[Inflammatory bowel diseases: Transformation of representations. A review].

The global burden of inflammatory bowel disease (IBD) is currently significant and continues to grow due to the increasing prevalence of ulcerative colitis (UC) and Crohn's disease (CD), the increasing costs of diagnosis and treatment, and the high level of disability in patients with this disease. Categories, which leads to the search for risk factors and predictors of aggressive course and extraintestinal manifestations. According to the latest data, the prevalence of UC in Russia is 16.6 per 100 000 population, the annual registered increase is 11.3%; the prevalence of CD is 5.6 per 100 000 population, and the increase is 13.7%. In the Russian population of patients with IBD, the average age of disease onset is 35.3 years for UC and 31.2 years for CD. Moreover, in 89.3% of patients with UC, it took at least 2 years to verify the diagnosis, and in CD, within 2 years from the onset of clinical symptoms, the diagnosis was established in only 72.6% of patients. One of the dominant characteristics of IBD is its multisystem nature, which leads to the development of extraintestinal manifestations (ECM), which can be observed in 50-60% of patients, while up to 25% of patients with IBD have several EMC and the most common variants are joint lesions. A higher frequency of extraintestinal manifestations is observed in CD (up to 45% of patients), in female patients, in smokers and with a longer duration of the disease. To predict clinical remission, the level of fecal calprotectin and CRP, the need for glucocorticosteroids are important, to predict endoscopic remission - the level of fecal calprotectin, and to predict histological remission, an endoscopic Schroeder index value of ≤1 is important. The absolute risk of developing colorectal cancer in IBD remains relatively low, ranging from 1.1 to 5.4% after 20 years of disease. The main risk factors for IBD are total intestinal damage, high inflammatory activity, the stricturing phenotype of CD and the presence of primary sclerosing cholangitis.

[Liver cirrosis and complication risk management].

Liver cirrhosis (LC) takes the main place in the structure of the pathology of the digestive system in terms of the frequency of mortality, as well as in the development of fatal and poorly controlled complications, which requires the search for effective methods for preventing the progression of the disease and the development of complications. The article provides updated information on the role of the intestinal microbiota, as well as endotoxemia and increased intestinal permeability syndromes in the pathophysiology of LC and its complications. The results of recent meta-analyses of the impact of dysbiotic disorders on the prognosis of the LC and the options for their correction are presented. Understanding of the significance of involvement of gut microbiota in the pathogenesis of LC has become one of the levers of management of the risks of complications of LC. In this case, the livergut axis can be considered to be the leading link to the formation of most of the main complications of LC.

[Pharmacotherapy of inflammatory bowel diseases: efficacy performance and safety management].

Treatment of inflammatory bowel diseases IBD (Crohns disease, ulcerative colitis) is aimed at achieving clinical, endoscopic and histological remission, minimizing surgical complications, and ensuring a normal quality of life. However, the use of medical treatment is potentially associated with various adverse events, among which infectious complications, malignant neoplasms, as well as myelotoxicity, hepatotoxicity, skin lesions and others. The risk of side effects depends on the type of drug therapy (5-aminosalicylates, thiopurines, biologicals, etc.), the duration of treatment, the presence of extra-intestinal manifestations, etc. The article provides an overview of data on both the effectiveness and frequency of various side effects of the main classes of drugs in IBD, presents methods of investigation which can predict the effectiveness and development of side effects, the implementation of which can be considered as a variant of personalized therapy in IBD.

Important problems in the diagnosis and treatment of primary sclerosing cholangitis (based on the Russian consensus on diagnosis and treatment autoimmune hepatitis. Moscow, 2018).

The article is published based on the results of the Russian Consensus on the diagnosis and treatment of primary sclerosing cholangitis (PSC), discussed at the 44th annual Scientific Session of the CNIIG "Personalized Medicine in the Era of Standards" (March 1, 2018). The aim of the review is to highlight the current issues of classification of diagnosis and treatment of patients with PSC, which causes the greatest interest of specialists. The urgency of the problem is determined by the multivariate nature of the clinical manifestations, by often asymptomatic flow, severe prognosis, complexity of diagnosis and insufficient study of PSC, the natural course of which in some cases can be considered as a function with many variables in terms of the nature and speed of progression with numerous possible clinical outcomes. In addition to progression to portal hypertension, cirrhosis and its complications, PSC can be accompanied by clinical manifestations of obstructive jaundice, bacterial cholangitis, cholangiocarcinoma and colorectal cancer. Magnetic resonance cholangiography is the main method of radial diagnostics of PSC, which allows to obtain an image of bile ducts in an un-invasive way. The use of liver biopsy is best justified when there is a suspicion of small-diameter PSC, autoimmune cross-syndrome PSC-AIG, IgG4-sclerosing cholangitis. Currently, a drug registered to treat primary sclerosing cholangitis which can significantly change the course and prognosis of the disease does not exist. There is no unified view on the effectiveness and usefulness of ursodeoxycholic acid and its dosage in PSC. Early diagnosis and determination of the phenotype of PSC is of clinical importance. It allows to determine the tactics of treatment, detection and prevention of complications.

[Characteristics of the gastrointestinal myoelectrical activity in patients with nonalcoholic fatty liver disease associated with metabolic syndrome].

PURPOSE: Electrogastroenterography (EGEG) is a method of measuring action potentials of the digestive tract. The aim of the study was to evaluate the main features of the gastrointestinal myoelectrical activity (GI MEA) in patients with nonalcoholic fatty liver disease (NAFLD) associated with metabolic syndrome (MS). MATERIALS AND METHODS: GI motility function in fasting and postprandial periods by the peripheral EGEG (EGEG system "Gastroenterological GEM-01") were recorded in 33 patients with NAFLD associated with MS, 26 patients with mixed type of Irritable Bowel Syndrome (IBS) and 10 healthy volunteers aged from 18 to 70 years. RESULTS: Total fasting GI MEA data of patients with NAFLD associated with MS (Me = 40,99 MB) dominated over the same in patients with IBS (Me = 23.84 mV) and healthy volunteers (Me = 11.26 mV), the differences between EGEG parameters was not significant but critical (H = 5.997, p = 0.050). This trend was observed in postprandial period (H = 0.891, p = 0.640). In postprandial period total GI MEA in patients with NAFLD associated with MS was increased in 36.4% patients (95% CI: 24.7-56.3%) only while in IBS patients and healthy volunteers total GI MEA tract were increased in 76.9% patients (95% CI: 58.0-89.0%) and in 90.0% (95% CI: 59.6-98.2%) correspondently (χ2 = 14.12, p = 0.001). Postprandial ratio (PPR) (ratio between total GI MEA in postprandial and fasting periods) of GI MEA were less than 1.0 in patients with NAFLD associated with MS (Me = 0.65) and less then PPRs in patients with IBS and healthy volunteers (H = 10.378, p = 0.006). PPR in patients with IBS was less then this ratio in healthy volunteers (Me = 1.48 vs Me = 1.66) CONCLUSION: The increased total GI MEA is observed in patients with NAFLD associated with MS. Patients with NAFLD associated with MS have abnormal GI MEA in response on food stimulation. This fact may be important in the development of NAFLD and MS.

[On the possibilities of correction of changes of the gastrointestinal tract microbiota in patients with lung cancer treated receiving chemotherapy].

UNLABELLED: The aim of the study was the improvement of technologies of treatment of patients with the lung cancer receiving chemotherapy on the basis of using with the complex therapy of the combined probiotic based on the Bacillus subtilis strain. MATERIALS AND METHODS: 30 patients with the lung cancer receiving the first and second line of the first cycle of chemotherapy were included. The age of patients varied from 49 to 73 years, the average duration of the disease was 1 year. Patients of the main group (n = 21) received the combined probiotic based on the Bacillus subtilis strain together with the chemotherapy course. Patients of control group (n = 9) received only chemotherapeutic preparations. All patients were observed before and after treatment: the standardized inquiry for detection of intestinal complaints, microbiological research of feces (definition of qualitative and quantitative characteristics of gut microbiota), the research of metabolites of intestinal microorganisms in blood by the method of the gas-liquid chromatography - mass-spectrometry by G. A. Osipov's method. The efficiency of probiotic therapy was evaluated by results of studied indicators dynamics. RESULTS: Main symptoms of the intestinal dyspepsia were observed in patients with the lung cancer receiving chemotherapy such as constipation and intestinal microflora violations (decreased quantity of Lactobacillus, Bifidobacterium, Bacteroides and increased quantity of different pathogenic microorganisms). It was noted decreased rate of intestinal dyspepsia symptoms and improvement of intestinal microflora composition after the treatment course by the combined probiotic based on the Bacillus subtilis strain. CONCLUSION: Using of probiotic medicines with the chemotherapy in lung cancer patients is promising to reduce the frequency of gastrointestinal complaints and prevent deterioration of the gut microflora.

[Efficiency of ursodeoxycholic acid therapy in non-alcoholic fatty liver disease associated with metabolic syndrome].

INTRODUCTION: Nonalcoholic Fatty Liver Disease (NAFLD) is one of the most common liver disease. Its prevalence is 20-30% in the population of developed countries, its prevalence is 26% in Russia. NAFLD is observed in many patients with Metabolic Syndrome. Because of the wide prevalence of this disease it is required to find best drugs influencing mechanisms of its development, chronicity and progression. MATERIALS AND METHODS: 36 patients were included to the study. Mean age of patients was 43 +/- 3.9 years. Patients of the main group received the ursodeoxycholic acid within 2 months. Patients of the control group received the plant origin hepatoprotective medicine. All patients before and after treatment were carried out the biochemical analysis of blood, the liver ultrasound examination, the bioimpedance body composition analysis, the microbiological examination of faeces, the examination of metabolites of microorganisms in the blood by the method of gas-liquid chromatography - mass spectrometry, developed by Osipov G. A. RESULTS: The reduction of hepatic transaminases, the trend to normalization of the lipid profile, the reduction of body weight, the reduction of amount of adipose tissue in the body, the increase of Bifidobacterium spp., Lactobacillus spp., Enterococcus spp., the increase of levels of Bifidobacterium spp., Lactobacillus spp. Metabolites, the decrease of endotoxin plasma level and the decrease of total microbial load were observed after the UDCA treatment. The results of the study showed the prospectivity of the using of UDCA for NAFLD associated with Metabolic Syndrome.
