For the second time in the history of medicine, a "cure" from HIV has been officially recognized, although it is more correct to speak of "functional healing". The London patient, whose name has not yet been released, received a stem cell transplant from a donor who was immune to the disease and after 18 months of observation, his blood was no longer showing signs of the virus. This is not yet a cure for HIV, but it is already a big victory.
The main thing in this news was that the first case of HIV healing, at last, is no longer considered an isolated success. The working method and scientists hope in the near future to carry out dozens of experiments and operations aimed at improving technology. But, nevertheless, the widespread use of the method and the natural salvation of mankind from HIV is not yet to be expected.
The problem is in bone marrow donors with HIV immunity, which also have to be compatible with the recipient - this is a very rare combination. Plus, the operation and the associated procedures are so risky that even in countries with developed medicine, mortality from such an intervention is very high. In other parts of the world, the operation is not available at all.
It is more economically feasible to develop antiretroviral therapy, or to cast aside doubts and focus on genetic modifications. The object for work is known, it is the CCR5 gene, which needs to be blocked. And the donor of bone marrow stem cells for the London patient was found virtually by accident, the presence of a useful mutation in him became a real gift, which was used by the doctors.
