Abstract
Objective To investigate the relationship between the change of circulating endothelial cell (CEC) level and coronary artery lesion (CAL) of Kawasaki disease (KD),and to further explore the method for early diagnosis of KD.Methods Thirty KD children were recruited for study,including 23 children with complete type of KD and seven children with incomplete KD.According to the results of echocardiography,the KD group was divided into CAL group (9 cases) and non-coronary artery lesion (NCAL)group (21 cases).Ten healthy children were enrolled as control group.Double-blind and controlled trial was conducted,and Hladovec method was applied for CEC counting.Results The CEC level was ( 1.09 ±0.60) × 107/L in KD group,which was higher than that of control group [ (0.38 ±0.14) × 107/L],and the difference was statistically significant ( t =2.85,P ＜ 0.01 ).The CEC level in the CAL group [ ( 1.84 ± 0.24) × 107/L] was higher than that of the NCAL group[ (2.01 ±0.38) × 107/L],and the difference was statistically significant ( t =2.24,P ＜ 0.05 ).The CEC level was ( 1.16 ± 0.63 ) × 107/L in the complete type of KD group and (0.83 ± 0.45 ) × 107/L in the incomplete KD group,which showed no significant difference between the two groups ( t =1.86,P ＞ 0.05 ).Condusion CEC level was elevated significantly in the acute phase of KD.The CEC level in CAL group was higher than that of NCAL group in acute phase.CEC level detection may be helpful for the early diagnosis of KD.
