Abstract

We measured serum concentrations of advanced glycation endproducts (AGEs) in patients with type 2 diabetes, to elucidate the mechanisms underlying the elevated serum concentrations of AGEs and to clarify the relationship between serum AGE concentrations and the development of microangiopathy and macroangiopathy. Serum AGEs were significantly higher in diabetic patients than in age-matched control subjects (p < 0.0001). In diabetic patients, serum AGEs were positively correlated with HbAlc (r = 0.47, p < 0.0001), urinary albumin excretion (UAE) (r = 0.42, p < 0.0001), diabetes duration (r = 0.31, p = 0.0030), and fasting plasma glucose (r = 0.34, p = 0.0010). Multiple regression analysis disclosed that only the HbAlc and UAE levels independently correlated with serum AGE levels. Serum AGEs in diabetic patients with progressive retinopathy and overt nephropathy were significantly higher than in those with less severe retinopathy and nephropathy. Serum AGEs were significantly higher in the diabetic patients with coronary heart disease (CHD) than in those without CHD. These results suggest that the HbAlc and UAE levels are independent risk factors for increased serum AGE concentrations in type 2 diabetic patients, and that higher serum AGE concentrations are associated with increased severity of diabetic retinopathy and nephropathy. Serum AGE concentrations may be a useful marker not only for the severity of diabetic microangiopathy but also for the development of CHD in patients with type 2 diabetes mellitus.
