Predictive value of combined amniotic fluid proteomic biomarkers and interleukin-6 in preterm labor with intact membranes
2009
Objective To assess proteomic biomarkers and interleukin-6 alone or in combination to predict intraamniotic infection, preterm birth, and neonatal morbidity in preterm labor with intact membranes. Study Design Amniotic fluid interleukin-6 and selected proteomic biomarkers were assayed from 86 patients with preterm labor and intact membranes (22-36 weeks). The predictive value of each marker alone or in combination was evaluated for intraamniotic infection, preterm birth, and neonatal composite morbidity. Results Both interleukin-6 (odds ratio, 19.5; P = .012) and proteomic biomarkers (odds ratio, 25.2; P = .001) were statistically independent predictors of intraamniotic infection with sensitivity, positive predictive value, and false-positive rates of 25%, 17.6%, and 20% when 1 marker was present and of 75%, 75%, and 4.3% when both were detected. Their combination did not improve prediction of preterm birth or neonatal morbidity. Conclusion The combined use of proteomic biomarkers and interleukin-6 to predict intraamniotic infection shows better accuracy than when used alone.
