Marrow may hold key to eliminate HIV

Doctors say they can no longer detect the Aids virus in two American patients who underwent a bone marrow transplant to treat their cancer diagnosis.

Doctors in Boston stop short of calling it a cure. The two male patients underwent bone marrow transplants to treat lymphoma, but in the process received bone marrow that was free of HIV. They kept taking their HIV drug cocktail, which researchers say kept the new bone marrow from becoming infected. Now they have stopped taking the drug cocktail and have no traces of the Aids virus in their bodies. The doctors say they’ve been HIV free for four years.
