MODERN ASPECTS TO THE PROBLEM OF THE PREVALENCE OF HELICOBACTER PYLORI ASSOCIATED STOMACH DISEASES IN UZBEKISTAN

Abstract

Introduction. We studied the regional epidemiological and genetic characteristics of the prevalence of Helicobacter pylori among the population of Uzbekistan. The work is based on the totality of the results of clinical, biochemical, immunological, genetic and instrumental research methods. Materials and Methods. It was established that Uzbekistan belongs to the regions with a high degree of H. pylori infection of the population (80%). 84% of the population of Uzbekistan have a mixed IceA1- / IceA2-genotype CagA. In peptic ulcer disease, the pathogenic strain CagA + VacA s1, VacA m2 and IceA 1,2 prevails, in chronic gastritis (type B) associated with H. pylori, the strain Cag + VacA s1, VacA m2 and IceA 1. Results and Discussion. The level of resistance of H. pylori strains to clarithromycin reaches 13.3%. Prolongation of eradication therapy up to 10 days and the addition of BTD to it makes it possible to increase the efficiency of H. pylori eradication up to 95%. Conclusion. Due to the presence of HP resistance to clarithromycin in 13.3% of cases and taking into account the low effectiveness of triadotherapy (72.5%), it is advisable to use quadritherapy with the inclusion of BTD in the standard of treatment, which contributes to an increase in the eradication efficiency up to 95%.
