NYTimes.com: "In a development that could change the battle against AIDS, researchers have found that taking a daily antiretroviral pill greatly lowers the chances of getting infected with the fatal virus.
"In the study, published Tuesday by the New England Journal of Medicine [full text], researchers found that the hundreds of gay men randomly assigned to take the drugs were 44 percent less likely to get infected than the equal number assigned to take a placebo.
"But when only the men whose blood tests showed they had taken their pill faithfully every day were considered, the pill was more than 90 percent effective, said Dr. Anthony S. Fauci, head of the division of the National Institutes of Health, which paid for the study along with the Bill and Melinda Gates Foundation.
"'That’s huge,' Dr. Fauci said. 'That says it all for me.'
"The large study, nicknamed iPrEx, included nearly 2,500 men in six countries and was coordinated by the Gladstone Institutes of the University of California, San Francisco.
"The results are the best news in the AIDS field in years, even better than this summer’s revelation that a vaginal microbicide protected 39 percent of all the women testing it and 54 percent of those who used it faithfully.
"Also, the antiretroviral pill — Truvada, a combination of two drugs, tenofovir and emtricitabine — is available by prescription in many countries right now, while the microbicide gel is made only in small amounts for clinical trials. ...
"Because Truvada is available now, some clinicians already prescribe it for prophylaxis, Dr. Fauci said, but whether doing so becomes official policy will depend on discussions by the Centers for Disease Control and Prevention, the Food and Drug Administration, medical societies and others, which could take months."
Comment, JSJ: Of course this should be prescribed -- at least for men who need it and want it to reduce their risk of getting infected with HIV.
