[Cholestatic liver disease and thrombocytopenia associated with long exposure to ticlopidine].
A 45-year-old woman was admitted to the hospital because of cholestatic liver disease and severe thrombocytopenia following a 4-day history of fever and malaise. In her childhood the patient suffered from acute rheumatic fever with secondary mitral stenosis. Three years before admission, an atrial fibrillation had been diagnosed for which the patient was put on ticlopidine, 250 mg daily, that was taken regularly, without any adverse event. The patient had no history of cholestatic hepatitis or biliary colic. The abdominal ultrasonography was negative for biliary tract diseases and histological features were compatible with drug induced hepatotoxicity. Laboratory tests for viral and bacterial infection were negative. No other medications, apart from 2 doses of nimesulide, had been taken by the patient in the previous days. Ticlopidine was discontinued on admission and both bilirubin and platelet count rapidly normalized. We think that, in our patient, ticlopidine may be responsible of concomitant hematologic and hepatic toxicity and the trigger event might have been the reduced renal excretion of the drug following acute renal failure.
