We report a case study of a patient with cholestatic hepatitis undergo
ing treatment with oral ticlopidine. The patient was admitted to our h
ospital for a transient ischemic attack, and after 40 days of ticlopid
ine therapy developed cholestatic jaundice, fever, itching, and arthra
lgias. Results from an ultrasound, computed tomography scan, and endos
copic retrograde cholangiopancreatography eliminated the presence of b
iliary obstruction; results from a liver biopsy showed a histopatholog
ic picture consistent with drug-induced cholestatic hepatitis. One yea
r after discontinuation of ticlopidine, the patient was still asymptom
atic, but laboratory data showed relevant abnormalities, indicating pe
rsistence of cholestasis and hepatic injury. This is the first reporte
d instance of a patient with cholestatic hepatitis that developed duri
ng treatment with ticlopidine and persisted despite interruption of dr
ug administration.
