Язвенный колит (ЯК) — это хроническое воспалительное заболевание, характеризующееся чередованием периодов обострения и ремиссии, что требует точной оценки активности патологического процесса для определения тактики лечения. Хотя эндоскопическое исследование остается «золотым стандартом» оценки воспаления слизистой оболочки, его инвазивный характер ограничивает возможность частого применения. Индекс системного иммунного воспаления (SII), рассчитываемый на основе рутинного общего анализа крови, рассматривается как перспективный неинвазивный биомаркер системного воспаления.</p></sec><sec><title>Цель</title><p>Цель: оценить роль индекса SII в определении активности и тяжести течения заболевания у пациентов с ЯК.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В данное одномоментное (кросс-секционное) исследование были включены 80 взрослых пациентов с ЯК, проходивших лечение в больницах Университета Айн-Шамс. В один и тот же день всем пациентам проводились клиническое обследование, лабораторные тесты (определение уровня С-реактивного белка, фекального кальпротектина и общий анализ крови), а также колоноскопия с оценкой по эндоскопическому индексу Мейо (Mayo Endoscopic Subscore). Индекс SII рассчитывали по формуле: (число тромбоцитов × число нейтрофилов) / число лимфоцитов.</p></sec><sec><title>Результаты</title><p>Результаты. Из 80 пациентов 25 (31,25 %) находились в стадии ремиссии, а 55 (68,75 %) имели активную форму заболевания. Значения SII были значимо выше у пациентов с активной формой ЯК по сравнению с лицами в стадии ремиссии (1357,97 ± 831,17 vs. 582,86 ± 188,88; p &lt; 0,001). Выявлена прямая корреляция SII с уровнями С-реактивного белка и фекального кальпротектина и обратная — с числом лимфоцитов. При пороговом значении (cutoff) &gt; 838,76 индекс SII позволял дифференцировать активную форму заболевания от ремиссии с чувствительностью 70,91 %, специфичностью 96,00 % и точностью 86,13 %. Пороговое значение &gt; 1148,67 позволяло отличить среднетяжелое и тяжелое течение заболевания от легкой формы с точностью 78,00 %.</p></sec><sec><title>Заключение</title><p>Заключение. Индекс SII является простым, экономически доступным и надежным неинвазивным маркером для оценки активности и тяжести течения язвенного колита. Его внедрение в практику рутинного мониторинга может снизить потребность в частом проведении эндоскопических исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Ulcerative colitis (UC) is a chronic inflammatory disease characterized by relapsing episodes that require accurate evaluation of disease activity to guide therapeutic decisions. Although endoscopy remains the gold standard for assessing mucosal inflammation, its invasive nature limits frequent use. The serum immune-inflammation index (SII), derived from routine blood counts, has emerged as a potential non-invasive biomarker of systemic inflammation.</p></sec><sec><title>Aim</title><p>Aim: to evaluate the role of SII in assessing disease activity and severity in UC patients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. This cross-sectional study included 80 adult UC patients attending Ain Shams University Hospitals. Clinical evaluation, laboratory testing (C-reactive protein, fecal calprotectin, and complete blood count), and colonoscopic assessment using the Mayo Endoscopic Subscore were performed on the same day. SII was calculated as (platelet count × neutrophil count) / lymphocyte count.</p></sec><sec><title>Results</title><p>Results. Of the 80 patients, 25 (31.25 %) were in remission and 55 (68.75 %) had active disease. SII values were significantly higher in patients with active UC compared to those in remission (1357.97 ± 831.17 vs. 582.86 ± 188.88; p &lt; 0.001). SII positively correlated with C-reactive protein and fecal calprotectin, and negatively with lymphocyte count. At a cutoff of &gt; 838.76, SII discriminated active disease from remission with 70.91 % sensitivity, 96.00 % specificity, and 86.1 % accuracy. A cutoff of &gt; 1148.67 distinguished moderate-to-severe from mild disease with 78.00 % accuracy.</p></sec><sec><title>Conclusion</title><p>Conclusion. The SII is a simple, cost-effective, and reliable non-invasive marker for assessing disease activity and severity in UC. Its incorporation into routine monitoring may reduce dependence on frequent endoscopic evaluation. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>индекс системного иммунного воспаления сыворотки крови</kwd><kwd>язвенный колит</kwd><kwd>эндоскопический индекс Мейо</kwd><kwd>С-реактивный белок</kwd><kwd>фекальный кальпротектин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Serum Immune-Inflammation Index</kwd><kwd>Ulcerative Colitis</kwd><kwd>Mayo Endoscopic Sub-score</kwd><kwd>CRP</kwd><kwd>Fecal Calprotectin</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы выражают благодарность сотрудникам отделения гастроэнтерологии и гепатологии больницы Университета Айн-Шамс (Каир, Египет).</funding-statement><funding-statement xml:lang="en">the authors express their gratitude to the members of the Gastroenterology and Hepatology Unit at Ain Shams University Hospital, Cairo, Egypt.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Li P., Wu Y., Xiong W., Cao J., Chen M., Yuan Z., et al.
