Clinical Trial Summary

Kawasaki disease (KD) is an acute multi-system vasculitis syndrome of unknown etiology occurring mostly in infants and children younger than 5 years of age. In developed countries, it is the leading cause of acquired heart disease in children. However, KD remains a mysterious disease.

Single high dose intravenous immunoglobulin (IVIG, 2gm/kg) and aspirin are standard treatment for KD. Aspirin have been prescribed in treatment of KD for decade even earlier than usage of IVIG. High dose aspirin mainly act as anti-inflammation, while low dose aspirin as anti-platelet. IVIG may play most of the role of anti-inflammation in acute stage of KD. Hsieh et al. reported that KD without high dose aspirin had the same treatment response after IVIG. Therefore it is still unclear about the necessarily of high dose aspirin in acute stage of KD.

This study was conduct to investigate the role of high dose aspirin in acute stage of KD via a multi-center randomized control trail, and we plan to achieve the followings till year 2017:

1. Enroll 300 KD patients from multiple medical centers . Randomize group patients as group 1: with high dose aspirin (more than 30/mg/kd/day) until fever subsided and shift to low dose aspirin (3-5mg/kg/day, N=150); and group 2: without high dose aspirin during acute febrile stage, only use low dose aspirin (N=150).

2. Compare data including fever days, admission duration, laboratory data (CBC/DC, GOT/GPT, BUN/Cr, Alb, ESR, CRP, 2D echo), IVIG treatment response and CAL formation rate (followed at least 1 year).


Clinical Trial Description

All subjects are children who fulfilled the criteria for KD and who are treated with IVIG at each hospital after informed contents are obtained. The patients are initially treated with a single dose of IVIG (2 g/kg) during a 12-hour period.

Principal clinical features of KD that occur in the acute stage within 5 days of the onset of fever will be recorded. After the informed content from the parents, PB samples will be obtained before IVIG treatment (pre-IVIG, KD1), within 3 days after complete initial IVIG treatment (post-IVIG, KD2) as the acute stage samples and then 1 month, 6 month and 12 month followed-up as subacute/convalescent stage samples. CAL was defined as the internal diameter being at least 3 mm of the coronary artery (4 mm if the subject was over the age of 5 years) or the internal diameter of a segment at least 1.5 times as large as that of an adjacent segment by echocardiogram.

High dose aspirin will be given (> 30 mg/kg/day) until the fever subsided at group 1 randomly. After fever subside (<38C, for 48 hours) low-dose aspirin (3-5 mg/kg/day) will be prescribed for all patients until all signs of inflammation resolved in both group 1 and 2. ;
