Clinical Trial: Prevention of Coronary Aneurysms in Kawasaki Syndrome

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title:

Brief Summary: To test the efficacy of intravenous gamma globulin (IVGG) in preventing coronary artery aneurysms in children with Kawasaki Syndrome.

Detailed Summary:

BACKGROUND:

Kawasaki Syndrome is an acute febrile illness that occurs predominantly in previously healthy young children. It is of unknown etiology and was first described in Japan in 1967. The illness carries an acute mortality rate of approximately 3 percent. The Centers for Disease Control defines Kawasaki Syndrome as a fever lasting five or more days for which no explanation can be found. Patients also must have at least four of the following symptoms: bilateral conjunctival infection; infected or fissured lips, pharynx, or a 'strawberry tongue'; erythema of the palms or soles, or edema of the hands or feet, or generalized or periungual desquamation; rash; and cervical lymphadenopathy.

Coronary artery aneurysms occur in 15-20 percent of children with the illness. In the past, no treatment had been shown to be effective in preventing this complication. Investigators in Japan began to use IVGG to reduce the aneurysm formation. Preliminary results showing the usefulness of this therapy led to a multicenter trial in Japan in which 400 mg/kg/day of IVGG were given for five days to children also receiving aspirin for the condition. Results of the Japanese trial showed that within 29 days of the onset of the disease, coronary artery dilatation had developed in 42 percent of the aspirin-treated children and in 15 percent of the IVGG and aspirin-treated children.

DESIGN NARRATIVE:

Phase I was randomized, unblinded and stratified by age, sex, and center. Subjects were randomized to receive either 80 to 120 mg/kg/day of aspirin through day 14 of illness, subsequently reduced to 3 to 5 mg/kg/day as a single daily dose or to 400 mg/kg/day of intravenous gamma globulin for four consecutive days plus aspirin as above.
