According to German physicians, it was the world's first type of reaction from a terminally ill patient. A 42 year old, living in Berlin, suffered not only from AIDS but also leukaemia, so he was considered to be a natural candidate for a bone marrow transplant. This type of operation is standard procedure for treating leukaemia, but the doctors also decided to use a special kind of bone marrow, collected from a donor who was genetically immune to AIDS.
Two years after the transplantation, German experts from the Berlin Charite Hospital announced that the HIV virus had not been detected. Previous attempts to do this had proven unsuccessful, so the success of the German scientists could usher in a new series of studies in the treatment of AIDS. So, if previous tests failed the success of German scientists can be the key to whole new idea of treating AIDS. According to estimates, one in a thousand people in Europe and America is genetically immune to the HIV virus.
