Histopathologic and coronary angiographic assessment of effectiveness of aspirin or aspirin-and-gammaglobulin in Kawasaki disease.

Abstract

Coronary angiography and right ventricular endomyocardial biopsy were performed in 36 children during convalescence (days of illness 23-86; mean = 41.5 days) following acute Kawasaki disease. Treatment of the acute stage was not randomized; it consisted of aspirin alone in 14 subjects (during the years 1980-88), and gammaglobulin and aspirin in 22 subjects (1984-91). The dosage of aspirin was 30 mg/kg orally during the acute febrile stage and 5-10 mg/kg orally after lysis of fever. The dosage of gammaglobulin was 200 mg/kg x 5 days in 19 patients, 200 mg/kg x 3 days in one patient, 200 mg/kg x 1 day + 400 mg/kg x 4 days in one patient and 200 mg/kg x 4 days + 400 mg/kg x 4 days in one patient. Among the 14 patients treated with aspirin alone, large coronary aneurysms were noted in four, moderate aneurysms in three and transient aneurysms in one. Among 22 patients treated with gammaglobulin, only five had aneurysms and these were transient. The histopathological (HP) score based on myocardial disarrangement, degeneration and hypertrophy; interstitial edema, large mononuclear cell infiltration and fibrosis; and endocardial abnormalities was higher in the aspirin group than in gammaglobulin group. Moderate to severe HP changes were noted in five subjects in the aspirin group, while moderate HP changes were found in only two subjects in the gammaglobulin group. Gammaglobulin therapy not only reduced the incidence of the coronary arterial lesions but also reduced the severity of myocardial damage from moderate or severe to mild in Kawasaki disease.
