В исследование включали пациентов в возрасте от 18 лет с подтвержденным диагнозом COVID-19 (по результатам полимеразной цепной реакции (ПЦР) или серологического исследования), у которых спустя не менее 12 месяцев после выздоровления выявляли АН. Исключались случаи вторичного некроза (хронический алкоголизм, длительная кортикостероидная терапия по другим показаниям, травмы), а также пациенты с ревматологическими или онкологическими заболеваниями костей.</p> <p>Результаты показали повышенный риск развития АН у лиц, перенесших тяжелую форму COVID-19 и/или получавших высокие дозы глюкокортикостероидов. При этом у части пациентов наблюдались аутоиммунные нарушения (повышенный уровень антинуклеарного фактора, антифосфолипидных антител), способствующие формированию некротических изменений в костях.</p> <p>Полученные данные подчеркивают необходимость комплексной оценки суставных осложнений у пациентов с тяжелым течением COVID-19, а также важность мониторинга (МРТ, рентген) для ранней диагностики АН.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>aseptic necrosis (osteonecrosis)</kwd><kwd>glucocorticoids</kwd><kwd>post-COVID-19 complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>асептический некроз (остеонекроз)</kwd><kwd>глюкокортикостероиды</kwd><kwd>постковидные осложнения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Goncharov E.N., Koval O.A., Nikolaevich Bezuglov E., Aleksandrovich Vetoshkin A., Gavriilovich Goncharov N., Encarnación Ramirez M.J., Montemurro N.
