The pathophysiological mechanisms of the interaction between asthma and obesity have attracted considerable attention.</p> <p><bold>AIM:<italic> </italic></bold>The work aimed to assess the characteristics of the cytokine profile in patients with asthma and obesity depending on the time of asthma onset.</p> <p><bold>METHODS:<italic> </italic></bold>A total of 180 individuals were examined: 150 patients with asthma of varying severity were stratified by body mass index and divided into two study groups: those with a body mass index of 18.5–25 kg/m<sup>2</sup> (<italic>n</italic> = 52, Asthma group) and those with a body mass index of 30–35 kg/m<sup>2</sup> (<italic>n</italic> = 98). The control group consisted of 30 individuals. Patients with asthma and obesity (body mass index &gt; 30 kg/m<sup>2</sup>) were further subdivided into two groups according to the time of asthma onset: Obesity + Asthma and Asthma + Obesity (with asthma duration of approximately 10 years). Asthma severity was assessed using the Asthma Control Test (ACT) and the Asthma Control Questionnaire (ACQ-5). Spirometry with bronchodilator testing was performed, and venous blood was collected to determine cytokine profile parameters (tumor necrosis factor-alpha; interleukins IL-2, IL-4, IL-6, IL-8, IL-10, IL-17; interferon-gamma) and markers of systemic inflammation (C-reactive protein, fibrinogen).</p> <p><bold>RESULTS:<italic> </italic></bold>The asthma–obesity phenotype was characterized by a more severe course and poorer disease control, with the Obesity + Asthma group showing the most pronounced bronchial obstruction. Analysis of the cytokine profile revealed a significant imbalance between proinflammatory and anti-inflammatory cytokines, most pronounced in the Obesity + Asthma group. The findings underscore the importance of determining cytokine ratio indices with opposing activities (IL-2/IL-4, IL-2/IL-10, IL-8/IL-10, IL-6/IL-10, tumor necrosis factor-alpha/IL-10) to assess the severity of the inflammatory process and guide treatment strategies.</p> <p><bold>CONCLUSION:<italic> </italic></bold>Obesity contributes to the development and maintenance of systemic inflammation, aggravating the course and progression of asthma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Бронхиальная астма (БА) — сложное гетерогенное полиэтиологическое хроническое заболевание. Представляют интерес патофизиологические механизмы взаимодействия БА и ожирения.</p> <p><bold>Цель. </bold>Оценить особенности цитокинового профиля у больных БА в сочетании с ожирением в зависимости от времени дебюта астмы.</p> <p><bold>Методы. </bold>Обследовано 180 человек: 150 больных БА различной степени тяжести, разделённых с учётом индекса массы тела, составили две группы исследования: с индексом массы тела от 18,5 до 25 кг/м<sup>2</sup> (<italic>n</italic>=52) — «БА»; с индексом массы тела от 30 до 35 кг/м<sup>2</sup> (<italic>n</italic>=98). Группу контроля составили 30 человек. Далее пациенты с астмой в сочетании с ожирением (индекс массы тела &gt;30 кг/м<sup>2</sup>) были разделены на две группы в зависимости от времени дебюта астмы: «Ожирение + БА»; «БА + ожирение» (с давностью БА около 10 лет). В процессе исследования оценивали степень тяжести БА с использованием теста по контролю над астмой (ACT) и опросника по контролю симптомов астмы (ACQ-5), проводили спирографию с бронхолитической пробой, выполняли забор венозной крови для определения показателей цитокинового профиля (фактора некроза опухоли альфа; интерлейкинов — ИЛ-2, 4, 6, 8, 10, 17; интерферона гамма), маркеров системного воспаления (С-реактивный белок, фибриноген).</p> <p><bold>Результаты. </bold>Фенотип БА в сочетании с ожирением характеризовался более тяжёлым течением и худшим контролем заболевания, причём в группе «Ожирение + БА» отмечались наиболее выраженные нарушения бронхиальной проходимости. При анализе цитокинового профиля в исследуемых группах был отмечен значимый дисбаланс провоспалительных и противовоспалительных цитокинов, наиболее выраженным он оказался в группе «Ожирение + БА». Полученные данные подчёркивают важность определения индекса соотношения цитокинов с противоположной активностью (ИЛ-2/ИЛ-4, ИЛ-2/ИЛ-10, ИЛ-8/ИЛ-10, ИЛ-6/ИЛ-10, фактор некроза опухоли альфа/ИЛ-10) для оценки степени выраженности воспалительного процесса и дальнейшей тактики лечения пациентов.</p> <p><bold>Заключение. </bold>Ожирение способствует формированию и поддержанию системного воспаления, усугубляя течение и прогрессирование БА.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bronchial asthma</kwd><kwd>obesity</kwd><kwd>systemic inflammation</kwd><kwd>cytokines</kwd><kwd>asthma onset</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бронхиальная астма</kwd><kwd>ожирение</kwd><kwd>системное воспаление</kwd><kwd>цитокины</kwd><kwd>дебют астмы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lambrecht BN, Hammad H, Fahy JV.
