The relationship of vitamin D with compensation of carbohydrate metabolism in patients with type 2 diabetes mellitus combined with non-alcoholic fatty liver disease
Background. Changes of vitamin D level and its influence on the indexes of carbohydrate metabolism compensation in patients with type 2 diabetes mellitus (DM) combined with non-alcoholic fatty liver disease (NAFLD) are studied not enough. Aim: to study vitamin D content in patients with type 2 DM and correlation of carbohydrate metabolism compensation, the state of lipid metabolism, levels of transaminases with vitamin D level. Materials and methods. Sixty patients with type 2 DM associated with NAFLD aged 48 to 80 (on the average 63.30 ± 0.89) years were examined. Among the surveyed persons, there were 40 women (67 %) and 20 men 20 (33 %). All patients were divided into two groups: group 1 (32 persons) consisted of patients with DM type 2 combined with NAFLD and osteoporosis; group 2 (28 people) — individuals with type 2 DM associated with NAFLD without osteoporosis. Results. The paper presents the results of the examined groups of patients (type 2 DM in combination with NAFLD with and without osteoporosis); vitamin D deficiency or insufficiency was detected, that is, none of the patients didn’t have an adequate supply of vitamin D. Patients from the above groups had dyslipidemia on a background of a low 25(OH)D content. The levels of total cholesterol, β-lipoproteins, triglycerides, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol, as well as atherogenic index were statistically significantly increased with decreasing levels of vitamin D; therefore, there was an inverse correlation between the above indicators. Statistically significant differences were not found between the levels of total bilirubin, an indicator of thymol samples and the level of vitamin D. Conclusions. An increase was noted in transaminase concentration compared to their normative values, as well as a decrease in the De Ritis ratio with a simultaneous decrease in vitamin D content.
