RESUMEN
With increasing travel to tropical area, the number of patients with imported malaria in this country is increasing. RBC exchange transfusion has proposed as a adjunct therapy for very severe falciparum malaria to reduce the parasite load rapidly. We report a patient with severe Plasmodium falciparum infection with 26% of erythrocyte parasitized, treated with RBC exchange transfusion in addition to conventional chemotherapy. The exchange of 1200 mL of red blood cells was carried out with 7 packed red cells using automatic cell separator. This patients recovered from his disease despite respiratory distress syndrome and acute renal failure. We conclude that RBC exchange is a useful adjunct to conventional chemotherapy and should be considered in patients with severe and complicated falciparum malaria.
