Abstract
Kawasaki disease (KD) is an acute systemic vasculitis in children. Coronary artery lesions (CALs) are the most serious complications in KD, but the pathogenesis is still unclear so far. Adropin, a new biopeptide, plays an important role in metabolism and cardiovascular function. The aim of this study was to explore the relationship between adropin and KD. 66 KD patients and 22 healthy controls (HCs) were included in the study. KD patients were divided into KD with coronary artery lesions (KD-CALs) group and KD without CALs (KD-NCALs) group. The levels of serum adropin were determined by enzyme-linked immunosorbent assay (ELISA). Compared with the HC group, adropin concentrations were significantly increased in the KD group (p < 0.05), and the KD-CAL group had higher levels of adropin than those in the KD-NCAL group (p < 0.05). Pct (Procalcitonin) and DD (D-dimer) were positively correlated with adropin in the KD group (p < 0.05). Moreover, adropin had positive correlations with CRP (C-reactive protein) and DD in the KD-NCAL group and positive correlations with Pct, PLR (platelet-to-lymphocyte ratio), and DD in the KD-CAL group (p < 0.05). The receiver operating characteristic (ROC) curve showed that the best threshold value of serum adropin level was more than 2.8 ng/mL, with 72.2% sensitivity and 71.4% specificity for predicting CALs in children with KD. Conclusion: Adropin might be involved in the pathogenesis of KD and CALs and can be used as an auxiliary diagnostic biomarker of KD. What is Known: • CALs in KD were mainly caused by inflammation, immune imbalance, and vascular endothelial dysfunction, and adropin is involved in metabolic diseases and cardiovascular diseases. What is New: • In this study, we have found the relationship between adropin and KD, and serum adropin level can be used as an auxiliary diagnostic biomarker to predict CALs in KD.
