Second HIV Patient Achieves Long-Term Remission Through Novel Treatment
A second patient enters long-term HIV remission following a bone marrow transplant, proving a cure is possible. While the risky procedure is not a broad solution, it sparks new hope for future genetic therapies.
A second patient achieves long-term remission from HIV twelve years after the first documented cure, according to a new report in the journal Nature. This milestone proves that curing the virus is possible, though scientists emphasize that significant obstacles remain before a broad treatment develops. Researchers present these promising findings at the Conference on Retroviruses and Opportunistic Infections in Seattle.
The successful treatment involves bone marrow transplants that doctors originally administer to treat the patients' separate cancers rather than the HIV virus itself. Because these transplants carry severe risks and dangerous side effects, they do not serve as a viable widespread cure for the millions living with HIV. Existing medications successfully control the infection for most patients, making the extreme transplant approach unnecessary for general use.
Despite the dangers of the procedure, scientists see immense potential in the underlying mechanism of this cure. The treatment relies on mutated immune cells containing a specific variant of the CCR5 protein, which physically blocks HIV from latching onto host white blood cells. Researchers hope to use this discovery to develop safer therapies that replace infected cells with genetically modified immune cells that resist the virus, proving that a cure is not just a dream.
