The objective of the research is to analyze the association of Bsml polymorphism of the vitamin D receptor gene in patients with comorbidity - chronic pancreatitis (CP) and chronic obstructive pulmonary disease (COPD), as well as to correct the serum vitamin D level.Material and methods. The study included 57 patients with CP with concomitant COPD, who were hospitalized in the gastroenterology department of the Chernivtsi Regional Clinical Hospital. COPD was in a state of stable or unstable remission. The average age of the examined patients was 52.36 ± 1.83 years. The inclusion criterion was vitamin D deficiency diagnosed in patients with chronic pancreatitis and chronic obstructive pulmonary disease. The exclusion criterion was another nosology that could cause disorders of vitamin D metabolism. Results. 57 patients had vitamin D deficiency. No patients with normal vitamin levels were recorded. Thus, the average level of vitamin D in respondents with vitamin D deficiency was 36.13 ± 7.61. After genotyping and distribution according to a specific genotype, a vitamin deficiency correction scheme was selected. Cholecalciferol at a dose of 6000 IU for 2 months was prescribed for the G/G genotype patients. Patients with G/A and A/A genotypes received the same drug at a dose of 8000 IU for 2 months, followed by determination of serum vitamin D levels.Conclusions. For patients with A allele (genotypes AA and AG), the genetic risk of developing vitamin D deficiency is higher than the average population level. For patients with moderate and severe exocrine pancreatic insufficiency and signs of malabsorption syndrome, it is recommended to check not only the level of 25 (OH) D in the serum, but also to determine the polymorphic variant of the VDR gene to approve further treatment tactics - determine the optimal dose and check its effectiveness.
