Just saw my doctor today, he is a virologist that specialises in HIV. We were talking about the hiv positive guy who also had leukemia and had a bone marrow transplant. After which he was hiv neg. The talk in the medical circles is that even if the donor wasnt hiv resistant, if the man had survived the operation, he would still be hiv neg. Becos the doses of the drug they used to kill off his entire immune system is twice that of the dose that they used in the US. Basically they killed off all of his T cells, all of them. They basically starved the HIV virus to death. No more cells to feed on, the virus dies. A less dangerous operation would be to use chemo drugs to kill off the cells while taking ARVs at the same time. This will achieve the same purpose. Unlike cfs, they already know exactly where the hiv virus hides. Ironically they are trying the chemo and ARV approach first with cfs patients and the drug Rituximab.
