Özet

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. (C) 2016 S. Karger AG, Basel
