History and admission findings: A 52-year-old man who had sustained a
cerebellar infarct was given the platelet inhibitor ticlopidine (2 x 2
50 mg/d) to prevent further thromboses. 28 days after starting the med
ication he complained of itchings, feeling unwell and diarrhoea. He ha
d also noted darkened urine and faecal discoloration, Physical examina
tion revealed marked jaundice and multiple scratch marks over the enti
re body. Investigations: The activities in serum of alkaline phosphata
se (420 U/I) and of gamma-GT (470 U/I) were markedly elevated and tota
l bilirubin concentration was maximally 26.4 mg/dl. Activities of GPT
(197 U/I) and GOT (44 U/I) were slightly increased. No cause was found
for any extra-or intrahepatic cholestasis with or without mechanical
obstruction (e. g. viral or autoimmune hepatitis). A biopsy, which sho
wed centro-acinar cholestasis also suggested drug-induced liver damage
. Treatment and course: Despite discontinuing ticlopidine, the signs o
f cholestatic hepatitis had only disappeared 2 1/2 months after the on
set of symptoms. Conclusion: Changes in the blood picture, allergic sk
in reactions and gastrointestinal disorders are among the significant
clinical side effects of ticlopidine. As this drug is increasingly bei
ng prescribed world-wide, the possibility of toxic liver damage should
be taken into account.
