HIV: early treatment, the key to remission

People living with HIV need to take antiretroviral treatment for life to prevent the virus from multiplying in their body. But some people, known as "post-treatment controllers", have been able to discontinue their treatment while maintaining an undetectable viral load for several years. Starting treatment early could promote long-term control of the virus if treatment is discontinued. Scientists from the Institut Pasteur, the CEA, Inserm, Université Paris Cité and Université Paris-Saclay, in collaboration with Institut Cochin and with the support of MSD Avenir and ANRS Emerging Infectious Diseases, used an animal model to identify a window of opportunity for the introduction of treatment that promotes remission of HIV infection: it appears that starting treatment four weeks after infection promotes long-term control of the virus following the interruption of treatment after two years of antiretroviral therapy. These results highlight how important it is for people with HIV to be diagnosed and begin treatment as early as possible. The findings were published in the journal Nature Communications.
