title: [Granulomatous hepatitis caused by nomifensine].
abstract: Four patients are described who developed granulomatous hepatitis 4-6 weeks after treatment with nomifensin. The granulomas were located both in the portal tract and the liver parenchyma, and contained eosinophils and a few polynuclear giant cells. Serum alkaline phosphatase, alanine aminotransferase and bilirubin were raised in three, two and one patient respectively. After medication was discontinued all abnormalities disappeared within 6-10 weeks. After oral intake of 25-50 mg nomifensin all patients experienced paroxysms of high body temperature for several hours. Reexposure in one patient resulted in another fever spike 6 hours after ingestion. No other cause of the fever or the granulomatous hepatitis was identifiable. The clinical data, especially the simultanous occurrence of drug fever and the histologic pattern, are compatible with an allergic mechanism of the liver granulomas. In the presence of high fever and abnormal liver tests in relation to nomifensin treatment, an allergic drug reaction should be considered.
