Filter by:Human Immunodeficiency Virus (HIV) infection is complicated by high rates of infections and cancers which are often the cause of death rather than the HIV/acquired immune deficiency syndrome (AIDS) virus itself. Treatment of HIV with antiretroviral medications has decreased the frequency of many complications by over 90%, but bacterial pneumonia remains extremely high. Current vaccines are not very effective in preventing these infections in patients with HIV infection. The investigators are studying the cells (B cells) that make antibodies to fight infection by binding to and killing bacteria. The goal is to understand how HIV impairs the ability of B cells to make antibodies in sufficient quantity and of sufficient quality to protect patients with HIV to learn how to enhance protection against these infections. The investigators also seek to understand the role of the bacteria (specifically Streptococcus pneumoniae) that normally live in the nose and throat in the development of pneumonia and other infections.
Participants receive culturally relevant and specifically tailored text messages based on the behavioral change theoretical constructs of Social Support Theory, Health Belief Model, and Social Cognitive Theory. Participants are randomized into one of three conditions for an 8-week intervention period: Group 1: culturally relevant theory-based text messages interactively transmitted by peer health educators (TXT-PHE); or, Group 2: the same culturally relevant theory-based text messages transmitted by automation (TXT-Auto); or, Group 3: assessment-only (AO) control with no theoretically based text messages.
The purpose of the study is to explore the treatment of patients with acute hepatitis C infection (infection acquired within the last 6 months) who are also infected with human immunodeficiency virus (HIV).
This prospective, randomized, single-blinded, placebo controlled trial will examine the safety and pharmacokinetics (PK) of a polyurethane tenofovir disoproxil fumarate (TDF) vaginal ring when used continuously for 14 consecutive days. The primary objective is to assess the safety of TDF vaginal rings when used continuously for 14 days by healthy, HIV-uninfected, sexually abstinent women, as compared with a placebo vaginal ring.
The purpose of this study is to determine if enhanced support for women and their families within facilities and/or through community outreach will result in improved retention in the continuum of PMTCT care.
Engagement in primary care for People Living with HIV/AIDS (PLWHA) is a significant public health concern because reduced commitment to care puts PLWHA at risk for illness progression, death, and transmission of HIV to others. This project will develop a novel treatment, brief acceptance-based behavior therapy (ABBT), to promote self-acceptance of HIV status as a pathway to reducing engagement barriers. The clinical and public health impact of this project will be the development of a simple, low-cost, disseminable intervention that enhances longitudinal commitment to care so PLWHA can obtain effective medical treatments that will prolong survival and improve quality of life. We hypothesize that individuals randomized to brief ABBT will showed increased longitudinal attendance of primary care appointments.
This study will evaluate the effect of chloroquine in individuals infected with HIV. Researchers will aim to determine if chloroquine treatment in participants whose viral loads are suppressed on combination antiretroviral therapy (ART), results in improved immune activation and CD4 cell recovery. The study will recruit 20 individuals and will last approximately 44 weeks. Eligible participants will receive an oral dose of chloroquine (250 mg) once daily from week 8 through week 32. All participants will be asked to have rectal biopsy samples (week 0 and week 32) to study T cell immune activation in the mucosa rectal site.
Hepatitis B virus infection is a common occurrence among patients with HIV. Effective vaccines are available, but there's some uncertainty regarding specific dosages, specially among those who have not responded to an initial vaccination. The purpose of this study is to determine the effectiveness of a simplified immunization schedule compared to a high-dose one.
This study is a pilot study to evaluate impact of Tripterygium Wilfordii Hook F (TwHF) on T cell immune activation and immune activation in HIV-infected immunological non-responders. The investigators aim to evaluate the safety and efficacy profiles of TwHF in HIV immunological non-responders.
Although poor antiretroviral (ART) adherence in HIV does not mean a complete lack of therapeutic results, the benefit of ART increases as adherence improves. Consequences of suboptimal ART adherence are viral rebound, development of drug-resistant HIV strains, and more rapid progression to AIDS. Moreover, HIV-infected persons tend to have numerous co-occurring conditions and therefore take many medications making adherence to multiple drug regimens more difficult. A mobile application capable of improving medication adherence among HIV-infected persons would be highly useful. The investigators propose an intervention study designed to address these potential mechanisms of nonadherence by utilizing the Care4Today v2.0 smartphone application (app). The current study is a small pilot Randomized Controlled Trial (RCT) comparing the smart phone application titled "Care4Today v2.0" versus standard of care to improve medication adherence to ART over a 4-week period with 60 HIV-infected participants. The pilot RCT consists of 60 HIV-infected persons who are at risk for ART medication nonadherence. Using random assignment, 30 HIV-infected participants will be assigned to medication adherence improvement via "Care4Today" app as compared to 30 HIV-infected participants assigned standard of care. The investigators will assess the effectiveness and acceptability of the app in improving objectively measured ART adherence (i.e., via medication event monitoring system caps) over a 4-week period via a pilot RCT with 30 HIV-infected persons assigned to the Care4Today intervention and 30 HIV-infected persons assigned to standard of care.
