Objective
To evaluate markers of infection in critically ill neonates and children, comparing lipopolysaccharide-binding protein (LBP) with procalcitonin (PCT), interleukin-6 (IL-6), and C-reactive protein (CRP).
Design and setting
Prospective, observational study in the level III multidisciplinary neonatal and pediatric intensive care unit.
Patients
Sixty patients with systemic inflammatory response syndrome (SIRS) and suspected infection classified into two groups: SIRS/sepsis (n=33) and SIRS/no sepsis (n=27). We included 29 neonates aged less than 48 h (neonates <48 h), 12 neonates older than 48 h (neonates >48 h), and 19 children. Median disease severity was high in neonates aged under 48 h and moderate in neonates aged over 48 h and children.
Interventions
Serum LBP, PCT, IL-6, and CRP were measured on two consecutive days. Area under the receiver operating characteristic (ROC) curve (AUC), sensitivity, specificity, and predictive values were evaluated.
Results
Serum LBP was higher in patients with SIRS/sepsis than in patients with SIRS/no sepsis. AUC for LBP on the first day of suspected infection was 0.89 in the younger neonates, 0.93 in the older neonates, and 0.91 in children.
Conclusions
In critically ill neonates aged under 48 h LBP on the first day of suspected infection is a better marker of sepsis than IL-6 and PCT, and is similar to CRP. In critically ill neonates aged over 48 h and children LBP is a better marker than IL-6 and CRP, and is similar to PCT.
