRV researchers
in existence at that time. It doesn't take a genius to see how right she must be. XMRV was discovered (and then mostly
ignored) by the scientific community in 2006. Until recently its been the focus of a couple of research groups
in the US and Europe.
The Two Big Bugs in ME/CFS - another surprise came when Dr. Mikovits was asked how she felt HHV-6 and XMRV - the two
big bugs in ME/CFS interacted. The fact that she has no reason, at this point, to believe that they
(or any other bug) interact together at all, is
certainly gives rise to some caution about XMRV's role in CFS. She noted it is possible that XMRV infection
could disturb the homeostatic equilibrium in the body that kept other viruses in check or that these
viruses could send signals that up or down regulate XMRV activity. At least at this point - the WPI's data indicates that XMRV infection
does not appear to increase the risk of CFS patients having another infection.
Was the Past Prologue? Are the percent positive rates remaining the same in people tested after
the Science paper? Yes, as was indicated elsewhere - they appear to be; in fact the percent positive rates
in co-occurring diseases (apparently FM and autism) appears to be higher than expected - about 35%.
There's more in the Q&A Session -
check it out here.
- Pen Pals
-Annette Whittemore was so incensed with Dr. McClure and Dr. Kuppevald
that she posted rather blistering letter on the WPI's website
questioning the Groom and Kuppevald's groups integrity. Specifically she noted
the two groups had not mentioned that the WPI had found some of their samples to
be positive for XMRV. In keeping with this rather public transAtlantic
letterwriting campaign the Kuppevald Group posted a letter of their own on their
website. They noted the 'serious allegations', wished Annette had been
'professional enough' to talk to them first hand, and noted some
'aggression' they felt was 'unscientific'.
They stated that Dr. Mikovits had told them at a Lisbon Cyotkine meeting that all the
patients in the study had come from Lake Tahoe. (The cohort question again! At the end of their
paper, the Kuppeveld group, questioned whether their negative results were due to the fact that
they did not have an 'epidemic' group.)
For their part they noted that they had not received the WPI's reports of
positive XMRV samples in their patient set until their paper was already in
press. (They also noted that it was rejected after a five week review by
Lancet). Interestingly, they noted that the WPI had sent them a positive sample
and that the Kuppeveld lab had been able to detect XMRV in it. They were unable,
however, to find XMRV - despite 'repeated testing' - in their samples which the WPI had reported were positive. They also reported that percentage-wise the WPI found roughly the
same percent of CFS and healthy controls were positive for the virus. The numbers were far too low for a statistical analysis -
just seven samples - but it was enough, given their ability to detect XMRV
in the positive sample the WPI sent over to them, for them to conclude the WPI's
had somehow contaminated the samples.
Then they threw the ball back into the WPI's court stating that they had offered to try and resolve the discrepancy by proposing that
the two groups exchange cohorts on Feb 9th! This is just the procedure that outside researchers have been calling for for several months.
They stated that the WPI never replied to their request.
Yet there's more to this story.
In the best explication of the controversy I've seen,
a Dutch journalist, asked Dr. Mikovits about that
positive healthy control. She noted that it could have come from a family contact. (We've just
seen Dr. Mikovits report that the rate of infection in family members is fairly high.) She noted that the
Mikovits/Kuppeveld groups had communicated frequently - about every three or four days - but that the communication stopped
about a week before the publication of the Kuppeveld study in BMJ. The WPI, having sent Kuppeveld materials
for a full replication of the Science study (culture, antibody tests, protein
tests) had expected the group to replicate the Science study. Whether or not
the Kuppeveld group ever intended to do so is unclear, but it is clear that,
after the negative PCR findings, they never attempted to go further.
With regards the Kuppeveld's request to exchange cohorts, it was clear that Dr. Mikovitsfelt
the Kuppeveld group was a dead end; she didn't trust the group to fully
replicate either their PCR tests or to attempt to replicate the other important
parts of the study - therefore she declined to participate.
- Conclusion:
what we need are multiple groups sharing large numbers of patients
using agreed upon techniques
-no more questions about culturing vs non culturing
-no more questions about not going the whole hog
-no more questions about cloned samples vs real samples
-or good cohorts vs weird cohorts
-or good researchers vs bad researchers
Thankfully Dr. Mikovits has agreed to participate in those studies; in the end
we'll (hopefully) have an answer that everyone can agree on. I hope they live up
to our expectations.
I would note that neither of these groups - the WPI or the Kuppeveld group - are
going to decide the fate of XMRV. Their argument, with regard to that, is almost
beside the point. If what we've been told is true about the DHHS study and the
CDC study, and if as many groups are studying this as we believe, the work that
is being done right now will decide this issue long before they conclude their
argument.
I can't wait for those studies (although I will surely peak at them through closed hands at first).
April 28thh
- Dr. Peterson to leave Whittemore-Peterson-Institute!
- in a surprising announcement the WPI, in a very
brief statement stated that Dr. Peterson is leaving the medical director position at the WPI and returning to
his medical practice at the Incline Village. The WPI is beginning the search for a medical director to take over the
position when the WPI opens in the fall. No reason was given for Dr. Peterson's departure other than to say that
it was part of a 'planned' tranition. Dr. Peterson stated that he was proud to have been part of the creation of the WPI. The annoucement did
not state what, if any role, Dr. Peterson will play in the Institute in the future.
- Dr. Mikovits Talks Again!
- Dr. Mikovits is everywhere. The IACFS/ME did a very interesting thing by inviting
Dr. Mikovits to answer questions from their members. Not surprisingly, she got some very interesting questions. The first really
illuminated what a complex process tinkering with the immune system is. Andrew Bokelman essentially asked -if
you give CFS patients something (such as a neutraceutical) that activates the immune system - causing
natural killer cells to increase - if those natural killer cells are infected, as has been reported,
with XMRV, aren't you just
spreading the XMRV infection?
With every answer we learned a little bit more about XMRV. Dr. Mikovits
noted the critical fact that while XMRV may be present in many cells it doesn't appear to be very active
in many cells. (We've heard before that XMRV does not appear to be very active in many immune cells - which, of course,
brings up the question -just where is it active? ie. what is its tissue reservoir?
and what effect, if any does it have on immune cells?). In any case, Dr.
Mikovits stated that we don't have to worry about empowering XMRV when we enhance NK cells; the
WPI has been able to enhance NK cell killing levels without increasing XMRV replication.
Sex and XMRV - Dr. John Chia asked how XMRV could be transmissible via blood, sex and body fluid as stated in 'the newspaper article'
- when there is little epidemiological evidence of infectious transmission in CFS. He noted that
long before HIV was determined to be the cause of AIDS it was pretty clear that sexual transmission was involved;
researchers were able to chart the transmission of HIV from person-to-person simply by following their sexual partners.
This is clearly not true in ME/CFS.
Dr. Mikovits stated that sexual, blood and body fluid transmission was
only suggested by the Science paper and that newspapers went too far in stating
that it occurred. She then noted, though, that unpublished work indicated that
XMRV was 'very stable' (ie it can survive in many different environments) and
appears to be very 'transmissible'; ie it does indeed
appear to be transmissible via
the blood, sex and body fluids.
She didn't answer, why, if this is so, CFS itself does not appear to infectious in nature (ie does not generally
occur in outbreaks - and is not usually transferred between say, a husband and wife.)
Of course just because XMRV is easily transmissible does not mean that everybody
who has it will get sick. It could be quite prevalent in families of ME/CFS
patients but does not manifest itself in most people as CFS. The WPI is testing
families of ME/CFS patients now.
Posting a Ride on the Immune System - A few questions ago we
learned that enhancing natural killer cell activites does not, at the same time,
help XMRV spread through the body. In her answer to a question on the
effectiveness of new biotech drugs for XMRV, Dr. Mikovits stated that the WPI
does believe that the 'hyper-active' immune system often seen in CFS
helps spread the virus throughout the body and she suspects that XMRV may have a 'tissue reservoir' (ie be rapidly
replicating) in the lymph nodes. Thus drugs that rebalance the immune system or just turn its
activity levels down could be helpful. (This is a tricky strategy; if a revved up immune system is indeed fighting off a pathogen,
then turning its activity levels down could give the pathogen the break it needs to spread. If, on the other hand,
the pathogen is using a hyper-active immune system to spread - then tamping down the immune system
could be helpful).
About That PCR Test Again... - Nancy Klimas asked why VIP Dx was no longer using PCR? (PCR was, after all, the major finding in the Science
paper). Dr. Mikovits reported that PCR was the least
sensitive procedure for finding XMRV and that "the realization by the negative studies that
only 1 in 1 million resting white blood cells harbors a copy of the XMRV provirus". (Granted that XMRV is less easy to find by
PCR than other tests....but its still hard to understand why the WPI didn't realize XMRV was that
hard to find until other
groups start looking for it? They had, after all, been studying it for a year by the time the first validation study came out.) The
WPI's Science article that reportedly answers many of these questions should be out within the week. If Nancy Klimas, a big early booster of XMRV, is still
unclear about the PCR issue then you can be sure many other (less positively inclined) researchers are. It will be good to get that
Science article out. (Dr. Klimas is waiting for more clarity in the testing situation before she
tests her patients)
XMRV - the Cause of ME/CFS? Does XMRV by itself cause CFS?
Or is it one of several necessary factors needed for CFS to occur? Dr. Mikovits
stated that XMRV is necessary for CFS but that the WPI's current hypothesis is
that it needs partners to cause it. She believes XMRV causes an immune deficiency which allows
other pathogens to sweep in and cause the symptoms of the disease. She did leave the door open for
XMRV by itself to cause CFS.
That Immune Deficiency - Do CFS patients infected with XMRV have any signs/symptoms that distinguish them from
people who are not infected with XMRV? The 'big' questions just kept on coming.
Were people with XMRV different from people who didn't have the virus? This question is another
big hurdle for XMRV. In order for it to be a major factor the patients with it will have to be different
from those that don't have it.
Not having the ability to track signs and symptoms in these two groups yet
Dr. Mikovits didn't know about those but she did note that of all the immune markers they tested (RNase L, other pathogens, cytokines and chemokines) that only one - Interferon alpha -
correlated with XMRV. This, of course, is interesting given the WPI's theory that XMRV causes immune hyperactivation leading to
immune dysfunction - which then opens the door to the other necessary co-factors such as pathogens, which take the patient
down the same way HIV-associated co-pathogens take AIDS patients down.
This data, however,
suggests that XMRV does not open the door to other pathogen's and it
does not
play a role in the typical immune abnormalities we associate with ME/CFS. Data
like this makes discerning XMRV's role trickier. We would have thought XMRV
would be associated with the viruses and the immune
abnormalities typically present in CFS but it's not. XMRV is correlated with an important
immune marker (IFN-a) but that marker has not been traditionally associated with
CFS! IFN-a, which the CDC and Emory programs have shown interest in, is known, however, to produce fatigue and many of the other symptoms found in CFS.
But IFN-A was decreased in people with XMRV. Since IFN-a is an important
antiviral agent then decreased IFN-A could result in increased pathogens in
patients with XMRV, which doesn't yet appear to be happening. Anyone not confused?
My conclusion is that XMRV is trickier than we thought. If its going
to be a major factor in CFS its going to
have to effect parts of the immune system that have not thought to be perturbed
before. (Or it may affect non-immune factors)
A Big Question! - what percentage of CFS patients are infected?
As the time goes on the WPI's estimates of prevalence are rising. At
the CFSAC meeting, Annette Whittemore said basically - if you have CFS then
you're infected and that seems to be being borne out by the WPI's data.
Dr. Mikovits said that 75% of the 400 people meeting the Canadian Consensus Criteria have tested positive for the virus and that there
is antibody evidence
of XMRV infection in another 10%.
Another Big Question! (And a bold answer) - Will treatment for XMRV eventually return CFS patients to health? Dr. Mikovits said
she was "extremely optimistic that treatment of XMRV or its immune target(s) will restore CFS patients to at least 85% of the original health status even in the sickest of the sick."
Why such a bold prediction? Because the medical community has been able to do that with HIV - a virus that is far more virulent than XMRV is and which
has more severe effects on the immune system. She noted, quite aptly, that some people are able to recover fully or nearly fully
for years without ever having been treated for XMRV - something you could never say about HIV.
April 23rd
- Tainted Blood? - the list of countries who would just rather not see ME/CFS
patients blood in their blood supply is increasing. The US is waiting for
the results of its DHHS study but
Canada decided it was better to be prudent than risk possibly further
contamination of the blood supply. Few CFS probably give blood but there
are 340,000 of them in Canada.....A couple of days ago
New Zealand
decided CFS patients blood was hot to handle and
the Aussies jumped on board today. The Aussies apparently don't expect a
resolution of the XMRV issue soon as they stated they'll review their decision
in two years. Interestingly the NZ article states that CFS
was first identified in New Zealand by Dr. Peter Snow who fought hard against
the 'malingerer's label'.
- The AZT 'Crowd?' - yes, the WPI has publicly said do not try AZT until we know
more but, of course, some sick patients will be giving it a shot. Plus we hear
rumors that a few selected patients at the WPI are getting the drug.
LadyBugMandy has been reporting on her
AZT/Raltegavir trial on the Phoenix Rising Forums. She hasn't had an easy
time of it at all and may have to stop the drug. Another person has not had a
positive experience. Meanwhile a doctor with ME/CFS/Atypical MS, who has put
herself on AZT, posted an open letter advocating that seriously ill patients
should be given the chance to take the drug.
Open letter to the ME/CFS/Lyme communities. Please disseminate.
From: Jamie Deckoff-Jones MD
I am a 56 year old physician with ME/CFS/atypical MS. I have a daughter with
ME/CFS/Lyme Disease. I was an emergency physician. After I got sick, I recovered
enough to have a private practice. I treated brain injury with neurofeedback and
HBOT. In that context, I treated patients with Lyme/CFS/ASD/ PTSD/mood
disorders. I am also well versed in complementary, alternative, integrative,
functional medicines and bioidentical hormone replacement.
When I read the paper in Science about XMRV being highly associated with CFS, it
was apparent to me as a physician and a patient that this was it. When I
realized that the virus is sensitive in vitro to existing safe HIV drugs, I
thought and still think that it is a miracle. In fact, I am stunned by the
sudden overabundance of caution in the treating physicians. It would seem that
nobody wants to try it. Despite being given the key. Never mind that we are a
patient population that has been experimented on for decades.
Frankly, I didn’t see what I had to lose. We are culture positive at VIP Dx. We
have tried everything to no avail. So with the assistance of a wise,
compassionate friend who is an ID doc, and a smart family practitioner, I
started AZT 300mg on March 4 and Isentress 400mg on March 11, both twice a day.
It was my intention to wait for some sort of confirmatory data before reporting
anything publicly. But watching all that isn’t happening with respect to
figuring out how to help the patients, I don’t think that anything should depend
on how a few patients do, especially a patient like me who may have been
infected for as many as 40 years. I don’t think it is wise to wait while
scientists argue about the validity of lab tests. There are too many who need
help emergently. HAART is a safe existing protocol for AIDS which includes three
drugs which inhibit XMRV in vitro. We even know that the three possible
combinations of those drugs are each synergistic in vitro. But, the sickest will
die while the scientists try to figure it out, so it seems to me that it is up
to the doctors to treat with the information available. As always.
I believe that there is a rationale for treating the sickest patients now.
Physicians are allowed to prescribe drugs off-label. I think they should be
testing their patients, at VIP Dx, the only commercial lab right now that seems
to be able to find XMRV in peripheral blood, using the methods validated in the
Science paper. I would be happy to share with any physician willing to consider
treating.
I certainly don’t expect that it will be as easy as taking a few pills. There is
lots of downstream damage that will need to be treated. But treating all of the
problems that have been identified over the years in this patient population
will likely be more effective for many more patients than it has been in the
past. We will finally be able to identify the commonalities and differences in
the various neuroimmune cohorts. Always treat the causative agent if you can.
Then modify the host environment to the best of your ability so that whatever is
left functions at its highest possible level.
In my opinion, too many of our physicians have gotten caught up in their own
ideas and lost track of the goal, which is to get the patients well. As a group,
doctors and patients alike, we must support a willingness for the truth to come
out, whatever that is. New discoveries have to be incorporated into our thinking
as they occur.
I thought that it would be OK to sit back and let the dust settle. Whenever
momentous discovery happens in medicine, there is a flurry of resistance from
those who have been made wrong. But this is uglier than that. Now the WPI is in
need of funding. Connect the dots. And the band is playing on while we go down…
I am no activist. I am politically naive. But I know the power of the internet.
I know how marginalized we have been as patients. The people at the WPI are our
friends. They are fighting for us, when no one has. As a community, we are often
too sick to fight. So we have to let other’s slay the dragons for us. We have to
support them in any way we can. Read: SEND AS MUCH MONEY TO THE WPI AS YOU CAN
AFFORD. Please tell everyone you know. Pull out all the stops."
Sincerely,

April 23rd
- Dr. Mikovits Talks Pt. III
Funky Virus - Whatever the problems with the earlier
validation studys some of them did contain well known retrovirologists who, as
one commentator put it, "do know how to do PCR". So how could they be getting
such different results? One possibility, of course, is that XMRV is trickier to
find in the blood than researchers have suspected and that small differences in
different studies methodologies have made a difference. Another concerns the composition of the virus itself.
I asked Dr. Mikovits if slightly different strains of XMRV in Europe could be part of the problem
and, she said, after noting that HIV has two strains, and HTLV no less that
four (!), that it would be 'arrogant' to exclude
that possibility. She also noted that the fact that the XMRV antibody tests
sometimes find the virus where PCR tests do not, suggest that a different strain
of XMRV could be managing to elude the PCR's grasp. In fact she
stated there was a 50% false negative rate on PCR tests at VIP Dx (ie 50% of the tests negative for
XMRV by PCR were positive by other tests).
Still Confident - Dr. Mikovits is clearly frustrated at the lack of positive findings, the financial stress
that being placed on the WPI, and the lack of federal funding but she is still confident in the WPI's
results stating again that she does not see any way contamination could have played a role in their
findings. The WPI is doing two types of antibody tests; one, which is apparently the ELISA test
which measures antibodies
to the whole virus and is less precise than the Western Blot test which looks for antibodies to
a specific protein on a virus. The Western Blot
test is essentially a check on the Elisa test and Dr. Mikovits reported both
tests were providing similar findings; ie this is XMRV they are finding.
Busy, Busy - Dr. Mikovits was finishing up two Department of Defense proposals and then was off to Europe to talk to the British Hematological Society, then it was over to Spain to
work on XMRV study there, and then to a 100th anniversary of the discovery of retroviruses. That Science article,
by the way, should be out in about two weeks.
April 22st
- Dr. Mikovits Talks Pt II: The Letter - Annette Whittemore penned a rather
strong letter to Dr. McClure a couple of weeks ago. In it we learned that the
collaboration between the WPI and the Kuppeveld and Groom study groups was much more extensive
then we'd thought. In fact it turned out that samples sent from those groups to the WPI
tested positive for XMRV at the WPI's lab. Those groups, however, rejected the
WPI's findings and didn't mention them in their report. Dr. Mikovits reported that 3 of the 10 samples
Kuppevald sent to the WPI tested positive and one of those was from a healthy control. After Kuppevald
ran his own tests and couldn't find XMRV, he concluded that contamination had occurred
at the WPI.
A Collaboration Ruptured - Dr. Kerr had been collaborating
with Dr. Mikovits on another project but it's possible, given how upset the WPI
was about the way they felt they were treated by the Groom group, that that
collaboration is at an end. She felt the Groom group should have attempted to
reconcile the discrepancy between their results and the WPI's before they
published. She also felt that the WPI should've been kept in the loop about the
Grooms groups inability to duplicate their results. As it turned out they were informed of
the study results only a day before the paper was published. It's, of course, possible that
Dr. Kerr was under constraints of his own. In any case, it's a unfortunate situation.
We
obviously don't have Dr. Groom's or Dr. Kerr's or any other researchers take on why things turned out as they did.
Even in the CDC/DeFreitas saga - which churned up so much controversy - the two groups were talking about
their methodology frequently. This was definitely a one sided interaction.
Those Negative studies
- the negative studies have had an impact. Doors that were pretty open
aren't closed yet but it appears that projects outside of the WPI that were
going to pretty quickly gear up have been put on hold until the dust settles.
The WPI is in kind of a strange situation; they have lots of work to do - more
work than ever - yet, until XMRV is validated they'll have difficulty getting
big federal grants they need. Private donations of the magnitude that they
probably need, are difficult to come by in this economy. Money from the
diagnostic tests is certainly helping but the research is very expensive and
what they need are grants and clinical trials. Six months after the Science
paper they have not received ANY federal funding. Dr. Mikovits noted that the
federal government was spending billions of dollars on HIV, which affects less
than 1 million people in the country yet the NIAID (National Institute of
Allergy and Infectious Diseases), the huge pathogen Institute at the NIH, has
done absolutely nothing but XMRV.
The UK Study - on a more positive note - 50 of the
200 patients in the UK study have had their blood drawn and they are a very interesting group indeed. About 50% are homebound and
presumably never been anywhere near Dr. Wesseley and his cohort. It will be interesting, indeed
,to see how often XMRV shows up in these very ill patients.
Part III tomorrow
April 21st
- Dr. Mikovits Talks Pt. I! - Dr. Mikovits has been in touch with patients more than any other researcher
by several magnitudes and a couple of days ago I got to chat with her on a
variety of topics.
Some questions had been raised
about the WPI's two collaborators in the Science paper, the National Cancer Institute and the
Cleveland Clinic. We hadn't heard a word from any of them since the
just after the Science paper came out. Dr. Ruscetti of the National Cancer Institute did show up for
the CFSAC meeting in late Oct of last year but they'd been laying low since. Were they backing away from CFS and XMRV?
Had they dropped us in all the controversy? I asked Dr. Mikovits and she said both were still
working on the CFS/XMRV connection with the NCI more focused on CFS than the Cleveland Clinic. I was
just shown an email from Dr. Silverman of the Cleveland Clinic, however, to a CFS patient who promised that he
was working hard on it. Neither of the WPI'S main collaborators, then, appear to backing away from the XMRV/
CFS connection - they're just laying low and keeping their nose to the
grindstone -as researchers tend to do.
WPI? - but what about the WPI? We've heard that they are working feverishly away but was any of this
going to show up in print? Were we going to see any papers in the near future?
The answser to that is an emphatic 'Yes'! Dr. Mikovits reported they've
submitted no less than 5 manuscripts (yes, that's 5 papers) since Feb. One has been accepted and they're waiting
on word for the others. Papers generally take quite awhile to come out but they
are in the pipeline.
Papers, Papers - We know that,
in the end, that its ALL about the papers. We've heard (for over a month now!) that some papers are in
press. Dr. Mikovits stated she knew Dr. Huber's and
the CDC's papers were at the publisher and it sounded like she was feeling good about them. (Dr. Huber has
recieved a great deal of funding from the CFIDS Association to look for active endogenous retroviruses in ME/CFS).
Very early on she was reportedly very interested in XMRV. Because she is an
endogenous retrovirus expert and some people have worried about endogenous
retroviruses - it would be great to have a positive paper from her.
Life in the WPI Lab - what is the WPI actually working on?
Well, they're apparently putting alot of effort into finding out how prevalent XMRV is in other neuroimmune disorders such as autism, FM and atypical multiple
sclerosis. (Dr. Mikovits will talk at an Autism Conference this spring). They're refining their antibody (serology)
test (see below) and their 'infectivity assay' (?) and developing treatment protocols involving existing
anti-retrovirals (presumably raltegavir and AZT).
Testing - the testing/diagnosis news now all seems to swirl around antibodies-
the immune factors B-cells make that clump to pathogens and gum their works and make them easier for the big guns of the immune cells - the cytotoxic T-cells -
to 'blow up'. The big thing about the antibody tests is that positive results simply cannot be caused by
contamination - antibodies are produced by the body in response to infection -
not to a contaminant placed in a test tube. It is possible for antibodies to pick other viruses but as these researchers bear down on XMRV
more and more its less and less likely that any antibody tests they develop are going to pick up something else.
Dr. Mikovits reported in one of her earlier talks that Dr. Singh had developed an antibody
test that picked up signs of infection in people who'd tested negative for the virus by PCR. We know the WPI is
focused on antibody tests - I asked her whether they were using Dr. Singhs tests or one of theirs? Dr. Mikovits reported that the antibody
test they were using was homegrown at the WPI...and she thought it at least as sensitive as Dr. Singhs and my sense was
she thought it was probably more sensitive.
DHHS Blood Study - Its been what, five months or so since the DHHS announced they were going to look for the
virus in the blood supply. The Washington Post reported that things were moving along - that they were close
to
coming up with a test but Dr. Mikovits is on the team overseeing the study and she reported that because the
groups are storing the samples in a different way than the original study did - its taking longer to validate everything - don't
expect the results in the immediate future.
April 19th
- XMRV - A New Paradigm for CFS? Achieving Consensus
- Kurt Rowley, a frequenter of the Phoenix Rising Forums, penned
an interesting editorial on the process of achieving consensus on XMRV in the
CFIDS Associations ELINK. Kurt notes that
achieving consensus on a game changing arena - as XMRV could be - is often a roller coaster
ride, with many ups and downs manifesting themselves. He also aptly noted how rare it is for CFS to be in the middle of any
scientific debate.
Kurt described a long and drawn out process to get the full picture on XMRV; to what degree
its present in the disease and, even more so, to what degree it plays a role in the disease. He noted that
early in the process the two sides of the debate tend to get entrenched in their positions. As the
research presents itself they tend to modify their positions become closer and closer to consensus.
Interestingly, the NIH has a process they use to achieve consensus on a topic involving "State of the
Science" conferences, that they've used before with CFS. Kurt noted that while retroviral explanations
for diseases have often not panned out there are there are some notable exceptions. He then outlined
a possible way for consensus on XMRV to be achieved which included full replication
studies, more validation studies and more comprehensive studies involving culture and antibody
tests. If the XMRV finding is confirmed next would come large-scale population studies
involving CFS patients, other disease groups and healthy controls.
Kurt is clear, though, that this is a long-term process - particularly
given the complexity of CFS and the lack of clarity about how to diagnose the disease. He also believes
that simply the process of achieving consensus on XMRV will help enhance the publics understanding of
the disease and the need for better treatments and more funding. This is a fairly
technical but well written and organized article. I've just summarized a
small part of it. For the entire paper
click here.
April 17th
- Dr. McClure talks - Dr. McClure heads up the lab that the Imperial
College researchers (Cleare, Wessely) used to look for XMRV. They asked her to
help them with the study because she, a retrovirologist, was already studying
XMRV in prostate cancer. Prior to this she had no connection to ME/CFS.
Similar to other groups that got in the XMRV search early she runs a diagnostic
lab. Diagnostic labs such as Cooperative Diagnostics, ARUP in Utah and
her lab, can make a good deal of money if they come up with a good test for
XMRV. In retrospect, given their skill set and their focus, its not surprising
they were among the first to get into the game.
The interviewer's stance on the XMRV became pretty clear when he referred to
the 'industry' that had sprung up suggesting that retroviruses cause
CFS. Dr. McClure stated that she 'rushed' the paper into print because
diagnostic tests were being offered and, more importantly, patients were trying strong anti-retro viral drugs.
She has a point here. We now know that after Cooperative
Diagnostics came out with their test WPI pushed up their test which, in turn,
apparently spurred Dr. McClure to rush out her study - which came out about a
month before anyone else's. Given her results she wanted to dampen interest in
thise field - which we now know she (and others) did.that meant
Dr. McClure has her points but then she says "we wanted to put a stop to that because we felt it wasn't ethical". One
can imagine what that statement did to Annette Whittemore's blood pressure. Not ethical? The WPI
has been very careful not to recommend AZT as a treatment option for ME/CFS. They have repeatedly
stated that we don't know enough about the virus to recommend such a powerful, and possibly
damaging drug. (One can imagine Annette picking up her pen....Dear Dr. McClure...)
Dr. McClure acknowledges that a different strain of XMRV may be present in the UK but
she keeps the
heat turned up when she rather snarkily states that Dr. Lombardi
has pointed out this out 'ad nauseam'. That was it for the interview but it came they came on the heels of an
and another editorial and an interview, in which, if memory serves, she
called for 'good science' in the future (not this stuff). For a
- retrovirologist who had no prior interest in CFS, she's managed make herself the
voice of the opposition to XMRV.
Be sure to check out to the particularly discerning comments on
the interview.
April 14th
-
WPI Throws the Gauntlet Down - Yes, the WPI has been frustrated, and sometimes
vocally so, regarding the inability of the three XMRV studies to validate the
original Science study results. Yesterday, in a surprise announcement Annette
Whittemore threw the gauntlet down, so to speak. For sure she did it politely but
her proposal that Dr. McClure,
one of the co-authors of the Imperial College study, accept the WPI’s help in
learning how to find XMRV was the equivalent of that moon a glove slap across
the face. In the course of her letter we suspect that the WPI is frustrated at
more than the study results; they feel they’ve been done wrongly, that trust was
returned with a cold shoulder, and that breaches of professional etiquette have
occurred.
Dr. Mikovits previously reported that the WPI had extensive discussions with the
Groom group regarding how difficult it was to find the virus. In Annette’s
letter we learned that the collaboration went much deeper than this. It turned
out that both the Groom and Kuppenveld groups sent samples to the WPI -samples
which the WPI found were positive for XMRV. After that there was apparently
silence - it seems that the next thing the WPI heard from the UK was that there
was no XMRV in UK ME/CFS patients.
It’s a puzzling situation; the samples were presumably sent to the WPI so that
Groom and Kuppenfeld could check the efficacy of their procedures - a not
surprising step given the newness of the virus and the fact that researchers
were searching for it for the first time in the blood. In fact, in his talk with
Dr. Raccaniello, Dr. Goff stated he was ‘amazed’ that no one had yet shared
samples and he chalked that up to fact that they had not had time in their rush
to publish. Now we learn that samples were being shared - but not being
reported- and that the results indicated that both groups ability to find XMRV
might have been lacking.
We can’t say these groups could not find XMRV because they did internal
validation tests which indicated they could find the virus. But the acid test is
finding it in the patient’s blood samples and the WPI’s evidence suggested that
they were having difficulty finding it there.
This must have concerned them yet we get the sense that they made no attempt to
get to the bottom of the situation and ultimately discarded the WPI's results.
It appears that both groups, for whatever reasons, simply decided that the WPI
was wrong. (Perhaps this is why they did further validation tests?)
Chickens Coming Home to Roost -
Now the chickens have come home to roost, so to speak, in a very public way. The
WPI has publicly informed the scientific community that a) both groups had
discrepancies they did not publish in their paper and b) that the WPI is willing
to establish a very transparent procedure to figure out which group was
incorrect. Somebody is going to have egg all over their face before this is
done.
We should be clear that the fact that the WPI found XMRV and the other labs
didn’t doesn't mean that the WPI’s results are the correct ones. It’s possible
that the other groups do in fact have the correct findings. The WPI’s case,
however, is buttressed by a lot of supporting evidence (antibody tests,
sequencing tests, the ability to grow the virus) while these other groups have a
single PCR study. The fact that the WPI is taking the initiative here makes one
suspect that they are quite confident in how this will turn out.
Bringing Light to the Darkness? -
The way to figure out where the discrepancy lies is to share samples and that is
just what the WPI is proposing to do. Their offer to send their reagents and
other materials straight into the hands of, what many patients consider ‘the
Dark Side’ at the Imperial College is a bold one but does indicate that the WPI
trusts these groups to conduct these tests honorably.
One is getting the feeling that the boil is going to blow in the not too distant
future….the big Fed study appears to be about halfway done, the
Bateman/Light/Singh/ARUP team is plowing forward with a second study on XMRV,
the CDC study is reportedly in press…the quickie studies appear to be over - the
big studies are on the way - XMRV is getting more interesting all the time….
For now the ball is in Dr. McClure’s court.
April 11th
- An ME/CFS Researcher on XMRV - Dr. Baraniuk, who was featured in the last Phoenix Rising
newsletter, ('Proteins On the Brain: Spinal Tapping for CFS') has penned a review of XMRV in
the Current Allergy And Asthma Journal. Dr. Baraniuk is
a trained allergist with a heavy interest in autonomic nervous system functioning. His Brain Proteome
paper of a few years ago could, if it's findings are replicated, set the stage for a reevaluation of chronic fatigue syndrome,
fibromyalgia and Gulf War syndrome.
Now he's introducing XMRV to the allergy crowd. The fact that allergists are now
getting XMRV reviews shows the breadth of interest the virus has so quickly
generated. You can see Dr. Baraniuk's focus coming through as he rattles off a
list of symptoms common to ME/CFS that are not always noted in reviews of the topic; besides fatigue he
mentions non-allergic rhinitis,generalized hyperalgesia and allodynnia (pain), dyspnea (shortened breath)
without airway obstruction, drug intolerances, postural tachycardia syndrome and other
autonomic dysfunction syndromes.
Dr. Baraniuk's sentiments regarding ME/CFS are clear early on in the paper "the new finding of XMRV in CFS patients
must make us pause at these frustrated and disillusioned victims of medical neglect"! Strong words
indeed, that no doubt reflect Dr. Baraniuk's frustrations that getting funding for it (despite the
fact that he is one of the few researchers able to get NIH funding for it). When I
talked with him he evinced dismay at the lack of funding this disease million person plus disorder gets in the US.
This was an objective overview and he noted some questions about the virus. The virus's link to
prostate cancer, for instance, at least at this point, is believed to derive from 'androgen response elements'
in prostate cells that help to activate the virus. Because women don't have prostate
cells and the hormonal elements in their cells are differernt, if XMRV is going to be a major factor in this female dominated disorder then
researchers are going to have to find
estrogen or progesterone related factors (female hormonal factors) that turn on the virus. Thus
far Dr. Baraniuk says they haven't. (Dr. Mikovits, in one of her talks, stated that a wide array
of hormonal factors can turn on the virus. That information, however, has not been published yet.)
Dr. Baraniuk also elucidated just how remarkably similar the six strains
that have been sequenced have been with just 30 out of 30,000 nucleotides
differing - most of which occur in 'nontranslated regions' ie 'junk DNA'. This is DNA that doesn't affect the virus at all; thus with regards to
functioning, at least thus far, these strains appear to be completely identical. (The fact that only
six strains of the virus have been sequenced thus far should also give us a bit of
pause - that's hardly enough to give us
a representative sample. The fact that hey are from different parts of the United
States does suggest, however, that
this virus has evolved very little during that period of time it's been in humans.
XMRV's potential to cause cancer has been well noted but Dr. Baraniuk (thankfully to my mind) downgraded
this possibility stating that increased incidence of leukemia and lymphoma has not been
seen in CFS. (Of course, we're awaiting the publication of study from the Whittemore Peterson Institute that found an
increased incidence of lymphoma in Incline Village residents with CFS.)
Dr. Baraniuk closes with some intriguing questions: Is XMRV also infecting
the immune cells (microglia) in the central nervous system? If it is - could it be responsible for
the cognitive, autonomic nervous system (problems standing, bowel problems, heart problems, circulatory
problems) and pain processing problems in CFS and FM? Can it be detected in the
cerebral spinal fluid. (Dr. Baraniuk has cerebral spinal fluid sample from his prior studies - is he testing them?)
Are healthy people with the virus at risk of coming down with CFS or FM or prostate cancer?
Most interestingly,
Dr. Baraniuk clearly labels the strange fatigue states that occur after cancer, or in lupus or other diseases as 'CFS' - thus
broadening the disease greatly! - and asks if XMRV could play a role there as well.
Discuss the paper here.
- The "Quickie Studies" - we've had quite a dry spell study wise. The last
study - the Kuppenfeld Dutch study - came out about six weeks ago (Feb 25th)
Does this suggest that we're at the end of the 'quickie' studies that focused on
banked samples (some of them 20 years old!)? Let's look back...The first study,
the Erlwein study with Dr. Wessely and others has turned out to be notable for how
quickly it came out. The original Science study was epublished on Oct. 8th. The Imperial College researchers must
have jumped on it that night because less than two months later, on Jan 6th, they published the first follow-up study.
It took another five weeks for another study (Groom) to come out (Feb 15th) and then another 10 days for the Kuppenfeld
study to come out (Feb 25th). Now it's been six weeks of silence. It appears that the
quickie studies may be over..the next batch of researchers may be taking more time,
sharing samples, be doing more comprehensive testing or simply not getting
the greenlight from their publishers but this substantial lull suggests the next studies will be more substantial.
How will April turn out?
Will it be the 'cruellest month' (aka TS Eliot) or will it turn things around for XMRV? Or will it pass like
a mouse in night?
- XMRV Breaks Out - Whatever happens with CFS XMRV the is certainly
enjoying a day in the sun. Papers are coming in every week. Most of these appear
to be on the way before the CFS Science paper hit the press. The first XMRV
paper in 2009 took all the way until July to appear. Between July and October
three more papers appeared. In the six months since then 20 more papers have
appeared. Many more are certainly on the way - XMRV has become a minor hit in
the research world.

- Breakthrough in XMRV Testing
- We were told that the research community would be all over XMRV and they have
been but its still astonishing to see the speed with which they work. Five
months ago XMRV was an underappreciated virus that might
have some connection to prostate cancer.
Now papers are coming out steadily. Its nice to see what the research community
can come do when they find something they feel is important....but of course it
hurts too. One wonders where we would be if the research community had
portrayed even a fraction of the interest in ME/CFS that it has with XMRV. Of
course, the XMRV story is only at its beginning....if it plays a role in
prostate cancer or ME/CFS or the blood supply - hold onto your hats.
In any case a study by Dr. John Petros of Emory University suggests that a huge
step forward for prostate cancer patients with XMRV has been made. Researchers
have been painstakingly examining prostate cancer samples for XMRV. Now Dr.
Petros, using technology developed for finding HIV, reported that he has
developed an accurate and sensitive blood test (neutralizing antibody assay) for
XMRV that prostate cancer patients. That means if they have XMRV in their
prostate he can find it in their blood.
The finding was confirmed by two independent laboratories using PCR and "FISH".
Its hard to imagine that this test won't apply to CFS patients as well.
This is a strong finding that indicates that XMRV is indeed only the third infectious
retrovirus known to infect humans. It will surely continue to spur interest in the virus. The authors stated that
"our report adds to the growing body of evidence that XMRV is indeed a novel
gamma-retrovirus capable of infecting humans and that at least some patients
with prostate cancer have been infected with XMRV.

- Crunch Time for XMRV: Big XMRV Fed Study Ramps Up
- Courtesy of the Wall Street Journal we
finally got a look at what will surely be the most comprehensive XMRV study that
we'll see. It will surely clear up many of the questions surrounding the virus.
Its a full bore effort- one that probably only the federal government could take on.
Six labs will be involved; the Whitmore Peterson Institute, National Cancer Institute, the FDA, the
CDC and two others (not mentioned in the article). They'll be doing all the things that haven't been done
thus far; first they're sharing samples amongst themselves to determine which tests are the most sensitive and reliable.
Rather excitingly, the WSJ reports that that phase will be done in just a few weeks.
While they're doing that they'll also be testing about 350 samples of different types; some
will be from CFS patients who've have tested positive for XMRV, other samples will be spiked with
XMRV and others will be from healthy controls.
A Critical Factor: Importantly all the samples will be blinded; that is, the
the codes will be held at a central location while the different labs determine which samples they think
are
XMRV positive. The codes will be broken and the lab that has the best results wins the
'best diagnostic test' award! Blinding is the
most critical test to pass in this process; the first retroviral discovery in CFS lost its
way when blinding was introduced into the process.
The third phase - if XMRV shows up then the group will start going through frozen blood samples
from years past trying to figure out when XMRV entered the blood supply, what it's done to
people, etc.
A Solid Foundation - If XMRV can pass the 'blind test'; ie if one of the
labs can correctly identify samples with XMRV in them from samples without XMRV in them then XMRV can proceed on a solid
-
one would think unimpeachably solid - foundation. Simply finding it in a subset of CFS
patients, of course, would be a huge boost to the field. Money would presumably
pour in and ME/CFS would gain a legitimacy and recognition that it's never had.
Not finding it would also presumably end the search for XMRV.
Consider the worst-case scenario if XMRV is found: XMRV is found to
be simply a
passenger virus; it's just along for the ride - it doesn't appear to make CFS
patients worse - its just there. Just the fact that
it's there in ME/CFS patients but is not present in the same percentages in
healthy controls itself says something rather profound about the health and
immune systems of ME/CFS patients. Simply finding XMRV should lead to a greater
exploration of the viral and and recognition of the immune abnormalities of this
disorder. That alone could shift the scientific communities focus on CFS.
XMRV's
big test is upon it. There should be no worries about 'researcher bias'. Two
'friendly' labs, the WPI and the National Cancer Institute are involved. Neither
the WPI nor the NCI would have signed off on these studies unless they were
satisfied regarding methodology, blood handling and storage, patient cohorts,
etc. There were no time frames given; we know that they're already engaged in
these studies and some results should come in weeks but it's hard to tell when
the studies will be published. We assume that they'll be published as 'quickly'
as possible. Its clear, though, that crunch for the XMRV is coming.
April 5th
- Virologists Speak!
- Dr. Goff, one of the top retrovirologists in the field,
taked with Dr. Racaniello about XMRV for almost an hour. This was a rare
opportunity to hear what experts in the field felt about the XMRV/CFS
connection. Here's my take on what they said:
XMRV and the Prostate - One way researchers figure out which types of
cells a virus infects and which parts of the body it may damage is to determine
which cells have receptors for it. Receptors are like hooks the
virus can use to get into the cell and different cells will have different
receptors. Despite XMRV’s ability to grow in prostate cancer
cells they do not have high levels of the receptor XMRV it needs to
enter the cell. So why is it there? Because prostate cells
have a ‘transcription factor’ XMRV use to help it replicate - so
if it XMRV gets into a prostate cell there’s a good chance it can start
‘reproducing’. The researchers were surprised how vigorously
XMRV grows in prostate cancer cell lines.
In fact researchers have known of murine leukemia viruses - the
type of virus XMRV closely resembles - for quite some time but
they didn’t get much interest because once these viruses got into a cell they
generally didn’t do much; they were considered ‘weak viruses’.
That was before they attempted to culture in the cells they’re using now.
Interestingly XMRV doesn’t appear to do much in the immune cells it has been
found in CFS.
Cancer Virus or Not? - There’s been a
lot of speculation about XMRV’s ability to cause cancer given the
propensity of similar viruses to insert themselves in
areas of the genome populated by oncogenes - genes that can turn cells
cancerous. Dr. Goff said, though, that none of the
researchers that have looked at the ‘integration sites’ of XMRV in prostate
cells have found that it’s been inserted near an oncogene; XMRV’s cancer causing
properties are unclear.
XMRV Jumps Into People :
Given the remarkable similarity between XMRV and murine leukemia viruses
researchers have thought that XMRV must have ‘jumped’ into humans recently -
within the last couple of 1000 years. Dr. Goff said that the
various isolates of XMRV’ that have been found are ‘unbelievably similar to each
other’. He called that ‘very odd’ and stated that there’s something ‘funny about
its lack of evolution across a person or a group of people’. It could mean that replication is slow or not happening.
ME/CFS (chronic fatigue syndrome)
With regard to XMRV and ME/CFS he noted how “It looked very striking and
unbelievably exciting if you were in the field” and stated that with regard the
present situation
“All the signs look good and still do look good as far as one can see in the
(Science) paper but it’s also true that similar studies with even larger numbers
of CFS patients have been looked at….an they’re not seeing it”
He stated that slightly different strains occurring in Europe could be causing
the lack of results thus far noting that 1 bp difference is all you need to miss
a strain. He felt, though, that “The CFS connection is up in the air.” He didn’t
feel confident to vote one way or the other yet.
'Politics' - Dr. Raccinelli is obviously a bit perturbed at the WPI
rather aggressive defense of XMRV stating “The people that found
it are very vehement that it’s the cause and that everyone else doesn’t know how
to do PCR.”
Dr. Goff responded “Right, I think they’re at least adamant that the linkage is
real and they’re coming out pretty strongly about cause and I think that’s a
very touchy call to make at this point. There’s no way I would feel comfortable
claiming this is the cause of either prostate cancer or any other disease”.
Dr. Raccinelli also apparently wasn’t comfortable about statements regarding
unpublished findings stating
“I mean they claim to have data from all over the world implicating that the
virus in CFS but we haven’t seen that in the literature.” He apparently thought
WPI researchers should have been at the big retroviral conference in San
Francisco where XMRV was discussed asking “Were they at the meeting CROIX? “ The
answer was no but plenty of other conferences are coming up.
The Best Test? On a more positive note Dr. Goff acknowledged that when
viral loads are really low (as they appear to be in XMRV) that antibody tests
can be more effective at finding a virus than PCR tests -something Dr. Mikovits
has stated. Dr. Goff also noted that if antibody results are
positive they present a strong case for XMRV’s presence stating “It’s very
compelling if you do have seropositivity (antibody result) because then it’s not
a cause of contamination.”
How to resolve the different study results? Swap sample; he was amazed that had
not been done yet stating
“Some of us looking at those papers are amazed that they didn’t. I guess that
they’re just working very fast for one thing. They’re trying
to get stuff out quickly and they haven’t taken the time to swap samples.
So these studies that have reported zero recovery out of hundreds of
samples of course they did the positive controls of clones of the virus so they
know the PCR is working at that level but they haven’t taken true samples from
someone and shown they can recover it. That is happening now. “
XMRV’s Effects - He stated one team
had followed primates over a year; they found that XMRV levels peaked at one
week after infection, then declined to low levels for the rest of the year but
that they found it in a lot of tissues. It’s a real virus
…but whether it causes anything…any pathology…..we don’t know.
There’s no dramatic pathology yet.
It does not appear to kill human cells. One researcher says he thinks he can see
some subtle morphological changes in XMRV infected cells but you can’t look at
an XMRV infected cell and tell if it’s infected or not.
AZT: He said he would only take AZT
if he knew XMRV was rapidly replicating in him. (AZT attacks the virus during
replication; if the virus is not replicating much then AZT is not going to touch
it). At least in the blood we don’t have any evidence that XMRV is
replicating much. IIn fact it appears not to be replicating much.
Is it replicating elsewhere? No one knows.
He stated that in the next year we’re going to get a lot of information.

- Not a Drug for CFS?
- Raltegavir scored well in tests against XMRV (see
below) but IslandFinn in the Phoenix Rising Forums pointed out that Dr.
Racaniello's November blog suggested that Raltegavirs apparent ability to
exacerbate the auto-immune response means that it could be the wrong drug
for at least some CFS patients.
Check the blog out here.
April 3rd
- A Drug for XMRV? Raltegavir - Dr. Singh recently published a paper
examining the effectiveness of different drugs against XMRV
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0009948
Dr. Singh noted that few antiretroviral agents have been tested against
XMRV-like viruses and that the protein structures of HIV and XMRV differ so much
that it's difficult to predict which HIV targeted drugs might work for XMRV.
Dr. Singh took several drugs from each class of the known antiretroviral drugs
plus some that are still in the development stage as well as some antivirals,
put them into cultures of XMRV and then determined if they were able to inhibit
virus.
Of the 45 compounds tested four ‘strongly inhibited’ XMRV in cell cultures: RAL,
L-000870812, ZDV and TF. Because low doses of these compounds were
sufficient to significantly inhibit XMRV, Dr. Singh suggested patients might be
able to tolerate them well. The fact that combining the drugs
together enhanced their effectiveness suggested that ‘drug cocktails’ (aka AIDS)
might be a possibility. Raltegavir worked effectively in four
different types of cells and this was the drug Dr. Singh concentrated on.
Raltegavir (TF) - the first of a new
class of anti-retroviral drugs called ‘integrase inhibitors’, raltegavir was
approved to treat retroviral infections in October 2007. Integrase inhibitors
attack retroviruses after they have entered a cell and prevent them from
inserting their genetic material into the DNA of the cell. Because retroviruses
replicate by inserting their genetic material into a cells DNA, integrase
inhibitors could stop retroviral replication. Because XMRV’s possibly tumor
causing effects are believed to result from it’s propensity to insert itself
near ‘oncogenes’, Raltegavir could block this process as well.
Side effects - the most commonly reported side effects are
diarrhea, nausea and headache. Blood tests showed abnormally elevated levels of
a muscle enzyme—creatine kinase—in some patients. Isentress should be used with
caution by patients who are at an increased risk of muscle problems like
myopathy and rhabdomyolysis.
A Genetically Homogenous Virus AIDS
Treatment Efforts - Dr. Singh noted how genetically homogeneous XMRV appears
to be; the most distinct strains collected from distant parts of the US thus far
have differed in only 27 out of 8,100 nucleotides (!). This could be helpful for
XMRV infected patients because it suggests that XMRV replicates very slowly. If
the virus is staying ‘static’ then it’s not evolving to escape the effects of
whatever drugs are thrown at. This suggests that the possibility of drug
resistance to XMRV is probably much lower than for HIV and that the ‘drug
cocktails’ manufactured for virus might be simpler.
Anti-Herpes Drugs Do Not Work -
Several anti-herpes virus drugs (Foscarnet, Ribivarin, Acyclovir, Ganciclovir,
Vistide) were found not to be effective against XMRV. It’s unfortunate that she
did not test some of the herpesvirus drugs more commonly used in CFS
(Gangciclovir, Valaciclovir (Valtrex), valganciclovir (Valcyte)). However, the
finding that Vistide was not effective against XMRV, suggests that that XMRV may
not be a major factor in those patients who improved dramatically on Vistide.
Cooperative Diagnostics Drops Clinical Test for XMRV
- The CD XMRV test will
be only available to researchers henceforth.
April 1st
- Dr. Singh Talks.
Get your first glimpse of Dr. Singh in a short piece on
XMRV on ksl.com in Salt Lake City. Dr. Singh was a key figure in XMRV research
before ME/CFS showed up and as we recently noted she is embarking on a large
(and probably definitive) study on XMRV in CFS.
CBS on the Phoenix Rising Forums - is in the new Singh/Bateman/Light study - and he
had this to say
about Dr. Singh
"Dr. Singh is quickly becoming THE action on this. Dr. Bateman was exchanging
e-mail with her the day the Science article was published. Dr. Bateman has been
supplying her with a "well-defined" cohort of CFS patients. And Dr. Singh is
currently involved in a whole series of XMRV studies, each building on the
others. They are doing so much that would make absolutely no sense if all they
had were negative results. Lastly, it is a bit surreal to be watching Ed Yeates,
one of our local (for me) science reporters doing the story. I was writing the
local papers and TV stations every day to try and get some attention paid to the
Science article.
I've said this before but it bears repeating, Dr. Singh is at Huntsman Cancer
Institute (one of the best in the world) and ARUP (a huge specialty lab) and she
remains an adjusct prof at Columbia.

- Effective XMRV Treatments
In the Lab
- CFS Since 1998 on the Phoenix Rising Forums has
done a nice job of evaluating laboratory test results on treatments for
XMRV. Bear in mind that these are laboratory tests and that tests that are
effective in a test tube are not necessarily effective in the body.
Not Effective:
- 3TC (lamivudine; NRTI) [1,2]
- ddl (didanosine/Videx; NRTI) [2]
- d4T (stavudine/Zerit; NRTI) [1,2]
- ABC (abacavir/Ziagen; NRTI) [2]
- foscarnet [2]
- ritonavir (Norvir; PI) [1]
- saquinavir (PI) [1]
- indinavir (Crixivan; PI) [1]
- efavirenz (Sustiva/Stocrin; NNRTI) [1]
- nevirapine (Viramune; NNRTI) [1]
- 118-D-24 (integrase inhibitor) [1]
Effective:
- AZT (azidothymidine/zidovudine/Retrovir; NRTI) [1,2] *
- raltegravir (Isentress; integrase inhibitor) [2] **
Conflicting:
- TDF (tenofovir/Viread; NRTI) [1,2] ***
Notes:
*AZT inhibits XMRV at a similar concentration as HIV; 0.45microM versus
0.3microM [2].
**raltegravir inhibits XMRV at a similar but 2.5-fold
lower concentration than HIV; 0.82nM versus 2.25nM [2].
***TDF at a concentration of 30nM had minimal
inhibition of XMRV [1]. In another report, TDF inhibited XMRV at an IC50 similar
to but 3.9-fold higher than the IC50 of HIV; 1.48microM versus 0.38microM [2].

- WPI XMRV London Study -
this is looking more and more like a really interesting study. A
website has been created
for
the study participants. This is a very nice sized study (225 patients) of which
about half appear to be homebound - we'll get a good look at how XMRV shows up
in the severely ill subset of ME/CFS patients.
For a discussion on the study.
- Studies, Studies, Studies! - Interest in XMRV does
not appear to be flagging after the negative studies; we've had at least three
studies in the past week to the XMRV Studies page. We still have 20 studies we
think that are going on that haven't publish their results and there are
certainly more out there.
March 31th
- CFIDS Association Partners with Glaxo-Smith Kline to Study XMRV - The CFIDS
Association its new BioBank to work quickly. Just days after the BioBank was
announced Dr. Lapp reported that he, Dr. Bateman, Dr. Klimas and Dr. Gluckman
were providing
samples via the BioBank to the pharmaceutical company, Glaxo Smith Kline, to test for XMRV. The
CAA has been worried about patient cohorts since the beginning. Dr. Lapp stated
that the patients in the study will be as close as possible to the patients in
the original study. This is the first patient cohort of this type to
participate in a research study that we know about.
This is how the BioBank is supposed to work; the CAA provides the samples - thus
cutting down the cost of the research considerably - and the researcher simply
tests them. For more on
this click here.
March 27th
- ARUP - A 'Ripping' Good lab - Tom Kindlon must a ripping good memory as well because he pointed out
that the ARUP lab the Light/Bateman/Singh study is using has played a role in CFS before. In
fact it played a critical role in Dr. Chia's work with enteroviruses. "The CFS Patient Advocate"
is one of my favorite blogs; this is what he had to say about Dr. Chia and ARUP
"Dr. Chia discovered an antibody test for Coxsackie and Echoviruses that is more
specific than other labs. By serendipity, a sample from Dr. Chia’s office ended
up in ARUP lab in Salt Lake City - and the results came back quite
positive. Upon investigation, Dr. Chia discovered that this ARUP lab does a test
that is more specific than other labs. This ARUP test reports antibody levels of
Coxsackie B 1-6 and 5 of the 32 Echoviruses. An elevation of 1:320 (1:32) is
considered to be significant., especially for b4.
Look at how much more sensitive
ARUP's tests for enteroviruses were than another lab (same patient).
October 2009, at Focus Diagnostics
b1 1:16
b2 <1:8
b3 1:16
b4 1:16
b5 1:8
b6 1:8
October 2009, at ARUP labs
b1 <1:10
b2 1:320
b3 1:80
b4 >1:640
b5 1:10
b6 <1:10
By the other labs count - no infection; by ARUPS count - a massive infection. If
you've followed the enterovirus story you know that poor testing has made a huge
difference in that saga. Before ARUP Dr. Chia was having trouble proving enteroviruses were present in
his ME/CFS patients. He knew they were there because his treatments were having
effect but he had trouble proving it. After he stumbled on ARUP he was able to
prove it and this lead him to take the final step and do gut biopsies which nailed the
enterovirus infection.
ARUP is obviously a very sophisticated lab! Will it
play a seminal role with XMRV as well? We shall see. At the very least this is a lab, and
a group of researchers and a patient group whose
results we can obviously trust; a combination we haven't seen in any of the
validation studies.

- UK XMRV Participants Missing Something? - If you're one of the 225 people in
the UK XMRV study you might want to check your spam box. I just got this communication
from one of your compadres:
Some people that make up the
225 patients in the WPI's UK based XMRV study might not yet be aware that they
have had an Email from Ed Cutler at Phlebotomy Services International which has
been filtered out by their Spam software.Just
a note to make you aware that some people that make up the 225 patients in the
WPI's UK based XMRV study
I had a message waiting from him for
over a week and only became aware of it because I was browsing your message
boards (Phoenix Rising Forums) last night and came upon a message (posted by
ukxmrv I think) suggesting that we needed to check our spam box if we hadn't
heard anything yet."
- Six months until the WPI opens its doors....its been five months since the
XMRV Science paper...its just around the corner.
- Different Strains Effecting Results? - Mark on the Phoenix Rising Forums that
this interesting piece of information from the CDC. We know that the CDC is
doing a quite extensive study on XMRV but we haven't heard anything on it yet.
Here they report that a search for XMRV in prostate cancer patients didn't find
much but what they did find was genetically a bit different than has been found
before - which suggests that different strains of XMRV are floating around out
there. This suggests that the conclusion that XMRV is very homogeneous may not
be correct and leaves open the possibility that the current tests may not be
picking up all the strains. If XMRV is more genetically heterogeneous than
thought this would probably push back its 'entry date' quite a bit further than
the 40 years that's been proposed.
Walid Heneine of the CDC From the summary- "The finding of distinct XMRV
suggests that multiple strains may be circulating and shows a broader XMRV
diversity than currently known."

March 26th
- Light in the Darkness: Good News Ahead for XMRV?
- A month ago the head Dutch researcher, Kuppeveld, stated that he considered
XMRV story over. After what he described as an intense effort to find the virus
failed he was folding up shop on it; there would be no more XMRV studies coming
out of his lab.
No papers have been published since then but it appears that a decidedly
different story is brewing in Utah. We had heard that the three dozen or so
people who participated in the Light’s fascinating exercise study were brought
back to get tested for XMRV. What we didn’t know is that that study has recently
been expanded - greatly. Since one thing researchers do not do is repeat
negative studies, the only logical conclusion we can draw is that enough CFS
patients tested positive for XMRV to make a greatly expanded and obviously much
more expensive study worthwhile. These patients, and we don't know how many were
positive, appear to be the first patients who’ve tested positive at an
independent laboratory. The XMRV story may be over in Holland but it appears to
be gathering steam in Utah.
Luckily, CBS, a member of the Phoenix Rising Forums is participating in the new
study and was willing to give us some insights into what's happening. First the
new study consists of about 100 CFS patients, hand-picked by Dr. Bateman, and
about 200 healthy controls. Dr. Light appears to a major fundraiser for the
study - plucking money out of every corner he can. Dr. Singh, a noted
retrovirologist already steadying XMRV in prostate cancer, will supervise the
analysis of the samples. ARUP - the research laboratory associated with the
University of Utah - is providing facilities and manpower.
When CBS showed up for his blood draws he stepped into a highly professional
environment. He signed in and rounded the corner to find a hallway full of techs
with stopwatches. As each of approximately 6 vials of blood were drawn, the
gloved phlebotomist immediately handed it to a gloved tech who set his/her
stopwatch and hustled out of the room to the next location. The collecting
receptacles were swabbed with alcohol after each patient.
Dr. Bateman’s role in this is interesting. Her video presentation about
XMRV several months ago was notable for her sober approach to it is and she
appeared quite concerned about how well her patients matched up with the
apparently immune dysfunctional patients in the Science study. Although we can't
know for sure it appears that something has changed in her outlook on XMRV. She
stated that all parties were working around the clock on this.
These researchers moved fast - it took them about a week or two to process get
several hundred samples. They’re doing PCR, antibody and culture tests. CBS
expects to get his results in about eight weeks and the researchers are banking
blood as well - so expect more studies to follow this second study if it works
out well.
ARUP is
by no means an ordinary lab. Employing 2,400 people it is a ‘national reference
laboratory’ that specializes in ‘innovative laboratory research and development.
The website states that ARUP chooses to provide "highly complex and unique lab
tests" The Light/Bateman/Singh/ARUP team will not be looking at one sample
multiple times or testing multiple samples from one patient to get one positive
result. Nor will they accept ‘dim bands’ on the PCR as positives (a critique
given to the Science paper). This will be a one sample one patient, clearly
defined PCR result study, and logically this is what we should expect over time
as larger, more sophisticated labs further refine XMRV testing procedures.
Dr. Bateman is well known for
her well characterized patients and her fine-tuned sense of the different
subsets present in CFS and FM. She stated that she believed this study will
provide definitive evidence of how prevalent XMRV is in a broad swath of CFS
patients.
The Dr’s Light (there are two of them) role in this is intriguing as well. Dr.
Alan Light came up with the scintillating study that found greatly increased
receptor levels to substances like lactic acid in CFS patients. He is a pain
researcher, not a retrovirologist - but it appears that both he and his wife are
giving this study every kind of support that they can. We should be thankful for
researchers that are able to leap over professional boundaries when needed.
The Montoya-Goff Study - CBS is also the patient of Dr. Montoya’s. He
noted that Dr. Goff, another celebrated retrovirologist, is working with the
Montoya team in Stanford on his XMRV study - another sign that XMRV is still
alive and well in the research community, at least on this side of the Atlantic.
ARUP and Blood Testing -
Please do not try to get your blood tested at ARUP. Dr. Bateman emphasized that
ARUP is not open for commercial testing of XMRV and does not want to be flooded
with requests for that.
Conclusion - While we don’t
have any published papers we do appear to have the next best thing; signs that
several researchers associated with a reputable independent lab are having
success finding this virus in ME/CFS patients and, in fact, are redoubling their
efforts to look further.

- New XMRV Study Opens Up - Andreamarie on the Phoenix Rising Forums posted about
an XMRV study that just opened up.
Massachusetts General Hospital in Boston, MA is doing an XMRV study. I found out
about it through a doctor I saw last wk and had my blood drawn today. I was told
they are looking for people. I do not know exact criteria but they didn't ask
for a direct referral from doctor. I told them I had CFS.
I was told I'd get the results in a few months but it WOULD NOT go into my
hospital record. A staff member drew my blood and a fellow then asked me
questions about symptoms. He did make it clear that because a study was being
done it did not mean XMRV was the cause of CFS. He was very pleasant and
professional.
The doctor in charge is Dr. Donna Felsenstein but the person running the study
is Katie Mooney. The phone no is 617 724 0075

- Muddied Waters -
Patients in Action - Just a day after Parvofighter's findings cast doubt on the
findings of the Dutch study (see below) Kurt of the Phoenix Rising Forums
raised some questions about the original Science study. In January Dr. Mikovits
stated that XMRV's very low viral loads made it impossible for researchers who
didn't culture their samples to find the virus. She even intimated if that
they didn't want to find a virus. This, of course, threw everyone into an uproar
- the small old story was happening again; ME/CFS patients were getting screwed
by the medical establishment.
A close look at the original Science paper
indicated,however, that the WPI neither cultured nor activated
their samples before they did their
PCR tests. While patients (and others) have been bashing the validation studies over the
head for not following the WPI’s protocol it turns out that, at least in one
important area, they were following the WPI's protocol.
(If
they had activated or cultured their samples first they wouldn't
have been following the WPI's protocol. )
The question we seem to be left with is why it suddenly became necessary
to culture the samples first in order to find XMRV? Why was XMRV so easy to find
in the first group but is so difficult to find in the next? The first thing that leaps to mind is,
of course,
the makeup of that original patient cohort. Could they have been so sick that
they simply had much higher viral loads? It stands to mention that VIP Dx - the WPI’s licensed lab - abruptly shut
down for a month in January
One suspects that Dr. Vernon's focus on the makeup of that original is at
least partly due to the no-culture/culture shift that occurred. Her analysis of the original
cohort suggested that of the 32 CFS
patient samples she could get information on only 12 tested positive on more
than one assay (of four) and a third of those patients had been diagnosed with
cancer. All told 13 of the 67 positive patients appeared to have cancer. This
suggests this was a very sick group.
The
WPI, on the other hand, has said that no patients had lymphoma and that further information wouldn't
shed any light on XMRV. Annette Whittemore stated the
study participants were randomly plucked out of patient samples in the WPI’s
repository gathered from doctors across the US. Again we're at a conundrum.
Dr. Mikovits was clear that she believes that no further information on that
patient group it is needed and no more information will be forthcoming.
Kurt has brought forward another more disturbing possibility; that the
validation study resifults thus far are correct and that XMRV is not found in
CFS…but that something else is. In this scenario XMRV shows up in those original
uncultured samples and then disappears in later uncultured samples and then
appears to reappear in cultured samples because the culture process itself is
bringing something else out patient's blood that looks very much like XMRV.
Its based on the idea that culturing can cause endogenous retroviruses to
show up. This is a kind of ‘ inadvertent but possibly very lucky’ scenario in
which WPI researchers do, in fact, find an important factor in ME/CFS - just not the one
they were looking for. It’s all speculation at this point; with a new set of
studies reportedly about to hit the presses we should know more soon. XMRV
is at a fork right now; the path it ends up traveling down is wreathed in the fogs of the
future - hopefully they'll lift soon.
Follow the discussion here.
It bears mentioning that WPI researchers are still apparently finding
‘XMRV’ in high percentages of CFS samples but in low percentages of healthy
control samples. They are also sequencing new strains. There’s also the new
antibody test that is reportedly more specific to XMRV than any test before
which we believe the WPI is using. These tests are checks on the validity of the
original finding; they represent the kind of self policing that the scientific
community, if given the resources, is so good at doing.
-
Big Pharma, XMRV and CFS - Walter Anderson has done really a very good
article on CFS and XMRV for PharmaExec. He paints a very sympathetic picture of
the pllight and promise of CFS; the huge group of largely underserved and
ignored patients who really present a real gold mine for pharmaceutical
companies if only they can get the research community to figure out what's going
on. I loved that he called ME/CFS the only large 'orphan disease'; orphan
diseases by definition are diseases that strike so few people that further
research is done on them. Although ME/CFS strikes a lot of people it still gets
funded as if it was an 'orphan disease'. He also does quite a balanced job, I
believe, on XMRV.

March 22nd
- The Cohort Question AGAIN! - We've spent alot of time on that original
Science cohort, but they're not the only cohort involved. After digging deeper
into the cohort from the last Dutch study Parvofighter on the Phoenix Rising
Forums has uncovered some disquieting facts about them. We knew that they were
defined using the Oxford definition - which is not optimal, for sure - but not
necessarily a game changer but what Parvofighter uncovered goes beyond using a
poor definition.
The samples from that study were gathered a long
time ago - prior to the creation of the standard Fukuda criteria that
researchers use today. We're talking early in the recent history of CFS when
things were even foggier than they are today. Their symptom profile appears to
be an odd one; they were clearly ill but in significant ways they just don't
look like CFS patients. This is what they looked like.
Seventy-one percent had muscle pain - fine, but only 51% said they had
difficulty concentrating, headache, gastrointestinal complaints and dizziness
(?) were pretty common (@45%) which is good but only 43% had sleep disturbances. Both sleep problems and trouble concentrating seem to be present at
substantially lower percentages
than are usually found in CFS. Recurrent infections came in at a low 26% and sore
throat, one of the cardinal symptoms of the Fukuda definition is down at 13%.
Sore throat isn't believed to be as common in CFS as was once thought but its
still far more common than 13% in this cohort. Unfortunately postexertional
malaise was not part of the symptom picture at that point and we don't know
about that.
In short, while the group does have some similarities to CFS as we know it, in several significant ways this group does not seem very "CFS'ey" - a fact that could
certainly complicate a researchers ability to find XMRV in it. This was a study
that appeared to almost immediately put the nail in the coffin for XMRV for some
researchers but one wonders just how likely it was
that it was ever going to find much XMRV at all.
Check out the discussion here.

- One Test To Rule Them All
-
Several researchers have proposed that multiple labs do blinded tests of the same samples
in order to clear up the confusion. The blinded element is the key. The
DeFreitas retrovirus fell apart when it was subjected to the scrutiny of blinded
tests. After her first postive internal blinded test she was unable to replicate
the results in further public blinded tests. Neither was a lab that had
consistently reported that it was distinguishing CFS patients from healthy
controls using her test.
Yet a blinded test with several labs is probably the WPI's best chance at
turning this thing around quickly. If the WPI can accurately distinguish CFS
patients and healthy controls using their test while other labs cannot it's hard
to believe that the research world won't flock to them.
Doing blinded tests is tricky; for sure - with the high stakes involved they
require a certain level of trust and a standard protocol and, of course, a high
degree of coordination. During the DeFreitas era the CAA had the wherewithal to
create a blinded test scheme. Using Invest in ME's funding the WPI
and an independent lab are analysing the samples of
UK patients. Both labs will apparently be using the same
methods as in the original Science paper. Its unclear if they will be blinded or
not and given the fact that healthy controls are not part of the study that
issue diminishes somewhat in importance.
In the CAA's blinded trial of the DeFreitas test, the CFIDS
Association of America held the codes to all the samples. After the researchers
reported which samples were positive the CFIDS Association 'broke the code' and
identified who the CFS patients were. In that case about half of the positive
results were healthy controls - the test failed. The best blinded tests have a
third-party collect the samples (Invest in ME), identify which samples are from
the healthy controls and from the CFS patients and then give them all to the two
labs. We assume that the DHHS study must involve doing blinded tests using
multiple labs but they're moving very slowly. Blinded tests are the gold
standard of the research world. Hopefully someone is doing them. (This
is from a blog I wrote -to read more of the blog, click here.
March 20th
- WPI Back In Science - The WPI is going back to where it all started approximately 5 months ago -
the Science Journal. On their Facebook site the WPI just announced that Dr. Mikovits will address
some of the questions about the original study in the upcoming print edition of Science. The patient cohort and methods will probably be addressed. WPI has said that the patients
in the study were randomly chosen from a patient database filled with samples from various doctors
across the country but it appears that they and/or Science (probably both!) want to make sure
that the research community gets it. One would imagine they would also address later statements
that they had to search for the virus multiple times in time and space (using different samples
from the same patient) in order to find it in some patients. That statement was made after the
Science paper came out as one explanation for the difficulty finding the virus in another
studies. It will probably, I imagine, also address the effort made in finding the virus in
the healthy controls. One hopes it will address why the WPI believes that culturing is required. In
any case one can only believe that this is a positive move that will reassure the research community
and assist them in their work to validate the WPI's results.
- What is this big beautiful building
emerging out of the construction? What else but the future site of the
Whittemore-Peterson NeuroImmune Institute. Somewhere in there the WPI will be
housed....in just six months.
March 19th
- The Buzz is Back! We were down for about 10 days because of website
problems but the problem is fixed and the Buzz is back :).
- 85% positive rates (!). - Dr. Mikovits reported in notes for an upcoming talk in
Chicago at Autism One the WPI was getting 85% positive rates in 200 patients it
had tested. This did, of course,
throw the PR Forums participants in a tizzy. Just which patients was she talking
about? We have the original 100 or so patients in the Science. We know that
almost all of them tested positive to at least one test for XMRV. And we have
Vincent Lombardi of VIP Dx reporting 36% positive rates with about 300 patients
from VIP Dx.
The number appears to be from ongoing studies at the
WPI. Luckily someone on the boards is taking part in the studies and she
reported that they're usiing the new serology (antibodies) test (developed by
Dr. Singh?). 85% is quite close to the almost 100% for the original Science
group and siggests high positive rates continue when multiple tests are used. Of
course we don't anything about the selection process but given the WPI's latest
statements one would suspect these are simply ME/CFS patients.
Our contact reports this about the study she is in:
The
study I am in with WPI has included over 100 people. This study is testing not
only ME/CFS patients, but many other conditions and includes healthy staff,
family members and others. I don't think it is always clear when just ME/CFS
patients are being talked about and when more inclusive criteria is being used.
So far in my study, we have the results of only 20 tests (WPI is planning to run
all 4 testing methods on each blood sample), and 11 have been positive by
serology. I don't know how many of the 11 positives were healthy, but I do know
that the percentage was higher than the expected 3.8% which is causing a bit of
concern."
The Autism-CFS connection on the face of it is a strange one. How can one
relate often severely socially and terribly cognitively impaired autism patients to ME/CFS patients? Apparently
by looking at study results; Dr. Mikovits reported that both groups share
"immune dysregulation, increased oxidative stress, increased expression of
proinflammatory cytokines and chemokines, mitochondrial dysfunction and chronic
active microbial infections". One wonders if
different but somewhat similar immune dysfunctions can, by targeting different
areas, have quite different results.
Shining A Light on the Autism ME/CFS Connection - in an
email to a researcher, a couple of months ago, Dr. Mikovits agreed that it
probably would have better for her not to mention unpublished results about
finding XMRV in autism patients. It sounds like a paper is in sight now,
though, as the
document states that she will "show
evidence of XMRV infection in ASD and discuss the implications of XMRV infection
in the pathogenesis of neuroimmune disease including ASD".
If some researchers are worried about the status of XMRV Dr. Mikovits is clearly
not and she's moving boldly forward into one of the most contentious research
areas of all. The autism crowd is organized and active and they want answers.
Could XMRV be one of them?
The Conference is May 29th.
- Dr. Mikovits with the Patients
- Dr. Mikovits may have done more work to
indicate with individual patients over the past three months than any researcher
position probably has for years. The emails keep coming in. Someone on the Phoenix
Rising Forums just posted an interesting e-mail from Dr. Mikovits.
False Negatives - If you're getting tested at VIP Dx and you're still negative - even
after the new testing procedures when in - you're still not a solid negative. Dr.
Mikovits stated that only tests done at research labs are definitive right now. Of course
if, as she's stated before, if you're positive anywhere then you're positive.
A new, very fast test on the horizon? Dr. Mikovits dropped this
line in an email suggesting that a very fast, very sensitive test could be on
its way "We
may very soon have a very high throughput sensitive test for XMRV where we could
easily do 200 in a week!". In the midst of all this controversy about not
finding XMRV its good news that the WPI is continuing to refine their tests.
XMRV is to CFS as HIV is to AIDS? - that's the theory the WPI is testing right now. We know
that many people who are infected with HIV take many years to become ill and a select lucky few
don't become ill at all. Interestingly, Dr. Mikovits said that "But by definition if you have ME you must have XMRV." -
a very strong statement indeed!".
She also opened the door for different variants of XMRV to be present - an interesting idea
given the difficulty so far of finding the virus in other studies. Could the XMRV in the UK
be slightly different from the XMRV in the US?. Since the virus thus, far, has been remarkably homogeneous
genetically one wouldn't think so. Some of the studies have focused on very conservative
sections of the genome, as well - ones that are not likely to change
in any variant. Then again, one would hardly think that the first samples of
XMRV the WPI gathered would be representative of the population at large. Will XMRV throw
us a loop and be more genetically diverse than we thought? Could there be genetic variants in the UK and
elsewhere? The WPI is sequencing more strains of XMRV
and they are reporting increased diversity.
Check -
Dr. Mikovits also stated that "Maybe the reason others don't find it is because they will not do the BIOLOGICAL VIROLOGY and ISOLATE THE VIRUS like the WPI and VIPDx have done.
NO ONE else has even ATTEMPTED the experiments in the Science paper. Electron micrographs
don't lie..and a budding virus or immune response cannot be a contaminant..". It
would be interesting for the UK or Dutch researchers to explain away the immune
response. You can't apparently, drop a virus into a test tube of blood and have
the immune system react to it. For one thing - there's are no immune organs to
produce the B-cells that produce the antibodies the antibody test is looking
for. The antibody test is a check on the PCR test; the fact that the WPI was
able to show antibodies were present was an important validation for the Science
journals editors. The fact that they were able to grow a virus was another
check. At some point you get to the point where its seems statistically unlikely
or very (ie very, very unlucky) that all these checks would fail.
Check, Check, Check - Could the antibody test be wrong? The antibody test was
not specific to XMRV. which means that it could be reacting
to another mouse virus or perhaps some other entity. I've been told that its possible that the culturing process with
the hormones also could have activated an endogenous retrovirus that looked like a
retrovirus. But how likely is it that both of these
occurred? Then you have the PCR checkpoint the paper passed. Basically it seems that you have to have
a series of very unlucky incidents occur for XMRV not to work out.
Another check are the ongoing studies the WPI is involved in.If contamination was present the
WPI should immediately know about it because
XMRV would be showing up in both patients and controls in equal numbers and that doesn't seem to be happening.
Percentage positive rates have apparently not dropped markedly (check) and and healthy controls aren't all testing positive
for XMRV (check); that's all good news for the WPI and XMRV.
On the other
hand we have 3 studies that have been unable to find the virus. Since each used
different techniques each study constitutes another check on the WPI's results.Even if these are just
validation not replication studies what are the
odds that each of the studies made just the right type of 'mistake' that stopped XMRV
does not show up? They're not good either. Its a confounding situation either way.
For more of her e-mail.
- Dr. Enlander and ESME on XMRV - Apparently on behalf of the ESME group Dr.
Enlander posted a communication on XMRV. It was quite critical of the recent
studies stating
"These groups have rushed to publish unsatisfactory comparative research with
anecdotal results, based on small number of
ll-defined patients,
stale specimens and differing research methods" I don't get the 'small
number" criticism or the 'anecdotal report' criticism but, of course. there have
been questions about the rest. Dr. Enlander put himself is a bit of a strange
position here because he's been working with Dr. Kerr on another XMRV study.
Since Dr. Kerr played a key role in one of the 'unsatisfactory' studies Dr.
Enlander ended up indirectly critiquing his own partner. Some of Dr. Enlander's
patients have reported that he's said that Dr. Kerr has not found any positives in
his latest study. Which brings us to...
- Dr. Kerr's Latest Study - Dr. Kerr was apparently engaged in two XMRV studies
and was about to be engaged in a third study
when he returned the funding for it. While it's still not entirely clear what's
going on - Invest in ME is apparently not interested in clearing this matter up
- my conjecture is that Dr. Kerr has finished (?) the second study (with Dr.
Enlander) and failed to find any XMRV. Because the third study was going analyze
immune functioning in XMRV positive and XMRV negative patients and he didn't
have any XMRV positive patients he canceled third study. We don't
the answer to the all-important question - which methods he used in to look for
XMRV. We'll know, if and when, Dr. Kerr
publishes.
- Chief of HIV Unit to Head Up XMRV Study in Spain
- A top Spanish
retrovirologist is heading up a new study on XMRV in Spain. Claraverde, a
prominent ME/CFS advocate in Spain is asking for
donations.
- Dr. Sandra Ruscetti -
will be a keynote speaker at a Retrovirology Conference at Cold Harbor.
Dr. Ruscetti is an expert in mouse retroviruses and played an important role,
with her husband, in the WPI's work on XMRV. The fact that she's a keynote
speaker speaks to the kind of talent Dr. Mikovits gathered around her for the
XMRV work.
- Andrea Whittemore's Poscard Project - As a birthday present to her mother,
Andrea Whittemore has created a 'Postcard Project' to send postcards, letters,
photo's, etc. for a scrapbook for Annette on her birthday in April.
"
Let's remind Annette that our children, parents,
best friends, and other relatives will all be positively affect by our return to
good health. From now until April 16, please send thank yous to Annette in the
form of postcards, letters or cards from you and your loved ones. Consider
having your children draw pictures. Please send photos of you and your family
members if you can. If you prefer to send only your own thanks as a patient, we
are so happy to have that as well. I plan to place all we receive in scrapbooks
(nothing too fancy - just a way of keeping things together). Her birthday is
April 26, so please send it in ASAP to: The Family Tree Project c/o Heidi Bauer
3204 Cambridge Drive Huntingtown, MD 20639"

March 9th
- British Medical Journal Podcast on XMRV - It is XMRV month at the
British medical Journal and they devoted their podcast to it. First they had on
the controversial but always glib Dr. Wesseley. He eschewed a psychological approach to the
illness and instead focused on 'management' or 'rehabilitation'. Of course, we
weren't going to get any plugs for antiviral treatments or anything like that
but his management approach: getting away from the push/crash cycle of overdoing
it and then crashing, focusing on sleep, etc.. at least as presented here,
seemed very mainstream if obviously limited. The one interesting moment to me came when he
noted that while many pathogens can trigger CFS Epstein-Barr virus appears to
be particularly apt at doing so and he stated they didn't really know why that
was. He noted that in a 50 years or so our approach to this illness may seem
very primitive indeed.
Dutch Researcher: the highlight of the podcast was the appearance of the
Dutch researcher leading the last XMRV study. He noted that because he was
studying sporadic cases of ME/CFS that his results might not fit 'cluster' cases
described in the original Science paper (see below). He stated that they used
very high sensitivity PCR's - the same PCR's that the WPI researchers used - and
that they looked again and again for the virus and really challenged themselves
to find it. Because a fellow faculty member was actually studying XMRV in
prostate cancer they had positive XMRV samples they could use to ensure that
they could find the virus but, of course, as we know now they were unable to.
The most striking thing about his talk was the fact that he'd heard that a good
virologist in the US had been unable to find the virus as well. He believed that
the original finding was probably either due to contamination in the lab
or to the fact that the original group was from a cluster. (WPI has said they
were not from a cluster.) He believes that problems in chronic fatigue syndrome
are rooted in the neurobiology in the brain, and that's where his research focus
is.
Epidemiology - Next up was an epidemiologist who noted the
epidemiological deficiencies in the Science paper. These are pretty well known
now and not really worth going over; few papers are perfect - if the
epidemiological part of the Science paper had some flaws then sobeit. Her
analysis indicated, however, closely these papers are looked at. The Science
paper stated that the patients came from areas where there have been clusters or
'outbreaks'. It seems pretty clear now that while some of these patients may
have come from areas where there have been outbreaks at one time, there is no indication that these
patients were the victim of 'outbreaks'. If they had been, however, that could
have clearly made a difference because it's certainly possible that people who
come down with ME/CFS as the result of an outbreak could have a different kind
of CFS than people who didn't.
(That does not seem to have been the case here; the patients came from several
different physicians across US. Annette Whittemore noted that they were randomly
picked out of the WPI biobank.)
-
Phoenix Rising Forum Participants Report Low Positive XMRV Rates From their
Physicians - these are all anecdotal, of course, and they don't really
fit our polling numbers on the forums, but one forum participant stated that Dr.
Levine told her that of 11 patients only one had come back positive for XMRV.
None of Dr. Enlander's patients had apparently come back positive either but
they were being tested by Dr. Kerr not by VIP Dx. According to Dr.
Enlander's website that paper is being submitted for publication; it appears we
have another negative study result coming up. The polling numbers of the forums
are about 50% for VIP Dx.
March 8th
- XMRV Making Waves -
XMRV may be temporarily be underperforming in chronic fatigue
syndrome but it's doing quite well elsewhere in the research world. A report in
MedPage Today indicates that the virus appears to be transmitted much the same
way HIV is - through the blood and semen. At a Genitourinary Cancers Symposium (
once again in San Francisco) Dr. Klein (once again at the Cleveland clinic)
reported that semen has factors in it that dramatically (unfortunately) enhance
the ability of the virus to infect cells. He noted that HIV works the same way.
Like other murine retroviruses XMRV also appears to integrate itself into genes that
are related to tumor progression and metastasis. The work did suggest that anti-androgen (ie anti-
steroid hormones like cortisol) substances do inhibit XMRV replication.
March 5rd
- BMJ on XMRV
- citing the 'lively' response to their publication of a recent editorial on
CFS, the British Medical Journal did what any media outlet would do
when confronted with a hot story; they put XMRV on the front page of their journal
and packed the Journal with XMRV articles; this was XMRV month at the BMJ. Lively was
indeed the word
for the 30 odd responses the Journal received, many of them lengthy and most of them
taking the Journal to task for another behavioral, CBT promoting editorial on CFS.
The UK is as we know ground zero for the behavioral interpretation of ME/CFS The polite but condescending PR speak was, of course, present....the
concern over the patients....blah, blah, blah. They noted, which we have heard, their
concern over the patient cohort and the controls and the fact that their (and
everyone else's) attempts
at getting more information from the WPI failed. They went over the negative results and then
admitted that they had rushed the last paper through to publication; a paper that in some
respects, failed their standards. (An rather odd
revelation from a paper called "Let's Proceed with Caution") They closed
the piece in a rather snarky way appealing for research that this time, will be good enough.
(No one beats the British at the velvet gloved knife in the back :)).
March 5rd
- Dr. Kerr Backs Out of XMRV Study
- in surprise announcement Invest in ME announced that Dr. Kerr has backed out
of study Invest in ME was planning to fund on natural killer cell functioning
and XMRV. Dr. Kerr was a member of the second study not to
find XMRV in ME/CFS.
A person on the Phoenix Rising Forums reported that
Dr. Kerr was planning to use the positive samples from the first study for the
NK study but didn't have positive samples so the study was nixed. If
that's true it puts an entirely different spin on a story that seemed, based on
the initial information from Invest in ME, that Dr. Kerr simply didn't
believe XMRV was present in the UK. Hopefully Invest in ME will clear this
situation up. Dr. Kerr is currently collaborating with the WPI on a
multi-year study
examining novel pathogens and immune functioning in ME/CFS.
Invest in ME, is still committed to exploring XMRV's role in CFS and will contribute the money gathered for the study to the Whittemore Peterson Institute.
- WPI to do UK XMRV Study - A participant in the WPI's Facebook site
reported Dr. Mikovits sent her an email stating:
"We are having an independent phlebotomy company
draw samples in the UK in the next two weeks if you or others would like to
participate send me your addresses and contact info ASAP. samples will be split
and shipped half to an independent trustworthy lab and half to the WPI to
determine XMRV status exactly as in the WPI Science study.
Those who would wish to join this UK study please send your contact details to
judym@wpinstitute.org. asap :-)
March 3rd
- CFIDS Associations says Four XMRV Studies Not Enough
- The CFIDS
Association released a statement today stating that four studies aren't nearly
enough to understand XMRV's connection to CFS. They acknowledged the frustration
present after these studies but they also defended their critical analysis
of XMRV and other studies stating that challenging study design, methods, etc. is
is a vital part of the march of science which, of course, it is. At its best the
scientific endeavor is like thrusting a piece of ore into the fire, chipping and
burning away its impurities until it emerges, purified, with diamond-like
hardness. The WPI has not yet commented on the
latest study and the CAA also warned that they may not continue to comment on
every negative study that comes out.
After the abuse the organization
got on their website and elsewhere for last analysis of the XMRV finding, this
is hardly a surprise. A vocal minority of patients greets any negative
assessment of XMRV as being something that borders on 'traitorous'. One blogger
was so irked that somehow she managed to turn a critique of the XMRV study into
a claim that the CAA was supportive of Dr. Wessely's efforts. Never mind the
fact that the organization has never funded a CBT program and has easily funded
more research on viral pathogenesis than any other support organization - in a
heated environment like this the facts hardly count. It's difficult if not
impossible for any support organization to comment critically and responsibly in
an environment like this. Better to just bow out of the situation.
Unfortunately doing that
leaves the rest of us without one of the few informed voices we have. Few
organizations, in fact, have dared to offer their analyses of the situation and
the ME Association -which has its concerns about XMRV - has received similar (if
less virulent) responses. We've heard virtually nothing from the
IACFS/ME or MERUK or other organizations probably because they know what to
expect. For more on the CAA's
statement click here.

March 1st
- Third Time Not the Charm - I recently posted a blog on the Dutch XMRV study results and
a few other XMRV issues.
- Serology Test
Results Starting To Come In - A participant in the Phoenix Rising Forums recently posted that she
recieved her antibodies test result from Gordon Medical Associates (medical group working with the WPI). The test is
not available to the public (she's part of a study) but this indicates it could be available fairly soon.
My understanding that Dr. Mikovits believes this is, more or less, the
definitive test for the virus. She has reported on several patients who
were negative for the virus using PCR who were positve using the antibody test.
I believe she's been working with or is in collaboration with Dr. Singh in Utah
on the test. Dr. Mikovits also said that the author of the big prostate cancer
study that found no XMRV in Germany is rechecking his samples using this test.
Below is the
note this patient got from Gordon Medical Associates.
I know you have been anxiously awaiting your XMRV results. We finally got a
few initial WPI results, and your serology has come back positive. I think you
know that serology does not necessarily indicate active infection. We don't yet
have the other three test results for you, but they are being run.. . . We don't
know yet what to do about it. Dr. Mikovits assures me that everyone who is
positive will be given the opportunity to participate in further trials. We are
taking this quite seriously, and we will be looking for what, beyond what we
already do, would be most helpful.
You are free to share your results, but people should know that we got very few
results
in so far. Some were control samples we sent in, so we don't have many patient
results. They will continue to come in over time. Dr. Mikovits has been so busy
speaking that it has been hard to do the testing. The speaking is good, because
it brings awareness and money, so we need to be patient for the next step, but
at least you have the beginnings of an answer for yourself.
Check out the discussion here.
- Another Licensed Lab for XMRV Testing? - Forum participants also reported
that RedLabs is working with the WPI to develop testing using their same
procedures.
- National Cancer
Institute News - Dr. Sandy Ruscetti was, if I remember correctly, a
co-author (with her husband) of the Science paper. (She is also the head
of the Retrovirological Pathology Division (Cancer section). She's a key person
in the field as she's been studying how mouse retroviruses (like XMRV) cause
neurological disorders and cancer in mice for years before XMRV poppped on the
scene. She's now applying that knowledge to XMRV. On her NCI website she reports
that she is developing a rodent model for XMRV that will allow researchers to
test the efficacy of drugs against the virus.
Most interestingly she's examining how XMRV could cause its effects given it's lack of replication
and low viral loads in the cells in the blood. She believes the proteins that virally infected
cells put on their surface to indicate to the immune system that they're
(in effect saying 'please kill me')are triggering an aberrant immune response that may be
producing an neurotoxin.
Dr. Mikovits connection with the Ruscetti's is so intriguing. What is the statistical chance that
she would leave the employ of Dr. Ruscetti at the NCI and hook onto a mysterious virus in ME/CFS
patients that would turn out to be Dr. Ruscetti's wifes speciality. It's unbelievable. If
XMRV works out Dr. Mikovits was the perfect person to find it.

sometime after receiving a blood transfusion. Simply fill out their research
questionnaire and put blood transfusion in the applicable box.

- Third Time Is Not the Charm - Dutch XMRV Study Comes Up Negative
- A
small study found zero evidence of XMRV in chronic fatigue syndrome patients.
This was undoubtedly the weakest study of the bunch; it used quite old samples
and a watered down criteria and it involved a researcher reportedly committed to
cognitive behavioral therapy. The furthest thing from a replication attempt an
editorial accompanying paper nevertheless asserted that the methods should have
been sufficient to detect the virus if it was there.
All of the early
"quickie" studies appear to have their problems. Could those problems all amount to 'zero
results'? We'll know when more comprehensive studies come out. We're
still waiting for a study from the US. Dr. Mikovits stated that she expects some
National Cancer Institute studies to be out shortly.
Dr. Goff, someone
associated with the process since the original paper, stated on
Dr. Racanielo's blog that what's needed
now is for different labs to test the same samples; that is, labs should find
people who tested positive for XMRV via WPI or VIP Dx and test them. The CDC is
reportedly doing this now.
The WPI has not responded yet but it
seems likely they'll simply state that unless someone follows their is
procedures they are not going to find the virus. Dr. Mikovits reported that
she's not worried about these validation attempts; as soon as someone uses the
WPI's methods she expects they'll get the same results - time will tell.
Check out a discussion here.
The ME Association believes this third study considerably darkens XMRV's
potential for being a major factor in chronic fatigue syndrome stating "these
three negative studies now place a very serious question mark over the
proposition that XMRV is present in a significant proportion of the ME/CFS
population and that the infection plays a significant role in most cases of
sporadic ME/CFS." With regards the different procedures used by the different
studies they stated "the various laboratory investigations for finding XMRV have
been carried out in very reputable microbiological
research centres and involved retrovirologists of
international repute."
They believe the
problem lies not in different cohorts or different geographical spread of the
virus but in the laboratories doing the testing and urged that the same samples
be sent to and tested by the variety of different lands. They also
stated that "the MEA Ramsay Research Fund is very willing to consider funding
high quality research proposals".
Whereas they may at times take some flak for doing so both the ME
Association and the CFIDS Association of America should be acknowledged for
their willingness provide their analysis of what's going on to the patient
population while other groups (MERUK?, IACFS/ME) have hung back. Remarkably, the
our professional research organization (IACFS/ME) has contributed little or
nothing to the discussion on XMRV.
Ongoing 'Study' Continues to Find XMRV - one fact that is not being mentioned is
that one group has been and continues to find XMRV - daily - that's the VIP Dx
labs.
I
had heard that VIP Dx shut down because they couldn't find the virus anymore
-which suggested that it was a contaminant and that the contamination had been
cleared up; ie no more XMRV. So I asked them about that and this is what they
said.
Of course we have to bear in mind that one laboratory - VIP Dx - is finding XMRV
all the time. I had heard that they were no longer able to find XMRV using PCR
so I asked them. This is their answer.
There is so much MIS INFORMATION. In no way did VIP Dx stop testing for XMRV
using PCR. The culture is done by a PCR method. We streamlined the testing to
avoid the high costs that doing both the first run PCR and then the extraction
and culture had. We still extract and then grow cells for culture and run the
culture test. By streamlining our processes, we have developed a test method
that gives higher sensitivity at a cost savings that has been passed on to our
patients. Our license agreement with WPI includes consultations and quality
assurance by their researchers that we are running the best and most sensitive
test available at this time. This high sensitivity method is
producing good results in detecting
the virus.

- The CFIDS Association webinar
on its research program is up on YouTube. There wasn't much on XMRV, of
course, but it was fascinating look at what is turning out to be a very
innovative research program. It was a nice break from all the turmoil
surrounding XMRV. You can find it
here.
- Dr. Mikovits has been answering emails and she answered one of mine.
We heard rumors that the CDC was up at the WPI- that was untrue but the WPI has
shared it's reagants and antibodies, etc. with them. The CDC is apparently
contacting other labs as well for their specimens and doing extensive testing.
Dr. Mikovits reported that the vaunted DHHS study is still, 3 months later, in the 'design phase',
which hardly suggests the government feels any urgency about it. Other agencies within the govt. are moving
quickly. The CDC is acting on its own and Dr. Mikovits reported that she expects the NCI
(National Cancer Institute) to PUBLISH SEVERAL PAPERS SOON both on XMRV in CFS
and prostate cancer. Dr. Mikovits, of course,
hails from the NCI.
In her email she seemed both a bit exasperated and confident stating
"we don't lose much sleep worrying about replication, we are certain that once someone tries to do
it as in Science paper (they) will find it". The UK researchers didn't communicate with Dr.
Mikovits or the WPI but its hard to imagine that she's not in touch with her former
colleagues at the NCI researchers - given that her confidence is a good sign
perhaps some positive papers are on the horizon. She also said that the "HIV docs
get it 100%"
The WPI has been questioned a bit for putting a test out so early. Dr. Mikovits clearly stated
that the appearance of the Cooperative Diagnostics test, just a week after the paper came
osiut, pushed them to bring out a test earlier than they had planned. She said they asked them to
cease and desist and they refused. CD has its proponents; a member of the Forums has been in
touch with them extensively -and is impressed with their work; only time will tell how the CD situation shakes out.
She also stated that based on their facts so far it seems that XMRV is more prevalent in
the western US than the eastern US. The fact the XMRV samples were so genetically was suspicious as that can
imply they originated from one source (a contaminant) at the WPI or the Cleveland Clinic's One theory posits that a particularly powerful sample of XMRV could have escaped contaminating the lab and
the CFS samples (but somehow not the healthy controls?) or that the problem originated at the
Cleveland Clinic. Dr. Mikovits said, however, they now had 200 strains isolated and they're
sequencing them and finding more variation than in the first six.
Feb 22nd
- More From the San Francisco Retroviral Conference - The Forum participants
are continuing to dig up more info on how XMRV fared at the big (apparently one
of the biggest) retroviral conference in San Francisco.
Emory University is apparently big in hunt for XMRV. We know that XMRV is able to infect
cells called fibroblasts in the prostate but that epithelial cells express
a lot of antigens (markers on their surface suggesting that they are infected) as well.
Dr. Mikovits talked about an amino acid 'loop' that XRMV used to gain entry into cells. This team showed that
fibroblasts had this loop but the other cells - which appeared to be infected - didn't, which suggested to them
that XMRV has more than one way to get into a cell. What's so interesting about these other
cells? They happen to be smooth muscle cells; these are cells that dot the linings
of our blood vessels and tell them to open up or constrict. Researchers have conjectured
the blood vessel problems could cause many of the abnormalities in the brain and elsewhere
in CFS - an intriguing idea given that XMRV can apparently infect them.
This group is also looking at RNase L. RNase L has not appeared at these early stages
to determine IF one is infected but thiese researchers believe it could determine
which cells are infected.
There's much more coming from the conference. This conference and the months
ahead are clearly going to be head turners for all of us - not just in the
things that are learned - but in how quickly they are learned. It looks like
we're going to see what scientific community can do about an issue it wants to
study. It may be that we'll know more about XMRV over the next year or two that
we know about chronic fatigue syndrome - a sad even tragic statement in one way but a promising one in another.
Stay tuned.

- Complete Mikovits-Cheney Transcripts Available
- it was an interesting if partly inaudible talk
but the transcribers on the Phoenix Rising Forums somehow cut through the interference to produce a clean
copy. You can find
the first half here
and the
second half here.
- San Francisco Retrovirus
Conference XMRV Updates - XMRV infection in primates has thus far not
produced any visible symptoms - no fevers - no real suggestion of an infection.
Abbott Diagnostic researchers (not the Abt association with the CDC) have
developed antibodies to various proteins on XMRV and have been able to detect
them in humans but in only a very few of them (3/2851 blood samples) - which
doesn't nearly, of course, reflect the 4% prevalence in healthy controls in the
WPI study or the 1.5% prevalence in the Japanese study. Dr. Hackett noted that
could reflect the virus's life cycle (was is hidden?) or the time between
infection and disease or other factors. (These may be the viral reservoirs Dr.
Mikovits was talking about.) ifAbbott Diagnostics has been interested
in developing a diagnostic test for XMRV for about three years.
Neither Dr.
Coffin and Dr. Goff are jumping ship after the two negative studies; they've seen the ups and downs of
retroviral research before.
Dr. Coffin, in fact, appears to be an enthusiastic about XMRV as ever stating
"There is no
question I think that the virus is real and that the virus is infecting some
numbers of people. And it’s VERY (Coffin's emphasis) important to figure
out where it is going as far as all of its disease associations are concerned… it’s very early days… if you think back to 1983 and
what it was like with HIV, how uncertain things are, how long it really takes to
grind the sausage (!
) and come to a consensus to understand what’s really
going on…We’re still in a pre-consensus stage with this
virus, and although it’s annoying and confusing, it’s really exciting."
From Dr Goff: “We know very little about its mode of transmission. We
don’t have any reason yet to be excited about any pathology but it’s
certainly something we want to pay attention to and make sure we’re not missing
anything.
... And so we live as humans with a lot of viruses that are non-pathogenic or
that are not detrimental to the population… ( think people want to know a lot of
simple things. It would be great to know the origin – if it was a mouse…We’d
love to know the tissues in which it replicates, and we know a little about that
now because we’ve studied the virus in culture....the most important maybe is
the prevalence in the human population, which we don’t know….
Interviewer: Are there any other colleagues working on this, or is there
some sense of urgency, or just casually looking at it…
Goff: The NCI is pretty serious about it, they don’t want to miss
anything. And they want to play a role in identifying the properties of this
virus and its potential risks. So they’re pretty serious about it. The range
of anxiety is from very mild to the worst scenarios: “Gosh, do we need to be
worried about it getting into the blood bank. Do we need to be concerned if it’s
really causing a certain subset of prostate ca. And the latest is the
potential link reported last year of an association with CFS which would be very
exciting because that’s a disease that has struggled to find a viral cause.
Interviewer: So that might be the cause?
Goff: Could be…I talked about the behavior of the virus in culture
which in our hands is quite vigorous. It’s a very easy to grow virus in the
right cell types. Several of the talks today talked about some of the behavior
of the virus, for example it’s androgen responsive, or GRE responsive. Hormone
responsive – the receptor that it uses. Both of which bear on cell types in
which it can be found. The most recent exciting work of course is the discovery
in Chronic Fatigue Syndrome and that too is very controversial. Some people are
finding it, some not. I think that will have to be worked out in the coming
months and years. " (thanks to Parvofighter for the transcriptions).
The
first media report on XMRV from the conference appeared on
MEDPage Today
Feb 20th
- The Mikovits Cheney talk had good visuals but problematic audio with Dr.
Mikovits sounding at times like she was talking through a metal funnel but clean
transcriptions of the talk by the erstwhile Phoenix Rising Forum participants
are already going up.
Check the first out here.
- Retrovirologists Speak
- We have video from retrovirologists at the 17th Retroviruses and Opportunistics Infections in
San Francisco talking about XMRV. Dr. Goff reflected on how easy it is to grow XMRV
in the right cell types - an important finding because that allows researchers
to intimately study the virus. The fact that the virus is easy to grow in
hormone sensitive cells is important because those are the types of cells that
the virus will probably be found most readily in the body. (This apparently
suggests that immune cells will not be the main reservoir; ie the main locus
replication in the body, and it, of course, fits with the finding of the virus
in prostate tissues).
The next speaker's short presentation suggested that the research community is vigorously
going after this virus. Her work involved Emory University in Cleveland Clinic
(CC collaborated with WPI on the Science paper). It's very exciting work. The NIH has
talked about the need for an animal model of CFS for many years; this is essentially an animal they can give CFS
to and then study it in detail to try unravel what's going. They've ever done a darn thing about it - no
surprise there - but the Japanese are using
a rodent model to study this disease. Rodents are cheap and easy to work with but this group is already using a
primate (rhesus monkeys). Primates, of course, share many more characteristics with humans
than monkeys do and they're also much, much more expensive. The fact that this Emory University
researcher is already using primates suggests they're quite serious about XMRV.
They're looking at these monkeys very carefully - she just gave us a little glimpse of what they've
found - but thus far
XMRV is setting up camp in the lymphoid organs and the reproductive organs
(prostate, testes, cervix, vagina)with of these animals. The lymphoid
organs (spleen, thymus, bone marrow, etc.) create lymphocytes (among other things) - the white blood cells the
WPI was studying.
- Groom Study Issues - We've been digging deeper into the Groom UK XMRV study on the Phoenix Rising
forums with the assistance of members with technical expertise in this area. Questions regarding
the necessity of culturing the cells start to increase viral expression - before the PCR is done -
have come to the fore. My understanding is that
there’s only one reason to culture cells and that’s to up the levels of a low level virus.
The Science paper has three sections where they culture the cells; they obviously did
that for a reason – yet the Groom group ignored it and simply used unstimulated cells.
After the fact it seems inexplicable - at least to a layman - that they could have ignored such a fundamental aspect of
also wonders why after their hundreds of samples started to come up negative why they wouldn't
start culturing cells to see if that made a difference? Perhaps they thought their increased sensitivity
would enable them to find the virus regardless of whether the cells are cultured or not. Hopefully we'll
get answers to these questions at some point.
Someone on the Phoenix Rising Forums just posted a list of standard blood isolation and
amplification procedures for HIV
http://forums.aboutmecfs.org/showthread.php?3133-XMRV-CFS-UK-study-II/page52
and stated that the WPI followed most of them and the UK groups followed few of
them. If you look at the methods sections of both papers you’ll see that the
methods section for the relevant procedures are longer in the WPI paper than in
the UK papers.

- Cheney Clinic - the latest
XMRV finding has deterred the WPI not at all; they appear confident in the
strength of their findings and Dr. Mikovits will take all comers via
speakerphone with Dr. Cheney. Dr. Cheney has limited questions to Cheney Clinic
subscribers but Andrea Whittemore will take yours and pass them on at
andrea.whittemore@wpinstitute.org.
- The video from Dr. Mikovits talk at the Cheney Clinic is still not up. It
should appear here at
some point.
- A Guide to XMRV Research: the WPI Answers
Back - the inability of the second UK XMRV study – this time from a ‘friendly’
research group headed by Dr. Groom – to find any XMRV in a very large sample of
patients was rough news for sure. The ME Action Group in the UK took a rather
resigned tone in their response while Dr. Vernon highlighted a few
methodological issues but mainly concentrated on questions about that original
cohort. Neither presented much good news for CFS patients as a cohort answer to
the current problems would mean the virus is only present in a very select
subset of patients.
In their response to the latest paper the WPI defined the pitfalls they believe
researchers face in validating their work – thus basically giving them a guide
on how to find XMRV – and doing everybody a big favor.
No Replications Studies Yet Done: They
noted that no one has yet attempted to replicate, i.e. exactly duplicate, their
original study. In the best of worlds, of course, a true replication study isn’t
necessary and is, in fact, irrelevant. How one found the virus, after all, is
not particularly important; pathogens can be uncovered by several techniques and
researchers typically use different techniques to validate the presence of a
pathogen. In fact, a positive validation study using a different technique is
considerably more valuable than a replication study because it definitively
demonstrates the pathogen is there. It’s only when the validation studies are
unable to validate a finding that the issue of a true replication study becomes
important – as it now has.
Looking Back – This
replication/validation issue was prominent in Dr. DeFreitas retrovirus of almost
20 years ago. The CDC and Gow teams were well versed in retrovirology and had
used standard procedures again and again to find viruses. Given their track
record they felt little need to change their procedures. (Ultimately the CDC did
at least to some degree). But Dr. DeFreitas felt her bug was different. Given
her inability to replicate her results she may have been wrong; the question now
is whether XMRV is different as well.
Both UK studies used standard XMRV samples to ensure they could find the virus –
and their results indicated that they could – but they couldn’t find it in the
CFS patients. It may be important, though, that outside of one Japanese study
these are the first attempts to find XMRV in the blood and researchers are
treading new ground here.
We know that two US prostate cancer studies found XMRV but two German ones did
not. We know the German prostate cancer researcher is redoing his study using a
different technique. It’s clear that, irrespective of CFS, the field of XMRV
research (as small as it is), is quite muddled at this point – perhaps we
shouldn’t be so surprised about the bumps in the road encountered thus far.
The WPI took the UK study to
task somewhat for not using their reagents, blood, etc. stating that there is
only one way to look for XMRV in the blood that’s been validated and that’s
their approach and they have a point. The WPI was the first group to ever look
for XMRV in the blood and they validated their results as best they could using
the Cleveland Clinic and NCI labs. To be fair the Groom study researchers, some
of whom have long track records in CFS research, didn’t have any reason to think
their procedures wouldn’t work since apparently they do work for most viruses.
It’s possible that both they and the Imperial College researchers underestimated
the difficulty of finding this virus in the blood.
To their credit they were careful not to overstate their case simply stating in
the paper they were unable to find XMRV DNA in their samples and not making
broad conclusions about XMRV and CFS. Once the paper came out they’ve stayed out
of the spotlight – - they appear to be waiting to see what other studies turn
up.
The WPI’s Issues
Most of the issues pointed out by the WPI don’t appear by themselves to be able
to account for the differing results in the UK. String them together, though,
and you get an interesting scenario.
-
Blood Harvesting and Storage –
The idea that different blood storage and harvesting procedures could’ve altered
the results seems possible but seems unlikely (to this laymen) given that the
Groom study used three cohorts from three locations -each of which could have
used different storage techniques. We know that XMRV is robust enough for Dr.
Peterson to be able to pull XMRV out of a 20 year frozen sample but the
possibility does remain that the Groom study inadvertently used blood storage
techniques suitable for other viruses but not for XMRV. Laymen’s Conclusion – possibly a
significant factor but not likely.
-
Different Patients - The idea
that the WPI had one set of patients and everyone else had a very different
group has come up again and again. The very large size of the British study with
patients from several different groups appears to make this scenario an unlikely
one (and a decidedly unattractive one since then XMRV would apply only to very
special patient groups.) On the other hand some differences in patient selection
could start to lower the prevalence rate.Laymen’s conclusion – not ‘It’- but
a possibly a contributing factor.
-
Different Geographical Prevalence -
that XMRV is simply not found in the UK (but is found in the US and Japan) seems
have little plausibility given the fact both Dr. Mikovits and VIP Dx labs have
stated they’ve found XMRV in samples from UK patients but it’s certainly
possible that XMRV could be less prevalent there thus driving down the
prevalence a bit (more?).Laymen’s conclusion – not It either but prevalence
rates could be lower – we just don’t know.
-
Very , Very Low Levels of a Very Difficult to Detect Virus – While the other issues could reduce
an investigators ability to find the virus with the exception of the blood
storage issue it’s hard to believe they could result in being unable to find any
XMRV in a large group of patients. This low viral level issue seems to be more
significant, however.
The WPI did two things the other groups didn’t do to find the virus.
-
They Usually Grew the Virus in White Blood Cells First in Order to Increase
its Numbers. (This presumably involves hitting the white blood cells with a
substance designed to enhance viral replication). Dr. Mikovits reported earlier
that while XMRV appears to be able to readily infect immune cells it simply
doesn’t have the tools to replicate readily in them – hence its viral loads are
expected to be low. Not culturing white blood cells first could, then, reduce
prevalence rates markedly – but note not completely – as the WPI said they
usually, but not always, had to use this technique. Still the fact that the WPI
researchers cultured their cells in the Science paper was a clear sign - a red
flag one think - that viral loads were pretty low.
-
WPI researchers Had to Search Multiple Times Both in Time and Space to Find
the Virus - Not only did they
look at a sample multiple times sometimes they had to look at samples taken at
different times from the same patient in order to find the virus. The UK
studies, on the other hand, presumably looked at the same samples once or twice.
(The Retrovirology study looked at their samples twice, once using a more
sensitive technique).
- Does perhaps a bit different cohort, perhaps reduced rates of XMRV infection in
the UK, maybe some blood storage issues and a much more difficult to find than
expected virus equal zero findings in two UK studies? With true replication
studies purportedly on the horizon we’ll know in the not too distant future.
A Confident Group – The WPI
asserted, as well, that the best test of XMRV infection, given the difficulty
finding it using PCR, is an antibodies test. The Retrovirology group did use an
antibodies test but the WPI asserted that it was flawed and theirs is superior.
At the end they stated the only reliable to find XMRV in CFS is to use their
approach and basically that no-one’s going to find it until they start using
their techniques.
Feb 16th
- Dr. Vernon on the UK XRMV Study - as expected Dr. Vernon delivered a
comprehensive overview of the latest XMRV study in the Retrovirology journal.
Dr. Vernon spent some time making clear who just who did this study; it was
basically the best of UK retroviral researchers (one 'world-renowned') plus top
ME/CFS UK researchers with long histories of CFS research.
Like Dr. Shephard
she clearly felt this paper presented a significant hurdle for XMRV.
She reported that the PCR methods were identical to those used in the original paper.
When those techniques didn't find any virus they looked harder using a
different, much more sensitive PCR technique. Dr. Vernon stated it
could be 'considered better and more sensitive' than used in the original
Science paper and they stil came up nothing.
If I understood it right, Dr. Vernon also put one limb of the Science paper's argument in doubt by noting that the cross-reactivity in the antibody tests in this
study suggested that the antibody tests in the Science paper could have been due to exposure to a different virus.
Again: the Wrong Patients? - The sample came from three
cohorts. Dr. Vernon noted that because the blood from the biggest cohort came
from relatively 'new patients' (1-4 years) it's possible that XMRV
doesn't show up until later in the illness. This is not unheard of. My
understanding is that HIV often hangs out in the spleen and other immune organs
for several years before it wallops the blood cells and the low copy level of
XMRV suggests that it could have another locus in the body. Dr. Vernon discounted this idea to some
extent by noting that Dr. Kerr, a prominent ME/CFS researcher (who derives his
funding from several ME/CFS support groups), helped conceive the study and
presumably would have taken care to include more 'WPI-like' patients in the
other cohorts. Still it's a possibility.
Did a longer duration, sicker, perhaps more immune suppressed group have a more detectable
infection? Not according to Dr. Mikovits; she recently reported that patients in the study
simply needed to meet the Fukuda or Canadian Criteria for inclusion; they were
not particularly ill or disabled.
Still, Dr. Vernon took the WPI researchers to task for not releasing information
regarding the illness duration, illness severity and treatment history of that
original cohort, going so far as to suggest that their inability or
unwillingness to do so could imperil the further research into the XMRV/CFS
connection. She is clearly worried that more results like this one - which she
warned will be forthcoming unless researchers know which patients to study -
will dampen scientific interest in XMRV and CFS.
Hiding out in the UK but not the US? - She also noted that the virus could
be present in such low levels that even with their more sensitive techniques the
Retrovirology researchers couldn't find it. That begs the question, though, why
the WPI with their less sensitive methods was able to find it both before and
after the Science paper in both US and UK patients. (Dr. Mikovits noted
that VIP Dx labs sometimes searched 3 or 4 times before they found the virus -
did the WPI researchers do the same with their Science samples?)
The virus is clearly hard to find, that's for sure; of the 27 people on the Phoenix Rising Forums VIPDx Poll only about 20% tested positive
to the PCR test but 20% is still light years different from the zero percent the Retrovirology researchers reported;
given their background they clearly would have loved to find 20% positive rates.
Yes, perhaps there weren't enough long duration
and severely ill patients in the Retrovirology study and the Imperial College study but it
still seems hard to believe that the wrong patient cohort is the cause of "zero
percent" positive rates. The cause of the conflicting study results is
still very unclear.
Dr. Vernon made it clear that the DHHS studies will use different techniques, including the WPI's
original techniques, to examine people who tested positive for
XMRV via the VIP Dx lab test. This will help determine why the discrepancies are showing up.
Everyone's Doing Everything Right! - This has been a tough couple of days for XMRV
but check out this take from a researcher in ScienceNow. It suggests that
disparate results happen even in the best labs.
"discrepancies
between labs are common, says David Griffiths, a virologist at Moredun Research
Institute in Midlothian, United Kingdom, who has studied previous claims for
retroviruses as the cause of chronic diseases. He also notes that he cannot find
serious flaws with any of the published studies: "All the people involved are
doing things exactly as they should be." For the time being, then, the XMRV
results will remain frustratingly ambiguous. As Griffiths says, "There must be
an explanation for why disparate results are showing up, but it may not be an
easy thing to turn up."
- For the Full Text of Dr
Vernon's Analysis
- The ME Association is one of three ME/CFS groups that has (CFIDS Association,
MERUK) provided technical analyses of the XMRV studies. Their conclusions,
written by Dr. Charles Shepard, indicate they now believe that with this new
finding that the XMRV finding has a big hurdle to overcome. Specifically, they
point out their inability to find 'any significant fault with the very thorough
laboratory methods' in the study.
They noted that there is still no international agreement regarding how to
search for this virus and they appear to be as puzzled as the rest of us
regarding the 'starkly' conflicting results. They state the need to find the 'exact reason why there is
such a stark difference between the negative UK and the positive U.S. results.'
They are also trying to test UK patients with XMRV positive results for the VIP
Dx Labs to see how
they fare using these different techniques.
We have yet to see a US replication or validation study; it's unclear why a US
study would have different results but thus far that strange pattern persists;
every study that has looked for XMRV in the US has found it while every study
that has looked for XRMV, whether in CFS patients or prostate cancer patients,
has not. The ME Association's statement is below:
ME Association's Statement on the Second UK XMRV Study - "These new negative results, along with the negative results from Imperial
College, are in stark contrast to the very positive US results reported in
Science and they clearly place a large question mark over a possible link
between XMRV infection and ME/CFS. And while the two UK studies have been
criticised for not being pure replication studies, because they are not using
exactly the same criteria for patient selection, a significant proportion of
these UK patients in both studies must have also met the Canadian clinical
criteria. And while differing laboratory protocols were used to test for XMRV,
it is very difficult to find any significant fault with the very thorough
laboratory methods used in the new UK study.
Although some scientists will now conclude that the XMRV and ME/CFS debate is
over, no firm conclusions can be drawn until we have the results from other
studies that are being carried out, or have been completed, that are designed to
try and find evidence of XMRV in people with ME/CFS. Further results from
outside the UK should be appearing in the scientific journals in the coming
weeks and months. Whilst the two UK studies do not provide any evidence for XMRV
infection, they do not completely eliminate a role.span
class="Apple-converted-space">
One small but important add on piece of research that The MEA is continuing to
pursue is to see if some of those people in the UK who have tested positive for
XMRV using the US test can now be retested by one of the UK groups. It would
also be very interesting to see if a mutually agreed cohort of CFS blood samples
and control samples can be tested by all three UK and US research groups to see
if they produce the same XMRV results.
In the meantime, as the UK researchers point out, it is important to compare
samples and protocols between different laboratories in different parts of the
world because we do not currently have international agreement on which is the
most effective way of testing for evidence of past and present XMRV infection.
We also need to find out the exact reason/s why there is such a stark difference
between the negative UK results and the positive US results
The ME Association will continue to take a cautious, open-minded and questioning
approach to XMRV. Our advice on XMRV testing remains the same. We do not believe
there is any point, at present, in spending a large sum of money on commercial
blood testing for XMRV because the presence of this infection has not yet been
shown to be a diagnostic marker for ME/CFS or an aid to management. The accuracy
of some of commercial testing also remains uncertain.
The MEA Ramsay Research Fund - http://www.meassociation.org.uk/inde...=30&Itemid=205 - will continue to consider
applications for research funding for any aspect of XMRV research."
Dr. Vernon from the CFIDS Association is up next. She tends to give a much more technical analysis of the studies.
- Speculation on the UK XMRV Study From a Layman -
This really is a conundrum. My understanding is that the WPI is now using Dr.
Singh's XMRV specific antibody test which is showing INCREASED not
decreased rates of positivity. It appears that just as the WPI is getting more
and more internal evidence that they're right these papers are coming out
suggesting that something went wrong. The first question always appears to be
whether what the WPI found is an endogenous retrovirus - a piece of junk DNA
from an old mouse retrovirus in our genome. They sequenced 2 and a half strains
of the virus and compared what they found against our entire genome against our
entire genome and found nothing. That's one of the reasons Science took the
paper - they convinced them it was not an endogenous retrovirus.
If it isn't an endogenous retrovirus then what is it? Bear in mind that we have
yet to see a 'replication study'; no one has yet followed the WPI's study to the
letter. Different groups are doing different kinds of PCR and different kinds of
antibody tests. Theoretically they all should match up but they're not; the
twists to this story are amazing and unsettling but the WPI has the National
Cancer Institute and the Cleveland Clinic behind them; they produced 'the best'
first paper possible and it landed in the most prestigous journal in the world.
Other groups are doing more comprehensive analyses of the WPI results; Dr.
Klimas said this was going to be an up and down process - she was clearly right!
Feb 15th
- Deja Vu in the UK - XMRV CFS Study Comes Up Negative Again! UK researchers are not winning the hearts and minds of CFS patients - that's for sure.
Just a couple of uplifting weeks after Dr. Mikovits displayed so much enthusiasm
and confidence in XMRV the other shoe has dropped. An Imperial College researcher said
another negative study was coming and here it is; this UK study also failed to find
virtually ANY evidence of XMRV in a
large number of CFS patients. This study was similar and different from the
Imperial College study.
Annette Whittemore said to be cognizant of
who's doing the studies - in this case, though, there doesn't appear to be any
bias to question, no damning history
of behavioral emphasis to reflect upon; two members of the study, Dr. Kerr and Dr. Gow, are long
term ME/CFS researchers committed to a pathophysiological interpretation of this illness. (Ironically it was Dr. Gow that refuted Dr. DeFreitas
finding 25 years ago).
Indeed, the paper went to some lengths to praise the Lombardi Science paper stating the
"apparently compelling evidence against the possibility of laboratory contamination" and the
immune response against XMRV the researchers demonstrated was present. They stated that they set out
with 'the intention of confirming the Lombardi' study.
PCR Tests -
This was a large study that looked at well over 500 CFS patients and controls from two cohorts in the UK
and Scotland.
They first looked for sequences on two the three genes XMRV possesses. When they didn't find anything
the first time they looked again using a more sensitive assay.
Immune Teststs -
Unable to find evidence of XMRV by PCR they looked for signs that the patients immune systems
were reacting to it. To do this they obtained some 'neutralizing antibodies' against the 'env' protein
found in the family of mouse retroviruses. Antibodies neutralize retroviruses by attaching to them and
preventing them from getting their hooks into cells. They also raise a red flag to the immune
system to come and attack. As they examined this set of antibodies they were able to identify one that
was specific for XMRV and they used it to search for the virus.
The neutralization test is a rather indirect one; they apparently add the antibodies to the sample and
then (somehow) test the sample for 'infectivity'. Since the antibodies attach themselves to the retroviruses
the degree of infectivity should go down a certain amount and in a couple to test cases they confirmed this. When they ran the
neutralizing antibody test on the 142 ME/CFS patients none of them met the criteria for infection. Ironically, 14%
of the healthy controls from one of the healthy cohorts tested positive for infection, altho later testing suggested
it was do to a different mouse virus.
They stated that they were 'confident' that their 'PCR assay is more sensitive than the
published single round PCR method and should have possessed the necessary sensitivity to
find XMRV'.
Two Different Tests : Two Different Results - The WPI has backed away from the PCR test because
of its inability to detect XMRV at very low levels and their
associated lab VIP Dx is not longer offering it. This could not be a reason, of course, for the zero results seen in this
test - the WPI's PCR test may not be perfect but it appears to be able to find most instances of infection. We also know from Dr. Lombardi and from
patient reports that the WPI's test IS finding XMRV infection in UK patients. Why they are finding it and
two UK groups have not, is, of course, the big question. Either the patients are very different or the
tests are. Since it seems unlikely that that the patients are THAT different its pretty clear
that the WPI's test is quite different from these other groups.
Validation Not a Replication Study y -
It's interesting, by the way, that this UK group - with its ties to the WPI via
Dr. Kerr - did not appear to avail itself of the WPI's assays or or Dr. Singh's
antibody tests. Since the group didn't appear to use the WPI's methods this is a
validation study not a replication study; its was an attempt to validate the
WPI's claim that they'd found XMRV not an attempt to determine if the the WPI's
methods worked.
These are still just the first few of the XMRV studies we expect to come out
but its remarkable turnaround given the lengths the WPI, researchers from the
NCI, and the Cleveland Clinic went to in that compelling Science paper
(Dr. Coffin called it as good a first paper as they get) to demonstrate the
presence of XMRV. The fact they were able to show that this virus
was able to infect previously uninfected cells and show a virus budding out of them still seems - at least to this layman - to
be the most singular and important finding to date.
The
Scientific Director of the CFIDS Association, Dr. Vernon, will reportedly
release an analysis of the study tomorrow, giving us a much needed expert
overview of the situation.

- Dr. Bell on the Move - Our most prolific XMRV lecturer is
crossing the border to give a lecture in Toronta, Canada on March 6th. The talk is called
“Current Findings and Research into ME/CFS:
XMRV Virus and What It Means”
The talk is courtesy of the Myalgic Encephalomyelitis Association of Ontario
and the Environmental Health Clinic,
Women's College Hospital: Saturday, March 6, 2010, 1-4 p.m.

- YouTube Video of DeMeirleir
talking on ME/CFS, H2S, XMRV and more in Sweden (Nov. 2009) on YouTube.
Part I /
Part II (XMRV is in
Part II.) Dr. De Meirleir was the main driver behind the work on the immune
defect (RNase L) that lead Dr. Mikovits to search for XMRV in chronic fatigue
syndrome patients. Dr. De Meirlier, however, switched his research interest to
hydrogen sulfide about the time XMRV was found in RNase L deficient prostate
cancer patients - just missing the boat
on what may be the greatest find in ME/CFS history. It's very possible that without
Dr. De Meirleir's work the XMRV/CFS connection might never been made.
Dr. De Meirleir said he'd known of a retrovirus in chronic fatigue
syndrome for several years and referred to Dr. DeFreitas work in the early
1990's (apparently with regard to another retrovirus). He believes that some
virus mildly depresses the immune system but there are other factors. He
believes its part of the puzzle but not the complete picture. He noted that it
'seems' to be a new virus (we don't know for sure) and referred to earlier
epidemic occurrences of the disease that were caused by other pathogens.
He was grateful for the increased rate of basic research XMRV will inspire but stated
the patients will have to continue to be patient as it will take some time after that
for the clinical ramifications (ie possible treatments) of XMRV to become clear.
Dr. DeMeirleir made the point that he's getting good results with his
immunomodulatory and other treatments - stating that for patients under 30 he is
disappointed if he doesn't get 90% improvement (?!).
(Dr. Mikovits is
much more enthusiastic about quicker treatment possibilities for patients, stating in an
e-mail that she envisioned many patients being in clinical trials just six months from now.
She said she began getting calls from pharmaceutical companies the day after the Science article
hit. These companies have many retroviral products sitting on their shelves
that never made it to market with HIV. Some have gone through the steps needed to prove
they're not dangerous; all is needed are trials demonstrating effectiveness. Dr. Mikovits
has been shipping them cultures and special cell lines they can use to
test their drugs against XMRV. Sign up on
the WPI's webpage to participate in
upcoming clinical trials.
- The BEST Studies - After Dr. Mikovits talk we were able to add a couple more
studies to the XMRV Study page and we've now got
about 20 or so groups we think are trying to determine the incidence of XMRV in
ME/CFS. But which ones are the best? Which will we learn the most from. My guess
is that two sets of studies will make the most difference for us.
The Big Cahounga's - First and foremost
are the big studies from major labs that have alot of standing in the scientific
world. These would be the DHHS studies involving the NHLBI (National Heart Lung
and Blood Institute), the NCI ( National Cancer Institute) and the CDC. These
studies will do more to convince or not convince the scientific community of the
importance of studying XMRV. Given the excitement generated by XMRV its possible
that interest in the pathogen could survive some negative studies by these
groups but for the big federal money to show up one would think these studies
need to work out.
The ME/CFS Professionals -
Let's jump ahead and say those studies all work out - what then?
The big winners for us will be studies done by researchers such as Dr. Montoya,
Dr. Kerr, Dr. Klimas, of course, Dr. Mikovits and Dr. Peterson and researchers
of their ilk. Since these researchers already have so much information on
chronic fatigue syndrome and to appear to have banked their samples all they
need to is retest them and then add that data to the mix. Dr. Montoya should be
able to quickly determine EBV positive patients are at increased risk for XMRV
infection or if patients 'failing' repeat exercise tests are. Dr. Klimas will be
able to zero on the role natural killer cell functioning plays in XMRV
infection. With his now huge database of gene expression results, Dr. Kerr will
be able to see if overactive or underactive genes are associated with XMRV.
The BioBank Win -
You can quickly see just how advantageous sample repository's such as the
WPI repository or the patient BioBank the CFIDS Association of America is building
as a part of its international research network. Once a new finding is found
a BioBank can literally cut years off a research project.
- MISSING IN ACTION - The NHLBI is working away on the blood, the National Cancer
Institute has been all over XMRV for about a year, the Cleveland Clinic is
engaged, the CDC started work the day after the Science paper came out, the
Whittemore-Peterson Institute has been deluged with calls from pharmaceutical
companies and researchers wanting to get a piece of the action but Dr. Mikovits
informed us that one big player; in fact probably the MAJOR player in the field is MIA;
nothing has been heard from
the National Institute of Allergy and Infectious Diseases (NIAID).
The NIAID - there's probably more retroviral experience
in the NIAID than in any other organization in the world. The NIAID devoted so
much money to, and became so invested in AIDS (some believe over-invested), that
it came to be referred to as the 'National Institute of AIDS'. The
agency must simply be swarming with retrovirologists. It and the National
Cancer Institute are the two biggest institutes at the NIH with budgets of about
$5 billion a year.
Our Former Home - The
NIAID was also home to the CFS research program at
the NIH until around 2000. Until they kicked us out (or we we kicked them out) the
NIAID, in what now appear to be the 'glory' days of CFS research at the NIH,
funded three small but busy CFS research centers. Even though NIAID inputs to
CFS research over the past 10 years have faded badly the Institute has still
easily pumped more money over time into CFS research than any other
Institute....but now, according to Dr. Mikovits, its sitting on the fence - a
sad, sad coda for an agency that one time was quite important to us and, which
should be, if XMRV works out, very important to us in the future. Indeed, if
XMRV is found to be a major contributing factor in this disease, it's hard to
imagine the CFS program not ending up back at the NIAID at some point.

- New XMRV Test by VIPDx - VIPDx - the only lab
thus far certified by WPI to do XMRV testing - is now (almost) open for
business. As we suspected the PCR test is out and a new culture test will be
available on Feb 11th. Prices have not been posted yet but are expected to be
significantly lower. In her last lecture Dr. Mikovits stated that everyone who
tested negative in the first round of tests will be retested using the new test
using samples VIPDx put in storage. A serology (antibody test) is expected by
Spring.
- Dr.
Donnica Moore - new Whittemore-Peterson Institute Celebrity Spokesman - the
articulate Dr. Donnica is now the Whittemore-Peterson Institutes official
'Celebrity' Spokesman. Besides her medical credentials she has a son with
ME/CFS. She'll help out with awareness and fund raising.
Check out
the Press Release here.
- Meanwhile Imperial College - the group that stated XMRV is not in UK CFS
patients - announced on Feb 4th that they have developed their own commercial
XMRV test providing UK patients with an apparently surefire way of testing negative for XMRV.
Demonstrating that CDC officials do not take the cake for shooting themselves in
the foot in public, Imperial College later claimed the test was not for CFS
patients but for prostate cancer patients and then, after shutting the link
down, promised to explain on Monday - and then didn't.
- Dr. Mikovits Comes Through - Dr. Mikovits stated that she answers e-mails and
she apparently does - and in a very heartfelt fashion. This is from an email
Mark at the Phoenix Rising Forums posted.
"I
read your email just after my talk in Santa Barbara and I cried. How to answer.
I am so sorry that the tabloids made such a farce of a very real retrovirus
infection present in patients throughout the world. We have detected XMRV in
dozens of individuals with a ME diagnosis in the UK, Australia, Germany,
Scotland...XMRV is NOT a MYTH it is a very real virus that we and others have
detected. isolated and sequenced from cancer patients, CFS patients and
children!!! Please go to our website www.wpinstitute.org
or the Prohealth website to see the entire presentation which describes
scientifically all of the differences in the studies and all that we did to show
that XMRV is a NEW HUMAN RETROVIRUS of as yet unknown pathogenic potential but
significantly associated with both prostate cancer and ME/CFS
There are investigators n the UK who are taking XMRV very seriously and testing
by our validated methods and working with us to find out the truth. NOt politics
but truth. We will not stop at validation for you, Mark. We will find treatments
to give you back whatever health possible. If you send me your contact
information, I will make certain that you get tested and if XMRV positive, we
will find treatments for you.
6 months from now, I envision thousands of ME/CFS patients enrolled in clinical
trials of XMRV therapeutics.
The world-wide scientific community knows that XMRV is REAL and the best and
brightest world wide are already dedicating their talents to XMRV research!!"

- The First Retrovirus in CFS: Pt II
- I came across more information on the search for the
first retrovirus in CFS and felt compelled to flesh out the story. It was a fascinating story indeed; full of ups and
downs - periods of great excitement and great letdowns. (It certainly made a good book!). This story ends a little
differently than does Osler's Web, however. Anyway to check out the big hunt for
The First Retrovirus
in ME/CFS click here.
Feb 3rd
- Check out an interesting blog on XMRV "All this has happened before"
that examines the British response to the Imperial College study.
- The CFIDS Association of America reported the American Association of Blood
Banking distributed a
fact sheet today on XMRV. There's not alot new in this 3 page sheet; it does
refer to CFS as myalgic encephalomyelitis at one point - which has gotta be a
first for a federal agency. Somewhat humorously (or not) the AABB suggested not
to worry about XMRV, if it is infectious through the blood, to get into the
blood stream from CFS patients because most CFS patients are too disabled to
give blood. Going way out on a limb they said it would be 'prudent' to refuse
donations from people who have tested positive for XMRV but will still accept
donations from everyone else.
Feb 1st.
- The Mikovits Prohealth Lecture Slides
are now available on the Whittemore-Peterson Institute Site. The forty-one
slides present indicated how much information Dr. Mikovits imparted at the
lecture. With Dr. Mikovits sticking around and answering questions at length
this lecture turned out to be a mammoth
presentation indeed; it rang up at 25 written transcribed pages. See below for
the transcripts A report from Phoenix Rising
will be up 'shortly'.
- Who is this woman?
- The CFIDS Association just posted the first photo of Dr. Elizabeth Unger; the acting
head of the CDC's CFS Research program (as of Feb 14th). Rather aptly she's
reviewing a gene expression microrray.

Jan 30th
- Dr. Reeves Out at the CDC! In a startling announcement at 3pm yesterday the
CFIDS Association reported that Dr. Bill Reeves, the head of the CDC's CFS
Research program for the past 10 years, was out (as of Feb. 14th) and Dr.
Elizabeth Unger, a virologist and cancer specialist would be in charge as the
agency looked for a new director.
For more on this and to explore
reasons why it may have happened (including an XMRV connection?)
click here.
- A Look Back at Dr. Reeves CFS Research Program - the pro's and con's;
check it out here.
- CFIDS Association Posts Info on the Acting CFS Research Chief, Dr. Elizabeth
Unger and on the CDC organizational structure. The CAA reports that Dr.
Unger has a solid, solid background in infectious diseases and cancer, is very
well published and is currently the Team Leader of the Molecular Pathology
program in the CDC. She will not be just the acting director of the CFS Research
program she'll be acting director of the entire Chronic Viral Diseases Branch.
It appears that Dr. Reeves is not alone is his loss of a job; with a massive
re-organization going on many positions are probably simply disappearing as
different departments merge and new departments are created. It's unclear where
and under who's direction the little CFS program will end up. Jeannie Spotila of the
CFIDS Association stated it will probably be quite awhile before we know who will be running
the CFS Research team.
- Dr. Bell's hourlong January Lecture on XMRV
in Tustin, California presented by the Barborka Family is up. Dr. Bell just has
a gift of explaining difficult topics in a down to earth way. Here he presents
his very frank and objective opinion on XMRV to date; its the most exciting
thing he's seen in the disease to date and he's waiting to see how it turns out.
I loved how he elucidated how the non-XMRV PCR positive patients in the Science
study turned out to be positive (in other ways for the disease). Lots and lots
of good stuff in here.
Jan 25th
- Dr. Mikovits Speaks - Dr. Mikovits spoke and at length at Prohealth's
sponsored talk in Santa Barbara on January 22. Unfortunately the transmission
was interrupted early in the talk; it resumed later but I only caught the tail
end of it. It was clear, though, that after what appeared to be a couple of down
weeks for the WPI's discovery, that Dr. Mikovits enthusiasm
was undimmed. One thing we did learn concerned the extraordinary government
response to the discovery; Dr. Mikovits stated that the National Cancer
Institute has already spent $1 million on it. That's in 3 months....
Compare that to the $500,000 the CDC (begrudgingly) spent on the first
retroviral discovery in this illness over about a year and a half span about 17
years ago. What can we attribute to this huge increase in interest and funding
for the second major retroviral discovery in ME/CFS? It's not government interest
in this disease; the NIH appears to be spending about as much on chronic fatigue
syndrome now as it did in 1992 during the first retroviral discovery - a
shocking fact given how much we now know about the diseases prevalence and costs.
This suggests that the federal bureaucrats that funnel out the money at the CDC
and NIH is actually worse than it was then and that government
intransigence on the research level is as fixed as ever.
So how to
account for all the "CFS-Love" pouring out of the government? Basically we can
thank the Whittemore Peterson team for producing a paper that simply could not
be ignored. We can thank Dr. Mikovits for taking an interest in the subject and
putting her connections at the National Cancer Institute to work and we can
thank the Whittemore's for bankrolling what we now know is a very expensive
arena in medical research. We can also thank our lucky stars that the WPI found
this bug in the blood of 4% of healthy controls; the idea that, post-AIDS, there
was an infectious agent floating around in our blood supply was simply too
ominous to ignore - even if it came from a paper on chronic
fatigue syndrome. For once, ME/CFS patients simply got lucky.
Partial Transcription
- Dr. Mikovits talk should be up in a couple days.
Until then we have a nice transciption of the first part of her talk by 'TheFreePrisoner"
on her blog on the Phoenix Rising Forums (love that tagname!) One thing I
liked about her talk was the fact that she really started to walk us through the
technical aspects of the study and that's in evidence here.
Jan 19th
-
- Dr. Mikovits Prohealth Lecture
is tomorrow! Prohealth will be streaming
live Dr. Mikovits at 2PM PST - that's PST not EST. This is obviously the
talk not to miss. Dr. Mikovits is generally a very enthusiastic speaker; it'll
be fascinating to hear what she says after the events of the past couple weeks.
- Dr. Bell recently talked in California about XMRV. He will reportedly be
releasing his own version of the talk but until then
Chronic Fatigue Treatments has a blog on it. Its clear that right now we're getting a
lot of repackaging of some of the same information. Dr. Bell also recommended
that patients not get tested yet. He did note that the cytokine profiles of CFS
patients do support the possibility of a retroviral infection but he may have
been talking about the Science group since cytokine studies have tended to have
rather variable results in ME/CFS. Dr. Klimas 's recently released a study in
which one cytokine finding was similar to what was seen in the Science group and
another was the direct opposite. This is a heterogeneous group of people.
He
also characterized the natural killer cell problems in ME/CFS as being a 'subtle immunodeficiency". NK cell problems are one of the few immune
abnormalities that have had really consistent results across studies. Are they
important or not? Dr. Peterson appears to believe that they are; according to
this report Dr. Bell doesn't seem to believe that they are that
significant. (Can anything subtle play a significant role in ME/CFS?)
Dr. Bell also talked about low blood volume - a subject he's been concerned with
for many years. He said about 80% of CFS patients have low blood volume but there are no good treatments for
it. He believes it may be due to sympathetic nervous system problems.
- Meanwhile Dr. Klimas is Back on the New York Times - answering questions -
not on XMRV - but some very interesting questions indeed and some fuller answers
than we've had in the past. She draws some interesting parallels and notes
differences between her AIDS and ME/CFS patients. Might AIDS patients be
harboring XMRV? Yes, but its probably being knocked down by the retrovirals
they're taking. She seems to be a bit less enthusiastic about XMRV right now
stating "If
— and this is a big if — XMRV turns out to be a big player in C.F.S." but she
said little about it so I may be reading something into that.
Jan 19th
- Dr. Bateman on XMRV and CFS Research on YouTube. If, like me,
you for some reason couldn't access the webinar we can thank LuminescentFeeling
(from, where else? - the Phoenix Rising Forums) for posting on YouTube. This is
particularly gratifying since a technical glitch prevented it from being
archived. Check it out
here.
Jan 17th
- With VIP Dx Labs still undergoing updates (three days later) we're still waiting to hear just what's up
with the XMRV testing. Is PCR out? Are culture tests 'in'? We'll have to wait further.
- The First Retrovirus
- meanwhile after a fascinating read of Osler's Web I just felt compelled to
write something on Elaine DeFreitas hunt for the first retrovirus in chronic
fatigue syndrome that ended so badly for her, and really everyone else. My second read of the
book really highlighted for me what a complex thing the hunt for a
retrovirus can be. The article is too long to post here but you find it on the new
ME/CFS Front Page
Section of the Forums.
- The Polls - we've had a few more people respond to the polls. The percent
of people testing positive to PCR or culture tests is 50% (n=24). Its still
early but thus far how ill you are doesn't seem to play a role in who tests
positive. Could the low percentage of positive results for the PCR test be one
factor that is causing VIP Dx to pull back on the PCR tests (if they are?) We're
at just 26% positive. No one yet has tested positive to the Cooperative
Diagnostic PCR poll that looks at different sections of the virus.
- Don't Forget: the
CFIDS Association of America's XMRV webinar with Dr. Bateman starts at 9 AM
PST and 12 noon EST. You have to register to watch. Then in 4 days we have Dr.
Mikovits on Prohealth.
Jan 14
- WPI updates XMRV Test/Backs
Off PCR Test/Defines Relationship between WPI and VIPdx - The WPI
is continuing to refine their testing and now has an improved, less costly and
more accurate test. This makes sense with what we've heard about testing; some patients tests
are sailing right through while others are taking months to get their results. These
long waits may be occurring for those getting borderline results thus requiring VIPDx
to test them multiple times. Indeed, Dr. Lombardi statement that they considered that one positive hit in multiple tests
suggests that some samples are getting multiple tests. This
announcement suggests that that may not be as much of a problem anymore.
Or does it? Its not easy to figure out what's going.
Apparently they're using the same culture test. Does this mean the PCR is
out? It may. Unfortunately the VIPDx site is down.
- Culture In/PCR Out? - The WPI now says
that
the culture test is "the only scientifically validated methodology to
find XMRV". They state that "At this time no single PCR or whole
blood assay alone has been validated as accurately detecting XMRV, and is
therefore not an appropriate way to study or diagnose the presence of the
virus." This means that your PCR tests, while certainly not meaningless, are
not quite diagnostic yet but that the culture tests are - quite a change.
- This is interesting development to be sure; as has been discussed in this page,
XMRV is a new bug whose genetic variation from place to place is unknown; until
more is known regarding how XMRV differs from location to location its going to
be impossible to create a 'validated' test for it. The DHHS in cooperation with
several labs is reportedly doing the work.
Whittemore Peterson Institute and VIPDx Labs -
Rumors have been floating around what WPI's relationship to VIP Dx; are they partners? Does WPI own the
lab? WPI cleared up some of these questions by stating WPI gets a royalty from VIPDx for each test and
that the Whittemore's have 'an interest' in VIPDx that accrues to a trust to benefit WPI. Furthermore,
all profits from VIPDx XMRV testing will return to WPI. Their original press release
stated that the WPI started 'supporting' VIP Dx after 9/11 interrupted blood
sample shipments to Europe, presumably to the ReddLabs which featured RNase L
testing. WPI is in discussions with other laboratories
inside and outside the US regarding licensing the XMRV test.

- Dr. Mikovits Take the Gloves Off -
In an article in RJG.com, an online Reno
publication, Dr. Mikovits stated that "You can't claim to replicate a study
if you don't do a single thing that we did in our study," which was true since
Imperial College's attempt was a validation study and not a replication study. Dr. Mikovits
went a considerable step further, however, when she claimed that they actually tried NOT
to find XMRV by skewing their experimental design. Just getting started she slammed
them for paying to get the study published and suggesting that the insurance
companies were behind the study.
Strong words indeed and not often heard from researchers. Unfortunately
RJG.com didn't print the details of how Dr. Mikovits felt the study was skewed
(patient cohort?, water sample?). The WPI took them to task for not
replicating the orginal study but its
clear that they feel the group didn't do the validation part correctly either;
ie if XMRV was there they don't believe they would have found it.
It's unfortunate indeed that the first 'replication' attempt was from such a
suspect source. While Dr. Mikovits pointed out how anxious the Imperial College
finding had made patients, aside from that, this brouhaha will notmake any difference as the studies
from different groups and with different patients come flooding in.
Finding out what's up with this newly discovered bug will take time and study.
Annette Whittemore calmed things down a bit when she stated that
We think XMRV is, at the very least, a biomarker for a subset of patients with
Chronic Fatigue Syndrome." which is a good safe statement to make. 'XMRV',
whether or not it causes ME/CFS, would make a great biomarker because it appears
to be rarely found elsewhere but is found in at least a significant percentage
of CFS patients. Researchers have been looking for a biomarker like that for over 25 years
and have turned up nothing.
- Imperial College Responds
- Meanwhile Dr. Cleare responded to questions about the patient
cohort in the Imperial College Study. He asserted that the patients in the study were much like
patients everywhere; they all met the standard (Fukuda) definition, most experienced physical and
mental fatigue, most experience post-exertional malaise. They exclude most psychiatric
disorders including somatisaton -which they say is rare anyway. Nor did they try to 'shape'
or 'select' the patients appearing in the Imperial College study. Nor is this group more
'psychiatric' than other groups and, in fact, they resent the implication that they are.
As a laymen, it seems highly, highly unlikely to me that a different cohort could account for
the results of the Imperial College study.

presentation here. and
Prohealths Presentation here.
- Gordon Medical Associates is a medical group that's been working with
the Whittemore Peterson Institute on XMRV. They just sent us a little update
which again suggests that the testing side has hit a few bumps. Dr. Lombardi
recently stated that the viral copies of the virus were very low and that the
testing process was quite slow. Gordon Associates first called for a bit more patience and then stated
that XMRV is
being a bit 'difficult'.
"First,
those GMA patients who were tested in either one of two studies need to stay
patient a little longer. We have provided over 130 samples to Dr. Judy Mikovits
for extended testing for XMRV. Dr. Mikovits tells us most of those samples have
been tested, and that we will receive the results as soon as they are finished
analyzing the data. Those who provided samples to Panorama labs will also need
to wait. XMRV is proving to be a difficult virus to find in testing, and
both labs are working to do their best to provide accurate information."
Jan 11th
- Dr. Bell Speaking in Santa Ana, Ca on XMRV January 15th
- Cooperative Diagnostics Results Top VIPDx Results - Neither poll is anything to
cheer about regarding participation but it's remarkable that we now have more results from the
CD PCR poll (13) than the VIP Dx PCR poll (11). (The combines VIP DX PCR/Culture
Poll is still tops with 16 results). Given that
the WPI and Dr. Coffin both thrashed the Cooperative test when it first came it
this can only suggest that VIP Dx Labs is moving very, very slowly.
Meanwhile no one has tested positive for Cooperatives two gene sequence PCR
test and only 18% are testing positive for VIP Dx's one gene sequence PCR test.
(66% of patients in the Science paper tested positive.) Fifty percent of
patients are testing positive, however, for either a PCR or the culture test
which is a bit higher than the 36% rate reported by Glean in his article.
- My Cooperative Diagnostics Test -
I received my test result back from Cooperative Diagnostics. I was, like
everyone else who has taken the poll thus far, tested negative. I was able to
get the test done because I was part of an XMRV study CD is doing.
Given the results of the Imperial College tests the results are illuminating
because both groups appear to be using a similar strategy; ignoring the
sequences the WPI tested for and instead focusing on sequences they know (or
believe they know) are there. This is certainly a legitimate way to test for
'XMRV' as we know it. Whether its a good test for what the WPI found is another
question.
This is what they said.
The two strains of XMRV found by Lombardi et al in chronic fatigue syndrome that
were sequenced had roughly 6 bases that were different from prostate cancer
XMRV. We used these strains in addition to prostate cancer strains and several
strains of murine leukemia viruses (MLV) in the design of our test. In contrast
to published tests for XMRV that have been designed in highly variable DNA
regions in the MLV family ... we chose to design our initial test to use the pol
gene so it could detect all MLV species, including XMRV. This means we tested a
DNA sequence that has not changed in hundreds or even thousands of years on an
evolutionary scale in the MLV family. This test would be more apt to detect XMRV
than any other test used. Therefore, we would likely have more positives than
previously reported in PCR tets for CFS when XMRV is actually present.
We also used a superior test sensitivity, enabling the detection of 10 to 25
times few viruses in a blood sample than previously reported tests for XMRV.
This was proven when we were able to detect XMRV in 1 infected 22Rv1 cell from a
commercially available prostate cancer cell line in a background of 2.5 ug of
extracted DNA from blood. We also designed a second test with the same
performance characteristics of the first. This allowed us to also evaluate the
env genes, creating an extra confirmation step in our testing.
A Laymen's Assessment of the XMRV Situation (Laymen in Charge - Be Very Wary)
-
REPLICATION VS VALIDATION STUDIES -
the Imperial College and CD tests are validation 'studies' not replication
studies and there's a big difference between them. Replication studies follow
the first studies techniques to the letter.They're using the same processes to
find the same genetic sequences that the original study found.
Validation studies, on the other hand, simply try to validate the first studies assertion - in this
case the WPI's assertion that they found XMRV. They're not trying to replicate
the original techniques; in fact, it's better if they don't. Virus hunters can
use any number of techniques to find a virus; if a virus is there any of these
techniques should be able to find it. Thus, they're often using different kinds
of PCR tests and are often looking for different genetic sequences than in the
original study. When Imperial College or CD attempts to detect the virus using a
different means than the WPI does, its trying to validate their assertion that
they've found XMRV - not find the same genetic sequences WPI did.
The WPI's Variable Genetic Sequences -
It's intriguing that CD states that the tests thus far developed for XMRV
focused on 'highly variable' regions of the DNA (we heard this from another
researcher). The WPI tested 'gag' sequences which, as I remember, are from the
coat of the virus. Since this part of the virus is constantly interacting with
the environment it's not surprising that it might be variable.
Cooperative Diagnostics states, though, that ALL XMRV tests, not just the WPI
test, have focused on variable regions of the genome. The upside to that
approach appears to be that these tests can differentiate between different
types of murine retroviruses; ie they can pick out XMRV from other murine
retroviruses. The downside is that because they are variable they could
conceivably differ from strain to strain and patient to patient - thus some
patients could test negative when they're actually positive.
Cooperative Diagnostics Conservative Search for XMRV -
Cooperative Diagnostics is taking a very conservative approach by focusing on
highly stable regions which are shared with other retroviruses. These were gene
sequences in the pol gene that are believed to have been stable for 'hundreds or
even thousands' of years. Since several viruses share these regions they
expected higher levels of false positives ; ie if anyone carried those viruses
they would show as testing positive for 'XMRV'.
Highly Sensitive - They also
developed the most highly sensitive test yet. They demonstrated the test was
able to identify even very low levels of the XMRV virus found in standard
preparations of prostate cancer cells.
Two Genetic Sequences - They also looked at at the
env gene sequence found in the XMRV. This is the sequence that the Cleveland
Clinic - in small number of samples - demonstrated was in the WPI samples - and
helped convince them the WPI had found XMRV. Because Cooperative Diagnostics is
looking two stable sequences they appear to be providing the most comprehensive
test for XMRV commercially available.
At least in my sample and the 12 other people who voted in the poll none of us
tested positive for these sequences; ie we did not have XMRV.
NOT XMRV? - eaving aside different patient cohorts, geographical locations, and other
confounding factors the Imperial College and CD findings thus far refute the
WPI's claims that they found XMRV. Instead they suggest either that the WPI
found a different type of XMRV or some gene sequences that are similar to those
found in XMRV but not the actual bug itself.
The Weak Link? - it could be
that XMRV is more variable than researchers know; that they're looking for gene
sequences that are slightly different than the standard XMRV sequence. That
standard XMRV sample, after all, must have come from prostate cancer studies
from a small probably localized set of patients and may not reflect what XMRV looks like
in the rest of the population. The problem with this argument is that
Cooperative Diagnostics tried to account for this by looking for a genetic
sequence that they don't believe changes between several viruses alone within a virus -
and didn't find it.
Contamination? - Its also
possible that the WPI is picking up an endogenous retrovirus that has some
similar genetic sequences to XMRV. This is the 'contamination' theory which no
one really seems to take seriously. For one thing the WPI fully sequenced two
samples of XMRV and parts of third and they had very close genetic similarity to
XMRV
The BATTLE
-
Evidence For the WPI's Assertion: they
identified a 'gag' sequence that appeared to come from XMRV. The Cleveland
clinic confirmed that seven of 11 patients also had an 'env' sequence.
Importantly, the WPI sequenced 2 1/2 strains of the bug from their patients and
it turned out to be XMRV. The weak point here was that the 'gag' sequence is
variable in XMRV but they have that full sequencing of strains to back them up - strong
evidence in their favor. Plus while it's not evidence for XMRV the WPI did find
something that was able, to jump from an infected cell to an uninfected cell in
a culture test; this doesn't appear to be a fragment of something - it appears
to be 'something'.
Evidence Against the WPI's Assertion: One study and the poll results from
another labs test that looked for very stable genetic sequences in XMRV have not
found them; ie no XMRV. Since they haven't
found any XMRV it's clear that patient cohorts are not the complete answer.
A Conundrum - There doesn't
appear to be any good answer - we're at a conundrum. Short of someone having
made a technical error its hard for this layman to understand these conflicting
results. Perhaps the best way to leave it is that XMRV is a newly discovered
retrovirus and much remains to be learned about it.

- VIPDx - An enterprising member of the Phoenix Rising Forums asked VIPDx some
questions about their tests and they answered right back. When asked about that
rather low 36% positive rate VIPDx replied
When Whittemore Peterson did their research it was on a small group of patients
who have a “confirmed diagnosis” of CFS.
VIP Dx is testing hundreds of patients whose medical history is unknown and a diagnosis
of CFS may or may not be confirmed.
Although we strive to offer the most sensitive test available XMRV is typically
present at a very low-copy number and may be below the limit of detection from time
to time.
Retroviruses (like XMRV) are integrated into cellular DNA and are considered life-long
infections; it is possible that the immune system may decrease the virus to a level
below the limit of detection from time to time (non-symptomatic). Presently, the
life cycle of the virus is unknown; if you receive a positive result at any point,
we do not recommend re-testing.
XMRV testing at VIP Dx uses the same methods as published in the Lombardi, et al,
October 2009 issue of Science. This test included PCR testing on lymphocytes as
well as virus culture. This method requires 20mL of whole blood and although it
is much more time consuming and labor intensive than other methods, we find that
it dramatically reduces the rate of false negative results. It is also why the cost
of this test is greater than that of tour standard PCR tests.&
Thus there are potentially two reasons for the lower than expected (but still significant)
rate of positive results (a) different patients (b) the virus could actually be
there but in numbers so low that its difficult to find at any one time. One
member of the forums sent his blood in in Nov and still has not gotten a result.
On the other hand a few people who have sent their tests in got their results back
fairly quickly. It sounds like there are some borderline results that VIP Dx is
being careful with; which is good to hear but also suggests they haven't nailed
the test down completely yet. (?)

- Biff! Bam! Boom!
- the Economist weighs in with characteristically fun to read
article that actually brings up some potential problems with the study.
- Dr. Donnica
is back! Check out our best spokeswoman for this disease on a video she did
for the Doctor's Channel where Doctor's talk to Doctor's. This is short
general introduction to CFS (no XMRV) but it's nice to see. She gets MCS in
there.
- Dr. Enlander
Talks! - Dr. Enlander also did a very short video for the Dr's channel.
Its great to see ME/CFS specialists talking to Doctors about this disease (instead
of CDC personnel). Dr. Enlander gets myalgic encephalomyelitis in his short talk.
No XMRV here either but you've got to think the interest in XMRV is sparking
more interest in this disease in general. Dr. Enlander will have a talk on XMRV
coming out.
Jan 7th
- Imperial Study Fallout: Day Three - there's nothing like a failed replication
replication attempt to get the information flowing.
Sam Kean of ScienceNow reported that after questioning why the Imperial
Lab didn't look at the same genetic sequence, Dr. Lombardi stated that after 300
tests (only 300 in a month plus?)VIPDx is getting a 36% positive rate - about half
found in this study and far fewer than the 95% reported after the study. Meanwhile
VIPDx Labs is getting some heat for offering a $650 test that (a) has not been standardized
and (b)for a bug whose effects are clearly unknown.
Dr. Coffin, one of the top retrovirologists in the nation, suggested that both groups
could be correct and this seems to make the most sense at this point. Some research
groups are choosing not to use the genetic sequences in the WPI test because, at
least according to one source, they come from a more variable region of the genome.
Instead they're looking for genetic sequences that they know are stable in the
virus. XMRV is, however, a new virus which has not been well studied. Although XMRV's
genetic variation in the US appears, at least at this point, to be quite low its
possible that the genetic sequences outside the US are different. If this is so
then a probe using those sequences wouldn't pick up any evidence of the virus.
Jan 6th
And if you see some negative papers coming out, don’t be discouraged. It’s
going to happen. There are going to be some negative papers. People really jump
to do this. And the method is not that easy and getting the right bits and pieces
you need together (is not easy)" Dr. Nancy Klimas
- Whittemore-Peterson-Institute
Responds - The WPI iweighed in the next day and in very blunt language took
the Imperial College study to task calling it 'meaningless'. Besides
the different patient cohorts and different blood sampling procedures they
cited
- the use of a water control rather than a blood control
- different primer sequences and amplification protocol which was not validated by
a clinical control
- fewer rigorous tests of accuracy
If I understand them correctly they're also assert that the group should have
used an positive sample from a patient rather than a standard XMRV sample as a control.
Plus they did more tests involving three different labs to ensure accuracy than
the Imperial College group. Plus they had questions regarding the different
protocols.
Its getting pretty muddy here. One thing we're going to see are studies replicating
their results against standardized XMRV samples (eg Imperial College) or against
positive samples from the WPI. Theoretically, if both samples contain XMRV they
should produce similar results but if the 'XMRV' in them is slightly different
it could create problems.
There are differences of opinion regarding how exact a lab needs to be in replicating
another labs results. There are several different PCR techniques and variations
within each kind of technique. Some researchers assert that any valid technique
should yield positive results. Others believe slight differences can make big differences.
At this step of the game - with such a new finding - it seems pretty clear that
the first priority is exactly duplicating the original study's findings.
- The Brits Smack XMRV or Do They? - Attempting to stop the bleeding in the media
which appears not to be paying attention to any of the possible problems in the
UK study the
CFIDS Association of America produced a press release that stated in no
uncertain terms their concerns about "many elements" of the study including
the rush to publication (three days between submission and acceptance), the different
processes used in the two studies and the differing patient groups.
Dr. Suzanne Vernon, the CFID's Associations Scientific Director produced the critique
of the study and the CAA touted her credentials in Press Release; a directorate
in Virology and 17 years years of public health research on infectious diseases.
Dr. Vernon closed the press release alluding to a need for a 'standardized test'
before millions of dollars of funding are potentially wasted. Developing a standardized
test requires having multiple labs test and retest different procedures until they
all agree they have found the correct test. Only then will it be possible to determine
the true prevalence of XMRV.
Gird Your Loins ME/CFS Patients - in the meantime Dr. McClure's comments
suggest we may be about see a stream of similar findings. A participant in the Phoenix
Rising forums reports a CDC report will be out next week. Now is the time to member
both Dr. Klimas and Dr. Vernon's admonitions to sit tight and not take any one (or
two) results too seriously at this point.
Meanwhile the WPI remains silent but are reportedly working on their response.
- The Differences in This Study - How did this study differ from the Science
study?
Its Location - the disconnect between researchers ability to find XMRV in
the US and Europe is growing; both attempts to replicate XMRV findings outside of
the US have failed; both a large German study prostate cancer and this large UK
study found zero evidence of XMRV. Is this due to differences in XMRV prevalence
or to differing laboratory procedures? Patients report that Dr. Mikovits stated
there may be significant geographical differences in prevalence in the US;- some
regions reportedly had much rates of infected CFS patients than others in their
testing. XMRV has, reportedly, been found in Europe, however, and its hard to imagine
that the geographic differences could be that distinct. Laymen's assessment
- if its a problem its not THE problem.
Different Gene Sequences - The Imperial College Group did not search for
the same sequences as did the WPI. They may be following a somewhat similar technique
to the Cooperative Diagnostics Lab. Cooperative Diagnostics reported that the WPI
looked at genetic sequences that contain high variability. Because of this they
searched for genetic sequences that have been stable for long periods of time. It's
possible the Imperial College group used the same rationale. Laymen's assessment
- possibly a key issue
Blinded Study - the Imperial College Study was 'blinded', albeit in a strange
way. Although the PCR technician didn't know which samples he/she was assessing
all the samples came from CFS patients or 'water controls'. Although the
WPI study contained healthy controls it was, apparently, not blinded. Laymen's
assessment - not a huge issue; differing percentages of positive patients could
be attributed to operator error - but not to such huge differences.
Different Procedures - Dr. Vernon has noted that several techniques were
different in the two studies. Some researchers will argue that techniques don't
have to be replicated exactly for a robust finding to show up. Others argue they
do need to be replicated exactly. Inexact replication of the first retroviral finding
was a major controversy of the first retroviral finding in ME/CFS and experts differed
on whether it mattered or not. Laymen's assessment - potentially a major issue.
Different Patient Groups - the Imperial College group used quite ill patients
who met the CDC criteria judged (by the investigators)to be 'typical' of chronic
fatigue syndrome patients in Australia and the US. Its possible that the WPI group
(immunologically challenged with metabolic dysfunction) were a different subset.
However, in a large group of CFS patients (168), surely a good portion would fit
the WPI profile, and no patients at all tested positive. Laymen's assessment - if
its an its not THE issue.
Laymen's Overall Assessment - This is a methodological problem rooted in
the complexities of PCR analysis. (Any PCR experts outs there?)
Jan 5th
- First XMRV Replication Study
Published - and its a doozy. Originating from the Imperial College and with
patients supplied by Simon Wessely, the study found zero (that's zero!) evidence
of XMRV in 186 CFS patients. Here's a link to an article by the BBC
and a link to
the original paper
The basics of the study were that they looked at a lot of patients (186) who were
quite ill (only 19% working), had high rates of disability, about 50% of which
had infectious onset. They all met the standard CFS Criteria (1994 Fukuda) and they
did not have a major psychiatric condition. (I'm unclear if depression is excluded
or not). The researchers did not test healthy controls. They had a positive
sample of XMRV to ensure that they could find the virus.
Remarkably, they didn't find the virus in any of the samples - a similar
finding to an earlier German study that failed to find XMRV in any prostate cancer
samples. These studies underline how complex situation these efforts are. Earlier
the CFIDS Association noted that the German study did not adequately replicate the
original XMRV prostate cancer study. Now Dr. Vernon of the CFIDS Association asserts
the same is true with this Imperial College study.
In a CFIDS Link report
Dr. Vernon stated that this study 'should not be considered a valid attempt to
replicate the findings" of the Science Study. Basically she listed a
series of methodological questions that could have interferred with the Imperial
College Researchers ability to find the virus. Most of these will fly right over
most of our heads but they include:
- collecting the virus in different kinds of collection tubes
- the DNA from the patients was extracted and purified in a different manner
- they used different amounts of DNA to amplify their assays
- they looked at different parts of the genome
- tthey ran the PCR under different conditions
Based on Dr. Vernon's experience working with PCR any of these could have
affected the results. She didn't say that they did but that they could have.
She then pointed to a larger much more rigorous study that the Department of Health
and Human Services is engaged in. (Both Dr. Vernon and Dr. Mikovits are part of
a team overseeing that study). Since that study will involve multiple laboratories
coming up with a standardized test first that study will take longer to finish.
She did say that the CFIDS Association is urging that the DHHS study is completed
as expeditiously as possible. She, also, like Dr. Klimas urged patients to be prepared
for conflicting results'
"The
U.S. Department of Health and Human Services Blood XMRV Scientific Research Working
Group is conducting a rigorous
study to detect XMRV. Multiple laboratories will standardize methods to optimize
sensitive detection of XMRV proviral DNA and viral RNA and then, once methods are
standardized, these same laboratories will test coded panels of blood samples obtained
from healthy blood donors and CFS patients. We look forward to the results
of this study and urge that it be completed expeditiously, especially in light of
this report from the U.K. In the meantime, be prepared to read about more studies
with conflicting findings. Rather than simply accept or dismiss new information,
we will help make sense of why discrepant results occur."
It sounds like this study will most likely be the gold standard for XMRV study.
It may, is more than any other study, be the one that validates does not validate
the Whittemore Peterson Institute's findings.
Jan 4th
- Dr.
Mikovits will be giving a 2 hour presentation on XMRV in Santa Barbara on
Jan 22nd. Tickets are still available. Prohealth will also be streaming live the
presentation but definitely get there if you can. My experience with Dr. Mikovits
is that she's very approachable and she's happy to answer questions before
or after a presentation.
Dec 30th
- A short article
on XMRV had Annette Whittemore stating, rather positively, that “We’re very hopeful
that within the year, we will begin to see clinical drug trials for XMRV-related
diseases such as Chronic Fatigue Syndrome, fibromyalgia and many other unknown diseases"
Nothing the WPI has seen in their labs over the last couple of months since the
Science article came out has compelled them to pull back on their expectations
at all. Particularly intriguing is Annette's statements about 'many other
unknown' diseases. Does she mean poorly understood diseases like MCS or IBS?
Or is she referring to neurological disorders that simply haven't been described
adequately yet? Diagnosing brain disorders can be very sketchy; patients often don't
fit into the standard 'autism' or 'multiple sclerosis' profile -
there's alot of drift in there. Is Annette talking about a new group of XAND
(XMRV Associated Neurological Disorders?).
The WPI is clearly engaged with many groups spread across the US and Europe with
Annette stating “We are continuing to work with the National Cancer Institute and
many other individual researchers,” Whittemore said. “We also are doing confirmation
studies of additional Chronic Fatigue Syndrome patients with other countries, including
Sweden, Norway and the United Kingdom, as well as many scientists across the United
States.” - Cooperative
Diagnostics Lab and VIPDx Polls Show Divergence - We still have an almost inexplicably
low number of people participating in the XMRV Testing Polls but even so we have
a divergence in the results for the PCR tests. Thus far 30% of 10 people have tested
positive for the PCF test from the VIPDx lab but nobody yet has tested positive
(8 results) to the Cooperative Diagnostics poll. As Nancy Klimas pointed out we
should expect divergent test results until a standard test has been developed.

XMRV Media Thread on Phoenix
Rising - We've had quite a lull in XMRV news so perhaps its a good time to check
out of my favorite features in the XMRV section of the Phoenix Rising Forums. Summer
created a media section that contains short excerpts and/or links to media articles
on XMRV. Thus far over 80 posts have been made.
In this one
From Women's Day
Dr. Mikovits states people might want to put off being
tested for now since there are no good treatments for some XMRV yet. She also says
that treatment trials at the Whittemore Peterson Institute could start as early
next year.
There's also this YouTube video
from Imogen Heap on XMRV . There's lots of stuff on the Media Page.
If you want to look back at what's happened or if you want to see you might've

Dec 24th
- Dr. Bell's Latest On XMRV
- One section from Dr. Bell's December Lyndonville Newsletter is worth quoting
in full because it is so timely. XMRV studies will at some point start pouring out.
Both Dr. Klimas and Dr. Bell have stated that the important thing, particularly
in the early stages, is not to over-react to negative or even positive reports.
As Dr. Bell explains the process is more complex than we know and that it will take
some time before we know what's really what.
"...Not surprisingly, the first stage of the attempt to replicate these
results has resulted in various international groups almost entering a race to see
who could replicate or refute the WPI results first. And this has meant they have
gone for an easy and immediate source of patient material - stored blood samples.
I am not aware of any stored blood samples here in the UK that are from patients
who meet Fukuda plus Canadian criteria and I doubt if there are any."
This brings up really important issues in interpreting the results of studies that
will come out over the next six months. In my practice over the years, I have seen
the whole range of patients from kind-of tired to bedridden orthostatic intolerance.
Despite what the different criteria attempt to prevent, much of the diagnosis is
based upon using the "force". There are some clinicians who diagnose CFS
and I have absolutely no idea of what their patients are like. Through years of
observation, I do have a concept of what Dan Peterson's patients are like.
So is XMRV in really severe ME? CFS? Orthostatic intolerance? CFS plus POTS? Mild
fibromalgia? Atypical MS? CFS with or without depression? Chronic Lyme disease?
Multiple chemical sensitivities? And what about stored samples? Samples taken in
EDTA or heparin? And so on.
So what does this mean? It means that if someone can't find XMRV in a study,
it is either because it is not in the patients they tested, or their lab could not
detect it even if it was there. Or the strain might be different, or they used the
wrong tubes, or the diagnosis was wrong. And on and on. Again using the "force",
I would not be surprised if some of the quickest replication studies fail to confirm
XMRV. But as long as people do not jump to conclusions too quickly, science will
win out. Truth will win out. That’s all I am looking for."
Interestingly, Dr. Bell felt that the Dubbo studies would be a fantastic test for
XMRV. Since these studies examined people as they came down with CFS (or not) following
an infection if XMRV was found in those who came down with CFS but not in those
who did not following the infection it make a strong case that an XMRV infection
somehow primes people for a descent into CFS once they get another infection.
As you may remember, a small percentage of persons developed ME/CFS after Epstein-Barr
virus, Ross River virus or Q fever. They must have saved blood from those who came
down with ME/CFS and those who did not. Test the blood for XMRV. If it is in the
ones who came down with ME/CFS, but not present in the blood of those people who
had regular mononucleosis and quickly recovered, we would have the answer. Ah…if
only it were that simple…
A patient has reported that Dr. Lloyd's XMRV study of the Dubbo patients will be
released in January. (See below)
- XMRV Study Page - The
studies are adding up. We're up to fifteen studies/groups focusing on XMRV and we
may have identified our first release; Dr. Lloyd of the Dubbo studies in Australia
is reportedly releasing his results in January, 2010

Forms - Participants in the Phoenix Rising Forums just started the XMRV Global
Action Group to 'accelerate global access to diagnostics, clinical trials, treatment
and prevention for diseases associated with the retrovirus XMRV"
Check out their Facebook site.
- DiagnoseSupport is focusing on getting
the word out internationallly about XMRV Section and are providing translations,
etc. They've joined with the XMRV Global Action group.

- The Autism-XMRV Connection - Dr. Insell, called the 'nations top research
coordinator', expressed
real interest in the XMRV autism connection. Not long after the publication
of the Science paper Dr Mikovits reported that 40% of a small group of autism patients
tested were positive for XMRV. Dr. Insell is taking a real interest in XMRV,
stating
"We are hot on that, and I wish I could tell you more," Insel said. "All
I can tell you is that we have an intramural program here which is kind of our home
team, which has seen about 400 kids with autism over the last couple of years. And
they have been looking at regression; they've been looking at recovery."
He said the researchers "jumped on the XMRV thing even before it was published."
Dr. Insel said that he had heard that researchers at the University of Nevada had
identified XMRV in about 40% of ASD children studied. "I have been trying to
track that," he said. "There is a paper that has been submitted, but
I haven't been able to get it, and I don't know what the data look like.
But I think this is really interesting."
Why? Because, he said,
"If we could just find a small group, and the opportunity
to begin an antiretroviral treatment regime, that could be terrific. That would
be the kind of thing we're really looking for in this field, is finding the
subgroups that might have specific therapies that would make a difference."
- Whittemore Peterson Institute and the Friends of the Whittemore Peterson Institute
- there are two Facebook sites on the WPI. The
Whittemore-Peterson Institute Facebook
site is the official WPI Facebook
site. You can find the WPI's latest releases on XMRV and other subjects relating
to ME/CFS there. The
Friends of the WPI has been a site for people interested in XMRV and
the WPI to gather and discuss the Institute and its findings. The WPI will eventually
eventually close that site and is asking everyone to move to the WPI Facebook site.
Annette Whittemnore penned a Letter from the Whittemore Peterson Institute
on December 19 outlining what Institute has been up to and the impact its
made.

- The XMRV Polls on
Phoenix Rising - The results are slowly trickling in with just 12 people thus
far taking both the PCR and the Culture tests. Of these 50% tested negative to both
tests and only 25% tested positive for an active (PCR) infection. On the other
hand regard to the separate Culture test - which test to see if XMRV is present
in the cells about two thirds of the people have tested positive.
That "Latent' Virus- My understanding is that researchers
refer to viruses that are not traveling in the bloodstream and infecting other cells
as 'latent' but that they are discovering that 'latent' is
a decidedly poor choice of words as these viruses can be quite active in the cells
they're found in. Since XMRV appears to be found them immune cells it could
be disrupting their function - latent does not necessarily mean not significant.
It does mean the virus does not appear to be actively spreading in the body.
Having a negative test result may or may not be positive event depending
on how you view the situation. Check out how
a member of the Phoenix Rising Forums
is dealing with her surprise at her
negative result.
Both Dr. Klimas and Dr. Bateman and, in fact, the Cooperative Diagnostics Lab -
suggest patients not get tested until we have a standardized, independently validated
test. This doesn't mean the VPI Dx test is not good - it was clearly good enough
to get into one the most prestigious journals in the world - but that it's probably
not perfected; that is while most of the people taking it will get an accurate result
there will be some people, probably only a few, who may not. That's my understanding.
A standardized test paid for by insurance may be ready in six months.
- More From Dr. Klimas - Dr.Klimas cautioned everybody not to get too
excited if some negative studies pop up - she expected to see studies with highly
positive and highly negative results show up and everything in between. She
noted that she's been contacted by several researchers who want access to her
samples but she's been very careful. Because researchers use a variety of different
methods to look for viruses - and methods to make all the difference - she's
focusing on what methods they're using.
It sounds like we should be ready for a rather turbulent period! Enough attention
has been focused on this virus, though, that Dr. Klimas seems fairly positive that
the research community will get to the bottom of what's going on; ie. we won't
be left with lingering questions as we were after the DeFreitas retroviral finding
in the early 1990's.
Dec 16th
- Dr. Bateman's Lecture on XMRV
- this is almost an embarrasment of riches. A video of Dr. Bateman's recent 1 1/2
hour lecture on XMRV has just been posted online. Dr. Bateman is one of most active
physicians serving on the CFSAC and IACFS/ME. She runs the OFFER group in Salt Lake
City and is well acquainted with Dr. Peterson's work. She is another professional
who came to ME/CFS the hard way - her sister died of CFS. (While you're there
check out OFFER's large selection of video presentations). Like Dr. Klimas Dr.
Bateman is an ace at presenting scientific information in a clear, understandable
manner. She was more cautionary than Dr. Klimas regarding XMRV.
Inheriting XMRV? - Both she and Dr. Klimas talk about the possibility that
you could've inherited this virus! Its clear that mice pass this virus down in their
genome from generation to generation. Do humans as well? No one knows but its definitely
a possibility. (You can see why the retroviral community is so interested in this
virus - its an interesting virus! Like HIV its a retrovirus but its like the UN-HIV
otherwise; its possibly inherited, its not replicating much, and it doesn't mutate
much - its like the other side of the retroviral community
just showed up in humans and the researchers would love to get their hands on it.
Dr. Bateman noted that its gotten very little study thus far - thats clearly changed.)
That Special Cohort? - Dr. Bateman emphasized how ill the patients in the
Science study were and that its unclear how the findings will translate to more
typical patients. She noted that the tests to identify haveXMRV are "new, imperfect,
(and) not standardized" and rattled off a stream of difficulties associated with
PCR, antibody and culture tests; testing is very new and its evolving.
Treatment - Just as Dr. Klimas does Dr. Bateman emphasized how toxic many
HIV drugs are; she noted they were developed to save the lives of people who were
dying and that the medical community was willing to tradeoff a high degree of toxicity
for saving lives. They can cause a pain disorder (peripheral neuropathy), 'drop
your blood counts', give you diabetes, etc. The pharmaceutical community is
definitely interested; they are already moving into animal testing and Dr. Bateman
has already been approached about being part of clinical trial network.
The mouse - human connection - We know XMRV came from mice - but when did
it jump to humans? Several researchers have suggested that it was fairly recent
but Dr. Bateman noted that XMRV has probably been in mice for millions of years!
Like Dr. Klimas Dr. Bateman noted that sexual transmission does not appear likely
- given the epidemiology of CFS (few husband/wife pairs).
Testing - Dr. Bateman mirrored Dr. Klimas' suggestion regarding testing -
she advised patients not to get to tested yet. Enough interest has been generated
in the research community that it won't be long for a test that's been independently
validated and standardized to appear. You could falsely test positive or falsely
test positive. She also noted that there's no treatment for XMRV yet. She also believes
the study results will run the gamut: from almost no patients having the virus to
most patients having the virus depending on what types of patients are in the study
to what kinds of tests they used.
The Autism Connection - the WPI didn't just look at any autism patients,
they looked at flu-like onset autism- these were the patients they found XMRV in.
Dr. Bateman is VERY excited about the XMRV finding- what is looking forward to right
now is more clarity about it - which will simply take some time.
Dec 15th
- The WPI has a new partner (and we have a new study) The distinguished Cornell
University in upstate New York has just posted a job offering for a postdoc for
study on XMRV in ME/CFS. Both the WPI and the Columbia University Center for Infection
and Immunity are partners. (thanks to Parvofighter for the tip)
- The XMRV studies keep adding up and now Phoenix Rising has
a page specifically devoted to them.
- Dr. Klimas' lecture - meanwhile more interesting
stuff from Dr. Klimas' XMRV lecture. She does not
recommend a test right now; for one the tests are still being tweaked - you could
get a false positive or negative and for two - there's really nothing you can
do about a positive result right now; most HIV drugs are just too nasty for ME/CFS
patients - as she said 'you guys are fragile' (more fragile apparently that
AIDS patients (!).
While its not a cure Dr. Klimas has also, like many doctors, found that cognitive-behavioral
therapy is very helpful for improving ones quality of life and getting their symptoms
under control.
She likes Omega 3 fatty acids (4 grams!), COQ10 (look at 120mgs), Isoprinosine
(over the counter Inosine) and Xyrem for sleep. (Each has a section on the website)
Congratulations, again to PANDORA and the CFSKnowledgeCenter for the wonderful
job they did taping this long presentation, editing it and getting it online.

- Dr. Klimas on XMRV - Transcriptions of Her Lecture
- Part I and Part II
Dr. Klimas is giving us new insights into XMRV. Some highlights for me thus far:
the WPI researchers actually found XMRV in virtually every ME/CFS patient
in their study; about 2/3rds of them had an active infection but 30/33 patients
without an active infection were found to have a latent infection; that is, the
virus was found in their cells.
Dr. Klimas is also very clear that this virus is causing the natural killer (NK)
cell and T-cell dysfunction found in this disease. The NK cell dysfunction is pretty
significant since NK cell problems have been consistently found in ME/CFS and I'm
not aware they are connected with other diseases. So XMRV provides a very nice tie-in
with a particular abnormality in ME/CFS.
She also reported that drug companies have literally thousands of compounds sitting
on their shelves that didn't make it to the HIV market but could possibly work
for XMRV.
Ampligen? Ampligen is a possibility - for some patients.
Dr. Peterson has found that it appears helpful in the lab in some patients and not
in others.

- Dr. Bell Talks! - The Daily News, a western New York newspaper had a short piece
on Dr. Bell's talk on XMRV. What did we learn? Dr. Bell expects that we'll see at
least a half a dozen research papers on XMRV over the next six or seven months.
With regards to treatment Dr. Bell noted that "There are pharmaceuticals on the market
that can kill XMRV in a test tube but there are no conclusive studies done to determine
their efficacy on humans". Dr. Mikovits reported the same thing; that there
are anti-retroviral drugs sitting on drug company shelves that they did considerable
research on but which never made it to market but which might be able to be employed
on fight on XMRV. If thats true it gives the medical community a nice head start
on this virus.
Dr. Bell has been able, thus far, to find about 40 of the 60 patients from his original
Lyndonville cohort. He'll be testing them for XMRV in Dr. Ruscetti's lab.
- Dr. Bateman Talks - Dr. Bateman also gave a talk recently on XMRV. According
to someone who attended one of the things that stuck out was how different her patients
were from the patients in the Science study. If you remember the patients in the
Science study were disabled, had RNase L and other immune problems and very low
VO2 max scores on repeat exercise tests. Dr. Bateman reported that while a significant
number of her patients may be tending that way only about 10% of them are currently
that poorly off. Dr. Bateman asked Dr. Peterson at the CFSAC meeting if he thought
the XMRV findings would apply to 'typical' ME/CFS patients but he didn't
to speculate on that. Dr. Mikovits has said, though, that 95% of subsequent tests
on ME/CFS have been positive.
- A new Lab in the Mix - We know (or we hear) that labs across the country are
furiously trying to develop their own XMRV test. Now our source in Utah has identified
one for us. The Hepatitis-Retrovirus lab at ARUP is reportedly 'well into"
developing their own tests. (One of their researchers, Dr. Ila Singh has been studying
XMRV for several years.) Why do we need more tests? We may very well need not them
but the more sophisticated labs that dig into XMRV the better chance that we'll
know more and more about this virus.
Thus far we know of three labs that have taken the XMRV 'challenge'; VIP
Dx (associated with the WPI), ARUP in Salt Lake City, Utah, and Cooperative Diagnostics
in South Carolina. Surely more research laboratories are engaged as well.
Dec 11th
- Dr. Mikovits Grand Rounds Presentation
at the University of Florida College
of Medicine on Oct. 20th. In Grand Rounds p presentations researchers or physicians
simply talk to and get questions from physicians, researchers and students at a
Medical School. In this short article on Dr. Mikovits presentation we find out that
those XMRV positive multiple sclerosis, autism and FM patients the WPI announced
were actually relatives of their CFS patients. Isn't that an interesting fact
in itself: that ME/CFS patients perhaps have a high incidence of MS, autism and
FM in their family. Sure sounds like neuro-immune territory (XAND?).
Check out the article here.
Dr. Mikovits also reported that all the lymphoma patients at the WPI clinic tested
positive for XMRV. (Check out more on the ME/CFS
Lymphoma findings here)

- Podcast on XMRV with Dr. Vincent Racaniello,
the Columbia professor who's
been bloggin on XMRV. His piece on XMRV is about 30 minutes in the futures of Biotech
50 podcast.
- Dr. Judy
Mikovits - the Scientific Director of the WPI (and the one who came up with
the idea to search for XMRV in ME/CFS patients - will do a
live Q&A on Prohealth on Jan 22nd.
-
Article on CFS with XMRV in it
- the CFIDS Association just provided a link
to a Woman's Day article on CFS. Its another good article. I've known for
several years a real change in the media's attitude towards ME/CFS; its hard
to find a bad article on it anymore. Of course the XMRV finding has sped up that
process greatly.
- University of Pacific Talk Embargoed - Just days before the exciting CFSAC
presentations by Dr. Peterson and Dr. Coffin, Dr. Mikovits - the Science director
of the WPI - made what was described as an even more far-reaching 2 1/2 presentation
at the University of the Pacific. A camera crew was there to film it. We were told
it would be a week or two and...that was the last we heard of it. Apparently the
talk has been embargoed by the WPI because it was very far-reaching indeed and they
want to get some more data published before the video is released.
- VIP Dx Labs Slow Pace - Several people have noted that its taking quite a
while to get their test results back and we may have found out why. One of the people
on the Phoenix Rising Forums reported that her doctor checked in and learned that
they are simply because as she put it "they're absolutely swamped".
- Phoenix Rising XMRV Forums - have changed;
instead of one forum we have three: Research and Replication / Test, Treatment and
Transmission and Media, Interviews, Events, etc.
Check them out!

- AZT for XMRV?
A recently released
study examined how effective 10 anti-HIV drugs were against XMRV. The bad
news was that none of the drugs stopped XMRV activity; the good news was that AZT
block XMRV from replicating and from infecting other cells. Thus none of the drugs
touched XMRV while it was in the cell but AZT stopped it from spreading and doing
its mischief once it emerged from the cell.This was a laboratory study which means
the results may or may apply to the more complicated situation in the body.
Follow the discussion on
AZT and XMRV on the Phoenix Rising Forums here.
Dec 7th
- The XMRV Testing Polls
We have a variety of polls running on the
Phoenix
Rising Forums about the results from XMRV testing. They're using Dr. Bell's
Disability Scale to see how people with severe, moderate, mild cases of ME/CFS shake
out. Even though the test has been available for over a month the results are coming
in very slowly. Thus far of 7 people tested using either the VIPDx or the Cooperative
Diagnostics Tests two have tested positive.
Check the polls out here; they're at the top of the page.
Check out some
discussions
on the test results and
why it's taking so long to get results .
Test results should be flooding in pretty soon as the VIPDx starts whipping out
more results and patients get in to see their doctors.
Thanks to the Forum participants we were able to add a few more replication studies
to the list below. There appear to be at least seven pretty well confirmed studies
ongoing.
