Abstract
BACKGROUND. Vitamin D has been known since 1928. The wide range of its metabolic effects paradoxically contrasts with the high prevalence of insufficiency and deficiency in the population of different regions of the world. A number of publications have demonstrated information about the relationship between vitamin D and insulin production by beta cells of the pancreas, as well as the excretory function of the kidneys.THE AIM: to assess the level of vitamin D in patients with diabetes mellitus in combination with chronic kidney disease (CKD).PATIENTS AND METHODS. A questionnaire and a study of the level of 25-hydroxyvitamin D, creatinine, urea, and glucose in the blood were conducted in 117 patients aged 18 to 84 years who gave voluntary consent. All patients were divided into three study groups: group 1 - patients with long-term DM, group 2 - patients with newly diagnosed DM, and 3 - control group. The glomerular filtration rate (GFR) is calculated by the formula CKD-EPI.RESULTS. As a result of the study, it was found that patients with DM, regardless of the duration of its course, were more likely to suffer from vitamin D deficiency, compared with the control group, where D-deficiency and D-deficiency occurred with the same frequency. In addition, patients with DM were more likely to have stage 2-3A CKD, in contrast to the control group, where preserved kidney function prevailed. We also identified and confirmed the direct dependence of GFR on the level of vitamin D in the blood of patients with DM.CONCLUSION. In the patients studied by us, a clear association was found between a lower vitamin D index in the blood serum and the presence of a history of diabetes. They also showed a tendency to decrease the excretory function of the kidneys and the formation of CKD. Consequently, a full-fledged diagnosis of vitamin D-deficient conditions and timely initiated therapy can prevent or at least slow down the progression of CKD in these patients, which will certainly improve their quality of life and reduce the costs of health services for renal replacement therapy and rehabilitation of this group of patients.
