USING HIV DRUGS TO PREVENT INFECTION WORKS, ELIZABETH TRACEY REPORTS
A two drug combination taken daily in men at risk to become infected with HIV largely prevented infection with the virus, a recent study in the New England Journal of Medicine found. Joel Gallant, an HIV expert at Johns Hopkins, lauds the study.
GALLANT: This was a very large study, one of many that’s going on using a variety of difference drugs used to treat HIV. In this case they were using them to prevent HIV transmission. The drugs clearly worked. Those people who took more of it, took it more adherently, had the best results. This is not necessarily surprising but it’s the first time we’ve seen this kind of effect of antiretrovirals as prevention of sexual transmission and it’s pretty groundbreaking news. :26
Gallant says that surprisingly, some men who reported taking the drugs weren’t actually doing so, as evidenced by blood tests. He says that until a better understanding of risk taking behavior emerges developing an effective vaccine remains our best strategy. At Johns Hopkins, I’m Elizabeth Tracey.
