Abstract

Background: 25-(OH) vitamin D (VD) deficiency has been described as potential risk factor for the development of diabetes in many epidemiological studies. 25-(OH) VD deficiency and insulin resistance associated with this deficiency are common findings in patients with type 2 diabetes mellitus. The objective of this study is to evaluate the relationship between 25-(OH) VD levels and microalbuminuria. Methods: The patients with type 2 diabetes mellitus aged between 40 and 65 years, who were admitted to the diabetes outpatient clinics of our hospital, were evaluated in two different groups. The first group consisted of 119 patients with insufficient 25-(OH) VD levels (10–30 ng/mL) and the second group consisted of 121 patients with 25-(OH) VD deficiency (≤10 ng/mL). The relationship between 25-(OH) VD levels and the level of microalbuminuria was evaluated in the two groups. Results: The mean 25-(OH) VD level was 11.5 ng/mL and the mean HbA1c level was 9.1%. When the patient groups were evaluated according to 25-(OH) VD levels, HbA1c values were significantly higher in patients with a 25-(OH) VD level of 10 ng/mL or lower (p =.039). 25-(OH) VD levels were not significantly different between patients with different stages of renal failure (p =.119), whereas the level of microalbuminuria was significantly different (p =.030). Conclusions: This study found that the level of microalbuminuria was significantly higher in patients with 25-(OH) vitamin D deficiency compared to patients with 25-(OH) VD insufficiency.
