Abstract:
Objective To investigate the relationship between the levels of macrophage migration inhibito-ry factor(MIF),lipoprotein-associated phospholipase A2(Lp-PLA2)and chemokine CC motif ligand 3(CCL3)in peripheral blood and severity of disease and complication of acute kidney injury in neonatal sepsis.Methods A total of 112 children with NS admitted to this hospital from May 2021 to May 2024 were selected as the research objects.According to the neonatal acute physiology score Ⅱ(SNAP-Ⅱ score),they were di-vided into mild group(71 cases)and severe group(41 cases),and according to whether the children were complicated with AKI,they were divided into AKI group(47 cases)and non-AKI group(65 cases).In addi-tion,112 healthy neonates who underwent physical examination in the hospital during the same period were selected as the control group.The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood were detected in each group.Pearson correlation analysis was used to analyze the correlation between the levels of MIF,Lp-PLA2 and CCL3 in peripheral blood and the severity of NS.Multivariate Logistic regression was used to analyze the influencing factors of AKI in children with NS.The receiver operating characteristic(ROC)curve was drawn to evaluate the predictive value of peripheral blood MIF,Lp-PLA2 and CCL3 for the severity of NS and the complication of AKI in NS.Results The levels of MIF,Lp-PLA2 and CCL3 in the severe group were higher than those in the mild group and the control group(P<0.05),and those in the mild group were higher than those in the control group(P<0.05).The severe group had a significantly higher SNAP-Ⅱ score than the mild group(P<0.05).The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood of NS children were posi-tively correlated with SNAP-Ⅱ score(r=0.512,0.463,0.547,P<0.05).The area under the curve(AUC)of peripheral blood MIF,Lp-PLA2 and CCL3 in the diagnosis of severe NS was 0.782,0.772 and 0.753,respec-tively.The AUC of combined diagnosis was 0.888,which was higher than that of individual indicators(P<0.05).The levels of MIF,Lp-PLA2 and CCL3 in AKI group were higher than those in non-AKI group(P<0.05).Neonatal asphyxia,high levels of MIF,Lp-PLA2,and CCL3 were risk factors for AKI in children with NS(P<0.05).The AUC of MIF,Lp-PLA2 and CCL3 in predicting AKI in children with NS were 0.770,0.759 and 0.757,respectively.The AUC of the combined prediction of MIF,Lp-PLA2 and CCL3 was 0.910,which was higher than that of each index alone(P<0.05).Conclusion The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood of children with NS are increased,which are closely related to the aggravation of NS and the development of AKI.The combined detection of MIF,Lp-PLA2 and CCL3 has a high value in the as-sessment of the severity of NS and the risk of AKI.
