Active clinical trials for "HIV Infections"

Introduction: It is well known that the infection caused by the Human Immunodeficiency Virus (HIV) is associated to a higher cardiovascular event risk. On the other hand, it is clear that the aerobic exercise training induces improvements in autonomic control and vascular function, through increases in vasodilator agents and blood vessels number. However, the investigators could not find previous works that studied the microvascular function in response to exercise training in HIV patients. Objectives: To study the impact of aerobic exercise training in endothelial function of HIV patients. In addition, the investigators will verify the association of the physical fitness to the nitric oxide bioavailability, angiogenesis and lipid profile in HIV patients. Methods: The study subjects will be composed by HIV patients, that will be randomly divided in two different groups: exercised and sedentary. The subjects will be tested before and after training in regards to endothelial function, nitric oxide bioavailability, physical fitness and lipid profile, through flowmetry, colorimetric essays, maximal cardiopulmonary exercise test, and biochemical tests; respectively. The exercise training will be performed in a treadmill for 12 weeks, 3 times a week, 40 minutes each section. Expected Results: The investigators expect to achieve markers that will help in understanding the interaction of HIV with several factors that contribute to an increased endothelial function after exercise training.

Determine the "dose-response" relationship between a cash transfer amount and HIV viral suppression at 6 months Identify the most effective cash transfer size to increase the proportion of people living with HIV infection (PLHIV) retained in care and with suppressed viral load (<1000 copies/ml) after 6 months. (This amount will be further evaluated in a cluster randomized trial in Phase 2).

To address the significant barriers to PrEP implementation for those who were assigned female at birth and self-identify as a woman and address racial inequities in HIV prevention in the United States (US), a novel approach that accounts for multilevel influences is necessary. This study is one part of a multi-component project and involves a patient-level intervention in one public health family planning clinic in Duval County Florida, where the majority of patients are women of color. The area has one of the highest HIV incidence rates among women in the US. The investigators developed a tablet-based decision support tool that helps users learn about HIV vulnerabilities and HIV prevention strategies to inform how they consider options for reducing their likelihood of acquiring HIV. Participants will be randomized to use the HIV decision support tool before their visit or standard counseling (without the use of the tool) and will be surveyed about the use of the tool, experiences with HIV prevention counseling, and intentions about the use of HIV prevention. A subset of participants, all individuals who self-identify as a woman and as Black or Latina, will also complete a post-clinic visit interview. The investigators will follow-up with participants at three months following their initial visit to see if they have initiated the HIV prevention method(s) they chose at their visit. The main outcomes will include a quantitative and qualitative assessment of PrEP or other HIV prevention use, decisional certainty, and satisfaction with information about HIV prevention options. Hypotheses: Women who use the HIV prevention decision support tool will be more likely to have initiated PrEP within 3 months compared to women who received standard counseling at the time of their initial appointment. The HIV prevention decision support tool will increase women's knowledge of PrEP and other HIV prevention methods compared to women who received standard counseling at the time of their initial appointment. The HIV prevention decision support tool will increase participants' decisional certainty in their choice of an HIV prevention method compared to women who received standard counseling at the time of their initial appointment.

The aim of this study is to examine the effect of mHealth tools on antiretroviral (ART) adherence and persistence among HIV-infected individuals with co-occurring cocaine use disorders (CUDs).

The BRIDGES Project seeks to test a program intended to help women living with HIV who face specific barriers due to culture, gender, violence, trauma, adverse mental health, and substance use to be able to better access HIV care. This program was created and tried with women living with HIV, as previously studies have indicated that women with these experiences are less likely to have stable HIV care. The BRIDGES Project will use Peer Navigators, who are other women living with HIV who have had similar experiences and have been successful in accessing care, to help other women living with HIV to access HIV care and stay in HIV care. The BRIDGES Project will also provide support to women through group sessions co-facilitated by a licensed clinical therapist and Peer Navigator. Through participation in BRIDGES, women will: (1) build skills to cope with HIV care and treatment barriers (e.g., violence, trauma, adverse mental health, substance use); (2) be connected to HIV treatment and other support services (e.g., domestic violence, mental health, substance use); and (3) learn interpersonal skills to connect with support (e.g., service providers, peers, friends, family) when faced with new or ongoing barriers.

This stepped-wedge cluster-randomized trial is embedded in an 18-month observational cohort study that has the aim to assess the operationalization of oral Pre-Exposure Prophylaxis (PrEP) in Swaziland as an additional HIV combination prevention method among individuals at high risk of HIV infection. The trial aims to determine the effect of a healthcare facility-based PrEP promotion package on the number of clients who take up PrEP.

Among the many changes associated with the impact of HIV and the long-term use of antiretroviral therapy, metabolics are important because they are important risk factors for the development of cardiovascular diseases. The objective of the present study is to evaluate the effect of the supplementation of curcumin, on the oxidation of resting energetic substrates in HIV / AIDS patients. The sample will be composed of adults living with HIV / AIDS on antiretroviral therapy for at least 6 months. Supplements will be made separately for 30 days and will be evaluated before and after the intervention the following parameters: body composition, energy metabolism, biochemical parameters and a structured anamnesis. Food consumption and the level of physical activity of the volunteers will be controlled.

Current estimates point towards a huge increase in the number of people that are eligible to start ART in Uganda and globally. As many of the newly eligible patients are largely asymptomatic, there are concerns about adherence and retention of these individuals and especially those starting ART with a higher CD4 counts. Urgent information is required to plan for implementation of most recent WHO and National guidelines in the most cost effective manner as well as maximizing retention of HIV positive individuals in care and achieving virological suppression. The investigators plan to undertake research designed to see if investigators can optimize adherence, virological outcomes and HIV knowledge, in order to give an overall increased quality of life in vulnerable populations starting or established on ART in Kampala, Uganda. The investigators will test implementation of an open source software-based tool to send text messages and to give access to an interactive voice response system using patients' mobile phones. The investigators' aim to undertake an open labelled randomised trial at two sites: the IDI which is an urban centre of excellence in HIV care, and Kasangati Health Centre, which is a peri-urban public health care facility. The project aims to enrol HIV positive patients starting ART, already established on first line ART or switching to second line ART, including special populations (pregnant women, discordant couples and young people). The estimated length of the project is 30 months. The technology to be evaluated in this study is based on CONNECT FOR LIFETM m-health technology (CFL2015.01 or higher), which provides text messages or Interactive Voice Response (IVR) functionalities, and allows a computer to interact with humans through the use of voice and tones input via keypad and offers pill reminders, clinic visit reminders, health tips and support symptom reporting. Primary Objective is to determine the effect of the CFL2015.01 tool on quality of life of HIV patients receiving care at IDI and Kasangati HCIV. At the start of the intervention, all patients will undergo quality of life assessment, which will be repeated at months 6, 12, 18 and 24 months. The scores will be compared to assess the effect of the tool on quality of life. The Secondary Objectives are virological outcomes baseline, 6, 12,18 and 24 months, retention in care, aversion of early treatment failure, disease knowledge, clinic attendance and cost analysis.

The TEACH randomized controlled trial will test the effectiveness of a collaborative care intervention directed towards physicians who provide care for HIV-infected persons to improve the quality of care for prescribing chronic opioid therapy (COT) for pain and reduce the misuse of prescription opioids among HIV-infected persons.

The objective of this research is to check whether the test drug (lamivudine in the form of coated tablet 150 mg) achieves plasma levels equivalent to those obtained from the EPIVIR in the form of coated tablet 150 mg GlaxoSmithKline administered to 28 volunteers of both genres under fasting condition.
