[Gastritis associated with Helicobacter pylori in the material of gastrobiopsies in the group of children with dyspepsia].

Helicobacter pylori (HP) was studied in gastrobiopsies from 180 children, 9 to 17 years old with chronic dyspeptic symptoms. The presence of HP was found in the stomach mucosa of 78.9% patients. The important morphological marker of HP-infection was presence of lymphoid follicles and signs of "active" chronic gastritis in the stomach mucosa (p < 0.001). Thus HP may be considered as an essential pathogenetic factor of chronic dyspeptic syndrome in children of a school age.
