Rebamipide during chronic gastritis: <i>H. pylori</i> eradication therapy and restoration of gastric mucosa barrier function

H. pylori-Associated Gastritis, Gastritis after H. pylori Eradication and H. pylori-Negative Gastritis: Algorithm of Diagnosis and Treatment (Literature Review and Resolution of the Expert Panel of the Russian Gastroenterological Association)

Aim: to provide the basic points of the Expert Panel of the Russian Gastroenterological Association with discussion of measures to improve diagnostics, treatment and management of chronic gastritis patients.

Key points. In the Russian Federation in 2021 more than 30 million patients diagnosed with “Gastritis and duodenitis” were recorded (K29 in accordance with International Classification of Diseases-10). H. pylori incidence rate in the Russian population has reduced and presently is about 40 %. In chronic gastritis pattern H. pylori-associated gastritis has still dominated though gastritis percent after successful H. pylori eradication, reactive gastropathy (including reflux gastritis) and autoimmune gastritis, has increased. Endoscopic and histologic examinations serve as key diagnostic techniques that provide a means for assessing the ethiology of gastritis, topography and degree of atrophic changes, gastritis staging as per OLGA/OLGIM system that properly correlates with the risk of stomach cancer and determines endoscopic examination strategy. H. pylori eradication therapy of gastritis serves as an etiotropic treatment and makes it possible to prevent progression of atrophy and stomach cancer. Conventional triple therapy combined with bismuth tripotassium dicitrate allows for achieving optimal cure rates of H. pylori eradication. Addition of rebamipide to regimens of H. pylori eradication improves their efficiency. Rebamipide arrests symptoms of dyspepsia in the case of chronic gastritis and functional dyspepsia. The administration of rebamipide for chronic gastritis makes it possible to influence the syndrome of increased epithelial permeability and inflammation, which makes it advisable to study it as a means of preventing stomach cancer and the progression of atrophy in various types of chronic gastritis.

Conclusion. Members of the Expert Panel has approved the algorithm of diagnosis and treatment of H. pylori-associated gastritis, gastritis after H. pylori eradication and H. pylori-negative gastritis at the diagnostic stage in the case of initial presentation and long-term follow-up when needed.
