The role of vitamin D in the prevention of pathology associated with psoriasis and metabolic syndrome

Abstract

The paper highlights modern views on the metabolism of vitamin D in the human body. The analysis of the literature data on the mechanisms of the effect of vitamin D deficiency on the pathological processes occurring in the skin with psoriasis is carried out. It is known that psoriasis is associated with a high prevalence of metabolic syndrome, diabetes mellitus, and cardiovascular diseases. There is a direct correlation between a decrease in vitamin D levels and an increased risk of developing metabolic syndrome and cardiovascular mortality, including in patients with psoriasis. Data on the possibility of using vitamin D in dermatology are presented. Based on international and Russian clinical recommendations, the place of oral colecalciferol preparations in the prevention and correction of vitamin D deficiency and deficiency has been determined. The use of oral vitamin D for the simultaneous treatment of psoriasis and metabolic syndrome reduces the risk of cardiovascular diseases and type 2 diabetes mellitus. We analysed the international and domestic recommendations for the treatment of vitamin D deficiency and insufficiency, the use of which makes the oral administration of vitamin D3 (cholecalciferol) optimal for the treatment and prevention of vitamin D deficiency, as the results of several studies showed a higher efficacy of vitamin D3 vs vitamin D2. Vitamin D3 is found in vitamin D-fortified foods and is available as dietary supplements and drugs. The bioavailability of vitamin D in dietary supplements may differ depending on the used vehicle substance.
