Abstract

In the present Japanese female patient with alanine aminotransferase (ALT) elevation greater than 500 IU/l during combination therapy with grazoprevir/elbasvir against HCV infection, this therapy was stopped at week 8. However, sustained virologic response was achieved. In the present report, we also focused on ALT elevation and sustained virologic response during and after antiviral therapies. The current case report demonstrates that careful monitoring of liver function tests may be required during direct-acting antiviral therapy against HCV infection because it is now possible to treat patients with polypharmacy, patients with chronic kidney disease, patients with cirrhosis or aged patients. Careful attention should be paid to liver damage as one of the adverse events in the use of HCV nonstructural protein 3/4A protease inhibitors. Of interest, many publications have addressed both ALT elevations during direct-acting antiviral therapy and viral clearance in relatively short treatment durations.
