Abstract
Purpose of the study. Compare the effectiveness of different eradication therapy regimens in patients with chronic pancreatitis with concomitant gastritis associated with various genetic variants of H. pylori.Materials and methods: 63 patients with chronic pancreatitis and concomitant Helicobacter pylori-associated gastritis were examined. The control group consisted of 45 patients with chronic gastritis. Diagnosis of chronic pancreatitis was based on anamnestic, clinical data, instrumental studies (MSCT). Diagnosis of H. pylori infection was carried out by the morphological method, 13C urease breath test, and immunoblotting. Statistical processing was carried out using application packages SPSS Statistic 17.0.Results. In patients with chronic pancreatitis, CagA-positive H. pylori strains were found 19.3% less often compared with the control group (p <0.05), VacA-positive—21.9% less often (p <0.05). In the study group, H. pylori genes encoding urease A production and genes encoding the synthesis of H. pylori outer membrane proteins (p33, p30, p29, p26, p19, p17) were significantly more frequently met. In the group of patients with chronic pancreatitis, the standard triple therapy of the 1st line with the inclusion of bismuth tripotassium dicitrate was 86.8% more effective (p <0.01) compared to the standard triple therapy of the 1st line, and the maximum increase in efficiency was observed among owners of H. pylori strains, expressing urease A and with the representation on the outer membrane of the proteins p30, p33, p26, p19, p17 (p <0.01).Conclusion. Eradication therapy in patients with chronic pancreatitis in the presence of pathogenicity complex p30, p33, urease A, p26, p19, p17 in H. pylori according to the standard line triple therapy protocol with the inclusion of bismuth tripotassium dicitrate has advantages compared to the standard triple therapy protocol 1 line (p <0.001).
