Association of subclinical markers of inflammation with preterm premature rupture of membranes and adverse neonatal results: a case control study.

Abstract

The study aims to investigate the relationship between subclinical inflammatory factors, which are known to be closely related to inflammation, with preterm premature rupture of membranes (PPROM) and adverse postpartum outcomes. The case control type study was conducted between January 1, 2021, and January 2022. 525 pregnant women, including 272 PPROM and 253 normal patients, were added to the study. There was a positive relationship between PPROM and PCT (platelet crit), MPV (mean platelet volume), NLR (neutrophil-to-lymphocyte ratio), and MLR (monocytes to lymphocyte ratio) values. ROC analysis, PCT > 0.19, MPV > 8.78, NLR > 2.82, and MLR > 0.24 were significantly related to improved risk of PPROM (P < 0.05). In logistic regression analysis, a one-unit rise in PCT resulted in a 3.9-fold rise in RDS risk and a one-unit increase in NLR resulted in a 1.6-fold significant rise in sepsis risk (p < 0.05). NLR and PCT parameters were found to be related to adverse neonatal outcomes.
