Question: Can adrenomedullin (ADM) or interleukin-6 (IL-6) detect late-onset neonatal sepsis (LOS) at admission (area under the curve [AUC]>0.90) as an early diagnostic marker?
Finding: Only IL-6 consistently distinguished survivors from nonsurvivors (AUC>0.90) on admission and antibiotic treatment days 3 and 7. C-reactive protein level identified infections from day 3 but failed to predict outcomes (AUC<0.70).
Meaning: IL-6 level can improve LOS diagnosis and prognosis.
