Predictive value of Apelin-13 on coronary artery lesion in Kawasaki disease北大核心CSCD

Objective To investigate the relationship between the level of Apelin-13 and coronary artery lesion (CAL) in patients with Kawasaki disease (KD), and assess the predictive value of Apelin-13 for CAL in acute phase of KD. Methods A total of 240 children with KD treated in Chengdu Women and Children's Central Hospital from September 2017 to October 2019 were recruited, and were divided into KD with CAL (KD CAL) group and KD without CAL (KD-NCAL) group.Thirty children with acute upper respiratory infection and 30 healthy children were recruited into the febrile control group and the healthy control group, respectively.Blood routine and serum levels of albumin, C-reactive protein (CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP) and Apelin-13 were mea-sured in KD children prior to intravenous gamma globulin injection and after the diagnosis of children in the febrile control group and physical examination of children in the healthy control group.The clinical data of children in each group were compared, and the risk factors of KD complicated with CAL and the predictive value of Apelin-13 were determined by using receiver operating characteristic (ROC) curve and multiple Logistic regression analysis. Results Apelin-13 and hemoglobin in children with KD were significantly decreased compared with those in the healthy control group and fever control group (all P<0.001). However, white blood cell(WBC) count, platelet count, CRP and NT-proBNP in KD group were significantly increased compared with those in the healthy control group and fever control group (all P<0.001). Serum albumin in KD children was significantly lower than that in the healthy control group (P=0.004), and there was no difference when compared with the fever control group (P=0.485). Apelin-13 and hemoglobin were significantly decreased in KD-CAL group compared with KD-NCAL group (t=10.102, P<0.001; t=2.034, P=0.043), while NT-proBNP and CRP were significantly increased (t=5.982, 3.728, all P<0.001). Multiple logistic regression analysis showed that Apelin-13 and NT-proBNP were independent predictors of CAL in KD.The ROC curve analysis showed that the cut-off value of Apelin-13 for predicting CAL was 2.99 μg/L, with an area under the curve (AUC) of 0.869 (95%CI: 0.820-0.909), sensitivity of 77.78% and specificity of 88.67%.While NT-proBNP cutoff value of 822 ng/L yielded sensitivity of 57.78% and specificity of 84.62% for predicting CAL with an AUC of 0.718(95%CI: 0.656-0.774). Conclusions Apelin-13 plays a protective role in KD complicated with CAL, and could be used to predict CAL in the acute phase of KD. © 2022 Chin J Pathol, June. All rights reserved.
