Objective:
To measure maternal and fetal hemodynamics during acute malaria in pregnancy.
Methods:
Time courses of maternal heart rate (MHR), maternal blood pressure (BP), and fetal heart rate (FHR) were performed until 56 days after initiation of anti-malarial treatment with artemether-lumefantrine. Women with malaria were hospitalized for at least 3 days until recovery.
Results:
Mean baseline characteristics of pregnant women with malaria (n=38) versus pregnant women without malaria (n=39) were as follows: gestational age (28.8 vs 24.6 weeks; P=0.006); maximum FHR (165.3 vs 158.3 beats per minute [bpm]; P=0.054); minimum FHR (137.6 vs 128.7 bpm; P=0.016); mean BP (74.7 vs 80.9 mm Hg; P=0.001); pulse pressure (40.3 vs 42.1mm Hg; P=0.300); and MHR (107.4 vs 81.3 bpm; P<0.001). The geometric mean parasite count was 13 795 per μL. Complete time courses were collected from a subgroup of participants. For women with malaria, maternal body temperature and BP normalized within 24 hours and after 72 hours, respectively. The MHR among pregnant women without malaria showed a physiologic increase during pregnancy of approximately 7 bpm between days 0 and 56. The mean FHR among women with malaria normalized after 72 hours.
Conclusion:
Acute malaria induces maternal and fetal hemodynamic changes.
