Прошедшая пандемия COVID-19 оказала влияние на течение многих заболеваний, включая эндокринные. Однако о клинико-патогенетических особенностях тиреоидной патологии, возникшей в постковидном периоде, известно мало.</p></sec><sec><title>Цель</title><p>Цель. Оценить клинические и патогенетические особенности тиреопатий постковидного периода.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено поперечное исследование с включением 250 больных, которым впервые поставили диагноз заболевания щитовидной железы. 73 участника отрицали анамнез COVID-19, а 177 перенесли его в течение предшествующих 9 мес. У всех оценивали тиреоидный статус и показатели ультразвукового исследования щитовидной железы. У 40 больных с анамнезом COVID-19 определяли уровни IgG к вирусу SARS-Cov-2. У 61 пациента проведена тонкоигольная аспирационная биопсия, в т. ч. у 41 с анамнезом COVID-19. В основной группе все образцы были дополнительно подвергнуты иммуноцитохимическому анализу с использованием антител к белку SARS-CoV-2.</p></sec><sec><title>Результаты</title><p>Результаты. В группе больных с COVID-19 в анамнезе отмечались больший уровень свТ4 (13,6 [12,4; 15,5] vs 12,8 [11,0; 15,3] мкмоль/л, р = 0,046) и меньшая доля лиц с эутиреозом (122 (68,9%) vs 59 (80,8%), р = 0,037). В основной группе было больше цитологических образцов со скоплениями макрофагов (16 (39,0%) vs 2 (10,0%), р = 0,017), однако иммуноцитохимическое исследование не выявило ни одного SARS-Cov-2-позитивного образца. В динамике постковидного периода примерно у 60% больных с субклиническими тиреоидными дисфункциями происходила их спонтанная нормализация. Имелись корреляционные взаимосвязи между уровнем IgG к SARS-Cov-2 и показателями структурно-функционального состояния щитовидной железы.</p></sec><sec><title>Выводы</title><p>Выводы. Основной клинической особенностью тиреоидной патологии, впервые выявленной после COVID-19, является меньшая доля лиц с эутиреозом. В динамике выявленные в постковидном периоде легкие дисфункции щитовидной железы имели тенденцию к спонтанной нормализации в 60% случаев. Результаты иммуноцитохимического исследования говорят об отсутствии персистенции SARS-Cov-2 в щитовидной железе. В патогенезе постковидных тиреопатий участвуют COVID-19- ассоциированные иммунопатологические реакции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The past COVID-19 pandemic has influenced the course of many diseases including endocrine pathology. However, little is known about the clinical and pathogenetic features of thyroid pathology of the post-COVID-19 period.</p></sec><sec><title>Aim</title><p>Aim. Evaluate the clinical and pathogenetic features of thyropathies diagnosed during the post-COVID-19 period.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A cross-sectional study included 250 patients with newly diagnosed thyroid diseases. 73 participants denied a history of COVID-19 and 177 suffered from it within the previous 9 months. Thyroid status and thyroid ultrasound examination were assessed. IgG SARS-Cov-2 levels were tested in 40 patients with a history of COVID-19. Fine needle aspiration biopsy was performed in 61 patients including 41 with a history of COVID-19. In the main group, all the samples were additionally investigated by immunocytochemical analysis with SARS-CoV-2 protein antibodies.</p></sec><sec><title>Results</title><p>Results. Among the patients with COVID-19 history higher levels of fT4 (13.6 [12.4; 15.5] vs 12.8 [11.0; 15.3] pmol/l, p = 0.046) and a lower proportion of patients with euthyroidism (122 (68.9%) vs 59 (80.8%), p = 0.037) were detected. In the main group there were more cytological samples with macrophages accumulations (16 (39.0%) vs 2 (10.0%), p = 0.017), however, immu-nocytochemical study did not reveal any SARS-Cov-2-positive samples. During the post-COVID-19 period, approximately 60% of patients with subclinical thyroid dysfunctions experienced spontaneous normalization. There were correlations between IgG SARS-Cov-2 levels and parameters characterizing the structural and functional state of the thyroid gland.</p></sec><sec><title>Conclusion</title><p>Conclusion. The most typical clinical feature of post-COVID-19 thyropathies was a smaller proportion of individuals with euthyroidism. Mild thyroid dysfunctions identified during the post-COVID-19 period tended to develop spontaneous normalization in 60% of cases. The immunocytochemical tests indicate the absence of SARS-Cov-2 persistence in the thyroid tissue. COVID-19- associated immunopathological reactions are involved in the pathogenesis of post-COVID-19 thyropathies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>анамнез COVID-19</kwd><kwd>тиреоидные заболевания</kwd><kwd>тонкоигольная аспирационная биопсия</kwd><kwd>иммуноцитохимический анализ</kwd><kwd>тиреоидный статус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>history of COVID-19</kwd><kwd>thyroid diseases</kwd><kwd>fine needle aspiration biopsy</kwd><kwd>immunocytochemical analysis</kwd><kwd>thyroid status</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">Chen W, Lei J, Li Z.
