Active clinical trials for "Hepatitis B"

Influence of antiviral treatment to the long term prognosis of patients with chronic HBV infection. The aim of antiviral treatment for HBV is to reduce the long term severe complications. In this study, the investigators divided patients with chronic HBV infection into two groups, which start early antiviral treatment and conventional antiviral treatment respectively. All the patients will be followed for ten years. From this study, the investigators want to find out the optimal time for patients with chronic HBV infection to start antiviral treatment.

Iron excess is increasingly regarded as an important cofactor in the morbidity attributed to many disorders. Assessment of body iron stores by measurement of serum ferritin concentrations has poor specificity and the most reliable method is histological or biochemical assessment from a liver biopsy. Because liver biopsy is an invasive procedure, imaging methods have been developed to detect and quantify hepatic iron content. The aim of the study is to use a simplified magnetic resonance imaging (MRI) technique to quantify simultaneously iron and fat contents in the liver and to compare the results to the quantification obtained biochemically.

The current extension study will assess the persistence of anti-HBs antibodies at Months 12, 24 and 36 after primary vaccination with Henogen's HBV vaccine or Fendrix™. This protocol posting deals with the objectives & outcome measures of the extension phase at Months 12, 24 and 36. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT00291941).

The primary purpose of this study is to demonstrate the lot-to-lot consistency of 3 production lots of GSK Biologicals' Hib-MenAC (Haemophilus influenzae type b and meningococcal serogroups A and C) vaccine when reconstituted with Tritanrix™-HepB (diphtheria, tetanus, pertussis, and hepatitis B) vaccine and administered as a single injection.

Hepatocellular carcinoma (HCC) is a common malignancy with poor prognosis worldwide. The asymptomatic of early-stage HCC may lead most patients diagnosed at advanced stages. This highlights the importance of HCC screening among high-risk populations to detect HCC at early stages and achieve better survival. Hepatitis B virus (HBV) infection is a major cause of HCC in China, but the utilization of HCC screening is suboptimal among patients with HBV infection. Currently, there are no-theory based intervention, to our knowledge, has been reported to improve HCC screening decision-making and uptake among patients with HBV infection . Therefore, based on our previous systematic review, the current study has proposed a nurse-led decision counseling program to improve decision-making and uptake of HCC screening among patients with HBV infection in mainland China. Participants in intervention group will receive nurse-led decision counseling. The intervention components include 40-minute education and tailored information regarding HCC screening. At the second week, decision support will be provided through 30-minute telephone call. At the third week, another telephone call (20 minutes) will be provided to help participants identify and address barriers to HCC screening. Participants in control group will receive usual care. After the intervention and at 3-month follow-up, the study will collect data related to HCC screening uptake rates. Findings are paramount to promote informed choice in HCC screening and early HCC detection to improve survival outcomes among patients with HBV infection.

As HBsAg clearance is uncommon in chronic hepatitis B (CHB) patients on nucleoside analogues (NAs) therapy. The purpose of this study is to optimize HBsAg clearance in CHB Patients with sequential treatment of pegylated interferon alpha and NAs.

There has been no report on whether the patients with gastric cancer who are also inactive Hepatitis B carriers should receive prophylactic use or preemptive Use of an Anti-viral Drug Entecavir. This open, randomized controlled clinical trial aims to compare the impact of the prophylactic use or preemptive use of an anti-viral drug Entecavir on the outcomes of patients with gastric cancer who are also inactive hepatitis B carriers during chemotherapy and the subsequent follow-ups.

Patients will receive Peginterferon alfa-2a according to the standard medical practice but the observation period is 12 weeks

The purpose of this long-term follow-up study was to evaluate the persistence of the cellular and the humoral immune response 4 years after the first dose of GSK Biologicals' investigational vaccine formulations containing HBsAg (used as a model antigen) and an adjuvant.

This study evaluates the Granulocyte colony-stimulating factor (G-CSF) in the treatment of Acute on Chronic Liver Failure in adult. Half participants will receive G-CSF and standard treatment in combination, while half participants will receive standard treatment.
