UK patient 'free' of HIV after stem cell treatment
A UK patient's HIV has become "undetectable" following a stem cell transplant - in only the second case of its kind, doctors report in Nature.
The London patient, who was being treated for cancer, has now been in remission from HIV for 18 months and is no longer taking HIV drugs.
The researchers say it is too early to say the patient is "cured" of HIV.
Experts say the approach is not practical for treating most people with HIV but may one day help find a cure.
