Active clinical trials for "HIV Infections"

The purpose of this study is to find the best strength of chlorhexidine (a solution that kills germs), for washing the mother's vagina during labor and the newborn baby, that may reduce the chance of HIV being passed from an HIV-positive mother to the baby. When used as a wash on the vagina during labor, and on a newborn shortly after birth, a higher dose of chlorhexidine is more likely to reduce the rate of HIV-1 transmission from mother to baby. Laboratory tests suggest that a higher dose of chlorhexidine will be more effective in killing HIV.

The purpose of this program evaluation is to determine whether the Preventing AIDS Through Live Movement and Sound (PALMS) group-level intervention is effective in reducing HIV sex risk behaviors and increasing HIV testing of high-risk, incarcerated or adjudicated youth. The intent of this program is to support the evaluation of an existing intervention and provide feedback to the implementing organization for improved program effectiveness, not to conduct research.

Genital herpes (HSV-2) is the most common cause of genital sores worldwide, and the presence of genital sores is a significant risk factor for becoming infected with HIV. This study will test the effectiveness of twice-daily dosing of acyclovir, a commonly prescribed anti-herpes drug, in preventing HIV infection in HSV-2 infected women who sleep with men (WSM) and men who sleep with men (MSM). Study hypothesis: Given that genital herpes is a significant risk factor to HIV acquisition, twice-daily HSV-2 suppressive therapy - 400 mg of acyclovir - will prevent HIV infection among high risk, HSV-2 seropositive WSM and MSM.

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 evaluate the safety of and immune response to two HIV vaccine formulations, rMVA-HIV and rFPV-HIV, alone and in combination, in HIV uninfected adults.

People recently infected with HIV who are treated with anti-HIV medications may develop strong immune system responses to HIV and may be able to control the virus without continuing to take these medications. The purpose of this study is to see if giving anti-HIV medications to people soon after they have been infected with HIV can help them control HIV. The study will also see if the immune system can control the amount of HIV virus in the blood (viral load) even after a person has stopped taking the medications. The study will evaluate three different schedules of stopping and starting anti-HIV medications to see which schedule is best able to boost a patient's immune system to control HIV viral load. Hypothesis: Combination therapy started in primary HIV infection, in conjunction with structured treatment interruptions, will result in greater control of viremia off treatment than induction therapy alone.

Voluntary HIV counseling and testing (VCT) and anti-HIV drugs for pregnant women and their newborns decrease rates of mother-to-child transmission (MTCT) of HIV. This study will determine the acceptability of HIV counseling and rapid testing prior to delivery and will compare the usefulness of VCT prior to birth versus after birth in preventing MTCT of HIV in pregnant women in Cape Town, South Africa. This study will also determine the acceptability and effectiveness of giving anti-HIV medications to prevent MTCT of HIV.

This study will test the safety and immune response to an experimental HIV vaccine, LIPO-5, in healthy volunteers. LIPO-5 contains 5 lipopeptides from gag, nef and pol corresponding to more than 50 epitopes. LIPO-5 has been shown to be immunogenic and well tolerated in a first phase I trial in non-HIV infected volunteers. Lower doses of each peptide could have a similar immunogenicity.

This Phase 2 study involving tenofovir disoproxil fumarate (TDF) will assess the extended safety of TDF 300 mg per day among young women who are not HIV-infected.

The specific objective of this study are to examine whether or not a treatment aimed at emotional disclosure may have beneficial psychological, health and immune effects for HIV infected individuals. The goal of the current study is to test the efficacy of emotional disclosure through writing in patients with HIV infection. We will compare emotional disclosure through writing about traumatic experiences (experimental intervention) to a control intervention (writing about emotionally neutral topics). [Note that HIV RNA viral load, CD4 T cells, urinary cortisol, health related dysfunction, psychological distress, and medication adherence are the 6 primary outcome variables.
