Filter by:Unfortunately, people most at risk for HIV are the least likely to enroll and remain in prevention programs. In our past work, we have learned how to increase enrollment in such programs among this group. We have identified and addressed previously ignored gender-specific and client self-validation issues that conventional interventions often leave not only uncontrolled, but often biased against participation. The present work will extend these methods from enrollment to retention. We intend to recruit a sample of 656 at-risk participants through our collaboration with the Duval County, FL Health Department for our randomized, double-blind trial. Our study will investigate if a meta-intervention video designed for empowering participants as agents of their own change can increase the number of attended sessions relative to a control condition without such a video. This trial will also determine if a meta-intervention video addressing various emotional/social and instrumental benefits of an HIV-prevention-counseling intervention can also increase the number of attended sessions. These two factors will be crossed, and their effects on retention will be estimated for different genders and ethnicities. Effects on clients' attention to the return sessions as reported by the counselor will also be explored among participants who return. We will also conduct mediator analyses for investigating if the meta-intervention has mediating influences on corresponding expectations about the return counseling session. As the inclusion of meta-cognitive measures can alter the efficacy of the intervention, half of the sample will receive measures immediately (0-10 minutes) after exposure to the meta-intervention, before attendance to the next session is registered. The other half will not complete these measures.
This is a phase II, proof of concept, randomized, double-blind, placebo-controlled study to evaluate the protective efficacy against TB disease, safety, and immunogenicity of MVA85A/AERAS-485 in healthy, HIV-infected adults. This study consists of 650 adults subjects (ages 18-50 years of age inclusive) who will receive study vaccine or placebo at Study Day 0 and again 6-9 months later. Samples for real-time evaluation of immunogenicity were to be collected from 70 subjects (immunogenicity analysis set).
The protocol, approved by the Rwanda National Ethical Committee, was issued to assess the safety and efficacy of the circumcision device for applying it to the national scale up of adult male circumcision in Rwanda
The investigators hypothesize that switching to a regimen based on efavirenz will be as effective and safe as remaining on a regimen based on Lopinavir/ritonavir for HIV-infected children. The investigators propose an unblinded randomized clinical trial to evaluate a simplification, protease-inhibitor (PI)-sparing treatment strategy among nevirapine (NVP)-exposed HIV-infected children treated initially with lopinavir/ritonavir (LPV/r). HIV-infected children aged 3-5 years, who have a history of exposure to NVP as part of prevention of mother-to-child HIV transmission (PMTCT), initiated LPV/r-based therapy in the first 36 months of life or who were enrolled on the control arm of Neverest 2 and who are virally suppressed with a viral load < 50 copies/ml will be included. These children will be randomized to either substitute efavirenz (EFV) for LPV/r or to continue on their LPV/r-based regimen. Eight weeks prior to the primary randomization, eligible children will also be randomized to either remain on stavudine (D4T) or switch to abacavir (ABC). Children will be followed with regular viral load and other clinical tests for 48 weeks after the primary randomization. Children in the experimental arm who have breakthrough viremia (-defined as two subsequent viral loads > 1000 copies/ml) on the EFV-based regimen will reinitiate the LPV/r regimen. The primary objective is to test whether the durability of viral suppression is equivalent when children are switched to EFV-based therapy. The primary study endpoint is failure to have HIV RNA < 50 copies/ml and/or confirmed viremia >1000 copies/ml. Secondary aims include comparison of immune preservation, toxicities, selection of resistance mutations, and adherence across the two arms. Antiretroviral drug concentrations and adherence will be investigated as possible explanations for the success and/or failure of this simplification regimen. The overall goal of the study is to contribute to the evidence base to allow expansion of treatment options for HIV-infected children in low resource settings.
The proposed study is a single-center, double-blind, randomised, placebo-controlled trial to evaluate the delivery of dapivirine from matrix vaginal rings over a 56 and 57 day period and to assess the safety as compared to placebo vaginal rings in 48 healthy, HIV-negative, sexually active women.
This protocol represents the second in human study of TUTI-16, and is being conducted to continue to gather safety and human immunogenicity (anti-HIV-1 Tat titers) data of subcutaneously administered TUTI-16.
The proposed study is a single center, double-blind placebo-controlled trial to assess the safety and tolerability of the dapivirine ring as compared to a placebo ring when inserted for 28 days in 16 healthy, HIV-negative women.
This study will investigate the prevalence and extent of both metabolic and psychosocial changes associated with the menopause transition over 1 year among women with HIV compared to women without HIV of similar age, weight, menstrual status, and ethnic background. It is hypothesized that HIV positive women will demonstrate increased abdominal fat, abnormal cholesterol and blood sugar levels, reduced bone density, and greater psychosocial challenges than HIV negative women during the menopause transition.
Current measures of adherence detect problems weeks to months after they occur. Because the HIV virus rapidly begins replicating and mutating in the absence of effective antiretroviral therapy, treatment failure may develop before an intervention can be deployed. Real-time objective adherence monitoring could redirect efforts from a reactive response to the proactive prevention of treatment failure. Because adherence is so closely associated with viral suppression, accurate adherence monitoring could also strategically limit viral monitoring only to those patients at a defined risk for viral rebound. This observational study is assessing a wireless adherence monitoring device and mobile phone-based adherence data collection among caregivers of children under the age of ten years in Mbarara, Uganda. It involves both quantitative and qualitative measures of the feasibility and acceptability of these measures, as well as circumstances of adherence lapses and other individual and cultural factors affecting adherence. The qualitative data will be used to explore models of adherence behavior, which will likely include the child-caregiver dynamic, the child's mental and physical health, and social support mechanism.
Objectives: - To evaluate the impact of genetic polymorphism on ARV drug levels - To evaluate the effect of genetic polymorphism/drug levels on long term immunologic and virologic response - To correlate the genetic polymorphism/drug levels on antiretroviral toxicities The long-term objective of this research plan is to characterize impact of pharmacogenomics to HIV drug concentration, toxicities, and response to antiretroviral therapy among HIV-infected adults. A comprehensive understanding of the impact of pharmacogenomics to HIV infection and HIV medication will lead to the development of appropriate intervention such as dose reduction strategies in patients with particular gene(s) correlated with higher drug levels. The dose reduction strategy will decrease long term drug toxicity and cost saving for Thais and Asian Ethnicities.
