The “nonclassic” role of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) has been recently widely recognized. In type 1 diabetes mellitus (T1D), it plays an immunomodulatory role through the vitamin D receptor (VDR) present on pancreatic and immune cells. Specific VDR allelic variants have been associated with T1D in many countries. Furthermore, vitamin D deficiency has been prevalent in T1D, and the seasonal and latitude variability in the incidence of T1D can be partly explained by the related variability in vitamin D level. In fact, retrospective studies of vitamin D supplementation during pregnancy or infancy showed a lower incidence of T1D. We will review the different mechanisms of the vitamin D protective effect against insulitis and present the available data on the role of vitamin D deficiency in the control, progression, and complications of T1D.

The incidence of type 1 diabetes mellitus is increasing worldwide, and the number of people with vitamin D deficiency in all age groups, including children and adolescents, is simultaneously growing in the world. Over the past decades, it has been found that vitamin D, in addition to participating in the regulation of calcium homeostasis and bone metabolism, has an anti-inflammatory and immunomodulatory effect. Epidemiological evidence suggests the involvement of vitamin D deficiency in the pathogenesis of type 1 diabetes mellitus. Polymorphisms in genes important for vitamin D metabolism also modulate the risk of type 1 diabetes mellitus. Several studies have evaluated the role of vitamin D as adjuvant immunomodulating therapy in patients with newly diagnosed type 1 diabetes mellitus. The purpose of this review is to present current data on the involvement of vitamin D in the pathogenesis of type 1 diabetes mellitus and to evaluate its role as a drug for the prevention of the disease and its use in treatment in addition to insulin therapy.
