Abstract

Background: Premature Rupture of Membrane (PROM) refers to the rupture of fetal membranes at least 1 hour before the onset of labor pain. The present study intended to determine the predictive value of maternal serum level of Procalcitonin in the early diagnosis of Chorioamnionitis in mothers with PPROM.

Methods: In this prospective cohort study, a total of 48 patients with PPROM were selected as the intended sample size due limited financial resources and in accordance with previous articles in Kosar ward of Motahhari hospital of Urmia city, Iran. Inclusion Criteria were amniotic fluid leak, positive Nitrazine and Fern test, gestational age from 28 to 33 weeks and lack of fetal tachycardia. Exclusion Criteria were chronic and congenital heart disease as well as use of NSAIDs. Data were analyzed using SPSS 19 and descriptive statistics, independent t-test and Pearson test were performed.

Results: The present study was conducted on 48 pregnant women and their neonates. About %39.6 of mothers was pathologically infected with Chorioamnionitis while %60.4 of the patients were not infected with the disease. Moreover, %68.8 of the neonates had a five-minute Apgar score of ≥7. There was a significant correlation between infection of mothers with histopathologic Chorioamnionitis and neonatal hospitalization in NICU (P<0.001). The sensitivity, specificity, positive and negative predictive values of PCT inflammatory index were %100, %79, %57.5 and %100 respectively for the diagnosis of histopathologic Chorioamnionitis.

Conclusion: It was found that there was a significant correlation between PCT index at delivery time and histopathologic Chorioamnionitis.
