Abstract:
Objective To explore the expression levels and clinical significance of serum Gasdermin D(GS-DMD)and angiotensin converting enzyme 2(ACE2)in children with Kawasaki disease(KD).Methods A to-tal of 90 children with KD treated in the hospital from January 2020 to January 2022 were collected as KD group.According to whether the children with KD had coronary artery lesions(CAL),the KD group was di-vided into CAL group(32 cases)and non-CAL group(58 cases),and 50 children with fever due to acute re-spiratory infection admitted to the hospital during the same period were selected as fever control group.An-other 50 children with oblique inguinal hernia who underwent elective surgery in the same period were selected as the control group.Serum GSDMD and ACE2 levels were detected by enzyme-linked immunosorbent assay.The correlation between serum GSDMD,ACE2 and clinical indicators was analyzed by Pearson correlation.Multivariate Logisitic regression was used to analyze the influencing factors of CAL occurrence in KD pa-tients.The diagnostic value of serum GSDMD and ACE2 for CAL in children with KD was analyzed by receiv-er operating characteristic(ROC)curve.Results The serum GSDMD and ACE2 levels in KD group were higher than those in fever control group and control group,and the differences were statistically significant(all P＜0.05).Compared with the non-CAL group,the fever duration,gamma globulin treatment time,erythro-cyte sedimentation rate,platelet count,C reactive protein,GSDMD and ACE2 levels of KD children in the CAL group were significantly higher,while the blood sodium and albumin were significantly lower,with statistical significance(all P＜0.05).The results of Pearson correlation analysis showed that serum GSDMD and ACE2 levels in KD group were positively correlated with fever duration,gamma globulin treatment time,erythrocyte sedimentation rate,platelet count and C reactive protein(all P＜0.05),and negatively correlated with blood sodium and albumin(all P＜0.05).Multivariate Logistic regression analysis showed that the increase of ser-um GSDMD and ACE2 was an independent risk factor for the development of CAL in KD children.ROC curve analysis results showed that the area under the curve(AUC)and 95％CI of the combined detection of serum GSDMD and ACE2 for CAL in KD children were 0.918(0.868-0.949).The AUC and 95％CI of serum GS-DMD and ACE2 were significantly higher than that of serum GSDMD and ACE2[0.838(0.789-0.887)and 0.865(0.811-0.912),respectively],and the differences were statistically significant(Z=5.116,4.217,all P＜0.05).Conclusion The combined detection of serum GSDMD and ACE2 has high diagnostic value for CAL in children with KD.
