Abstract

This report describes objective improvement in two patients with poorly responsive thrombotic thrombocytopenic purpura (TTP) syndromes (with cryosupernatant). The first had a partial response to plasma exchange with whole plasma (fresh frozen plasma; FFP) and responded dramatically when switched to plasma exchange with cryosupernatant replacement. The second had chronic TTP (three relapses in 9 months) that required prolonged courses of exchange with FFP (∼ 1 month each) to achieve remission. Attempts to manage her recurrent TTP with infusion of two units of FFP had been unsuccessful. The latter patient was tried on cryosupernatant infusions (2 units daily) and responded within 4 days. Moreover, she has been in continuous remission for 12 months while receiving 2 units (one to three times per week). These results suggest that cryoprecipitate‐poor plasma may offer advantages over whole plasma in the management of both acute and chronic forms of TTP. Β© 1993 Wiley‐Liss, Inc.
