Active clinical trials for "Hepatitis A"

The study aims to investigate possible associations between ongoing viral hepatitis (i.e. hepatitis A, B, C or E virus infection) and ultrasound or computed tomography-verified gallstone disease.

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.

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

The present research aims to collect virological and clinical data on hepatitis E virus (HEV) infections, either in acute or chronic forms of HEV infection in North-Eastern France, with liver- or non liver-related symptoms, plus data on HEV circulation in the outside environment. The purpose of this study is to improve the diagnosis and care of HEV-infected patients, as well as the preventive features to take into account in order to avoid food- and environment-borne infections. At last, we will investigate HEV molecular characteristics, with the hypothesis that some advantageous HEV strains coul be more pathogenic for some tissues and/or organs.

The purpose of this study is to study the role of the Immune System in causing arthritis in patients with Hepatitis C.

The aim of the study is to investigate the epidemiology, natural history and treatment outcomes of acute hepatitis C (HCV) infection. Given the current pattern of case reporting, the cohort will be largely made up of human immunodeficiency virus (HIV)-positive patients, but HIV-negative patients with acute hepatitis C (AHC) will also be enrolled to enable comparisons to be made as appropriate and possible.

This is a multi-center cross-sectional study in which the Real-time Tissue Elastography® measurements will be collected prospectively from patients with chronic hepatitis B or C virus presenting for liver biopsy.

Primary objective: Evaluate the prevalence of personality disorders in patients starting treatment for hepatitis C in the prison and determine their influence on the evolution of the disease.

Previous studies dealt with patients who maintained antiviral drugs for 2 ~ 6 months after final chemotherapy and they revealed that many of the patients who stopped preemptive antiviral drug within 6 months experienced viral reactivation. Based on the study results, guidelines recommend that preemptive antiviral therapy should be maintained for at least 6 months. Nevertheless, many clinicians apply the preemptive antiviral drugs for 1~2 years or longer after final chemotherapy without definite evidences, and this practice increases the medical expenditure a lot. Therefore, the investigators are going to find out the proper and safe duration of preemptive antiviral therapy which can be a good reference in the future practice.

Chronic hepatitis B (CHB) is a serious liver disease worldwide, and the leading cause of cirrhosis and hepatocellular carcinoma (HCC). HBsAg loss/seroconversion is considered to be the ideal endpoint of antiviral therapy in both HBeAg-positive and -negative patients, and the ultimate treatment goal in CHB, However HBsAg loss occurred rarely by interferon treatment. Although It was reported that in nature history HBsAg level≤100 IU/ml can bring good long term outcomes in patients with chronic hepatitis B. it was not clear whether patients who achieved HBsAg level≤100 IU/ml by interferon treatment could maintain sustained viral response and the state of HBsAg level≤100 IU/ml.
