Guest guest Posted March 25, 2003 Report Share Posted March 25, 2003 , My impression is that this was written quite a long time ago. The most recent reference cited is dated 1993, and Dr. Cheney is said there to be in Charlotte. He hasn't practiced there in a long time. I doubt that he would still subscribe today to what he wrote then, though I can't speak for him. From my point of view, increasing the intake of carbohydrates, including fructose, would not be beneficial for most PWCs. The problem with it is that in my opinion the Krebs cycle has partial blockades, and can't handle processing the pyruvate that comes from glycolysis of carbohydrates at a high enough rate to keep up. As a result, the pyruvate either gets converted to lactate or not, but both of them have to be either burned by tissues that can burn them (such as heart muscle) or they have to be processed by the liver, via gluconeogenesis, to make glucose, which is returned to the blood. There's no way to get rid of the excess glucose other than to convert it to stored fat, which causes weight gain. So eating more carbohydrates is not such a good idea, in my opinion, for most PWCs, and I suspect that Dr. Cheney would agree with that today. Rich > Hi Rich, > In a paper found at http://dspace.dial.pipex.com/comcare/docs/me0048.txt Cheney says the following: > " Mitochondrial dysfunction and loss of dominant ATP or energy generator would obviously result in an up-regulation of anaerobic metabolism or glycolysis to compensate.....It is noted that this system runs on carbohydrates and especially fructose. It should be no surprise then that CFS patients crave carbohydrates. If they eat fat, they cannot consume it in the mitochondria, due at least in part to acylcarnitine deficiency, and therefore fat storage increases as does body weight. Serum cholesterol and triglycerides increase in some individuals...An obvious approach would be to increase carbohydrates and reduce fat intake. The use of fructose combined with chromium to improve its entry into the cell might also improve ATP generation. " > > You have said that it is difficult for PWCs to burn carbohydrates and fats as fuels and have hypothesized that a process called anaplerosis allows amino acids to get by the blockages in the Krebs cycle to provide fuel that is missing with the loss of the carbs and fats. So protein becomes the fuel of choice. Because so many PWC do well on high protein diets, this sounds good to my struggling-to- understand, non-scientific mind but it doesn't seem to square with what Cheney says. Or does it? I couldn't find a date for the Cheney info and wonder if it might be a dated piece of information with more research done since. Could you fill me in on this? > > Thanks a lot. > > > > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 26, 2003 Report Share Posted March 26, 2003 Hi, Jim. Thanks for your comments. I'll make some in response below: > > Hi , > > I know that you had directed your question to Rich but I thought > I'd assist. > > Your question is a good one. > > If pyruvate cannot be processed quickly enough due to blockages in > the mitochondrial processes, the excess pyruvate is converted to > lactic acid. (If this conversion is not done the cell could run low > on NAD+ and then glycolysis could become blocked. Pyruvate + NADH - -> > lactic acid + NAD+) Whether or not this conversion happens depends on how well the mitochondrial shuttles can keep up with the production of NADH in the glycolysis, which takes place in the cytosol, outside the mitochondria. If the shuttles can't keep up, the cells perform anaerobic glycolysis, producing lactate. If the shuttles can keep up, then the cells operate on aerobic glycolysis and produce pyruvate. > > (Note: This is where I see CFS and FMS differentiate.

In CFS this enzyme is > able to carry out this function and hence there is an increase in > lactic acid. This is described in the presentation on my website at > http://www.xmission.com/~total/temple/index.html) I don't think it is as clearcut as that. I realize that Eisenger et al. reported elevated pyruvate in PWFs. Some PWCs seem to have a higher degree of lactic acid production than others, which I think is evidenced by a burning sensation in the muscles with little or even no exercise. Others don't seem to experience this. There's also a range of response to alcohol, which I think has its effect in CFS by shutting down the Cori cycle. Some PWCs are devastated by this, indicating that they are very dependent on the Cori cycle. Others can tolerate alcohol pretty well. This either means that they are not relying on glycolysis and the Cori cycle as much as the others, or that their livers have larger capacity to process alcohol and still keep up gluconeogenesis to complete the Cori cycle. I'm not sure which. Some of the cases I've studied who can handle alcohol alright were pretty hefty drinkers before they got ill, and maybe they " trained " their livers to have a higher capacity. I'm not sure about this yet. > > The lactic acid from the cell is transported via the bloodstream > back to the liver, where the lactic acid is converted to glycogen. > The glycogen is essentially taken out of circulation until there is a > need for more glucose.

Under normal conditions, you're right, this is the way it works. However, in PWCs who continue to consume carbohydrates above their cells' capacity to completely burn it up, I think they will soon exceed the liver's capacity to store glycogen. It can hold about 8 to 10 % of its wet weight as glycogen, according to my biochemistry textbooks. The buildup of glycogen acts as a regulatory mechanism to limit its further buildup. Once the glycogen storage is at capacity, the liver has no choice but to dump the glucose back into the blood, where the elevated insulin will eventually push it into fat cells to make stored fat out of it. There are diseases called glycogen storage diseases in which the amount of glycogen stored in the liver can rise higher than this. This produces hepatomegaly (enlarged liver), which can be seen by ultrasound exam of the abdomen. While some PWCs do have hepatomegaly, I don't think that most of them do, so I don't think the normal glycogen storage limits are usually exceeded in PWCs. > > There is not an increase in blood glucose levels from this > recycling of pyruvate. Well, I guess we differ on this point. The glucose does rise, and if the pancreas is working properly, it puts out insulin and pushes the excess glucose into the fat cells, so that it doesn't rise to dangerous levels. > > However, due to the blockages in the mitochondria it is possible > that blood glucose levels remain elevated for a longer time.

Guest guest Posted March 26, 2003 Report Share Posted March 26, 2003 Hi Rich, Thanks for filling in the gaps in my explanation. I agree with you that the blocks to mitochondria processes must be removed. And, glutathione may do this in time. However, per Cheney's presentation in Dallas a couple years ago, he diagrammed how glutathione production follows the production of ATP. The conclusion I drew from that was that until ATP production increases, glutathione production will remain low. Enzyme levels are likely low inside the cells, add to that the lower body temperature associated with CFS/FMS (due to low ATP) and metabolism is severely impaired. I think that raising the body temperature helps restore a little metabolism for a short while, so that some of the cellular processes may take place and produce more ATP. This will help with production of glutathione (that is if production is limited by insufficient ATP). I agree with your dietary suggestions. However, with the high protein diet if HCl production is reduced in the stomach then complete protein breakdown may be impaired. If a leaky gut situation exists this may create an allergic response to the food. Your thoughts and corrections are appreciated. All the best, Jim > > > > So what can be done to help?

Guest guest Posted March 26, 2003 Report Share Posted March 26, 2003 Hi, Jim. Thanks again for the comments. I don't recall Dr. Cheney saying that. I think it's the other way around, i.e. you have to raise the glutathione to remove the partial blockades in the Krebs cycles, due to elevated peroxynitrite, in order to raise the production of ATP. I'll have to go back and look at the tape. Do you mean the one from 1999 or the more recent one? Concerning the stomach acid deficiency and the leaky gut issue, I agree that they have to be dealt with before good digestion and absorption can take place, and to knock down the food intolerances. Those are some of the reasons I agree with Dr. Corsello on treating the G.I. issues up front, as I said in my " Strawman Treatment Protocol, " which put in the Links section of this list. Concerning the heating, that does seem to help people, particularly the PWFs. I'm not sure what the mechanism is, though. Improved blood perfusion may be part of it. At the Orthomolecular Health- Medicine Society meeting a while back I tried out an FIR tunnel for 10 minutes myself. It really seemed to help a sore muscle in my back! I got the sensation of the deep heating you have talked about.

Guest guest Posted March 26, 2003 Report Share Posted March 26, 2003 Hi Rich, The Cheney tape that I have is the one that was distributed by the Dallas CFIDS group. I think it was either 1999, or 2000. I'll watch it again to make sure I heard it correctly, it was about 3/4 into the presentation. I'll take a look at the strawman treatment protocol, I had been meaning to ask for more info on that. All the best, Jim Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 28, 2003 Report Share Posted March 28, 2003 Roxy, I'm wondering whether you might have a leaky gut, that has produced some food sensitivities. Have you been tested for food sensitivities, such as with an ELISA-ACT test or by an elimination diet? How about leaky gut? Have you had an intestinal permeability test?

Guest guest Posted March 30, 2003 Report Share Posted March 30, 2003 Annette, I think it would certainly be worthwhile trying to build up your folic acid level. A dosage in the range of 400 to 1,000 micrograms per day would probably be beneficial. Absorption of folic acid supplements is best if taken on an empty stomach. Folate in food is only absorbed at about 50%. Here's some information about folic acid in CFS: Folic acid participates in the synthesis of DNA, RNA, and proteins. It is involved in DNA replication and repair, maintenance of the integrity of the genome, and regulation of gene expression. Folate deficiency produces megaloblastic anemia. Other symptoms and signs of folate deficiency are weakness, fatigue, irritability, headache, difficulty concentrating, cramps, palpitations, shortness of breath, and atrophic glossitis. The similarity of this list with the list of symptoms found in CFS prompted a search for folate deficiency in this disorder. son et al. (1993) and son (1994) measured serum folate in 60 patients who met a set of criteria based on the criteria for CFS of Holmes et al. (1988) and Sharpe et al. (1991). These measurements were initiated on the basis that earlier work by son et al. in viral and mycoplasmal infections had shown low serum folate. They reported that 50% of the patients were found to be deficient in serum folate, and an additional 13% had low borderline values. A review of their diets did not reveal low folic acid intakes. On the other hand, Regland et al. (1997) found normal levels of serum folate in 24 women who satisfied both the Holmes et al. (1988) criteria for CFS and the ACR criteria (Wolfe et al., 1990) for FM. It is not clear why the results of these two studies differed. Bengtsson et al. (1986) tested the serum folate levels in 36 primary FM patients who met the Yunus, Masi, Calabro, , and enbaum (1981) FM criteria, and found normal levels in all of them. Kaslow, Rucker, and Onishi (1989) evaluated the effect on patients who met the Holmes et al. (1988) criteria for CFS of intramuscular self-injections of an extract of bovine liver together with added folic acid and cyanocobalamin. The daily dosage was 800 micrograms of folic acid and 220 micrograms of cyanocobalamin equivalent. Fourteen patients participated in a crossover study in which all received one week of the treatment and one week of placebo. In addition, eleven 11 patients completed a follow-on open-label treatment that lasted two more weeks. Although significant improvements in functional status and symptoms were found with both the treatment and the placebo, the former was not found to be more effective than the latter. As Werbach (2000) has pointed out, the dosage and duration in this trial were much smaller than those successfully used to treat depression and fatigue in cases of folate deficiency (Botez, Botez, Leveille, Bielmann, & Cadotte, 1979; Godfrey et al., 1990). In the first of these, the dosage and duration were 10,000 micrograms per day (orally) and two to three months to relieve fatigue and depression. In the second, 15,000 micrograms per day were given orally for six months. Rich > Hi list, > > I've been following this discussion with great > interest.

Guest guest Posted March 30, 2003 Report Share Posted March 30, 2003 Roxy, Great Smokies lab (http://www.gsdl.com) has a test called Intestinal Permeability Assessment. You drink a solution of lactulose and mannitol, and then collect urine for six hours. By looking at the ratio of lactulose to mannitol in the urine, they can get a measure of how leaky your gut is. Most food sensitivities are not Type 1 IgE mediated allergies. Rather, they are delayed types 2,3 or 4 sensitivities. These require a different type of test, such as the -ACT test (the website is http://www.parentsofallergicchildren.org/elisa_act_test.htm and the e-mail address is clientservices@...) This test is not cheap, but some people are able to get it covered by insurance. I don't see how hypercoagulation would cause the response to the diet that you described. It seems more likely to me that you have a leaky gut and are responding to one or more foods in the diet by developing food sensitivities as the immune system responds to large protein fragments that leak into the blood stream. Another thing you could try would be to rotate your menu so that you don't eat the same food for a week in between. If delayed sensitivities are being developed, this should prevent it from happening. In the long run, though, if you have leaky gut, the thing to do is to fix your gut. If that turns out to be the case, I think that Dr. Corsello's bowel treatment protocol is a good one. It's described in her book, " The Ageless Woman, " available from http://www.corsello.com Rich > Rich, > > Thanks so much for your response.
