Мы наблюдали 180 пациентов с установленным диагнозом «болезнь Крона» в течение 52 недель с последующей ретроспективной оценкой. Пациенты были разделены на три группы в зависимости от возраста начала заболевания согласно Парижской классификации (А1, А2, А3). На визитах проводились: сбор жалоб, анамнеза, объективный осмотр, клинический анализ крови; биохимический анализ крови (С-реактивный белок); фекальный кальпротектин; илеоколоноскопия с биопсией; морфологическое исследование биоптатов кишки. Статистическая обработка полученных данных проводилась с использованием программ Excel, RStudio и языка R, для категориальных данных использовались критерий χ2 Пирсона или точный тест Фишера (для таблиц 2 × 2 с малыми выборками). Для категориальных и количественных использовался t-test Манна — Уитни. Для проверки равенства средних значений использовался t-критерий Стьюдента.</p></sec><sec><title>Результаты</title><p>Результаты. Распределение по полу и средняя продолжительность болезни были сопоставимы во всех группах. На момент установления диагноза в группе А1 чаще выявлялся илеоколит (р = 0,01), воспалительная форма болезни Крона (р &lt; 0,05), поражение верхних отделов желудочно-кишечного тракта (р &lt; 0,05). В группе А3 преобладало изолированное поражение толстой кишки (р &lt; 0,001). Достоверного различия между группами в частоте встречаемости внекишечных проявлений болезни установлено не было (р = 0,32). В группе А1 отмечалась положительная корреляция между курением и отсутствием ответа на терапию. В группе А2 среди курильщиков чаще регистрировалось отсутствие эндоскопической ремиссии на момент окончания исследования (р &lt; 0,05). По характеру перианального поражения во всех группах отмечалось преобладание анальных трещин. В группе А1 отмечалась положительная корреляция между отсутствием перианального поражения и достижением клинической, лабораторной и эндоскопической ремиссии на момент окончания исследования. В группе А2 ухудшение по данным эндоскопического исследования наблюдалось чаще среди тех пациентов, кто заболел в возрасте до 30 лет (р = 0,01).</p></sec><sec><title>Выводы</title><p>Выводы. Не только детский возраст, но и начало болезни Крона в возрасте до 40 лет являются фактором риска прогрессирования болезни и более тяжелого ее течения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to evaluate the characteristics of Crohn's disea depending on the age of the disease onset in patients observed in a specialized City Center for Inflammatory Bowel Diseases Diagnosis and Treatment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We observed 180 patients with an established diagnosis of Crohn's disease for 52 weeks, followed by a retrospective assessment. Patients were divided into three groups depending on the age of the onset of the disease according to the Paris classification (A1, A2, A3). The visits included: the collection of complaints, medical history, objective examination, clinical blood testing; biochemical blood testing (C-reactive protein); fecal calprotectin; ileocolonoscopy. Statistical processing of the obtained data was carried out using Excel, RStudio and the R language; for categorical data, the Pearson chi-square test or Fisher's exact test was used (for 2 × 2 tables with small samples). For categorical and quantitative, the Mann – Whitney t-test was used. Student's t-test was used to test the equality of means.</p></sec><sec><title>Results</title><p>Results. The gender distribution and the average duration of the disease were comparable in all groups. At the time of diagnosis, ileocolitis (p = 0.01), inflammatory form of Crohn's disease (p &lt; 0.05), and the upper gastrointestinal tract involvement (p &lt; 0.05) were more frequently detected in group A1. Isolated colonic Crohn’s disease predominated in group A3 (p &lt; 0.001). No significant difference between the groups in the incidence of extraintestinal manifestations of the disease was found (p = 0.32). In group A1, there was a positive correlation between smoking and lack of response to therapy. In group A2, endoscopic remission was observed less frequently among smokers at the end of the study (p &lt; 0.05). Anal fissures were noted as the most common perianal disease in all groups. In group A1, there was a positive correlation between clinical, laboratory and endoscopic remission and the absence of perianal disease. At the end of the follow-up, the worsening of endoscopic SES-CD level was observed more frequently in the patients with the onset before 30 years old in group A2 (p = 0.01).</p></sec><sec><title>Conclusions</title><p>Conclusions. Not only pediatric onset, but also the onset of Crohn's disease before the age of 40 is a risk factor for the progression of the disease and its more severe course.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Крона</kwd><kwd>воспалительные заболевания кишечника</kwd><kwd>генно-инженерная биологическая терапия</kwd><kwd>возраст начала заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Crohn's disease</kwd><kwd>inflammatory bowel diseases</kwd><kwd>biological therapy</kwd><kwd>the age of the onset of Crohn’s disease</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">Torres J., Caprioli F., Katsanos K.H., Lobatón T., Micic D., Zerôncio M., et al.
