ABSTRACT
AIM: Term pregnancy complicated by premature rupture of membranes (PROM) is thought to be associated in part with subclinical infection, and places mothers and neonates at an increased risk for several complications. Therefore, perinatal care would be greatly helped if a reliable clinical measure were available for predicting the incidence of PROM. METHODS: One hundred and ninety-six pregnant women who consented to enter this study were screened using a method developed to assess active ceruloplasmin in cervicovaginal secretion as a clinical marker for predicting the incidence of PROM. Cervicovaginal secretions were obtained from the cervical canal at about 36 weeks of pregnancy. The active ceruloplasmin level in the cervicovaginal secretion was measured using an original enzyme-linked immunoabsorbent assay. RESULTS: Of 196 women, 27 women (13.8%) developed PROM and 169 women (86.2%) did not develop PROM. Active ceruloplasmin in the cervicovaginal secretion was significantly higher in the PROM group than in the non-PROM group (P < 0.001). Analysis using receiver-operating characteristic curves showed that the active ceruloplasmin level (1420.0 ng/mL) proved to be the proper cut-off value to best predict the incidence of PROM. CONCLUSION: Active ceruloplasmin in the cervicovaginal secretion might be a reliable clinical marker for term PROM.
