Combining CRP, PCT, and IL-6 can accurately diagnose the hyperinflammatory state of pediatric sepsis and increase the diagnostic specificity. Early diagnosis of organ dysfunction requires a combination of PCT, IL-8, and IL-10.
Background Although early diagnosis and management are critical for prognosis of pediatric sepsis, there are no specific diagnostic biomarkers for the hyperinflammatory state and organ dysfunction, important stages of sepsis. Methods We enrolled 129 children with infection into three groups: non-sepsis infection (33), Sepsis 1.0 (hyperinflammatory state, 67), and Sepsis 3.0 (organ dysfunction, 29). Another 32 children with no infections were included as controls. Serum C-reactive protein (CRP), procalcitonin (PCT), interleukin (IL)-1 beta, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17, tumor necrosis factor (TNF)-alpha, interferon (IFN)-alpha, and IFN-gamma were assessed to diagnose the two stages, and their diagnostic capacities were evaluated using receiver operating characteristic (ROC) curves. We also examined whether combining biomarkers improved diagnostic efficiency. Results Significantly higher CRP, PCT, and IL-6 levels were detected in the Sepsis 1.0 than the non-sepsis infection group (p < 0.001). The areas under the curve (AUCs) for diagnosing Sepsis 1.0 were 0.974 (CRP), 0.913 (PCT) and 0.919 (IL-6). A combination of any two biomarkers increased diagnostic sensitivity to >= 92.54% and specificity to 100.00%. Significantly higher PCT, IL-8, and IL-10 levels were found in the Sepsis 3.0 than the Sepsis 1.0 group (p <= 0.01), with AUCs for diagnosing Sepsis 3.0 0.807 (PCT), 0.711 (IL-8), and 0.860 (IL-10). Combining these three biomarkers increased diagnostic sensitivity to 96.55% and specificity to 94.03%. Conclusion In pediatric sepsis, combining any two of CRP, PCT, and IL-6 can accurately diagnose the hyperinflammatory state and increase diagnostic specificity. Early diagnosis of organ dysfunction requires a combination of PCT, IL-8, and IL-10.
