В современных условиях постковидный синдром (ПКС) характеризуется клинической гетерогенностью и мультиорганностью поражения, нередко представляя собой дифференциально-диагностическую и терапевтическую проблему. Однако в большинстве исследований ПКС стратификация пациентов с учетом отдельных коморбидных состояний не выполнялась. Так, оценке течения ПКС при ревматических заболеваниях посвящено крайне малое число исследований.Цель. Охарактеризовать особенности течения COVID-19 у пациентов с ревматоидным артритом, а также провести сравнительную оценку клинико-демографических показателей в группах пациентов с ревматоидным артритом, дифференцированных по наличию ПКС.Материалы и методы. Изучен материал опросника, содержавшего вопросы, касающиеся социодемографических данных респондентов, информацию о ревматологическом анамнезе, коморбидных заболеваниях, данные о перенесенном COVID-19, включая случаи повторного заражения, и о ПКС.Результаты. В исследование включено 32 взрослых пациента (29 женщин, 90%) с достоверным диагнозом ревматоидного артрита (РА), перенесших COVID-19. В 23 случаях была возможность сформировать суждение о наличии или отсутствии ПКС. Для изучения ПКС 23 пациента были стратифицированы на две группы: 11 (47,8%) пациентов отмечали развитие ПКС (1-я группа) и 12 перенесли COVID-19 без последствий (2-я группа). Обе группы были представлены преимущественно женщинами (90,9% и 91,7% соответственно). В общей группе 37,5% пациентов с COVID-19 потребовалось стационарное лечение. Количество симптомов, ассоциированных с COVID-19, не коррелировало с активностью РА. Однако пациенты с более высокой активностью РА чаще отмечали усиление артралгии как симптома COVID-19. 47,8% пациентов, перенесших COVID-19, испытывали ПКС. Средний возраст, количество коморбидных заболеваний и выраженность симптомов РА на момент COVID-19 были сравнительно выше в группе пациентов с РА и ПКС. Пациенты с ПКС также отмечали более высокую частоту госпитализаций и более тяжелое течение COVID-19.Выводы. Необходима количественная оценка риска развития ПКС, которая послужит базой для разработки стратегии, направленной на профилактику, своевременную диагностику и лечение данного синдрома у больных РЗ. С этой целью требуются дальнейшие исследования на более объемных когортах пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. In modern reality postcovid syndrome (PCS) is characterized by clinical heterogeneity and multi-organ involvement, often presenting a differential diagnostic and therapeutic problem. However, in most studies of PCS, stratification of patients taking into account individual comorbid conditions was not performed. Thus, only an extremely small number of studies have been devoted to assessing the course of PCS in rheumatic diseasesPurpose. To characterize the features of the course of COVID-19 in patients with rheumatoid arthritis, as well as to conduct a comparative assessment of clinical and demographic parameters in groups of patients with rheumatoid arthritis, differentiated by the presence of PCS.Materials and methods. The material of the questionnaire which contained questions regarding socio-demographic data of respondents, information on rheumatological history, comorbid diseases, data on past COVID-19, including cases of re-infection, and PCS.Results.The study included 32 adult patients (29 women, 90%) with a reliable diagnosis of rheumatoid arthritis. Of the 32 patients who underwent COVID-19, in 23 cases it was possible to form a judgment about the presence or absence of PCS. To study PCS, 23 patients were stratified into two groups: 11 (47.8%) patients developed PCS (Group 1) and 12 patients had COVID-19 without consequences (Group 2). Both groups were represented predominantly by women (90.9% and 91.7%, respectively). In the general group 37.5% of patients with COVID-19 required inpatient treatment. The number of symptoms associated with COVID-19 did not correlate with RA activity, however, patients with higher RA activity were more likely to report increased arthralgia as a symptom of COVID-19. 47.8% of COVID-19 survivors experienced PCS. The average age, the number of comorbid diseases and the severity of RA symptoms at the time of COVID-19 were relatively higher in the group of patients with RA and PKS. Patients with PKS also noted a higher frequency of hospitalizations and a more severe course of COVID-19.Conclusions. A quantitative assessment of the risk of developing PKS is needed, which will serve as a basis for developing a strategy aimed at prevention, timely diagnosis and treatment of this syndrome in patients with RS. To this end, further studies on larger cohorts of patients are required.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>ревматоидный артрит</kwd><kwd>иммуновоспалительные ревматические заболевания</kwd><kwd>постковидный синдром</kwd><kwd>лонг-ковид</kwd><kwd>артралгия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>rheumatoid arthritis</kwd><kwd>long COVID</kwd><kwd>immunoinflammatory rheumatic disease</kwd><kwd>post COVID-19 condition</kwd><kwd>post-COVID-19 syndrome</kwd><kwd>arthralgia</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках научно-исследовательской работы ФГБНУ «Научно-исследовательский институт ревматологии имени В.А.
