The pathogenesis of coronary artery lesions (CALs) in KD patients has been thought of as an unknown stimulus that triggers an inflammatory cascade with activation of the immune system. However, interleukin-23 (IL-23) is supposed as a key cytokine in inflammatory and autoimmunity diseases. The role of IL-23 in the pathogenesis of CALs has not been fully elucidated. This study explored the relationship between the serum IL-23 levels and CALs in patients with KD. We collected blood specimens from

Levels of IL-23, IL-6, IL-17A, IL-10, MCP-1 and VEGF were measured in 190 cases, including 4 groups: KD with CALs (n = 46), KD without CALs (n = 44), febrile control group, (FC, n = 40) and normal control group, (NC, n = 60). Clinical parameters were tested in all subjects. IL-23 was significantly elevated in the KD group compared with the febrile and normal control groups, especially increased in the KD patients with CALs. Serum levels of IL-23 in KD patients were positively associated with WBC, CRP, IL-6, IL-17A, IL-10, MCP-1, and VEGF in children with KD. In conclusion, IL-23 may be involved in the pro-inflammatory process and the pathogenesis of CALs in KD patients.
