Existing targeted anti-IL-5 drugs can improve the clinical and functional parameters in patients with a combination of severe asthma and CRSwNP.</p> <p><bold><italic>AIM</italic></bold><italic>:</italic> To evaluate mepolizumab efficacy in patients with nonallergic severe asthma and concomitant inflammatory nasal diseases in real clinical practice.</p> <p><bold><italic>MATERIALS AND METHODS</italic></bold><italic>:</italic> The study was conducted without a control group, by comparing related populations (before–after analysis) and based on the Sverdlovsk regional register of adult patients with severe asthma and concomitant inflammatory nasal diseases. The primary endpoints were asthma control achievement (ACT questionnaire) and a decrease in the proportion of patients with uncontrolled severe asthma. The number of asthma exacerbations, emergency calls and hospitalizations, quality of life according to the AQLQ questionnaire, peripheral blood eosinophil level, and respiratory function (the volume of forced exhalation in the first second, the forced vital capacity of the lungs, as well as the ratio of these parameters) were also assessed. The dynamics of nasal symptoms was assessed using the SNOT-22 questionnaire and visual analog scale.</p> <p><bold><italic>RESULTS</italic></bold><italic>:</italic> During 12 months of therapy with mepolizumab, the ACT score increased from 9 (Q1–Q3, 7–11) to 22 (Q1–Q3, 21–24) points (<italic>p</italic> &lt;0.001). The proportion of patients with uncontrolled asthma decreased from 100% to 10% (<italic>p</italic> &lt;0.001). The number of asthma exacerbations decreased from 3.18±2.8 per patient per year to 0 (<italic>p</italic> &lt;0.001), and that of hospitalizations decreased from 0.57±0.9 per patient per year to 0 (<italic>p</italic>=0.007). The quality of life according to the AQLQ increased from 3.48±1.05 (95% CI, 2.73–4.24) to 5.59±0.88 points (95% CI, 4.96–6.22) (<italic>p</italic> &lt;0.001). The number of blood eosinophils decreased from 442 (Q1–Q3, 336–853) to 90 (Q1–Q3, 73–117) cells/µL (<italic>p</italic> &lt;0.001). There was increase in FEV<sub>1</sub> from 63.9%±24.2% (95% CI, 46.6–81.2) to 80.5%±18.3% (95% CI, 67.4–93.6) (<italic>p</italic>=0.015). Decreases in the SNOT-22 questionnaire score by 33 points, from 45±30 to 22±15 (<italic>p</italic>=0.006), and in the visual analog scale score by 5 points, from 8 (Q1–Q3, 5–8) to 3 (Q1–Q3, 3–5) (<italic>p</italic>=0.017), were also noted.</p> <p><bold><italic>CONCLUSIONS</italic></bold><italic>:</italic> Based on the study results, there were asthma control improvement, a decrease in asthma exacerbations, and quality of life improvement according to the AQLQ. A statistically significant decrease in the number of peripheral blood eosinophils and respiratory function improvement were also revealed. In patients with concomitant inflammatory nasal diseases, significant improvement in nasal breathing was noted, which was confirmed by the scores of the SNOT-22 questionnaire and visual analog scale.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование</italic></bold><italic>.</italic> Т2-воспаление лежит в основе неаллергической, эозинофильной тяжёлой бронхиальной астмы и хронического полипозного риносинусита. Существующие таргетные препараты, направленные против IL-5, могут улучшать клинико-функциональные показатели у пациентов с сочетанием тяжёлой астмы и хронического полипозного риносинусита.</p> <p><bold><italic>Цель</italic></bold> ― оценить эффективность меполизумаба у пациентов с неаллергической тяжёлой бронхиальной астмой и сопутствующими воспалительными заболеваниями носа в реальной клинической практике.</p> <p><bold><italic>Материалы и методы</italic></bold><italic>.</italic> Исследование проводилось без контрольной группы, методом сравнения связанных совокупностей (анализ «до-после») на основе Свердловского областного регистра взрослых пациентов с тяжёлой бронхиальной астмой и сопутствующими воспалительными заболеваниями носа. В качестве первичной конечной точки оценивали достижение контроля над астмой (опросник АСТ) и уменьшение доли пациентов с неконтролируемой тяжёлой астмой. Оценивали также количество обострений астмы, вызовов скорой медицинской помощи и госпитализаций, качество жизни по опроснику AQLQ, уровень эозинофилов периферической крови, функцию внешнего дыхания (объём форсированного выдоха за первую секунду, форсированную жизненную ёмкость лёгких, а также соотношение этих параметров). Динамика состояния пациентов с воспалительными заболеваниями носа оценивалась по опросникам SNOT-22 и ВАШ.</p> <p><bold><italic>Результаты</italic></bold><italic>.</italic> За 12 мес терапии меполизумабом АСТ увеличился с 9 (Q1–Q3: 7–11) до 22 (Q1–Q3: 21–24) баллов (<italic>p &lt;</italic>0,001). Доля пациентов с неконтролируемой астмой снизилась со 100 до 10% (<italic>p &lt;</italic>0,001). Снизилось количество обострений астмы с 3,18±2,8 случая на пациента в год до 0 (<italic>р &lt;</italic>0,001) и госпитализаций с 0,57±0,9 до 0 (<italic>р</italic>=0,007). Качество жизни по AQLQ повысилось с 3,48±1,05 (95% ДИ 2,73–4,24) до 5,59±0,88 (95% ДИ 4,96–6,22) баллов (<italic>р &lt;</italic>0,001). Количество эозинофилов крови снизилось с 442 (Q1–Q3: 336–853) до 90 кл/мкл (Q1–Q3: 73–117) (<italic>p &lt;</italic>0,001). Наблюдалось увеличение ОФВ<sub>1</sub> с 63,9±24,2% (95% ДИ 46,6–81,2) до 80,5±18,3% (95% ДИ 67,4–93,6) (<italic>p=</italic>0,015). По опроснику SNOT-22 получено снижение на 33 пункта ― с 45±30 до 22±15 (<italic>p=</italic>0,006), по ВАШ ― на 5 баллов: с 8 (Q1–Q3: 5–8) до 3 (Q1–Q3: 3–5) (<italic>p=</italic>0,017).</p> <p><bold><italic>Заключение</italic></bold><italic>.</italic> По результатам исследования наблюдались улучшение контроля над астмой, уменьшение количества обострений бронхиальной астмы, улучшение качества жизни по AQLQ. Выявлено также статистически значимое снижение уровня эозинофилов в периферической крови и улучшение функции внешнего дыхания. Со стороны сопутствующих воспалительных заболеваний носа отмечалось существенное улучшение носового дыхания, подтверждаемое данными опросников SNOT-22 и ВАШ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>severe bronchial asthma</kwd><kwd>chronic rhinosinusitis with nasal polyposis</kwd><kwd>targeted therapy</kwd><kwd>biologicals</kwd><kwd>mepolizumab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тяжёлая бронхиальная астма</kwd><kwd>хронический полипозный риносинусит</kwd><kwd>иммунобиологическая терапия</kwd><kwd>генно-инженерные биофармацевтические препараты</kwd><kwd>меполизумаб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Global Initiative for Asthma.
