ALB and type 2 diabetes mellitus: We evaluated the relationship between serum VD and CAN in patients with type 2 Diabetes Mellitus (T2DM) in early and advanced stages of DKD.<h4>Methods</h4>Seventy-six T2DM patients, 28 in early DKD stage (urine albumin to creatinine ratio (UACR)): 30 to 299 mg/g - group 1), and 48 in advanced DKD stage (UACR ≥300 mg/g - group 2), participated.<h4>Results</h4>In group 1, prevalence of CAN was 46% versus 75% in group 2 (p=0.01).
