Three weeks after the administration of intravenous methylprednisolone therapy, a 42-year-old female patient suffering from relapsing-remitting multiple sclerosis (RR-MS) presented with a profound elevation of liver transaminases (GOT 485 U/l, GPT 1082 U/l, glutamyl transpeptidase 170 U/l). Liver biopsy revealed a profound, still active hepatitis with portal lymphocytic infiltration and fibrosis. Most likely, existing acute hepatitis was of autoimmune origin and emerged from an immune rebound phenomenon after immunosuppressive therapy.
