Stem Cell Transplants Clear HIV in Two Patients in Study

Two cancer patients in Boston who were also infected with HIV have no trace of the virus after receiving stem-cell transplants, suggesting they may have been cured of the AIDS-causing infection.
The two patients, treated at Brigham and Womens Hospital, stopped HIV treatment after the transplants, which in other patients has opened the door for the virus to come roaring back. In one patient there was no sign of the virus 15 weeks after stopping treatment, while the other has gone seven weeks without HIV rebounding, according to results presented today at the International AIDS Societys meeting in Kuala Lumpur.
The researchers led by Timothy Henrich of Harvard Medical School and Brigham and Womens Hospital said its too early to conclude the two men have been cured and the virus may be lingering in their brains or gut. Still, their cases are similar to that of Timothy Brown, the so-called Berlin patient, who was the first person to be cured of HIV after getting a bone marrow transplant for leukemia in 2007.
While stem-cell transplantation is not a viable option for people with HIV on a broad scale because of its costs and complexity, these new cases could lead us to new approaches to treating, and ultimately even eradicating, HIV, Kevin Robert Frost, the chief executive officer of amfAR, The Foundation for AIDS Research, which funded the study, said in a statement.

Let's hope that there is indeed something to this...it certainly would be a miracle.

The more vocal ones caught on to the different early on because it was important to them.
A lot of others sort of glossed over the difference because, well, effacing the difference was important to them. Or they couldn't wrap their minds around the difference.
These are almost certainly adult stem cell transplants. Probably very similar to the bone-marrow transplant that they modelled the therapy on. No fetuses or anything-blasts were involved in the process.

I won't discount this on limited availability or cost. It's only a few recent cases. The long term is the goal. This may be a step toward that.

(93 posts)bone marrow transplants are not only expensive, they are risky and painful. this is good for advancing science but not a choice that most people would make. The answer in the long run will be finding a way to get the natural immune system to recognize HIV in all its hiding places and eradicate it.
