Fact or Fiction: Does circumcision help prevent HIV infection?
Lundi 01 Décembre 2008 - 08:00 - 1 mois, 1 semaine depuis - Presse spécialisée - Scientific American The male foreskin--an unassuming flap of skin eagerly discarded in some cultures--has taken center stage in recent debates over HIV prevention. Although researchers now agree that its removal is a proved method to reduce HIV spread in heterosexual men, the picture for homosexual men remains a bit foggy.In the late 1980s observations of heterosexual men in Africa indicated that those who had been circumcised might be at less risk of contracting HIV than men who left their foreskins intact. To definitely test the hypothesis, researchers initiated clinical trials in at-risk populations with low rates of circumcision. [More] |

Can HIV Infection Be Prevented with a Once-Daily Pill?
Lundi 01 Décembre 2008 - 06:00 - 1 mois, 1 semaine depuis - Presse spécialisée - Scientific American JOHANNESBURG, SOUTH AFRICA--Nearly four years after political pressure shut down two trials that would have tested whether a once-a-day pill could prevent high-risk HIV-negative people from catching the AIDS-causing virus, there’s a surge of renewed interest in the concept, known as Pre-Exposure Prophylaxis, or PrEP.Western doctors and organizations that funded the halted trials of the anti-HIV drug tenofovir in Cameroon and Cambodia say they've learned their lesson from the debacle in 2004 and 2005, when activist groups questioned the quality of medical care impoverished study participants would receive if they suffered side effects or the became infected by HIV. Today, with at least seven U.S.-funded PrEP trials underway at a cost of $39.5 million, researchers are working with local advocates, who have traditionally been distrustful of Big Pharma, to push the studies forward.

Protecting Women from HIV--Docs Hopeful About Microbicides
Lundi 01 Décembre 2008 - 05:00 - 1 mois, 1 semaine depuis - Presse spécialisée - Scientific American Antiretroviral (ARV) drugs have transformed HIV infection from a death sentence to a manageable chronic illness for millions worldwide. Now, scientists are testing whether ARVs can be used as microbicides, taken orally or applied vaginally as a gel or foam to prevent the transmission of the AIDS-causing human immunodeficiency virus.If ARVs are proved as effective as microbicides, they have the potential to dramatically curb HIV infection rates. This is especially true in sub-Saharan Africa where women, who comprise nearly 61 percent of the adults living with HIV there, are eager for products besides condoms that they can use to protect themselves against the disease.

The U.S.'s $18.8-Billion Global AIDS Initiative--5 Years Later
Lundi 01 Décembre 2008 - 04:00 - 1 mois, 1 semaine depuis - Presse spécialisée - Scientific American SOWETO, SOUTH AFRICA--The Perinatal HIV Research Unit (PHRU) at the sprawling Chris Hani Baragwanath Hospital here is abuzz with activity. Young women with swelling bellies wait in plastic chairs to see nurses while pharmacists distribute antiretroviral drugs from an office behind a metal security gate. Upstairs, a fresh coat of paint is being applied to the walls of a new men's clinic that offers HIV-testing, support and treatment.In the late 1990s PHRU pioneered research into using antiretroviral drugs to prevent and treat HIV, the virus that causes AIDS, in developing countries. Today, it is a model of how funding from the U.S. President's Emergency Plan for AIDS Relief (PEPFAR)--more than $18.8 billion since 2004--has radically changed the global fight against AIDS and helped put more than 1.7 million people, mostly in Africa, on life-prolonging antiretroviral treatments who otherwise would likely have died.
