В условиях пандемии COVID-19 данные интервенционных исследований показывают положительное влияние добавления препаратов витамина D на клинико-лабораторные показатели и исход заболевания. Ранее не проводились интервенционные исследования, анализирующие параметры метаболизма витамина D в остром периоде COVID-19.</p></sec><sec><title>Цель</title><p>Цель. Оценить уровень 25(OH)D и 1,25(OH)2D у госпитализированных больных с COVID-19, а также их динамику на фоне болюсного применения колекальциферола.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В группе 1 (n = 22) к основной терапии COVID-19 был добавлен болюсный прием колекальциферола в суммарной дозе 100 000 МЕ; больные группы 2 (n = 22) колекальциферол не получали. В каждой группе были определены уровни 25(ОН)D и 1,25(ОH)2D на 1-й и 9-й дни госпитализации.</p></sec><sec><title>Результаты</title><p>Результаты. В группе 1 выявлено повышение уровня 25(OH)D сыворотки крови на 45,8 % на 9-й день госпитализации, в то время как в группе 2 уровень 25(OH)D снизился на 17,9 %. При оценке уровня 1,25(ОH)2D не было получено различий в его уровне в обеих группах к 9-му дню госпитализации, а при попарном сравнении показателей на 1-й и на 9-й дни госпитализации отмечалось повышение концентрации 1,25(ОH)2D (p &lt; 0,001) в обеих группах. </p></sec><sec><title>Заключение</title><p>Заключение. Такие параметры метаболизма витамина D в остром периоде COVID-19, возможно, ассоциированы с изменением активности 1α-гидроксилазы как на фоне активного инфекционного процесса, так и при использовании терапии ГКС, что обуславливает увеличение концентрации активной формы витамина D вне зависимости от уровня 25(ОН)D.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Recently, clinical benefits among COVID-19 patients, received vitamin D were demonstrated. Features of vitamin D metabolism in the acute period of COVID-19 remain unclear.</p></sec><sec><title>Objective</title><p>Objective. To assess the level of 25(OH)D and 1,25(OH)2D in hospitalized COVID-19 patients and cholecalciferol effect on the vitamin D metabolites dynamic.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Group 1 (n = 22) patients received cholecalciferol bolus therapy at a total dose of 100,000 IU. Group 2 patients (n = 22) did not receive cholecalciferol supplementation. Serum 25(OH)D and 1,25(OH)2D levels were estimated for each group on the first and the ninth day of hospitalization.</p></sec><sec><title>Results</title><p>Results. On the ninth day of hospitalization 25(OH)D serum level demonstrated the 45.8 % rise in the Group 1, while in the Group 2 there was a decrease in the 25(OH)D level by 17.9%. At the same time, dynamic evaluation of the 1.25(OH)2D level did not show any differences between the groups, while pairwise comparison on the first and on the ninth days of hospitalization revealed an increase in the active metabolite concentration (p &lt; 0.001) in both groups.</p></sec><sec><title>Conclusion</title><p>Conclusion. Such vitamin D metabolism parameters in the acute period of COVID-19 may be associated with a 1α-hydroxylase activity alteration. Thus, 1.25(OH)2D serum level increase regardless of vitamin D status during the hospitalization could be explained by the COVID-19 course or concomitant corticosteroid medication.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>метаболизм витамина D</kwd><kwd>терапия колекальциферолом</kwd><kwd>СOVID-19</kwd><kwd>1</kwd><kwd>25(ОH)2D</kwd><kwd>25(ОH)D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>1</kwd><kwd>25(ОH)2D</kwd><kwd>25(ОH)D</kwd><kwd>cholecalciferol supplementation</kwd><kwd>СOVID-19</kwd><kwd>vitamin D metabolism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования Российской Федерации (Соглашение № 075-152022-301 от 20.04.2022).</funding-statement><funding-statement xml:lang="en">The study was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15-2022-301 dated 04/20/2022).</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">Kaufman H, Niles J, Kroll M, et al.
