Purpose – the systematization of data on the resistance of Helicobacter pylori to clarithromycin in the Russian Federation. Material and methods. Necessary investigations were searched in the electronic databases MEDLINE/PubMed, EMBASE, Cochrane, and the Russian Science Citation Index (RSCI), published between January and September, 2020. The final analysis included original publications from periodically reviewed foreign and Russian publications, as well as dissertations that used validated H. pylori resistance assessment tests with detailed descriptive statistics that allow the resulting data to be included in the meta-analysis. Results. The final analysis included 16 studies (1227 isolates). The generalized indicator of H. pylori resistance to clarithromycin in the Russian Federation was 11.85% (95% confidence interval (CI) 7.315–17.302; I2 = 86.19%). When analyzing papers published over the past ten years, H. pylori resistance to clarithromycin was 10.39% (95% CI 7.103–14.219; I2 = 61.29%). In Moscow and the Moscow Region, the generalized indicator of H. pylori resistance to clarithromycin was 10.87% (95% CI 7,280–15,439; I2 = 50.57%), in St. Petersburg – 22.26% (95% CI 9,525–38,470; I2 = 84.75%), Smolensk – 5.74% (95% CI 3,511–8,789; I2 = 0.00%), Kazan – 10.0% (95% CI 5,023–17,355; I2 = 45.22%). Conclusion. The results show that the resistance of H. pylori to clarithromycin in Russia does not exceed the 15% threshold regulated by the Maastricht-V Consensus, which allows us to consider a triple regimen of anti-Helicobacter therapy with clarithromycin as a first-line therapy. At the same time, to achieve the maximum effect when using classical triple therapy and to level the risk of further progression of clarithromycin resistance of H. pylori in Russia, it is advisable to use methods of its optimization. |
