Two Patients Apparently HIV-Free After Marrow Transplant

Researchers announced that two people with HIV infections are now apparently virus free since they received bone-marrow transplants for lymphoma and ceased taking antiretrovirals, The New York Times reports. These two cases, both in Boston, mirror “Timothy Ray Brown, the famous ‘Berlin patient’ who has shown no signs of resurgent virus in the five years since he got a bone-marrow transplant from a donor with a rare mutation conferring resistance to H.I.V.” Although these cases are not immediately applicable to those infected with the virus, “AIDS experts still find the Boston cases exciting because they are another step in the long and so-far-fruitless search for a cure. They offer encouragement to ambitious future projects to genetically re-engineer infected patients’ cells to be infection-resistant.”
