Compared with a 5% intravenous immunoglobulin, a 10% intravenous immunoglobulin as the first-line treatment of Kawasaki disease significantly reduced the fever duration (10 vs 13 hours, P = .022) among the responders, and the interval to adjunctive therapy for nonresponders (47 vs 49 hours, P = .035). There were no severe adverse events.
