The journal The Lancet HIV reported that Adam Castillejo, London, has become the second person to be ever cured of HIV. He was previously known as "London patient." The 40-year-old was first diagnosed with HIV in 2003. He underwent a special bone-marrow transplant. After that, he had been free from HIV for 18 months. After 12 months, now, he indeed represent a cure.
The first patient to be cured of HIV is Timothy Brown. He is also known as the Berlin patient. He received a similar bone-marrow transplant in 2007. He has been HIV-free for more than 10 years now. The stem cells used for the transplants (of both Adam Castillejo and Timothy Brown) was from a donor who had a relatively rare genetic mutation that confers resistance to HIV. The researchers stated that bone-marrow transplant would not work as a standard therapy for all patients with HIV. A stem cell (or bone marrow) transplant is a procedure that will replace defective or damaged cells in patients whose normal blood cells have been affected.
