Актуальная обобщающая система взглядов на данное заболевание представлена в консенсусе RE.GA.IN. (2024). Нами были выделены и структурированы наиболее прикладные положения консенсуса в контексте классификации и характеристики основных форм хронического гастрита, акцентированы подходы к диагностике и динамическому наблюдению, проиллюстрированы опорные эндоскопические критерии заболевания. Особое внимание уделено описанию эндоскопической картины нормы и патологии при использовании современных эндоскопических технологий, как интегральному фактору междисциплинарного взаимодействия клиницистов и диагностов. В своей работе мы постарались отдельно и развернуто затронуть проблему аутоиммунного подтипа заболевания как одной из наиболее клинически значимых в настоящий момент, но в то же время часто недооцененных форм хронического гастрита.</p></abstract><trans-abstract xml:lang="en"><p>Chronic gastritis holds one of the leading roles in the structure of pathology of the upper gastrointestinal tract, with which practicing specialists of related specialties - gastroenterologists, therapists, endoscopists - meet on everyday basis. The up-to-date generalizing system of views on this pathology is presented in the RE.GA.IN. consensus (2024). We have highlighted and structured the most practical points of the consensus in the context of classification and characterization of the main forms of chronic gastritis, emphasized approaches to diagnosis and dynamic observation, illustrated the supporting endoscopic criteria of the disease. Moreover, we paid special attention to the description of endoscopic patterns of normal and pathological findings using modern endoscopic technologies as an integral factor of interdisciplinary interaction between clinicians and diagnosticians. In our work we tried to specifically and thoroughly address the problem of autoimmune subtype of the condition as one of the most clinically significant at the current moment, but at the same time often underestimated forms of chronic gastritis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гастрит</kwd><kwd>Helicobacter pylori</kwd><kwd>предраковые состояния желудка</kwd><kwd>атрофия слизистой оболочки желудка</kwd><kwd>аутоиммунный гастрит</kwd><kwd>эзофагогастродуоденоскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chronic gastritis</kwd><kwd>Helicobacter pylori</kwd><kwd>preneoplastic conditions of the stomach</kwd><kwd>Gastric atropy</kwd><kwd>Autoimmune gastritis</kwd><kwd>gastroscopy</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">Rugge M., Genta R.M., Malfertheiner P; RE.GA.IN; RE GA IN.
