She was admitted to our hospital for pegylated interferon ῌPeg-IFN῍ a2b plus ribavirin treatment for chronic hepatitis C. Her serum hepatitis C virus ῌHCV῍-RNA level became undetectable 3 weeks after the initiation of peg-IFN a2b plus ribavirin treatment. She su#ered from severe sore throat 8 weeks after the initiation of peg-IFN a2b plus ribavirin treatment. Despite symptomatic medications, sore throat continued. Peg-IFN a2b plus ribavirin treatment was discontinued because a causal relationship between sore throat and Peg-IFN a2b plus ribavirin treatment was suspected. Sore throat improved after discontinuation of Peg-IFN a2b plus ribavirin treatment. Although recurrence of hepatitis and viremia was predisposed because of premature discontinuation of the peg-IFN a2b plus ribavirin treatment, she has remained HCV-RNA negative, subsequently. 1 Division of Gastroenterology and Hepatology, Department of Internal Medicine, St. Marianna University School of Medicine, Kawasaki, Japan 2 Department of Pathology, St. Marianna University School of Medicine, Kawasaki, Japan 3 Division of Infectious Diseases, Department of Internal Medicine, University of Tokyo, Tokyo, Japan 4 Research Center for Liver Disease, Kiyokawa Medical Center, Tokyo, Japan 51
