摘　　要：BACKGROUND Preeclampsia(PE)is a pregnancy syndrome of undetermined etiology;inflammation was one of the proposed theories for its development.AIM To examine the platelet to lymphocyte ratio(PLR),an inflammatory biomarker,as a marker to predict poor maternal-neonatal outcomes in early-onset PE(EoPE).METHODS A cross-sectional study enrolled 60 pregnant women with EoPE(at 32-30 wk of gestation)at a university hospital.Demographic criteria and hematological indices were collected,including platelet counts and indices(mean platelet volume and platelet distribution width),PLR,and the Doppler study,which calculated estimated fetal weight(EFW),amniotic fluid index(AFI),resistance index(RI),and pulsatility index(PI).Participants were followed until delivery,where maternal outcomes were recorded,including;delivery mode and reason for cesarean section,and neonatal outcomes,including fetal growth restriction(FGR),meconium-stained liquid,the 5-min Apgar score,and admission to the intensive care unit.RESULTS There was a trend of insignificant increases in cesarean sections.Sixty-one-point two percent(37/60)fetuses were admitted to the neonatal care unit;70.0%of admitted fetuses were meconium-stained liquor,and 56.7%of them had FGR.PLR was positively correlated with AFI and EFW as r=0.98,0.97,P<0.001;PLR showed negative correlations with PI and RI as r=-0.99,-0.98,P<0.001.The Apgar score and the number of days admitted to the intensive care unit had a positive and negative correlation(0.69,-0.98),P<0.0001,respectively.Receiver operating characteristic calculated a PLR cutoff value(7.49)that distinguished FGR at 100%sensitivity and 80%specificity.CONCLUSION Strong,meaningful relationships between PLR and FGR parameters and a poor neonatal outcome with a significant P value make it a recommendable biomarker for screening EoPE-related complications.Further studies are suggested to see the impact on maternal-neonatal health.
