Patient characteristics.
The demographic characteristics of KD patients and HC were summarized in Table 1. As expected, the WBC, lymphocyte and Lymphocytes counts and the levels of serum ESR and CRP in the patients were significantly higher than that in the HC. Furthermore, the concentrations of serum NT-proBNP in KD patients with CAL were significantly higher than that in KD group with NCAL. In contrast, there was no significant difference in the distribution in the gender and age, and the levels of serum IgG, IgM, IgA, C3 and C4 among the different groups of patients and HCs.
