ABSTRACT

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

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.

ABSTRACT

The multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group (EHMSG) is conducted in 27 countries in Europe. The data from the Russian part of the European registry for the management of Helicobacter pylori infection (European Registry on the management of Helicobacter pylori infection, protocol: "Hp-EuReg") allows us to analyze the real clinical practice of diagnosis and treatment of H. pylori and compare it with international recommendations. MATERIALS AND METHODS: A comparative analysis of the data entered in the register by the Russian research centers "Hp-EuReg", in the period from 2013 to 2018, was conducted. RESULTS AND DISCUSSION: Invasive diagnostic methods prevail for the primary diagnosis of H. pylori [histology - 20.3% (in 2013 year) - 43.9% (in 2018 year), rapid urease test - 31.7% and 47.8% respectively]. The most popular mode of eradication therapy is a 10-day triple therapy (62.8-76.2%), the effectiveness of which does not exceed 79% (per protocol). Invasive tests (histology) are the leading method for control the effectiveness of therapy, however, there is a tendency towards a wider use of non-invasive methods (H. pylori stool antigen - from 17% in 2013 to 29.3% in 2018 and urea breath test from 6.9 to 18.3%, respectively). Serological test to control the effectiveness of eradication is still used from 8.2% (2013) to 6.1% (2018). Eradication therapy was not performed in 28% of patients throughout the entire observation period. CONCLUSION: In Russia, despite approved domestic and international recommendations, deviations in clinical practice persist, both during eradication therapy and in monitoring the effectiveness of eradication therapy.

ABSTRACT

AIM: European Registry on the management of Helicobacter pylori infection («Hp-EuReg¼) - a multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group, conducted in 27 European countries in order to evaluate the real clinical practice of diagnosis and treatment of H. pylori and its comparison with international recommendations. MATERIALS AND METHODS: The analysis of 2360 patients entered in the register by the Russian centres of «Hp-EuReg¼ in 2013-2017, who were underwent 1st line eradication therapy. RESULTS: The most common methods of primary diagnosis of H. pylori are histological (37.7%), rapid urease test (29.2%) and serology (29.7%). The duration of eradication therapy in 9.4% of cases was 7 days, in 65.3% - 10 days, and in 25.3% - 14 days. To control the effec- tiveness of treatment, H. pylori antigen in feces (31.3%), urea breath test (23.4%) and histological method (23.3%) were used. In 3.6% cases was used serology by mistake. In 17.3% of patients control was not carried out. The effectiveness of triple therapy with a PPI, amoxicillin, clar- ithromycin (per protocol) was 67.6%, with 7-day course, 81.1% at 10-day and 86.7% at 14-day course. Eradication rate of triple therapy with addition of bismuth (per protocol) reached 90,6% in the group receiving 10-day scheme and 93.6% in the group receiving the 14-day treatment. CONCLUSION: Significant deviations of clinical practice from expert recommendations, most pronounced at the stage of monitoring the effectiveness of therapy, were noted. The suboptimal efficacy of triple therapy is shown.

ABSTRACT

INTRODUCTION: Long-term medical conditions (LTCs) cause reduced health-related quality of life and considerable health service expenditure. Writing therapy has potential to improve physical and mental health in people with LTCs, but its effectiveness is not established. This project aims to establish the clinical and cost-effectiveness of therapeutic writing in LTCs by systematic review and economic evaluation, and to evaluate context and mechanisms by which it might work, through realist synthesis. METHODS: Included are any comparative study of therapeutic writing compared with no writing, waiting list, attention control or placebo writing in patients with any diagnosed LTCs that report at least one of the following: relevant clinical outcomes; quality of life; health service use; psychological, behavioural or social functioning; adherence or adverse events. Searches will be conducted in the main medical databases including MEDLINE, EMBASE, PsycINFO, The Cochrane Library and Science Citation Index. For the realist review, further purposive and iterative searches through snowballing techniques will be undertaken. Inclusions, data extraction and quality assessment will be in duplicate with disagreements resolved through discussion. Quality assessment will include using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Data synthesis will be narrative and tabular with meta-analysis where appropriate. De novo economic modelling will be attempted in one clinical area if sufficient evidence is available and performed according to the National Institute for Health and Care Excellence (NICE) reference case.

ABSTRACT

BACKGROUND: The decreasing efficacy of H. pylori eradication treatments over time makes the search for better regimens and adjuvant medications a priority. AIM: To conduct a meta-analysis of studies comparing rabeprazole or esomeprazole with other proton pump inhibitors (PPI) or with each other in H. pylori eradication treatment. SELECTION OF STUDIES: Randomised clinical trials comparing esomeprazole or rabeprazole with first-generation PPIs (omeprazole-lansoprazole-pantoprazole) or with each other. RESULTS: The meta-analysis (35 studies, 5998 patients) showed higher eradication rates for esomeprazole than for first-generation PPIs: 82.3% vs. 77.6%; OR = 1.32(1.01-1.73); NNT = 21. Rabeprazole also showed better results than first-generation PPIs: 80.5% vs. 76.2%; OR = 1.21(1.02-1.42); NNT = 23. PPI dosage sub-analysis: only esomeprazole 40 mg b.d. improved results [83.5% esomeprazole vs. 72.4% first generation; OR = 2.27(1.07-4.82); NNT = 9]. Whereas rabeprazole 10 and 20 mg b.d. maintained results, esomeprazole 20 mg b.d. obtained lower efficacy. Esomeprazole vs. rabeprazole sub-analysis (five studies): no significant differences were found: 78.7% vs. 76.7%; OR = 0.90(0.70-1.17). CYP2C19 sub-analysis: Genotype did not significantly affect eradication either in first [OR = 1.76(0.99-3.12)] or new generation [OR = 1.19(0.73-1.95)] PPIs. However, sub-analysis considering only extensive metaboliser patients showed higher eradication with new-generation PPIs [OR = 1.37(1.02-1.84)]. CONCLUSIONS: Esomeprazole and rabeprazole show better overall H. pylori eradication rates than first-generation PPIs. This clinical benefit is more pronounced in esomeprazole 40 mg b.d. regimens. In CYP2C19 extensive metabolisers, new-generation PPIs are more effective than first-generation PPIs for H. pylori eradication. However, a general recommendation of using new-generation PPIs in all scenarios remains unclear.
