Researchers Say A 2nd Person Has Been Cured Of HIV

Scientists have potentially cured a person, known as the London patient, of HIV using a stem cell transplant from a donor with a CCR5 gene mutation resistant to HIV. This treatment also addressed the patient's blood cancer. The London patient has been in HIV remission for 30 months without anti-retroviral drugs, although some non-replicating HIV remains. The first patient treated similarly, Timothy Brown, has been HIV negative for 13 years. While promising, this treatment is not recommended for those whose HIV is controlled with drugs and should be a last resort for those with life-threatening blood cancer.

What were the results of the London patient after stopping anti-retroviral drugs?
