Therapeutic plasma exchange in patients with grade 2-3 hematopoietic stem cell transplantation-associated thrombotic thrombocytopenic purpura: a ten-year experience.
In the present retrospective study we report our 10-year experience with therapeutic plasma exchange (TPE) in 18 patients with grade 2-3 hematopoietic stem cell transplantation (HSCT)-associated thrombotic thrombocytopenic purpura (TTP). During TPE a mean total quantity of 26.5 +/- 15.1 L of plasma was exchanged. Five patients (27.7%) had a complete response eight patients (44.4%) had a partial response while five patients (27.7%) died during TPE treatment. Among the survivors, relapse of TTP occured in three patients (23%) and although these patients were treated again with TPE, all died. First-year survival rate was 41.2%. Our results indicate that TPE may be effective in the treatment of some patients with grade 2-3 HSCT-associated TTP.
