I don't think words about intuition and emotion ("feel") have any place in a scientific study.
Could it be a non-xenotropic murine retrovirus, or an endogenous human retrovirus? I don't know, I'm wondering, too.But what would these virsues be? I thought human retroviruses were incredibly rare, or is it just diseases-causing retroviruses that are believed to be rare.
In the explanatory material for the WPI study that was published later, they said that the samples were blinded, so they wouldn't have known if a negative sample was a control or a patient and they should have treated the same. And yes, Judy Mikovits did say that they sometimes had to test samples more than once, using different methods, to get a positive.As for contamination and explaining the difference in WPI positive rates for patients vs controls, one possibility did occur to me, though I may have got this wrong: I seem to remember Judy Mikovits saying they often had to test samples several times to get a positive results (please tell me if I got this wrong). Were controls retested too i.e. if a control was negative was it reteseted? If not, patients would automatically have more chance of positives.
There are lots of things wrong with this study, more than the quote above, though that certainly counts and is central to my criticism.
Did Singh actually prove that she could even detect XMRV in a bona fide CFS patient to begin with? I wonder. That, to me, should be a fundamental requirement BEFORE funding a study for Pete's sake. That makes me wonder about the folks that funded this flawed study as a reflection of these results. Who would such underwriters serve with this as their results? Not me.
She proved that she could detect a contaminant a small percentage of the time. What does that have to do with the discussion at hand? The "conclusions" drawn rest on really flimsy and, to my mind, unscientific thinking. A la the "feeling" remark. Well I have some feelings about this whole debacle, not just this one study but the parade of negative studies since the Science paper that I will touch on below.
This whole thing smells to high heaven of exactly the same politics that sank the DeFreitas study way back in the early 90's. And with the same players no less. What is that quote about learning and paying attention to your history so as not to repeat it?
This drum roll of negative studies sounds pretty much the same to my ears. If and when anyone actually stands up and actually REPLICATES the WPI study, then I'll pay attention.
I think that headline is accurate - based on what they said in the study. They actually didn't say XMRV is not associated with CFS; they said 'they feel that' XMRV is not associated with CFS.
I would be surprised if they if f XMRV in the blood does not turn out to be associated with CFS.
Logically you're correct - you cannot say XMRV is not associated with CFS until you look at all the tissues - but you can say that about every pathogen. The question is whether its an important question? I don't think it is.
There's no reason to think XMRV is hiding away, undetectable in the blood but still virulent in the tissues of people with CFS. Remember the WPI was rather easily able to detect XMRV in the blood of ME/CFS patients in the Oct. study and has been able to do that since then - as has VIP Dx labs. They find it in the blood ALL THE TIME.
It's not as if XMRV somehow appeared in the blood of that first set of patients (and in all the people who have tested positive since then) by the WPI and then disappeared into the tissues of every other person with ME/CFS who tested negative in the other studies.
Nor is the WPI saying you have to search for it in the tissues - they are saying that we can find it in the blood, we find it in the blood every day and you - the negative studies are doing something wrong.
Every study has to show that they can detect XMRV. Unless you have a person proven to have XMRV then you don't have the basis for showing that you can detect it in humans and the whole problem has been proving somebody has XMRV. That would require validation by several laboratories and as yet that has not happened. a
If you think Dr. Singh - a retrovirologist who was actually studying XMRV in prostate cancer before she studied it in CFS - is playing politics please give some facts that back up that assertion. DeFreitas finding was studied by the CDC, at least two diagnostic labs, and Dr. Levy (and I'm sure some others)...Over 20 labs have published papers on XMRV and that doesn't count non-published lab work or the outstanding studies. The degree of work on XMRV is magnitudes larger than that done on De Frietas.
I'm not sure what you mean by replicating but if you read the other comments you'll see that Singh did replicate the culture study and used the same assays as the original paper did.
All the negative studies are playing politics. Just think a little about what is at stake here. If these guys can prove that the WPI study is wrong, well, they can then have a little race to the wire with who WILL find it and then you're looking at patents and drugs and research money.
The whole field of medical research is one of the most cut-throat political arenas out there, right along with the academic side of things. To not see that is to be truly attached to your rose colored glasses.
I'm sure that individuals that do this work have altruistic intentions at least part of the time but the whole thing is driven by the great god money and its handmaiden academic recognition. Who in these fields don't dream of the Nobel prize, for example? It's beyond competitive and very nasty the further "up" the food chain you go.
Just because someone is a retrovirologist doesn't mean they're some version of a beneficent god smiling on us from behind the goggles and holding up a test tube.
As for what happened to the DeFreitas study, have another peek at the meticulous history taken by Hillary Johnson in Osler's Web. It's quite enlightening in regards to what is happening now. Only some of the names have changed, certainly not the methods.
And by replicate I mean REPLICATE. That means full and total adherence to the methods and protocols done in the first study. That means cooperation, FULL cooperation and transparency with the original study members and labs. Period. This has NOT been done yet to my understanding.
Everyone so far has had their own methods, reagents, etc. Not one study has actually troubled themselves to rigorously, humbly avail themselves of the opportunity to actually, fully REPLICATE.
The stakes are high - for a little idea of how high have a look at the vast money and resources garnered by the HIV research and drug sales folks. There are arguably more people with CFS than HIV so do the math.
I really disagree with the idea that these studies are playing politics. This is science, they don't 'vote' for their results, they measure them. Yes, a few of the negative studies involved researchers involved in ME/CFS politics but for the most parts the studies have been been sincere efforts to help CFS patients. But I agree the stakes are high, the incentive to find XMRV is huge for everyone, including WPI. Strong enough for WPI to keep promoting XMRV even when the evidence is now so strongly against their theory that many journals are not interested in publishing more CFS XMRV studies, positive or negative.
There is no rational incentive for any of the labs to not find XMRV. There might be conspiracies against CFS patients in some areas, perhaps the insurance industry and a few government agencies have in the past sought to down-play the seriousness of CFS. But given the market size for any product that could successfully treat CFS, there is incentive for ALL of the labs to find something, anything at all that they can prove.
Based on published research now, XMRV is most likely a complicated contamination event. People can accept or reject that, but it is the emerging scientific consensus.
I think the sooner we collectively get back to basics and demand the fundamental type of research needed for CFS (starting from square one, the 'flu-like illness' and other triggers and what they can do to a person with CFS preconditions), the sooner we will get on track to really solve CFS.
But given the market size for any product that could successfully treat CFS, there is incentive for ALL of the labs to find something, anything at all that they can prove.
Krizani: Excellent post...thank you for your eloquence and clarity.
Because I still love you kjm and I'm trying to get just a taste of that beautiful spark we once shared.Asleep -- why come to a forum you seem to despise so much.
I don't see anywhere that an open discussion of XMRV is not allowed by Cort or Kurt.
People here can think for themselves and they do.
For a few minutes, I honestly thought I was reading a post on that other forum.
Excellent posts Krizani!
In case you are new to this forum, I will fill you in on a little secret. The purpose of this forum is not to engage and promote honest discussion about XMRV. In fact, it is is quite the opposite! This forum serves primarily to manufacture a picture of consensus and certainty that XMRV is dead and that it is time to move on.
Cort and Kurt are the gatekeepers of this illusion and serve to promote the interests of the CAA/CDC by trying to prematurely steer the ME/CFS community past XMRV.
The truth of this is readily transparent if one observes a few basic facts:
- Any post that is pro-XMRV or XMRV-agnostic or attempts to demonstrate flaws in the negative studies will always and immediately be followed by a post from Cort and/or Kurt that tries to undermine it, not address it.
- Despite personal assurances from Cort/Kurt to the contrary, their posts are consistently riddled with fallacious arguments, unsubstantiated assertions (e.g Kurt's claiming to know what "scientific consensus" is or what everyone's intentions are), opinions dressed as fact (Kurt: "Based on published research now, XMRV is most likely a complicated contamination event"), vague allusions to insider knowledge, etc. They rarely address the points made in the original post (and when they do it is with bald assertions, illogical arguments, gut feelings, or false "evidence" conveniently "misremembered" or "misunderstood"). Rather, they attempt to deflect or emotionally bully people away from supporting a fair trial for XMRV.
- These posts have time and time again been demonstrated by many to be flawed and diversionary for the reasons I touched upon and more. But these criticisms, if ever acknowledged, are never heeded and the onslaught of these posts proceeds unabated.
- These posts inevitably revolve around one or more of the following anti-XMRV talking points:
- Anything but XMRV (e.g. "ME/CFS might be caused by a (retro)virus, but it is certainly NOT XMRV"). In essence, it's not the man behind the curtain so please stop looking in that direction.
- The researchers of negative study X have no reason not to find XMRV (assertion, not fact).
- The researchers of negative study X are of the highest caliber and should have found XMRV if it was there (assertion, not fact).
- XMRV is easy to find and should be found with any methods researchers want to use (assertion, not fact).
- Negative study X was a "replication" study (none of the negative studies to date have duplicated the WPI's methods, including Singh's study, and therefore are not replication studies).
- True replication isn't necessary to disprove XMRV association (simply false and dangerously unscientific).
- Reports of improvements on ARVs are irrelevant because they are anecdotes and probably due to the placebo effect (in any other context these anecdotes would at least be considered worthy of preliminary exploration).
- Unsupported insinuations about the original Science study: e.g. speculation on how contamination occurred w/o any direct evidence and in spite of it being partially blinded.
- Conspicuous omission of any discussion of Lo/Alter. If pressed on the issue, the study will be immediately dismissed as "not a replication". It is certainly not acceptable to propose that it is actually a validating study. It's interesting that, in this context, people all of a sudden remember what a replication study is!
- Various non-sequiturs based on false premises: e.g. "There are plenty of other promising lines of research" (implies the false premise that XMRV is over), or "XMRV did bring lots of attention to the disease" (again implies false premise that XMRV is over and gives the appearance of having been objective about it), or "Will these researchers continue to study ME/CFS after XMRV?" (again, false premise and feigned objectivity).
- (Probably others I'm forgetting)
- Together, these talking points are used to illogically justify a premature and unscientific dismissal of XMRV based on insufficient and poorly designed research. For added effect, it is often made clear that questioning these talking points is "conspiracy theory" or "inappropriately divisive" or "disrespectful" or some other form of intimidation. You are advised to sit down, be quiet, stop asking questions!, and let the CAA guide you through many more decades of murky nonsense.
Today I'm feeling grateful that the authors of this study put so much time and effort and care into it. I'm grateful that they are taking CFS seriously enough to study it.
Whether XMRV turns out to be related to CFS or not, I'm grateful to Judy Mikovits for her courage in proposing this idea. It was a bold move. I appreciate that she is working so hard to try to solve the puzzle of our disease.
I'm grateful to Ian Lipkin and Alter and Lo and Ruscetti and all the other scientists who are looking into physical causes of CFS.
I hope we are now out of the dark ages of CFS and are permanently in an era of improved research and attention and funding and effort to help us.
No matter what happens with XMRV, I still believe that the WPI is one of our best hopes for finding solutions.
