Positive Maternal C-Reactive Protein Predicts Neonatal Sepsis

ABSTRACT

PURPOSE: To evaluate the diagnostic performance of maternal inflammatory marker C-reactive protein (CRP) in predicting early onset neonatal sepsis (that occurring within 72 hours after birth). MATERIALS AND METHODS: 126 low birth weight newborns (gestation 32+/-3.2 wk, birth weight 1887+/-623 g) and their mothers were included. Neonates were divided into sepsis group (n=51) including both proven (positive blood culture) and suspected (negative blood culture but with more than 3 abnormal clinical signs), and controls (n=75). Mothers were subgrouped into CRP positive > or =1.22 mg/dL (n=48) and CRP negative 1.22 mg/dL) had sensitivity 71% and specificity 84% for predicting neonatal sepsis. Maternal CRP positive group had more neonatal sepsis than CRP negative group (71% vs. 29%, p or =1.22 mg/dL). In newborn of CRP positive mother, the clinician may be alerted to earlier evaluation for possible neonatal infection prior to development of sepsis.
