Abstract
Aim. Determination of the prevalence of Helicobacter pylori (H. pylori) infection among the population of the Ryazan region.
 Materials and Methods. 833 individuals (809 adults and 24 children) were examined for presence of IgG class antibodies using the enzyme immunoassay (2017-2018). The criteria for inclusion into the study were: a desire of a patient to undergo examination for the presence of antibodies to H. pylori in blood. Criteria for exclusion: past treatment for helicobacteriosis. The presence of helicobacteriosis was determined by enzyme immunoassay for quantitative detection of IgG class antibodies (anti-H. pylori IgG) using BCM Diagnostics Helicobacter pylori IgG (USA) test system and for qualitative determination of IgG antibodies to H. pylori in blood serum on IMMULITE 2000 (Germany; test IMMULITE 2000 H. pylori IgG). Sensitivity of the used test systems was 95.0%, specificity 98.0%.
 Results. High contamination of adult residents of Ryazan with H. pylori 65.6% was found (70.6% of males, 64.4% of females). Prevalence of H. pylori infection among adults in 2017 was 64.4% and in 2018 70.2%, however, the observed increase in the number of infected individuals was not statistically significant (p0.05). The highest prevalence of H. pylori infection was observed in individuals 40 years of age (67.2%). Gender-related differences in the prevalence of Helicobacter pylori infection were revealed in individuals of 40 years and older. H. pylori infection in males of 40 years was 75.2%, against 65.5% in females of the same age (p0.05). In children of 4-16 years, the share of individuals with positive serological test with anti-H. pylori IgG reached 20.8%. All H. pylori infected children were above 9 years of age. Individuals with positive serological tests received consultation of a gastroenterologist, and on indications underwent additional examination with administration of eradication treatment. In patients with indefinite results the examination was repeated after a week and/or the presence of H. pylori antigen in feces was determined.
 Conclusion. The data obtained indicate a high level of infection with H. pylori in the adult population in the Ryazan region 65.6%. The incidence of detection of anti-H. pylori IgG in the population was maximal in individuals 40 years (67.2%).
Highlights
Serological method of determination of H. pylori infection is used in Russia for primary diagnosis in 29.7% of cases, and in cases of low bacterial contamination of gastric mucosa it possesses the highest sensitivity in comparison with other methods of identification of helicobacteriosis [1,3]
The obtained information evidenced a high contagion of population of the Ryazan region with H. pylori and agrees with the existing data for other regions of RF with the prevalence of helicobacteriosis 61-90% [5,6,7]
Contamination with H. pylori starts in childhood and adolescence reaching 20.8%, and further increases with age
Summary
Обследованы 833 человека (809 взрослых и 24 детей) с использованием иммуноферментного метода выявления антител класса IgG (2017-2018). Критерии включения в исследование: желание пациента пройти обследование на наличие в крови антител к H. pylori. Наличие хеликобактериоза определяли иммуноферментным методом количественного выявления антител класса IgG (anti-H. pylori IgG) тест системой BCM Diagnostics Helicobacter pylori IgG (США) и качественного определения IgG антител к H. pylori в сыворотке крови на анализаторе IMMULITE 2000 (Германия; тест IMMULITE® 2000 H. pylori IgG). Наибольшая распространенность хеликобактериоза отмечена у лиц в возрасте ≥40 лет (67,2%). Обнаружены гендерные различия в частоте выявления хеликобактериоза у лиц в возрасте 40 лет и старше: инфицированность H. pylori среди мужчин ≥40 лет составила 75,2% против 65,5% у женщин того же возраста (p
