	Source:* Time* AUTHOR: Meredith Melnick http://healthland.time.com/2011/02/28/an-anti-hiv-gel-shows-some-promise-for-prevention/ A new study presented Monday at the annual Conference on Retroviruses and Opportunistic Infections (CROI) in Boston suggested the potential of an anti-HIV gel in protecting rectal tissue cells from infection with the virus that causes AIDS. The gel made by Gilead Sciences Inc. contains the antiretroviral drug tenofovir, which, when applied in the vagina in previous trials, reduced HIV infection by 34% compared with placebo. Researchers have wanted to know whether the gel could protect against anal transmission of the virus, since the risk of infection from unprotected anal sex may be more than 20 times that of unprotected vaginal sex. In part, that's because the rectal wall is one-cell thick, compared with the multiple layers of vaginal walls. For the new study, researchers from the Microbicide Trials Network, University of Pittsburgh and Magee-Womens Research Institute recruited 18 sexually abstinent HIV-negative men and women to participate. The volunteers were first asked either to apply the anti-HIV gel to the rectum once or to take an oral tenofovir pill once. Then, the patients followed up by applying either tenofovir gel or placebo gel every day for six days at home; a final, seventh dose was applied in the lab.
