Circumcision Not Effective in Preventing HIV Among MSM, Study Finds
[Oct 08, 2008]
Despite research showing circumcision can reduce a man's risk of HIV during heterosexual intercourse, a study published Wednesday in the Journal of the American Medical Association found that the procedure offers little protection against the virus for men who have sex with men, AFP/Yahoo! News reports. According to the study, there was minimal difference in HIV infections between those MSM who were circumcised and those who were not (AFP/Yahoo! News, 10/7).
For the study, researchers at CDC, led by Gregorio Millett, reviewed 15 previous studies on circumcision that included 53,567 MSM from Australia, Great Britain, Canada, India, the Netherlands, Peru, Taiwan and the U.S. Circumcised MSM were 14% less likely to be HIV-positive than those who were not, a rate that was not statistically significant, according to the researchers. Millett said, "You can't necessarily say with confidence that we're seeing a true effect there," adding, "Overall, we're not finding a protective effect associated with circumcision" for MSM (Dunham, Reuters, 10/7).
However, when examining studies carried out before the introduction of highly active antiretroviral therapy in 1996, the researchers found evidence that circumcision in the past had a protective effect for MSM, BBC News reports. The researchers said one explanation for the reduced effectiveness of circumcision among MSM following the introduction of HAART is that the efficacy of drugs diminished the perceived need to practice safer sex to avoid contracting HIV. In addition, the study noted that HAART might help reduce the risk of HIV transmission to a level that circumcision does not provide further benefits. The researchers also said that there may have been a smaller proportion of men in the pre-HAART trials who engaged primarily in receptive anal sex, which carries the greatest risk of HIV among MSM (BBC News, 10/7).
CDC's Peter Kilmarx, who was not involved in the study, said the agency is set to release a draft of formal recommendations on circumcision early next year. Although Millett said circumcision cannot be recommended as a strategy for HIV prevention among MSM in the U.S., he added that there are signs the procedure could protect certain MSM depending on sexual practices. For example, Millett said that studies in Australia and Peru have shown that men who engaged only in insertive anal sex and were not being penetrated by male sex partners experienced a greater level of protection from circumcision (Reuters, 10/7). However, Millett said, "Even if we find that insertive men are protected, that might be such a small proportion that we wouldn't get the effect on the overall population that we'd like. As it stands now, circumcision is unlikely to have the same kind of benefit [in the U.S.] that it's projected to have in Africa" (Lauerman, Bloomberg, 10/7).
According to the authors, more research might be needed to determine the amount of protection provided by circumcision for insertive MSM (AFP/Yahoo! News, 10/7). "These studies weren't designed to answer this question in the first place, and it's possible that they're too varied to show an effect," Millet said, adding, "The idea makes sense, but there just aren't enough data out there right now to show whether there's a benefit" (Bloomberg, 10/7). In a related editorial also published in JAMA, a team of peer reviewers from Vanderbilt University wrote that "circumcision would likely be insufficiently efficient to be universally effective in reducing HIV and will have to be combined with other prevention modalities to have a substantial and sustained prevention effect" (AFP/Yahoo! News, 10/7).

Vietnam Launches Nationwide HIV/AIDS Initiative
[Oct 08, 2008]
Vietnam on Monday announced the launch of a nationwide initiative, called "Every Citizen is Involved in HIV/AIDS Control and Prevention Activities at Community Level," to curb the spread of the disease in the country, the Vietnam News Agency reports. The program will be implemented by the Ministry of Health, the Ministry of Culture, Sports and Tourism and the Vietnamese Fatherland Front Control Committee and will run through 2012. Health Minister Nguyen Quoc Trieu said the initiative's goals are to raise awareness of prevention and control methods. He added that the program aims to encourage and create opportunities for families with HIV-positive members, commercial sex workers and injection drug users to become involved in prevention and control activities. Nguyen Thanh Long, head of the Department of HIV/AIDS Control at the health ministry, said that many people in remote, rural areas of Vietnam are unaware of HIV prevention methods (Vietnam News Agency, 10/6).

UNESCO Program To Help Teachers in Zimbabwe Access Drugs, Other Services
[Oct 08, 2008]
UNESCO plans to launch a network of HIV-positive teachers in Zimbabwe to help the group access no-cost antiretroviral drugs and other services, Zimbabwe's The Herald reports. Bekezela Mapanda -- UNESCO program assistant for education and HIV/AIDS -- said that the network aims to provide assistance to teachers, who often are poorly paid, to manage the rising price of drugs and other services. "We all know their salaries are very poor," Mapanda said, adding, "They cannot afford all the procedures needed before one is put on antiretroviral treatment; worse still, the drugs are required monthly." Teachers in Zimbabwe earn an average of 12,000 Zimbabwean dollars, or about $78, monthly, and antiretrovirals cost an average of $225,000 Zimbabwean dollars -- or about $1,460 -- monthly. The cost of antiretrovirals can fluctuate daily, The Herald reports.
According to Mapanda, teachers have "dominated cross-border trade business to raise extra income, causing them to engage in risky behavior, exposing them to risks of contracting HIV." She added that the network will allow teachers to access no-cost antiretrovirals, take part in national HIV/AIDS programs, and review workplace initiatives and policies. The UNESCO program follows recent comments from HIV-positive teachers in the country about their inability to access antiretrovirals from the government's program, as well as the high costs of the drugs at private pharmacies. According to some HIV-positive teachers who attended World Teachers' Day events in the capital of Harare last week, Zimbabwe's National AIDS Council should consider them when allocating budgetary assistance as it does for the armed forces. "I am lucky to be accessing free drugs, but my fear is that my health is deteriorating because of lack of a balanced diet and overworking catering for my family," teacher and HIV/AIDS advocate Joana Kasirori said. She also called on teachers to undergo voluntary HIV/AIDS testing and counseling and develop a network of HIV-positive teachers. Zimbabwe Teachers' Association President Tendai Chikowore said that teachers affected by HIV/AIDS feel most of the effects of inflation and other economic issues. "The situation is worse for our colleagues living with HIV and AIDS owing to prohibitive medical costs versus the teachers' meager salaries," she said (The Herald, 10/7).

HIV/AIDS Workshop in Ghana Addresses Women's Issues, Media's Role in Fight Against Disease
[Oct 08, 2008]
At a recent workshop held by Women, Media and Change, Afua Ansre, national coordinator of the United Nations Development Fund for Women in Ghana, said that obstacles to HIV/AIDS prevention -- including a lack of access to information, education and health care -- are compounded by a deficit of sex-specific data on monitoring systems, Ghana's Public Agenda reports. Ansre also said that women should be provided with education about the disease, particularly for the prevention of mother-to-child transmission. She added that governments, nongovernmental organizations and individuals must work together "to implement structured programs to prevent the spread" of HIV/AIDS.
