Erythrocytapheresis for Plasmodium falciparum infection complicated by cerebral malaria and hyperparasitemia.
In malaria due to Plasmodium falciparum, life-threatening complications are in part related to the degree of parasitemia. Whole blood exchange and red blood cell exchange (RCE) have been used for the rapid removal of parasites from the circulation of patients with a high parasite load complicated by cerebral, pulmonary, and renal dysfunction. We have treated three 5-45-year-old patients with hyperparasitemia and end-organ dysfunction with red cell exchange by automated apheresis as an adjunct to specific anti-malarial chemotherapy. Parasitemia dropped more than 80% in all three patients immediately after the exchange, and all patients had an uneventful and full recovery. In combination with effective anti-malarial chemotherapy, apheresis RCE is a safe and rapid approach to treat complicated malaria due to P. falciparum.
