Гастрит — воспалительное заболевание слизистой оболочки желудка. Различают острый и хронический гастриты. Хронический гастрит — группа хронических заболеваний, которые морфологически характеризуются персистирующим воспалительным инфильтратом и нарушением клеточного обновления с развитием кишечной метаплазии, атрофии и эпителиальной дисплазии в слизистой оболочке желудка. С целью подтверждения диагноза гастрита и дуоденита, диагностики предраковых состояний и/или изменений слизистой оболочки желудка рекомендуется проведение эзофагогастродуоденоскопии (ЭГДС), при возможности ЭГДС высокого разрешения и виртуальной хромоэндоскопии с увеличением или без него, в том числе для выполнения прицельной биопсии с целью оценки стадии атрофии и кишечной метаплазии и выявления неоплазии. Всем пациентам с хроническим гастритом с положительными результатами тестирования на H. рylori в качестве этиологического лечения, а также с целью профилактики рака желудка рекомендуется проведение эрадикационной терапии. Пациентам с хроническим гастритом и симптомами диспепсии (боль и жжение в эпигастрии, переполнение в эпигастрии, чувство раннего насыщения), в том числе в сочетании с функциональной диспепсией, в качестве симптоматического лечения могут быть рекомендованы ингибиторы протонной помпы, прокинетики, ребамипид, висмута трикалия дицитрат. Пациентам с кишечной метаплазией, ограниченной одной анатомической областью, в большинстве случаев не рекомендуется наблюдение, особенно если высококачественное эндоскопическое исследование с биопсией позволило исключить выраженные стадии атрофического гастрита. Однако при наличии у таких пациентов отягощенного по раку желудка семейного анамнеза, неполной кишечной метаплазии, персистенции инфекции H. pylori им рекомендуется эндоскопическое наблюдение с хромоэндоскопией и прицельной биопсией 1 раз в 3 года. Пациентам с выраженным атрофическим гастритом рекомендуется высококачественное эндоскопическое наблюдение каждые 3 года. Пациентам с выраженным атрофическим гастритом с отягощенным наследственным анамнезом по раку желудка рекомендуется эндоскопическое наблюдение 1 раз в 1–2 года.Заключение. В клинических рекомендациях представлены актуальные данные об этиологии и патогенезе гастрита и дуоденита, методах лабораторной и инструментальной диагностики, основных подходах к этиологической эрадикационной терапии H. pylori и лечению симптомов диспепсии.</p></abstract><trans-abstract xml:lang="en"><p>Aim. The clinical guidelines are intended to supplement specialty decision-making for improved aid quality in patients with gastritis and duodenitis though acknowledging the latest clinical evidence and principles of evidencebased medicine.Key points. Gastritis is an inflammatory disease of stomach mucosa, with a separate definition of acute and chronic gastritis. Chronic gastritis is a cohort of chronic diseases uniting a typical morphology of persistent inflammatory infiltration, impaired cellular renewal with emergent intestinal metaplasia, atrophy and epithelial dysplasia of gastric mucosa. Oesophagogastroduodenoscopy (OGDS) or high-resolution OGDS with magnified or non-magnified virtual chromoendoscopy, including targeted biopsy for atrophy and intestinal metaplasia grading and neoplasia detection, are recommended to verify gastritis and duodenitis, precancer states and/or gastric mucosal changes. All chronic gastritis patients positive for H. рylori should undergo eradication therapy as aetiological and subsidiary for gastric cancer prevention. Chronic gastritis patients with symptoms of dyspepsia (epigastric pain, burning and congestion, early satiety), also combined with functional dyspepsia, are recommended proton pump inhibitors, prokinetics, rebamipide and bismuth tripotassium dicitrate in symptomatic treatment. With focal restricted intestinal metaplasia, follow-up is not required in most cases, mainly when advanced atrophic gastritis is ruled out in high-quality endoscopy with biopsy. However, a familial history of gastric cancer, incomplete intestinal metaplasia and persistent H. pylori infection render endoscopy monitoring with chromoendoscopy and targeted biopsy desirable once in three years. Patients with advanced atrophic gastritis should have high-quality endoscopy every 3 years, and once in 1–2 years if complicated with a familial history of gastric cancer.Conclusion. The recommendations condense current knowledge on the aetiology and pathogenesis of gastritis and duodenitis, as well as laboratory and instrumental diagnostic techniques, main approaches to aetiological H. pylori eradication and treatment of dyspeptic states.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гастрит</kwd><kwd>дуоденит</kwd><kwd>Helicobacter pylori</kwd><kwd>диспепсия</kwd><kwd>атрофия</kwd><kwd>метаплазия</kwd><kwd>дисплазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastritis</kwd><kwd>duodenitis</kwd><kwd>Helicobacter pylori</kwd><kwd>dyspepsia</kwd><kwd>atrophy</kwd><kwd>metaplasia</kwd><kwd>dysplasia</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">Marshall B.J., Warren J.R.
