Treatment of thrombotic thrombocytopenic purpura with plasma exchange, antiplatelet agents, corticosteroid, and plasma infusion: Mayo Clinic experience.
Ten patients with thrombocytopenia (TTP) were treated recently in our institution with plasma exchange (PE), steroids, and antiplatelet drugs. Additionally, fresh frozen plasma (FFP) was administered to nine patients, with folic acid given to eight patients. After 13 to 25 months of follow-up, we found that four patients achieved and remained in remission after initial treatment. Three patients had four relapses, which developed while they were taking antiplatelet therapy, and which were treated successfully with FFP alone, or with PE in addition to FFP. Four patients suffered major neurological or renal damage during their presentation or initial treatment. One of these patients died during his initial hospitalization. Another patient died 7 months after initial treatment. After analyzing this experience, we have concluded that antiplatelet drugs or corticosteroid should be used as the sole initial treatment most cautiously. The relative importance of the exchange process, per se, versus plasma infusion cannot be inferred from our observations, but plasma exchange with FFP appears to have had a real impact on recovery.
