Abstract:
Objective:To investigate clinical significance of Presepsin(soluble CD14 subtype) in the diagnosis and condition assessment of sepsis in children compared with traditional biomarkers.Methods:For the prospective study, 102 children with sepsis admitted to the PICU of the Children′s Hospital of the Capital Institute of Pediatrics from January 2017 to December 2018 were selected, including 57 cases in the sepsis group, 45 cases in the severe sepsis/septic shock group and 25 cases in the non-infectious systemic inflammatory response syndrome(SIRS group), and 35 children with healthy physical examination during the same period as the control group.The sepsis group was further divided into the survival group( n=86)and the death group( n=16)based on the 28-day mortality.The data collected included serum Presepsin, procalcitonin(PCT), C-reaction protein(CRP) and interleukin(IL)-6 levels on days 1, 3 and 7 of admission, and compared with paediatric critical case scores. Results:(1)The levels of serum Presepsin [12.43(7.21, 15.07) ng/mL], PCT [23.00(5.70, 87.00) ng/mL], CRP [160.0(105.5, 200.0) mg/L], IL-6 [1 000.0(125.0, 1, 000.0) pg/mL] were significantly higher than those in the sepsis, SIRS and control groups( P<0.001). (2) The area under the ROC curve(AUC) values for Presepsin, PCT, and IL-6 subjects on day 1 of admission were 0.856, 0.812, and 0.516, respectively.The sensitivity of Presepsin at a cut-off value of 4.40 ng/mL for the diagnosis of sepsis was 81.1% and the specificity was 72.3%, which would significantly higher diagnostic efficacy of the combination of Presepsin, PCT and IL-6.(3) There was a significant difference between the survival and death groups in Presepsin( P<0.001), and Presepsin was significantly higher in the death group on days 3 and 7 than those in the survival group(both P<0.001); IL-6 was significantly higher in the death group on day 3 than that in the survival group( P=0.04); the differences in PCT and CRP between the death and survival groups at all time points were not statistically significant(both P>0.05 ). (4) The AUCs of inflammatory factors on days 1, 3 and 7 to predict sepsis outcome were 0.597, 0.656 and 0.951 for Presepsin, 0.576, 0.613 and 0.655 for PCT and 0.726, 0.786 and 0.664 for IL-6, respectively.The diagnostic values of Presepsin on day 7 and IL-6 on days 1 and 3 were higher.The combination of Presepsin, PCT and IL-6 significantly improved the prognostic judgment of sepsis.(5) The difference between sepsis-related acute kidney injury(AKI) and non-AKI was not statistically significant when comparing Presepsin on day 1 and 3(all P>0.05). Presepsin levels on day 7 were significantly higher in children with sepsis-associated AKI than in those without AKI( P<0.001). Conclusion:Presepsin is a good biomarker for sepsis diagnosis in children, which is equivalent to PCT in the diagnosis of sepsis, superior to IL-6 and superior to PCT in the prognosis evaluation.Combined testing of Presepsin, PCT and IL-6 may improve the diagnosis of sepsis and the assessment of the condition in children.
