Non-alcoholic fatty liver disease (NAFLD) went beyond the competence of a gastroenterologist and acquired the character of a multidisciplinary problem. NAFLD requires the attention of many professionals. A characteristic feature of NAFLD is the variety of concomitant diseases and pathological conditions with common pathophysiological mechanisms. This review summarizes and presents the data available in the modern literature on the association of NAFLD with cardiovascular diseases, type 2 diabetes mellitus, hypothyroidism, polycystic ovary syndrome, chronic kidney disease, colorectal cancer, obstructive sleep apnea, osteoporosis, psoriasis.

Patient management in chronic atrophic gastritis (CAG) in real clinical practice is a difficult task for a clinician. It is mainly due to the lack of reliable clinical stigmas that allow suspecting the presence of gastric mucosal atrophy. The diagnosis of chronic atrophic gastritis is valid only after a morphological assessment of gastrobiopaths taken during an endoscopy. According to a contemporary view, regardless of the inflammatory process etiology, CAG can progress to stomach cancer. At the same time, the point of no-return (at which the risk of inflammatory changes progression in the gastric mucosa and carcinogenesis preserves) is the CAG formation with the presence of intestinal metaplasia, even after the etiological factor is eliminated. Patients of this group, depending on the severity of inflammatory changes and atrophy, require constant dynamic follow-up and timely implementation of necessary measures for cancer prevention. To inhibit the progression of gastric mucosal precancerous changes, it is necessary to include the regimen using gastroprotective drugs for patients with CAG. Patients with autoimmune gastritis (in addition to the gastroprotective drugs) need to conduct regimens of cyanocobalamin therapy to prevent hematological and neurological disease manifestations.

Aim. To study the association of blood pressure (BP) and hypertension (HTN) with salt intake estimated by the survey and the urinary Na+ concentration among men and women 25-64 years old, examined within the ESSE-RF and ESSE-RF-2 studies.Material and methods. Representative samples of the Russian population aged 25-64 years were examined. At the first phase in 2012-2014, 21,888 people (men — 38,2%) were included, and at the second phase in 2017 — 6,714 people (men — 44,7%). The response rate was 80%. We used standard questionnaire. Adding more salt and the consumption of salted foods (sausages, deli meats, and pickled foods) in the criteria “daily or almost daily” was considered excess salt intake (ESI). BP measurement was carried out in a sitting position on the right hand. BP was measured twice with an interval of about 2-3 minutes. HTN was diagnosed at a systolic BP (SBP) ≥140 mm Hg and/or diastolic BP ≥90 mm Hg, or in case of antihypertensive therapy. In ESSE-RF-2, an analysis of the morning urine was additionally performed. Na+ was determined using the EX-Ds ion-selective electrolyte analyzer. All participants were stratified by the quintiles of urine sodium level. Data analysis was performed using the software package R 3.6.1. The models of linear and logistic regression were used. The differences were considered at p<0,05.Results. The average level of SBP significantly increases with an increase in Na+ in urine: 1,04 (0,60-1,48) mm Hg for the quintile of sodium distribution (p<0,001), the odds of HTN increases by 1,11 (1,05-1,17) times for the quintile (p<0,001). Questionnaire components of ESI are also significantly related to urinary Na+ levels. The consumption of sausages and deli meats has the greatest effect, causing an increase in the average Na+ level by 11,59 (7,06-16,12) mmol/l (p<0,001). The applied point scale is significantly related to urine sodium level and predicts HTN no worse than Na+ in the urine (p=0,15 for the difference hypothesis). One point on the scale increases the Na+ level by an average of 7,51 (5,01-10,02) mmol/l, SBP by an average of 0,74 (0,41-1,07) mm Hg and the odds of HTN by 1,1 (1,06-1,15) times (p<0,001 for all).Conclusion. In the pattern of ESI components, processed meat and sausage products take first place in terms of association strength with urine sodium. The questionnaire used to assess the proportion of people with ESI can be recommended for assessing this risk factor during screening. ESI detected by the questionnaire is associated with elevated BP and urinary Na+ values.

Aim. To review available data on the role of the microbiome and intestinal mucosal barrier in the development and progression of non-alcoholic fatty liver disease (NAFLD).Key points. The role of the human microbiome in the development and progression of NAFLD is associated with its effects on the risk factors (obesity, insulin resistance, type 2 diabetes), permeability of the intestinal barrier and absorption of such substances as short-chain fatty acids, bile acids, choline and endogenous ethanol. Liver fibrosis constitutes the leading factor determining the prognosis of patients in NAFLD, including cases associated with cardiovascular complications. Changes in the microbiome composition were demonstrated for various degrees of fibrosis in NAFLD.Conclusion. The results of modern studies confirm the formation of a new concept in the pathophysiology of NAFLD, which encourages the development of new therapeutic strategies.

Study goal: Identify clinically significant stigmas of reduced esophageal mucosal resistance.Materials and methods: The study included 181 patients aged 18–70 years with gastroesophageal refl ux disease (GERD).Complaints, age, sex, history of the disease, life history, physical examination data, results of laboratory and instrumental examinations, data on medication intake at the time of enrollment of the patient for the main disease and concomitant pathology were noted in the individual registration card (IRC).Results: The study demonstrated the presence of features suggesting with a higher degree of probability a reduced esophageal mucosal resistance in a certain group of patients with GERD. Individuals with early- onset GERD, males, young adults, smokers, and individuals with a high body mass index (BMI) have a higher risk of esophageal mucosal erosions. The presence of esophageal hernia of the diaphragm (EVD), intake of acetylsalicylic acid (ASA), calcium channel blockers (CCBs), or nonsteroidal anti-inflammatory drugs (NSAIDs) are factors that reduce esophageal mucosal resistance. The formation of erosive esophagitis is not associated with the subjective perception of GERD symptoms and does not affect the patient’s complaints.Conclusion: Clinical manifestations of GERD are not associated with the degree of esophageal mucosal damage and cannot be a phenotypic sign of erosive esophagitis requiring mandatory prescription of an esophagoprotector. Clinically significant stigmas of decreased esophageal mucosal resistance were revealed. The need in research of expediency and efficacy of prescription of esophagoprotector in patients with GERD, having GVHD or regularly taking BCA, ASA and other NSAIDs, including obligatory estimation of therapy effi cacy taking into account patient gender and age, has been established.
