The purpose of this study was to develop and initially evaluate an efficacious, comprehensive, culturally sensitive, women-centered model of care for pregnant South African women by adapting and refining PI Jones' Reinforcement-Based Treatment (RBT) model, at the same time integrating into it the HIV prevention components of Co-I Wechsberg's Women's Health CoOp (WHC) model, yielding an integrated treatment and prevention model, RBT+WHC.
MARCH is an international, multicentre trial planning to enroll 380 HIV-1 infected patients who are currently on 2N(t)RTI + PI/r regimen and virologically suppressed. Participants will be randomized (1:2:2) to one of three treatment groups: to continue their current treatment regimen, maraviroc dose at 150 mg twice daily with PI/r, or maraviroc at 300 mg twice daily with 2N(t)RTI. As the participants population have HIV RNA <200 copies/mL, the phenotypic assessment of tropism cannot be used to determine tropism, instead we will employ the genotypic assessment of tropism by sequencing the V3 loop of the HIV envelope. The main aim of this study is to investigate whether switching to maraviroc, in combination with either RTI or PI/r, is as good at keeping the HIV viral load undetectable as the combination of RTI with PI/r. The other aim is to see if switching to these combinations with maraviroc will improve some of the side effects that can be seen when people take combination therapy including RTI and PI/r. The study hypothesis is that in stable, virologically suppressed (plasma HIV-RNA <200 copies/mL) patients with no history of prior virological failure, a switch to either MVC dosed at 300mg twice daily (bid) combined with the same 2N(t)RTI backbone regimen or MVC dosed at 150mg twice daily (bid) with the current PI/r (or 300mg bid at the discretion of the investigator if the PI/r is fosamprenavir/r) provides similar (non-inferior) antiretroviral efficacy compared to continuation of the current 2N(t)RTI + PI/r regimen.
Adolescents with substance use disorders (SUD) are at substantial risk for contracting HIV/STIs compared to their counterparts without SUD, yet few HIV/STI sexual risk reduction interventions have been developed to meet their unique needs, and none use a family-based intervention approach, which the literature recommends as the focus for intervention for youth. Current state policies neither require providers in clinics delivering substance use treatment to offer HIV/STI sexual risk reduction nor offer providers tools or training for HIV/STI prevention. There is clear public health need to develop innovative methods of service delivery and effective strategies of HIV/STI sexual risk reduction that address multiple contexts of risk (i.e. family) for this high risk population. The current proposal addresses this need by developing a provider-delivered HIV sexual risk reduction intervention to be implemented in outpatient SUD treatment that: 1) builds the clinics' capacity to help families under their care to more comfortably address the adolescent's sexuality; 2) promotes youth's safer sex practices; and 3) reduces HIV/STI sexual risk behaviors among adolescents with SUD in care.
The goal of this study is to examine how social networks, neighborhood, and depression are related to HIV risk. The intervention is designed to train individuals to cope with feelings of depression or stress as a way to reduce their risk for HIV.
CCR5 antagonists might be an adequate alternative for HIV-1-infected individuals with suppressed viremia who experience antiretroviral-related toxicity. The assessment of HIV-1 tropism in proviral DNA could be helpful to inform in which of these subjects CCR5 antagonists could be efficacious.
Over twenty percent of HIV-positive persons in the United States are unaware of their infection, leading the Institute of Medicine to recently urge further work to compare the effectiveness of HIV screening strategies. This study will use a randomized trial to compare several variants of emergency-room-based HIV-testing policies in order to determine how HIV test acceptance rates can be increased. The testing policies will be designed using principles from behavioral economics, varying the choice architecture and offering small monetary incentives. This will be the first study to measure differences in take-up rates across a variety of promising but largely untested approaches within a unified randomized trial. Three defaults will be tested: traditional opt-in (test only those patients who request testing), opt-out (routinely testing unless patients decline), and active-choice testing (patients are required to state whether they want to be tested). The study will also be the first to test the effect of small monetary incentives ($1, $5, $10) on test take-up. An additional novel study contribution will be to test the hypothesis that compliance with large requests (accept an HIV test) increases after making a small request or pre-commitment - this "foot in the door" technique has not been previously studied in this setting. The factorial design will permit a direct comparison of all interventions, as well as interactions. The study will contribute a nuanced empirical understanding of how testing protocols from behavioral economics theory affect the effectiveness and efficiency of screening programs in an actual scaled- up setting (San Francisco General Hospital). This will assist in implementing and assessing recent CDC guidelines on HIV screening, while also more generally advancing scientific knowledge related to applying behavioral economics in comparative effectiveness research.
This study will recruit 159 HIV-infected men with alcohol use disorders (AUDs). Men will be randomized to receive either oral naltrexone for the treatment of alcohol use disorder or placebo. Men with acute, recent or established HIV infection will receive antiretroviral treatment (ART) and be randomized to oral naltrexone or placebo. The purpose of this study is to see whether use of oral naltrexone improves medication compliance, and therefore HIV viral load suppression, among men with alcohol use disorder. The study will also assess the impact of oral naltrexone on alcohol use behaviors in this population.
This study will test whether contingency management (monetary vouchers contingent on abstinence from drugs) that reinforces one behavior (achieving abstinence from drugs) leads to improved outcomes in other related behaviors (achieving HIV viral load suppression). In a randomized controlled trial, the investigators propose to test whether an abstinence-reinforcing contingency management intervention improves viral load suppression in HIV-infected drug users.
The purpose of this study is to determine the effects of vitamin D on measures of bone health and immune function in HIV infected postmenopausal women. The investigators prior research with this population revealed that low vitamin D levels are very common. Prior research with this population also revealed that Vitamin D is necessary for the body to absorb calcium and is important for the health of the bones. When vitamin D levels are low, there are increased risks of bone loss, muscle weakness, falls and fractures. Low levels of vitamin D have also been associated with impaired immune function. This study will help us learn whether two different doses of vitamin D will improve bone health and immune function.
