The treatment of severe falciparum malaria.
In severe falciparum malaria there is a pathophysiological cascade beginning with changes in the parasitized red blood cells which induce intermediate effects, in turn contributing to dysfunction of several organs. A low serum albumin is a common but often unrecognized finding which may contribute to oedema especially in the lung and brain. The only irreversible complication in falciparum malaria is the acute respiratory distress syndrome, manifested by cyanosis and rapid breathing, basically distinct from acute pulmonary oedema caused by therapeutic overhydration. The pathophysiology of falciparum malaria may be complex but the treatment is simple. Drugs, other than antimalarials, are rarely needed. Guidelines for cholorquine or quinine dosage in severe disease are proposed; each drug is given at a dose of 5 to 10 mg/kg in 10 ml/kg of fluid as an intravenous infusion in four hours at a frequency of dosing every 12 to 24 hours. When the disease has been brought under control the treatment should be changed from the intravenous to the oral route.
