London man becomes only second person ever to be ‘cured’ of HIV as scientists hail breakthrough
A London man became the second person to be ever cured of HIV after undergoing a stem cell transplant. An unidentified man in the UK received bone marrow stem cells from a donor with a rare genetic mutation that resists HIV infection, 18 months ago. The man has lived 18 months after he stopped his HIV treatment without any sign of virus returning. The tests show no sign of man’s previous HIV infection.
In 2003, the London man was diagnosed with HIV. He did not start taking drugs to control his infection until 2012. Later in 2012, he developed Hodgkin lymphoma. In 2016, the doctors suggested him a stem cell transplant to treat cancer. His doctors believed that with the right kind of donor, he could find an HIV cure as well as cancer treatment. His doctors found a donor with a rare gene mutation. It gives a natural resistance to HIV. The transplant changed the London man’s immune system completely. With this transplant, he received the donor’s HIV resistance.
The London man became the second person in the world after Timothy Ray Brown from the US, to have been cleared of HIV virus. Till now, Timothy Ray Brown went through a stem cell transplant in Berlin 12 years ago. The doctors said that despite the patient seems “functionally cured”, but it is too early to say he’s cured.
