Filter by:The hepatitis A virus (HAV) is a significant global public health concern. The hepatitis A virus is transmitted primarily by the faecal-oral route, leading to acute hepatitis. Symptoms include low-grade fever, anorexia, jaundice, and typically resolve without complications. However, HAV infection in patients with chronic liver disease, especially those over 50 years old, may result in more severe outcomes, including fulminant hepatitis, with a higher mortality rate compared to the general population HAV vaccination is a cornerstone of prevention, especially in high-risk groups. Currently, there is a recommendation to vaccinate patients with chronic liver disease against HAV infection. However, these patients often have compromised immune responses, leading to lower vaccine efficacy compared to the general population. The goal of this randomized controlled trial is to compare the efficacy and safety of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen with an intensive 3-dose (0, 1, 6 months) schedule in patients with advanced fibrosis and cirrhosis. The main questions it aims to answer are: - Compared the seroconversion rate of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis. - Compared the antibody levels against the hepatitis A virus (Anti-HAV IgG) of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis.
The aim of this project is to set up a cross-sectional cohort study (France, Germany, The Netherlands, Poland, Spain, Switzerland, Italy, United Kingdom and Portugal) to assess the implementation of EACS guidelines for HDV-testing among PLWH with positive HbsAg and thereby evaluate the prevalence of HDV infection among HIV/HBV-coinfected in 2023, as well as corresponding risk factors. In addition to the testing itself, this study will also set up a cohort and databasee for future HDV studies among PLWH, including clinical, virological und laboratory parameters. 1. Analyze the rate of HDV-testing and evaluate the prevalence of HDV-infection by testing. 1. Evaluation of former screening of HDV by assessing existing data at study sites. 2. Determination of the HDV prevalence in European PLWH and HBV coinfection. 2. Setting up a database of all PLWH with HBV/HDV coinfection 1. Analysis of transmission risk factors for HDV coinfection 2. Asses the rate of HDV positive patients with ongoing HDV replication. 3. Define the liver disease state by APRI score, fibroscan, ultrasound and routine laboratory test results.
A randomized, double-blind, placebo-controlled Phase IIa clinical study to evaluate the safety and efficacy of GST-HG131 tablets in patients with chronic hepatitis B
This is a single-center, proof-of-concept pilot study which uses a cross-over design to compare two dietary interventions/treatments: Western Diet (WD) vs Mediterranean (MD) and impact on quality-of-life parameters in AIH. Participants will receive both treatments through two phases and will be divided into two groups.
This is a Phase II Investigator-Initiated Study to understand the vaccinal effect of HBsAg monoclonal Ab VIR-3434 in chronic hepatitis B infection. The purpose of this study is to test VIR-3434, an experimental drug that specifically targets the HBsAg of hepatitis B virus, to clear it from the body. This is an open label study and there is no placebo used in this study. All participants will receive the VIR-3434 for 48 weeks and then follow up in the study for 48 weeks. A total duration of approximately 104 weeks including screening period for the entire study.
The Partner Navigation Intervention Study is a randomized controlled study (RCT) to assess the efficacy and mechanism of action of the first behavioral intervention to increase hepatitis C (HCV) treatment initiation among adult people who inject drugs (PWID).
In humans, alcohol-related dysbiosis exists with a decrease in bacteroides. This dysbiosis is responsible for the breakdown of the intestinal barrier by a decrease in the synthesis of protective mucus, and some proteins involved in tight junctions or a decrease in defensin (Reg3b, Reg3g) which promotes bacterial growth and ultimately bacterial translocation. The microbiota of a patient with alcoholic hepatitis is different from that of a patient without alcoholic hepatitis. Acute alcoholic hepatitis has a severe prognosis and corticosteroids are the only first line therapy option, with better survival at 28 days versus placebo. However, mortality remains high at 30% at 3 months, which highlights the importance of seeking intestinal microbiota profile on treatment response. The determination of one or more intestinal microbiota signatures associated with the treatment response Corticosteroids plus FMT or Corticosteroids plus placebo will allow the clinician to have a simple and rapid test obtained in 16S RNA analysis to predict the therapeutic response and potentially the best treatment to adopt and to address medical and medico-economic stakes. The investigators will first characterize the alcohol-induced dysbiosis by a whole microbiota sequencing in the different groups. Specific bacterial species identify by DNA sequencing should be confirmed by qPCR of 16S rDNA to determine a fingerprint of sAH microbiota. Metabolic properties of intestinal microbiota, such as production of short chain fatty acids, will be analyzed by using HPLC. In the sAH group, evolution of intestinal microbiota will be observed by shotgun DNA sequencing between the day 0 and the day 7 of corticosteroids treatment. The analysis of sAH patients' microbiota (day 0) will allow us to obtain a non-responder profile to corticosteroids that can be used as a prognostic marker to use in the clinic. The deliverable is the bacterial fingerprint of the treatment response and its valuation is its use as a predictive tool of the response.
Introduction: Hepatitis C virus infection is a major cause of chronic hepatitis, cirrhosis, and liver cancer. The risk of developing cirrhosis for people with chronic infection with the virus ranges from 15% to 30% over a 20-year period. According to 2019 data from the World Health Organization there are 58 million people living with chronic hepatitis C infection. Three-quarters of those infected live in low- to middle-income countries, some of which lack budgets for screening, diagnosis and treatment campaigns. While good progress has been made in several countries, a significant gap in testing and treatment remains. Barriers to timely diagnosis include lack of awareness on the part of health professionals, availability and access to screening tests. Simplifying the cascade of care for this pathology would help ensure that more patients remain involved in the care pathway and ultimately achieve global goals. Objective: To estimate the prevalence of anti-HCV antibodies in patients with risk factors for hepatitis C virus captured by opportunity screening in the included hospital institutions. Methodology: Descriptive multicenter cross-sectional study. A total of 27160 participants among the seven institutions, 3880 per institution. Includes all persons over 18 years of age attended in the included health service provider institutions (IPS) who are users of hospitalization, emergency, outpatient and any other hospital care services. Application of a questionnaire to identify the inclusion criteria and data collection, signature of informed consent, sample collection by rapid test Abbott HCV rapid test - BIOLINE HCV and evaluation by tele-consultation by hepatologist principal investigator who will guide you to access the confirmatory test for HCV (viral load for Hepatitis C), the study will assume responsibility for its realization.
This is a randomized, double-blind Phase Ib/IIa multicenter trial. All eligible subjects will receive TQA3605 tablets or placebo in combination with nucleoside (acid) analogues. A total of 64 subjects will be enrolled.
The objective of the proposed work is to determine the seroprevalence of HEV in 2023 in a population of blood donors living in Occitania. Compare the current frequency of anti-HEV IgG and IgM markers with that of 2011. The serological techniques used and the questionnaires will be similar
