An Analysis of the Relationship Between Ankle–Brachial Index and Estimated Glomerular Filtration Rate in Type 2 Diabetes

Chronic kidney disease (CKD) is significantly associated with peripheral arterial disease (PAD) in some studies, but data on the association of the risk of PAD across a broad range of kidney function in patients with type 2 diabetes are limited. Between October 17, 2013 and February 7, 2015, all consecutive outpatients with type 2 diabetes underwent ankle-brachial index (ABI) examination. We investigated the association of estimated glomerular filtration rate (eGFR) and albumin-to-creatinine ratio (ACR) with the risk of PAD. A total of 1254 patients were cross-classified into 12 groups based on ACR category (normoalbuminuria, microalbuminuria and macroalbuminuria) and eGFR stage (≥90, 60–89, 30–59 and <30 mL/min/1.73 m2). Logistic regression analysis was used to investigate the association of eGFR and ACR with PAD. Within each ACR category, a lower eGFR stage was associated with PAD. Similarly, within each eGFR group, a higher ACR category was also associated with PAD. The OR for PAD was highest in patients with eGFR <30 mL/min/1.73 m2 and macroalbuminuria (OR 14.42, 95% CI 4.60 to 45.31) when compared with the reference group of subjects with eGFR ≥90 mL/min/1.73 m2 and normoalbuminuria. Our study found that cross-classification of eGFR with ACR revealed a more comprehensive association with risk of PAD than eGFR or ACR alone.

Introduction: Simple renal cysts (SRCs) are the most common acquired cystic kidney disease, but the relationship between SRCs and renal function has not been clarified in patients with type 2 diabetes mellitus (T2DM).Methods: A retrospective study was conducted to analyze the clinical features of renal cysts and ultrasound data of the kidney in 4,304 patients with T2DM.Results: The prevalence of SRCs in patients with T2DM was 21.1%. Compared to patients with no SRCs, patients with SRCs had worse renal function (estimated glomerular filtration rate: 108.65 ± 40.93 vs. 92.38 ± 42.1 ml/min/1.73 m2, p < 0.05). After adjusting the confounders, SRC was related to estimated glomerular filtration rate in patients with T2DM [odds ratio = 1.49, 95% confidence interval (1.24, 1.79), p < 0.01]. Age, gout, proteinuria, cerebrovascular disease (CVD), and increased serum phosphorus levels were associated with SRCs in patients with T2DM.Conclusion: SRCs are associated with worse renal function in patients with T2DM. More attention should be paid to gout, proteinuria, CVD, serum phosphorus levels, and renal function in T2DM patients with SRCs.

Toe Brachial Index

We enrolled 1461 Taiwanese type 2 diabetic outpatients with ankle-brachial index (ABI) and toe-brachial index (TBI) examinations, excluding participants with history of stroke, end-stage renal disease, malignancy, acute myocardial infarction, amputation, and overt calcification of the lower limbs (ABI >1.3). Ankle-brachial index values <0.9 were found in 2.8% of the patients and 5.7% had TBI <0.6. Estimated glomerular filtration rate (eGFR; 90 ± 33 mL/min per 1.73 m2) obtained from 473 patients correlated significantly with both ABI and TBI. Progressive eGFR decline was observed in 419 participants with normal ABI and TBI, 35 with normal ABI but low TBI, and 19 with low ABI and normal or low TBI ( P for trend <.001). After adjusting for confounding factors, age and eGFR were significantly associated with TBI and ABI. Low eGFR is associated with peripheral arterial disease in type 2 diabetes with mild to moderate renal insufficiency.
