There are about 193 clinical studies being (or have been) conducted in Zimbabwe. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to determine how often dementia and other neurological problems occur in people with HIV. Participants of ACTG A5175 will enroll in this study.
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are commonly included in anti-HIV drug regimens. However, HIV infected women who have previously taken the single dose NNRTI nevirapine (SD NVP) for the prevention of mother-to-child transmission (MTCT) of HIV may not respond as well to NNRTIs as women who have never taken NVP. Another class of anti-HIV drugs, protease inhibitors (PIs), may be more effective for women who have previously taken NNRTIs. This study will compare the effectiveness of NNRTI- and PI-based regimens in women who have taken NVP for prevention of MTCT of HIV. This study will also compare regimens including an NNRTI with regimens including a PI in women who have never taken NVP.
This is a long-term follow-up study of people who are identified during acute or recent HIV infection and are being followed at clinical research sites associated with the Acute HIV Infection and Early Disease Research Program (AIEDRP).
This study compared 3 different three-drug combinations in HIV infected individuals starting their first HIV treatment regimens. Participants were recruited from resource-limited areas in Africa, Asia, South America, Haiti, and also from the United States. The study hypothesis was each of the once daily combinations (PI based, or NNRTI based) would not have inferior efficacy compared to the twice daily NNRTI based combination.
This study will determine whether anti-HIV drugs can prevent the sexual transmission of HIV among couples in which one partner is HIV infected and the other is not.
The majority of HIV infected people worldwide became infected with the virus through heterosexual contact. BufferGel and PRO 2000 Gel are vaginal gels designed to prevent women from becoming infected with HIV during sexual intercourse with an HIV infected partner. This study will test the safety and effectiveness of these gels.
The many benefits of breastfeeding are well documented. However, because of the risk of mother-to-child transmission (MTCT) of HIV from an HIV infected mother to her infant, there is considerable concern over the practice, especially in developing countries. The purpose of this study is to determine the safety and effectiveness of the anti-HIV drug nevirapine (NVP) in preventing MTCT of HIV in breastfeeding infants born to HIV infected women in South Africa, Tanzania, Uganda, and Zimbabwe.
