Abstract
Background Hyperinsulinemic euglycemic clamp is the gold standard to evaluate the insulin sensitity, but it is too complicated and expensive to use in clinic.We tried to find an alternative indicator to reflect insulin sensitivity.To evaluate the association between the four adipokines, adiponectin, leptin, resistin and tumor necrosis factor-α (TNF-α) with insulin sensitivity, we used a hyperinsulinemic euglycemic clamp to test insulin sensitivity in Chinese patients with obesity and type 1 or type 2 diabetes mellitus versus controls.Methods In this parallel control study, we tested insulin sensitivity using a hyperinsulinemic euglycemic clamp in different groups, then examined levels of adiponectin, leptin, resistin and TNF-α in serum, and the relationship between the different adipokines and glucose disposal rate (M value), as well as insulin sensitivity index (M value/insulin, M/I),which are the "gold standard" indices of insulin sensitivity.Results There were significant differences in mean leptin values in the four adipokines from the four different groups (P<0.001; comparison of the variation between different groups was analyzed by variance analysis).Compared to controls (using multiple comparison two-way Dunnett t test), only the leptin level showed significant differences in the four adipokines from the four different groups at the same time (P <0.001).The association analysis between the different adipokines and M or M/I values also showed that only leptin negatively correlated with M (r=-0.64, P <0.001) or M/I values (r=-0.56, P<0.001); there was no relationship between the other three adipokines and M or M/I values.Conclusion Only leptin was associated with M or M/I values.Therefore, leptin might be one of the predictive factors of the degree of insulin resistance and risk of the accompanying disease.关键词
