The effect of vitamin D status on the occurrence of Kawasaki Disease: a meta-analysis

Abstract

Abstract Aim The relationship between vitamin D status and Kawasaki Disease (KD), as well as coronary artery lesion (CAL), has yet to be established. Methods A meta-analysis was conducted to assess the correlation between vitamin D status and KD, as well as the impact of vitamin D status on the progression of KD into CAL. Results The meta-analysis revealed a consistent and significant association between serum 25(OH)D level and the occurrence KD (studies N = 22; z = -3.51, P < 0.001). Patients with KD had markedly lower levels of vitamin D than healthy controls (SMD: -1.30 ng/mL, 95%CI: -2.05 to -0.55 ng/mL). Conclusion The study provided evidence supporting a significant association between lower serum vitamin D levels and the occurrence of KD, particularly within the Chinese population. However, the findings did not suggest a direct impact of vitamin D on the development of CAL in KD patients.
