    Abstract:
    BACKGROUND: Increased serum uric acid levels and vascular atherosclerosis are very common in diabetes. However, few studies focused on the relationship between serum uric acid and aortic or peripheral arterial stiffness in newly diagnosed diabetic patients. This study investigated the association between serum uric acid levels and carotid-femoral pulse wave velocity (cfPWV) or carotid-radial (cr) PWV in male patients with newly diagnosed type 2 diabetes mellitus (T2DM). METHODS: 106 male patients with newly diagnosed T2DM were recruited. cfPWV and crPWV as well as anthropometric parameters, blood pressure, serum uric acid, blood glucose, fasting insulin, C-reactive protein and blood lipids were measured. RESULTS: The subjects were divided into low uric acid (UA) subgroup and high UA subgroup according to uric acid median. cfPWV and crPWV were significantly higher in high UA subgroup. Serum uric acid significantly correlated with cfPWV (r = 0.533, P < 0.001), crPWV (r = 0.334, P = 0.001), waist circumference (r = 0.350, P < 0.001), waist-to-hip ratio (r = 0.254, P = 0.009), fasting insulin (r = 0.432, P < 0.001), HOMA-IR (r = 0.173, P = 0.042), fasting blood glucose (r = -0.271, P = 0.005), haemoglobin A1c (r = -0.202, P = 0.038), and HDL-cholesterol (r = -0.267, P = 0.006) after correction for age. Stepwise multiple regressions showed that the independent determinants of cfPWV were serum uric acid, age, C-reactive protein, HDL-cholesterol, and smoking status. And the independent determinants of crPWV were serum uric acid, age, diastolic blood pressure, and HDL-cholesterol. CONCLUSIONS: Serum uric acid is significantly associated with increased aortic and peripheral arterial stiffness in men with T2DM at the early stage.
