The woman, treated with virus-resistant stem cells from umbilical cord blood, is one of only a handful of people experts think have been cured of HIV.
is expected to join this group—all of whom beat the virus after receiving bone marrow transplants from donors naturally resistant to HIV.
As the mutation conferring HIV resistance is rare—though less so among white people—and stem cell donors must be carefully matched to patients, including by race and ethnicity, researchers said it is very difficult finding suitable, HIV-resistant donors for patients of color. Stem cells from umbilical cord blood are both more readily available and do not need to be matched as closely as adult cells do, which “broadens the opportunities” for people of all racial backgrounds living with HIV to be cured, said study co-leader Yvonne Bryson, a professor of pediatrics at UCLA.
Though certainly a game changer for people who need a transplant already, the researchers stressed stem cell transplants are not a realistic cure for HIV on its own given the procedure’s risky, highly invasive nature and brutal side effects.Barring the unique circumstances of a very small number of people, there is no cure for HIV.
