Title: A study into the prevalence of diastolic dysfunction in cirrhosis

Sponsor: No

Brief summary: Cirrhotic cardiomyopathy is not a well recognized condition and the diagnostic criteria are not yet established. The aim of this study is to determine the prevalence of diastolic dysfunction (following the definition criteria provided in this study protocol) in patients with liver cirrhosis and to determine whether other factors (e.g. etiology, severity of liver dysfunction) affect the development of diastolic dysfunction in cirrhosis.

Study phase: Evaluation Study, Mulitcenter.

Titel: Optimization of treatment for patients with chronic hepatitis C infected with HCV-genotype 2 or 3: 12 vs. 24 weeks of treatment extension for patients without rapid virological response

Kategorie: A ("Hep-Net geprüft") & B ("Hep-Net gefördert")

Brief summary: Patienten mit einer chronischen Hepatitis C und HCV Genotyp 2 oder 3, die eine laufende PegInterferon alfa-2b/Ribavirin-Standardtherapie erhalten und ungünstige Therapievoraussetzungen haben (HCV-RNA > 15 IU/ml an Woche 4 der laufenden Therapie) werden entweder 24 Wochen (Gruppe A) oder 12 Wochen (Gruppe B) mit 1,5 Gg/kg/Woche PegInterferon alpha-2b und 800-1400 mg Ribavirin weiterbehandelt. Beide Gruppen werden nach dem jeweiligen Therapieende 24 Wochen nachbeobachtet. Die Aufteilung auf die 2 Behandlungsoptionen erfolgt per zentraler Randomisierung (1:1). Stratifiziert wird nach Geschlecht, Alter, Genotyp, Zirrhose sowie HCV-RNA Level > 600 000 IU/ml vor Beginn der Standardtherapie
