Analysis of Risk Factors of Kawasaki Disease With Coronary Artery Lesions

Objective: To identify factors predictive of coronary artery lesions (CALs) in children with Kawasaki disease (KD). Methods: : The clinical data of 420 children with KD who were hospitalized between January 2018 and December 2020 were retrospectively evaluated after assignment to groups by the presence of coronary artery aneurysm (CAA), coronary artery dilation (CAD), or no CALs. The association between coronary artery damage and patient clinical and laboratory values was investigated by pairwise comparison of the three groups. Univariate and multivariate logistic regression identified independent risk factors. The predictive value of patient variables for development of CAA and CAD was estimated by receiver operating characteristic curve analysis. Results: : CALs occurred in 17.6% (94/420) of children with KD. Duration of fever, cervical lymphadenopathy, intravenous immune globulin resistance, immunoglobulin (Ig)A, procalcitonin, hemoglobin (Hb), erythrocyte sedimentation rate (ESR), C-reactive protein, and others differed between patients with CALs and without CALs and were significantly associated with the development of CAA and CAD. The largest area under the curve was for combined CAA or CAD indicators, 0.851 for CAA (sensitivity of 68.09% and specificity of 60.62%) and 0.714 for CAD (sensitivity of 65.96% and specificity of 70.77%). Fever of >7 days before treatment was predictive of severe CAA or CAD. Conclusion: Fever duration, ESR, IgA, Hb, and cervical lymphadenopathy were independent risk factors of CAA; CRP, ESR, and cervical lymphadenopathy were independent risk factors of CAD, with combined factors having increased sensitivity and specificity. Early, active treatment is essential to reduce the occurrence of CALs.
