title: [Treatment of fulminant falciparum malaria with erythrapheresis].
abstract: Ten days after his return from Cameroon, a twenty-six year old Frenchman, serving on voluntary service overseas, presented with fulminant falciparum malaria: shock, altered consciousness, haemolytic anaemia, threatening disseminated coagulation (platelets less than 150 X 10(-6).l-1; prothrombin time and Stuart factor less than 50%; fibrinogen less than 1.5 g.l-1). In spite of quinine therapy, parasitaemia increased from 4 to 35% within 24 h. Using an Haemonetics V50, the exchange of one and a half red blood cell masses was carried out with 17 red blood cell packs. Calcium gluconate was used to prevent the hypocalcaemia induced by the anticoagulant solution. The patient's platelets and plasma were completely reinjected. The result was very satisfactory. This kind of exchange, well tolerated clinically and biologically, would seem better than the classical exchange transfusion. When 10% of the red blood cells are infected by Plasmodium falciparum, it is necessary to exchange from one and a half to two blood masses. Lesser exchanges are always associated with important relapses and quinine therapy must be carried on during and after the exchange. Restricting this exchange only to red blood cells enabled the patient to benefit from his own coagulation factors, antibodies and platelets, and consequently to reduce the number of blood donors involved. However, metabolites (especially bilirubin and circulating immune complexes) were not eliminated. Partial plasmapheresis may be associated with erythropheresis using human albumin as plasma substitute. This technique needs to be assessed, in order to optimize immediate efficiency and post-transfusion infectious risk.
