RT Journal Article SR Electronic T1 Methylprednisolone-induced hepatotoxicity in a 16-year-old girl with multiple sclerosis JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e226687 DO 10.1136/bcr-2018-226687 VO 11 IS 1 A1 Eleonora Rotondo A1 Alessandro Graziosi A1 Vincenzo Di Stefano A1 Angelika Anna Mohn YR 2018 UL http://casereports.bmj.com/content/11/1/e226687.abstract AB Multiple sclerosis (MS) is a chronic inflammatory disease with demyelination of the central nervous system. High-dosage corticosteroids are the first-line therapy in the acute relapsing of MS. We report a case of severe high-dose methylprednisolone-induced acute hepatitis in a patient with a new diagnosis of MS. A 16-year-old girl was admitted for urticaria, angioedema, nausea and vomiting a month later she had been diagnosed with MS and treated with high-dosage methylprednisolone. Laboratory investigations showed hepatic insufficiency with grossly elevated liver enzymes. A liver biopsy showed focal centrilobular hepatocyte necrosis with interface hepatitis. Methylprednisolone-induced hepatotoxicity can confuse the clinical picture of patients with MS and complicate the differential diagnosis. We believe that each specialist should know it and monitor patients with MS taking high doses of methylprednisolone. As there is no screening model that predicts idiosyncratic hepatotoxicity, we promote screening for potential liver injury following pulse steroid therapy.
