Filter by:There is a need to identify and test effective strategies to reduce meth use and human immunodeficiency virus (HIV) risk behaviors in heterosexuals. This project will compare the efficacy of a manually-driven HIV testing and counseling (HIV T/C) intervention, with HIV T/C plus a manualized Contingency Management (CM), with HIV T/C plus CM plus a manualized Strengths-Based Case Management (CM/SBCM) model. As HIV T/C is the standard of care, the investigators are testing to determine if the investigators can enhance this standard. The specific aims and hypotheses of this protocol are: 1. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on reducing drug use, specifically meth use. Hypothesis 1: CM/SBCM will reduce drug use more than those in CM (which will have more reduction than HIV T/C), potentially mediated through increased service utilization. 2. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on reducing HIV and STI risk behaviors, specifically sex risk behaviors but also needle risk for injection drug users (IDUs). Hypothesis 2: CM/SBCM will have greater decreases in HIV risk behaviors than those in CM (which will have greater decreases than HIV T/C), potentially mediated through reduced drug use. 3. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on improving mental health status. Hypothesis 3: CM/SBCM will have greater improvements in mental health status than those in CM (which will have greater improvements than HIV T/C), potentially mediated through increased service utilization and reduction of drug use, and potentially moderated by baseline meth use.
The purpose of this study is to determine whether the availability of home self-testing for HIV will increase HIV testing frequency among men who have sex with men without negatively impacting their risk for HIV acquisition.
HIV vaccines are designed to create an immune response to certain components of the HIV virus called peptides. Previous research indicates that one peptide, called Gag, may be particularly important for stimulating an immune response to HIV. Many vaccines being studied combine multiple peptides, but including other peptides may weaken the body's response to Gag. This study will test whether a vaccine that targets Gag and another peptide called Env is better than a vaccine without Env at causing an immune response to Gag.
Using a randomized clinical trial (RCT), this study is designed to assess the effectiveness of HIV (human immunodeficiency virus) risk-reduction interventions targeting injection drug users (IDUs) in three Ukraine oblasts (regions). The investigators propose to compare the effectiveness of a revised and updated manually-driven HIV testing and counseling intervention, the Counseling and Education (C & E) model developed by NIDA, with the C & E plus a manualized network intervention. At each site, Odessa, Donetsk and Nikolayev, 250 "index members" and 500 of their network members will be recruited through street outreach over a 32-month period and randomly assigned to C & E alone or C & E plus the network intervention. Participants will be tested for drug metabolites, interviewed using ACASI (Audio Computer-Assisted Self-Interviewing), and given a rapid test for HIV at baseline, 6 and 12-months. At six-months, network members will be asked to recruit two others they inject with but who are not in the study. Primary outcomes include knowledge, self-efficacy, injection and sex-related risk behavior reduction and partner disclosure among indexes and primary and secondary network members and intervention diffusion to secondary network members. The investigators hypothesize more positive and significant change, including injection and sex risk reduction, intervention diffusion, and partner disclosure, among indexes as well as first and second network members in the network plus C & E arm compared to C & E alone. Specific aims include: 1. To compare the effectiveness of the C & E alone with the additive effect of a network intervention plus C & E in increasing knowledge about HIV and increasing self-efficacy to practice safer injection and sex-related behaviors among indexes, primary and secondary network members. 2. To assess the effectiveness of the C & E alone with the additive effect of a network intervention plus C & E in reducing drug and sex risk behaviors among indexes, primary and secondary network members. 3. To compare the extent of intervention diffusion to second wave network members in the two arms. 4. To evaluate the extent of disclosure by HIV positive indexes and network members in the two arms
This study will compare the efficacy and safety of ATV/r at either 200/100 mg or 300/100mg given daily in Thai patients in combination with 2NRTIs.
The purpose of this study is to study and compare the pharmacokinetics profile of low dose raltegravir (RAL) (400mg OD and 800mg OD) and standard dose of 400mg BID in Thai HIV-infected patients.
Optimal development of sustainable health systems must use locally relevant infrastructure. Mobile phone technology, driven primarily by local market forces rather than foreign assistance, is spreading rapidly through African communities to improve people's personal and business communications. Here, the investigators propose using a structured mobile phone communications system for prevention of mother to child transmission of HIV (PMTCT). The system is designed to improve antenatal linkage to care, provide reminders to take PMTCT medications, and improve post-natal support and follow-up, even when mothers deliver at home. In addition to benefits in PMTCT related outcomes, this model allows evaluation of the intervention in a public health setting with the ultimate goal of advancing regional health systems development. The overall goal of of the study is to assess if mobile phones and SMS text messages can be used to help improve prevention of maternal to child transmission (PMTCT) of HIV services by strengthening health systems. Specific objectives are: 1. To determine if mobile phone SMS text messages can demonstrate an improvement in compliance with a known intervention ( use of nevirapine) for PMTCT, demonstrated by: 1a) improved antenatal care attendance (greater than 4 visits) 1b) increased usage of nevirapine in labour (from 60% to at least 70%) 1c) earlier identification and treatment of HIV positive infants 1d) increased postpartum care for HIV positive mothers 1e) acceptability of cell phone SMS text messages transmission of information among HIV positive women 2. To demonstrate that mobile phone technology can be used as an effective tool to strengthen PMTCT health information systems at the facility level by: 2a) determining factors that constrain or promote the use of cell phone technology to strengthen PMTCT health information systems from the perspective of patients, health care providers and policy makers 2b) determining how cell phones can be used as a tool to generate equity statistics for PMTCT programs and formulate equity orientated PMTCT policies 2c) determine if early involvement of policy makers in the study improves knowledge translation
This is a randomized, open label, phase II trial to evaluate the safety and immunogenicity of two different schedules of vaccination against influenza A H1N1 in HIV-infected individuals, in which each of the randomized groups will be compared with HIV-negative volunteers vaccinated with the regimen indicated by the Brazilian National Immunization Program. Will be included in the study HIV-infected patients, stratified by CD4 count (< 200 cells/mm3 or > 200 cells/mm3) at the time of screening for the study, not receiving antiretroviral therapy treatment or receiving stable treatment for at least 8 weeks, with no plans to change over the next 6 months, eligible to receive vaccine against influenza A H1N1. The control group will be formed by HIV-negative individuals, confirmed by serology performed at screening, eligible to receive vaccine against influenza A H1N1. Patients infected with HIV will receive one of two possible vaccination regimens: 1) 3.75 µg in two applications 21 days apart, 2) 7.5 µg in two applications 21 days apart. The volunteers in the control group will receive a single application of 3.75 µg dose of the vaccine. The study's hypotheses are: 1) The vaccine against the H1N1 virus promotes antibody titers above the level specified for protection (seroconversion), being as safe and well tolerated in patients HIV-1 infected as in non HIV-infected volunteers; 2) The proportion of seroconversion for H1N1 virus vaccine at a dose of 3.75 µg in HIV-1-infected patients is similar to the proportion of seroconversion induced by the same vaccine at a dose of 7.5 µg; 3)The proportion of seroconversion with one dose of the vaccine against H1N1 virus is similar to the proportion after the second dose.
The aim of the study is to observe the tolerability and effectiveness of Kaletra in Human Immunodeficiency Virus/Hepatitis-B Virus and Human Immunodeficiency Virus/Hepatitis-C Virus co-infected patients.
This is a five-part study that will take place in the Bronx, NY, and Washington, D.C. The different components of the study will focus on increasing the number of people being tested for HIV, evaluating ways to link HIV-infected people to HIV care sites, evaluating methods to reinforce antiretroviral therapy (ART) adherence, and evaluating a counseling program that focuses on HIV prevention.
