Abstrakt:	Diabetes mellitus is a metabolic disease that is characterized by chronic hyperglycemia. Type 2 diabetes is a global health problem and leading to many dangerous complications. Diabetic nephropathy is a significant microvascular complication resulting from diabetes mellitus that is affecting up to 50% of patients with end stage renal disease. Vitamin D deficiency may occur due to many different factors and is associated with many serious diseases as diabetic nephropathy. To investigate the 25-hydroxyvitamin D deficiency and predictive factors in patients with diabetic nephropathy in type 2 diabetes mellitus. One hundred type 2diabetic patients were divided into two groups according to Alb/creat ratio to diabetic patients with and without nephropathy and 50 non-diabetic controls. We measured the serum 25-hydroxyvitamin D levels in all the study populations. The mean serum level of 25 (OH) D was significantly decreased in patients with diabetic nephropathy (13.41±4.99 ng/ml, P=0.002). There was a significant correlation with vitamin D deficiency and the patients residency and also a significant positive correlation with eGFR (r = 0.317, P = 0.025) and a significant negative correlation with Alb/creat Ratio(r = -0.323, P = 0.022). The significant best-fitting predictors of vitamin D deficiency were living in rural area (OR=4.030, P < 0.021) and eGFR < 60 (OR=5.412, P < 0.034). In conclusion, vitamin D deficiency is prevalent in patients with diabetic nephropathy living in rural areas. Low eGFR < 60, Alb/creat ratio more than 30 mg/24h and HbA1c > 9 could be considered as predictive factors of vitamin D deficiency in these patients.
