В исследование было включено 27 случаев АИГ и 9 случаев хронических атрофических гастритов не связанных с аутоиммунными механизмами развития болезни. Возраст больных варьировал от 36 до 77 лет и в среднем составил 54,9 года. Биоптаты забирали согласно принятым протоколам: из антрального отдела по 2–3 биоптата и по 2 биоптата из тела желудка. Проводили иммуногистохимическую реакцию с антителом к хромогранину А на автоматическом иммуностейнере Bond Max (Leica, Германия). Препараты были оцифрованы на сканере Aperio AT2 (Leica, Германия), для морфометрического анализа цифровых изображений и проведения подсчета использовали программу для просмотра и анализа цифровых изображений микропрепаратов QuPath v.0.3.0. Результаты обрабатывались в программе Jamovi, Version 1.6 (https://www.jamovi.org).</p></sec><sec><title>Результаты</title><p>Результаты. По результатам подсчета в группе больных с АИГ было отмечено повышение содержания НЭК. Выявлены диапазоны гиперплазии нейроэндокринных клеток: для АИГ диапазон составил 648–1736 клеток на 1 мм2, для других форм гастритов – 416–605 клеток на 1 мм2. В группе препаратов АИГ медиана составляет 925 клеток на 1 мм2, 1-й квартиль – 877 клеток на 1 мм2, 3-й квартиль – 1172 клетки на 1 мм2, межквартильный интервал – 295 клеток на 1 мм2 (асимметричное распределение); в группе с другими формами гастрита среднее арифметическое – 522±23 клеток на 1 мм2 (нормальное распределение).</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты позволили подтвердить гиперплазию НЭК у больных АИГ. Выявлена статистически значимая разница в количестве НЭК в теле желудка в группе АИГ и других гастритов (p≤0,01), что может быть предложено в виде дополнительного морфологического критерия диагностики АИГ.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to evaluate the content of neuroendocrine cells in immunohistochemically stained preparations and determine differences in the number of neuroendocrine cells (NEC) in the body of the stomach in autoimmune gastritis (AIG) and other forms of gastritis.</p><sec><title>Material and methods</title><p>Material and methods. The study included 27 cases of AIG and 9 cases of chronic atrophic gastritis not associated with autoimmune mechanisms of disease. The age of the patients ranged from 36 to 77 years and averaged 54.9 years. Biopsies were taken according to accepted protocols: 2–3 biopsies from the antrum and 2 biopsies from the body of the stomach. An immunohistochemical reaction was carried out with an antibody to chromogranin A on an automatic Bond Max immunostainer (Leica, Germany). The slides were digitized on an Aperio AT2 scanner (Leica, Germany), and QuPath v.0.3.0 software for viewing and analyzing digital images of slides was used for morphometric analysis of digital images and counting. The results were processed in the Jamovi program, Version 1.6 (https://www.jamovi.org).</p></sec><sec><title>Results</title><p>Results. According to the results of counting in the group of patients with AIG, there was an increase in the quantity of NEC. Ranges of hyperplasia of neuroendocrine cells were revealed: 648–1736 cells per 1 mm2 square were detected for AIG, 416–605 cells per 1 mm2 for other forms of gastritis. In the AIG group median is 925 cells per 1 mm2, the 1st quartil is 877 cells per 1 mm2, 3rd quartil is 1172 cells per 1 mm2, interquartile range is 295 cells per 1 mm2 (asymmetrical distribution). In the group with other forms of gastritis arithmetic mean is 522±23 cells per millimeter square (normal distribution).</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained results allowed to confirm NEC hyperplasia in patients with AIG. A statistically significant difference was found in the number of NEC in the body of the stomach in the group of AIG and other gastritis (p≤0,01), which can be proposed as an additional morphological criteria for diagnosing AIG.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аутоиммунный гастрит</kwd><kwd>нейроэндокринные клетки</kwd><kwd>гиперплазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autoimmune gastritis</kwd><kwd>neuroendocrine cells</kwd><kwd>hyperplasia</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">Белковец А.
