Relationship between peripheral artery disease and combined albuminuria and low estimated glomerular filtration rate among elderly patients with type 2 diabetes mellitus.

This study aimed at investigating the combined effects of albuminuria and reduced estimated glomerular filtration rate (eGFR) on peripheral artery disease (PAD) among elderly patients with diabetes. A total of 236 subjects were cross-classified into four groups according to the presence or absence of albuminuria (urinary albumin creatinine ratio (ACR) ≥ 30 mg/g) and low eGFR (<60 mL/min/1.73 m²). Cardiovascular risk factors and the ankle-brachial index (ABI) were also assessed. After multivariate adjustment using logistic regression analysis, the odds ratios (OR) for prevalent PAD related to albuminuria with preserved eGFR, normoalbuminuria with low eGFR and albuminuria with low eGFR compared to normoalbuminuria with preserved eGFR were 1.10 [95% confidence interval (CI) = 0.43-2.79], 3.14 (95% CI = 1.20-8.22) and 3.87 (95% CI = 1.72-8.72), respectively. In conclusion, in elderly patients with type 2 diabetes, both normoalbuminuria with low eGFR and albuminuria with low eGFR are associated independently with PAD.
