Материалы и методы. В исследование было включено 60 пациентов с гастроэнтерологическими симптомами, перенесших новую коронавирусную инфекцию, получавших антибактериальные препараты не менее 7 дней для лечения осложнений COVID-19. Из них 30 человек составили группу «Лечение» и получали биологически активную добавку «Максифлор Максимум» в дозе 1 капсула в сутки курсом 4 недели. 30 человек наблюдались проспективно в группе «Контроль». Анализ субъективного статуса осуществляли с использованием русифицированного опросника Gastrointestinal Symptom Rating Scale (GSRS). Всем пациентам выполнен анализ кала на дисбактериоз. Анкетирование и микробиологический тест выполнялись в первый день исследования, а также повторно через 10 и 30 дней. Результаты и обсуждение. Выраженность гастроэнтерологических симптомов после 4 недель терапии «Максифлор Максимум» была статистически значимо ниже, чем в контрольной группе. Отмечалось значительное субъективное улучшение самочувствия - снижение частоты абдоминальной боли, интенсивности диспепсии, нормализовалась частота стула (p&lt;0,05). Зарегистрирована положительная динамика показателей кишечной микробиоты в группе «Лечение». Статистически значимо снизилось число условно-патогенных представителей микрофлоры и возрос пул полезных сапрофитов (p&lt;0,05). В группе «Контроль» отмечалось отсутствие статистически значимой динамики состояния кишечной микробиоты. Заключение. Динамика клиническо-лабораторных показателей, отражающих течение COVID-19, указывает на эффективность применения синбиотика «Максифлор Максимум» в качестве адъювантной терапии, и дает возможность рекомендовать его к использованию в комплексном лечении пациентов с новой коронавирусной инфекцией.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study: to evaluate the effect of the Maxiflor Maximum dietary supplement on the severity of dyspepsia and colon microbiota in patients who had a new coronavirus infection and were treated with antibacterial drugs. Materials and methods. The study included 60 patients with gastrointestinal symptoms who had a novel coronavirus infection and received antibacterial drugs for at least 7 days to treat complications of COVID-19. Of these, 30 people made up the “Treatment” group and received the biologically active supplement “Maxiflor Maximum” at a dose of 1 capsule per day for 4 weeks. 30 people were observed prospectively in the Control group. Analysis of subjective status was carried out using the Russified Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. All patients underwent fecal analysis for dysbacteriosis. The questionnaire and microbiological test were performed on the first day of the study, and again after 10 and 30 days. Discussion. The severity of gastroenterological symptoms after 4 weeks of “Maxiflor Maximum” therapy was statistically significantly lower than in the control group. There was a significant subjective improvement in well-being - a decrease in the frequency of abdominal pain, the intensity of dyspepsia, the frequency of stools normalized (p&lt;0.05). A positive dynamics of intestinal microbiota indicators was registered in the “Treatment” group. The number of opportunistic representatives of the microflora decreased statistically and the pool of beneficial saprophytes increased (p&lt;0.05). In the “Control” group, there was a lack of statistically significant changes in the state of the intestinal microbiota. Conclusion. The dynamics of clinical and laboratory parameters reflecting the course of COVID-19 indicates the effectiveness of using the Maxiflor Maximum synbiotic as an adjuvant therapy, and makes it possible to recommend it for use in the complex treatment of patients with a new coronavirus infection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дисбиоз</kwd><kwd>COVID-19</kwd><kwd>антибиотик-ассоциированная диарея</kwd><kwd>Максифлор Максимум</kwd><kwd>анализ кала на дисбактериоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dysbiosis</kwd><kwd>COVID-19</kwd><kwd>antibiotic-associated diarrhea</kwd><kwd>Maxiflor Maximum</kwd><kwd>fecal analysis for dysbacteriosis</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">Wang Y.
