C-reactive protein in preterm premature rupture of the membranes

The usefulness of maternal C-reactive protein (CRP) measurements in the diagnosis of chorioamnionitis and puerperal and neonatal infectious morbidity was studied among 147 patients with preterm rupture of the membranes (PROM). Thirty-three patients developed chorioamnionitis, 10 patients developed puerperal endometritis, and 21 newborn infants developed neonatal infections. There was no difference in the highest antepartum CRP between patients with or without chorioamnionitis. The overall test performance for CRP was poor suggesting that elevated antepartum CRP may be misleading in the diagnosis of chorioamnionitis. However, use of serial CRP measurements increases the test performance. The high negative predictive value suggests that CRP is useful in predicting the absence of chorioamnionitis.
