Background. As part of an observational multicenter prospective study European Registry on the management of Helicobacter pylori infection, conducted on the initiative of the European H. pylori and Microbiota Study Group, the compliance of clinical practice in the management of patients with Helicobacter pylori infection in Kazan with clinical guidelines was assessed. Materials and methods. The data of 437 patients included into the register by clinical sites in Kazan in 20132019 were analyzed. The methods used for the initial diagnosis of H. pylori infection and eradication control were evaluated. The frequency of various eradication therapy regimens prescription was analyzed in 379 cases. Data regarding the effectiveness of eradication therapy was analyzed in 173 patients. Results. The rapid urease test (44.2% of cases) and cytology/histology (60% of cases) were most often used for the initial diagnosis of H. pylori infection; however non-invasive methods such as 13C-urea breath (9.2%), serology (6.2%), H. pylori stool antigen test (2.3%) were less common. In 21.7% of patients two methods of H. pylori detection were used for primary diagnosis. The control test to evaluate the effectiveness of eradication therapy at the recommended timepoint was performed in 46.2% of patients. 13C-urea breath test (31.7%), stool PCR/stool antigen test (28.7%), rapid urease test (22.3%), cytology/histology (26.2% of cases) prevailed in the assessment of eradication rate. Standard triple therapy, including proton pump inhibitor, clarithromycin and amoxicillin was most commonly prescribed as first-line therapy (64.6% of cases). The duration of eradication therapy was 14 days in the majority of cases with pantoprazole as the most common proton pump inhibitor in standard triple therapy regimens (84.8%). The efficacy of 14-day standard triple therapy (mITT) was 87.0%. Conclusion. The results indicate a high frequency of non-invasive methods use for assessing the effectiveness of eradication therapy; however, the overall rate of eradication efficacy assessment is low, limiting the possibility of analyzing the eradication results. The effectiveness of the most common 14-day standard triple first-line therapy in Kazan doesnt reach the recommended 90% eradication level. This could be explained by high rate of pantoprazole use, which is not an optimal proton pump inhibitor in eradication therapy regimens.

Abstract Background: Helicobacter pylori ( H. pylori ) cannot usually be detected in the gastric juice and it is thought that H. pylori may reside under the mucus layer for long term. The mechanisms of action of proton pump inhibitor (PPI)for H. pylori eradication are not entirely clear. Our study aimed to determine the role of PPI on the movement of H. pylori across the mucus layer to the gastric lumen and the mechanism of PPI on H. pylori eradication. Methods: Patients with H. pylori infection were intravenous injected with PPI (intervention group, n=31) or without PPI (control group, n=37). The presence of H. pylori in the gastric juice was evaluated by the rapid urease test (RUT), polymerase chain reaction (PCR), and culture methods. Results: The H. pylori positive detection rates were all significantly higher among patients in the intervention group than among patients in the control group by the RUT ( P < 0.0001), PCR ( P < 0.0001), and culturing ( P = 0.0386). Conclusion: H. pylori can penetrate across the mucus layer to the gastric lumen following PPI intervention, and thus it might represent a novel target in the eradication of H. pylori .

Introduction: The scheme proton pump inhibitor/amoxicillin/clarithromycin (PPI/AC) is still the first-line treatment for Helicobacter pylori (H. pylori) infections despite evidence suggesting its failure in up to 20% to 30% of patients. Methodology: This study involved 493 patients who were prescribed omeprazole (20 mg twice a day) or another proton pump inhibitor in equivalent dosage, amoxicillin (1 g twice a day), and clarithromycin (500 mg twice a day) for seven days. Efficacy was determined by negative urease test and absence of H. pylori on gastric biopsy samples twelve weeks after the end of treatment. Safety was defined according to the adverse effects reported. Mean age of the patients was (± SD) 48.96 ± 13, and demographic and clinical data were recorded for correlation with treatment outcomes. Results: Out of 493 patients, 316 (64.1%) presented duodenal ulcer, 111 (22.5%) gastric ulcer, and 66 (14.4%) simultaneous gastric and duodenal ulcers. Additionally, 267 (54.2%) patients had at least one risk factor for peptic ulcer disease, smoking being the most common (99 [36.5%]). Successful eradication was achieved in 408 patients. The eradication rates per protocol, and according to the intention to treat, were 88.8% and 82.7%, respectively.  Of 164 (35.5%) patients who presented adverse effects, 100 (61%) reported them as mild and only six (3.7%) patients had to discontinue treatment. Previous use of tobacco and non-steroid anti-inflammatory drugs was the only risk factor for treatment failure (P 0.00). Conclusion: PPI/AC is still a valuable and remarkably tolerable option for first-line H. pylori eradication in Brazil.

Background: Laryngopharyngeal reflux is retrograde flow of contents of the stomach to the larynx and the pharynx. The study aims to compare two regimens (proton pump inhibitor monotherapy versus triple therapy) on the outcome of Helicobactor pylori positive laryngopharyngeal reflux disease. Methods: The presence of laryngopharyngeal reflux was determined by reflux symptom index and reflux finding score. The presence of Helicobactor pylori in the tissue was confirmed by rapid urease test. All urease test negative laryngopharyngeal reflux patients were given a course of proton pump inhibitors and results were evaluated. All urease test positive patients were divided into two groups. One group was given a course of proton pump inhibitors and another group was given a course of triple therapy and the results were compared. Results: A total number of 704 laryngopharyngeal reflux patients were screened for urease test. Among them 138 patients (19.6 %) were urease test negative and were given proton pump inhibitor therapy. Improvement in both reflux finding score (average score 11.75) and reflux symptom index (average score 5.25) score was observed after 3 months with p-value<0.05. In urease test positive patients, improvement in scores was observed in both proton pump inhibitors and triple therapy group, however marked improvement in the clinical features was observed in triple therapy group with p-value<0.05. Conclusions: The study reveals association between laryngopharyngeal reflux and Helicobactor pylori. Proton pump inhibitor therapy is sufficient if no Helicobactor pylori is detected, however incase of presence of Helicobactor pylori, triple therapy gives better results.
