Predictive Value of Maternal Serum Pentraxin 3 (PTX 3) and Heparin-binding Protein (HBP) for Chorioamnionitis in Preterm Premature Rupture of Membranes

180 participantsStarted 2022-02-10

Plain-language summary

Objective: The aim of this study was to investigate the predictive value of maternal serum pentraxin 3 (PTX3) and heparin-binding protein (HBP) for chorioamnionitis in preterm premature rupture of membranes (PPROM). Method: This observational prospective cohort study included a total of 180 pregnant women at 24-40 gestational weeks. There were 60 cases of term premature rupture of membranes (TPROM), 60 cases of preterm premature rupture of membranes（PPROM）and 60 cases of healthy women. The concentrations of PTX3 and HBP were measured in maternal blood and amniotic fluid using an enzyme-linked immunosorbent assay (ELISA). Western immunoblotting was used to analyze the expression of PTX3 and HBP in placental tissue. The localization and immunoreaction of PTX3 and HBP in placenta were determined via immunohistochemistry (IHC).
