Было установлено, что пациенты ревматологического профиля имеют повышенный риск заражения и тяжелого течения НКИ и что терапия ИВРЗ также влияет на исходы заболевания. В частности, использование анти-В-клеточного препарата ритуксимаб (РТМ) ассоциировано с более высоким риском тяжелого течения НКИ и повышенной летальностью. Пандемия COVID-19 показала необходимость поиска альтернативных и безопасных вариантов лечения таких пациентов. Настоящая работа является продолжением 12-недельного исследования эффективности и безопасности терапии препаратом олокизумаб (ОКЗ) у пациентов с ревматоидным артритом (РА) после переключения с анти-B-клеточной терапии в условиях пандемии SARS-CoV-2.</p><p>   Цель исследования – оценить эффективность и безопасность препарата ОКЗ (Артлегиа®; раствор для подкожного введения, 160 мг/мл – 0,4 мл) у пациентов с РА в условиях реальной клинической практики после переключения с РТМ в условиях пандемии COVID-19.</p><sec><title>   Материал и методы</title><p>   Материал и методы. В исследование включено 19 пациентов с подтвержденным диагнозом РА, не менее 6 мес назад получавших РТМ в дозе 500–1000 мг дважды с интервалом в 14 дней. По мере повышения активности заболевания РТМ заменяли на ОКЗ на фоне продолжения терапии синтетическими базисными противовоспалительными препаратами. На неделях 0, 4, 8, 12 и 24 после смены генно-инженерного биологического препарата определяли число болезненных (ЧБС) и припухших (ЧПС) суставов из 28, интенсивность боли по визуальной аналоговой шкале, СОЭ, уровень СРБ, индексы активности заболевания CDAI, DAS28-СОЭ, DAS28-СРБ, индекс HAQ, во время каждого визита оценивали профиль безопасности терапии.</p><p>   Результаты и обсуждение. После 4, 8, 12 и 24 нед введения ОКЗ отмечено статистически значимое снижение медианы ЧБС (с 10 до 6,0; 3,0; 5,0 и 4,0 соответственно; p &lt; 0,05) и ЧПС (с 7,0 до 3,0 к неделе 4 и до 2,0 к неделям 8, 12 и 24; p &lt; 0,05). В эти же сроки наблюдалось и уменьшение уровня СРБ и СОЭ. Медиана СРБ снизилась с 18 до 0,6 мг/л к неделе 4 и до 0,5 мг/л к неделям 8, 12 и 24 (p &lt; 0,05), СОЭ – с 30 до 5 мм/ч в каждом исследованном периоде (p &lt; 0,05). Уровень СРБ нормализовался к неделе 4 независимо от исходных значений. Все индексы активности РА продемонстрировали положительную динамику, начиная с недели 4, в каждом оценочном периоде по сравнению с исходными результатами. После недель 4, 8, 12 и 24 медиана DAS28-СОЭ уменьшилась с 5,50 до 3,57; 3,30; 3,08 и 3,01 (p &lt; 0,05); DAS28-СРБ – с 5,30 до 3,46; 3,23; 3,26 и 3,12 (p &lt; 0,05); CDAI – с 27,0 до 17,0; 12,0; 15,0 и 12,0 соответственно (p &lt; 0,05). У всех пациентов зафиксировано уменьшение боли уже к неделе 4 наблюдения. Статистически значимое улучшение функционального статуса отмечалось после недели 4 терапии и сохранялось до недели 24. Медиана индекса HAQ уменьшилась с 1,62 до 1,50 на неделях 4, 8 и 12 и до 1,12 к неделе 24 (p &lt; 0,05).</p></sec><sec><title>   Заключение</title><p>   Заключение.

It has been shown that rheumatological patients have an increased risk of infections and a severe course of NCI and that IIRD therapy also influences the disease outcomes. In particular, the use of the anti-B-cell medication rituximab (RTM) is associated with a higher risk of severe NCI and increased mortality. The COVID-19 pandemic has highlighted the need to find alternative and safe treatment options for these patients. This work is the continuation of a 12-week study on the efficacy and safety of olok-izumab (OKZ) therapy in patients with rheumatoid arthritis (RA) after switching from anti-B-cell therapy during the SARS-CoV-2 pandemic.</p><sec><title>   Objective</title><p>   Objective: to evaluate the efficacy and safety of OKZ (Artlegia®; solution for subcutaneous administration, 160 mg/ml – 0.4 ml) for the treatment of patients with RA in real-life clinical practice after switching from RTM during the COVID-19 pandemic.</p></sec><sec><title>   Material and methods</title><p>   Material and methods. The study included 19 patients with a confirmed diagnosis of RA who had received RTM at a dose of 500–1000 mg twice every 14 days at least 6 months ago. As disease activity increased, RTM was replaced with OKZ while therapy with synthetic disease-modifying anti-rheumatic drugs (DMARDs) was continued. At weeks 0, 4, 8, 12 and 24 after switching the biologic DMARD, the number of tender (TJN) and swollen (SJN) joints out of 28, pain intensity on a visual analogue scale, ESR, CRP level, disease activity indices CDAI, DAS28-ESR, DAS28-CRP, HAQ index and the safety profile of the therapy were assessed at each visit.</p><p>   Results and discussion. After 4, 8, 12 and 24 weeks of OKZ administration, there was a statistically significant decrease in mean TJN (from 10 to 6.0, 3.0, 5.0 and 4.0, respectively; p &lt; 0.05) and SJN (from 7.0 to 3.0 by week 4 and to 2.0 by weeks 8, 12 and 24; p &lt; 0.05). At the same time, a decrease in CRP and ESR values was also observed: median CRP decreased from 18 to 0.6 mg/l by week 4 and to 0.5 mg/l by weeks 8, 12 and 24 (p &lt; 0.05), ESR from 30 to 5 mm/h in each study period (p &lt; 0.05). CRP levels normalized by week 4, regardless of baseline values. All RA activity indices showed a positive dynamic compared to baseline values from week 4 onwards in each assessment period. After weeks 4, 8, 12 and 24, the median DAS28-ESR decreased from 5.50 to 3.57; 3.30; 3.08 and 3.01 (p &lt; 0.05); DAS28-CRP – from 5.30 to 3.46; 3.23; 3.26 and 3.12 (p &lt; 0.05); CDAI – from 27.0 to 17.0; 12.0; 15.0 and 12.0 (p &lt; 0.05), respectively. All patients showed a decrease in pain by the 4th week of observation. A statistically significant improvement in functional status was observed after the 4th week of therapy and was maintained until week 24. The median HAQ index decreased from 1.62 to 1.50 at weeks 4, 8 and 12 and to 1.12 at week 24 (p &lt; 0.05).</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The study showed that the non-medical switch from RTM to OKZ during the COVID-19 pandemic was effective and safe.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>COVID-19</kwd><kwd>олокизумаб</kwd><kwd>ритуксимаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>COVID-19</kwd><kwd>olokizumab</kwd><kwd>rituximab</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках государственного задания НИИКЭЛ – филиала ИЦиГ СО РАН (проект № FWNR-2023- 0009).
