Severe ticlopidine-induced cholestatic syndrome.

A patient with chronic renal insufficiency undergoing dialysis treatment presented with a clinical picture of acute intrahepatic cholestasis and alterations in liver function indices. Liver biopsy showed a histological picture of hepatitis with cholestatic signs. A causal correlation with the recent administration of ticlopidine was hypothesized, which led to the drug being discontinued. Four months after drug withdrawal no improvement in the biochemical parameters had yet occurred and the patient's clinical conditions were indeed worsening so we proceeded with extracorporeal selective plasmapheresis treatments to reduce the bilirubin. As the cholestatic syndrome was unresolved and owing to the progressive worsening in the clinical picture, the patient was submitted to combined liver and kidney transplant followed by a rapid functional recovery in both organs. Regular monitoring of the hepatic function indices during the therapy with ticlopidine is therefore indispensable for the early detection of unpredictably severe hepatotoxicity. 2007 S.
