Background. Gestational malaria is a major public health problem. It produces fetal complications such as low birth weight, perinatal mortality, and congenital malaria. The present study is aimed at determining the prevalence of congenital malaria and its neonatal complications in the city of Kisangani. Methods. We conducted a cross-sectional study in Kisangani from 1 January to 30 September 2018. Our study population was composed of 1248 newborns born in our study sites, during the period of our study. Just after their birth, we performed the thick drop smear in the placental print and in umbilical blood smear. Results. The prevalence of congenital malaria was 13.98%; 69.23% of newborns who contracted congenital malaria were from 18- to 34-year-old mothers, 53.85% from primiparous mothers, 92.31% from mothers who took intermittent preventive treatment in pregnancy with Sulfadoxine-Pyrimethamine, all (100%) from mothers using the insecticide-treated mosquito nets and 7.69% from HIV-positive mothers. Low birth weight and perinatal mortality were recorded in 76.92% and 7.69% of congenital malaria cases, respectively. Intermittent preventive treatment in pregnancy with Sulfadoxine-Pyrimethamine had no effect on congenital malaria (FE=0.5218; OR: 0.8, 95% CI: 0.1651-3.8769) and on low birth weight (FE=0.3675; OR: 1.2308, 95% CI: 0.0037-0.1464); however, it seemed to have protective effect against perinatal mortality (FE=0.0001; OR: 0.0233, 95% CI: 0.0037-0.1464). Conclusion. Congenital malaria remains a major problem in stable malaria transmission area like Kisangani, and it is grafted by major perinatal complications, particularly low birth weight and perinatal mortality. We recommend an extended study to clarify the relationship between the outcome of pregnancy and the intermittent preventive treatment in pregnancy with Sulfadoxine-Pyrimethamine.

In pregnancy, iron deficiency and iron overload increase the risk for adverse pregnancy outcomes, but the effects of maternal iron status on long-term child health are poorly understood. The aim of the study was to systematically review and analyze the literature on maternal iron status in pregnancy and long-term outcomes in the offspring after birth. We report a systematic review on maternal iron status during pregnancy in relation to child health outcomes after birth, from database inception until 21 January 2021, with methodological quality rating (Newcastle-Ottawa tool) and random-effect meta-analysis. (PROSPERO, CRD42020162202). The search identified 8139 studies, of which 44 were included, describing 12,7849 mother–child pairs. Heterogeneity amongst the studies was strong. Methodological quality was predominantly moderate to high. Iron status was measured usually late in pregnancy. The majority of studies compared categories based on maternal ferritin, however, definitions of iron deficiency differed across studies. The follow-up period was predominantly limited to infancy. Fifteen studies reported outcomes on child iron status or hemoglobin, 20 on neurodevelopmental outcomes, and the remainder on a variety of other outcomes. In half of the studies, low maternal iron status or iron deficiency was associated with adverse outcomes in children. Meta-analyses showed an association of maternal ferritin with child soluble transferrin receptor concentrations, though child ferritin, transferrin saturation, or hemoglobin values showed no consistent association. Studies on maternal iron status above normal, or iron excess, suggest deleterious effects on infant growth, cognition, and childhood Type 1 diabetes. Maternal iron status in pregnancy was not consistently associated with child iron status after birth. The very heterogeneous set of studies suggests detrimental effects of iron deficiency, and possibly also of overload, on other outcomes including child neurodevelopment. Studies are needed to determine clinically meaningful definitions of iron deficiency and overload in pregnancy.
