Aim of publication. To present indications for antihelicobacter therapy, methods and sequence of diagnostics and eradication treatment of Helicobacter pylori (H. pylori) infection to general practitioners. Key points. Chronic gastritis caused by H. pylori infection, including that in «asymptomatic» patients can be considered to be an indication for H. pylori eradication therapy both as etiological treatment and opportunistic screening diagnostics for gastric cancer prevention. Indications for obligatory antihelicobacter therapy include stomach and a duodenum peptic ulcer (PU), stomach MALT-lymphoma, early gastric cancer with endoscopic resection. Breath test with 13 С-labeled urea, laboratory test for assessment of anti-H. pylori antibodies in feces, rapid urease test and serological method can be recommended for primary diagnostics of infection. Serological test is not applicable after antihelicobacter therapy. According to the bulk of regional studies clarithromycin resistance level of H. pylori strains in Russia does not exceed 15%. Obtained data indicate the absence of high metronidazole-resistance of H. pylori as well as double resistance to clarithromycin and metronidazole. Standard triple therapy including proton pump inhibitor (PPI), clarithromycin and amoxicillin is recommended Цель публикации. Ознакомить практикующих врачей с показаниями к проведению антигеликобактерной терапии, методами и порядком проведения диагностики и эрадикационной терапии инфекции Helicobacter pylori (H. pylori). Основные положения. Хронический гастрит, вызванный инфекцией Н. pylori, в том числе у «бессимптомных» лиц, можно рассматривать как показание к проведению эрадикационной терапии инфекции Н. pylori в качестве этиотропного лечения и оппортунистического скрининга для профилактики рака желудка. Показаниями к обязательному проведению антигеликобактерной терапии служат язвенная болезнь желудка и двенадцатиперстной кишки, MALT-лимфома желудка, ранний рак желудка с эндоскопической резекцией. В качестве методов первичной диагностики инфекции H. pylori используют дыхательный тест с мочевиной, меченной 13 С, определение антигена H. pylori в кале лабораторным способом, быстрый уреазный тест и серологический метод. После проведения антигеликобактерной терапии серологический метод не применяют. Согласно результатам большинства региональных исследований, показатели устойчивости штаммов H. pylori к кларитромицину в России не выше

The National Consensus was prepared with the participation of the National Medical Association for the Study of the Multimorbidity, Russian Scientific Liver Society, Russian Association of Endocrinologists, Russian Association of Gerontologists and Geriatricians, National Society for Preventive Cardiology, Professional Foundation for the Promotion of Medicine Fund PROFMEDFORUM. The aim of the multidisciplinary consensus is a detailed analysis of the course of non-alcoholic fatty liver disease (NAFLD) and the main associated conditions. The definition of NAFLD is given, its prevalence is described, methods for diagnosing its components such as steatosis, inflammation and fibrosis are described. The association of NAFLD with a number of cardio-metabolic diseases (arterial hypertension, atherosclerosis, thrombotic complications, type 2 diabetes mellitus (T2DM), obesity, dyslipidemia, etc.), chronic kidney disease (CKD) and the risk of developing hepatocellular cancer (HCC) were analyzed. The review of non-drug methods of treatment of NAFLD and modern opportunities of pharmacotherapy are presented. The possibilities of new molecules in the treatment of NAFLD are considered: agonists of nuclear receptors, antagonists of pro-inflammatory molecules, etc. The positive properties and disadvantages of currently used drugs (vitamin E, thiazolidinediones, etc.) are described. Special attention is paid to the multi-target ursodeoxycholic acid (UDCA) molecule in the complex treatment of NAFLD as a multifactorial disease. Its anti-inflammatory, anti-oxidant and cytoprotective properties, the ability to reduce steatosis an independent risk factor for the development of cardiovascular pathology, reduce inflammation and hepatic fibrosis through the modulation of autophagy are considered. The ability of UDCA to influence glucose and lipid homeostasis and to have an anticarcinogenic effect has been demonstrated. The Consensus statement has advanced provisions for practitioners to optimize the diagnosis and treatment of NAFLD and related common pathogenetic links of cardio-metabolic diseases.

Aim. Current clinical recommendations accentuate current methods for the diagnosis and treatment of irritable bowel syndrome (IBS).Key points. IBS is a functional bowel disorder manifested with recurrent, at least weekly, abdominal pain with the following attributes (any two leastwise): link to defecation, its frequency or stool shape. The symptoms are expected to persist for at minimum three months in a total six-month follow-up. Similar to other functional gastrointestinal (GI) disorders, IBS can be diagnosed basing on the patient symptoms compliance with Rome IV criteria, provided the absence of potentially symptom-causative organic GI diseases. Due to challenging differential diagnosis, IBS can be appropriately established per exclusionem, with pre-examination as follows: general and biochemical blood tests; tissue transglutaminase IgA/IgG antibody tests; thyroid hormones test; faecal occult blood test; hydrogen glucose/ lactulose breath test for bacterial overgrowth; stool test for enteric bacterial pathogens and Clostridium difficile A/B toxins; stool calprotectin test; abdominal ultrasound; OGDS, with biopsy as appropriate; colonoscopy with biopsy. The IBS sequence is typically wavelike, with alternating remissions and exacerbations often triggered by psychoemotional stress. Treatment of IBS patients includes dietary and lifestyle adjustments, various-class drug agents prescription and psychotherapeutic measures.Conclusion. Adherence to clinical recommendations can facilitate timely diagnosis and improve medical aid quality in patients with different clinical IBS variants.
