Active clinical trials for "Immunologic Deficiency Syndromes"

People infected with HIV are now living longer lives because of the use of highly active antiretroviral therapy (HAART). However, HAART medications have been shown to increase the risk of cardiovascular disease and metabolic dysfunction in adults. More research is needed on the effect of HAART in children. The purpose of this study is to assess cardiovascular risk factors in children infected with HIV who receive HAART medications and to determine the effectiveness of an exercise program on cardiovascular outcomes in these children.

The purpose of this study is to determine whether dapivirine gel 4789 is safe for daily use by healthy women in South Africa.

To determine whether a regimen of single dose nevirapine combined with either 4 or 7 days of Combivir®, compared to a regimen of single dose nevirapine, for the prevention of mother to child transmission can reduce the rate of development of drug resistant mutations of HIV-1, in HIV-1 infected pregnant women, who have not received antiretroviral therapy previously.

This two-arm cluster randomized trial tested a gender-focused comprehensive HIV testing and counselling (HTC) program, the Young Women's Health CoOp (YWHC) with a standard HTC program and targeted female adolescents (aged 16-19) who use substances and have dropped out of school. To evaluate the process, the study examined the feasibility of using peer role models as recruiters and co-facilitators of the intervention and monitored fidelity to the intervention. Efficacy of the intervention on behavioral and biological outcomes, and on linkages to health services, through follow-up visits conducted 6- and 12-months post-enrollment was also assessed.

This study aims to evaluate the efficacy of an intervention designed to reduce STI/HIV incidence by increasing the number of adolescent mothers who re-enroll and remain in school. The objective of the intervention is to have older mentor mothers, who themselves were pregnant adolescents, to mentor younger adolescent mothers. Mentor mothers will provide ongoing psychosocial support, help navigate re-admission to school, and help facilitate access to an existing State-sponsored cash transfer, the child support grant (CSG), in the early postpartum period. Our combination social protection program will enhance resilience of young adolescent mothers to facilitate their return to school and thereby reduce HIV risk. The investigators will evaluate the efficacy of the intervention using a pre-test post-test randomized controlled trial design. Participants in the intervention will receive the Mentoring Adolescent Mothers At School (MAMAS) intervention and standard postpartum care. Those in the control arm will receive standard postpartum care. Additionally, for those participants randomized to the intervention arm, mentor mothers will use participatory visual methods (e.g., photovoice, cell-films, drawings) as part of the intervention itself. Last, among those participants randomized to the intervention arm and who return for their 9-month assessment, the investigators will conduct 20 in-depth interviews to understand the process of resilience development from their perspective. Primary outcomes: School outcomes (initial outcomes) HYP 1.1: Program participation will increase school enrollment HYP 1.2: Program participation will increase school engagement HIV risk outcomes (intermediate outcomes) HYP 2.1: Program participation will reduce number of sexual partners HYP 2.2: Program participation will reduce inconsistent condom use HYP 2.3: Program participation will reduce intimate partner violence HYP 2.4: Program participation will decrease HIV/STI infection HYP 2.5 (for HIV+): Program participation will increase retention in care Secondary outcomes: HYP 5: Program participation will increase peer support HYP 6: Program participation will increase familial support HYP 7: Program participation will increase school re-admission HYP 8: Program participation will increase application to the child support grant HYP 9: Program participation will increase receipt of the child support grant

The aim of the study is to evaluate the safety and immunogenicity of the Dengue vaccine in a population of special interest, such as HIV-positive adults previously exposed to dengue. Primary Objective: To describe the safety of each injection of CYD dengue vaccine in HIV-positive adults previously exposed to dengue. Secondary Objectives: To describe the humoral immune response to each dengue serotype at baseline and after each injection of CYD dengue vaccine in HIV-positive adults previously exposed to dengue. To detect the CYD dengue vaccinal viremia post-Inj 1 in HIV-positive adults previously exposed to dengue. To describe changes in CD4 count and HIV RNA viral load after each injection of CYD dengue vaccine in HIV-positive adults previously exposed to dengue. Observational Objective: To describe the FV (YF, Dengue, Zika) serological status in the study population at baseline.

The purpose of this study is to determine whether dapivirine gel 4759 is safe for daily use by healthy women in Kenya, Malawi, Rwanda, South Africa and Tanzania.

The purpose of this study is to measure the pharmacokinetics, efficacy and safety of Immune Globulin Intravenous (Human) [IGIV], 5% Solution Omr-IgG-am™ in patients with primary immunodeficiency diseases.

African American men have by far the highest rates of HIV in the US, but there are few randomized controlled trials (RCTs) of interventions to dissuade heterosexually active African American men from engaging sexual risk behavior. This research seeks to address this gap in the behavioral intervention literature. That self-initiated behavior change, as well as intervention-induced behavior change, is often short-lived, eroding over time, is widely known; accordingly, this research also seeks to test a strategy to sustain intervention efficacy. In a RCT, African American men 18 to 45 years reporting recent unprotected intercourse with a woman will be randomized to the Steering Together in a New Direction (STAND) HIV Risk Reduction Intervention or a No-Intervention Control Condition. To test a strategy to sustain intervention effects, the men also will be randomized to receive or not receive individually tailored text messages. The theoretical basis of the interventions is social cognitive theory and the reasoned action approach, which is an extension of the theory of planned behavior and the theory of reasoned action. Men will complete self-report measures via audio computer-assisted self-interviewing at baseline and immediately post and 6 and 12 months post-intervention. The trial will test whether the STAND HIV Risk Reduction Intervention as compared with the No-Intervention Control Condition, increases consistent condom use, the primary outcome. Secondary outcomes include unprotected intercourse, multiple sexual partners, insertive anal intercourse, and proportion condom-protected intercourse. The trial will also test whether STAND's efficacy is greater among men in the Text Messaging Intervention compared with men not receiving text messages. This will provide information on the utility of a low-cost strategy to extend an intervention's efficacy. Finally, the study will test for mediation of intervention effects: the hypothesis that STAND affects outcome expectancies and self-efficacy, which, in turn, affect consistent condom use.

To assess the safety of dapivirine (25 mg) administered via a silicone vaginal ring in HIV-uninfected adolescent females, when inserted once every 4 weeks during 24-week of study product use.
