Active clinical trials for "Hepatitis B"

The treatment of choice for chronic hepatitis D is uncertain. The investigators hypothesize that pegylated interferon (IFN) alfa-2b in combination with ribavirin (RBV) may be effective in the treatment of chronic hepatitis D patients who are also infected by hepatitis B virus (HBV). The purpose of this study is to test this hypothesis. The investigators will use pegylated IFN alfa-2b in combination with RBV for the treatment of patients with dual chronic hepatitis D virus (HDV) and HBV infection. A 24-week course of combination therapy pegylated IFN+RBV will be used.

The aim of this study is to examine the result of seroprotection using the accelerated vaccination schedule in vaccination of hemodialysis patient through using combined hepatitis A and B vaccine.

This study evaluates whether Peg-IFN alfa-2a can reduce the recurrence rate of hepatitis B in 96 weeks after nucleoside analogue (NUC) withdrawal. The HBV HBeAg-Negative patients who received NUC anti-virus treatment for 2.5 years and reached stopping rule in 《Chinese chronic hepatitis B prevention and treatment guidelines》(2010) were randomly assigned into three groups: One group discontinue the NUC treatment and follow up for 96 weeks,One discontinue the NUC treatment ,receive Peg-IFN alfa-2a 180 μg by week for 24 weeks and follow up for 72 weeks,The other discontinue the NUC treatment ,receive Peg-IFN alfa-2a 180 μg by week for 48 weeks and follow up for 48 weeks.

Hepatocellular carcinoma (HCC) is a very severe disease in Taiwan caused 7,000 deaths per year, and majorly about 70% is caused by the chronic hepatitis B virus infection. A repeat, long-term, and severe chronic hepatitis would be more possible progressed into liver cirrhosis and HCC. As previous records, there might be 2% of chronic HBV patient would progress to liver cirrhosis, and 5% of the liver cirrhosis's patients would develop to HCC. In some cases, the HBV patient also might directly develop to HCC without liver cirrhosis phase.

To assess the prevalence of blood-borne viral infections in prisons in Belgium, screening will be executed in several prisons in Flanders, Brussels and Wallonia to obtain a geographical representative distribution. Upon informed consent screening will be performed using whole capillary blood (finger prick testing) with three different tests for HCV Ab, HBsAg and HIV. Screening will be performed first. While awaiting the test result (15-20min), the participant can fill out a questionnaire (together with the study nurse), concerning risk factors for HCV, HBV and HIV infection. This questionnaire is filled out directly online, and will be immediately implemented in the encoded database. The database is set-up according to the rules of good clinical practice. (Castor EDC software). The results will be filled out immediately by the prison staff in this database after it is filled out by the participant, minimizing the risk of displacement of test results.

The purpose of this study is to demonstrate the durability of protection against hepatitis B virus (HBV) infection approximately 8-9 years after vaccination with Vaxelis®. This is an estimation study, and no formal hypothesis testing was performed.

This is a study to show that vaccination with three doses of Quinvaxem presented in Uniject is not inferior to vaccination with three doses of Quinvaxem presented in single dose vials, with respect to protection against all antibodies (anti-hepatitis B surface antibodies, anti-polyribosyl ribitol phosphate (PRP), anti-diphtheria, anti-tetanus and anti-Bordetella pertussis) one (1) month after completion of the 6-10-14 week vaccination course.

For HBeAg (+) hepatitis B patients who have been treated by entecavir for 48 weeks but without HBeAg loss, switching to peg-interferon may increase the response rate. In the investigators study, patients were divided into two groups. In Group A, patients continued entecavir for another 72 weeks. In Group B, patients switched to peg-interferon-2a monotherapy for 48 weeks, then followed up 24 weeks.

This is a pilot, monocentric, prospective, randomized control trial looking at the use of rapid tests as a part of normal care. The investigators will be testing for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Testing will be proposed to all persons seeking care at the Centre d'Accueil, de Soins et d'Orientation from the organization Médecin du Monde (CASO, MDM). Infection status of participants will be determined by either the standard test (ELISA) or rapid test. The choice between tests will be determined randomly. The overall goal is to determine the general acceptability and feasibility of rapid tests and to see if they can help individuals increase their awareness of infection status when compared to longer, routine methods of testing. In addition, results from these tests will allow the medical doctor to guide participants to appropriate care. All positive tests will be confirmed at a specialized hospital (Hôptial Saint-Antoine, Paris, France) and health-specific information will be obtained four months after testing.

The purpose of this study is to assess the loss of HbsAg after a 48-week pegylated interferon alpha 2a in patients with chronic hepatitis B (HBeAg negativation)
