Pregnancy-associated malaria (PAM) causes maternal anemia and low birth weight, especially in first-time mothers. Intermittent preventive treatment with sulfadoxine-pyrimethamine is the current best policy for preventing PAM.

Area of Science:

  • Tropical Medicine
  • Obstetrics
  • Parasitology

Background:

  • Pregnancy-associated malaria (PAM) poses significant risks, particularly in areas with stable malaria endemicity.
  • Maternal anemia and low birth weight (LBW) are primary consequences, especially affecting primigravidae.
  • HIV-malaria co-infection exacerbates placental malaria severity.

Purpose of the Study:

  • To review the impact of chemoprophylaxis on PAM outcomes.
  • To assess current prevention strategies and explore future therapeutic avenues.

Main Methods:

  • Review of controlled trials on malaria chemoprophylaxis in pregnancy, primarily from Tropical Africa.
  • Analysis of outcomes related to maternal anemia, birth weight, and placental malaria.
  • Consideration of emerging molecular targets for novel interventions.

Main Results:

  • Chemoprophylaxis trials generally show increased mean birth weight and reduced maternal anemia, particularly in primigravidae.
  • Prophylaxis efficacy may be reduced in HIV-malaria co-infection, suggesting a need for adjusted dosing.
  • Intermittent preventive treatment with sulfadoxine-pyrimethamine is identified as the current optimal policy.

Conclusions:

  • Intermittent preventive treatment with sulfadoxine-pyrimethamine, delivered through antenatal clinics, is the most effective current strategy for preventing PAM.
  • Integration of PAM prevention with routine antenatal services is recommended.
  • Future research into molecular receptors offers potential for targeted therapies and vaccines for pregnant women.
