Background: This study is aimed at comparing the early diagnostic accuracy of maternal blood white blood cell (WBC) count, C-reactive protein (CRP) and procalcitonin in predicting early onset neonatal sepsis (EONS) among early preterm premature rupture of membrane (PPROM) pregnancies. Methods: A total of 57 consecutive pregnancies, complicated with PPROM, between 24 and 34 gestational weeks were recruited to the study at Suleymaniye Maternity Education and Research Hospital, Istanbul, Turkey between January 2012 and January 2013. All patients were hospitalized and followed up with expectant management. Maternal blood WBC count, CRP and procalcitonin levels were measured in the first 12 h of membrane rupture. EONS was diagnosed using clinical and laboratory findings, and obstetric and neonatal outcomes were noted. Results: The cutoff value for maternal blood CRP was ≥9.49 mg/dl. This value predicted EONS with 77.8% sensitivity, 80.0% specificity, 77.8% positive predictive value (PPV) and 80.0% negative predictive value (NPV). The cutoff value for maternal blood procalcitonin was 0.071 ng/ml. This value predicted EONS with 85.2% sensitivity, 86.7% specificity, 85.2% PPV and 86.7% NPV. Conclusion: Maternal blood procalcitonin levels were superior to maternal blood CRP and WBC count in predicting EONS. Consequently, the maternal blood procalcitonin level is a clinically useful, non-invasive and reliable biomarker in antenatal prediction of EONS.

Objective:To compare perinatal and short-term neonatal outcomes of adolescent, reproductive age, and advanced maternal age (AMA) pregnancies in a low-income region of İstanbul.Materials and Methods:Three hundred six adolescents, 301 reproductive age, and 303 AMA pregnant women who delivered in Süleymaniye Education and Research Hospital between January 1st 2007, and January 31st 2015, were recruited to the study population. The clinical, obstetric and short-term neonatal outcomes of the women were analyzed retrospectively.Results:Adolescent and AMA pregnancies were associated with severe adverse perinatal and short-term neonatal outcomes compared with reproductive-age women. Adolescent and AMA pregnancies had quite similar risks in obstetric outcomes. Adolescent pregnancies were related with severe adverse short-term neonatal outcomes when compared with advanced maternal age pregnancies.Conclusion:Adolescent and AMA pregnancies should be defined as high-risk pregnancies. Our research indicated that healthcare providers such as obstetricians, midwives, and family physicians should be alert in these populations.
