Treatment of severe falciparum malaria during pregnancy with quinidine and exchange transfusion.

Malaria during pregnancy may be associated with significant morbidity and mortality in both mother and fetus. Treatment of severe chloroquine-resistant malaria during pregnancy may be problematic since quinine and related compounds may have a deleterious effect on the course of labor. This article reports the case of a 21-year-old primigravida Liberian woman who presented with high-grade (greater than 12%) parasitemia with Plasmodium falciparum. The patient was initially treated with chloroquine; however, she developed bilateral pulmonary infiltrates and premature labor, and her condition appeared to clinically deteriorate. Therapy was changed to intravenous quinidine, and red blood cell exchange transfusion was instituted. This resulted in a decreased parasitemia and clinical improvement. The patient underwent a cesarean section, and a healthy child was delivered. Although most cases of malaria may be managed with conventional chemotherapy, the use of intravenous quinidine in combination with exchange transfusion with careful monitoring should be considered in selected cases of severe, complicated malaria in pregnant women.
