Thanks for posting. Would love to know the latest with Cheney's research on stem cells but I don't have a subscription to his newsletter.
This guy had cancer & HIV. Therefore he needed a bone marrow transplant to treat his cancer. That requires immune system ablation--ie chemo to reduce your immune cells, transplant new donor cells that repopulate your immune system, and therafter take immunosuppressants for life so you don't "reject" the donor cells. Yes, they used a donor lacking the receptor that HIV binds to on the cell. One percent of Caucasians lack this receptor.
This does not apply to XMRV. In HIV work they are now trying gene therapy and other methods to downregulate this receptor as a way of treating HIV. So it gives insights. Perhaps someday they can do that with other viruses. But this means little for anybody who has CFIDS.

New stem cell treatments in Panama have rapidly slowed and perhaps justifiably so after the increasing realization that several trips and perhaps annual trips may be necessary, even for the best responders, to maintain any peak benefit. I think this is due to the high incidence of XMRV re-activation under either stressors or immune activation such as an infection (flu season) or allergy season as was the case with my step-son (he relapsed with allergy season). He did respond very well to the second transfusion and is back in school so it was worth it to us but we can afford multiple trips if the benefit is so dramatic. He also failed to do anything other than the stem cells after the first trip because he felt cured after this initial visit. The cost of having him miss school is even more expensive over time so it even made economic sense. He is now on the typical regime all my patients are on including Artesunate and CSF’s/HPE. When we get to a better anti-viral strategy (ie Artesunate titration, GcMAF, Transfer Factor or Peptide-T) using the GFP-LNCaP quantitative assay, we can optimize it and my hope is that this will prolong the benefit as well as enhance the benefit of stem cells, at least for those under 60. I am not as sure about stem cells for those over sixty and not altogether sure why this is so but significant reservations also apply to those over sixty receiving organ transplants as there appears to be a rapidly declining benefit curve with age, especially over 60, for almost any therapy. This was also seen in the U. of Colorado stem cell treatment of Parkinsons 15 years ago. Those over sixty responded very little to stem cells in contract to those under 60. It may simply be harder to make an over 60 year-old twenty again but much easier to make a twenty year old with CFS feel twenty again. There is the possibility though that anti-viral strategies may work well in those over sixty as well. We will see. Right now, I can only strongly recommend stem cells for those under 35 and only under the proviso that they may need additional trips over time to maintain benefit. Those over 40 but under 60 will likely see less of a response to stem cells compared to those under 35 and may also need repeated visits to maintain their peak benefit. Those over 60 should probably wait until we can optimize this very promising therapy but it is their call. All stem cell patients should use our current anti-viral recommendations as well as CSF support which does seem to improve the level of response to stem cells and helps prevent early regression.
Thanks for the added information.
So do you dispute the concerns many have that getting stem cell infusions with XMRV present could just end up reinfecting the new cells with the retrovirus? Or that for stem cell therapy to work with XMRV, the immune system might need to be ablated to prevent that from happening?
The two are completely unrelated.
First of all, the receptor that HIV initially binds to, is a redundant receptor. So the 1% of Caucasians who lack it don't suffer, as they have other receptors to do the same work.
The likelihood that XMRV is binding to a redundant receptor initially--who knows? And that 1% of the population lacks that receptor? Who knows.
That's why it worked as they used a donor lacking that receptor. In addition, it is not a viable therapy for folks to go thru chemo to wipe out their immune system, get donor bone marrow, and then be on immunosuppressants the rest of their lives. You haven't seen this as any kind of universal therapy for HIV, have you?
It gives insight into the virus, and so scientists are working on ways to either use gene therapy to alter/disable the receptor, OR drugs to downregulate it and hobble HIV. That is the usefulness of this example of this one case.
It has nothing to do with Cheney's stem cell therapy, where you just get stem cells. It's just a whole different ball of wax. I've seen people bring up this HIV study repeatedly with absolutely no understanding of what was involved.
Joey, you make a really good point -- but if xmrv binds to only one receptor on initial cell entry it had better be redundant or you can't downregulate it.
As to the ? Regarding regular stem cell therapy for Cheney patients I have no comment. All I'm saying is the Berlin patient's situation was totally different and not relevant to the Cheney treatments.
Jen, the point of the thread has nothing to do with the cheney stem cell treatments. The treatment the HIV patient received and the cheney stem cell treatments are two different things. They are not related, and there is no implication of any relevance or correspondence of the HIV treatment and the cheney stem cell treatments. That's why I posted it in the "Other Health News and Research" section.
If anything, the implication in fact is exactly the opposite: that the cheney stem cell treatments probably are not going to work for XMRV any more than a similar kind of stem cell infusion would work for HIV, and that for stem cells to work for XMRV they perhaps would need to be engineered as the article mentioned the researchers were trying to do in the effort to combat HIV.
Iow, the thread in effect is saying, "it's interesting that a full transplant cured the HIV case and that they are working on engineering the stem cells to target HIV better. Perhaps the same approach would be necessary for XMRV." No mention or relevance of this story to the completely different technique cheney uses in the Panama clinic was stated or implied, except perhaps in the negative sense I just described, i.e., noting that the cheney treatment doesn't work for XMRV.
Hope that helps clarify that this thread isn't about the cheney stem cell treatments, regards.
stem cell treatments alone would not work because you need the chemotherapy to first destroy the immune system along with the retrovirus before laying down stem cells to make a brand new and clean immune system free of disease causing pathogens.
I thought I just said that?
