В исследование включено 117 пациентов с РА по критериям ACR/EULAR 2010 г. (средний возраст — 54,8+14,8 года), находившихся на обследовании и лечении в ФГБНУНИИР им. В.А. Насоновой в 2018—2019 гг. Медиана длительности болезни составила 5,0[1,5; 9,5]лет, среднее значение DAS28 — 5,0+1,3. Проанализированы документация и данные анамнеза с акцентом на сопутствующие заболевания. Для оценки профиля мультиморбидной патологии использовался кумулятивный индекс заболеваний CIRS (Cumulative Illness Rating Scale).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Пациенты с РА имели высокий показатель спектра мультиморбидной патологии — сопутствующая патологии выявлена в 96 (82%) случаях. Медиана количества заболеваний у одного пациента — 2 [1; 4], среднее значение общего счета CIRS — 6,7±3,3 балла, медиана — 2,5 [1; 6]. Число сопутствующих заболеваний, вынесенных в диагноз до использования CIRS, было значительно меньше (на 48%; р&lt;0,01), чем выявлено в проведенном исследовании. Наиболее часто в изучаемой когорте не диагностировалась хроническая болезнь почек, которая встречалась практически в половине наблюдений (42,5%), в среднем у каждого 3-го пациента не были обнаружены признаки метаболического синдрома (гипергликемия — у 29%, ожирение — у 13,5%) и хронической гипоксии (анемия, впервые вынесенная в диагноз, верифицирована в 24% случаев). Обнаружена корреляция количественного эквивалента мультиморбидности со значениями клинико-лабораторных показателей активности РА, включая число болезненных суставов (r=0,39;р&lt;0,001), общую оценку больного (r=0,37;р=0,03), общую оценку активности болезни врачом (r=0,37; р&lt;0,01), индексы DAS28 (r=0,42;р&lt;0,001), CDAI (r=0,37;р&lt;0,001), SDAI (r=0,34;р&lt;0,001), HAQ (r=0,34;р&lt;0,001). Значение общего счета CIRS не различалось у пациентов с ранней и с развернутой или поздней стадиями заболевания: 6,6±3,5 и 6,7±3,3 соответственно (р=0,9).</p></sec><sec><title>Выводы</title><p>Выводы. Систематический скрининг мультиморбидности должен выполняться у всех пациентов с РА. Для оценки распространенности мультиморбидности и ее последствий целесообразно использовать шкалу CIRS.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the presence and nature of multimorbidity in patients with rheumatoid arthritis (RA) and the impact of multimorbidity on disease activity.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The investigation enrolled 117 patients (mean age, 54.8+14.8years) with RA according to the 2010 ACR/EULAR criteria, who had been examined and treated at the V.A. Nasonova Research Institute of Rheumatology in 2018—2019. The median disease duration was 5.0 [1.5; 9.5] years; the mean DAS28 score was 5.0+1.3. Documentation and anamnesis data were analyzed with emphasis on associated diseases. The Cumulative Illness Rating Scale (CIRS) was used to assess the profile of multimorbidity.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The patients with RA had a high index of the spectrum of multimorbidity; comorbidity was detected in 96 (82%) cases. The median number of diseases in one patient was 2 [1; 4], the mean total CIRS score was 6.7+3.3; the median value was 2.5 [1; 6]. The number of comorbidities diagnosed before using the CIRS was significantly fewer (by 48%; p&lt;0.01) than was found in the investigation conducted. Chronic kidney disease that occurred in almost half (42.5%) of cases was most commonly undiagnosed in the cohort under study; on average, every three patients were not found to have signs of metabolic syndrome (hyperglycemia in 29% and obesity in 13.5%) and chronic hypoxia (new-onset anemia verified in 24% of cases). There was a correlation of the quantitative equivalent of multimorbidity with the clinical and laboratory measures of RA activity, including the number of painful joints (r = 0.39; p&lt;0.001), overall patient assessment (r=0.37; p=0.03),physician's global assessment of disease activity (r = 0.37; p &lt; 0.01), DAS28 (r = 0.42; p&lt;0.001), CDAI (r=0.37; p&lt;0.001), SDAI (r=0.34; p&lt; 0.001), HAQ (r=0.34;p&lt;0.001). The total CIRSscore did not differ in patients with early- and advanced- or end-stage RA: 6.6+3.5 and 6.7+3.3, respectively (p=0.9).</p></sec><sec><title>Conclusion</title><p>Conclusion. A systematic screening of multimorbidity should be carried out in all patients with RA. It is advisable to use the CIRS to estimate the prevalence of multimorbidity and its consequences.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>активность</kwd><kwd>мультиморбидность</kwd><kwd>CIRS</kwd><kwd>коморбидность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>activity</kwd><kwd>multimorbidity</kwd><kwd>CIRS</kwd><kwd>comorbidity</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">Radner H, Yoshida K, Smolen JS, et al.
