BackgroundThe aim of our study was to evaluate the long-term impacts of Kawasaki disease on our patients regarding coronary involvement demographic characteristics, treatment regimens, and clinical course.MethodsOur study included 104 patients diagnosed and hospitalized with Kawasaki disease in our center, from January 2004 to January 2019. In our study, patients were divided into three groups according to coronary artery involvement. Patients in group 1 had no echocardiographic findings, while the ones in group 2 had coronary artery dilatation and ones in group 3 had coronary artery aneurysm (CAA).ResultsAmong 104 patients, the median age was 9.15 (3.0-22.0) years, and 61 of the patients were male while 43 of the patients were female. With a wide range of 1.50-16.50 years of follow-up time, the median diagnosis age of our patients was 31 months (3.0-164.0). Fever duration (median day 10 (5-21), p = 0.025) was statistically significantly higher in group 3. Blood C-reactive protein (CRP) levels, white blood cell (WBC) counts, and neutrophil counts were significantly higher in group 3. There was a statistically significant difference between patients in group 3 and group 2 in which the lowest strain deformation values were in the patients of group 3. In contrast to group 1, the time for initiation of IVIG therapy is significantly prolonged both in group 2 (median: 9.5 days, p = 0.028) and group 3 (median: 10 days, p = 0.036).DiscussionIn our study, serum CRP levels, WBC count, and neutrophil count were higher in patients with coronary artery abnormalities, in agreement with the previous studies. In the light of our results, we consider that the most important determining factor for the development of coronary artery aneurysm is the time of intravenous immunoglobulin (IVIG) administration.
