Abstract

During gestational malaria, Plasmodium falciparum-infected erythrocytes can sequester within the placenta, contributing to poor pregnancy outcomes, especially low birth weight. In children and non-pregnant adults, pigmented leukocytes may serve as markers of sequestered parasite burden and predict clinical outcomes. Here, we investigated circulating pigmented leukocyte numbers as predictors of clinical outcomes in pregnant women presenting with malaria at enrolment. The number of circulating pigmented neutrophils at enrolment negatively correlated with birth weight (Rho=-25, P=.04), suggesting these cells may have a pathogenic role in, and could serve as prognostic markers for, malaria-assoc..
