HIV returns in two US men after bone marrow transplants

WASHINGTON (AFP) - Signs of HIV have returned in two American men who appeared to have briefly eradicated the virus after bone marrow transplants for cancer, US doctors said on Friday.

Experts said the discovery is a disappointment to efforts to find a cure for the human immunodeficiency virus behind Aids, but offers important new clues in the hunt for the disease's elusive hiding places.

Only one person is believed to have been cured of HIV. American Timothy Brown, who suffered from leukaemia, received a bone marrow transplant from a rare donor resistant to HIV and has shown no sign of the virus for six years.

"The return of detectible levels of HIV in our patients is disappointing, but scientifically significant," said Dr Timothy Heinrich, a physician-researcher in the Division of Infectious Diseases at Brigham and Women's Hospital in Boston.
