Abstract

PURPOSE
This single-center study was conducted to assess the changes in epidemiological and clinical characteristics and outcomes of patients with Kawasaki disease (KD) over the past 7 years.
METHODS
This retrospective study included 135 children with KD, admitted to Chungnam National University Hospital, Daejeon, between 2004 and 2005 (group A, n=53) and between 2011 and 2012 (group B, n=82). Medical records were reviewed to obtain information regarding the presenting signs and symptoms, demographic characteristics, and laboratory and echocardiographic findings associated with KD.
RESULTS
The hospital admission date after onset was significantly earlier in group B than in group A (P=0.008). The proportion of patients with incomplete KD was 45.3% and 65.9% in group A and B, respectively (P=0.018). The number of pretreatment coronary artery lesions (CALs) were significantly lesser in group B than in group A. (10/53 vs. 5/82, P=0.021). No significant differences was observed in the incidence of CALs at discharge, febrile phase duration, hospital stay duration, incidence of retreatment, and intravenous immunoglobulin dose between 2 groups. The total febrile phase was shorter in patients with incomplete KD than in those with complete KD in both groups.
CONCLUSION
The proportion of incomplete KD has become higher. Furthermore, early admission and management of patients with KD may be related to increased incomplete KD and decreased CALs. Therefore, we believe that a diagnostic strategy for incomplete KD should be established regardless of the presence of coronary lesions.
