Active clinical trials for "Hepatitis B, Chronic"

The aim of this study is to determine the effect of the education given to patients with CHB who use oral antiviral drugs on oral antiviral drug use on drug compliance and quality of life.

Find a possible association between Fibronectin type Ⅲ domain containing protein 5 \ Irsin (FNDC5 rs3480) gene single nucleotide polymorphism with chronic hepatitis B and the distribution of its alleles, in relation to many clinical parameters of the chronic hepatitis B group. Asses the correlation between IL-35 serum level and the risk of chronic hepatitis B. Asses the correlation between SOD serum level and the risk of chronic hepatitis B.

This is a multicenter, prospective, real-world study, recruiting patients with chronic hepatitis B under anti-viral treatment. The recruited participants will receive peginterferon alpha based regimen or nucleos(t)ide alone. The primary objective of this study is to compare the long-term outcomes (including hepatocellular carcinoma, decompensated cirrhosis, etc）of different anti-viral therapies. The secondary objective of this study is to compare the serological response rates of different anti-viral therapies, evaluate the predictive value of HBV-related laboratory testings and describe the kinetics of them results during antiviral treatment. The follow-up time course of this study will be 5 years.

Hepatitis B virus (HBV) infection remains one of the most serious health problems worldwide. Patients with chronic HBV infection are at an increased risk for developing hepatic cirrhosis, hepatocellular carcinoma and even death. Although some predictive factors of the outcome of chronic HBV infection were identified, more precisely determine the factors which are associated with the outcome in non-selected patients with chronic HBV infection are still needed. The investigators purpose is to constitute a observational cohort of non-selected Chinese patients to create a database of epidemiological, clinical, biological, virological, immunologic and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.

All patients with chronic HBeAg negative hepatitis B treated with nucleos(t)ide analogues, who discontinue treatment based in the criteria outlined in the EASL hepatitis B guidelines shall be included in the present study. The aim is to evaluate the clinical outcome (virological relapse, HBsAg decline) and associated virological and immunological parameters.

Background: People who were born outside of the country are the largest group of adults infected with chronic hepatitis B virus (HBV) in the US. HBV affects the liver. If not treated, HBV infection can lead to serious liver disease, including cancer. One recent study showed that only 35% of foreign-born US adults were aware of their HBV infections. Foreign-born US adults may also have trouble getting proper care after they are diagnosed with HBV. In one small survey, language, cultural, and financial barriers were cited as the biggest reasons for not receiving care. To help more people with HBV, researchers want to learn how to find and overcome any barriers to care. Objective: This natural history study seeks to identify and better understand barriers that prevent foreign-born US adults from getting proper care for HBV infections. Eligibility: People aged 18 years and older with chronic HBV who were born outside of the US. Design: Participants will visit the NIH clinic 1 time. This visit will take about 20 minutes. Researchers will review participants medical records and collect information about their HBV. Participants will complete a survey. They will answer questions about: Where they came from. When they came to the US. How well they have adapted to living in the US. The health care they have received for HBV. Their age, gender, and education. Participants will be paid $10 for completing the survey. ...

Totals of 400 chronic hepatitis B or non-alcoholic fatty liver disease (NAFLD) patients with or without cirrhosis will be enrolled. Patients' clinical characteristics, including alanine aminotransferase, aspartic aminotransferase, total bilirubin, direct bilirubin, indirect bilirubin, triglyceride and total cholesterol, hepatitis B surface antigen, steatosis, and liver stiffness measurement will be collected. The consistence of liver fibrosis and steatosis assessment between Hepatus and FibroScan will be evaluated in this study.

Chronic hepatitis B (CHB) affects an estimated 292 million people, and causes approximately 800,000 people deaths per year from liver-related complications including cirrhosis and hepatocellular carcinoma, remaining a major global public health issue.Meanwhile, with the improvement of living standards and changes in lifestyle and dietary habits, non-alcoholic fatty liver disease (NAFLD) has become another important cause of liver cirrhosis and HCC.HBV combined with NAFLD inevitably develops into continuous or intermittent liver inflammation and fibrosis, which greatly increases the risk of cirrhosis, liver cancer and even end-stage liver disease. We aimed to investigate the risk factors and establish diagnostic models for hepatic inflammation, fibrosis in patients with CHB associated NAFLD. In addition, to find risk factors for liver cirrhosis, liver cancer or liver failure in patients with CHB-related NAFLD.

This is a two-way (retrospective and prospective) study of COVID-19 infection in an observational cohort of patients with chronic hepatitis B treated with antiviral therapy. Patients with chronic hepatitis B who received anti-HBV treatment in the Second Department of Hepatology, Beijing Ditan Hospital Affiliated to Capital Medical University from February 2022 to December 2023 were enrolled. After enrollment, demographic data of patients, information on antiviral treatment of chronic hepatitis B, COVID-19 vaccination, COVID-19 infection and COVID-19 incidence and treatment from January 2022 to pre enrollment, and data on HBV virus and serology, clinical biochemistry, liver and lung imaging, COVID-19 nucleic acid and COVID-19 antibody examination of patients were collected. After enrollment, prospective anti-HBV treatment, HBV virology, clinical biochemistry, liver imaging and COVID-19 infection and morbidity were observed. The patients with COVID-19 infection during the prospective observation period were observed for COVID-19 infection, onset and treatment, including body temperature, clinical symptoms, signs, cardiac examination, pulmonary imaging, COVID-19, clinical biochemistry, disease severity, time of virus negative conversion, hospital stay and outcome. The influence of COVID-19 infection on liver disease and the influence of interferon anti-HBV treatment on COVID-19 infection, its pathogenesis and prognosis were studied.

CR-HepB registry started in June 30,2012 to collect HBV cases from general hospitals or specialized hospitals for infectious diseases in mainland China. Demographics, diagnosis, laboratory test results, family history and prescriptions were recorded. The main criteria for registration is HBsAg-positivity more than 6 months, and these patients will receive followed-up visits every three to six months.
