[Chronic gastroduodenitis, associated and not associated with Helicobacter pylori infection, and its relationship with functional intestinal pathology depending on the content of fecal calprotectin].

BACKGROUND In recent years, the role of chronic gastroduodenitis in the occurrence of functional intestinal diseases within the framework of the crossover syndrome, which occurs against the background of minimal inflammation in the stomach and intestines associated with Helicobacter pylori infection, has become increasingly relevant. AIM To determine the relationship of chronic gastroduodenitis, associated and not associated with H. pylori infection, with the level of fecal calprotectin (FC) and clinical symptoms of functional intestinal disorders. MATERIALS AND METHODS The study included 158 patients with chronic gastroduodenitis: group 1 (80 patients with gastroduodenitis associated with H. pylori infection in the stomach) and group 2 (76 patients without H. pylori infection). All patients had clinical symptoms of the gastrointestinal tract for at least a year. The patients underwent esophagoduodenoscopy and colonoscopy. Verification of H. pylori was based on data from histiobacterioscopy of impression smears from the mucous membrane of the antrum of the stomach. FC content was determined using an express analyzer. RESULTS Patients of the first group significantly more often complained of pain, a burning sensation and fullness after eating in the epigastric region, nausea, belching, heartburn, flatulence, pain along the large intestine, a feeling of incomplete evacuation after defecation compared to the group without H. pylori infection. At the same time, in patients with H. pylori infection, FC values were most often determined in the range from 50 to 200 μg/g - in 28.75%, and in patients not infected with H. pylori infection - 13.15% (p < 0.05). CONCLUSION The studies conducted indicate the presence of a statistically significant relationship between chronic gastroduodenitis and functional intestinal disorders, which can be bidirectional in nature, the basis of which is minimal inflammation caused by the presence of H. pylori infection and increased production of FC.
