Comparison of Clinical Features and Inflammatory Markers between Kawasaki Disease Shock Syndrome and Kawasaki Disease without Shock: A Meta-Analysis

Since the shock is not a common symptom of KD, it is often misdiagnosed at the beginning of the pathogenesis of KDSS. The language searched was only Chinese and English. Data from the articles were screened and extracted for meta-analysis using Stata16.0 software. A total of 9 cohort studies, including 1231 patients, were included in this meta-analysis. The results of meta-analysis showed that the age of the children in the KDSS group was higher than that in the KD group without shock, and the difference was statistically significant (SMD = 1.15, 95% CI (0.52, 1.78), P < 0.05 ); the CRP content in the KDSS group was higher than that in the KD group without shock, and the difference was statistically significant (SMD = 1.99, 95% CI (0.72, 3.26), P < 0.05 ); the albumin content in the KDSS group was lower than that in the KD group without shock, and the difference was statistically significant (SMD = −1.26, 95% CI (−1.85,−0.67), P < 0.05 ); the AST content in the KDSS group was higher than that in the KD group without shock, and the difference was statistically significant (WMD = 25.95, 95% CI (15.14, 36.75), P < 0.05 ); the difference had statistical significance (RR = 3.50, 95% CI (2.30, 5.32), P < 0.05 ); meta-analysis results of type of KD, fever duration, WBC count, ESR, ALT, and other outcome measures showed that there was no significant difference between KDSS and KD without shock ( P > 0.05 ). Compared with KD without shock, children with KDSS are older and have a higher incidence of coronary artery disease, serum CRP, and AST, but albumin is lower than KD without shock. According to these characteristics, it may be helpful for the early identification of KDSS.
