Host and Parasite Factors That Influence Susceptibility to Malaria Infection and Disease During Pregnancy and Early Childhood in Ouelessebougou and Bamako, Mali

Malaria caused by Plasmodium falciparum continues to be a global problem with devastating consequences. A greater understanding of the immunologic and parasitologic factors associated with infection and disease is badly needed; and will accelerate the development of highly protective vaccines for both mothers and children. Pregnancy malaria is associated with low birth weight, maternal anemia, and gestational hypertension, and both inflammation and the fetal response to infection may contribute to these poor outcomes. Childhood malaria is a major cause of mortality, and we have found that its risk is related to in utero exposure to pregnancy malaria, as well as other host factors like iron status and constitutive cytokine levels. Pregnancy malaria is caused by a distinct parasite binding phenotype, and as our primary hypothesis in this study we speculate that severe childhood malaria parasites may also have distinct features. A longitudinal cohort study will be conducted in Ouelessebougou, Mali, an area of intense seasonal transmission. Up to 2000 pregnant women and their infants and 2000 children aged 0-3 years will be enrolled and followed to age 5 years, with clinical evaluation and periodic venous and peripheral blood samples being obtained. In addition, up to 3000 febrile hospitalized and non-hospitalized children up to 10 years ofd age will be enrolled at the Ouelessebougou district health centers or the Gabriel Toure Pediatric Hospital in Bamako, Mali, with acute and c…
