Statistical analysis of the сhronic gastritis in students

Abstract

The aim: The aim of the study is a statistical analysis of the mucosa of the stomach affected by Helicobacter pylori in young people studying at the university. Materials and methods: The work contains the results of the study of chronic gastritis of type B in university volunteer students. The study was attended by students of 1-4 courses, aged 17 to 25 years, a total of 50 people. Among them were 28 men and 22 women. Results: Various forms of chronic gastritis were found in the mucosa of the topographic-anatomical sections of the stomach, 90% of which were associated with Helicobacter pylori (HP). In all departments there is a different amount of common forms of chronic gastritis. In the pyloric section only atrophic gastritis was detected – 31.0 ± 8.5. Atrophic gastritis was also dominant on the lesser curvature – 32.3 ± 7.8, but its forms were significantly (p <0.5) less pronounced than in the pyloric section. In the area of the body, the above variants of chronic gastritis were found in 34.3 ± 8.7 cases, and the majority were flat erosive gastritis 51.0 ± 9.3. There is a tendency to reduce the degree of bacterial contamination of the gastric mucosa from its pyloric section and the lesser curvature to the walls of the body. With a decrease in the degree of bacterial contamination of the gastric mucosa, the degree of leukocyte infiltration also decreases. Between the degree of contamination of the mucous membrane of Helicobacter pylori and the degree of leukocyte infiltration of the mucous membrane, the Pearson correlation coefficient is rxy – 0,935, the correlation is very strong, the coefficient of determination is D=rxy^2 – 0,874, the statistically significant dependence on the probability is 0.99. Conclusions: Atrophic or hyperplastic gastritis associated with HP is found in the gastric mucosa, respectively, 90% of cases. The degree of bacterial contamination correlates with the degree of leukocyte infiltration of the gastric mucosa. Atrophic or hyperplastic gastritis Helicobacter pylori-associated is a common disease of people in young and working age.
