OBJECTIVE: We sought to evaluate gestational age, cervical length, amniotic fluid interleukin (IL)-6, and selected proteomic biomarkers as independent predictors of adverse outcome in preterm premature rupture of membranes (PPROM). STUDY DESIGN: This was a prospective cohort study of 65 consecutive women with PPROM (20.0-34.6 weeks). Gestational age, cervical length, amniotic fluid IL-6, and proteomic biomarkers (calgranulins A and C, and neutrophil defensins 1 and 2) were evaluated at diagnosis. The predictive value for intraamniotic infection and neonatal composite morbidity was calculated by logistic regression. RESULTS: Proteomic biomarkers were independent predictors of intraamniotic infection (odds ratio, 22.1; P = .011) and neonatal composite morbidity (odds ratio, 17.6; P = .02). With the exception of a trend between gestational age and neonatal morbidity (P = .054), none of the other parameters were independent predictors of outcome measures. CONCLUSION: Selected proteomic biomarkers were the only independent predictors of adverse outcomes in PPROM. Contrary to what is reported in preterm labor with intact membranes, gestational age, cervical length, and IL-6 were not.
