Key clinical point: Serum level of 25-hydroxyvitamin D (25[OH]D) was inversely associated with albuminuria as an indicator of diabetic nephropathy in patients with type 2 diabetes mellitus (T2D), with the prevalence of macroalbuminuria increasing when the serum 25(OH)D level was <20 ng/mL.
Major finding: A strong negative association was observed between the serum 25(OH)D level and severity of albuminuria ( r, −0.257; P < .001), with the prevalence of vitamin D deficiency being 61.8%, 33.3%, and 24.0% in patients with macroalbuminuria, microalbuminuria, and normoalbuminuria, respectively.
Study details: This was a cross-sectional study including 200 patients with T2D, of which 100, 66, and 34 had normoalbuminuria, microalbuminuria, and macroalbuminuria, respectively.
Disclosures: This study was supported by Shiraz University of Medical Sciences, Iran. The authors declared no competing interests.
