Abstract: Objective:To compare and analyze the ultrasonic images between intestinal involvement in Kawasaki disease (IIKD) and abdominal type allergic purpura (ATAP), so as to improve the understanding of IIKD.Methods:From July 2014 to January 2020, the ultrasonographic images of 21 children with IIKD and 24 children with ATAP in Tianjin Children′s Hospital were collected and analyzed.Results:Univariate analysis showed that there were significant differences between IIKD group and ATAP group in non stratified thickening of intestinal wall, decreased echo of serosa and adjacent mesentery (irregular shape), thickening of peripheral fat tissue and abnormal shape of adjacent lymph nodes (all P<0.05); Multivariate analysis showed that decreased echo of serosa and adjacent mesentery (irregular shape) were independent influencing factors of IIKD. The area under ROC curve was 0.914(95% CI=0.819-1.000, P<0.001). The sensitivity and specificity of IIKD were 95.2% and 87.5%, respectively. Conclusions:The ultrasonographic images of intestinal involvement in IIKD and ATAP have certain specificity. Decreased echo of serosa and adjacent mesentery (irregular shape) can effectively distinguish IIKD and ATAP.
