Peculiar features of inflammatory process in gastric mucosa with different character of its bacterioviral infection in adolescents with chronic gastritis

Aim. To characterize the inflammatory process in gastric mucosa among adolescents with chronic gastritis in different variants of its bacterioviral infection.

Materials and methods.Clinicoanamnestic, laboratory, endoscopic and morphological examination of 200 adolescents (age range 12–18 years) with chronic gastritis was carried out. In all patients, clinicoanamnestic data, standard laboratory study, esophagogastroduodenoscopy, gastrobiopsy followed by morphological analysis with visual analogue scale were assessed. According to the results of examination, all adolescents were divided into 4 groups depending on the character of bacterioviral infection of gastric mucosa.

Results. No statistically significant differences were detected while comparing the rate of clinical manifestations of pain abdominal, dyspeptic, intoxication and asthenovegetative syndromes as well as changes, revealed in laboratory and ultrasound studies in the above mentioned groups of adolescents. Maximal presentation of macroscopic and pathohistological changes was registered in patients of group 4 (association between colonization of GM with highly pathogenic Hp strains and EBV persistence).

Conclusions. The character of bacterioviral infection of gastric mucosa significantly determines the manifestation degree and activity of inflammatory process. The least degree of manifestation and activity of inflammatory process is registered when mucosa is colonized by low pathogenic Hp strains. Maximal presentation of macroscopic and pathohistological changes in the gastric mucosa is registered in adolescents with associated infection by high pathogenic Hp strains and Epstein-Barr virus. It is manifested by domination of marked and highly active inflammation and appearance of the signs of mucosal atrophy of gastric body and antrum.
