    Abstract:
    BACKGROUND: Previous studies demonstrated that coronary artery lesions (CALs) resulting from Kawasaki disease (KD) can improve over time. However, limited information is available on sub-acute outcomes of CALs detected at admission during KD illness. METHODS: The nationwide Japanese KD survey contained substantial information on KD patients with CALs detected at admission and who received standard IVIG treatment within 10 days of disease onset. Coronary outcomes were evaluated by changes in CALs from admission to the first assessment at 30 days from disease onset in three categories: improved, unchanged, and progressed. Ordinal logistic regression analysis was performed to evaluate factors associated with the outcomes. RESULTS: Of 2024 patients with CALs detected at admission, improved, unchanged, and progressed outcomes were found in 1548 (76.5%), 390 (19.3%), and 86 (4.2%), respectively. Over 80% of patients with coronary artery (CA) dilatations had improved outcome. Independent factors associated with worse outcomes were larger-size CALs (adjusted ORs [95% CIs]: CA aneurysm = 5.13 [3.65-7.22] and giant CA aneurysms = 7.49 [3.56-15.72] compared with CA dilatation, respectively), age ≥ 60 months (1.45 [1.08-1.94] compared with 12-59 months), recurrent KD (1.57 [1.07-2.29]), parental history of KD (2.23 [1.02-4.85]), and delayed admission (8-10 days from disease onset: 1.76 [1.21-2.57] compared with 1-4 days). CONCLUSIONS: KD patients with larger CALs, ≥60 months old, and with recurrent status or parental history may require more rigorous treatment. In addition, delayed admission may result in worse coronary outcome, indicating that prompt diagnosis and treatment are required.
