ABSTRACT
Objective To investigate the change of leptin,nitric oxide (NO) and interleukin-6 (IL- 6) levels in serum of children with Kawasaki disease (KD) and the possible relationship between leptin,NO and IL-6 levels,explore the role of leptin,NO and IL-6 in the pathogenesis of KD.Methods Fourty-five children with KD were studied.Twelve of them had coronary artery lesions and 33 had non-coronary artery lesions;thirty healthy children and 18 children with juvenile idiopathic arthritis or Henoch-Scholeion purpuru were enrolled as control subjects.Serum was collected from each patients during acute stage of KD and remission.Leptin,NO and IL-6 contents were detected by radioimmuno-assay and spectrophotometry and enzyme-linked immunoserbent assay.Meanwhile,C-reactive protein (CRP) were examined.Results ① The concentrations of serum leptin,NO,IL-6 and CRP in children with KD were significantly higher in the acute stage of KD than those at clinical remission and those of the normal control group (q=26.24,25.23; 21.38,31.30;35.37,33.68;16.32,15.66;P<0.01,respectively).No significant differences in serum leptin, IL-6 and CRP were found between the clinical remission group and the normal control group (q=1.02,1.04, 0.61,P>0.05,respectively);The concentrations of serum NO were significantly higher at clinical remission group than those of the normal control group (q=11.31,P<0.01).② There was no significant difference in the concentrations of serum leptin,IL-6 and CRP at the acute stage of KD than those in patients with and without coronary artery lesions (q=1.17,1.92,1.60,P>0.05).The concentrations of serum NO were significantly higher at the acute stage of KD with coronary artery lesions than those of KD without coronary artery lesions (q=6.91,P<0.01).③ The concentrations of serum leptin in children with juvenile idiopathic arthritis or Henoch-Scholeion purpura were signifietantly higher than those of the normal control group (t=13.26,P< 0.01).No significant differences in serum leptin were found between children with juvenile idiopathic arthritis or Henoch-Seholeion purpura and children with KD (t=1.28,P>0.05).④ Correlation was found between serum leptin values and levels of the following parameters (P<0.01);NO (r=0.69),IL-6 (r=0.55),CRP (r=0.42).However,there were no associations between leptin and leukocytes (r=0.21,P>0.05) or serum albumin level (r=-0.24,P>0.05).Association was found between serum NO and IL-6 (r=0.45,P<0.01)or CRP(r=0.49,P<0.01).Conclusion These results suggest that leptin,NO and IL-6 may have a role in the immunoinflammatory process of KD,especially in the acute phase.Further in vivo and in vitro studies are needed to establish the roles of leptin,NO and IL-6 in the pathogenesis of KD.
