Maternal platelet to lymphocytes ratio at delivery can predict poor neonatal outcome in preterm births

Objectives: This study was conducted to determine the role of platelet to lymphocytes ratio (PLR) in predicting poor neonatal outcome among preterm births (PTB).
Methods: The medical records of 439 preterm births and 200 normal pregnancies were reviewed retrospectively with utilization of some personal, obstetric data as well as the complete blood count reports.
Results: In this study, there is significant poor neonatal outcome among PTB in regard to birth weight, APGAR score, morbidity and mortality. Significant area under the curve (AUC = 0.647, p= 0.026) by the ROC curve for PLR in PTB. Significant poor outcome for preterm neonates delivered to mothers with PRL ≥ 80 at delivery for low APGAR score, respiratory distress syndrome, intraventricular hemorrhage and perinatal death. Significant negative correlation between maternal PLR at delivery and birth weight as well as gestational age of PTB.
Conclusion: This study concluded that maternal PLR at delivery has significant relationship to neonatal outcome. It can predict preterm neonates with poor outcome.
