Filter by:This is a prospective, multicentric, non comparative study, with a retrospective data collection aiming at evaluating the efficacy and safety of bulevirtide in patients with chronic HBV/HDV co-infection with severe fibrosis injuries, or moderate fibrosis injuries associated with persistent increase of ALT.
The first purpose of this study is to test the body's protective reaction (making antibodies) to a licensed hepatitis B vaccine (Recombivax-HB) after it is injected either in the arm fat or muscle. Hepatitis B virus is an important cause of liver disease in humans. More than 21% of healthy adults over age 60 years demonstrate evidence of previous Hepatitis B infection using a common blood test. The second purpose of this study is to learn more information about other reasons (such as body fat content, gene types, etc.), why older people respond less well than younger people to vaccines. The Investigators will also learn more about the ability of certain white blood cells, called T cells, to respond to protein signals in the blood. T cells do not seem to respond as well to these protein signals as individuals age. The Investigators will compare results to a younger group of volunteers who have also been vaccinated with hepatitis B vaccine.
The current first-line treatment for HBV is long-term oral antiviral drugs to inhibit HBV DNA replication. First-line antiviral drugs recommended by the Chinese 2015 Hepatitis B Guidelines include ETV and TDF. This study is based on a real-world clinical cohort to retrospectively analyze the effects of ETV and TDF on the long-term (5-year) incidence of HCC in Chinese patients with chronic hepatitis B with compensated cirrhosis. The results will guide the revision of the Chinese HBV guidelines.
This is an open label, randomized, multi-center, comparative study. Subjects will be screened prior to study entry to establish eligibility. 100 Subjects who meet all the selection criteria will be randomly assigned 1:1:1:1:1 to (A) QL007 100 mg QD+ Tenofovir dipirofurate fumarate （TDF）300 mg QD, (B) QL007 200 mg QD+ TDF 300 mg QD, (C) QL007 400 mg QD+ TDF 300 mg QD, (D) QL007 200 mg BID+ TDF 300 mg QD, (E) TDF 300 mg QD. The purpose of this study was to evaluate the efficacy and safety of QL-007 in combination with TDF in HBeAg positive patients with chronic hepatitis b, and to recommend a reasonable regimen for phase III study.
This is an open label, randomized, multi-center, comparative study. Subjects will be screened prior to study entry to establish eligibility. 60 Subjects who meet all the selection criteria will be randomly assigned to (A) QL007 200mg BID+ Tenofovir dipirofurate fumarate （TDF）300 mg QD, (B) QL007 200 mg BID+ Entecavir 0.5 mg QD, (C)TDF 300 mg QD, (D) Entecavir 0.5 mg QD. The purpose of this study was to evaluate the efficacy and safety of QL-007 tables in combination with TDF or Entecavir in patients with chronic hepatitis b who have received nucleoside (acid) therapy, and to recommend a reasonable regimen for phase III study.
Men who have sex with men (MSM) who cured from hepatitis C virus (HCV) infection are at substantial risk of HCV reinfection. In this study, the investigators aim to evaluate the effectiveness of an online behavioural intervention, a home-based testing intervention and a combination of both on risk behaviour, and ultimately preventing HCV reinfection and onward spread of HCV.
The main purpose of the study is to compare the efficacy of two strategies aimed to rescue patients lost to follow-up with active infection or with positive HCV antibodies without RNA request to complete evaluation and prescription of treatment in cases of chronic infection. After patient identification from data files of laboratory and microbiology charts, patients will be randomized to: a) phone call, and b) invitation letter, both of two strategies including a scheduled appointment with the hepatologist.
The primary objective of this study is to determine the prevalence of AH in addition to its clinical characteristics and in-hospital mortality of patients that are hospitalized for AH in different hospitals across Latin American countries This study is carried out in different health centers throughout America, with all the countries belonging to the Latin American Association for the study of liver diseases (ALEH) more Canada and United States This would allow us to better understand the epidemiology of AH in our region and thus implement prevention measures with more solid data. Importantly, this would allow us to optimize therapeutic measures
According to the World Health Organization about 1,400,000 deaths reported annually, are related to chronic liver disease. Chronic liver disease is very prevalent in South Korea, placing a large economic burden nationwide. Subsequently, an effective and systematized approach to managing chronic hepatitis is imperative in Korea. The natural history of chronic liver disease differs greatly according to race and ethnicity. However, there is scarcity of epidemic data on chronic hepatitis based on Korean patients. Therefore, the investigators plan to establish a prospective multicenter cohort for chronic hepatitis B based on Korean patients that may be utilized for various future clinical studies on chronic hepatitis B in Korea, and thereby serve as a basis for the establishment and distribution of clinical guidelines for Korean patients with chronic hepatitis B, as part of a nationwide project supported by the Centers for Disease Control (CDC), Korea. The investigators plan to collect more than 2,000 cases per year with 6 months of regular follow-up interval as have been advised by the CDC during 10 years of the study period (from Sep. 2015) from 5 tertiary hospitals located in Korea. The investigators plan to register available cases from those who are available to agree to give written informed consent and provide their blood samples to participate in this study prospectively, according to the inclusion and exclusion criteria.
This study investigates hepatitis C virus (HCV) outbreak in South West general population in Burkina Faso with three specific objectives: estimate HCV prevalence in South West Region general population in 2019; identify factors associated with recent HCV infection (in subjects younger than 20 years); and evaluate the pilot treatment strategy implemented by the national program for diagnosed cases during investigation.
