American doctors manage to cure a woman with HIV for the first time
An American has become the third person and first woman possibly cured of HIV, after undergoing a stem cell transplant from a donor with natural resistance to the virus that causes AIDS, a novel treatment that may open treatment options. heal more people. She announced this Tuesday during a conference held in Denver (Colorado, USA) by the team of specialists who treated her in New York.

The patient, they explained, has not had detectable levels of HIV for fourteen months despite having stopped treatment with antiretrovirals, so she is considered to be free of the virus and will be considered cured if there are no changes. She would become the third person in the world to be cured of the virus and the first woman, since the two known cases so far were men.
Known as the "New York Patient", to maintain her anonymity, she was first diagnosed with HIV and then with leukemia. The woman received a stem cell transplant from an umbilical cord, supplemented with adult cells donated by a relative.
The technique is similar to that used in the case of the two known cures so far, which is based on the use of stem cells from individuals who have a genetic mutation that makes them resistant to HIV, but according to experts the use of cells from an umbilical cord instead of an adult donor is considered a major potential advance.
According to the scientists, using blood from an umbilical cord does not require the same level of donor-recipient compatibility that is required for adult cells, which may make this type of treatment beneficial to more people.
In any case, experts warn that the cure for HIV through stem cell transplants is still limited for now to cases in which the patient suffers from cancer or another serious illness that justifies a very complex and potentially fatal procedure.
As Deborah Persaud, the specialist at Johns Hopkins University who directs the program within which this research has been carried out, told NBC channel, stem cell therapy "remains a feasible strategy for only a handful of the millions of people living with HIV".
The team responsible for the treatment at a New York hospital also stressed the importance of the "New York Patient" being a person of mixed race, since the genetic mutation that makes someone resistant to the virus usually occurs in white people, which which until now has made it difficult to find compatible donors for people of other races.
