Led by study chair Myron Cohen, M.D., director of the Institute for Global Health and Infectious Diseases at the University of North Carolina at Chapel Hill, HPTN 052 began in 2005 and enrolled 1,763 heterosexual couples in Botswana, Brazil, India, Kenya, Malawi, South Africa, Thailand, the United States and Zimbabwe. Each couple included one partner with HIV infection. The investigators randomly assigned each couple to either one of two study groups. In the first group, the HIV-infected partner immediately began taking a combination of three antiretroviral drugs. The participants infected with HIV were extensively counseled on the need to consistently take the medications as directed. Outstanding compliance resulted in the nearly complete suppression of HIV in the blood (viral load) of the treated study participants in group one.
In the second group (the deferred group), the HIV-infected partners began antiretroviral therapy when their CD4+ T-cell levels—a key measure of immune system health—fell below 250 cells per cubic millimeter or an AIDS-related event occurred. The HIV-infected participants also were counseled on the need to strictly adhere to the treatment regimen.
It was found that those taking the medication while their immune system was still highly healthy were 96% less likely to transmit HIV to their partners. This result was so stupendous that, even though the trial is still ongoing, an early public release of the findings was ordered. It is important that people know how to best combat transmission. That spread of information is what is needed to prevent the spread of infection:
“On its own, treatment as prevention is not going to solve the global HIV/AIDS problem,” said Dr. Fauci. “Yet when used in combination with other HIV prevention methods—such as knowing one’s HIV status through routine testing, proper and consistent condom use, behavioral modification, needle and syringe exchange programs for injection drug users, voluntary, medically supervised adult male circumcision, preventing mother-to-child transmission, and, under some circumstances, antiretroviral use among HIV-negative individuals—we now have a remarkable collection of public health tools that can make a significant impact on the HIV/AIDS pandemic.”
“Scale-up of these proven prevention methods combined with continued research toward a preventive HIV vaccine and female-controlled HIV prevention tools places us on a path to achieving something previously unimaginable: an AIDS-free generation,” Dr. Fauci added.
I added the emphasis to the above excerpt because I am reminded of the utter irresponsibility displayed by PZ Myers on this issue in the past. While I still very much like what the guy has to say on many subjects, he was dead wrong to dismiss any one of the listed tools. In this case, he specifically dismissed the notion that there is any evidence whatsoever that circumcision has any impact on HIV infection rates. As I’ve documented elsewhere, he is absolutely wrong on the facts. That evidence does exist and it is important that it is known. That is why Dr. Fauci noted it amongst all the other ways we must use to combat this disease. HIV/AIDS is one of the most serious epidemics facing the developing world today; no one should be proud to exacerbate the problem, especially when the motivation is ideological in nature – we’re talking about god damned human lives here.
