Aim. The practical guidelines are intended for primary care physicians, general practitioners, paediatricians, gastroenterologists and general internists to advance the treatment and prevention of gastroenterological diseases in adults and children in therapies with probiotics, prebiotics, synbiotics and their enriched functional foods.Key points. Probiotics are live microorganisms that sustain health of the host when supplied in adequate amounts. Prebiotics include human-indigestible but accessible to gut microbiota substances expediting specific changes in the composition and/or activity of gastrointestinal microbiota that favour the host health. The mechanism of probiotic action comprises the quorum resistance maintenance, nutrient substrate metabolism and end metabolite recycling, macroorganism-sustaining substrate production, as well as the mediation of local and adaptive immune responses.The Russian Federation regulates market differently for biologically active food additives (BAFA), medicinal products (drugs) and functional food products (FFP). We overview the probiotic strains regulated in Russia as BAFAs, drugs and FFPs and provide recommendations on the use of these strains in treatment and prevention of gastroenterological diseases in children and adults.Conclusion. The clinical efficacy of probiotics, prebiotics, synbiotics and fortified functional foods depends on the prebiotic and strain properties and is verified in appropriate comparative clinical trials. Not all probiotics registered in Russia as BAFAs, drugs and FFPs have a strain identity, which provides no warranty of the clinical effect expected. The FFP legislation demands improved regulation mechanisms and control for therapeutic efficacy.
Острая респираторная инфекция, вызванная новым коронавирусом (SARS-CoV-2) остается глобальной проблемой и в настоящее время. Наиболее распространенными начальными симптомами у пациентов с инфекцией, вызванной SARS-Cov-2, являются лихорадка, кашель, одышка. Похожие клинические проявления (прежде всего, лихорадка, кашель и одышка) могут быть и при других вирусных респираторных инфекциях, что затрудняет дифференциальную диагностику COVID-2019 с острыми респираторными инфекции другой этиологии. Кроме того, даже во время вспышек респираторных заболеваний, вызванных новым патогеном, распространенные респираторные вирусы продолжают циркулировать и потенциально способны вызывать сочетанное инфицирование. Всё это необходимо учитывать при поиске оптимальной терапевтической тактике.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
