Filter by:This study addresses racial/ethnic disparities in HIV/AIDS treatment. Many persons living with HIV/AIDS (PLHA) in the U.S. (10-19% of PLHA), predominantly African-Americans and Latinos, delay taking Highly Active Antiretroviral Therapy (HAART) until late in the course of their HIV disease or never initiate HAART when it is medically indicated. However, there are no behavioral interventions to increase HAART initiation among PLHA who delay or decline HAART ("PLHA-DD"). The overarching aim of the proposed study is to develop a flexible, targeted, and sustainable behavioral intervention to increase HAART initiation among PLHA-DD, which, if efficacious, will lead to reductions in morbidity, early mortality, and health care costs, as well as increased viral load suppression (reducing transmission to others). Further, the study complements and primes participants for existing adherence interventions, from which PLHA-DD can benefit when they initiate HAART.
This study will test the effectiveness of a behavioral intervention to increase Prevention of Mother-to-Child Transmission of HIV (PMTCT) protocol uptake among South African HIV positive pregnant women. This study will also determine whether the participation of male partners will have additional positive impact on PMTCT uptake. The intervention will utilize a combination of both gender-concordant groups and individual or couples counseling strategies, before and after birth. During antenatal care, the intervention will use a gender-concordant group format to address PMTCT information, HIV disclosure, coping with stigma, intimate partner violence, and adherence to the overall PMTCT protocol. Just prior to birth and following birth, the intervention will shift to individual or couples-based counseling, targeting medication adherence, safer infant feeding, and family planning. It is hypothesized that women attending the intervention will be more likely to properly take HIV medication before birth and provide it to their infants. Additionally, it is hypothesized that male partner involvement will further increase the likelihood that mothers will take their HIV medication as prescribed and provide it to their infants.
This study will evaluate the effects of a comprehensive approach (One4All) to increase the percentage of patients that receive their HIV testing results and counseling. Primary Hypothesis: The One4All approach will increase the proportion of individuals who have completed all tests to confirm HIV diagnosis and received counseling within 30 days of screening HIV+, given they have screened HIV+ on the initial test, from 40% to 60%.
Antiretroviral therapy (medicines used to treat HIV) can interact with hormonal contraceptives which might decrease their effectiveness. The single-rod etonogestrel contraceptive implant is being more commonly used in low- and middle-income countries because if the ease of insertion and removal. Efavirenz and nevirapine are first-line HIV medicines in Sub-Saharan Africa and this study will help determine an effective way to use these medicines with the etonogestrel implant. The investigators hypothesize that women receiving nevirapine- or efavirenz-based antiretroviral therapy will have lower etonogestrel levels in their blood after six months of insertion as compared to women not taking antiretroviral therapy.
In this project, the investigators want to analyse the capacity of Acetylsalicylic acid and hydoxychlroquin (HCQ) to induce an Immune Quiescence (IQ) phenotype, which has been previously associated with natural protection to HIV infection. This phenotype is characterized by lower expression of genes involved in cellular activation, lower resting levels of inflammatory cytokine production, lower level of systemic activated T cells, increased levels of systemic T regulatory, increased production of anti-viral anti-protease serpins at the female genital tract and reduced numbers of HIV target cells (mainly CD4+ CCR5+ T cells) in the FGT ( female genital tract). The objective of this study is to determine if daily oral administration of Acetylsalicylic acid or hydroxychlroroquin can reduce systemic and mucosal immune activation in HIV negative women.
The main objective of the study is to assess the acceptability of a future therapeutic vaccine against HIV in patients living with HIV-1. Secondary objectives concern the validation of a specific questionnaire for self-perception and acceptability of therapeutic vaccination against HIV-1 (RAVVIH), the development of a composite score for acceptability based on this questionnaire, and the analysis of critical factors related to: representations of vaccination in general, representations of therapeutic vaccination specific to HIV, perception of disease severity, health-related quality of life, doctor-patient relationship.
Our research is part of the global effort to develop a vaccine against HIV. We aim to develop a non-invasive, needle-free 'transcutaneous' vaccine. It will be a water-based solution which is placed on the surface of the skin of the upper arm, after the hairs have been stripped away. The active component of the vaccine - DNA which contains genes derived from the virus - will enter through the hair follicles from which the hair has been stripped. The DNA will get into cells, which will use the HIV genes to make copies of virus proteins. These proteins will stimulate the body's immune system and, we hope, make it able to protect against HIV infection. The research is to assess the safety of this approach, and how good it is at stimulating the immune system. We will combine the 'transcutaneous' vaccine with an 'intramuscular' version which is injected into the muscle of the thigh, and compare this combination with: intramuscular plus 'intradermal' (injection into the skin); and intramuscular with added 'electroporation' - use of a pulse of electricity to increase uptake of DNA vaccines. We will invite healthy men and women to take part in this research. Volunteers will first be assessed to ensure they are eligible to participate. A total of 30 will be enrolled and each will receive three vaccinations over the course of 12 weeks. We will assess the effects of the vaccinations by recording any symptoms experienced by the volunteers, and by analysing samples of their blood. The research will take place at the St Mary's Hospital campus of Imperial College London, UK. The DNA component of the vaccine is an experimental substance, so we will monitor very closely the wellbeing of the men and women who participate in the research.
This study will evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) administered for 12 weeks in hepatitis C virus (HCV) treatment-naive and treatment-experienced (including treatment intolerant) participants with chronic genotype 1 or 4 HCV infection who are co-infected with HIV-1. Participants who experience confirmed post-treatment virologic failure (relapse) at or before Posttreatment Week 24 may be eligible to be enrolled in the Retreatment Substudy to receive LDV/SOF plus ribavirin (RBV) for 24 weeks.
The purpose of this study is to determine the effectiveness of the HITSystem in maximizing early infant diagnosis (EID) service utilization for HIV-exposed infants and early antiretroviral therapy (ART) initiation for infants diagnosed with HIV.
This study will assess the efficacy, safety, and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) in human immunodeficiency virus (HIV)/hepatitis B virus (HBV) coinfected adults. Participants will be enrolled into two cohorts: - Cohort 1: HIV/HBV coinfected adults who are HIV treatment-naive and HBV treatment-naive - Cohort 2: HIV/HBV coinfected adults who are HIV-suppressed
