Active clinical trials for "Hepatitis, Chronic"

A phase 2a clinical Study of Hepalatide for Injection in Subjects with Chronic Hepatitis D

The investigators' research is aimed at developing more effective, finite approaches for managing individual patients with chronic hepatitis B (CHB). This prospective clinical and basic scientific study exclusively focuses on patients with the early antigen negative form of disease, which in developed countries is treated indefinitely with antiviral drugs. The investigators' study "BeNEG-DO," directly offers patients who are already taking standard oral Hepatitis B Virus (HBV) antiviral therapy for at least 192 weeks the option to stop or continue treatment. Drawing on data from pilot studies, including the investigators' own University of California, San Francisco and Sutter Institutional Review Board-approved study, the investigators will examine a finite HBV treatment strategy on clinical outcome and safety. In conjunction, the investigators will study immunologic mechanisms and gene expression profiles that correlate with and predict the post-treatment clinical course. The BeNEG-DO study could seriously question, and potentially change, the current treatment paradigm for millions of patients with CHB and also lead to new disease-terminating antiviral therapeutics.

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.

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.

This study is aimed to collect and analyze clinical data of patients with chronic viral hepatitis in the real world, to investigate the long-term outcome of these patients and to optimize treatment options based on these data.

Chronic hepatic disease, and especially cirrhosis, are associated to a global dysfunction of the immune system. Liver transplantation represents the only replacement therapy for end-stage liver disease and a curative means of localized hepatocellular carcinoma (HCC) but required immunosuppressive treatment to limit the risk of rejection. Candidates for liver transplantation are at an increased risk for severe infections, some of which can be prevented by vaccination. With regard to vaccine preventable diseases, these patients share the same pitfalls than all immunocompromised individuals: i) a theoretical or proven increased incidence and severity of certain infections warranting specific vaccine recommendations; ii) a decrease in immunogenicity of vaccine; iii) a risk of developing vaccine disease after administration of live attenuated vaccines. It is therefore recommended for all patients awaiting liver transplantation: i) updating the vaccinations recommended in general population (DTPw, MMR); ii) vaccination against viral hepatitis A and B to limit the risk of severe hepatitis; iii) vaccination against pneumococcal infection, influenza and chickenpox more common and more serious in this population. However, these recommendations are based on theoretical assessments and experts opinions; i) immunogenicity of vaccination in cirrhotic patients and persistence of post-transplant protection had been poorly assessed as well as their determinants; ii) there are only a few data regarding the tolerance of vaccinations in this population; iii) vaccination coverage of patients with end-stage liver disease is poorly known in France and; iv) the perception and acceptability of vaccinations have not been evaluated in this population. Investigators hypothesis is that: the vaccination schedule currently recommended for liver transplantation does not provide adequate protection against vaccine targets 6 months after liver transplantation.

Follow up of Chronic hepatitis C Patients with moderate to severe fibrosis and cirrhosis treated with Direct Acting Antivirals after Sustained Virological Response for 4-5 years to detect changes in hepatic fibrosis and liver functions.

This is a multi-centre prospective longitudinal cohort study with the aim of collecting and storing clinical data, patient blood, DNA and PBMCs to examine outcomes related to drug resistance, drug monitoring and host genetics in the era of directly acting antiviral drugs for hepatitis C therapy.
