The purpose of this study is to provide biomedical and behavioral information that is necessary for planning and starting HIV prevention trials in Lima, Peru.

The occurrence of HIV is high among men who have sex with men (MSM) in Lima, Peru, and bacterial sexually transmitted diseases (STDs) and HSV-2 (genital herpes) are very prevalent in HIV-positive and -negative MSM there. Methods to reduce both HIV and STDs are urgently needed among MSM in Peru. The information gained from this study is very important for future HIV prevention and vaccine trials that will take place in Peru.

Further study details as provided by National Institute of Allergy and Infectious Diseases (NIAID):

Estimated Enrollment: 250
Detailed Description:

HIV incidence is high among MSM in Lima, Peru, and bacterial sexually transmitted diseases (STDs) and HSV-2 are prevalent in both recently and chronically HIV-infected MSM as well as HIV-uninfected MSM. Bisexual HIV-infected MSM could be an important "bridge" transmitting HIV and other STDs to women. Interventions to reduce both HIV and STDs are urgently needed among MSM in Peru. Given these associations and the high prevalence of STDs among MSM in Lima, prevention of HIV infections is dependent partially on innovative methods to control bacterial and viral STDs among high-risk HIV-uninfected MSM. The data from this prevention preparedness study is critical for future HIV prevention and vaccine trials that will be conducted in Peru.

All MSM are counseled and tested for HIV, HSV-2, and syphilis at the screening visit. [AS PER AMENDMENT 07/23/02: The syphilis test results are provided at screening, whereas the HIV and HSV-2 test results are provided at the enrollment visit.] High-risk HIV-uninfected MSM in Lima, Peru, are enrolled. Men are interviewed about risk behaviors in the past 6 months. Trained counselors provide risk-reduction counseling according to locally accepted standards. Men are followed at 3-month intervals for 1 year to determine the incidence of and risk factors for prevalent and incident HIV and HSV-2, and to evaluate the effectiveness of retention strategies. In the baseline questionnaire, 2 additional modules address sexual networks and willingness to participate in HIV vaccine or prevention trials, including an acyclovir trial. Study data are collected and entered into a local database.
