Scientists draw evidence-based blueprint for HIV treatment, prevention

NIAID Director Anthony S. Fauci, M.D., and colleague Hilary D. Marston, M.D., M.P.H., also note that the results of the IPERGAY study, published concurrently with their commentary online by the New England Journal of Medicine, represent important new data on HIV prevention. The study, conducted in France and Canada, focused on the use of ART for HIV prevention, a practice known as pre-exposure prophylaxis (PrEP). The IPERGAY researchers found that men who have sex with men and transgender women at high risk for HIV infection who took PrEP around the time of sexual activity were 86 percent less likely to acquire HIV than similar individuals who took a placebo. According to Drs. Fauci and Marston, this finding is further evidence of the power of PrEP to prevent HIV infection in high-risk populations. The combination of PrEP and prompt initiation of ART for infected individuals offers a promising blueprint to bring about an end to the HIV/AIDS pandemic, the authors write.

Now, the scientists conclude, realizing the promise of early ART and PrEP depends on whether sufficient global political will can be mustered to provide sufficient human and financial resources to scale up HIV testing and treatment throughout the world.
