Active clinical trials for "HIV Infections"

The Active Search for Pediatric HIV/AIDS (ASPA) aims at assessing the acceptability, feasibility and effectiveness of the targeted provider-initiated-testing and counseling (tPITC) in comparison with the blanket provider-initiated-testing and counseling (bPITC) among children and adolescents in Cameroon. The new knowledge generated will inform programming of more suitable strategies to identify HIV-infected children and adolescents and this will contribute to reducing the current global gap in HIV treatment among this subpopulation group.

This Mentored Patient-Oriented Research Career Development Award - (K23) seeks to provide the advanced knowledge, skills, and experience for the candidate's career transition to an independent nurse scientist. Her long term goal is to become a leading nurse scientist in designing, implementing, and evaluating technology supported behavioral interventions targeted for improved disease self-management (i.e. medication adherence, retention in care) among human immunodeficiency virus (HIV)-infected, ethnic minority adolescents and young adults. With an extensive background in pediatric HIV nursing and completed NIH funded pre and post-doctoral interdisciplinary research traineeships, the candidate has begun to develop the knowledge-base and skills necessary for this goal. This award details a 3-year scope of mentored career development through which she will gain the foundation for future research endeavors. Specifically, the goals of this proposal are to: 1) conduct a novel research project under the mentorship of an interdisciplinary team of expert researchers; 2) acquire expertise in health informatics for implementation of technology supported behavioral interventions, health disparities, and advanced qualitative and mixed methods design and analysis through firsthand experience, didactic interactions with mentors, and graduate level coursework; 3) build a network of colleagues and collaborators within New York University and elsewhere through this research and participation at national and international meetings; and 4) prepare and submit a federal research grant (R-21) based upon the skills and findings from this award period. The specific research project through which she will accomplish these goals is a proof of concept study, Adherence Connection for Counseling, Education, and Support (ACCESS), and addresses the challenge of adherence to antiretroviral treatment among HIV-infected adolescents and young adults. A mixed method design is proposed and the specific aims are to: 1) Characterize the feasibility and acceptability of a peer led, mHealth cognitive behavioral intervention delivered via remote videoconferencing using smartphones; 2) Obtain initial estimates of the biobehavioral impact of ACCESS on HIV virologic outcomes and self-reported ART adherence, beliefs and knowledge about antiretroviral treatment, adherence self-efficacy, and healthcare utilization (retention in HIV care). In summary, the ACCESS adherence intervention is consistent with the National Institute of Nursing Research (NINR) call for the development of novel interventions to deliver personalized care and real-time health information for patients.

Sanu Gundo ANRS 12392 is a non-randomized and non-comparative intervention trial in Mali. The main objective of the project is to study the feasibility of the community-based HIV care in the context of the artisanal gold mining zones and to evaluate its contribution to the linkage-to-care of PLWHIV with the health system and their retention in care, as well as its effect on their health status.

The primary purpose of the study is to better define the relative contributions of AIDSVAX® B/E alone, ALVAC-HIV alone, or ALVAC-HIV plus AIDSVAX® B/E combination to the observed immune profile in the weeks and months after receiving the original prime and boost vaccine regimen from study protocol RV 144, and their booster effects in both the systemic and mucosal compartments. In addition, this study will provide more intensive and comprehensive characterization of the innate, cell-mediated and humoral immune responses than possible within the RV 144 study.

Objectives: Primary: Safety and immunogenicity of MVA.HIVA vaccine in 20-week-old healthy Kenyan infants born to HIV-1-infected mothers. Secondary: HIV-1 immunogenicity comparison between MVA.HIVA and age-matched unvaccinated control arms in each cohort (breastfeeding or formula feeding) HIV-1 immunogenicity comparison between breastfeeding and formula feeding infants receiving MVA.HIVA HIV-1 immunogenicity comparison between breastfeeding and formula feeding infants in the age-matched unvaccinated control group Comparison of responses to certain Kenyan Extended Programme on Immunization (KEPI) vaccines (OPV, DTP, HBV, and HiB) between MVA.HIVA versus age-matched unvaccinated controls in each cohort, between breast versus formula feeding infants in the age-matched unvaccinated control group, and between breast versus formula infants receiving MVA.HIVA Comparison of immune activation and phenotypic profile of lymphocytes between breast and formula feeding infants in each cohort (MVA.HIVA and age-matched unvaccinated control) Build capacity for Infant HIV-1 Vaccine Clinical Trials Centre in Nairobi, Kenya.

2. Objectives To determine the vitamin D status of African-American HIV patients who are HIV-treatment naïve. To compare the effects of an efavirenz-containing regimen to a protease inhibitor regimen on 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3 levels. To compare the effect on bone density of a tenofovir- and efavirenz-containing regimen to a regimen that does not contain these drugs. To compare the efficacy of an alternative regimen (raltegravir, darunavir, ritonavir) to a standard once-daily regimen (tenofovir-emtricitabine-efavirenz). Hypothesis The investigators hypothesize that patients receiving efavirenz will be more likely to have lower 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3levels based on the fact that efavirenz is an inducer of CYP3A4 and CYP24 enzymes that degrade 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3, respectively, to inactive metabolites. The investigators speculate that patients on a tenofovir-containing regimen will be more likely to have progression of bone density loss compared to those in the non-tenofovir-containing regimen.

The investigators will evaluate the effects of an endurance exercise program on the physical performance, the well being, and indicators of metabolic function in patients with an HIV infection.

The female condom offers women a potentially important option for HIV prevention. This study will develop and evaluate a health education program to increase female condom use among ethnically diverse women.

Many older adults in rural South Africa still lack knowledge of their HIV status despite a high probability of infection. Older adults tend to test less for HIV because most HIV testing and prevention programs have been targeted at younger age groups. Other reasons for failure to test for HIV include frailty and lack of financial resources to travel to HIV testing centers. Home-based testing is a powerful approach to bring HIV testing services -- and HIV status knowledge -- to older adults. In real-life health systems, community health workers, such as the South African community care givers, could potentially provide home-based HIV testing on a routine basis. In this study, the investigators are trying to establish the best 'form' for the 'function' home-based HIV testing. Specifically, the investigators aim to Establish the comparative effectiveness of three home-based HIV testing options among older adults in rural South Africa Identify spill-over effects of the different home-based HIV testing options to other adults in the households and communities of the older adults receiving the testing options Determine the comparative cost-effectiveness of the three home-based HIV testing options among older adults.

Breastfeeding remains the optimal mode of feeding for infants younger than six months. Exclusive Breast Feeding (EBF) among HIV-infected mothers has been shown to be associated with a sustained and significant reduction in HIV transmission and has the potential to reduce infant and under-five mortality. Given the considerable authority among men as decision makers in sub-Saharan African, we may be witnessing a missed opportunity to engage men in the education, awareness, and decision-making for EBF. Understanding the role and impact of male partners on this decision-making process require further examination to inform the development of effective and sustainable evidence-based interventions to support the initiation and sustainment of EBF.
