Adverse Neonatal Outcome of Pregnancies Complicated by Preeclampsia

Area of Science:

• Obstetrics and Gynecology
• Neonatology
• Perinatal Medicine

Background:

• Infants born to mothers with preeclampsia face significant clinical challenges and early-onset complications.
• Available treatments do not fully mitigate risks for these vulnerable newborns.
• Preeclampsia's impact on neonatal outcomes necessitates improved predictive tools and management strategies.

Purpose of the Study:

• To evaluate early-onset complications in infants born to preeclamptic mothers.
• To correlate infant clinical status with maternal serum angiogenesis markers (sFlt-1, PlGF).
• To assess the predictive value of the sFlt-1/PlGF ratio for adverse neonatal outcomes.

Main Methods:

• Study included 77 newborns and their mothers diagnosed with preeclampsia.
• Infants were assessed for perinatal outcomes, focusing on adverse neonatal outcomes (infections, RDS, PDA, NEC, IVH, ROP, BPD).
• Receiver Operating Characteristic (ROC) curve analysis determined cutoff points for sFlt-1/PlGF ratio and gestational age (32 weeks).

Main Results:

• Higher sFlt-1/PlGF ratios were associated with longer hospitalization and increased incidence of adverse neonatal outcomes.
• Neonates born at or before 32 weeks gestation with higher sFlt-1/PlGF ratios had significantly more adverse outcomes.
• Infants born after 33 weeks gestation experienced minimal severe neonatal complications.

Conclusions:

• The sFlt-1/PlGF ratio is a valuable tool for predicting short-term adverse neonatal outcomes in preeclampsia.
• Gestational age, particularly before 32 weeks, is a critical factor in neonatal complication risk.
• Effective preeclampsia screening and preventive care are crucial for reducing neonatal morbidity.
