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.

Background/Aims: It is still unknown whether cytochrome P450 (CYP) 2C19 polymorphisms influence <i>Helicobacter pylori</i> (<i>H. pylori</i>) eradication, especially in eastern Asia. We aimed to evaluate how changes in proton pump inhibitor (PPI) strategies could be used to overcome the effects of CYP2C19 polymorphism on <i>H. pylori</i> eradication rate when it is used as the second-line regimen after the failure of standard triple therapy.Materials and Methods: We performed a retrospective observation study of 675 patients in whom standard triple therapy for <i>H. pylori</i> infection was not effective between January 2009 to December 2018. All patients underwent a classic bismuth-containing quadruple therapy (10 to 14-day regimen), and their eradication rates were evaluated for several years. We compared the eradication rates in patients with or without the second-line PPI switch. Further, we assessed differences in eradication rates with or without the strategy using esomeprazole and rabeprazole, which are not influenced significantly by CYP2C19 genetic polymorphism.Results: The eradication rate was 81.0% in individuals who received the second-line PPI switch, but it was 74.8% without switching (<i>P</i>=0.14). In the strategy using esomeprazole and rabeprazole, the eradication rate was 84.6%, compared to 76.5% in the control group (<i>P</i>=0.03). Finally, in the group of patients who switched to rabeprazole, the eradication rates were 85.6%, compared to 77.6% in the group who switched to pantoprazole (<i>P</i>=0.05).Conclusions: Switching to PPI, which is not influenced by CYP2C19 genetic polymorphism, increases the efficiency of eradication after the failure of standard triple therapy.

Continuous evaluation of the actual clinical practice of diagnosis and treatment of Helicobacter pylori is crucial in order to provide the best standard of care and to compare health outcomes with expert recommendations. Aim:to evaluate the effectiveness of the standard triple therapy (amoxicillin, clarithromycin, a proton pump inhibitor) and the standard triple therapy plus bismuth tripotassium dicitrate. Materials and methods.Observational, prospective, multicenter study, carried out in one single Russian centre A.S. Loginov Moscow Clinical Scientific Center as part of the Hp-EuReg. Patients were included from 2013 to November 2019 by Russian gastroenterologists. Results.A total of 647 patients were collected and 330 were administered either standard triple therapy ((amoxicillin, clarithromycin, a proton pump inhibitor) or standard triple therapy plus bismuth tripotassium dicitrate. Invasive methods is dominates in the initial diagnosis of H. pylori: the frequency of use of the quick urease test decreased from 50% in 2013 to 31% in 2019. Serology was used in 27.9%. There has been an increase in the use of the13C-urea breath test from 13% in 2013 to 31% in 2019. The histological method (7.5%) and the stool antigen test (3.2%) were used less frequently. For eradication control non-invasive methods are mostly used:13C-UDT (82.7%) and the stool antigen test (14.4%). The effectiveness of standard triple therapy (mITT) was 68% with a 7-day course, 79% with a 10-day course, and 70% with a 14-day course. Combination of bismuth and standard triple therapy eradicates H. pylori (mITT) in 63%, 75% and 89%, respectively. Conclusion.An improvement in the clinical practice of managing patients with H. pylori infections has been noted. The standard triple therapy in combination with bismuth tripotassium dicitrate, prescribed for 14 days, is more effective.

Triple therapy is accepted as the treatment of choice for H. pylori eradication. In industrialized countries, a proton pump inhibitor plus clarithromycin and amoxicillin or nitroimidazole have shown the best results. Our aims were: 1. To study the eradication rate of the association of a proton pump inhibitor plus tinidazole and clarithromycin on H. pylori infection in our population. 2. To determine if previous treatments, gender, age, tobacco, alcohol use, and non-steroidal anti-inflammatory drugs (NSAIDs) change the response to therapy. METHODS: Two hundred patients with peptic ulcer (upper endoscopy) and H. pylori infection (histology and rapid urease test - RUT) were included. A proton pump inhibitor (lansoprazole 30 mg or omeprazole 20 mg), tinidazole 500 mg, and clarithromycin 250 mg were dispensed twice a day for a seven-day period. Eradication was assessed after 10 to 12 weeks of treatment through histology and RUT. RESULTS: The eradication rate of H. pylori per protocol was 65% (128/196 patients). This rate was 53% for previously treated patients, rising to 76% for not previously treated patients, with a statistical difference p<0.01. No significant difference was observed regarding sex, tobacco use, alcohol consumption, and NSAID use, but for elderly patients the difference was p = 0.05. Adherence to treatment was good, and side effects were mild. CONCLUSIONS: A proton pump inhibitor, tinidazole, and clarithromycin bid for seven days resulted in H. pylori eradication in 65% of the patients. Previous treatments were the main cause of treatment failure.

Line Of Therapy

Helicobacter pylori infection, use of nonsteroidal anti-inflammatory drugs (NSAIDs) including aspirin, and smoking are the most important causes of peptic ulcer disease. Peptic ulcer disease is characterized by a history of waxing and waning symptoms of localized, dull, aching pain in the upper abdomen. Bleeding is the most common complication; free perforation of the stomach or duodenum into the peritoneal cavity is uncommon but serious. The diagnosis of peptic ulcer disease is made by endoscopy, which offers an opportunity for biopsy of gastric ulcers (which may be malignant) and reveals important prognostic indicators in patients with bleeding ulcers. A single daily dose of a proton pump inhibitor gives quick relief of symptoms and effective healing of peptic ulcers in 4 to 6 weeks. The management of patients with upper gastrointestinal haemorrhage requires a multidisciplinary medical and surgical approach. Early risk stratification based on clinical and endoscopic criteria allows delivery of appropriate care, with endoscopic intervention now widely accepted as the first line of therapy. This should be followed by administration of a high dose of an intravenous proton pump inhibitor to further reduce recurrent bleeding. Treatment of H. pylori is a cure for peptic ulcer disease in most patients. This usually requires at least two antimicrobial agents, with the most popular triple therapy combining a proton pump inhibitor with any two of amoxicillin, metronidazole, and clarithromycin for 7 to 14 days. Eradication of H. pylori infection, avoidance of high-dose NSAIDs or aspirin, and the maintenance use of proton pump inhibitors in high-risk individuals are the best ways to prevent recurrence of ulcer and ulcer complications.
