Инфицирование человека ассоциированным с тяжелым острым респираторным синдромом коронавирусом 2 (SARS-CoV-2) формирует полиморфную картину инфекционного заболевания (COVID-19) в диапазоне от легких форм острой респираторной инфекции до тяжелых и угрожающих жизни вариантов течения системной инфекции с вовлечением дыхательных путей. Среди значимых предикторов тяжелого течения и летального исхода у больных с поражением легких, ассоциированным с инфекционным заболеванием COVID-19, выделяют увеличение плазменного содержания D-димеров, гомоцистеина, некоторые однонуклеотидные полиморфизмы (single nucleotide polymorphisms — SNP) генов белков — участников фолатного цикла.Цель. Оценить роль генетических маркеров нарушений метаболизма фолиевой кислоты в развитии симптомов и исходов ассоциированного с коронавирусом SARS-CoV-2 поражения легких у госпитализированных пациентов.Материалы и методы. В открытом проспективном сравнительном исследовании 117 больных с поражением легких, ассоциированным с инфицированием коронавирусом SARS-CoV-2, проведен анализ исходов в зависимости от полиморфных маркеров генов белков фолатного цикла и применения в комплексной терапии фиксированной комбинации фолиевой кислоты с витаминами В6, В12.Результаты. У пациентов наблюдался повышенный относительный риск гетерозиготного носительства минорного аллеля G однонуклеотидного полиморфизма гена метионинсинтазыредуктазы (MTRR) 66AG. Гомозиготный генотип MTRR 66GG ассоциировался с показателями анемии и тромбоцитопении. Установлено статистически значимое снижение отношения шансов (ОШ) достижения к 14-му дню терапии отрицательного результата определения РНК SARS-CoV-2 у пациентов с гетерозиготным генотипом 677CT и гомозиготным генотипом 677ТT гена метилентетрагидрофолатредуктазы (MTHFR).Заключение. Поражение легких, вызванное коронавирусом SARS-CoV-2, ассоциируется с повышенным риском генетически обусловленного нарушения метаболизма фолата и витамина В12.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Infection with human coronavirus 2 (SARS-CoV-2) associated with severe acute respiratory syndrome, forms polymorphous pattern of the infectious disease (COVID-19) in the range from mild acute respiratory infection to severe and life-threatening variations of systemic infection with respiratory tract involvement. Among significant predictors of the severe course and lethal outcome in the individuals with lung affection associated with COVID-19 infection, the increase of plasma levels of D-dimer, homocysteine, and some single-nucleotide polymorphisms (SNPs) of genes of the folate cycle proteins are singled out.Aim. To assess the role of genetic markers of folic acid metabolic disorders in the development of symptoms and the outcomes of viral lung damage associated with SARS-CoV-2 infection in the hospitalized patients.Materials and methods. In an open prospective comparative study the assessment of outcomes depending on polymorphic markers of protein genes of the folate cycle and the use of fixed combination of folic acid and vitamins В6, В12 in comprehensive therapy was performed in 117 patients with lung damage associated with SARS-CoV-2 infection.Results. Patients showed an increased relative risk of the heterozygous minor G-allele carriage of 66AG SNP of the methionine synthase reductase gene (MTRR). The homozygous MTRR G66G genotype was associated with indicators of anemia and thrombocytopenia. A statistically significant decrease in the odds ratio in achieving negative results for SARSCoV-2 RNA detection by the 14th day of therapy in patients with the heterozygous 677CT genotype and the homozygous 677TT genotype of the MTHFR (methylenetetrahydrofalate reductase) gene was established.Conclusion. Lung damage caused by SARS-CoV-2 infection is associated with an increased risk of genetic metabolic disorder of folate and vitamin B12.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>однонуклеотидные полиморфизмы генов</kwd><kwd>MTRR 66AG</kwd><kwd>MTHFR 677CT</kwd><kwd>MTHFR 677ТT</kwd><kwd>фолиевая кислота</kwd><kwd>коронавирус SARS-CoV-2</kwd><kwd>вирусное поражение легких</kwd></kwd-group><kwd-group xml:lang="en"><kwd>single-nucleotide polymorphisms of genes</kwd><kwd>MTRR 66AG</kwd><kwd>MTHFR 677CT</kwd><kwd>MTHFR 677TT</kwd><kwd>folic acid</kwd><kwd>SARSCoV-2</kwd><kwd>viral lung damage</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">Woolf S.H., Chapman D.A., Lee J.H.
