Active clinical trials for "HIV Infections"

The purpose of this study is to learn more about both HIV-1 infection and advancing age, and their association with increased risk of serious infection and impaired response to the Prevnar 13 vaccine.

Antiretroviral therapy is currently the only way to control HIV disease progression in HIV infected subjects and to prevent transmission. However a sustained virological control through antiretroviral therapy is requested for these objectives. There is currently 8-10% of patients who failed therapy for many reasons other than virological resistance including social unstability, psychiatric disorders, migrant status, drug or alcohol addictions. Because many of these vulnerabilities can be managed and patients helped for following adequately cares and treatments, study team designed the OPTICARE Program to help reduce impact of the patients' vulnerabilities. The OPTICARE study is designed as a prospective implementation interventional study which aims to improve retention in care among vulnerable HIV infected patients over 48 weeks. The OPTICARE program is a support program dedicated to patients either lost to follow up or in highly fraility situation that will offer an individualized care management to fill their gaps towards optimized care and control of viral replication. Our aim is, in patients virally failing in relation with poor adherence to care and treatment to test first part whether tracking proactively lost to follow up patients or detecting frail individuals at risk of lost to care is effective and secondly to evaluate the efficacy, the feasibility and the acceptability of an intervention tailored to each individual to get them to treatment success with viral suppression. In our context, a randomized approach would not be seen as ethical or possible in an environment where investigators need to evaluate such intervention as a pilot approach. Investigators therefore enrolled patients in a cohort population study OPTICARE program aim to actively identify vulnerable HIV+ population and promote optimal access to health care to this population using retention in care program in order to enable long term HIV infection control. The primary objective is to assess the feasability and the effectiveness of the OPTICARE program. The OPTICARE program aims to propose an individualized care to vulnerable HIV infected patients (UNAIDS/Second 90% goal) and to drive them to treatment success (UNAIDS/Third 90% goal) within a one-year period.

Background Lack of breastfeeding, at a minimum, doubles the risk of infant death in the first six months of life. Many infants in low resourced settings at high risk of infectious disease morbidity and death are deprived of the immunological and nutritional benefits of breast milk, through an attenuated duration of breast milk exposure. South Africa has one of the lowest exclusive breastfeeding rates in Africa, 8% in infants under 6 months of age. Mobile phone text messaging as a simple, low-cost intervention improves medication adherence among patients with HIV, diabetes and tuberculosis. Motivational interviewing has been beneficial across many health problems, including HIV viral load suppression, body weight loss, and alcohol and tobacco use. Combining a number of intervention approaches is more likely to influence behaviour change than an individual approach. Investigators assume that continued breastfeeding is sustained among women living with HIV receiving weekly text messages combined with motivational interviewing and that this contributes to improved infant health outcomes. Objectives: To determine the effects of mobile phone text messaging combined with motivational interviewing versus standard of care on: (a) Continued exclusive breastfeeding to six month of child age, (b) Continued any form of breastfeeding to 6 month of child age. To determine the contribution of the combined intervention on improved infant health outcomes: (a) Infant morbidity (all -cause hospitalization) and death (all -causes, (b) Infant growth. Methods Investigators propose a group sequential clinical trial to determine whether text messaging combined with motivational interviewing will prolong breastfeeding and the contribution of the combined intervention on improved infant health outcomes. The study will recruit 275 women living with HIV and HIV exposed infants at birth and randomly assign study interventions for 6 months.

The Managed Problem Solving (MAPS) behavioral intervention is an EBP for behavior change in people living with HIV (PLWH). The investigators propose that MAPS can be delivered by trained Community Health Workers (CHWs). The use of CHWs to deliver MAPS is justified by their ability to develop trusting relationships with their clients and the need for task shifting in busy clinics. In order to also address retention in care, the investigators will adapt MAPS to also focus on problem solving activities tailored toward retention in care (now termed MAPS+). CHWs will be located in clinics to implement MAPS+ to improve viral suppression and care retention in PLWH. Data-to-care allows for identification of people who are lost to care and link these patients back to care. Currently, medication adherence and retention in HIV care are not targeted in data-to-care so the investigators will build on this approach to facilitate the identification of PLWH who are out of care and not virally suppressed to offer them MAPS+. The set of implementation strategies include task-shifting the delivery of MAPS+ to CHWs, providing the CHWs training and ongoing support, and increasing communication between the CHWs and medical care team via standardized protocols. The investigators will conduct a hybrid type II effectiveness-implementation trial with a stepped-wedge cluster randomized design in 12 clinics to test MAPS+ compared to usual care using a set of implementation strategies that will best support implementation. Each clinic will be randomized to one of three implementation start times. Baseline (usual care) data will be collected from each clinic for 6 months, followed by MAPS+ and the package of implementation strategies for 12 months, in three cohorts of 4 clinics each. Aim 1 will test the effectiveness of MAPS+ on clinical effectiveness outcomes, including viral suppression (primary) and retention (secondary). Aim 2 will examine the effect of the package of implementation strategies on reach. Implementation cost will also be measured. Aim 3 will apply a qualitative approach to understand processes, mechanisms, and sustainment of the implementation approach. The results will guide future efforts to implement behavioral EBPs across the HIV care continuum, consistent with the "treat" pillar of EHE, and move the science of implementation services, consistent with NIH strategic priorities.

The community-based ART delivery (CAD) model will build on the existing framework to engage community action, operationalized in the current Global Fund-supported project. Community Action Workers (CAW), who are assigned to ART centers and conduct outreach work, are well-suited to administer CAD scheme. KHANA and the project partners all have implementation roles in the Global Fund-supported project and established working channels with the CAW. While the previous experiences suggest the CAD model's effectiveness, implementing it in Cambodia requires adaptation to its specific local context. The proposed project will be implemented as an implementation study in nine ART sites and supported by a concrete evaluation plan. KHANA Center for Population Health Research will lead the research component. The project has three strategic areas and corresponding deliverables as follows: A. The development of a locally-fitted model: bringing ART closer to the people living with HIV B. The research: formulation, evaluation, documentation, and dissemination of the evidence, knowledge, and lessons learned C. The scale-up: advocacy for the SOP development to replicate/scale-up the CAD model The project will benefit a wide range of stakeholders. The approximately 2,000 ART clients enrolled in the nine selected clinics will face less cost, time, and discrimination, which will also benefit their families. The clinics will have a reduced workload on site, and they would be able to improve the quality of care for the visiting clients. The Cambodian health system will obtain a CAD model tailored to the country's local context and develop Standard Operating Procedures for the scheme with readily involved stakeholders. The scale-up of the model will benefit all other ART clinics and clients in the country. The 36-months project starting from June 1, 2019, will include six months of start-up and baseline assessments, 24-month intervention, and six-month evaluation.

Gut bacterial community diversity and composition, immune recovery and activation in peripheral plasma/mucosa, plasma levels of gut damage, microbial translocation and inflammation at baseline and after 6 months of receiving intervention will be analyzed.

The purpose of this study is to learn whether having the AMP Study antibody (called VRC01) in a person's body might help their immune system control HIV better, even without HIV medication called antiretroviral therapy or ART, if they get HIV. This study will evaluate the viral and immune system responses in an Analytical Treatment Interruption (ATI), in participants who received VRC01 or placebo and got HIV while enrolled in HVTN 703/HPTN 081 (NCT02568215). Participants in this study will stop taking their HIV medication. They will stay off HIV medication unless and until the HIV levels in their blood show that their immune system is unable to control the HIV or they meet other ART re-start criteria as noted in section "Detailed Description". While they are not taking HIV medication, their HIV levels will be tested frequently, and their health will be monitored closely. This is called an analytical treatment interruption, or an ATI. An ATI is an experimental procedure that is only used in carefully monitored research.

The Pilot Test (AKA Study B) will entail a pilot randomized, controlled trial (RCT) of an mHealth behavioral intervention, LetSync, with 80 couples (N=160) to assess its acceptability, feasibility, and preliminary impact on retention in care and ART adherence as measured by antiretroviral concentrations in hair. Participants in the intervention arm will use LetSync v1.0 for 6 months and provide acceptability and feasibility data. In the ensuing 2 months, the investigators will make refinements based on participants' data to produce LetSync v2.0. Then, participants in the waitlist-control arm will receive LetSync v2.0, use it for 6 months, and provide acceptability and feasibility data. The intervention arm will continue using LetSync v1.0, for a total of 14 months. Based on acceptability and feasibility data from waitlist control arm participants between T3 and T4, the investigators will develop LetSync v3.0, which will be used for efficacy testing in a full RCT trial in the future.

The purpose of this study is to use information technology (IT) to support the delivery of HIV prevention and care best practices in the dental care setting to meet the Department of Health and Human Services (DHHS) Ending the HIV Epidemic (ETE) goals.

The aim of the trial is to evaluate in ANRS CO6 PRIMO cohort participants if the presence of the MHC B35 (53) Bw4TTC2 genotype favors the control of HIV infection (defined by a viral load (VL) less than 400 cp/mL) after discontinuation of antiretroviral therapy (ART) initiated during primary HIV infection. The trial will be a pilot "proof of concept", one arm, multicenter, nested in the ANRS CO6 PRIMO Cohort, in which the intervention is treatment interruption (of at least 6 months). It is planned to include between 20 and 50 participants.
