RESUMEN
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.

Various laboratory and patient-related factors can affect the measurement of hemoglobin A1c (HbA1c). We herein present the case of a diabetic patient with spuriously low HbA1c values on ion-exchange high-performance liquid chromatography (HPLC). Further investigations revealed that the patient was heterozygous for a rare Hb variant, namely Hb Iraq-Halabja (ß10 AlaâVal). This is the second report of this variant published in the literature. Clinicians should be aware of the limitations of HbA1c assays because inaccurate values may lead to the inappropriate management of diabetes. Unusual or discrepant HbA1c test results should prompt further investigations for potentially interfering factors, including rare Hb variants.
