Заболеваемость ротавирусной инфекцией в России также остаётся на стабильно высоком уровне, приводя к колоссальному социально-экономическому ущербу. Помимо этого, у детей, перенесших тяжелые формы заболевания, существует риск формирования постинфекционных функциональных расстройств желудочно-кишечного тракта, приводящих к снижению качества жизни детей на фоне длительного сохранения диспепсических явлений. Недостаточно изученными остаются патогенетические механизмы и факторы, предрасполагающие к формированию функциональных расстройств желудочно-кишечного тракта у реконвалесцентов ротавирусной инфекции.</p></sec><sec><title>Цель</title><p>Цель: установить возможную роль нарушений микробиоценоза кишечника и иммунного реагирования в формировании гастроэнтерологической патологии у детей – реконвалесцентов ротавирусной инфекции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: работа выполнена в 2014–2019 гг. в Детском научно-клиническом центре инфекционных болезней. В ходе выполнения работы проведено комплексное клинико-лабораторное обследование 60 детей в возрасте от 1 до 7 лет, перенесших ротавирусную инфекцию в тяжелой или среднетяжелой форме, с начала инфекционного заболевания с последующим трехлетним катамнестическим наблюдением. Особое внимание уделялось оценке микробиоценоза кишечника и иммунного реагирования у исследуемой группы пациентов. Интерпретация диспепсических симптомов в катамнестический период проводилась на основании Римских критериев IV пересмотра.</p></sec><sec><title>Результаты</title><p>Результаты: установлена структура расстройств желудочно-кишечного тракта после ротавирусной инфекции. Показано, что при ротавирусной инфекции отмечаются стойкие изменения микробиоты кишечника, характеризующиеся уменьшением количества симбиотических Bacteroides thetaiataomicron, Lactobacillus spp. и Faecalibacterium prausnitzii и избыточным ростом условно-патогенных микроорганизмов, в том числе Bacteroides fragilis.</p></sec><sec><title>Заключение</title><p>Заключение: выявлена тесная взаимосвязь ряда факторов (снижение уровня вирус-индуцированной продукции ИФНγ и сывороточного IgA, избыточный рост Proteus spp., Bacteroides fragilis и снижение уровня Faecalibacterium prausnitzii и Bacteroides thetaiotaomicron) с формированием в катамнестическом периоде функциональных расстройств желудочно-кишечного тракта. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Rotavirus infection (RVI) is one of the most common childhood illnesses in countries where routine vaccination against the disease isn`t introduced. The incidence of RVI in Russia remains at a consistently high level, leading to a huge socio-economic damage. In addition, in children who have undergone severe forms of the disease, have high risk of post-infectious functional disorders of the gastrointestinal tract (FD), leading to a decrease in the quality of life and prolonged persistence of dyspeptic phenomena. The pathogenetic mechanisms and factors predisposing to FD in RVI convalescents remain insufficiently studied.</p><p>The aim of the study was to establish the possible role of intestinal microbiocenosis disorders and immune response in the formation of gastroenterological pathology in children, convalescents of RVI.</p></sec><sec><title>Material and methods</title><p>Material and methods: The work was performed in 2014- 2019. in Pediatric Research and Clinical Center for Infectious Diseases. In the course of the implementation, a comprehensive clinical and laboratory examination was carried out for 60 children aged 1 to 7 years who had suffered RVI in a severe or moderate form, since the onset of infection followed by a three-year follow-up observation. Particular attention was paid to the assessment of intestinal microbiocenosis and immune response in the study group of patients. The interpretation of dyspeptic symptoms in the follow-up period was carried out on the basis of the Rome IV revision criteria. The structure of gastrointestinal tract disorders after rotavirus infection has been established.</p></sec><sec><title>Results</title><p>Results: It was shown that with RVI, persistent changes in the intestinal microbiota are observed, characterized by a decrease in the number of symbiotic Bacteroides thetaiataomicron, Lactobacillus spp. and Faecalibacterium prausnitzii and overgrowth of semipathogenius microorganisms, including Bacteroides fragilis.</p></sec><sec><title>Conclusion</title><p>Conclusion: A close relationship of a number of factors (a decrease in the level of virus-induced production of IFNγ and serum IgA, overgrowth of Proteus spp., Bacteroides fragilis and a decrease in the level of Faecalibacterium prausnitzii and Bacteroides thetaiotaomicron) with the formation of FD in the follow-up period was revealed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ротавирусная инфекция</kwd><kwd>дети</kwd><kwd>катамнез</kwd><kwd>функциональные расстройства желудочно-кишечного тракта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rotavirus infection</kwd><kwd>children</kwd><kwd>catamnesis</kwd><kwd>functional disorders of the gastrointestinal tract</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">Горелов, А.В.
