Changes in Maternal Blood Inflammatory Markers As a Predictor Of Chorioamnionitis: A Prospective Multicenter Study. (29th September 2014) - Le Ray, Isabelle
Abstract Problem To evaluate the inflammatory pattern in maternal circulation from women with preterm premature rupture of membranes (PPROM) considering the occurrence of histologically confirmed chorioamnionitis (HCA). Method of study A prospective study was conducted in 121 women with PPROM between 24 and 34 + 0 weeks of gestation. Association between white blood cells (WBC) count, plasma CRP, IL‐6, MCP‐1 and IP‐10 levels, and HCA was assessed. Results The rate of HCA was 44.7% (54/121). During the 5 days preceding delivery, median CRP, WBC, and IL‐6 levels were significantly higher in the HCA than in no‐HCA group (P < 0.001). Variations in IL‐6, IP‐10 levels, during the 24–72 hr before delivery, were predictors of the occurrence of HCA, but the diagnostic accuracy was low [Receiver Operating Characterictic (ROC) curve, area under the curve (AUC) = 0.56]. Conclusion An increase in IL‐6, CRP, IP‐10 maternal plasma levels was confirmed in PPROM women with HCA. Longitudinal follow‐up of these markers did not add valuable information regarding HCA.
