简要总结
This randomized controlled trial conducted in Rakai District, Uganda, has enrolled 997 HIV positive men and 500 men who declined to learn HIV results (regardless of HIV status). The hypotheses are that male circumcision will be acceptable to and safe in both groups and will reduce the rates of STD acquisition in both groups and of HIV acquisition in HIV-negative men.
Enrollment was ended on Dec 12, 2006, following an interim Data Monitoring and Safety Board (DSMB) review of a closed report. At that time the DSMB determined that futility with respect to the female HIV outcome. There was an non-significantly higher rate of HIV acquisition in women partners of HIV+ men in couples who had resumed sex prior to certified post-surgical wound healing. The data indicated significant reductions (~50%) in GUD symptoms among circumcised HIV+ men. The DSMB recommended: 1) that men and women should continue to be followed in complete two year follow up on all, 2) that circumcision for remaining HIV+ intervention arm men and for control arm men who had completed their 2 year follow should continue, contingent on a) revision of the study protocol to add additional post-surgical visits to assess wound healing, b) protocol revision to further strengthen education for both male and female partners on the need to postpone sex until certified wound healing, and c) approval of the revised protocol by the IRBs in both the US and Uganda. 3) An additional follow up visit for women be instituted at 18 months after enrollment. Protocol revision and IRB approvals have been finalized in June, 2007.
The study has also enrolled and is following 3,700 women sexual partners of men enrolled in this study and in a complementary National Institutes of Health (NIH) funded study (U1 AI51171 which is separately registered). The hypotheses are that male circumcision will be acceptable to and safe in women partners, and will reduce the women's acquisition of HIV and STDs such as herpes simplex virus-2 (HSV-2) and human papillomavirus (HPV).
详细描述
STUDY DESCRIPTION:
The study is being carried out by the Rakai Health Sciences Program, a research collaboration between the Uganda Virus Research Institute/Uganda Ministry of Health, Johns Hopkins Bloomberg School of Public Health and researchers from Makerere University, Kampala, Uganda.
- The study, being conducted in Rakai District, Uganda, has enrolled 997 HIV+ and following a detailed informed consent process, randomizing them to receive either immediate (within several days or weeks) or delayed (two years) circumcision. The goals are to assess the safety and acceptability of male circumcision among HIV+ men, and to assess potential effects of male circumcision on the acquisition of STDs such as HSV-2. Hypotheses are that male circumcision will be acceptable to and safe in HIV+ men, will reduce the rate of acquisition of STDs, and will reduce the frequency of STD symptoms, such as genital ulceration.
- The study has also enrolled 500 men who, regardless of their HIV status, decline to receive their HIV results, despite encouragement to do so. Hypotheses are that circumcision will be acceptable and safe in men who decline their HIV results, and will reduce the rate of acquisition of HIV and STDs, and the frequency of STD symptoms such as genital ulcers.
- The study has enrolled 3,700 female partners of the men in groups 1 and 2 above, as well as of 5,000 HIV-negative men enrolled in a complementary NIH-funded study of male circumcision for HIV prevention (U1 AI51171 which is being separately registered). Following informed consent, the women partners are being followed annually to assess the acceptability and safety of male circumcision in female partners, and potential effects of male circumcision on HIV and STD acquisition. The hypotheses are that male circumcision will be acceptable to and safe in women partners, and will reduce the acquisition of HIV and STDs such as HSV-2 and HPV (human papilloma virus which causes cervical cancer.)
- Finally, the study is also following ~3,000 men and women in the ~50 communities where the circumcision trials are taking place, in order to assess community attitudes towards and knowledge of male circumcision, and to assess whether other preventive behaviors (abstinence, monogamy, numbers of partners, condom use, etc...) change in the community once circumcision becomes available. The hypothesis is that male circumcision will be acceptable in the community and will not result in behavioral disinhibition (increased rates of high risk behaviors).
The Gates-funded study being registered here is complementary to a separate NIH-funded trial of male circumcision in HIV-negative men who accept their HIV results, being carried out by the Rakai Health Sciences Program study team. The latter study, which is enrolling 5000 HIV-negative men, is designed to answer whether male circumcision is acceptable and safe in HIV-neg men, and whether the procedure reduces the acquisition of HIV and STDs.
The complementary Gates-funded trial is designed to answer the following additional questions:
