  Purpose
One single study has suggested that bone mineral density (BMD) is reduced in patients with non-cirrhotic chronic viral hepatitis C. Antiviral combination therapy with standard interferon and ribavirin may further decrease BMD. The aim of this study is to systematically investigate the effect of chronic hepatitis C genotype 1 infection alone and current standard therapy with peginterferon alfa-2a/ribavirin on BMD and bone metabolism.

Condition Intervention Phase
Hepatitis C, Chronic Liver Diseases Virus Diseases Drug: peginterferon alfa-2a and ribavirin Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Non-randomized Prospective Study on the Effect of Antiviral Therapy With Peginterferon Alfa-2a and Ribavirin on Bone Mineral Density and Metabolism in Patients With Chronic Viral Hepatitis C Genotype 1

Primary Outcome Measures:
  • Change of the bone mineral density of the lumbar spine and right hip measured by DEXA in patients with chronic hepatitis C with or without antiviral combination treatment with peginterferon and ribavirin [ Time Frame: 96 weeks ]

Secondary Outcome Measures:
  • Change in markers of bone formation and resorption over time during antiviral therapy and after cessation of therapy. [ Time Frame: 96 weeks ]
