Материалы и методы:152 больным ВЗК (болезнь Крона и язвенный колит) был проведен водородный дыхательный тест (ВДТ) для верификации СИБР на аппарате «Gastro+» с использованием лактулозы. У всех больных оценивалась характеристика течения ВЗК, включающая 60 параметров: время постановки диагноза ВЗК, имеющиеся симптомы, оцениваемые по визуально аналоговой шкале (ВАШ), внекишечные проявления, текущее и предыдущее лечение, тяжесть атаки, протяженность поражения при ЯК, фенотипический вариант при БК, уровень эндоскопической активности, наличие или отсутствие хирургических вмешательств, показатели лабораторных и инструментальных методов обследования и др. Результаты. Частота положительного водородного дыхательного теста составила 48%, у больных БК - 50.7% (n=36), у больных ЯК - 45.7% (n=37) (р= 0.626). Наличие СИБР в целом у больных ВЗК было ассоциировано с уровнем клинической и эндоскопической активности и формой заболевания, тяжестью атаки; а также у больных ЯК - протяженностью поражения толстой кишки, у больных БК - наличием пенентрирующего и стенозирующего фенотипов. Больные ВЗК с наличием СИБР жалуются на большее число дефекаций, более низкий индекс массы тела, наличие снижения массы тела в течение 1 месяца до обследования и более частые жалобы на вздутие, флатуленцию, плаксивость и слабость. Таким образом, водородный дыхательный тест может использоваться для дифференциальной диагностики обострения ВЗК от клинических проявлений, вызванных СИБР.</p></abstract><trans-abstract xml:lang="en"><p>Research objective: to study the frequency of small intestinal bacterial overgrowth (SIBO) and factors associated with it in patients with inflammatory bowel diseases (IBD). Materials and methods of the study: 152 patients with IBD (Crohn’s disease and ulcerative colitis) a hydrogen breathing test (HBT) with lactulose, performed by the “Gastro+” monitor using lactulose. In all patients, the characteristics of the course of IBD were evaluated, including 60 parameters: the time of diagnosis of IBD, the existing symptoms assessed by a visually analog scale (VAS), extra-intestinal manifestations, current and previous treatment, severity of attack, extent of the lesion in UC, phenotypic variant in CD, the level of endoscopic activity, the presence or absence of surgical interventions, indicators of laboratory and instrumental methods of examination, etc. Results. The frequency of positive hydrogen breath test was 48%, in patients with CD - 50.7% (n=36), in patients with UC - 45.7% (n=37) (p= 0.626). The presence of SIBO in general in IBD patients was associated with the level of clinical and endoscopic activity and the form of the disease, the severity of the attack; as well as in UC patients - the extent of the colon lesion, in CD patients - the presence of penenting and stenosing phenotypes. Patients with IBD with the presence of SIBR complain of a greater number of defecations, a lower body mass index, the presence of a decrease in body weight within 1 month before the examination and more frequent complaints of bloating, flatulence, tearfulness and weakness. Thus, a hydrogen breath test can be used for differential diagnosis of exacerbation of IBD from clinical manifestations caused by SIBO.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>язвенный колит</kwd><kwd>болезнь Крона</kwd><kwd>синдром избыточного бактериального роста в тонкой кишке</kwd><kwd>водородный дыхательный тест</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inflammatory bowel diseases</kwd><kwd>ulcerative colitis</kwd><kwd>Crohn disease</kwd><kwd>small intestinal bacterial overgrowth</kwd><kwd>hydrogen respiratory test</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">Andrei M., Gologan S., Stoicescu A., Ionescu M., Nicolaie T., Diculescu M.
