An AIDS patient is apparently free of HIV after receiving a bone marrow transplant during leukemia treatment.
The patient, a a 42-year-old American living in Berlin receiving stem cells from a donor with that a genetic mutation, making him immune to HIV, the virus that causes AIDS. Two years on, doctors say the patient has stopped taking AIDS drugs and HIV cannot be detected in the patient's blood. But they warn this is not treatment that can be used for all AIDS sufferers, and is not a cure for the disease.
