Although treatment with plasma exchange increased the survival of patients with thrombotic thrombocytopenia purpura to 80% in the 1980s, no further increase of survival occurred over the next 20 years. However, more consistent use of adjuvant treatment with corticosteroids and rituximab in recent years has begun to further increase survival as well as decrease the frequency of relapse.
With adjuvant treatment, durable remissions can be achieved more quickly, requiring fewer days of plasma exchange.
Fewer days of plasma exchange have resulted in fewer complications, such as central venous catheter-related systemic infections.
Future potential options for adjuvant treatment, recombinant ADAMTS13 to correct severe ADAMTS13 deficiency, and agents to block von Willebrand factor-mediated platelet thrombosis are being investigated.
