[Cholestatic hepatitis during treatment with I.N.H. and rifampicin: arguments in favour of the hepatotoxicity of rifampicin (author's transl)].

It is generally accepted that hepatitis occurring during treatment with INH and rifampicine results from the hepatotoxicity of INH metabolites. A case is reported of cholestatic hepatitis occurring during such treatment, in which there was a previous history of an isolated hepatic affection. The administration of INH and rifampicin caused cholestasis alone, which reoccurred after rifampicin administration only. No immuno-allergic phenomenon has been shown to be involved in rifampicin toxicity. This observation suggests that rifampicin may be hepatotoxic itself, especially in patients with previous hepatic affections.
