Does cyclophosphamide benefit relapsing thrombotic thrombocytopenic purpura?

Abstract

Thrombotic thrombocytopenic purpura (TTP) is a rare disease. A high index of suspicion is required for early diagnosis and treatment. It can present in acute as well as chronic forms. Cyclophosphamide has been reported to be beneficial in relapsing TTP. Herein a case of acute TTP evolving into relapsing phase of the disease is presented. Cyclophosphamide in our case achieved partial remission without the need for plasma exchange therapy. The rationale of cyclophosphamide in management of relapsing TTP is discussed.
