Abstract
BACKGROUND: This study was to investigate the epidemiologic trends of Kawasaki disease (KD) and coronary arterial lesions (CALs) in Shanghai from 2008 through 2012. METHODS: Data were collected by using the network of the KD research group established during the first survey in Shanghai to conduct the third survey, covering the period from 2008 through 2012. Clinical records of 2304 patients with acute KD were retrospectively reviewed. Epidemiologic features of KD were investigated. Univariate and multivariate analyses were performed to identify the risk factors for CAL in patients with KD. The data were compared with the previous 2 surveys covering the periods from 1998 to 2002 and 2003 to 2007, respectively. RESULTS: The average incidence of KD was 30.3 to 71.9 per 100,000 children aged 0-4 years from 2008 through 2012. Age at onset ranged from 32 days to 11.7 years (median: 2.3 years). The occurrence of KD was more common in summer and spring. A total of 365 (15.9%) cases developed CAL defined as ectasia or aneurysm. Male, age ≤ 1 year, intravenous immunoglobulin (IVIG) unresponsiveness, a smaller administrative dosage and the delayed administration of IVIG (>10 days) were independent risk factors for CAL. The occurrence of CAL seemed less frequent in patients who received IVIG within 5 days after onset of illness. CONCLUSIONS: The incidence of KD in children has increased over time, and the development of CAL decreased in the past 5 years in Shanghai. Earlier treatment with IVIG (<5 days) was associated with reduced CAL among patients with KD.
