Analysis of factors associated with development of Bacille Calmette-Guérin inoculation site change in patients with Kawasaki disease.

Objective The present study was performed to identify factors associated with a Bacille Calmette-Guérin (BCG) inoculation site change in patients with Kawasaki disease (KD). Methods Among patients who had received BCG vaccination and treatment for KD at our hospital from 2005 through 2016, 177 patients born in 2005 through 2016 were enrolled. The patients were divided into those with (n = 83, change group) and without (n = 94, no-change group) a BCG site change, and the patient demographics, clinical severity, blood examination results, and echocardiographic findings were compared between the two groups.
