Abstract

Background: We measured the concentrations of the adipocytokines vaspin and visfatin in obese Chinese children. Furthermore, we studied the correlation of these adipocytokines with early-onset metabolic and vascular sequelae among these children. Methods: A total of 244 children (160 obese and 84 lean) were included in this study. Vaspin and visfatin were detected using enzyme-linked immunosorbent assays. We also assayed other metabolic and cardiovascular parameters. The associations of serum vaspin and visfatin concentrations with metabolic and cardiovascular parameters were determined. Results: We found a significant elevation in the concentrations of vaspin and visfatin in obese children compared to the concentrations in lean children. Additionally, we found a significant positive correlation between visfatin and vaspin levels, as well as inflammatory cell infiltration and markers of endothelial activation, but these factors did not affect insulin resistance in obese children. Multiple regression analyses confirmed that vaspin is the strongest predictor of higher tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), angiotensin-2 (Ang-2), vascular cellular adhesion molecule-1 (VCAM-1), and E-selectin levels. We also found a significant association between visfatin and Ang-2, IL-6, VCAM-1, and E-selectin levels. Conclusion: The adipocytokines vaspin and visfatin are significantly interrelated, and both adipocytokines play a role in vascular endothelial function and inflammation.
