The microbiome of patients with irritable bowel syndrome: pathophysiology and applied aspects

Irritable bowel syndrome is a clinically and socially significant disease. The pathophysiology, the clinical manifestations of this disease and the  prognosis for  the patient are closely related to dysbiotic disorders of  the intestine. This review summarizes the ideas about changes in the intestinal microbiome in patients with irritable bowel syndrome. The pathogenetically substantiated approaches to the correction of dysbiosis that improving treatment outcomes are also considered. The results of the FLORAVIE clinical trial, which were discussed at the Expert Council “Identification of indications for prescribing probiotics in patients with irritable bowel syndrome” on March 18, 2022, are presented. Members of the Expert Council, Russian and international clinical guidelines emphasize the relevance of targeted probiotics administration. It was noticed that only strain specificity allows predicting a positive clinical response and has a certain evidence base. In this regard, the FLORAVIE study, conducted in real clinical practice in patients with predominantly severe forms of irritable bowel syndrome, is clinically relevant. It has been demonstrated that 30-day administration of the B. longum 35624 probiotic has reduced the severity of irritable bowel syndrome and has improved the quality of life in all subgroups of patients, especially in those with the most severe form of the disease. The data presented indicate that the inclusion of probiotic strains with proven mechanism of action in the complex therapy of irritable bowel syndrome can lead to the transformation of the course of the disease and improve the quality of life of patients. The high level of evidence made it possible to introduce the probiotic strain Bifidobacterium longum 35624 into a number of domestic and foreign guidelines

Features of Medical Care Providing to Patients with Digestive Diseases in the Krasnodar Region during the COVID-19 Pandemic

The aim of the study: optimization the medical care provision to patients with diseases of the digestive system (DD) in the Krasnodar Region during the COVID-19 pandemic.Material and methods. The analysis of the features of the DD course in the Krasnodar Region was carried out according to the data of form C 51 “Distribution of the dead by sex, age groups and causes of death” of the Territorial Federal State Statistics Service in the Krasnodar Region, as well as monitoring the quality of medical care for patients with DD for the period from 2019 to 2021 years.Results. During the COVID-19 pandemic, the routing of gastroenterological patients, dispensary observation and preventive measures have undergone some changes. In the structure of total mortality in the Krasnodar Region, mortality from DD was 21.6 % in 2020 and 4.0 % in 2021. The decrease in the growth of mortality rate, including from DD, in the second year of the pandemic is associated with the completed healthcare systems reformatting. The increase in hospital mortality in patients with gastric and duodenal ulcers, ulcerative colitis, and diverticular disease had a significant impact on mortality rates from DD. The decreasing number of hospitalizations was explained due to the conversion of a number of hospitals into hospitals for the treatment of patients with COVID-19. The hospitalization was mainly carried out for emergency indications and patients with a more severe course of the disease. The pandemic has increased the need for telemedicine: 378 tele-consultations on the gastroenterological profile was carried out in the Krasnodar Region in 2021.Conclusion. Healthcare system workload in the Krasnodar Region increased significantly during the coronavirus pandemic that required a number of structural adjustments. In recent times, the regional health care is returning to the planned mode of providing medical care

The effectiveness of minimally invasive surgical treatment of portal hypertension complications in 832 patients with liver cirrhosis treated at the Regional Clinical Hospital no. 2 of the Ministry of Health of the Krasnodar Region were also evaluated.Results: The mortality rate in patients with liver cirrhosis, admitted in first-level institutions of medical care due to acute bleeding from esophageal varices, reached 26.3%. In conditions of surgical treatment of complications of portal hypertension in a third-level institution of specialized care it did not exceed 4.7%.Conclusion: The optimal approach to the surgical treatment of patients with liver cirrhosis is to stop the bleeding from esophageal varices at the first stage of medical care and to treat portal hypertension complications using minimally invasive technologies in a multidisciplinary clinic involving a multidisciplinary team of doctors

Digestive Disease Mortality Dynamics During New Coronavirus Infection Pandemic in Different Subjects of Russian Federation

Aim. An analysis of digestive disease mortality dynamics in different subjects of the Russian Federation in course of the new coronavirus infection pandemic.Key points. In most subjects of the Russian Federation, the first half of 2021 enduring the COVID-19 pandemic has witnessed a higher overall mortality from digestive diseases and from peptic ulcer, liver and pancreatic illnesses compared to the same period in 2020. This situation may have roots in both the adverse impact of coronavirus infection on pre-existing digestive diseases and shortages in providing specialty medical aid to gastroenterological patients during the pandemic. Improved outpatient care and remote counselling, as well as successful educational measures, may reduce gastroenterological disease-associated mortality.Conclusion. Most regions of Russia have registered a growing mortality from digestive diseases at the new coronavirus infection pandemic due to the SARS-CoV-2 adverse impact on illness progression, as well as imposed difficulties in providing specialty medical aid

Clinical Guidelines of the Russian Gastroenterological Association on the Diagnostics and Treatment of Eosinophilic Esophagitis

Aim. This paper presents guidelines on the diagnostics and treatment of eosinophilic esophagitis, which can be used by practitioners in their everyday practice.Summary. Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease of the esophagus characterized by the symptoms of esophageal dysfunction and a pronounced eosinophilic infiltration of the esophageal mucosa. The EoE diagnostics is based on the clinical manifestations of the disease (dysphagia, food impaction, chest pain regardless of swallowing), as well as on the combination of endoscopic and histological signs. The diagnostic criterion is the eosinophilic infiltration of the esophageal mucosa with an eosinophil density of ≥ 15 per high power field (×400) in at least one of the biopsy specimens (about 60 eosinophils in 1 mm2). Total IgE levels, peripheral blood eosinophilia and skin allergy tests are considered to be additional diagnostic means. Several approaches are used for the treatment of EoE, including proton pump inhibitors (PPIs) and topical glucocorticosteroids (GCS), as well as elimination diets. The choice of therapy should be individualized, with the mandatory assessment of the treatment efficacy after 6–12 weeks using esophagogastroduodenoscopy with biopsy sampling. Endoscopic dilatation should be considered in patients suffering from severe dysphagia due to esophagus stricture.Conclusion. Increased incidence of EoE predominantly among children and young people, as well as its chronic character requiring long-term maintenance therapy, make EoE a significant issue to the practice of gastroenterology
