| Abstract: | A patient is described with cholestatic hepatitis following the use of carbimazole. A liver biopsy specimen showed intracanalicular cholestasis and some mononuclear cell infiltrate in the portal triades, consistent with drug toxicity; indications of an autoimmune or viral pathogenesis were absent. Rechallenge with the drug precipitated jaundice and disturbed liver function once more. Carbimazole induced a blastogenic response of patient lymphocytes in vitro. Both may suggest the involvement of an immune-mediated reaction, especially as it has been shown that sensitized lymphocytes may produce a cholestatic factor on stimulation with antigen. |
