A 74-year-old man with a history of transfusion at 35 years old in Egypt was referred to our hospital. He was infected with hepatitis C virus (HCV) genotype 4 (GT4), which is a rare HCV GT in Japan, and was also diagnosed with hepatic compensated cirrhosis. We safely treated the patient for 12 weeks with the combination of glecaprevir and pibrentasvir, and a sustained virologic response (SVR) was achieved. This is the first report of HCV GT4 infection in a treatment-naïve Japanese patient with cirrhosis in whom SVR was achieved with the combination treatment of glecaprevir and pibrentasvir.
