Expression of Circulating Vitamin D, VDBP, and Vitamin D Receptor in Diabetic Nephropathy patients

What is it about?

- Vitamin D receptor expression was elevated in normoalbuminuria group of type 2 diabetes patients compared to micro- and macroalbuminuria groups - Serum vitamin D binding protein (VDBP) levels were significantly elevated in all patient groups (i.e. normo-, micro, and macroalbuminuria) - Serum VDBP levels, HBA1c, and BMI could predict albuminuria in diabetic nephropathy patients studied.

Why is it important?

The study findings suggest a potential role of vitamin D metabolic players in diabetic nephropathy, with a special concern regarding serum VDPB as a putative predictor of DN severity in type 2 DM Saudi patients.
