The Brooklyn Community United (BCU) study is a supplement to the main research study titled "Peer Driven Intervention to Seek, Test, & Treat Heterosexuals at High Risk for HIV." The main study's field name is Brooklyn Community Action Project (BCAP) (R01DA032083, R#: 11-01257). The main study is testing two approaches to seeking out undiagnosed HIV infection (Venue-based Sampling (VBS) and Confidential Two-Session Testing with Navigation (CTTN-RDS)). HIV prevalence rates in two previous heterosexual cycles of NHBS in the local area are: 7% in HET1 and 12.3% in HET2. The main study, BCAP, found lower prevalence rates of 3.45%, 35.14% of which were newly diagnosed in the RDS-CTTN sample and 1.89% newly diagnosed with HIV in the VBS sample. The primary aim of the Brooklyn Community United (BCU) study is to seek out individuals with undiagnosed HIV using a streamlined RDS-CTTN approach, and anonymous HIV Testing in Central Brooklyn. The supplement study hypotheses are: (H1): Compared with VBS and RDS-CTTN, and controlling for potential differences on key socio-demographic characteristics across the samples, RDS-ASTN participants will have less HIV testing experience. (H2) Controlling for potential differences on key socio-demographic characteristics across the samples, RDS-ASTN will yield higher rates previously undiagnosed HIV compared with VBS and RDS-CTTN. (H3): Most participants (> 70%) found to be HIV-infected in the RDS-ASTN intervention will engage in the Treat and Retain intervention phase. (H4): Most participants in the Treat and Retain phase of the RDS-ASTN intervention (> 70%), all of whom will be HIV infected, will be linked to care within 3 months.
With increasing access to antiretroviral therapy (ART) in South Africa, HIV has transitioned from a terminal illness to a long-term condition. It is likely to be accompanied by higher levels of disability and other chronic non-communicable diseases, resulting from the HIV itself, as well as adverse effects of medication. This requires an expansion of the purview of HIV care beyond direct HIV clinical care to also include a more comprehensive and integrated package of treatment and care for physical and mental conditions and their consequences. COBALT is a pragmatic cluster randomized controlled trial (RCT) in public sector primary care clinics in the North West Province of SA. It will assess mental health and HIV outcomes for depressed adults receiving ART by measuring the real-world effectiveness of a facility-based stepped care intervention combining depression case detection by non-physician clinicians with group counselling intervention delivered by lay-health workers.
The investigators are conducting a 3-arm randomized trial comparing the effects of unidirectional SMS (ie: "push" messaging to participant) vs. bidirectional SMS dialogue between participant and provider vs. control (no SMS) among HIV-infected Kenyan mothers in Kenyan PMTCT-ART for outcomes of ART adherence and retention in care.
The primary objective of the proposed phase I trial is to evaluate the safety and tolerability of DNA-HIV-PT123 and AIDSVAX®B/E combination regimen. Though both DNA-HIV-PT123 and AIDSVAX®B/E and the combination of the two vaccines have been evaluated in humans and have shown to be safe and well tolerated, this is the first time the combination regimen is being evaluated in HIV-1 uninfected African populations with and without S. mansoni. The secondary objective of the trial is to evaluate the effect of S. mansoni infection on the immunogenicity of the combination of DNA-HIV-PT123 and AIDSVAX® B/E vaccine regimen. Successful vaccination against most viruses requires efficient Th1 response. There is evidence that helminth infections skew the host immune system of human and animals to T-helper type 2 (Th2) and induce immunosuppression. Therefore, there is a potential that helminth infected populations may not generate the desired immune responses to vaccines designed to drive Th1-type and cytotoxic T-cell responses. Furthermore, the influence of helminth infections on the development of protective antibody responses remains unclear. Limited data in animal models suggests that worm infections reduced efficacy of vaccines. The proposed vaccine trial will generate safety, tolerability and immunogenicity data of a vaccination regimen with simultaneous administration of a candidate HIV DNA vaccine (DNA-HIV-PT123) and a gp120 protein vaccine (AIDSVAX®B/E). This will be the first HIV vaccine trial to prospectively evaluate the impact of the S. mansoni infection on safety and immune responses to HIV vaccines.
The purpose of the study is to evaluate the safety, acceptability, and PK/PD profile of maraviroc gel following rectal and vaginal administration. The study also includes oral exposure to maraviroc.
Consistent treatment with anti-retroviral therapy (ART) suppresses viral load (VL), prolonging life and improving quality of life for HIV+ persons. Suppressing VL benefits communities by reducing transmission to others. Mere availability of ART and care, however, is insufficient; the benefits of ART depend upon HIV+ persons' continuous visits to the health care provider, regular monitoring and regular delivery of medications, - known as retention in HIV care. In spite of national efforts, up to a quarter of HIV+ persons, especially low-income minorities are out of care. Innovative interventions are therefore urgently needed to maximize engagement and retention in HIV care, self-reported adherence, as well as HIV-1 RNA viral load suppression. In pursuit of these aims, the proposed study will assess outcomes of the following interventions in comparison to usual care: 1) contingency management (CM) only; 2) peer navigation (PN) only; and 3) a combined approach that integrates both CM and PN (CA) which the investigators hypothesize to be most effective in improving HIV clinical outcomes.
This randomized clinical trial is testing if telephone-administered interpersonal psychotherapy (IPT) can reduce depression in rural persons living with HIV/AIDS.
The primary objective is to compare & evaluate between the treatment groups the changes in decline/reduction of HIV viral load & increase changes in WBC white blood cell counts in the adult Remune dose vs the low dose Remune placebo groups. Additional objectives include changes in CD4+ & CD8+ T cell counts along with increased HIV immunity.
Clinical social workers, doctors, outreach workers, and all other staff providing direct care to vulnerable populations face multiple challenges in obtaining and maintaining training and implementing evidence based practices in diverse community settings. Motivational Interviewing is a well-established evidence based practice that is challenging to implement across programs and agencies because it requires that skills gained from training be reinforced as a service provider employs the practice. This study builds on findings from a Phase I study. With funding from a Phase I Small Business Innovation Research grant from the National Institute of Health, the Center for Social Innovation developed the Motivational Interviewing Simulator: An Experiential Online Training Tool. The interactive, case-based, multiplayer web-based game allows service providers to deepen their skills in Motivational Interviewing (MI), a widely recognized evidence-based practice that supports people to make positive behavior changes related to health, wellness, mental illness, and addiction. The Phase II randomized controlled trial's primary aim is to assess the relative effectiveness of three interventions (MI Training Only; MI Training + eBook; MI Training + SIM) in increasing provider MI knowledge and skill retention over time. During Phase II of this study, we will recruit 180 providers from 18 community agencies serving individuals who live in supportive housing, many of whom have histories of mental illness, addiction, homelessness, and medical problems. After receiving a standardized two-day onsite MI training, participants will be randomized into one of three conditions: 1) MI Training Only; 2) MI Training + eBook (an online comparison with comparable information to the Simulator without the interactive elements); or 3) MI Training + Simulator. The longitudinal, mixed methods study will assess providers' acquisition and retention of MI knowledge and skills through surveys and coding of standardized client interviews; barriers and facilitators of MI implementation via focus groups; organizational-level data via key informant interviews and site visits; and client outcomes for 3,600 clients through surveys, administrative, data and focus groups.
