Aim. The aim of this literature review is to generalize existing approaches to the pathogenetic treatment of gastritis as a basis for the prevention of gastric cancer, as well as to submit a resolution of a scientific symposium that brought together gastroenterologists from a number of CIS countries.Background.  H. pylori infection is widespread in CIS countries. The proportion of infected adults in the population ranges from 60 % to over 90 %. This causes a high incidence of chronic gastritis and other diseases associated with H. pylori. In 2012, gastric cancer was recognized as the 3rd leading malignant disease in the Kyrgyz Republic and the Republic of Uzbekistan, 5th — in Belarus and Kazakhstan, 6th — in Armenia and the Russian Federation. According to the standardized cancer mortality rate, gastric cancer takes the 1st place in Kyrgyzstan and Uzbekistan, 2nd — in Belarus, 3rd — in Kazakhstan, and 4th — in Armenia and Russia. In every case of H. pylori detection, it is important to make a decision about the expediency of eradication therapy. This is particularly significant, since H. pylori eradication has been recognized as an effective method of gastric cancer prevention. In addition, H. pylori eradication therapy in patients suffering from chronic gastritis with dyspepsia symptoms serves as the firstchoice therapy that allows patients with dyspepsia resulting from H. pylori infection to be excluded. The choice of the H. pylori eradication therapy scheme is determined by the protocols (standards) of patient management accepted in the respective CIS country. A high efficacy of H. pylori infection eradication is shown to be provided by bismuthcontaining schemes.Conclusion.  Opportunistic screening of H. pylori is carried out by general practitioners, district physicians, gastroenterologists and other specialists. The most effective method of gastric cancer prevention is the eradication therapy of H. pylori infection in chronic gastritis. The maximal positive potential of such a therapy is realized when it is performed before the atrophic changes of the gastric mucosa have appeared.

Aim. The clinical guidelines are intended to supplement specialty decision-making for improved aid quality in patients with gastritis and duodenitis though acknowledging the latest clinical evidence and principles of evidencebased medicine.Key points. Gastritis is an inflammatory disease of stomach mucosa, with a separate definition of acute and chronic gastritis. Chronic gastritis is a cohort of chronic diseases uniting a typical morphology of persistent inflammatory infiltration, impaired cellular renewal with emergent intestinal metaplasia, atrophy and epithelial dysplasia of gastric mucosa. Oesophagogastroduodenoscopy (OGDS) or high-resolution OGDS with magnified or non-magnified virtual chromoendoscopy, including targeted biopsy for atrophy and intestinal metaplasia grading and neoplasia detection, are recommended to verify gastritis and duodenitis, precancer states and/or gastric mucosal changes. All chronic gastritis patients positive for H. рylori should undergo eradication therapy as aetiological and subsidiary for gastric cancer prevention. Chronic gastritis patients with symptoms of dyspepsia (epigastric pain, burning and congestion, early satiety), also combined with functional dyspepsia, are recommended proton pump inhibitors, prokinetics, rebamipide and bismuth tripotassium dicitrate in symptomatic treatment. With focal restricted intestinal metaplasia, follow-up is not required in most cases, mainly when advanced atrophic gastritis is ruled out in high-quality endoscopy with biopsy. However, a familial history of gastric cancer, incomplete intestinal metaplasia and persistent H. pylori infection render endoscopy monitoring with chromoendoscopy and targeted biopsy desirable once in three years. Patients with advanced atrophic gastritis should have high-quality endoscopy every 3 years, and once in 1–2 years if complicated with a familial history of gastric cancer.Conclusion. The recommendations condense current knowledge on the aetiology and pathogenesis of gastritis and duodenitis, as well as laboratory and instrumental diagnostic techniques, main approaches to aetiological H. pylori eradication and treatment of dyspeptic states.

Helicobacter pylori (H. pylori) has been shown to be a causal factor of gastric cancer in cohort studies and animal models. Meta-analysis of case-control studies nested within prospective cohorts showed that H. pylori infection was associated with a 5.9-fold increased risk of non-cardia gastric cancer. Prospective cohort studies showed that gastric cancer developed in 1–4% of H. pylori-infected subjects. Gastric cancer was successfully induced in Mongolian gerbils and insulin-gastrin (INS-GAS) transgenic mice after inoculation of H. pylori. Meta-analysis of randomized control trials also showed that eradication of H. pylori may reduce the risk of gastric cancer. However, there are several concerns regarding the widespread use of antibiotics to prevent gastric cancer, including the emergence of antibiotic resistance and the perturbation of gut microbiota after H. pylori eradication. Recent studies showed that eradication of H. pylori resulted in an increase in the bacterial diversity and restoration of the relative abundance of other bacteria to levels similar to H. pylori non-infected subjects in the gastric microbiota. The administration of antibiotics may also alter the composition of intestinal microbiota. The α-diversity and β-diversity of fecal microbiota are significantly altered immediately after H. pylori eradication but are gradually restored to levels similar to those before therapy. Yet, the rate of recovery varies with regimens. The diversity was restored at week 8 after triple therapy but was not yet fully recovered at 1 year after concomitant and quadruple therapies. Some studies showed that supplementation of probiotics may reduce the dysbiosis during H. pylori eradication therapy. Although some earlier studies showed high levels of macrolide resistance after triple therapy, recent studies showed that the increased antibiotic resistance rate may be restored 2–12 months after eradication therapy. These results collectively provide evidence of the long-term safety of H. pylori eradication. Yet, more prospective cohort studies and randomized trials are warranted to assess the efficacy and long-term safety of H. pylori eradication for gastric cancer prevention.
