Active clinical trials for "Hepatitis"

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.

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).

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.

The rapidly progression of the disease in HIV-HCV co-infected patients justify the treatment. Combination of Peg interferon and Ribavirin is the best treatment because it improve the compliance of treatment. In APRICOT study genotypes 2 and 3 patients received 48 weeks and the rates of end of treatment response was 64% and the sustained virological response (24 weeks after the end of treatment) 62%. In mono-infected patients trials showed there are not differences in the sustained virological response between 24 and 48 weeks of treatment, however exit the doubt concerning the different kinetic viral in HIV-HCV co-infected patients and this could be related with a lost of profit with a shorter duration of treatment, only 24 weeks. In this study we woud like to evaluate if 24 weeks of treatment in HIV-HCV co-infected patients genotype 2 or 3 will have the same rate of clearance of virus at the end of follow-up period.

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)

The present study will explore the immunogenicity of AVAXIM™ 80U-Pediatric in 12-13 months Turkish children and check if the administration of the MMR trivalent vaccine on the same day but at different site will interfere on immunogenicity for the four valences Hepatitis A, Measles, Mumps, and Rubella.

This study will assess the repeatability of Magnetic Resonance Elastography (MRE) in both healthy volunteers and Hepatitis C Virus (HCV)-infected patients with fibrosis and lay the groundwork for the validation of MRE as an alternative to liver biopsy.

Little is known about the nature and extent of the disturbance in hepatic function and biliary hepatic clearance in chronic viral hepatitis, while the course of this disease, the functional implications and response to treatment are difficult to predict. This study aims to assess this in patients with chronic viral hepatitis B (CHB) and chronic viral hepatitis C (CHC) who are eligible for treatment in accordance with the established consensus guidelines in the involved countries. The pharmacokinetics of NRL972 will be determined at baseline (within one month of starting treatment), at 3-monthly intervals during treatment, for up to 12 months (or at the end of treatment), and at 3 and 6 months after the end on treatment. This will provide a clearer understanding regarding the use of the pharmacokinetics of NRL972 in detecting changes in biliary clearance during and after treatment for CHB and CHC.

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.
