From this standpoint, of particular interest is the study of the role of a number of major endocrine cells (EC) of the colon, secreting motilin, vasoactive intestinal polypeptide, and somatostatin, in IBS. <bold>Aims</bold> — to evaluate the density of ECs with different hormonal activities that secrete motilin, vasoactive intestinal polypeptide and somatostatin in the mucosa of the sigmoid colon in patients with IBS that occurs with constipation and diarrhea. <bold>Materials and methods.</bold> 85 patients with IBS were examined. The first group included 44 patients with diarrhea (IBSd), the second group included 41 patients with constipation (IBSc). The comparison group consisted of 36 practically healthy people. The diagnosis of IBS was based on the Rome IV criteria. Patients and healthy people were examined according to a single program, including clinical, instrumental (colonoscopy, ultrasound examination of the abdominal organs), laboratory (clinical blood test, feces for calprotectin and antibodies to gliadin in the presence of diarrhea), morphological and immunohistochemical methods. <bold>Results.</bold> The clinical picture of IBS corresponded to the classical manifestations of this pathology. Among patients with IBSc, there was a more frequent feeling of incomplete emptying of the intestine after defecation, compared with patients with IBSd (p &lt; 0.05). Among patients with IBSd, there was a statistically significant increase in the number of ECs producing motilin and vasoactive intestinal polypeptide, as well as a lower density of ECs secreting somatostatin, compared with the control group (p &lt; 0.05). In the IBSc group, there was a decrease in the number of ECs producing motilin, vasoactive intestinal polypeptide and an increase in the number of ECs producing somatostatin, compared with the control group (p &lt; 0.05). <bold>Conclusions.</bold> An increase in the number of cells producing motilin, vasoactive intestinal polypeptide and a decrease in the number of cells observed for the production of somatostatin in the mucosa of the sigmoid colon is characteristic of the manifestation of IBSd. At the same time, an increase in ECs secreting motilin, vasoactive intestinal polypeptide and an increase in cellular elements producing somatostatin reveals manifestations of IBSс.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Нарушения продукции нейроэндокринных пептидов в пищеварительном тракте могут вызывать изменения перистальтики кишечника и формирование висцеральной гиперчувствительности, характерной для больных с синдромом раздраженного кишечника (СРК). С этих позиций особый интерес представляет изучение роли ряда основных эндокринных клеток (ЭК) толстой кишки, секретирующих мотилин, вазоактивный кишечный полипептид и соматостатин, при СРК. <bold>Цель исследования</bold> — оценить плотность ЭК с разной гормональной активностью, секретирующих мотилин, вазоактивный кишечный полипептид и соматостатин, в слизистой оболочке сигмовидной кишки у пациентов с СРК, протекающим с запором и диареей. <bold>Материалы и методы. </bold>Обследовано 85 больных с СРК. В первую группу было включено 44 пациента с диареей (СРКд), во вторую — 41 больной с запором (СРКз). Группу сравнения составили 36 практически здоровых человек. Постановка диагноза СРК осуществлялась на основании Римских критериев IV. Больные и здоровые обследованы по единой программе, включающей клинические, инструментальные (колоноскопия, ультразвуковое исследование органов брюшной полости), лабораторные (клинический анализ крови, кал на кальпротектин и антитела к глиадину при наличии диареи), морфологические и иммуногистохимические методы. <bold>Результаты. </bold>Клиническая картина СРК соответствовала классическим проявлениям данной патологии. Среди пациентов с СРКз чаще встречалось чувство неполного опорожнения кишечника после дефекации по сравнению с больными с СРКд (p &lt; 0,05). Среди пациентов с СРКд было зафиксировано статистически значимое увеличение числа ЭК, продуцирующих мотилин и вазоактивный кишечный полипептид, а также более низкая плотность ЭК, секретирующих соматостатин, по сравнению с группой контроля (p &lt; 0,05). В группе с СРКз было отмечено уменьшение числа ЭК, продуцирующих мотилин, вазоактивный кишечный полипептид, и увеличение количества ЭК, продуцирующих соматостатин, по сравнению с группой контроля (p &lt; 0,05). <bold>Заключение.</bold> Увеличение плотности клеток, продуцирующих мотилин, вазоактивный кишечный полипептид, и снижение числа клеток, отвечающих за выработку соматостатина в слизистой оболочке сигмовидной кишки, характерны для клинических проявлений СРКд. В то же время снижение плотности ЭК, секретирующих мотилин, вазоактивный кишечный полипептид, и увеличение количества клеток, продуцирующих соматостатин, определяют клинические проявления СРКз.</p></trans-abstract><kwd-group xml:lang="en"><kwd>irritable bowel syndrome</kwd><kwd>motilin</kwd><kwd>vasoactive intestinal peptide</kwd><kwd>somatostatin</kwd><kwd>brain-gut axis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синдром раздраженного кишечника</kwd><kwd>мотилин</kwd><kwd>вазоактивный кишечный пептид</kwd><kwd>соматостатин</kwd><kwd>кишечно-мозговая ось</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Enck P, Aziz Q, Barbara G, et al.
