Malaria in pregnancy: baby steps.

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Global Health

Background:

• Malaria in pregnancy disproportionately affects pregnant women and infants, particularly in Africa, where risk has increased.
• Submicroscopic malaria infections are increasingly recognized but difficult to detect and their impact on disease and transmission remains unclear.
• Current treatment guidelines face challenges with late antenatal clinic attendance and drug resistance.

Purpose of the Study:

• To review the current landscape of malaria in pregnancy, focusing on challenges and recent advancements.
• To highlight the impact of malaria on pregnancy outcomes and the complexities of treatment and prevention.
• To discuss emerging strategies for malaria prevention and control in pregnant populations.

Main Methods:

• Review of recent scientific literature on malaria in pregnancy.
• Analysis of trends in malaria risk and treatment efficacy.
• Examination of the biological mechanisms of placental malaria and vaccine development.

Main Results:

• Global decrease in malaria risk for pregnant women, except in Africa where it has risen.
• Artemether-lumefantrine is recommended for first-trimester treatment, but late presentation is common.
• Sulfadoxine-pyrimethamine resistance is increasing, and alternatives like dihydroartemisinin-piperaquine show mixed results for pregnancy outcomes.
• Malaria negatively impacts placental development and fetal growth, leading to small-for-gestational-age infants.

Conclusions:

• Despite progress in understanding and potential new interventions, significant obstacles remain in controlling malaria in pregnancy.
• Further research into non-malarial effects of treatments and vaccine development targeting the VAR2CSA protein shows promise.
• Optimism for improved prevention and control is warranted, but continued efforts are essential to overcome existing challenges.
