Выявить взаимосвязь между сывороточным содержанием витамина D и полиморфизмом генa рецептора витамина D c тяжестью течения COVID-19-ассоциированного поражения легких. Материалы и методы. В работе представлены результаты обследования 200 человек через 1 месяц после перенесенного COVID-ассоциированного поражения легких в период с 01 июня по 31 октября 2020 года. Пациенты разделены на группы по 50 человек в зависимости от степени поражения легких по результатам проведения компьютерной томографии: 1-я группа (КТ-1), медиана по возрасту составила 51,5 [50,5; 54,8]; 2-я группа (КТ-2), медиана по возрасту 57,0 [53,1; 57,0]; 3-я группа (КТ-3), медиана по возрасту 52,5 [51,9; 55,0]; 4-я группа (КТ-4), медиана 55,0 [53,2; 56,4]. В группу контроля вошли 56 человек относительно здоровых лиц, не болевших коронавирусной инфекцией, медиана по возрасту составила 55,0 [51,1; 55,0]. Все группы были сопоставимы по возрасту и полу. В сыворотке крови исследовали концентрацию общего 25-гидроксивитамина D (25(ОН)D). Также проведено молекулярногенетическое исследование генa рецептора витамина D: 283 A&gt;G (BsmI) и 2 A&gt;G (FokI). Результаты. Учитывая полученные результаты у пациентов, перенесших COVID-19-ассоциированное поражение легких, можно предположить, что недостаточное содержание в крови общего 25-гидроксивитамина D может являться одним из факторов, способствующих осложненному течению коронавирусной инфекции, а также фактором риска ухудшения течения COVID-19-ассоциированного поражения легких. Анализ полиморфизма генa рецептора витамина D VDR: 283 А&gt;G показал преимущественное наследование аллели А и гомозиготы А/А у пациентов с большим уровнем повреждения легочной ткани на фоне COVID-19 инфекции — КТ-3, 4. Изучение полиморфизма гена рецептора витамина D VDR: 2 А&gt;G показало преимущественное наследование гомозиготы A/A среди заболевших по сравнению с группой контроля. При изучении концентрации витамина D у пациентов с COVID-19-ассоциированным поражением легких в зависимости от полиморфизма генов рецептора витамин D VDR: 283 А&gt;G (BsmI) и VDR: 2 А&gt;G (FokI) отличий не выявлено. Заключение. Недостаточное содержание в крови 25(ОН)D может являться одним из факторов, способствующих осложненному течению коронавирусной инфекции. Анализ полиморфизма гена рецептора витамина D VDR: 283 А&gt;G показал преимущественное наследование аллели А и гомозиготы А/А у более тяжелой категории пациентов — с объемом повреждения легочной ткани более 50 % (КТ-3, 4) на фоне COVID-19 инфекции. Изучение полиморфизма гена рецептора витамина D VDR: 2 А&gt;G выявило среди заболевших наиболее распространенное носительство гомозиготы A/A по сравнению с группой контроля.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To identify the relationship between the serum vitamin B content and the polymorphism of the vitamin B receptor gene with the severity of the course of COVID-19-associated lung damage.</p><p>To identify the relationship between serum vitamin D content and polymorphism of the vitamin D receptor gene with the severity of COVID-19- associated lung damage. Materials and methods. The paper presents the results of an examination of 200 people, after 1 month suffering COVID-associated lung damage in the period from June 1 to October 31, 2020. The patients were divided into groups of 50 people depending on the degree of lung damage based on the results of computed tomography: group 1 (CT-1), median by age was 51.5 [50.5; 54.8]; group 2 (CT-2), median by age 57.0 [53.1; 57.0]; group 3 (CT-3), median by age 52.5 [51.9; 55.0]; group 4 (CT-4), median 55.0 [53.2; 56.4]. The control group included 56 relatively healthy people who did not have coronavirus infection; the median age was 55.0 [51.1; 55.0]. All groups were comparable in age and gender. The concentration of total 25-hydroxyvitamin D (25(OH)D) was studied in blood serum. A molecular genetic study of the vitamin D receptor gene was also carried out: 283 A&gt;G (BsmI) and 2 A&gt;G (FokI). Results. It was revealed that insufficient levels of 25(OH)D in the blood are one of the risk factors for the development of COVID-19 infection, as well as a risk factor for worsening the course of COVID-19-associated lung damage. Analysis of the polymorphism of the vitamin D receptor gene VDR: 283 A&gt;G showed the predominant inheritance of allele A and homozygote A/A in patients with a high level of damage to lung tissue due to COVID-19 infection — KT-3, 4. Study of polymorphism of the vitamin D receptor gene VDR: 2 A&gt;G showed preferential inheritance of homozygote A/A among patients compared to the control group. When studying the concentration of vitamin D in patients with COVID-19-associated lung damage depending on the polymorphism of the vitamin D receptor genes VDR: 283 A&gt;G (BsmI) and VDR: 2 A&gt;G (FokI), no differences were found. Conclusion. Insufficient levels of 25(OH)D in the blood may be one of the factors contributing to the complicated course of coronavirus infection. Analysis of the vitamin D receptor gene polymorphism VDR: 283 A&gt;G showed preferential inheritance of the A allele and homozygote A/A in a more severe category of patients — with more than 50 % damage to the lung tissue (CT-3, 4) against the background of COVID-19 infection. A study of the polymorphism of the vitamin D receptor gene VDR: 2 A&gt;G revealed the most common carriage of the A/A homozygote among patients compared to the control group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19-ассоциированное поражение легких</kwd><kwd>полиморфизм генa рецептора витамина D: 283 A&gt;G (BsmI) и 2 A&gt;G (FokI)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19-associated lung damage</kwd><kwd>vitamin D receptor gene polymorphism: 283 A&gt;G (BsmI) and 2 A&gt;G (FokI)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке ФГБОУ ВО Читинская государственная медицинская академия Минздрава РФ в рамках утвержденного плана НИР.</funding-statement><funding-statement xml:lang="en">The work was carried out with the financial support of the Chita State Medical Academy of the Ministry of Health of the Russian Federation within the framework of the approved research plan.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Colotta F., Jansson B., Bonelli F.
