A Brazilian man with AIDS has shown no indication of the virus that causes the disease for more than a year since he stopped taking HIV medicines, after receiving intense experimental therapy aimed at eliminating the virus hidden in his body , the doctors reported on Tuesday.
The case needs to be independently verified and it is too early to guess about a possible cure, the scientists said.
"These are exciting results, but they are preliminary," said Dr. Monica Gandhi. , an AIDS specialist from the University of California, San Francisco. "This happened with one person, only one person" and not with the four others who received the same treatment, he added.
Another UCSF specialist, Dr. Steven Deeks, said: "It is not a cure," just a Interesting case worthy of further study.
The case was described at an AIDS conference in which researchers further revealed an important advance in prevention: one injection of an experimental drug every two months was more effective than Truvada daily pills. to prevent uninfected gay men from contracting HIV from an infected sexual partner. Hundreds of thousands of people take these preventive pills now and the injection would give them a new option, almost like a temporary vaccine.
If the Brazilian case is confirmed, it would be the first time that the virus has been eliminated in an adult without a bone marrow or stem cell transplant. The independent experts want to determine if the remission lasts that the combination of medications in the therapy he received is used in more tests.
"I am very excited because it is something that millions of people want," said the 35-year-old man, who spoke to The Associated Press on condition of anonymity. "It is a gift of life, a second chance to live."
The transplants were like two other men, nicknamed patients "Berlin" and "London" by the places where they were treated, they were previously cured.
"I am living proof that it is possible to be cured, "said Adam Castillejo, the" London "patient, during a press conference at the AIDS meeting, which is being held online due to the coronavirus pandemic.
He and the “Berlin” patient Timothy Ray Brown had donors with a gene that confers natural immunity against HIV. These transplants are very risky and impractical to be attempted on a large scale, so doctors study other methods.
