Portal Pressure Predicts Outcome and Safety of Antiviral Therapy in Cirrhotic Patients With Hepatitis C Virus Infection

HVPG is an independent predictor of response to antiviral therapy, with better predictive value than liver stiffness, baseline HCV RNA levels, HCV genotype, or IL-28B polymorphism. The incidence and grade of thrombocytopenia during antiviral therapy are higher among patients with CSPH. In evaluating cirrhotic HCV patients for antiviral treatment, measurement of HVPG should be considered.
