Filter by:This study is a phase II, multicenter, randomized, blind, placebo-controlled to evaluate the safety, tolerance, efficacy of ASC22 injection in combination with anti-retroviral therapy to treat subjects living with human immunodeficiency virus type 1.
Due to the scarcity of data on prognostic and predictive influence on CCA, epidemiological studies evaluating these factors need to be developed in patients with CCA. Therefore, the investigators want to evaluate the profile of patients in the real world and from various parts of the world, describing prognostic factors such as CD4 dosage, time of HIV infection, evaluation of viral load, diagnosis of AIDS, geographic region of diagnosis and treatment, clinical staging, medications concomitant with QRT (risk of drug interactions), comorbidities (possible impact on dose-intensity), use of HAART, time of use of HAART, radiotherapy modality (conventional 3D vs Modulated Beam Intensity [IMRT], response to Nigro vs CTII regimens, as well as comparing clinical outcomes with patients without HIV infection.
This is a randomized, double-blinded, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of single ascending dose (Part A) and multiple ascending dose (Part B) of HRS5685 tablet in healthy subjects.
Several studies among people living with HIV (PLWH) have shown more weight gain with tenofovir alafenamide (TAF) than with tenofovir disoproxil fumarate (TDF). This difference could be due to weight increasing effect of TAF and / or weight decreasing effect of TDF. When TDF is ingested, it gets absorbed in the beginning of the small intestine. TDF is processed into free tenofovir (TFV) within the enterocytes, whereas TAF is not. The effect of TFV on enterocytes is not known, but in kidney tubular cells TFV seems to damage mitochondria and that seems lead to TDF-associated kidney toxicity. In the present cross sectional study the investigators hypothesize that TDF but not TAF causes damage in the small intestine gut wall and that may lead to poorer absorption of nutrients and opposing effects on body weigh. Twelve stable PLWH who have been treated with TDF for at least past 6 months and 12 PLWH who have similarly been treated with TAF for at least past 6 months will be recruited. The participants will have a gastroscopy done with biopsies taken from the small intestine. These biopsies will be examined for mitochondrial damage and other potential pathological findings. In addition, blood concentrations of several nutrients absorbed from the same part of the small intestine as TDF and blood concentrations of some markers of intestinal damage will be measured.
The main objective of this prospective observational cohort study is to investigate the epidemiology, the risk factors and ultimately the incidence of novel HIV infections among individuals at high risk for acquiring HIV via sex practices.
The overall goal of this study is to determine if periodic de-worming of persons living with HIV in intestinal parasite-endemic regions will lead to decreased morbidity and mortality associated with HIV by reducing immune activation and intestinal damage associated with these diseases. The hypothesis for this project is that intestinal parasitic infections contribute to a modifiable pro-inflammatory state in persons living with HIV (PLWH). Aim 1: Determine the prevalence of intestinal parasitic infections in PLWH receiving care at an HIV-treatment center in Lilongwe, Malawi using a highly sensitive multi-parallel stool PCR test. Hypothesis: highly sensitive stool PCR testing will demonstrate that disease burden of parasitic infection in PLWH in Malawi is higher than historically reported based on stool microscopy. Aim 2: Determine the impact of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection compared with parasite-negative participants with HIV. Aim 3: Determine the impact of eradication of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH before and after treatment of parasitic co-infection. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection, and these biomarkers decrease with anti-parasitic treatment.
To stem increasing rates of HIV among gay and bisexual men in Central-Eastern Europe, the feasibility, acceptability, and early efficacy of a culturally adapted evidence-based program to introduce pre-exposure prophylaxis (PrEP) into Romania's healthcare practice will be established. PrEP Romania, a hybrid in-person + mHealth PrEP uptake and adherence program, aims to empower gay and bisexual men and their healthcare system to adopt PrEP and support adherence. Findings can inform evidence-based PrEP rollout in other Central-Eastern European countries with similar levels of unpreparedness for biomedical prevention.
The aim of the study is to evaluate the efficacy of Doravirine (DOR) in the second-line therapy for patients infected with HIV-1 sub-subtype A6 and its derivatives and having the mutations to previously used drugs
A pilot injection-setting targeted peer-driven intervention to reduce HIV and hepatitis C virus transmission and overdose risk behaviors among people who inject drugs (PWID).
HIV and Sexually Transmitted Infection (STI) rates are increasing in rural areas including rural Colorado. Many rural residents find it difficult to access HIV and STI prevention services. In this study, an online survey on HIV and STI Prevention and best practices to provide access to prevention will be administered to rural residents in three zip 3 zones in rural Colorado. In addition to the baseline survey, study participants who are interested and medically eligible may initiate PrEP services with the University of Colorado HIV Prevention Program and receive PrEP through telemedicine visits, mailed home lab kits, and mailed medication. Persistence in PrEP care, acceptability, and feasibility of telemedicine and home lab kits will be measured.
