Рентгенологическое прогрессирование (РП) ревматоидного артрита (РА) – один из основных признаков заболевания и эффективности терапии. РП сопровождается увеличением количества эрозий, суженных суставных щелей, рентгенологической стадии (Rg-стадии).</p><p>Цель исследования – представить сравнительную характеристику больных ревматоидным артритом с быстрым и медленным темпом рентгенологического прогрессирования при длительном наблюдении.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В проспективное исследование с продолжительностью наблюдения 9,7±1,7 года включена 151 женщина в возрасте 53,9±9,2 года с РА. Всем больным проведено клиническое, лабораторное и рентгенологическое обследование. РП изучено с учетом изменения стадии РА по Steinbrocker, количества эрозий и степени сужения суставных щелей методом Sharp/van der Heijde (SVH).</p></sec><sec><title>Результаты</title><p>Результаты. Увеличение счета эрозий по SVH выявлено у 66 (53%) человек, суженных щелей – у 81 (65%) человека. Уменьшилось количество больных с Rg1, Rg2, Rg3; увеличилось – с Rg4: с 29 (19%) до 54 (36%) человек (p&lt;0,05). Медленное РП (Rg1–Rg2 на момент повторного обследования) отмечено у 63 (42%) человек, быстрое РП (исходно Rg1/Rg2, в динамике Rg3, или исходно Rg2/Rg3, в динамике Rg4) – у 32 (21%) человек. У 56 (37%) больных Rg-стадия не изменилась. Быстрое РП ассоциируется с меньшим возрастом при дебюте РА и при включении в исследование; большей длительностью РА; более высоким показателем матриксной металлопротеиназы 3 и уровнем интерлейкина 6 выше нормы в динамике; меньшей дозой метотрексата как в режиме монотерапии, так и в комбинации с другими средствами; более высокой средней суточной и кумулятивной дозой глюкокортикоидов.</p></sec><sec><title>Выводы</title><p>Выводы. Многолетнее проспективное исследование продемонстрировало РП, несмотря на достижение ремиссии и снижение активности РА у большинства пациентов. Выделение фенотипов больных РА с быстрым и медленным РП позволит обеспечить персонифицированный подход ведения пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Radiographic progression (RP) of rheumatoid arthritis (RA) is one of the main signs of the disease and a key factor in assessing the effectiveness of therapy. RP is accompanied by an increase in the number of erosions, narrowed joint spaces, and radiographic stage (Rg stage).</p><p>The aim – to compare the characteristics of patients with rheumatoid arthritis with rapid and slow rates of radiographic progression during long-term follow-up.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A prospective cohort study lasting 9.7±1.7 years included 151 women with RA aged 53.9±9.2 years. All patients underwent clinical, laboratory, and radiographic examinations. RP was analyzed taking into account changes in the Steinbrocker RA stage, the number of erosions, and the degree of joint space narrowing using the Sharp/van der Heijde (SVH) method.</p></sec><sec><title>Results</title><p>Results. An increase in the erosion count according to SVH was detected in 66 (53%) patients, and narrowed clefts – in 81 (65%) patients. The number of patients with Rg1, Rg2, and Rg3 decreased; those with Rg4 increased from 29 (19%) to 54 (36%) people (p&lt;0.05). Slow RP (Rg1–Rg2 in dynamics) was observed in 63 (42%) patients, and rapid RP (increase in Rg stage) – in 32 (21%) patients. In 56 (37%) patients, the Rg stage did not change.</p><p>Rapid RP is associated with a younger age at RA onset and inclusion in the study, with a longer duration of RA, with a higher matrix metallopeptidase 3 index and interleukin 6 level above normal in dynamics, with a lower dose of methotrexate both in monotherapy and in combination with other agents; with a higher average daily and cumulative dose of glucocorticoids.</p></sec><sec><title>Conclusions</title><p>Conclusions. A long-term prospective study demonstrated RP despite achieving remission and decreasing activity in the majority of RA patients. The rate of RP depends on many factors, both RA-related and non-RA-related. Distinguishing phenotypes of RA patients with rapid and slow RP will enable a personalized approach to patient management.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>проспективное многолетнее наблюдение</kwd><kwd>рентгенологическая стадия ревматоидного артрита</kwd><kwd>рентгенологическое прогрессирование ревматоидного артрита</kwd><kwd>счет эрозий и суженных щелей методом Sharp/van der Heijde</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>prospective long-term observation</kwd><kwd>radiographic stage of rheumatoid arthritis</kwd><kwd>radiographic progression of rheumatoid arthritis</kwd><kwd>counting erosions and narrowed spaces using the Sharp method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания по выполнению фундаментальных научных исследований ФГБНУ НИИР им.
