Vitamin D is a fat-soluble secosteroid that plays an important role in the human body. There are two main native forms – vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). The regulation of calcium-phosphate metabolism and ensuring adequate bone remodeling are the most studied function of vitamin D. In recent years, researchers have found out the «extra-bone» effects of vitamin D and it allows us to be convinced of the great role of this compound. The participation of active forms of vitamin D in the processes of immunomodulation, anti-inflammatory, antimicrobial, antiproliferative effects and stimulation of cell differentiation are reflected in diseases of the maxillofacial region.In this article, we examined the main functions of vitamin D in the human body, the mechanisms of its action and influence on the occurrence and course of oral diseases. The discovery of the relationship between vitamin D deficiency and the processes of osseointegration, bone remodeling, the severity of chronic recurrent aphthous stomatitis, squamous cell carcinoma and periodontitis allow us to conclude that it is advisable to diagnose vitamin D deficiency in appropriate time and correction its serum level in dental patients.

Background: Vitamin D deficiency is a worldwide health issue and its role as an immune modulator has recently been emphasized. Evidence increasingly indicates the important role of vitamin D in reducing the incidence of autoimmune diseases. However, at this time the search for its role in autoimmune diseases and thyroid is not critical. Objectives: The study aimed to assess the relationship between vitamin D deficiency in Sudanese patients with hypothyroidism. Methods: Analytical case control hospital based study, conducted in Fadil Hospital and Police Hospital, Khartoum city, Khartoum state. The study carried out from March 2018 to September 2018. A total of 100 subjects were enrolled in the study. Vitamin D deficiency was set at levels below 20 ng / ml. Thyroid hormones (TSH, T3 and T4) were assessed in all participants using auto analyzer TOSOH AIA 313,while vitamin D was estimated using ELIZA. The data were analyzed using SPSS version (21). Results: The study included 76(76%) females and 24(24%) males, no significance differences between thyroid profile among study population.75 (75%) deficiency of vitamin D and 25(25%) normal vitamin D. vitamin D deficiency was significantly lower in female than male with( p =0.001). Conclusion: The results indicated that patients with hypothyroidism suffer from vitamin D deficiency significantly associated with the degree and severity of hypothyroidism. This encourages the desirability of vitamin D supplementation and recommends the detection of vitamin D deficiency for all hypothyroidism patients.

The article presents an analysis of literary sources about contemporary views on the role of vitamin D deficiency in the health problems of women of the perimenopausal period. According to research data of recent years, vitamin D plays a role not only in the control of calcium-phosphorus metabolism, but also plays a role in the pathogenesis of cardiovascular and neurological diseases, insulin resistance and diabetes, in the development of cancer and autoimmune conditions, especially in women of perimenopausal age. It is important to continue the study of the relationship between vitamin D deficiency and menopausal and menopausal disorders. Currently, the existing principles and effectiveness of the correction of lack of vitamin D in improving the quality of life of women of perimenopausal age are ambiguously assessed, which determines the relevance of this research direction. Key words: perimenopausal period, insufficiency/deficiency of vitamin D.

Sarcopenia is a prevalent condition in patients with Crohn’s disease (CD), representing an independent predictor factor for the development of major postoperative complications. Thus, a proper assessment of the muscle strength, by using different validated tools, should be deemed an important step of the clinical management of these patients. Patients with CD are frequently malnourished, presenting a high prevalence of different macro- and micro-nutrient deficiencies, including that of vitamin D. The available published studies indicate that vitamin D is involved in the regulation of proliferation, differentiation, and regeneration of muscle cells. The relationship between vitamin D deficiency and sarcopenia has been extensively studied in other populations, with interesting evidence in regards to a potential role of vitamin D supplementation as a means to prevent and treat sarcopenia. The aim of this review was to find studies that linked together these pathological conditions.

Abstract Vitamin D, also known as the “sun vitamin” in the literature, has been examined for many years and still arouses researchers’ interest due to the pleiotropic effects achieved in the human body. Because of the influence on mineral homeostasis, the initially observed effects of vitamin D on the prevention and treatment of rickets, have now been extended to a large number of diseases with different aetiologies such as cardiovascular, autoimmune, endocrine, infectious, neurological, malignant and other diseases. Due to the large number of experimental studies in animals and humans, we have exact information about the role of vitamin D in many of these conditions. Reaching an adequate level of 25(OH)D in the human body is a basic requirement for the realization of these effects; 25(OH)D is a metabolic product that reflects the vitamin D status but that does not have any biological activity. The biological activities of vitamin D can occur only after the formation of a second metabolic product, 1,25(OH)2D, in the kidneys. The three main sources of acquiring vitamin D are through food, skin and supplementation. Food is not a rich source of vitamin D; it is clear that the most important influences to achieve an optimal vitamin D status in the human body are vitamin D synthesis at the skin and adequate supplementation intake. An alarming fact is that vitamin D deficiency is detected in an increasing number of people from one day to another in the general world population and that this condition has pandemic dimensions. Introducing the beneficial effects and sources of vitamin D to the general population and to medical experts with adequate supplementation regime can decrease the number of people who are vitamin D deficient.

BACKGROUND. The main task of modern phthysiology is a comprehensive search for ways to optimize the etiotropic and the pathogenetic treatment of tuberculosis (TB). The search for improved treatment in addition to etiotropic antimicrobial therapy lies in the plane of improving pathogenetic therapy. Analysis of the available scientific sources suggests that the efficacy of TB treatment can be improved by adding vitamin D to the pathogenetic treatment, as vitamin D metabolites support the innate immune response to Mycobacterium tuberculosis. OBJECTIVE. To determine the role of vitamin D in the immunopathogenesis of the inflammatory response in pulmonary TB and to assess the prospects of its impact on improving the effectiveness of treatment by analyzing information from available scientific sources on this topic. MATERIALS AND METHODS. The study was performed for the period December 2020 – August 2021. The search was conducted by Keywords: pulmonary tuberculosis, vitamin D, mechanism of action, pathogenesis, treatment. Access to various full-text and abstract databases was used as the main source of research. RESULTS AND DISCUSSION. A large number of studies conducted so far prove the link between vitamin D deficiency and the occurrence of pulmonary TB. Vitamin D receptors have been found to be present on various surfaces of immune cells, including T and B cells, indicating that they need vitamin D to perform cellular functions. Vitamin D has been shown to increase the phagocytic activity of macrophages, and that monocytes incubated with cholecalciferol (vitamin D3) metabolites induce anti-TB activity. A number of studies have shown that vitamin D increases the body’s production of the antimicrobial/antimycobacterial peptide LL-37, a member of the cathelicidin petelide family. Therefore, the narrowly analyzed analysis according to the literature suggests that in the conditions of full vitamin D status of the human body the course of TB will be favorable, and in case of vitamin D deficiency – which is primarily associated with genetic polymorphisms, the course of TB may be unfavorable. CONCLUSIONS. Vitamin D functionates as one of the activators of macrophages and plays a role in the immune defense of the human body against mycobacterial TB. The inclusion of vitamin D in the program of complex treatment of TB infection is promising, as it enhances the production of antimicrobial/antimycobacterial peptide LL-37. It can be used as one of the components of TB prevention in children.

AbstractDuring pregnancy, maternal vitamin D insufficiency could increase the risk of preeclampsia. Aim of the study was to evaluate the relationship between vitamin D status and the occurrence of placenta-mediated complications (PMCs) in a population at high risk. A prospective multicenter cohort study of 200 pregnant patients was conducted. The vitamin D level of patients with placenta-mediated complications was lower at 32 weeks compared to uncomplicated pregnancies (P = 0.001). At 32 weeks, the risk of occurrence of PMCs was five times higher in patients with vitamin D deficiency (RR: 5.14 95% CI (1.50–17.55)) compared to patients with normal vitamin D levels. There was a strong, inverse relationship between serum 25(OH)D levels at 32 weeks and the subsequent risk of PMCs (P = 0.001). At 32 weeks, the vitamin D level of patients with late-onset PMCs was lower than the one of patients with early-onset PMCs and of patients without PMCs (P < 0.0001). These results suggest a role of vitamin D in the maintenance of placental performance and therefore in the prevention of the onset of late PMC.
