Abstract

Purpose
: We evaluated the epidemiologic characteristics and incidence of coronary artery sequele of children with KD according to treatment.
Methods
: We retrospectively analyzed 506 medical records of children with KD, who were admitted at Daejeon St. Mary's Hospital from Jan. 1987 to Dec. 2000.
Results
: The mean annual incidence was 36.1±11.1 cases per year. There was a slightly higher occurrence in summer with no significant difference in monthly incidence. The mean age was 2.4＋1.7 years and 450 children(88.9%) were below four years of age. The male to female ratio was 1.7 : 1. When the 345 cases between 1987 and 1994 were divided into three groups according to treatment, incidences of the coronary abnormality(above grade II) of aspirin-treated(54 cases; 15.6%), divided-intravenous immunoglobulin(IVIG) treated(400-500 mg/day×4-5 days, 224 cases; 64.9%), and one-dose IVIG treated(2.0 g/day, 67 cases; 19.5%) groups were 8.3%, 6.0%, and 7.5%, respectively. Between 1995 and 2000, 143 cases were treated with only one-dose IVIG and 21 cases(14.7%) showed coronary artery abnormalities(grade I, 15 cases; grade II, two cases; and grade III, four cases). Among the 143 cases, 22 cases(15.1%) were retreated with IVIG and/or steroid pulse therapy. The incidence of coronary artery abnormality in this group was 50.0%. Incidences of cases in recurrence and among siblings were 0.6% and 0.4% respectively. There was no fatal case.
Conclusion
: In Daejeon, Korea, the epidemiologic feature of KD showed slight annual variations without monthly differences. The incidence of coronary abnormality with one-dose IVIG therapy was 14.7%. The nonresponse of this therapy was 15.1% with a coronary abnormality of 50.0%.
