Immunological indicators of the risk of the transition from chronic gastritis to gastric ulcer in adolescents

As is known, gastric ulcer (GCC) and duodenal ulcer (duodenal ulcer) are chronic, complex-etiology diseases, the mechanism of which is based on complex transformations of nervous, hypothalamic-pituitary, hypothalamic-pituitary-adrenal and local gastroduodenal processes that lead to a change in trophism in the mucous membrane of the stomach and duodenum. In turn, the incipient ulcerative defect is a source of irritation of the enteric receptors, supporting disorders of neurohormonal regulation. Thus, the resulting “vicious circle” causes the chronic course of peptic ulcer disease. During the study of chronic diseases of gastroduodenal localization, including peptic ulcer disease, many doctrines of its occurrence have been proposed. However, the issue of the origin of peptic ulcer disease still remains insufficiently studied; approaches and tactics for managing patients with erosive and ulcerative lesions of the upper gastrointestinal tract are being developed. The aim of the study was to evaluate immunological indicators that determine the risk of chronic gastritis turning into gastric ulcer. The study included 120 children aged 14-17 years, permanently residing in the Bukhara region of the Republic of Uzbekistan. Taking into account the importance of H. Pylori in the development of HCG, patients were distributed depending on the association of HCG with H. Pylori. To study cytokines, blood tests of patients were performed to determine the titer of antibodies (IgG and IdM) to H. Pylori, immunoglobulins A, M, G in blood serum, secretory IgA in oral fluid, IL-1β, IL-10, TNFα, VEGF in the serum of patients. At the same time, blood sampling was carried out in the periods before and 3 weeks (21 days) after treatment. Thus, the study of the value of immunological blood parameters in the progression of HCG to gastric ulcer disease dictates the need to develop immunological indicators for predicting the progression of HCG to gastric ulcer in adolescents. An increase in TNFα levels indicates a high risk of developing gastric ulcer as a result of vascular damage and impaired local circulation. In the study, an established increase in the level of IL-1β indicates activation of the synthesis of proinflammatory cytokines in HCG, especially in HCG associated with H. Pylori. The use of these recommendations contributes to the monitoring of HCG, improving the effectiveness of diagnosis and the correct choice of treatment for patients with HCG, reducing mortality and disability at the same time.
