Filter by:Autoimmune hepatitis (AIH) is a progressive inflammatory liver disorder of unknown etiology. If left untreated, it progresses to liver cirrhosis and liver failure. Diagnosis of AIH relies on the exclusion of other causes of liver disease and the presence of positive clinical, biochemical, and histological criteria. AIH has a very wide spectrum of clinical presentations ranging from being asymptomatic to an acute severe fulminant disease. It may be associated with other autoimmune disorders such as thyroiditis, type 1 diabetes, vitiligo, inflammatory bowel disease, or juvenile idiopathic arthritis. Biochemical features of AIH include elevation of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and immunoglobulin G (IgG) in addition to autoantibodies. Liver biopsy is recommended in any patient with suspected autoimmune hepatitis where interface hepatitis is the hallmark of the disease. Immunosuppression is the mainstay of therapy in AIH. Prednisone is administered as the initial therapy either alone or in combination with azathioprine. Liver transplantation is indicated in patients who develop fulminant hepatic failure that is unresponsive to corticosteroids and in patients who develop end-stage liver disease.
A project to understand the determinants of health behaviour among those with chronic hepatitis D virus (HDV) infection, under the care of the viral hepatitis service at Kings College Hospital (KCH). This is to improve and implement pathways and patient information distribution to improve access to care in an ethnically diverse population living with HDV in the UK. Kings college hospital NHS Foundation Trust is uniquely placed and serves a large diverse population from areas such as pan pacific Asia, Eastern Europe and regions in Africa, where English is not their first language. This diversity is also seen in other London Hospitals but less so in other parts of the UK.
This is a retrospective, non-interventional study. Investigators from infectious diseases and gastroenterology departments will participate this study. Patients data will be collected from hospital medical records.
Enroll patients who are pre-treated with Entecavir at least 24 weeks and confirmed HBV antiviral (HBV DNA <69 IU/mL) effects. Subjects are given one test drug or comparator once a day for 48 weeks according to the results of random assignments, and their HBV antiviral inhibitory effect and safety are evaluated at 24 and 48 weeks visits.
Some patients with low-level viremia (LLV) are also likely to develop hepatocellular carcinoma (HCC) or other liver diseases. The relationship between HBV RNA levels and fibrosis in patients with HBV DNA negative or LLV is still lacking evidence. The purpose of this study is to observe the differences in HBV RNA levels and their association with efficacy in HBV DNA negative or LLV patients. Investigators conduct the prospective, single-center, non-randomized, observational clinical study. A total of 100 chronic hepatitis B (CHB) patients who receive antiviral therapy with nucleoside (acid) analogues for 1-3 years will be enrolled. The enrolled patients will be followed up five times to collect clinical data and record adverse events (at baseline, week 12, week 24, week 36 and week 48, respectively).
Evaluate the potential of ART combined with interferon therapy to achieve functional cure of hepatitis B in HIV/HBV co-infected patients
The goal of this observational study is to prospectively follow chronic hepatitis B patients who had HBsAg decline in the past 12 months prior to screening. The main question it aims to answer are: - Describe treatment pattern and its impact on HBsAg loss in hepatitis B patients who had HBsAg decline in past 12 months due to any reason (with or without new molecular entities therapy). Participants will be followed up for 36 months after enrollment and may be extended upon expiration according to study objectives.
This test-negative study is designed to evaluate the long-term effectiveness of hepatitis E vaccine (Hecolin®) and to explore the prevalence of rat hepatitis E in Dongtai City.
Spontaneous, pharmacological observational, no-profit, retrospective, multi-center. This study was designed to get a "real-life" snapshot across several Italian Hepatology centers. All HDV patients are followed up according to EASL 2017 guidelines. This allows uniformity on the indication for antiviral treatment and management of that antiviral therapy. No off-label medications are used. All data are retrievable from the patient's medical record. In addition, clinical and biochemical data from patients at month 0, 1, 2, 4, 6 and 12 of treatment, and otherwise within the study period, will be collected retrospectively/longitudinally. The primary objective of the study is to describe the virological response to BLV in all patients starting BLV therapy, defined as a >2 Log decline in HDV-RNA or undetectable HDV-RNA (using the Robogene 2.0 quantitative kit, LLQ <6 IU/ml) at month 12 of therapy. All patients with active HDV chronic hepatopathy (quantifiable HDV-RNA) who initiated treatment with BLV 2 mg/day during the study period at the S.C. Gastroenterology and Hepatology (Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico) and at participating centers, and who met the inclusion criteria and none of the exclusion criteria.
This study is a multi-center, double-blind, active-controlled, randomized, parallel clinical study to evaluate the efficacy and safety of DA-2803 in chronic hepatitis B subjects
