Abstract

PURPOSE
Since the effect of intravenous immunoglobulin (IVIG) therapy in Kawasaki disease was reported in 1984, the combined therapy of IVIG & oral aspirin has been popular. In early period, the protocol of 400mg/kg/day for 3-5 days of IVIG had been used, but rescently, the protocol of 2g/kg/day single dose has been preferred. So authers performed a clinical study to compare th efficacies & side effects between 400mg/ kg/day for 5 days & 2g/kg/day single dose of IVIG plus oral aspirin (100mg/kg/ day).
METHODS
Seventy five patients who admitted to Eulji medical college hospital from January 1990 to July 1996 were evaluated retrospectively. Twenty nine patients (Group A) were treated with 400mg/kg/day for 5 days of IVIG plus aspirin (100mg/kg/day) and 46 patients (Group B) were treated with 2g/kg/day single dose of IVIG plus oral aspirin (100mg/kg/day).
RESULTS
1) The duration of fever after treatment was not significant difference between two groups (Group A, 25.5+/-30.3 days : Group B, 29.7+/-44.5 days P=0.7440) 2) The total admission days were significant difference between two groups (Group A, 9.9+/-0.4; Group B, 8.2+/-3.0, P=0.0308). 3) The incidence of side effects was not significant difference between two groups (Group A, 62%; Group B, 80%, P=0799). 4) The attack rate of coronary artery involvement was not significant difference between two groups (Group A, 34.5%; Group B, 26%, P=0.1198) 5) The case of re-treatment of IVIG due to relapse was not in Group A, but 5 in Group B (P=0.0661). 6) The mean platelet counts at admission were not difference between two groups (Group A, 434.4+/-17.2x103/mm3; Group B, 374.0+/-13.3x103/mm3, P=0.1449), but on the 7th hospital day, platelet counts were significant differnece between two groups (Group A, 531.9+/-16.5x103/mm3; Group B, 419.8+/-19.0x103/mm3, P=0.0066). 7) There was no significant difference in laboratory findings on admission and in the rate of coronary artery involvement between recurrent and non-recurrent cases of Group B. Conculusions : We conculuded that the protocol of 2mg/kg/day single dose of IVIG in Kawasaki disease may be have some benefits of shorter admission days and less coronary artery involvement, but the incidence of side effects and relapse rate might be less in the protocol of 400mg/kg/day of IVIG for 5 days.
