Clopidogrel-induced thrombotic thrombocytopenic purpura: a case report

Abstract

Thrombotic thrombocytopenic purpura (TTP) is a rare variant of thrombotic microangiopathy. We report a case of TTP in a Nigerian chronic kidney disease (CKD) patient who was previously on clopidogrel. The features of TTP resolved soon after clopidogrel was withdrawn. Clopidogrel is a cardio-protective anti-platelet drug used in CKD patients at risk of dyspepsia. However, its potential to cause TTP should be recognized and considered in acute kidney injury (AKI) patients previously on clopidogrel.
