Abstract:

Objective

To investigate the application value of echocardiography (UCG) combined with laboratory examination in predicting unresponsive Kawasaki disease (KD) intravenous immunoglobulin(IVIG) treatment.

Methods

The data of total of 164 children with KD admitted to the Children′s Cardiography Department of Chengdu Women and Children′s Central Hospital from September 2019 to September 2023 were collected.According to the sensitivity to IVIG treatment, the children were divided into the IVIG nonresponse group (n=82) and the IVIG response group (n=82). The UCG performance and laboratory examination indexes before treatment were compared between the two groups. Multivariate Logistic regression was used to predict the risk factors for IVIG non-response, and receiver operating characteristic (ROC)curve was drawn to evaluate the prediction efficacy.

Results

The proportion of coronary artery (CA)dilation in the IVIG non-response group was higher than that in the IVIG response group [37.80%(31/82),20.73%(17/82)], and the difference was statistically significant (χ2 = 5.773, P= 0.016). Tricuspid regurgitation (TR), alanine aminotransferase (ALT)>40 U/L, albumin (ALB)<35 g/L, D-Dimer>0.5 mg/L, neutrophil to lymphocyte ratio (NLR) >1.29, platelet (PLT) >420×109/L, platelet and lymphocyte ratio (PLR)>126.8 were independent risks factors for IVIG non-response [OR=19.136(95%CI: 3.634-100.756),1.016(95%CI:1.007-1.025),0.912(95%CI:0.835-0.996),1.780(95%CI:1.091-2.904),0.812(95%CI:0.681-0.969),1.014(95%CI:1.007-1.022),1.022(95%CI:1.006-1.037), all P<0.05]. The area under the ROC curve of TR combined with PLT was 0.850, the sensitivity was 63.41%, and the specificity was 95.12%. The area under the ROC curve of TR combined with ALT and PLT was 0.903, the sensitivity was 80.49%, and the specificity was 86.59%. The area under the ROC curve of TR combined with ALT, PLT, ALB, D-Dimer and PLR was 0.946, the sensitivity was 86.59%,and the specificity was 92.68%.

Conclusions

CA dilation, TR, ALT elevation, ALB reduction, D-Dimer elevation, NLR elevation, PLT elevation, PLR elevation, erythrocyte sedimentation rate elevation are highrisk factors for IVIG non-response in KD patients. UCG combined with laboratory testing provide a more accurate method for predicting IVIG non-response.
