Active clinical trials for "HIV Infections"

It has been reported that peripheral and lymph node resident Cluster of Differentiation 4 (CD4)+ T cells expressing Programmed cell death protein 1 (PD-1) contribute to Human Immunodeficiency Virus (HIV) persistence during Antiretroviral Therapy (ART). In HIV-infected individuals, PD-1 expression on CD4+ T cells correlates with HIV disease progression, and loss of HIV-specific CD4+ T cell function can be reversed in vitro by PD-1 blockade. There are only a limited number of case reports describing the evolution of HIV-infected patients with concurrent oncological disease treated with immunological checkpoint inhibitors. However, this case provides very limited information on the effect of pembrolizumab on the HIV reservoir. Here, the investigators aim at describing changes in the HIV reservoir and in the HIV-specific immunity in HIV-infected patients on ART who receive immunological checkpoint inhibitors for the treatment of cancer, especially for metastatic melanoma.

To provide preliminary evidence about feasibility and acceptability of delivering PrEP to AGYW identified as potentially at high risk of HIV infection in Lilongwe city communities and two public facilities in Lilongwe, Malawi. The primary objective of the study is to assess the feasibility, acceptability, tolerability and cost of delivering PrEP among high-risk AGYW aged 18-24 years and healthcare providers in urban Lilongwe. Secondary objectives are (i) to assess the program's ability to enroll and retain a PrEP cohort for one year and (ii) measure the incidence of HIV infection among high risk AGYW in urban Lilongwe among women who decline to enroll in the PrEP study (these will be offered enrollment in the HIV incidence study).

The primary objective of this study is to compare the relative effectiveness of three web-based platforms: social media sites (e.g., Facebook), dating applications [apps] (e.g., Grindr), and informational sites (e.g., Google) to promote self-testing of Human Immunodeficiency Virus (HIV) infection among men who have sex with men (MSM) who are at increased risk of HIV exposure and/or infection. In addition, we will measure Pre-Exposure Prophylaxis (PrEP) uptake and evaluate the degree to which substance use and, separately, the participant's intention to test affect HIV self-testing and PrEP uptake. Through this research, we will also examine how participants' social media use, attitudes on HIV testing, perceptions of sexual risk behavior, medical mistrust, and stigma impact HIV testing and PrEP uptake.

This study aims to assess the feasibility and, acceptability and effects of implementing HIV testing at birth testing using point-of-care (POC) HIV nucleic acid testing (NAT) in maternity settings.

This pilot phase I trial studies how well treatment with vincristine and bleomycin affect quality of life in patients with acquired immunodeficiency syndrome (AIDS)-associated Kaposi sarcoma.

To address the critical scientific gaps in PrEP safety for transgender youth and to plan for appropriate implementation of PrEP in transgender youth communities, the study will be conducted in 3 integrated phases. In Phase 1, a pharmacokinetic (PK) study exploring the interactions of cs-HT for both TW and TM youth on TDF/FTC will be conducted. Simultaneously, in Phase 2, ethnographic data via focus groups (FGs) and in-depth interviews (IDIs) to inform the development of a tailored intervention to improve uptake and adherence to PrEP for transgender youth will be collected. In Phase 3, a small demonstration trial of PrEP use in transgender youth, utilizing the ethnographically developed intervention to improve uptake and adherence, while also monitoring renal and bone safety outcomes will be implemented. The project has the following important specific aims: Aim 1: To evaluate the differential PK of TDF/FTC in a cohort of transgender youth on cs-HT by conducting a PK trial of daily TDF/FTC among 24 TW taking estradiol and 24 TM taking testosterone (ages 15-24 years) using video-based directly observed therapy (DOT) to insure daily adherence and maximize drug exposure. Aim 2: To develop a culturally, developmentally, and gender-affirmative intervention to increase uptake of and adherence to PrEP among TW and TM youth that is grounded in theory (Information-Motivation-Behavioral Skills Model of Behavior Change, Gender Affirmation, Empowerment Theory) and incorporates the PK data from Aim 1. The investigators will conduct FGs with young TW (N=20-30) and TM (N=20-30) and conduct IDIs with participants from the PK study (Total N=10-14). Investigators will solicit continuous input and feedback from TW and TM on the project's Youth Advisory Board. Aim 3: To conduct a small randomized controlled trial within a PrEP demonstration project comparing the newly developed intervention with standard of care (SOC) in TW (N=50) and TM (N=50) ages 15-24 years.

The purpose of this study is to evaluate the impact of offering early antiretroviral therapy to HIV-positive individuals in government-managed health facilities in Swaziland on a range of economic outcomes

A total of 40 HIV infected patients will be randomly assigned into intervention or control group. Participants in the intervention group will use an smart phone application for two months. Participants will receive reminder notifications and use the app to take and send videos of themselves taking the pill(s), uploaded videos will be centrally reviewed by a study nurse . Control group participants will receive standard care. Antiretroviral Therapy adherence will be measured by self-report, pill count, and smart bottle as well as the App. Participants' perceptions of app using experience will be recorded via face to face interview.

This study tests strategies for improving PrEP implementation in maternal and child health clinics using a difference-in-difference approach.

The study is a longitudinal, observational cohort study of people who are newly-diagnosed with HIV who consent to recency testing and participate in index testing services, and their disclosed contacts. The study will evaluate the impact of recency testing on HIV positive yield of index testing among the contacts of newly diagnosed people living with HIV and the incidence of adverse events or social harm as a result of returning recency results among newly diagnosed people living with HIV.
