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.

Introduction. Helicobacter pylori and Epstein–Barr virus (EBV) infection have recently been shown to be associated with gastric diseases. Polymorphisms in genes encoding cytokines such as interleukin 10 (IL-10) and interleukin 1 Receptor (IL-1RN) influence cytokine secretion levels and appear to contribute to the risk of developing gastroduodenal diseases. To our knowledge, this is the first preliminary study to address the association of coinfection with H. pylori and EBV and their correlation with genetic predisposition in the development of gastric diseases. Methods. Gastric biopsy samples of 96 patients with different gastric diseases were used. Results. Our results showed that the rate of coinfection was higher in patients with gastric cancer than in patients with normal gastric mucosa, active chronic gastritis, and MALT lymphoma. As regards the characterization of H. pilory strains, the polymorphism s1m1i1 of vacA gene was more frequent in patients with MALT Lymphoma in comparison to others, while the polymorphism s2m2i2 was most frequent in patients with normal gastric mucosa. In addition, patients who tested positive for the cagA gene were more frequently those affected with gastric cancer than those with inactive chronic gastritis. Similarly, the patients with oipA gene ON were more frequently those with gastric cancer than those with inactive chronic gastritis. Conclusion. According to our analysis, there was no correlation between coinfection and polymorphisms in genes encoding IL-10 and IL-1RN. We conclude that various factors can be involved in the development of gastric diseases.

Patients with the digestive form of Chagas'disease frequently present chronic gastritis. As the microorganism Helicobacter pylori is now accepted as the most common cause of human chronic gastritis, the present work was undertaken to verify a possible relationship between the presence of this bacterium and inflammatory changes of antral mucosa in chagasic patients. Seventeen chagasics, with megaesophagus and or megacolon were studied. Fragments from two different regions of antral mucosa were obtained by endoscopy, fixed in 4% neutral formaldehyde and embedded in paraffin. The sections were stained by haematoxylin and eosin for histology analysis, and by carbolfuchsin for H. pylori identification. H. pylori was found in 16 (94.1%) chagasic patients, all of them presenting chronic gastritis. Superficial gastritis was seen in 9 (52.9%) while atrophic gastritis was present in 8 (47.1%) patients. H. pylori was present on gastric mucosa of 8 (100%) patients with atrophic gastritis and of 8 (88.8%) patients with superficial gastritis. We concluded that the microorganism H. pylori should be considered a possible factor connected with the etiopathogenesis of chronic superficial and atrophic gastritis frequently observed in patients with the digestive form of Chagas' disease.

Here we present the current data on the chronic gastritis prevalence in young people. An issue regarding involvement of Helicobacter pylori infection in formation of low bone density is discussed. Examining the features of bone tissue metabolism in infection-associated chronic gastritis to optimize diagnostic algorithm was shown to be of high significance. In the study there were enrolled 200 employees working at the EMERCOM of Russia, who suffered from the acid-dependent gastric diseases and risk factors for reducing bone mineral density. Depending on the bone mineral density parameters, examining functional activity of the gastric mucosa, verification of the H. pylori infection, examining parameters of mineral metabolism, vitamin D level, parathyroid hormone, bone tissue remodeling markers was performed. It was shown that atrophic changes in the gastric mucosa the played a lead role in developing low bone mineral density.

Introduction. Many key questions regarding the etiology, pathogenesis, clinical manifestations and treatment of chronic gastritis remain open. So, despite the success of chronic gastritis pharmacotherapy, much attention is paid to non-drug methods of therapy, in particular, osteopathy. However, evidences of the osteopathic methods effectiveness for the chronic gastritis treatment, obtained by objective instrumental methods, are insufficiently presented in the modern literature.The goal of research — to study the results of osteopathic correction inclusion in the complex therapy of patients with chronic gastritis.Materials and methods. The study involved 50 patients with chronic gastritis, divided by simple randomization into a control group (25 people) and a main group (25 people). The participants in the control group received standard eradication therapy according to a three-component scheme. The participants of the main group additionally received osteopathic correction. In both groups, at the beginning and at the end of the study, there were performed fibroesophagogastroduodenoscopy with targeted biopsy to assess the gastric mucosa state, Helicobacter pylori identification, and intragastric pH-metry to assess gastric juice acidity.Results. According to the study results, a statistically significant (p<0,05) decrease in edema and hyperemia of gastric mucosa was found in the control and main groups. There was a statistically significant (p<0,001) decrease in gastric aciditywith osteopathic accompaniment, compared with unaccompanied drug treatment. In both groups, there was a statistically significant (p<0,05) decrease in the incidence of Helicobacter pylori carriage. Conclusion. Based on the obtained results, it can be assumed that an integrated approach using osteopathic correction in the treatment of chronic gastritis may be more effective than the standard course of treatment.

ABSTRACT Objective: to evaluate the influence of Duodenal reflux in histological changes of the gastric mucosa of rats infected with Helicobacter pylori submitted to pyloroplasty. Methods: after two weeks of acclimation, we infected 30 male Wistar rats with Helicobacter pylori. We randomly divided them into three groups: one submitted to pyloroplasty, another to partial gastrectomy and the third, only infected, was not operated. After six months of surgery, euthanasia was carried out. Gastric fragments were studied by light microscopy to count the number of H. pylori, and to observe the histological changes (gastritis, metaplasia, dysplasia and neoplasia). We confirmed these changes by immunohistochemistry using the molecular markers PCNA and TGF-beta. Results: the animals submitted to pyloroplasty had higher percentage of colonization by H. pylori (median=58.5; gastrectomy=16.5; control=14.5). There was a positive correlation between the amount of H. pylori and the occurrence of chronic gastritis present in the antral fragments. Neoplasia occurred in 40% of rats from the group submitted to pyloroplasty. The staining with PCNA and TGF-ß confirmed the histopathological changes visualized by optical microscopy. Conclusions: the antral region was the one with the highest concentration of H. pylori, regardless of the group. There was a positive correlation between the appearance of benign disorders (chronic gastritis, metaplasia, dysplasia) and cancer in mice infected with H. pylori submitted to pyloroplasty.

Introduction We evaluated the effect of Helicobacter pylori (HP) eradication on p53, cyclin D1 expression, and cell proliferation in gastric mucosa. Materials and Methods We assessed p53, cyclin D1, and ki67 immunoexpression in gastric mucosa from 31 HP chronic gastritis patients and 12 controls. Reassessment was performed 6 months after successful HP eradication. Results Successful eradication resulted in significant decrease of p53 (1.53 ± 0.16 vs 0.83 ± 0.19, P = 0.01) and ki67 (9.84 ± 0.96 vs 4.77 ± 0.27, P < 0.001) staining in the antrum. Similarly, p53 immunoreactivity significantly decreased in the corpus (1.27 ± 0.20 vs 0.46 ± 0.15, P = 0.02), while there was a trend for decreased corpus cyclin D1 and ki67 expression (0.17 ± 0.07 vs 0.0, P = 0.08 and 8.71 ± 1.24 vs 5.85 ± 0.54, P = 0.09, respectively). Importantly, after successful HP eradication, the immunoreactivity of the studied parameters was similar to that of controls. Conclusion Successful HP infection eradication restores p53, cyclin D1, and ki67 immunoreactivity in the gastric mucosa to the level of controls.
