HIV cure, a less uncertain journey

Feb. 27, 2023
By Mar de Miguel
HIV research is a winding road where one obstacle leads to another, slowing down success. The first barrier to getting the cure starts before one can even talk about it. “Cure may be too powerful and promising a term. Remission is probably better,” said John Mellors, whose work led to the universal use of plasma HIV-1 RNA and CD4+ T-cell counts in HIV-1 infection.

“Cure means maintaining an undetectable viral load off antiretroviral treatment. That means you cannot transmit it to people. Within that definition, there are people that have complete eradication of every single virus. And then, you have people that have a low level of virus that are able to keep under control without drugs,” Sharon Lewin told BioWorld. “Remission is maintaining a viral load less than 50 copies per milliliter in the absence of any retroviral. But there is still virus detectable,” she explained. Lewin is the director of The Peter Doherty Institute for Infection and Immunity in Melbourne, and the president of the International AIDS Society (IAS).
