Change of Glucose Metabolism and Fibrosis Markers in Patients With Hepatitis C Under Treatment With Antiviral Agents

Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. It is well known that metabolic factors play an important role in fibrosis progression and steatohepatitis for example in non-alcoholic steatohepatitis (NASH). Accordingly changes in glucose metabolism in patients with chronic hepatitis C might directly impact disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis. Follow-up examinations will determine the long-term metabolic changes of successful elimination of the virus by antiviral treatment.
