This well-tolerated procedure is particularly useful in avoiding severe toxic reactions—in some cases fatal—occurring in patients with a high microfilarial load being treated with diethylcarbamazine.Similarly, automated erythrocyte exchange transfusion has proved effective in rapidly reducing high P falciparum blood load. Erythrocytapheresis combined with transfusion of packed red blood cells using a flow cell separator and specific chemotherapy should be strongly advocated in cases of malaria with either cerebral, renal, pulmonary, or hemostatic complications and parasitemia in excess of 10%.4-9Because apheresis may have a useful, and
