Filter by:Rifampin (RIF) is used for the treatment of tuberculosis (TB), an infectious disease that affects many people with HIV. RIF was shown to lower concentrations and decrease the effectiveness of some anti-HIV drugs, including the HIV protease inhibitor (PI) atazanavir (ATV) boosted with ritonavir (RTV). The purpose of this study is to determine the interactions between RTV-boosted ATV and evaluate the safety and tolerability of giving these drugs together in HIV uninfected adults.
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.
The purpose of this study is to collect blood samples from HIV infected individuals for use in future genetic studies.
Oral contraceptives (OCs) are not a good option for some HIV infected women because of the potential for drug interactions between OCs and anti-HIV drugs; additionally, OCs may increase the risk of transmitting HIV to sexual partners. Levonorgestrel is commonly prescribed as part of a combination OC. An intrauterine device (IUD) is a device inserted in a woman's uterus to prevent pregnancy. The purpose of this study is to determine the effect of a levonorgestrel-releasing IUD on the amount of HIV present in an HIV infected woman's cervix after 4 weeks of IUD use. Study hypothesis: There will be no increase in genital tract HIV RNA and DNA after placement of the levonorgestrel IUD.
The purpose of this study is to estimate the amount of HIV and tuberculosis (TB) infection in individuals 15 years and older in the Masiphumelele township of Cape Town, South Africa. Data collected in this study will be used to predict the effect of introducing anti-HIV therapy in this community.
This study will test the safety and efficacy of an investigational Human Immunodeficiency Virus (HIV) vaccine. Efficacy will be measured by either prevention of HIV infection or control of HIV viral load in subjects who become HIV infected. On September 18, 2007 the Protocol V520-023 DSMB (Data & Safety Monitoring Board) reviewed data from a planned interim analysis. These data demonstrated that the investigational vaccine candidate was not effective, and all vaccinations in the study were halted. Participants were encouraged to continue to come to the clinic for scheduled visits and ongoing risk reduction counseling since the vaccine was not effective.
This study was designed to evaluate and compare safety, tolerability of subjects who successfully suppress HIV-1 on their first PI regimen to those who switch to fosamprenavir. This is a 48-week study, where subjects who were assigned to be in their original PI-group have the option of switching to fosamprenavir on week 24. Prior to being assigned their treatment group, subjects had to be suppressed for at least three months. All subjects also take a background regimen of two nucleoside/nucleotide reverse transcriptase inhibitors.
This study was designed to evaluate if subjects who took 600 mg of abacavir and 300 mg of lamivudine once-daily as a single tablet were just as likely to have adverse events compared to subjects who took 300 mg of abacavir and 150 mg of lamivudine administered as separate tablets twice-daily.
The purpose of this study was to examine the needs, concerns, stigmas, and social networks of HIV infected former plasma donors (FPDs) and their relatives in Fuyang, Anhui Province, China. Interviews and focus groups were used to collect data in preparation for a future, larger behavioral study for HIV infected individuals in China.
Tuberculosis (TB), a bacterial infection common in HIV infected people, is a major problem in developing countries. The purpose of this study is to test the effectiveness of a combined treatment strategy using directly observed therapy (DOT) for HIV infected patients with TB. Participants will be recruited from resource-poor communities in Durban, South Africa.
