[Acute renal insufficiency caused by rifampicin].

A case of acute renal insufficiency associated with acute hepatitis that arose in the course of intermittent rifampicine management is reported. Specific reagin-type antibodies were noted in the circulating blood. The clinical, morphological and pathogenetic aspects of the case are compared with those of kidney disease caused by penicillin. While certain clinical features appear in both situations, the histological and immunofluorescence data suggest that two separate pathological entities are involved.
