Abstract
This study was performed to evaluate the diagnostic performance of maternal serum C-reactive protein, maternal white blood cell (WBC), and neutrophil counts in the detection of histologic chorioamnionitis. One hundred and twenty six pregnant women after at least 28 weeks of gestation with premature rupture of membranes (PROM) were studied. Blood samples for C-reactive protein, WBC and neutrophil counts were taken at delivery. Placental histology was evaluated for histologic chorioamnionitis. Maternal and neonatal complications were observed. Among women with and without histologic chorioamnionitis, the maternal WBC and neutrophil counts were different (P<0.05) but the maternal serum C-reactive protein was not. Cutoff values for C-reactive protein, WBC, and neutrophil counts were 0.5 mg/dL, 15,000 cell/mm3, and 80 per cent, respectively. Sensitivity and specificity were 56 per cent and 58 per cent for C-reactive protein, 60 per cent and 63 per cent for WBC count, and 62 per cent and 54 per cent for neutrophil count, respectively. In conclusion, the maternal serum C-reactive protein, WBC, and neutrophil counts have poor diagnostic performance for histologic chorioamnionitis.
