Overview

Prospective cohort study investigates sFlt-1/PlGF ratio associations with maternal and neonatal outcomes, suggesting implications for placental health.

Key Points

  • This study examines the relationship between the sFlt-1/PlGF ratio and both maternal and neonatal outcomes in low-risk term pregnancies.
  • Prospective cohort study of 87 women with singleton term pregnancies
  • Measured serum sFlt-1 and PlGF at admission before delivery
  • Used multivariable regression models to analyze associations with maternal and neonatal outcomes.
  • Doubling of the sFlt-1/PlGF ratio increased estimated peripartum blood loss by 78.0 mL (95% CI 42.1–113.9; p < 0.001)
  • Higher ratio correlated with a postpartum hemoglobin decline of 0.078 g/dL (95% CI 0.008–0.148; p = 0.030)
  • Each doubling of the ratio was linked to a decrease in neonatal birthweight of 64.6 g (95% CI −102.0 to −27.2; p = 0.001).
