Resumen

The existence of impaired glucose tolerance in vitamin D-deficient individuals and the discovery of receptors for 1,25- dihydroxyvitamin D3 –the activated form of vitamin D– in islet b-cells and immune cells, the main cells involved in the pathogenesis of both types of diabetes, have aroused scientific and clinical interest in the potential role of vitamin D in the pathogenesis of the diseases, but even more so with respect to its therapeutic potential in the prevention of both forms of diabetes. Vitamin D deficiency is detrimental to insulin synthesis and secretion in animal models, as well as in humans, and predisposes them to type 2 diabetes. Interventions with pharmacological doses of 1,25- dihydroxyvitamin D3 or newer structural analogues can delay onset of type 1 diabetes in non-obese diabetic mice, mainly through immunomodulation, but, to date, no human data are available. Epidemiological studies suggest links between onset of type 1 diabetes and vitamin D deficiency in early life and with certain polymorphisms of the vitamin D receptor. At present, the most important conclusion from the studies on vitamin D and diabetes is that avoiding vitamin D deficiency is a priority not only for calcium and bone issues, but also for diabetes prevention.
