Maternal Malaria and the Risk of Subsequent Pregnancy Complications

Abstract

Maternal malaria, primarily caused by Plasmodium falciparum, has well-documented immediate effects on pregnancy, including preterm birth, low birth weight, and placental dysfunction. However, its impact extends beyond the current pregnancy, potentially influencing outcomes in subsequent pregnancies. This review examines how maternal malaria affects future pregnancies, focusing on the mechanisms through which previous malaria infections contribute to subsequent complications. Key mechanisms include chronic placental damage, immune system alterations, and persistent inflammation, which can disrupt placental function and increase the risk of adverse outcomes such as preterm labor and placental abruption in future pregnancies. The review highlights evidence that women with a history of maternal malaria are at an elevated risk for complications in subsequent pregnancies, including an increased likelihood of preterm birth and low birth weight. Persistent placental damage and immune dysregulation resulting from past malaria infections contribute to these risks. Understanding these long-term effects is crucial for developing effective public health strategies and interventions aimed at mitigating the risks of adverse pregnancy outcomes in malaria-endemic regions.
