Active clinical trials for "Hepatitis"

Liver fibrosis is an important public health problem, with a substantial morbidity and mortality due to progression to cirrhosis and hepatocellular carcinoma. All causes of chronic liver disease may lead to fibrosis. The traditional diagnostic approach requires a biopsy for assessing the severity of liver disease prior to therapy. However, liver biopsy has several limitations: cost, sampling error, and procedure-related morbidity and mortality. Considering the high prevalence of viral hepatitis and nonalcoholic fatty liver disease, a condition often associated with obesity and type 2 diabetes, there is an urgent need for noninvasive screening, diagnosis and monitoring strategies of chronic liver disease severity. Our team has the expertise to investigate ultrasound-based and magnetic resonance-based elastographic methods for the noninvasive staging of liver fibrosis. The primary objective of this cross-sectional study is to compare the sensitivity of elastographic methods for detecting histology-determined significant fibrosis. The secondary objectives are to compare the diagnostic accuracy of these elastographic methods and the influence of potential confounders (inflammation, steatosis and iron deposition) on their diagnostic accuracy.

The major goal of this project is to identify the role of the immune responses in the emergence of protease inhibitor mutants during therapy.

The purpose of this research study is to explore what role immune cells within the gut (the sigmoid colon) have locally and on the immune system of patients infected with HCV, HIV or HCV/ HIV co-infection.

An exploratory clinical trial to evaluate the pharmacokinetic characteristics of I.V. Hepabig injection used for prevention of hepatitis B relapse after liver transplantation.

This non-interventional clinical study will be conducted to prospectively collect serial plasma samples from subjects with chronic HBV infection who are initiating antiviral therapy. These samples will be used to estimate clinical utility endpoints for the Aptima HBV Quant assay, which is used as an aid in the management of HBV-infected patients undergoing HBV antiviral therapy.

Antiviral prophylaxis can prevent the risk of biologic agents-associated HBV reactivation in hepatitis B inactive carriers and patients with past HBV infection

This observational study will assess predictors of early on-treatment and sustained virological response in treatment-naïve patients with chronic hepatitis C initiated on treatment with Pegasys (peginterferon alfa-2a) and ribavirin. Data will be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <5000.

Transcatheter arterial chemoembolization (TACE) is the traditional method for the palliative management of patients with hepatocellular carcinoma (HCC). Few previous studies had demonstrated that the serum level of anticancer drug from patients treated by TACE was similar to those treated by systemic chemotherapy. Since systemic chemotherapy may have the possibility to influence patient's general defense ability, hepatitis B virus may reactivate after chemotherapy.This study is to investigate the possibility of TACE in the reactivation of hepatitis B virus.

We propose a largely retrospective study with short-term prospective follow-up in a subgroup of patients who have not yet been treated with 48 weeks of entecavir following partial response to adefovir. The aim of the study is to describe sequential virologic response to adefovir and entecavir.

The goal of this study is to elucidate the reasons why patients with chronic hepatitis C (CHC) would not be considered eligible for antiviral treatment. The study is conducted in common clinical practice at approximately 54 sites in Italy. Patients deemed eligible for antiviral therapy will be treated at the discretion of the physician with either peginterferon alfa-2a or peginterferon alfa-2b, both in combination with ribavirin, in accordance with approved labeling. A secondary objective of this study is to define "treatment failure" and to evaluate the reasons for treatment discontinuation.
