Filter by:A randomized trial to test the feasibility and acceptability of an intervention to improve retention in HIV primary care in HIV-infected Hispanic immigrants compared to a "treatment as usual" condition. We will measure feasibility, acceptability, study retention, and effect sizes of outcomes in order to inform a larger trial. The intervention design is based on qualitative research with HIV-infected Hispanic immigrants and their HIV providers. The intervention will be led by a Spanish-speaking community health worker trained in HIV health promotion.
This study is being conducted to determine if the uptake of anti-HIV medications called Genvoya® and darunavir is different at several body sites, including mucosal tissues.
The conventional way to control HIV infection is the usage of a drug cocktail capable of suppressing the viral replication cycle, commonly known as antiretroviral therapy (ART). Despite effective ART it is not possible to eradicate HIV. The virus hides in particular cells to form the latent HIV-reservoir.[1-9] Studies that emphasise on revealing hidden reservoirs would aid in designing novel therapeutic strategies for controlling HIV infection. Molecular imaging by SPECT/CT has the potential to reveal hidden reservoirs of HIV virus that are not eliminated by currently used drugs capable of suppressing and thereby controlling the viral replication cycle in HIV infected patients. New approaches, necessary to prevent and treat HIV-1 infection, are gradually emerging. A new generation of highly potent broadly neutralizing antibodies (bN/Abs) may represent a promising approach to combating HIV-1 infection.[10] The broadly neutralizing antibody 3BNC117 antibody that can mimic human CD4 binding targeted against the HIV gp120 envelope protein has been tested in various clinical trials.[11-14] It has found to be safe and effective in reducing viraemia and to improve host humoral responses in HIV-1 infected individuals, and to have effect on viral rebound in patients who are kept off antiretroviral treatment briefly for experimental purpose. Imaging of simian immunodeficiency virus (SIV) infection by PET/CT has been successfully performed in nonhuman primates with a 64Cu-labeled SIV gp120-specific antibody called 7D3.[15] This study aims to use a similar approach in human with the 3BNC117 antibody. The 3BNC117 antibody has been successfully radiolabeled with iodine 123. The half-life of this radioisotope is appropriate for antibody imaging in nuclear medicine. Radiolabeled 123I 3BNC117 was shown to keep a good immunoreactivity for gp120. By using state of the art SPECT scanner a semi-quantitative image will be obtained. In addition, the absence of any chelator and the well known use of iodine-123 in clinic make it suitable for human intervention. No HIV imaging in human has been achieved yet, which is however fundamental to understand some key steps in the pathogenesis of HIV-induced immunodeficiency. This research opens promising opportunities for drug and vaccine development. Indeed, identification of virus reservoirs in treated patients would facilitate the development of strategies for eradicating these reservoirs or for extending latency period.
Wake Forest University and its partners, Triad Health Project, and the University of North Carolina, Greensboro, will be evaluating the effectiveness of ChiCAS (Chicas Creando Acceso a la Salud or Girls Creating Access to Health), a locally developed, Spanish language small group behavioral intervention that promotes access to and participation by Hispanic/Latina transgender women who are HIV negative and who have sex with men in pre-exposure prophylaxis (PrEP), medically supervised hormone therapy, and consistent condom use.
This demonstration project will assess the acceptability and feasibility of pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) as part of a comprehensive HIV prevention package in community-based clinics in West Africa. An interventional, open label, multidisciplinary and multicentre cohort study will be performed in Burkina Faso, Côte d'Ivoire, Mali, and Togo. All MSM enrolled will benefit from a comprehensive HIV prevention package including quarterly clinical examinations, screening and treatment of STIs, screening of HIV, PrEP (daily or on-demand, according the participant's choice), immunisation against hepatitis B, individualised peer-led support (for adherence and prevention), group discussions, condoms, and lubricants.
Prospective cross-sectional study at the outpatient clinic (OPC) of the Bagamoyo District Hospital (BDH) in Tanzania. Assessment of basic epidemiological data (Point prevalence and risk factors) on CKD with simple clinical, laboratory tests and the patients history. After informed consent blood samples are taken for complete blood count, serum creatinine, HbA1c, HIV-Screening, and urine samples for dipstick, urine sediment, and albumin-creatinine ratio. Further, office blood pressure, weight and height are taken. Further, patients history are asked by a questionnaire (i.e.history of infectious and cardiovascular diseases and basic demographic data: i.e. sex, age). CKD is defined as the presence of either impaired kidney function and/or albuminuria based on a one-time measurement. Primary outcome of the study are prevalence rates of CKD and the impact of non-communicable and communicable disorders on CKD.
The overall aim of this R34 application is to adapt and feasibility test an evidence-based HIV prevention education for high-risk, underserved rural women in Appalachia. This study has potential to make a significant contribution to science by advancing knowledge on the use of social media to increase access to prevention interventions to reduce high-risk substance use and related health disparities among rural women during a time of emerging and significant public health risk in Appalachia. Successfully accomplishing study aims will respond to a critical and unmet need to increase access to prevention interventions using social media, as well as advance knowledge about the high-risk drug use behaviors among vulnerable populations.
This study evaluates an educational web-based intervention designed to increase adolescent boys' and girls' motivation and skills to engage in safer sexual behavior (HEART: Health Education and Relationship Training). Half of participants will receive HEART and half of participants will receive Growing Minds, an attention-matched control website focused on growth mindsets of intelligence and self-regulation. The ultimate goal of this work is to help youth reduce their risk of HIV and other sexually transmitted diseases and to avoid unplanned pregnancies.
The persistence of an aberrant state of immune activation and inflammation (pIA) may contribute to the emergence of serious non-AIDS events which carry a higher morbimortality in HIV-infected patients. Although combined antiretroviral treatment (cART) reduces both cellular and soluble activation markers, it fails to completely control pIA despite consistent plasma viral load suppression. One of the mechanisms involved in pIA is may be an incomplete suppression of viral replication not reflected by plasma viral load, which only reflects a balance between viral replication and clearance of HIV-RNA. In addition, low-level viremia detected in most HIV-1-infected patients despite years on cART. Unintegrated 2-LTR HIV-DNA, and cellular associated HIV-RNAs, as products of active integrated DNA transcription, support this issue. Furthermore, the key rationales behind simplifying cART are a reduction of toxicities, lower risk of resistance mutations in case of virological failure and saving costs. One of these simplification strategies is a dual therapy which, based on the data up to date and in our clinical experience, has similar virological efficacy than cART. However, it is unknown if this strategy could increase the persistent HIV-1 replication and, therefore, pIA. The CD4+/CD8+ T cell ratio as a marker of immune recovery, the changes in T cell immune activation, senescence, exhaustion and apoptosis, and the cellular associated HIV-DNA and -RNA would answer the question if simplification to dual therapy would provide less control of residual HIV replication and, therefore, a detriment on pIA compared to triple therapy and, therefore, would worsen the patients' long-term prognosis.
The aim of the study is to establish if human immunodeficiency virus type 1 (HIV-1) infected adult participants with current virologic suppression on a >=3-drug tenofovir alafenamide (TAF) based regimen (TBR) remain suppressed upon switching to a two-drug regimen of dolutegravir (DTG) 50 milligram (mg) + lamivudine (3TC) 300 mg. This study will also provide important information regarding the safety and participant satisfaction with this two-drug regimen. The primary objective of this trial is to demonstrate the non-inferior antiviral activity of switching to DTG + 3TC once daily compared to continuation of TBR over 48 weeks in HIV-1 infected, antiretroviral therapy (ART)-experienced, virologically suppressed participants. This study also will characterize the long-term antiviral activity, tolerability and safety of DTG + 3TC compared to TBR through Week 144 and characterize the long-term antiviral activity, tolerability and safety of DTG + 3TC through Week 200. This will be a 200-week, Phase III, randomized, open-label, active-controlled, multicenter, parallel- group study. The study will include a screening phase (up to 28 days), a randomized early switch phase (Day 1 up to Week 148), a randomized late switch phase (Week 148 up to Week 200), and a continuation phase (post Week 200). HIV-1 infected adults on stable TBR will be randomized 1:1 to switch to DTG + 3TC once daily for up to 200 weeks, or to continue their TBR for 148 weeks, at which time and if HIV-1 ribonucleic acid (RNA) <50 copies per milliliter (c/mL) at Week 144, these participants will switch to DTG + 3TC up to Week 200.
