Filter by:The overall objective of the study is to develop and test a pilot intervention in central Mozambique to implement the new WHO "Option B+" guidelines that seek to increase the proportion of HIV-positive pregnant women in six antenatal care clinics who start antiretroviral therapy (ART) prior to delivery, and are retained in care after 90- days.
The purpose of this study is to evaluate a new approach to increase HIV testing among young adult Black, Hispanic, and white men-who-have-sex-with-men (MSM). In this randomized, controlled trial, participants will be assigned to one of three HIV testing groups: (1) rapid HIV self-testing group (OraQuick® In-home HIV Test), (2) conventional "home-based" HIV testing group (Home Access Express), and (3) community/medical-based HIV testing group. Upon completion of testing, participants will receive a questionnaire to evaluate their HIV testing experience, and also inquire about recommendations for future testing. Study participants will also have the option to refer other study eligible males to the study via email.
This is a 48-week prospective observational study that will allow testing of the hypothesis that a program in which pre-exposure prophylaxis (PrEP) is administered to young men of color who have sex with men (yMSMc) in a community youth drop-in center in conjunction with a multifaceted behavioral intervention as well as standard HIV prevention interventions can achieve at least 70% retention, as well as a medication adherence rate significantly better than that previously reported in the literature. The proposed program evaluation can provide critical information for the enhancement and scale-up of successful PrEP programs at FIGHT and elsewhere in an effort to make PrEP available to a growing number of persons at risk of acquiring human immunodeficiency virus (HIV).
The goal of ATN 093 is to determine program-level factors associated with the effectiveness of SMILE in Caring for Youth Linkage-to-Care (LTC) program network at the 15 Adolescent Medicine Trial Units (AMTU). This will be accomplished by evaluating and categorizing the various LTC programs at the AMTUs and then examining the association between the LTC program characteristics (providers, practices, and systems) and the proportion of Human Immunodeficiency Virus (HIV)-infected youth, ages 12-24 years old, inclusive, linked to care and maintained in care. As such, this study focuses on LTC programs at the AMTUs as the unit of analysis and not the youth themselves.
This is a dose escalation study to test the safety and immunogenicity of an oral HIV-1 vaccine.
1. Compare rates of seroconversion and GMTs generated following a 3-dose series of vaccine in women given low doses of vaccine by the ID route with the NFI (Group III) to those women given standard doses by the IM route with a needle and syringe (Group I) at 1 month, 6 months and 18 months following completion of the vaccination series. 2. Compare rates of seroconversion and GMTs generated following a 3-dose series of vaccine in women given standard doses of vaccine by the IM route with the NFI (Group II) to those women given standard doses by the IM route with a needle and syringe (Group I) at 1 month, 6 months and 18 months following completion of the vaccination series.
The investigators propose to evaluate a novel incentive intervention to promote suppression of viral load in people living with HIV that will employ empirically-based parameters that have been proven critical to the effectiveness of incentive interventions. Participants (N = 200) from medical clinics that serve adults living with HIV in Baltimore will be randomly assigned to an Incentive or a Usual Care Control group. Incentive group participants will receive incentives for maintaining suppressed and undetectable viral loads. The incentive program will employ high magnitude incentives, provide incentives for decreases in viral load early in treatment before a patient's viral load has reached undetectable levels, arrange frequent incentives early in treatment and reduce the frequency of incentives as participants achieve progressively longer periods of viral load suppression, arrange a schedule of escalating incentives for sustained suppression of viral load, and the intervention will be maintained for two years. Usual Care Control participants will only receive the standard HIV medical care offered in their clinic. Assessments will be conducted every 3 months throughout the two years of treatment and every 6 months throughout the year following treatment. The primary outcome measure will be the percentage of participants that have undetectable viral loads at the 3-month assessments conducted throughout the 2-year intervention period. Secondary measures will include adherence to HIV care and post-treatment outcomes. The investigators will also assess moderators and mediators of the effects of the incentives on the suppression of viral load, and conduct cost-effectiveness and cost-benefit analyses. If the incentive intervention maintains suppressed viral load and is economically sound, it could be used to improve the health of adults living with HIV, reduce health care costs, and reduce HIV transmission in the community.
Hepatitis C (HCV) is an important global public health problem, disproportionately affecting HIV positive populations. Asia and Africa account for most of the co-infection burden, but access to HCV screening and treatment is still very limited. It is expected though, with the recent therapeutic advances and increasing global advocacy efforts, that HCV treatment should become a feasible option in the near future. Sihanouk Hospital Center of HOPE (Phnom Penh, Cambodia) is catering for one of the largest HIV cohorts of the country, followed in an ambulatory settings. In this cohort, the prevalence of HCV co-infection will be determined, as well as HCV genotype diversity and the severity of liver disease. The researcher will also explore the performance of simple blood tests/panels as predictors of significant fibrosis and/or cirrhosis. Patients will attend two study-visits. All adult patients of the HIV patient cohort of SHCH will be proposed HCV testing during their next HIV follow-up consultation, following the latest algorithm of the Centre for Disease Control (CDC) (May 2013). Anamnesis and clinical examination will focus, additionally to routine practice, on presence of general and HCV liver-disease related features. Laboratory analyses will include basic HIV tests (CD4), and tests for liver function such as Hepatitis B surface antigen (HbsAg) . During the following routine HIV follow-up consultation, the results of HCV testing will be explained to the patient. If the patient is HCV negative, his/her study participation ends here. If currently infected with HCV, the clinician will repeat the HCV liver-disease (extra-hepatic & hepatic) related anamnesis and clinical examination, and prescribe additional blood tests for the non-invasive liver fibrosis/cirrhosis blood panel tests, liver and kidney function. Patients will moreover be asked to undergo a liver ultrasound and liver stiffness measurements.
The overall purpose of this study is to evaluate an intervention that aims to reduce alcohol-related HIV sexual risk behaviors among HIV-negative men in Namibia. The objectives of the study are to determine the effectiveness of an individual counseling intervention in reducing alcohol-related HIV sexual risk behaviors among men, and in reducing harmful and hazardous alcohol use among men.
This is a prospective cohort study focusing on HIV negative women. The investigators want to learn how the contraceptive methods of depot medroxyprogesterone acetate (DMPA), etonogestrel implant (Eng-Implant), levonorgestrel intrauterine device (Lng-IUD) and the ParaGard® T 380A Intrauterine Copper Contraceptive impact the vaginal immune environment.
