Abstract:
Objective Increased serum uric acid level is associated with type 2 diabetes (T2DM) through the mechanism of oxidative stress.As the rate-limiting enzyme in the degradation of purines in humans,xanthine oxidoreductase (XOR)catalyzes the final two reactions of purine catabolism,oxidizing hypoxanthine to xanthine,and xanthine to uric acid.The aim of this study is to investigate the association between serum XOR activity and T2DM.Methods A total of 270 patients with T2DM and 140 age-and-gender-matched health controls were enrolled in the study.The clinical examinations such as weight and height were conducted in the morning after an overnight fast.Serum XOR activity and other biochemical parameters like triglyceride,total cholesterol,high density lipoprotein cholesterol,fasting plasma glucose and uric acid levels were measured.Results Serum XOR activity was significantly elevated in T2DM patients compared with that in the controls (31.2 ± 8.91 vs 4.6 ± 0.91 U/L,P ＜0.01).Serum XOR activity was significantly elevated in T2DM patients complicated with lower extremity arterial disease compared to that in patients without lower extremity arterial disease (42.1 ± 8.43 vs 23.7 ± 5.31 U/L,P ＜ 0.01).Conclusion High XOR activity plays an important role in onset and development of T2DM.
