Clinical and functional features of patients with chronic pancreatitis and related helicobacter pylori-associated gastritis

Purpose of the study. To assess the state of the acid-producing function of the stomach in patients with varying degrees of functional insufficiency of the pancreas in the presence of Helicobacter pylori-associated gastritis. Materials and methods: 77 patients with chronic pancreatitis and concomitant Helicobacter pylori-associated gastritis were examined. The control group consisted of 56 patients with chronic pancreatitis without Helicobacter pylori-associated gastritis. Diagnosis of chronic pancreatitis was based on anamnestic, clinical data, instrumental studies (MSCT). The exocrine function of the pancreas was assessed by the content of pancreatic elastase in the feces. Diagnosis of H. pylori infection was carried out by the morphological method, urease respiratory test 13C, by immunoblotting. All patients underwent endoscopic examination of the stomach. In some patients, the level of gastrin 17 in the blood was determined. Statistical processing was carried out using SPSS Statistic 17.0 application software packages. Results. Pain syndrome was significantly more frequently observed in H.pylori- positive patients with chronic pancreatitis (93.2%, p = 0.045), while more often epigastric pain was observed (30.7% versus 12.5% of the control group, p = 0.48). In patients with chronic pancreatitis with an intense pain syndrome, in 66.7% of cases, the combination of proteins p26, p19 and p17 with CagA H.pylori was detected. In patients with chronic pancreatitis with concomitant Helicobacter pylori-associated gastritis, the level of gastrin was outside the normal range in 57.1% of cases (control group - 18.2%, p = 0.048) and was below normal in 42.9% of patients. The average value of gastrin in patients of the studied group was lower (3.140 ± 0.802 pmol / l) than in the control group (4.833 ± 1.594 pmol / l, p = 0.045). In patients with exocrine pancreatic insufficiency, the level of gastrin was reduced / increased in 75% of cases (p = 0.014). In patients with severe chronic pancreatitis, gastrin levels were significantly more often not normal (p = 0.041). CagA VacA - positive strains were statistically significantly more frequently detected in patients with chronic alcoholic pancreatitis and correlated with the severity of the disease. Conclusion. Helicobacter pylori infection contributes to a variety of clinical manifestations in patients with chronic pancreatitis. Helicobacter pylori - a positive status in patients with chronic pancreatitis is associated with more intense gastric acid-induced acid production in the stomach. The severity of morphological changes in chronic pancreatitis, as well as exocrine pancreatic insufficiency correlates with CagA- positive strains of Helicobacter pylori and fluctuations in gastrin levels in the digestive period.
