Abstract:

Objective To investigate the predictive value of urinary CXC motif chemokine ligand 10 (uCXCL10) in the risk of death in critically ill children during their stay in the pediatric intensive care unit (PICU). Methods A total of 323 critically ill children admitted to PICU from September to December 2016 and from December 2017 to January 2018 were selected as the research objects. The patients were divided into survival group (295 cases) and death group (28 cases) according to the outcome during hospitalization in PICU, and the clinical characteristics of the children were compared between the groups. The uCXCL10 levels were serially measured during the first week after PICU admission using an enzyme-linked immunosorbent assay. Stepwise multivariate linear regression analysis were used to determine the correlation between uCXCL10 levels and clinical variables. Multivariate logistic regression analysis were performed to investigate the association of uCXCL10 with mortality after adjusting for confounders. The area under the ROC curve (AUC) was calculated to assess the predictive value of uCXCL10 in mortality of critically ill children. Results The initial and maximum values of uCXCL10 in the death group were significantly higher than those in the survival group (P<0.05). Both stepwise multivariate linear regression and multivariate logistic regression analysis showed that the initial and maximum values of uCXCL10 were significantly associated with mortality (P<0.05). The AUC values of initial and maximum uCXCL10 for predicting death in critically ill children were 0.780 (95%CI: 0.689-0.872, P<0.001) and 0.846 (95%CI: 0.769-0.923, P<0.001), respectively. Conclusion The uCXCL10 is an independent predictor of death in critically ill children.
