I noted earlier the problem that it doesn't spell out the diseases that cause chronic fatigue (such as severe anemia). And I stated it was a loophole (did not not read my email). In my opinion researchers would have to abrogate the understanding of fatigue in disease; certain disorders cause severe, disabling fatigue such as thyroid disease, adrenal disease, multiple sclerosis - others cause fatigue. These disorders are spelled out in the Fukuda definition and its later revision.
They do not include most of the diseases in your list. Now maybe UK researchers are going overboard and excluding everybody with any disease that can cause fatigue. I don't know if that's an idea the ME Community has or if its actually true.
I think its an only intermittently important problem. You can scratch illness and flu and mononucleosis off that list below - the definition includes post-viral fatigue in it(!).
Chronic infection is different. The problem with CFS and chronic infection is that the chronic infections in CFS tend to be those that are difficult to find and diagnose (EBV, HHV6). Most patients do not test positive to standard test of those - so that's not a problem either. Post viral syndrome is obviously not a problem. Hypocortisolism is obviously not a problem since they find hypocortisolism in patients - which suggests that they're not actually excluding every disorder that causes fatigue.
CFS patients are known for going to doctor after doctor and not finding ANYTHING wrong. Most of the disorders below are really serious disorders. I doubt that people with these problems would show up in a CFS researchers office. Do you really expect cancer, lupus, RA, MS, Heart failure, kidney failure, liver failure, crohn's disease, lung infection, etc. to be participating in CFS studies? CFS studies are for people who have been examined to death and nobody knows what wrong with them. Those are the types of patients that make to a CFS research study - not people with cancer or heart failure.
However, I think most of these would be kicked out anyway. The conditions that are excluded because of fatigue have been elucidated in Fukuda and elsewhere; they are far fewer than you suggested. UK researchers know this and are bound by professional integrity to follow those guidelines. I don't think psychiatrists or endocrinologists automatically lose their professional integrity when they pick up their diploma.
The Problem - I don't think this is the problem with the Oxford definition. I think the problem with the Oxford definition is the same problem with the CDC definition but magnified; it allows alot of different types of patients in. Unfortunately until we have some biomarkers and subsets that's the way its going to be. For me that's more than enough cause for alot of concern. That's good enough.
I am not for the Oxford Definition - Please don't interpret this that I am for the Oxford definition. I am arguing more on the basis of technical facts; ie with your interpretation of the problem not that the fact that there is a problem. The Oxford Definition is a big problem in my book. The CDC definition is another BIG problem. I believe the Canadian Consensus Definition, if turned into a research definition, would be a fantastic advance. To some extent we're talking around the edges and agree on the core issue; that the Oxford definition is very problematic.
