Active clinical trials for "HIV Infections"

This study aims to: 1) adapt the theory-based P3 (Prepared, Protected, emPowered) app designed to improve pre-exposure prophylaxis (PrEP) adherence, retention in PrEP clinical care, and PrEP persistence among young men who have sex with men (YMSM) in the United States for YMSM in Thailand, and 2) conduct a pilot randomized controlled trial (RCT) to assess the feasibility, acceptability, and potential impact of the adapted P3-Thailand (P3-T) app.

The vast majority of new HIV infections occur in sub-Saharan Africa, where nearly 2 million people become infected with HIV/AIDS every year. Forty-five percent of these new HIV infections occur among people under 25 years old, and nearly all of them are due to unprotected sex. Ensuring the adoption of safer sexual behavior among youth is critical to keeping the new generations free of HIV. This research study aims to examine, through a large randomized controlled trial, the impact of two HIV prevention strategies among a youth population in Kenya: Voluntary Counseling and Testing for HIV (VCT), and condom distribution.

The response to primary tetanus immunization of HIV-infected children is lower than that of uninfected children. Response to tetanus toxoid (TT) booster doses in adults living with HIV who have received primary vaccination prior to infection is not known. Currently, it is recommended to have a TT booster for people living with HIV (PLHIV) every 10 years. In general population, this recall is made only at 25, 45 and 65 years, then every 10 years.

The main aim is to develop and assess an intervention to enhance initiation and adherence to PrEP among HIV negative young women of high risk (YWHR). The specific aims are (1) To conduct formative research to enhance our understanding of the dynamics of the social and sexual networks, and context of young HIV-uninfected women (aged 15-24) engaged in high risk sexual behavior in Kampala, Uganda (2) Document barriers and opportunities for PrEP uptake and adherence as well as repeat HIV testing by self test; (3) To develop and test a socially and culturally acceptable and feasible prevention intervention on uptake and adherence to PrEP and HIV self-testing for young women at high risk for HIV.

This RCT will randomly assign 40 of the CBOs to receive the Multimedia intervention and training package (Multimedia)and the other 40 to receive the original, manualized Connect intervention and training package (Traditional). The technology transfer process involves all agencies receiving four days of training and two planned technical assistance conference calls, by study investigative staff, in the first four months following training. Telephone assessments completed by up to 6 staff at each agency will measure primary outcomes, mediating, moderating and process measure variables at baseline, 6, 12 and 18 months post-technology transfer. The primary outcome of the study is adoptions of the Connect intervention. The unit of analysis is the CBO.

During the formative research phase, investigators will undertake formative studies to locate, understand, and characterize high-risk social networks of African American MSM in the community; gain community participation, involvement, and input; and undertake interviews with key informants and community members to gain information needed to pilot test study recruitment procedures, measures, and intervention content. During a 4-year main outcome trial phase, the investigators will enroll 24 separate sociocentric ("bounded") social networks composed predominantly of Black MSM. Each sociocentric network will consist of the ring of friends surrounding an initial high-risk index as well as all friends surrounding persons in this second ring and then friends surrounding a successive third snowball ring of enrollees. Each 3-ring sociocentric network is expected to consist of approximately 40 unique members (n=24 networks, each with 40 members = approximately 960 individual participants). All participants will be assessed at baseline to measure sexual practices, substance use, and other risk characteristics over the past 3 months; asked to provide biological specimens to be tested for HIV and other sexually transmitted diseases (STDs); and counseled in HIV/STD risk reduction. STDs will be treated and those with HIV will be referred for treatment. The investigators will identify the individuals in intervention condition networks with the greatest number of reciprocal interconnections and the most favorable sociometric standing in the network. These individuals--expected to constitute approximately 20% of the sociocentric network and designated as network leaders--will be recruited to attend a 9-session program that provides training and guidance in how to deliver on-going, theoretically-based, and culturally tailored risk reduction advice and counseling to other members within the same network. Six and 18 months following the intervention, all participants will be reassessed on risk behavior and STD/HIV laboratory measures as well as measures of intervention exposure, with positive STD and HIV cases respectively treated or referred to care at each assessment point. Outcome analyses will test whether there is greater reduction in high-risk sexual practices, substance use associated with risky sex, and HIV/STD incidence within social networks in the intervention condition. The primary trial endpoints are reductions in prevalence and frequency of unprotected anal intercourse with nonexclusive partners, increased condom use, and lower incidence on a composite biological measure of new HIV/STD disease during the followup period.

The proposed study seeks to continue the implementation of Connect to Protect® (C2P), a community mobilization intervention, which entails developing coalitions to plan for and bring about structural changes for purposes of reducing HIV incidence and prevalence among youth in targeted communities at five ATN sites.

The proposed study seeks to continue Connect to Protect® (C2P) community mobilization efforts that have developed coalitions that plan for and bring about structural changes for purposes of reducing HIV incidence and prevalence among youth in targeted communities at nine sites.

The investigators propose to study the impact of nucleic acid amplification testing (NAT) screening for acute Human Immunodeficiency Virus (HIV) and Hepatitis C (HCV) infections and Less-Sensitive Enzyme linked Immunoassay (LS-EIA) or 'detuned' testing Vironostika, Trinity Biotech BED, or Ortho-Clinical Diagnostic Vistros ECi for early HIV infection in conjunction with routine rapid HIV testing at HIV counseling and testing sites and venues in the San Diego county. The overarching goal of this study is to develop and implement a system to identify, notify and engage into care those individuals with recent HIV infection in order to better define the HIV and Hepatitis C Virus (HCV) epidemics in the San Diego county and to evaluate and characterize HIV transmission dynamics within the San Diego population.

The primary objective of Adolescent Impact is to develop and evaluate a developmentally targeted intervention designed to minimize secondary transmission risk behavior and enhance adherence to care and treatment. The intervention is delivered in 12 sessions (five one-to-one, 7 group) over a 3 month period of time. Intervention is delivered in addition to standard of care treatment at the participant's respective clinic. Participants are randomized to either an intervention or control arm; the control group receives standard of care treatment and control group participants are offered the Adolescent Impact intervention following the completion of the nine-month follow up. It is hypothesized that compared to control group participants, intervention group participants will evidence (1) improved or stable virologic and/or immunologic status, mediated by (a) adherence to prescribed antiretroviral medication and/or (b) adherence to HIV care appointments, and (2) reduction/minimization of secondary transmission risk behaviors to include (a) unprotected sex and/or needle sharing, and (b) sexual and drug use behaviors that increase risk for unprotected sex.
