Two men given bone marrow transplants no longer have any HIV virus detectable in their blood, creating hope that researchers could be closing in on a cure for the disease that causes AIDS, reports ABC News. The transplants occurred while both men were undergoing anti-retroviral therapy, suggesting that the two treatments together could hold the secret to a cure.
"We expected HIV to vanish from the patients’ plasma, but it is surprising that we can’t find any traces of HIV in their cells," said one of the doctors. The case is similar to the man who was cured of HIV after getting stem-cell therapy for leukemia, but, as the bone marrow transplant patients are still taking their anti-retroviral medications, doctors are not yet 100% sure whether they are completely cured. Doctors also note that bone marrow transplants are expensive and too dangerous for many HIV patients. (Read more HIV stories.)
