An American research team reported that it has possibly cured HIV in a woman for the first time. Building on past successes, as well as failures, in the HIV-cure research field, these scientists used a cutting-edge stem cell transplant method that they expect will expand the pool of people who could receive similar treatment to several dozen annually.
Their patient stepped into a rarified club that includes three men whom scientists have cured, or very likely cured, of HIV. Researchers also know of two women whose own immune systems have, quite extraordinarily, apparently vanquished the virus.
Carl Dieffenbach, director of the Division of AIDS at the National Institute of Allergy and Infectious Diseases, one of multiple divisions of the National Institutes of Health that funds the research network behind the new case study, told NBC News that the accumulation of repeated apparent triumphs in curing HIV “continues to provide hope.”
“It’s important that there continues to be success along this line,” he said.
In the first case of what was ultimately deemed a successful HIV cure, investigators treated the American Timothy Ray Brown for acute myeloid leukemia, or AML. He received a stem cell transplant from a donor who had a rare genetic abnormality that grants the immune cells that HIV targets natural resistance to the virus. The strategy in Brown’s case, which was first made public in 2008, has since apparently cured HIV in two other people. But it has also failed in a string of others.
