Abstract
Patients diagnosed with Kawasaki disease (KD) are at a high risk of developing coronary artery aneurysms. Intravenous immune globulin (IVIG) given in combination with aspirin is the standard of treatment for the prevention of coronary aneurysm. IVIG is recommended to be administered as a dose of 2 g/kg infused during 10 to 12 hours for the prevention of coronary aneurysms in KD; however, this does not always occur in practice. We aimed to investigate if an infusion time of <10 hours is associated with more coronary artery aneurysms than the recommended infusion time of 10 to 12 hours. Patients with a diagnosis of and treated for KD with IVIG at the University of Chicago Medicine Comer Children's Hospital were identified by drug use reports that included patients who received IVIG between September 2008 and August 2018. Data were collected though chart review and patients were divided into 2 groups based on duration of infusion (<10 hours and 10-12 hours). The primary outcome was the incidence of coronary artery aneurysm. The secondary outcome was the time to defervescence. The safety outcome was the development of renal dysfunction. A total of 70 patients were screened and 44 were included in the analysis. Coronary aneurysm occurred in 2 of 33 patients (6.0%) in the <10-hour group and no patients in the 10- to 12-hour group (p = 0.558). The median time to defervescence was 0.5 hours in the <10-hour group and 0.95 hours in the 10- to 12-hour group (p = 0.166). The incidence of acute kidney injury was 6% (2 of 33 patients) in the 10-hour group and 9.1% (1 of 11 patients) in the 10- to 12-hour group (p = 0.588). All incidences of coronary artery aneurysm occurred in the patients who received IVIG with an infusion time of <10 hours. The incidence of acute kidney injury was numerically higher in the 10- to 12-hour group. Based on the recommendations in the American Heart Association KD guideline, our internal hospital policy, and our results, we recommend the infusion of IVIG be administered at a rate of 10 to 12 hours.
