Simultaneously acute hepatitis B virus and C virus coinfection and subsequent chronic hepatitis C

Abstract

Hepatitis C virus (HCV) and hepatitis B virus (HBV) share similar transmission routes, but concurrent acute HCV and HBV infection was rarely reported. Little is known about viral interaction and hepatic biochemical features of acute HBV and HCV coinfection. We report an intravenous drug abuser with simultaneous acute HBV and HCV infections presenting as biphasic elevation of both alanine aminotransferase (ALT) and total bilirubin levels. HCV infection is the major cause of continuing hepatitis after termination of HBsAg antigenemia.
