This (well similar) technique was also been reported to technically cure HIV. Over the years there have been several incidents[e.g. 1] where people with HIV also had cancer such as leukemia in which the treatment was the kill the bone marrow and do a transplant.

Since for the procedure the bone marrow is wiped out as well as most of the immune system the HIV virus could not replicate within the T-Cells.

If those cases maintained a strict anti-viral regiment they would so far be pretty much HIV free (dormant vira as well as common HIV infection of the digestive tract cells would still be an issue).

This is unlikely to be used as any form of an official procedure tho the risks are simply too great without an actual proof that this even works in the long term.

Wont surprise me tho if some people might evolve this to a limited treatment especially if a bone marrow donor with natural HIV immunity can be located.

I was wondering the same thing myself. Also, isn't re-building the immune system dangerous in the sense that it increases the patient's risks to certain types of blood cancers?
