Abstract：Objective:To explore the changes and clinic significance of plasma matrix metalloproteinase-9(MMP-9) and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in children with Kawasaki disease(KD).Method:Forty two children with KD in our hospital from January 2015 to January 2016 were collected and divided into two groups according to the results of echocardiography,the coronary artery lesion(CAL) group(n=18) and the non-coronary artery lesion(NCAL) group (n=24).Thirty febrile children with respiratory tract infection and twenty healthy children in the same period were chosen as the control group.The plasma MMP-9 and NT-proBNP protein levels were measured respectively.Result:The plasma MMP-9 and NT-proBNP levels in the acute phase of KD patients were all higher than those in the two control group(P<0.01),and which were significantly higher in the CAL group than in the NCAL group,the differences were statistically significant(P<0.05 ).The plasma MMP-9 and NT-proBNP levels in remission stages were siginificantly lower after treatment,and the protein level of NT-proBNP in the CAL group was still higher than that of the NCAL group,the differences were statistically significant(P<0.05).There was a positive correlation between plasma MMP-9 and NT-proBNP levels in the acute phase of KD(r=0.57,P<0.05).Conclusion:The plasma MMP-9 and NT-proBNP levels are closely related to KD cardiovascular damage,combined detection of them may have critical value for the early diagnosis of KD and the prediction of CAL.
