Resum

BACKGROUND: Regular anti-malarial therapy in pregnancy, a pillar of malaria control, may affect malaria immunity, with therapeutic implications in regions of reducing transmission. METHODS: Plasma antibodies to leading vaccine candidate merozoite antigens and opsonizing antibodies to endothelial-binding and placental-binding infected erythrocytes were quantified in pregnant Melanesian women receiving sulfadoxine-pyrimethamine (SP) with chloroquine taken once, or three courses of SP with azithromycin. RESULTS: Malaria prevalence was low. Between enrolment and delivery, antibodies to recombinant antigens declined in both groups (p < 0.0001). In contrast, median levels of opsonizing antibodies did not change, although levels for some individuals changed significantly. In multivariate analysis, the malaria prevention regimen did not influence antibody levels. CONCLUSION: Different preventive anti-malarial chemotherapy regimens used during pregnancy had limited impact on malarial-immunity in a low-transmission region of Papua New Guinea. TRIAL REGISTRATIONS: NCT01136850.
