A 35-year-old Brazilian man who went into long-term remission after being treated for less than a year with an intensified multi-drug cocktail of AIDS medicines, has raised hope of a potential breakthrough on Tuesday 7 July, 2020.
The man who tested positive for HIV in 2012, was treated with a base of antiretroviral therapy or ART which was boosted with additional antiretroviral, plus a drug called nicotinamide (a form of vitamin B3).
His intensified treatment was halted after 48 weeks and researchers who unveiled their findings at this week’s virtual International AIDS Society Conference, said the patient has now gone more than 57 weeks with no HIV treatment and continues to test negative for HIV antibodies.
Dr Ricardo Diaz of the University of Sao Paulo in Brazil, who led the study said he was “trying to wake up the virus” and boost the immune system’s ability to eliminate it once it’s flushed out of hiding.
Diaz said; “We can’t search the entire body, but by the best evidence, we do not have infected cells. I think it’s very promising. This patient might be cured, but it will take more time to know”.
Professor Sharon Lewin, an HIV and infectious diseases expert at the University of Melbourne who was not involved in the research, said the fact that the patient has no antibodies was significant.
She said: “When someone is infected with a virus they make antibodies. And antibodies don’t budge, even when you’re on treatment and there’s no detectable viral load. But this showed he had no antibodies which is supportive of him being cured.
“It’s interesting, but it’s hard to know how significant it is when it’s just a single case. I’d also like to know what happened to the other patients.”
In the last few years, only two men known as “Berlin” and “London” patients appear to have been cured of the disease after undergoing high-risk stem cell bone marrow transplants to treat cancer.
Several researches have shown that over 75 million people have been infected since the AIDS epidemic began in the 1980s. 33 million people have also died from the virus.
This is remarkable👏
