Serum heart-type fatty acid-binding protein and platelet activating factor levels in Kawasaki disease and their clinical significance

Forty six children with Kawasaki disease (observer group) were classified as coronary artery lesions (CAL) subgroup (19 cases) and non-coronary artery lesions (NCAL) subgroup (27 cases)according to echocardiography; 50 healthy children served as control group.Serum heart-type fatty acidbinding protein (h-FABP), platelet activating factor (PAF), cardiac tropnin Ⅰ (cTnI) and creatine kinase isoenzyme MB (CK-MB) levels of all subjects were detected.The results showed that the h-FABP and cTnI levels and positive rate in observer group were higher those in control group (P ＜ 0.05 ), while there were no differences in CK-MB level and positive rate between two groups ( P ＞ 0.05 ).The h-FABP positive rate in observation group was higher than the positive rates of cTnI and CK-MB (P ＜0.05).The PAF level, PLT and polymorphonuclear neutrophil count in observer group were higher than those in control group ( P ＜0.05).The h-FABP and PAF levels in CAL subgroup were higher than those in NCAL subgroup (P ＜0.05).The results suggest that serum h-FABP and PAF can be used as diagnostic indicators for Kawasaki disease complicated with coronary artery lesions.
