Acute hepatitis E is caused by infection with hepatitis E virus, which is endemic in developing countries. Recently, the number of cases with acute hepatitis E is increasing in Japan due to increased travel to the endemic areas. This paper reports a case of a Japanese man with acute hepatitis E who had a history of traveling to south China. Serum creatine phosphokinase was elevated on admission without symptoms of muscle damage (isoenzyme MM 100%), and normalized in parallel with resolution of hepatitis, raising the possibility of an association between elevation of creatine phosphokinase and acute hepatitis E. However, we need to investigate further the incidence of elevation of serum creatine phosphokinase in many cases with acute viral hepatitis including hepatitis A, B, and C to determine whether muscle disorder is characteristic of acute hepatitis E.
