I am not able to read through all the comments, so forgive me if I'm repeating anything. But some of the things I found so frustrating about the paper:
Not only do they say that 75% had gradual onset unrelated to an infectious agent, or that half had not seen a doctor, but that only "about 16% had been diagnosed with CFS."
How ludicrous is that?
Does that not mean that approximately 84% of the subjects in this study population had not been diagnosed with the very disease the CDC claimed to be studying? That would be like doing a study on MS, where only 16% even had MS .
Further, they say: "The physical findings in persons meeting the Canadian definition may signal the presence of a neurologic condition considered exclusionary for CFS and thus the XMRV positive persons in the Lombardi et al. study may represent a clinical subset of patients."
Are they not aware that 1) ME/CFS is classified by WHO as a neurological condition and 2) the Canadian Consensus Criteria already excludes those with MS and other neurological diseases.
Further, if they are indeed saying there may be a cohort who do have XMRV, are they now studying that cohort? Something tells me not.
It's all so maddening.

CFS can be gradual onset. Are you saying only sudden onset can be XMRV? I don't think anyone knows that, in fact the monkey study showed that even extreme XMRV infection (injected into the blood!) is not likely to cause any sudden change in health (in an animal model).
There may be some serious issues with the CDC study, but there are also still serious issues with the XMRV hypothesis.
The CDC focuses on epidemiology, and therefore they wanted to know in their earlier studies what percent of the population had CFS. So this is not a valid criticism of the study, although I know people here are saying it is. They gave medical exams and in essence diagnosed those people with CFS according to the definition used at that time by the CDC. Therefore according to the CDC, everyone in their study had diagnosable CFS.
Dr. Reeves is no longer using Fukuda. He is using his own method for establishing a population on which to base the world’s research on Chronic Fatigue Syndrome. And he has been telling us this all along – in his own way.
The new definition was announced in a backwards fashion. We know that the patients in the genome study were chosen from the Wichita study – but others also were given the questionnaires that Dr. Reeves has created to define Chronic Fatigue.
As I pointed out last fall, these same questionnaires proved to be disastrous failures in diagnosing patients with CFS or charting improvement when used in the Ampligen double-blind studies.
I have never been a fan of the Fukuda definition, mainly because cognitive dysfunction and post-exertional fatigue are the hallmarks of this disease, and it is possible to be diagnosed with CFS-Fukuda without having either. Nevertheless, there was an effort to include physical symptoms.
But Dr. Reeves told us in April that patients with CFS do not have cognitive dysfunction. (They are just tired.) Nor did they have problems with sleep. At least, not anything that would distinguish them from other patients with "chronic fatigue."
He had just announced to us all that two of the eight possible physical symptoms of CFS according to Fukuda were meaningless. And in doing so, he had told us he was now using a different definition for CFS.

Cloud said:I don't understand giving the CDC benefit of the doubt on ANYTHING to do with their motives and actions in regards to ME/CFS. They have a history of proven lies and illegal activity in regards to ME/CFS (fact) and they have not demonstrated any attempts at redemption by doing the right thing since. In fact, they appear to be continuing right on down that same corrupt path they've been on for many years. I'm an optimistic person by nature and, I tend to see the good in people and situations....but I know one can never trust a fox in the hen house regardless of how convincing the varmint presents it's case. If the CDC appeared to act in our favor, my first thought would be....what's the catch.

They got away with this in the late 1980's but that ain't gonna happen again - not on my watch. There are far too many people (the sick, advocates, Congress, other health orgs, researchers, scientists, physicians, and so on) that are watching and we have the Internet and its super fast power to move information.
