Association of uric acid and glucose disposal rate value in euglycemic Chinese subjects

Abstract

Background: We aimed to examine the relationship between serum uric acid (SUA) levels and glucose disposal rate value (M value) evaluated by hyperinsulinemic euglycemic clamp technique in euglycemic Chinese subjects.Methods: There were 19 non-diabetic Chinese subjects included in this study. The participants accepted physical examination, laboratory examination and standardized questionnaire. Insulin resistance was evaluated by M value. Some other indices were also calculated by data obtained from 3-hour oral glucose tolerance test (OGTT). Subjects were divided into two groups based on the median of SUA levels.Results: The level of systolic blood pressure (SBP) (P=0.035), waist circumference (P=0.009), waist-to-hip ratio (P=0.004), Chinese visceral adiposity index (CAVI) (P=0.028), weight (P=0.01), serum creatinine (Cr) (P=0.05) and the percentage of drinking habits (P=0.03) were all significantly increased in high SUA group. The level of M value and high-density lipoprotein cholesterol (HDL-c) were significantly decreased in high SUA group (P=0.041 for M value and P=0.09 for HDL-c). There were no significant differences between those indirect insulin resistance indices and SUA. In addition, the SUA levels were inversely correlated with M value (r=-0.666, P=0.002) and HDL-c (r=-0.619, P=0.005), positively correlated with waist circumference (r=0.615, P=0.005), CVAI (r=0.630, P=0.004), SBP (r=0.521, P=0.022) and Cr (r-0.550, P=0.015) levels. Analysis of stepwise multiple regression showed the independent association between SUA and M value in both male and female euglycemic subjects.Conclusions: There is a significant correlation between SUA levels and glucose disposal rate value in euglycemic Chinese subjects, which suggested that UA played an important role on insulin resistance even in those non-diabetic subjects
