Filter by:The study aims to evaluate the virological effectiveness of a third-line regimen combining dolutegravir (DTG), ritonavir-boosted darunavir (DRV/r) and optimized NRTI in Cambodian HIV-infected adults, who failed a protease inhibitors (PI)-based second-line regimen despite 3 months of boosted adherence counseling (BAC).
Background: With the advances in treatment and clinical care, individuals with human immunodeficiency virus (HIV) infection have experienced an increase in life expectancy. Liver disease is common among HIV-infected patients due to the shared routes of transmission of HIV and viral hepatitis. Nonalcoholic fatty liver disease (NAFLD) is the most common cause of elevated aminotransferases in HIV-monoinfected adults without HBV or HCV. Vibration-controlled transient elastography (VCTE) has been shown to have good sensitivity and specificity for assessment of liver fibrosis in HIV and viral hepatitis coinfected patients, as well as in HIV-negative NASH population. Controlled attenuation parameter (CAP), a novel physical parameter developed using the postulate that fat affects ultrasound propagation, measures the ultrasound attenuation at the center frequency of the FibroScan®. Study design: This is a prospective observational study. Objective: The aim of this study is to evaluate the liver steatosis and fibrosis in HIV-infected patients by noninvasive methods of VCTE and CAP. Methods: Patient number: 200 Inclusion criteria: 1. Age: 20-65 years 2. Males and females with HIV infection diagnosed by infection doctors 3. Willing and able to comply with the study requirements 4. Willing and able to provide written informed consent to participate in the study Exclusion criteria: 1. Pregnancy 2. Unable to complete the noninvasive procedure of VCTE and CAP 3. Unwilling to provide written informed consent to participate in the study
HIV cannot be eliminated and remains in the body despite the treatment that is used for HIV-infection called antiretroviral treatment (ART). Individuals undergoing ART interruption rapidly experience virus rebound in the blood. The current alternative therapeutic strategies to antiretroviral treatment have the aim to achieve the elimination of the virus in blood in the absence of ART. New drugs associated to ART that allow the elimination of the virus in the blood after ART withdrawn are needed. In monkeys infected with SIV, the analog of HIV, the virus has disappeared from the blood after administration of a compound and cessation of ART. There is an equivalent compound in humans called Vedolizumab. The aim of the present study is to research if Vedolizumab combined with ART, in subjects without previous ART, is able to eliminate the virus from the blood after ART is not taken.
The purpose of this study is to assess the safety and effectiveness of DTG use in HIV positive pregnant women. This is a 3-year multi-site prospective observational study. Approximately, 250 HIV positive pregnant women from potential European AIDS Treatment Network (NEAT ID) sites across Europe will be enrolled. The enrollment period will be over 2 years with a follow-up period of 1 year for outcomes. The data collected will be that obtained during routine standard of care assessments; and the subjects will not undergo any interventional study procedures.
The purpose of the study is to evaluate the efficacy and safety of autologous CD34+ cells that stably express multiplexed shRNA to treat HIV infection.
In this prospective longitudinal study we aim to assess how immunologic and viral aspects of the human immunodeficiency virus (HIV) viral reservoir, established during early HIV infection and responsible for viral rebound at treatment interruption, evolve in individuals who start combination anti-retroviral therapy (cART) during acute seroconversion. Recently infected patients will be selected based on Fiebig staging for an in depth sampling protocol at different timepoints during a 2 year follow up period. Colonbiopsies, lymphnode resection, lumbar puncture, leucapheresis and repeated peripheral venous blood-draws will be performed. Immunological, virological and genome expression analysis will be performed on the gathered samples.
Frailty has been proposed as a measure of biological (as opposed to chronological) aging. In this study the investigators plan to: (1) measure frailty in a cohort of older HIV-infected individuals in Hong Kong, and its association with mortality and quality of life; (2) identify risk factors predictive of development of frailty in HIV-infected individuals in Hong Kong; and (3) determine the outcomes of HIV-infected individuals in Hong Kong with and without frailty. The following assessment will be done: 1. Physical examination including measuring height, weight, hip and waist circumference. 2. Grip strength, chair stand test, gait speed test, balance tests, and neurocognitive tests 3. Geriatric syndromes, screening for depression, disability and quality of life. 4. Blood tests during fasting state to measure metabolic parameters. This is a prospective longitudinal observational study that lasts for 10 years.
Prospective Clinical Trial of HIV+ Living Donor Kidney Donation for HIV+ Recipients
This is a 48 week study to explore the pathogenesis of HIV treatment related bone disease by using a novel imaging technique, 18F-Fluoride Positron Emission Tomography (18F-PET/CT), which measures regional bone formation. The study will include other standard methods (serum bone markers and DXA) for comparison. Patients enrolled will have baseline, week 24 and week 48 assessment, with baseline being the date of replacing tenofovir disoproxil fumarate (TDF) in their HIV treatment regimen with tenofavir alafenamide fumarate (TAF), compared to a control group continuing TDF. Allocation to change to TAF or continue TDF will be randomised to allow an unbiased assessment of bone changes.
This project has the potential to improve the implementation science of treatment as prevention and pre-exposure prophylaxis uptake as a public health strategy for reducing new HIV infections in the United States. The investigators will develop and pilot test an intervention that combines messages sent over social media plus a newly developed interactive website specifically developed by and for Black/African American and Hispanic/Latino MSM to encourage treatment as prevention and pre-exposure prophylaxis use. Findings from this research can guide policy guidelines and recommendations for treatment as prevention and pre-exposure prophylaxis uptake for high-risk groups.
