Active clinical trials for "Acquired Immunodeficiency Syndrome"

Increased comorbidities such as cardiovascular disease (CVD), are emerging problems in HIV infection but the mechanisms are unclear. Understanding how antiretrovirals can minimize morbidity in treated HIV infection is a research priority. Nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) are included in all HIV treatment regimens. Tenofovir (TFV) disoproxil fumarate (TDF) has been associated with an increased risk of nephrotoxicity and bone disease compared with other NRTIs. Tenofovir alafenamide (TAF) is an oral prodrug of TFV, but is more stable in plasma as compared with TDF and lower plasma levels of TFV are thought to lead to the favorable safety profile of TAF. Mitochondrial dysfunction has a key role in HIV pathogenesis and may be the common denominator that drives pathogenesis of several comorbidities. Despite the better safety profile of newer (such as TDF) compared to older NRTIs, there are concerns for the potential for longer term toxicity of NRTIs since the exact cellular effects of NRTIs remain unclear. It is unknown whether a four-fold increase in intracellular drug levels seen in peripheral blood mononuclear cells (PBMCs) with TAF may increase toxicity in mitochondria. Better understanding of these effects could provide insights into mechanisms of HIV pathogenesis and selection of NRTIs that improve morbidity in chronic HIV infection. Hypothesis: Despite higher intracellular levels, TAF has minimal mitochondrial toxicity compared to TDF in vivo. This research will explore the relative mitochondrial toxicity of newer NRTIs (TAF, TDF) as a possible mechanism for differential NTRI-related toxicities. These data will allow selection of NRTIs that may improve morbidity in chronic treated HIV infection. Towards this aim, the investigators will use a robust experimental approach to study NRTI-related mitochondrial dysfunction using novel methods, human cell lines and PBMC. Our specific aims are: Aim 1: To evaluate the relative in vitro effects of TAF and TDF compared to an older NRTI (ddC) on 5 independent measures of mitochondrial function in the human cell line HepG2 and PBMC. Aim 2: To explore in vivo whether there is increased mitochondrial dysfunction with the use of TAF vs. TDF in chronic treated HIV infection. The investigators anticipate that the proposed experimental approach will set the basis for future large scale studies to directly compare subtle potential mitochondrial toxicities of newer NRTIs in large HIV cohorts.

CoRECT will help identify the important components of a data-sharing partnership between health departments and HIV care providers, and determine the extent to which a health department intervention can increase the number of HIV-infected persons out-of-care who: (a) link to an HIV clinic; (b) remain in HIV medical care; (c) achieve HIV viral load suppression within 12 months; and (d) achieve durable HIV viral load suppression over 18 months. We will also measure the cost-effectiveness of this intervention in regards to improved health in the individuals (re)-engaged in HIV care and reductions in further HIV transmission in the community.

The study is being conducted to assess the effect of multiple doses of BMS-663068 on the exposure of methadone in subjects on a stable dose of methadone, and the exposure of buprenorphine and norbuprenorphine in subjects on a stable dose of buprenorphine and norbuprenorphine.

The purpose of this study is to evaluate how BMS955176 affects pharmacokinetics (PK) of Dolutegravir (DTG) and also how DTG administration affects the PK of BMS955176

Background: This is a pilot randomized clinical trial (RCT) to demonstrate the feasibility and acceptability of a structural and behavioral intervention to reduce mortality following hospital discharge for people with HIV (PWH) in South Africa. Investigators' prior study showed that among 121 PWH discharged, 54% were readmitted and 26% had died by six months following discharge. In the prior study, investigators identified that missing clinic visits after discharge was associated with death. Here investigators are seeking to overcome key barriers in piloting a home-based post-hospital care intervention. Investigators' approach is informed by a conceptual model of key barriers to the care transition along with a behavioral explanatory model, the Behavioral Model for Vulnerable Populations. The overarching goal of this study is to tailor and pilot the intervention that shifts initial post-discharge care from the out-patient clinic to the home and provides patient-centered counseling (Home Link intervention). For the intervention to prove effective it will need to substantially reduce post-discharge mortality. Specifically, in the Home Link intervention, a team will conduct home visits to (1) provide a structured clinical assessment; (2) reconcile medications, (3) provide psychosocial support through patient-centered counseling, and (4) assess home needs (food security). These visits will start one week after discharge and be repeated every two weeks until the participant is stabilized and ready to initiate lower intensity clinic-based services or three months have elapsed. Aims: The aims of the study are to pilot a randomized clinical trial of home delivery of health services during the post-hospital period for PWH. Methods: This project is a pilot randomized clinical trial (RCT) to refine and test the feasibility, acceptability, and preliminary effectiveness of the HomeLink intervention. At the conclusion of the R34 grant period investigators will have a protocol and procedural manual ready for a full RCT powered for effectiveness. Significance: The proposed study is consistent with NIH HIV/AIDS highest priority research and the South African National Strategic Plan on HIV, tuberculosis (TB), and sexually transmitted infections (STIs) 2017-2022. The research addresses the HIV/AIDS Research Priority of "retention and engagement in these services, and achievement and maintenance of optimal prevention and treatment responses."

This study aims to recruit 20 participants who will take the combination anti-HIV drug tenofovir+emtricitabine (TDF/FTC) at specified times. Participants will then provide biologic samples for the measurement of anti-retroviral drug concentrations in various body compartment sites. Participants will be involved in the study for up to 24 weeks.

The overall goal of this pilot study is to evaluate the feasibility of the Lumme smartphone app for smoking cessation in people living with HIV (PLWH) and evaluate its effect on smoking cessation. Mobile health (mHealth) technology can be used for achieving health equity in vulnerable groups because it is a widely available and relatively inexpensive tool for health behavior change and can be adapted to meet the needs of its end-users. Therefore, a mHealth intervention such as the Lumme App proposed through this study is timely, relevant, scalable and likely to improve health outcomes in PLWH who smoke.

Premised on the National AIDS Strategy's focus on identifying new HIV infections through increased HIV testing, the purpose of this formative pilot study is to develop and test an integrated HIV self-testing strategy that utilizes a simplicity-model approach to HIV self-testing in emerging adult sexual minority men of color.

The investigators hypothesize that routing algorithm based ART delivery will be acceptable, efficient and improve health outcomes, specifically through meeting client needs, retaining HIV-positive persons in care, and achieving high ART resupply and viral suppression. They also hypothesize that a fee for home delivery will improve retention and viral suppression among persons willing to pay a fee for ART delivery. The investigators propose to test ART delivery using routing science and fee for home delivery as strategies that could be scaled-up to sustain lifelong ART.

The general objective of this study is to evaluate HAART adherence in Estonia and the factors affecting adherence; and the impact of an individual adherence enhancement counselling and treatment monitoring model (Advanced Adherence, AdvAdh), compared to the regular counselling received by HAART patients.
