Sumario:Type 2 diabetes mellitus (DM) is a global epidemic associated with severe vascular complications development. Diabetic neuropathy is the most common chronic complication of DM that worsens patients’ life quality and prognosis. Therefore, studies dealing with DM and diabetic neuropathy underlying mechanisms are extremely relevant. The review discusses current views on vitamin D role in glucose metabolism and inflammatory processes. It is reported that vitamin D deficiency can contribute to insulin resistance development, and change in vitamin D receptor activity or extra- and intracellular calcium concentration due to vitamin D deficiency can affect pancreatic β-cells function and lead to decrease in insulin production. Key pathogenic mechanisms of diabetic neuropathy as well as possible relationship between vitamin D deficiency and neuropathy development are in focus of this review. Results of recent clinical trials regarding vitamin D supplementation in patients with DM are also discussed. The presented data suggest that vitamin D deficiency can be considered as a non-classical risk factor for the development of not only DM but its complications as well.
