Применение витаминов может снизить риск и тяжесть течения вирусных инфекций, что и показали проведенные ранее исследования. Полученные данные обусловили интерес к изучению эффективности этих витаминов у людей с новой коронавирусной (SARS-CoV-2) инфекцией. Цель статьи — оценить содержание витаминов А, С, состояние перекисного окисления в сыворотке крови больных с постковидным синдромом. Случайным образом были отобраны 30 больных в возрасте от 43 до 63 лет. Для дальнейшего анализа были сформированы 2 группы: 1-я группа — 12 человек, переболевших новой короновирусной инфекцией. 2-я группа — 18 больных, не болевших COVID-19, но предъявляющих жалобы на бессонницу, тревожность, снижение работоспособности, вялость. Оценивались результаты анализов крови. Измеряли сывороточные уровни витаминов А, С и малонового диальдегида. В образцах мочи определяли содержание витамина С. Выявлено, что у пациентов с постковидным синдромом наблюдаются существенные изменения показателей уровней витамина А и С, которые запускают процессы, приводящие к окислительному стрессу.</p></abstract><trans-abstract xml:lang="en"><p>Vitamins C and A have an immunostimulating effect, and their deficiency leads to an increased risk of developing viral infections. Numerous studies have indicated that the administration of vitamins can decrease the risk and severity of viral infections. The data obtained have stimulated an interest in the efficacy of these vitamins in people with a new coronavirus (SARS-CoV-2) infection. The article aims to evaluate the content of vitamins A, C, as well as peroxidation activity in the blood serum of patients with post-COVID syndrome. For the analysis, 30 patients aged 43 to 63 years were randomly selected, and 2 groups were formed. Group 1 included 12 patients with post-COVID syndrome, who have had a severe disease requiring hospitalization. Group 2 included 18 patients who did not have the new coronovirus infection but complained of physical and mental fatigue, muscle weakness. The serum levels of vitamin A, C and malondialdehyde were measured. Vitamin C content was determined in urine samples. It has been found that patients with postCOVID syndrome demonstrate significant changes in vitamin A and C levels, which trigger the processes that result in oxidative stress.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>витамин А</kwd><kwd>витамин С</kwd><kwd>постковидный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>SARS-CoV-2</kwd><kwd>COVID-19</kwd><kwd>vitamin C</kwd><kwd>vitamin A</kwd><kwd>post-covid syndrome</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Manion M., Hullsiek K.H., Wilson E.M.P. et al.
