Patient description: The patient is a 55-year-old man diagnosed with HCV 2 years ago and the recent coinfection with HBV. His past medical history is non-significant. He is on IFN, RBV and direct antiviral drugs for the past 6 months. The patient takes no other medications. His medical records show previous positive HCV RNA tests and a positive enzyme immunoassay for anti-HCV-antibodies. The recent biopsy was negative for hepatocellular carcinoma and was only remarkable for chronic inflammation compatible with a chronic viral hepatitis. There is no evidence of alcoholic liver disease, bleeding from esophageal varices, hemochromatosis, autoimmune hepatitis, or metabolic liver disease. He is an alert male with no acute distress. His BP: 130/75, HR: 90/min and BMI: 27. His abdomen is soft with no ascites or tenderness. The lower extremities are normal with no edema.
