Материал и методы. Обследовано 495 больных СРК (III Римские критерии). Всем пациентам провели колоноилеоскопию с биопсией из ТОПК, водородный дыхательный тест с нагрузкой лактулозой, исследовали ФК. Результаты. У 57% больных СРК уровень ФК оказался достоверно выше, чем у здоровых лиц, причем у 37% - более 100 мкг/г. У больных СРК с повышенным уровнем ФК частота СИБР была достоверно выше, чем у больных СРК с нормальным уровнем ФК (77,1% и 64,8%, р=0,011). Установлена достоверная прямая корреляция между наличием СИБР и уровнем ФК у больных СРК (rs=0,153, p=0,001). Уровень ФК &gt;100 мкг/г явился достоверным предиктором воспаления СО ТОПК у больных СРК (ОШ 6,19, 95% ДИ 3,99-9,61, р&lt;0,0001). Установлена достоверная корреляция между уровнем ФК и активностью неспецифического терминального илеита (rs=0,399, p&lt;0,0001). Заключение. У больных СРК в сочетании с СИБР достоверно чаще наблюдается развитие воспалительных изменений в ТОПК, чем у больных СРК без СИБР (ОШ 2,69, 95% ДИ 1,79-4,04, р&lt;0,0001). Повышенный уровень ФК (&gt;100 мкг/г) является статистически значимым предиктором воспаления СО ТОПК у больных СРК (ОШ 6,19, 95% ДИ 3,99-9,61, р&lt;0,0001).</p></abstract><trans-abstract xml:lang="en"><p>Aim. We aimed to determine possible interrelation between fecal calprotectin (FC) level, that small intestinal bacterial overgrowth (SIBO) and ileum mucosal inflammation in patients with irritable bowel syndrome (IBS). Methods. Based on Rome III criteria, 495 IBS patients (376 female, mean age 36,6±0,4 years) were included. All patients underwent FC levels, ileocolonoscopy with biopsies of the terminal ileum and H2 lactulose breath test to evaluate the presence of SIBO. Results. Among the 495 IBS patients 57% had reproducibly elevated calprotectin, including 17% with levels higher than 100 µg/g. SIBO was more frequent among IBS patients with elevated FC levels (&gt;100 μg/g) than in those with normal FC levels (0-50μg/g) (77,1% vs 64,8%, р=0,011). We found a correlation between abnormal levels of FC and the presence of SIBO (Spearman r=0,153, p=0,001). Faecal calprotectin greater than 100 µg/g was predictive of ileum mucosal inflammation in IBS patients (OR6,19, 95%CI 3,99-9,61, р&lt;0,0001). The abnormal calprotectin level was correlated with the grade ileum mucosal inflammation (Spearman r=0,399, p&lt;0,0001). Conclusion. In IBS patients with SIBO the low-grade ileum mucosal inflammation was more frequent than in patients with IBS without SIBO (OR2.69, 95% CI 1.79-4.04, p &lt;0.0001). Elevated FC levels (&gt;100μg/g) were associated with low-grade ileum mucosal inflammation in IBS patients (OR6,19, 95%CI 3,99-9,61, р&lt;0,0001).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром раздраженного кишечника</kwd><kwd>синдром избыточного бактериального роста</kwd><kwd>фекальный кальпротектин</kwd><kwd>воспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>irritable bowel syndrome</kwd><kwd>fecal calprotectin</kwd><kwd>small intestinal bacterial overgrowth</kwd><kwd>ileum mucosal inflammation</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">Schmulson M., Bielsa M.
