ABSTRACT
OBJECTIVE:
To determine the value of measuring amniotic fluid inflammatory biomarkers for diagnosis of subclinical chorioamnionitis.METHODS:
A prospective study was conducted among pregnant women with cervical dilation, preterm premature rupture of membranes, threatened late abortion, or threatened premature labor who attended a tertiary care hospital in Guangzhou, China, between June 1, 2012, and January 31, 2014. Participants were divided into two groups according to the presence or absence of subclinical chorioamnionitis. Surface-enhanced laser desorption/ionization time-of-flight mass spectroscopy (SELDI-TOF-MS) was used to detect human neutrophil defensins (HNP-1 and HNP-2), calgranulins A (S100A8), and calgranulins C (S100A12) in amniocentesis samples.RESULTS:
Overall, 22 patients had subclinical chorioamnionitis and 17 patients did not. Positive test results for HNP-2 were noted for more patients with subclinical chorioamnionitis than for those without for HNP-2 (19 [86%] vs 2 [12%]; P<0.001), HNP-1 (19 [86%] vs 5 [29%]; P=0.001), S100A12 (20 [91%] vs 9 [53%]; P=0.011), and S100A8 (12 [55%] vs 0; P<0.001). When three or four of these biomarkers were present, the accuracy for a diagnosis of subclinical chorioamnionitis was 89.7%. The sensitivity, specificity, positive predictive value, and negative predictive value were 81.8%, 100.0%, 100.0%, and 81.0%, respectively.CONCLUSION:
Detection of inflammatory biomarkers in the amniotic fluid by SELDI-TOF-MS exhibited high diagnostic accuracy for subclinical chorioamnionitis.Palabras clave
