Evans' syndrome: possible benefit from plasma exchange.
Because of previous reports of benefit of plasma exchange in immunologic disorders, we plasmapheresed a 45-year-old woman with immune thrombocytopenia and autoimmune hemolytic anemia (Evans' syndrome) who appeared to be dying despite splenectomy, prednisone, immunosuppressives and transfusions. Nine liters of plasma were removed over a 12-day period. Prior to plasma exchange, the patient's hematocrit remained below 16 per cent despite six units of red blood cells over a three-day period. Following plasma exchange, the hematocrit rose to 29 per cent; the platelet count gradually rose from 14,500/microliter to 272,000/microliter; and the transfusion requirements declined to only two units of red blood cells over the next 37 days. We conclude that plasmapheresis should be considered in the management of patients with refractory immune thrombocytopenia and autoimmune hemolytic anemia.
