Fig. 1. Changes in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin levels during hospitalization. Acyclovir was administered on the fourth day of hospitalization and intravenous immunoglobulin was administered on the fifth day of hospitalization. After the sixth day of hospitalization, AST and ALT levels began to decrease. Hepatitis A virus immunoglobulin G antibody and hepatitis A virus immunoglobulin M antibody were examined by radioimmunoassay. Hepatitis B surface antigen was examined by chemiluminescent microparticle immunoassay. Anti-hepatitis C virus and varicella zoster virus immunoglobulin M antibody were examined by enzyme-linked immunosorbent assay. Cytomegalovirus antigen was examined by monoclonal antibody stain. Polyomavirus examined by real-time polymerase chain reaction. Varicella zoster virus immunoglobulin G antibody was examined by chemiluminescent immunoassay.
