Adverse drug reaction to rifampin: a case with long lasting antiplatelet antibodies.

Rifampin is a drug able to induce adverse reactions involving both the kidney and the hematological system. We observed a case, throughly studied and we deemed worth-while to report it, for some important features that were evident. Transient hemolytic anemia, recoverable acute renal failure, persistent increased titer of anti-platelet antibody lasting also after 3 weeks from the withdrawal of the drug and in spite of corticosteroid therapy, could be explained by the immune mechanisms that are, therefore, postulated.
