If the results hold up, it will be the second time in history that doctors have reportedly cured H.I.V. — though the procedure remains so prohibitively expensive, complex, and dangerous that it might not lead to a reliable treatment for the scourge.
In a paper published Tuesday in the journal Nature, the researchers describe how they performed a bone marrow transplant into an unidentified patient using stem cells from a donor with a rare genetic mutation that causes a resistance to H.I.V.
Now, 18 months after the patient stopped taking anti retro viral medication, doctors say there’s been no sign of a return of the infection.
