OK, brain totally scrambled now - thank goodness for autocorrection in word. No more today.
Lecture by David Bell 8:21 to 14.22
The psychiatric issue thats been going on for years is characterised in this slide. As I understand it the web will not be able to see the slides and I guess I will be able to get away with it. I showed this slide at a lecture I gave in 1987 at the University of Rochester School of Psychiatry. University of Rochester has a world famous school of psychiatry and the auditorium was filled with interns and residents. I showed this slide and silence, just silence. (laughter) Its been a misperception that somehow this illness must be a psychiatric illness and heres where modern medicine has made a big mistake. Doctors are under the government. If you go into the doctor and the doctor has no idea of whats going on with you hes got to come up with a diagnosis, whereas in the old days that wasnt true. The doctor could just say I dont know what you got but now they cant do that for some reason I cant quite understand why and theyll say I cant find anything wrong. Your livers normal size, your blood tests are fine therefore you must be depressed. And this is really quite unfortunate because psychiatric diagnoses have very strict criteria. If you are depressed you usually know that you are depressed. Depression has severe hopelessness, it has all these symptoms that are not part of Chronic Fatigue Syndrome. So for years theres been this ongoing controversy is this illness due to a psychiatric basis and doctors have been kind of mystified and they say I dont know what you have but I dont want to deal with you so I want you to go and see the psychiatrist. And this has very unfortunate consequences for patients. Because this is whats happening in the psychiatrists office (laughter at a slide we cant see) and really when you try to look at the specific , again at the University of Rochester they didnt like this slide (laughter) They were very negative about this slide . I was trying to say, you know this was just a joke (more laughter). But psychiatrists really would have a difficult time explaining the theory of how some viral infection causes some inactivity and then that inactivity gets into a cycle that leads to orthostatic intolerance and these other things because there is no model that really explains it in the psychiatric literature.
Now thats not to say that psychiatric disease cannot coexist with Chronic Fatigue Syndrome and this is a very important point. For those people who have Chronic Fatigue Syndrome and who are depressed well youve got to address that. And its actually fairly easy to address. The antidepressants work very nicely on the depression when it coexists with Chronic Fatigue Syndrome but it really doesnt help the symptoms of Chronic Fatigue Syndrome once youre well. Many people are reluctant to admit their depression because they then will say, well maybe the psychiatrists were right, and thats a mistake. If there is depression going on then youve got to address it and this is no different than if you had multiple sclerosis or HIV disease or any other organic illness. If you get depressed because of the severity of the illness youve got to address that and that becomes fairly easy to treat as part of the illness. But it doesnt remove the basic symptoms of Chronic Fatigue Syndrome.
OK, tonight were going to be talking about XMRV and this was some of the interesting or exciting new information thats come out. The definitions here, XMRV stands for Xenotropic Murine Retro Virus, more accurately its Xenotropic Murine Leukemia Related Virus and this is a fairly large family of retroviruses that XMRV is part of. A retrovirus is a specific type of virus which is an RNA virus, very small compared to other viruses and its able to insert itself into the human chromosome and from there it replicates itself and causes damage. Xenotropic the word means that its able to jump species. Many years ago back in the 1990s this was thought to just never occur among retroviruses and one of the big arguments in HIV history is could this have come from the simian immunodefficiency virus, the SIV. Did it actually jump species and become a human pathogen? Xenotropic means yes, it definitely does, so this virus was first described probably many years ago in the retrovirology in different animals and thats where doctors have been able to study this for many years and its only recently become clear that this is a human pathogen.
