Hi, Brenda.
Can you explain the difference please?
***I think this difference arises from the heterogeneity of the CFS population. As you know, CFS is defined by a set of symptoms, and the diagnosis is made by exclusion of other known medical conditions. With this type of case definition, we end up with quite a variety in the people who are diagnosed with CFS. So when small numbers of patients are selected for clinical studies, there can be significant differences found between the groups due to the heterogeneity of the overall population and the resulting statistical variation.
No-one is questioning this. I have been using Jarrow b12 for years for my endocrine system, whichis another reason why I question what Fredd is saying. It was only when I took a massive dose, not the 200 to 400 mics mentioned that I had adverse effects. It is the amount that we have taken that we are questioning. I had a normal blood test result and took b12 for quite sometime before I took the huge dose that Fredd advises. I could not have been deficient.
***I can't speak for freddd, but I will address this from the point of view of the Glutathione Depletion--Methylation Cycle Block hypothesis that I have proposed to explain the etiology, pathogenesis and pathophysiology of CFS. According to this hypothesis, the problem with B12 in CFS is that glutathione has become depleted, leaving the B12 unprotected at a certain stage in its processing inside the cells. As a result, one can have a blood serum B12 test that comes out in the normal range, but still not be able to use B12 functionally in the cells to carry out its jobs. It has been found in autism, and we have also found in CFS, that it is necessary to raise the dosage of B12, and to take it together with one or more reduced forms of folate, in order to overcome this functional blockage and restore the methylation cycle and the glutathione levels to normal. This is apparently necessary to overcome the loss of B12 to reactions with toxins, which take place when it is unprotected. I originally encouraged PWCS just to elevate glutathione directly, but this did not turn out to be a successful longterm treatment. It was only when I learned of the success in autism that I realiized that the methylation cycle block must be treated to allow glutathione to come up on a permanent basis.
***With regard to the conventional blood serum B12 test, it is meaningful in cases in which the people are actually deficient in B12, and have been for an extended time. However, it is not very meaningful in CFS, where the issue is usually not lack of normal amounts of B12, but rather is the lack of proper B12 function. A better test in CFS is the urine methylmalonic acid test. This test will show whether enough adenosyl B12 is being made in the cells, because its lack will cause methylmalonic acid to rise. Usually if there is not enough adenosyl B12 being made, then there is also not enough methyl B12 being made, because they share the part of the pathway that involves protection of B12 by glutathione, through the formation of glutahionylcobalamin. An exception is the small number of people who have an inborn error of metabolism that affects only the formation of adenosyl B12, but this is a fairly rare genetic disorder.
***Normally, most of the B12 in the blood is carried by haptocorrin, and this part of the B12 is not accessible to cells other than liver cells. A smaller part is normally carried by transcobalamin. If a conventional serum B12 measurement is made, it does not distinguish between these two parts, and that is another problem in interpreting the results of this type of measurement.
***With regard to having adverse effects from larger dosages of B12 (together with reduced forms of folate), I think it is important to try to determine how adverse the effects are. The Simplified Treatment Approach that I have proposed is somewhat different from the protocol freddd has suggested, but when people first started using it 3 years ago, there were a small number of them who indeed had rather severe adverse effects. I have posted these in the past on this forum. This is the reason I insist that people should be working with their physicians while on this treatment. In some cases, the people involved had other comorbid conditions that were apparently responsible for the adverse effects, including autonomous multinodular goiter and autoimmune diseases. For the majority of people, who did not have such comorbidities, there were usually some unpleasant symptoms, which I believe are associated with die-off of pathogens and mobilization of toxins into the bloodstream. These last for differing lengths of time, presumably depending on the body burdens of infections and toxins that the person has accumulated.
***freddd and I seem to have different philosophies in our approach to these symptoms. My view is that it is best to lower the dosages of the supplements to levels that make the detox and die-off symptoms tolerable. It will take time to clear these out of the body. I wish it were faster, but times of at least two years do not seem to be unusual for someone who has been ill for an extended period of time. I do not have proof that this approach is better in the long run than "pushing through" the symptoms by continuing with the high dosages. It just seems to me that going more slowly is a wiser way to proceed at our current state of knowledge. Also, I think people are more likely to stick with the treatment if they do it at a level where the symptoms are tolerable. If a person stops the treatment because it is intolerable, there is no chance that the treatment will help them. If they continue with it, success is not guaranteed, but at least there will be the opportunity to see if the treatment will in fact help them.
In direct contradiction of both of these studies Fredd claims
Well this opinion just shows us how little Fredd knows about hypothyroidism and Hashimotos.
***Again, I think it's important to keep in mind the heterogeneity of the populations we are dealing with. I focus particularly on CFS, and the numbers I have given apply to CFS. freddd's treatment approach applies to a much broader population, including not only those with CFS, but also those who have any of a wide variety of problems in their B12 biochemistry. These can include B12 deficiency in the diet (such as in pure vegans), hypochlorhydria, lack of secretion of intrinsic factor or inability to recognize intrinsic factor in the ileum (pernicious anemia), intestinal disease such as Crohn's disease or celiac disease that interfere with the ability to absorb B12 bound to intrinsic factor, surgery that has removed the terminal ileum, transcobalamin deficiency, and any of several inborn errors of metabolism that affect one or more of the B12 processing enzymes in the cells. So when freddd cites prevalences, I think he is basing them on a broader population.
***The reason freddd's approach applies to this wider range of disorders is that he uses large dosages of the final, coenzyme forms of B12, and he applies them sublingually or by injection. This bypasses all of the B12 absorption, transport and processing pathways, and delivers the final forms of B12 directly to the cells. In the treatment I have proposed, the form of B12 is hydroxocobalamin, and this must be converted by the cells into the coenzyme forms. So this treatment does not bypass the function of the cells in regulating the amounts of the coenzyme forms that are produced.
I have no problem with anyone sharing what helped them and answering questions but I do have a very big problem with anyone who is not medically qualified and who displays a lack of understanding about Hashimotos to the extent that he confuses it with hypothyroidism, and makes the previous statement and when a growing number of desperate people try his protocol and have a reaction that is beyond detoxing or starting up or anything else (does he think that after years of this we do not know what a Herx is?) and he tells us to KEEP GOING instead of at that point saying I AM NOT MEDICALLY QUALIFIED TO ADVISE YOU IF YOU ARE HAVING SUCH A BAD REACTION YOU MUST SPEAK TO SOMEONE ELSE .
This is in my opinion VERY DANGEROUS.
***Again, I can't speak for freddd, and I have described my philosophy about this above.
We are being expected to accept that the two people here who are agreeing with each other that cannot be dangerous, know more on the subject than we sufferers do due to their understanding of the views of certain researchers yet the forums which have been mentioned for Hashi sufferers contain warnings about taking b12 supplements slowly. There is a lot of disagrement in the endocrinal world and we sufferers often have to go it alone and listen to our own bodies. So now we have two people telling us who have had a very bad reaction and mine was so bad that I was suicidal for a few days and I have been ill for a very long time with mercury poisoning and Lyme disease a combination that is hard to beat in terms of suffering, and the reaction to the b12 was more than I could take or had ever experienced before.
***I'm very sorry about the reaction you had to the treatment you tried. I wish we had a great deal more research completed, so that we would know exactly what the optimum treatment would be for each person. Unfortunately, we are still in the research stage with CFS, and we are having to feel our way with whatever information we can find. And having Lyme disease on top of it makes it very challenging.
All I ask is that when another person like us comes along and reacts like we have that they be told by Fredd that he cannot advise rather than what he is doing encouraging them to go on and telling them that what their body is saying most strongly, that their adrenals and thyroid cannot take the strain, is incorrect instead of overiding their concerns.
***Again, I can't answer for freddd.
The continuation of this issue which has been going on for quite some time, is causing me serious concerns about what is going on here. The fact that Fredd is actually encouraging people to continue instead of allowing them to do so without any outward pressure with NO MEDICAL QUALIFICATIONS regarding a condition which must be handled with extreme care, is what is being addressed but not emphasised enough.[/QUOTE]
***I think I've expressed my suggestions about how to respond to symptoms above. Again, my position is that a person needs to be working with a physician while on the treatment I have suggested, so that if serious adverse affects arise, they can be properly dealt with immediately. With regard to determining whether a reaction to the treatment is severe enough that the treatment should be stopped completely, I suggest consulting with a physician about that. If the symptoms appear to be due to detox and/or die-off, then I suggest that the person, together with their physician, decide whether proceeding at lower dosages would be advisable.
***I want to emphasize that I am a researcher, not a clinician. My focus is to try to understand the biochemical mechanism of CFS. The hypothesis I have proposed gives guidance for developing treatment, but it does not lead us directly to the optimum treatment, and I can't claim that the treatment I have suggested is the very best approach. I extracted it (with the help of a person who has CFS and is on the Yasko treatment) from the full treatment program that Amy Yasko, Ph.D., N.D. uses primarily for autism. I hope that in the future we can learn more about how to optimize the treatment. A small number of physicians who specialize in treating Lyme disease have incorporated testing for the methylation cycle block and treating it if it is found. However, this is only part of their treatment for Lyme disease.
***I also want to emphasize that I favor testing prior to deciding whether to undergo methylation cycle block treatment, using the methylation pathways panel offered by Vitamin Diagnostics, Inc. in the U.S., and by the European Laboratory of Nutrients in the Netherlands. Running this test will indicate whether a person has the biochemical abnormality that the treatment is designed to correct, and it will also provide baseline values for a number of parameters, which can be used to gauge the progress of the treatment. Evaluating whether the treatment is helpful based on symptoms can be difficult initially, because of the symptoms that I believe are due to detox and die-off of pathogens. So having lab-measured numbers can tell you whether progress is being made or not, until the symptom picture clears up, which may take some time.
***I hope this is helpful, and I hope you will be able to find an effective and tolerable way to treat your illness.
***Best regards,
***Rich
