Hi Cort,
IMHO. I'm not so sure that we need to spend more money on research when we have info like this article listed below available. Simply making this known would eliminate much of the confusion around PEM and CFS. IMHO, Articles such a the one referenced in this thread or other articles where questions like this are raised that already have answers only add to the idea that we don't know what's causing PEM when in fact, IMHO we do know how this happens. Correcting PEM is a whole other bucket of worms especially if Cheney is correct and those with PEM also have dysautonomia.
I found many other articles like this while googling CFS Cheney peroxynitrate ... We know more than we think we know ... : ) .. Thank you google !
I only copied in page 5 and most of page 6 but to understand this you need to start on page 1.. FWIW. I see Dr. Cheney and Dr. Myhill as saying the same thing ... Loss of ATP = PEM. Cheney just goes into further detail on how he thinks this happens. I would think that by the looks of the Kreb's cycle that this can happen at various other points too. I say this because it appears that taking the B12s that Fred recommended have lessened my PEM. KOW ... I want to avoid the "I'm Feeling better" curse ... lol ...
I found it very interesting that Cheney understands that our bodies are going into organ failure when we're upright. I knew this from my own experience because when I lay down after being upright for an extended period of time, I can feel the blood going back into the organs in my upper body ... I have orthostatic intolerance and have to lay down every few hours in order to think straight or take a deep breath. After laying down for an hour, I ALWAYS have to urinate right away when I get up. And while laying down I can actually feel my lungs and heart muscle begin to relax as the blood, etc re-enters these organs. I can take a deep breath again. If you don't have OI, try holding your breath and pay attention to how your body feels as you allow the air to re-enter your lungs so you can understand this. Or pay attention to how any part of your body feels as it wakes up from the loss of blood aka falling asleep.
Note to self ... Don't eat BBQ chicken at 9 pm if you want to sleep ... lol ... I sure hope this all makes sense ... good night ... X

What is CFS if it is not ME and a wastebasket diagnosis? The Canadian criteria used the term ME/CFS because it was for ME patients, CFS was included in the term because people in the USA and now in the UK can no longer get an ME diagnosis. Therefore PEM was an issue that Ramsay mentioned. He was even talking about mitochondria problems as early as 1977, if not earlier.
That's one reason, Recovery Soon, I think this disease is so fascinating - something really happens. For me it happens more quickly -but generally builds up until it is worse the next day....I wonder if its histamine for you. Some findings implicate the complement system, one section of which trips off a histamine reaction. Maybe something in exercise makes that portion of the complement system go crazy in you
There is something terribly wrong when we have known that there is a mitochondria problem for more than 30 years, and yet little progress beyond this conclusion has been attempted. I don't think there has been any other convincing explanation for PEM than mito problems.
I've seen little overweight old ladies - carrying 20 or so extra pounds of fat, just yakking away, enjoying the scenery - while there I was, 20 years younger, lean and looking as fit as could be - just struggling to put one foot in front of the other...its ridiculous! Its absolutely crazy!
Well Ramsay and others thought it was probably the case, that was in 1977. It's merely a matter of research. There has been too little, and too much of it has been wasted were it should not to have been.
Hi Cort,
My crazy moment was getting off a bus and walking up a hill to my flat. A hundred meters, total. Around the corner came a very old lady in a walking frame. She passed me by, and accelerated up the hill and away. She almost had a fiendish grin on her face - huh, someone I am faster than! - and she was gone before I got to my flat. That was post exertional malaise, it was when I was studying to get my last degree.
People have been pointing to the mitochondria for well over a decade in the circles I am aware of. A lot has been discovered by CFS doctors but not published. I think Cheney tried to get a few papers published but he had great difficulty - I think reviewers were of the opinion that he had been hit with the crazy stick. Once you are considered to have opinions that are extreme, publication becomes close to impossible.
For example, the recent publication that relapses are linked to vitamin E depletion (oxidative stress) came as no surprise to me. One local CFS doctor routinely tests vit E levels and can't even find vit E in some CFS patients - a zero result! This is of course unpublished, but now we at least have the Japanese study that shows the problem. Oxidative stress is critical to CFS and PEM, and is very closely linked to mitochondrial function.
As an aside, I suspect that lactic acid is a good thing for us unless we become excessively acidic - because lactic acid helps energy production. I have never heard of a CFS patient developing lactic acidosis, which is the really dangerous thing that can happen when you have too much lactic acid.
Bye

Great stuff and I too think dysautonomia and orthostatic intolerance are key facets of this disorder. (I the CAA has a webinar coming up on OI). I wonder if OI is as key a part of this disorder as PEM actually. PEM is more noticeable for me and I apparently past a tilt table test (altho Dr. Cheney said that not all the tests were done) but I felt horrible afterwards and I often try to sit down or lie down when I talk to people because I can talk better (more blood to the brain) and when I was working I had quit several jobs because they required that I do a lot of bending up and down - so I think its there and present even in those of us with more moderate cases of CFS.
I think your post, though, makes my point about research. Dr. Cheney got his initial ideas from Dr. Natelson's research group at the NIH. After the NIH disbanded the three CFS research centers about 10 years ago the work on the cardiac involvement in CFS completely stopped. That's 10 years lost! Over the past couple of years a little work has been done but the scientific community will never believe the heart or any other organ is involved in CFS in less papers are published in scientific journals.
For the all creativity and perseverance that Dr. Cheney has shown he's never apparently attempted to publish his theories in a medical journal. Nor, unfortunately, as he attempted to publish his results. So his theories have never been properly explored and haven't had any impact in the scientific community at large. (Neither has Dr. Peterson for that matter. Unfortunately he is no longer tied to the WPI I don't imagine that he will)
Mitochondria, mercury and other heavy metals and I'm sure there are others exemplify the huge divide between many ME/CFS doctors and the research world. I don't think there's been one study that looked at heavy metals and CFS. I'm also certain that mercury plays a role in CFS for me - but not one study has looked at that. Its kind of amazing that a disconnect there is.
I would entirely agree that there's been far too little research on this and other theories - why we all need to band together and support everybody who's working in this field.
Its been 13 years since Cheney published anything and even then he was a co-author because he was contributing patients to the study. What we're really missing are papers elucidating his own theories and showing his own results. Last year a mother of a child with CFS got her theory published in a review journal; if she can do that then Dr. Cheney certainly could. Real studies are alot harder to pull off - but at the very least I would think a theory paper is appropriate. He's got alot of interesting ideas - it would great to see a formal paper from him.
Hey I think gut problems could do it; in fact one of the CAA's intertwined group of studies puts gut problems right smack in the middle of the whole thing.
