Human gut microbiota community structures in urban and rural populations in Russia

The microbial community of the human gut has a crucial role in sustaining host homeostasis. High-throughput DNA sequencing has delineated the structural and functional configurations of gut metagenomes in world populations. The microbiota of the Russian population is of particular interest to researchers, because Russia encompasses a uniquely wide range of environmental conditions and ethnogeographical cohorts. Here we conduct a shotgun metagenomic analysis of gut microbiota samples from 96 healthy Russian adult subjects, which reveals novel microbial community structures. The communities from several rural regions display similarities within each region and are dominated by the bacterial taxa associated with the healthy gut. Functional analysis shows that the metabolic pathways exhibiting differential abundance in the novel types are primarily associated with the trade-off between the Bacteroidetes and Firmicutes phyla. The specific signatures of the Russian gut microbiota are likely linked to the host diet, cultural habits and socioeconomic status. © 2013 Macmillan Publishers Limited. All rights reserved

European registry on the management of helicobacter pylori infection (HP-EUREG protocol): The first results of Russian centers

Aim: To assess the clinical practice of diagnosis and treatment in patients with Helicobacter pylori infection and to compare this practice with the international guidelines in the European Registry on the management of Helicobacter pylori infection, Hp-EuReg protocol), a multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group. Materials and methods: The data of 813 patients infected with H. pylori and entered in the Hp-EuReg register by the Russian centers in 2013-2015 were analyzed. Results: The most common methods for the primary diagnosis of H. pylori infection are histology (40.3%), rapid urease test (35.7%), and serology (17.2%). The duration of H. pylori eradication therapy was 7, 10, and 14 days in 18.0, 49.3, and 25.1%, respectively. To monitor the effectiveness of treatment, the investigators used a histological examination (34%), a urea breath test (27.3%), H. pylori stool antigen (22.8%), and a rapid urease test (16.3%). A serological test was carried out in 2.5% of the cases. No monitoring was done in 13.5% of the patients. The average eradication efficiency was 82.6%. If the therapy was ineffective, 80% of physicians did not intend to prescribe a new cycle of treatment. Conclusion: Significant differences were found between clinical practice and the current guidelines

Liver damage while Covid-19: problems of pathogenesis and treatment

The purpose of the review is to present an analysis of the current literature data on the pathogenesis and therapy of liver damage in Covid-19. Liver damage in COVID-19 patients can be caused by the direct cytopathogenic effect of SARS-CoV-2, an uncontrolled immune response, sepsis, severe hypoxia, or drug damage. In addition, COVID-19 can exacerbate and decompensate previously formed chronic liver diseases with the development of acute liver failure. Physicians should carefully assess the initial state of the liver, and after prescribing therapy, intensify monitoring of its functional state, especially in patients with severe COVID-19. In each clinical case, the doctor needs to establish the possible mechanisms of organ damage in order to select the most optimal patient management tactics, which would take into account all aspects of the COVID-19 course and liver damage. Currently, additional scientific information is required to uncover the features of liver damage during SARS-CoV-2 infection and in the postcovid period. Patients who have undergone COVID-19 need further monitoring to assess the long-term effects of the disease

Gastroesophageal reflux disease: features in patients with metabolic syndrome

The article is a literature review of the major etiopathogenetic mechanisms of the development and recent approaches to the treatment of gastroesophageal reflux disease in patients with metabolic syndrome. Recent data on the role of insulin resistance, impaired neurohumoral regulation of the upper gastrointestinal tract in patients with gastroesophageal reflux disease and metabolic syndrome is presented
