Safety profile of Helicobacter pylori eradication treatments: literature review and updated data of the European Registry on Helicobacter pylori management (Hp-EuReg). Expert Opin Drug Saf 2024; 23:553-564. [PMID: 38557327 DOI: 10.1080/14740338.2024.2338245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 03/28/2024] [Indexed: 04/04/2024]
Abstract
INTRODUCTION Helicobacter pylori (H. pylori), the most prevalent chronic infection globally, is the major cause of relevant diseases such as gastric cancer, leading to high morbidity and mortality worldwide. Several studies have focused on optimize H. pylori eradication treatment through combination therapies and antibiotic resistance. However, the adverse events profile and its impact, as a primary outcome, remains underexplored.The aim of this review was to summarize the available data on the safety of the most common regimens for H. pylori eradication and its impact on the compliance. AREAS COVERED This review encompassed the published evidence from the years 2008 to 2023 regarding both the safety and compliance for most common H. pylori eradication regimens. The main sources for this review comprised MEDLINE, PubMed, and Cochrane electronic databases. Furthermore, it included a safety analysis of unpublished data from the European Registry on H. pylori management (Hp-EuReg). EXPERT OPINION Poor compliance is correlated with significantly lower cure rates, and this is a unique modifiable source of H. pylori treatment failure. Eradication treatments have become complex, involving multiple drugs and dosing intervals. Thus, patient education is crucial; doctors must explain to the patient about potential temporary and most often harmless side effects.

Role of compliance in Helicobacter pylori eradication treatment: Results of the European Registry on H. pylori management. United European Gastroenterol J 2024. [PMID: 38685613 DOI: 10.1002/ueg2.12569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 03/04/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Adherence to Helicobacter pylori (H. pylori) eradication treatment is a cornerstone for achieving adequate treatment efficacy. OBJECTIVE To determine which factors influence compliance with treatment. METHODS A systematic prospective non-interventional registry (Hp-EuReg) of the clinical practice of European gastroenterologists. Compliance was considered adequate if ≥90% drug intake. Data were collected until September 2021 using the AEG-REDCap e-CRF and were subjected to quality control. Modified intention-to-treat analyses were performed. Multivariate analysis carried out the factors associated with the effectiveness of treatment and compliance. RESULTS Compliance was inadequate in 646 (1.7%) of 38,698 patients. The non-compliance rate was higher in patients prescribed longer regimens (10-, 14-days) and rescue treatments, patients with uninvestigated dyspepsia/functional dyspepsia, and patients reporting adverse effects. Prevalence of non-adherence was lower for first-line treatment than for rescue treatment (1.5% vs. 2.2%; p < 0.001). Differences in non-adherence in the three most frequent first-line treatments were shown: 1.1% with proton pump inhibitor + clarithromycin + amoxicillin; 2.3% with proton pump inhibitor clarithromycin amoxicillin metronidazole; and 1.8% with bismuth quadruple therapy. These treatments were significantly more effective in compliant than in non-compliant patients: 86% versus 44%, 90% versus 71%, and 93% versus 64%, respectively (p < 0.001). In the multivariate analysis, the variable most significantly associated with higher effectiveness was adequate compliance (odds ratio, 6.3 [95%CI, 5.2-7.7]; p < 0.001). CONCLUSIONS Compliance with Helicobacter pylori eradication treatment is very good. Factors associated with poor compliance include uninvestigated/functional dyspepsia, rescue-treatment, prolonged treatment regimens, the presence of adverse events, and the use of non-bismuth sequential and concomitant treatment. Adequate treatment compliance was the variable most closely associated with successful eradication.

Effectiveness of Helicobacter pylori Treatments According to Antibiotic Resistance. Am J Gastroenterol 2024; 119:646-654. [PMID: 37983769 DOI: 10.14309/ajg.0000000000002600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 10/02/2023] [Indexed: 11/22/2023]
Abstract
INTRODUCTION Antibiotic resistance is one of the main factors that determine the efficacy of treatments to eradicate Helicobacter pylori infection. Our aim was to evaluate the effectiveness of first-line and rescue treatments against H. pylori in Europe according to antibiotics resistance. METHODS Prospective, multicenter, international registry on the management of H. pylori (European Registry on H. pylori Management). All infected and culture-diagnosed adult patients registered in the Spanish Association of Gastroenterology-Research Electronic Data Capture from 2013 to 2021 were included. RESULTS A total of 2,852 naive patients with culture results were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 22%, 27%, and 18%, respectively. The most effective treatment, regardless of resistance, were the 3-in-1 single capsule with bismuth, metronidazole, and tetracycline (91%) and the quadruple with bismuth, offering optimal cure rates even in the presence of bacterial resistance to clarithromycin or metronidazole. The concomitant regimen with tinidazole achieved an eradication rate of 99% (90/91) vs 84% (90/107) with metronidazole. Triple schedules, sequential, or concomitant regimen with metronidazole did not achieve optimal results. A total of 1,118 non-naive patients were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 49%, 41%, and 24%, respectively. The 3-in-1 single capsule (87%) and the triple therapy with levofloxacin (85%) were the only ones that provided encouraging results. DISCUSSION In regions where the antibiotic resistance rate of H. pylori is high, eradication treatment with the 3-in-1 single capsule, the quadruple with bismuth, and concomitant with tinidazole are the best options in naive patients. In non-naive patients, the 3-in-1 single capsule and the triple therapy with levofloxacin provided encouraging results.

Role of proton pump inhibitors dosage and duration in Helicobacter pylori eradication treatment: Results from the European Registry on H. pylori management. United European Gastroenterol J 2024; 12:122-138. [PMID: 38050339 PMCID: PMC10859719 DOI: 10.1002/ueg2.12476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Accepted: 08/15/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND Management of Helicobacter pylori (H. pylori) infection requires co-treatment with proton pump inhibitors (PPIs) and the use of antibiotics to achieve successful eradication. AIM To evaluate the role of dosage of PPIs and the duration of therapy in the effectiveness of H. pylori eradication treatments based on the 'European Registry on Helicobacter pylori management' (Hp-EuReg). METHODS Hp-EuReg is a multicentre, prospective, non-interventionist, international registry on the routine clinical practice of H. pylori management by European gastroenterologists. All infected adult patients were systematically registered from 2013 to 2022. RESULTS Overall, 36,579 patients from five countries with more than 1000 patients were analysed. Optimal (≥90%) first-line-modified intention-to-treat effectiveness was achieved with the following treatments: (1) 14-day therapies with clarithromycin-amoxicillin-bismuth and metronidazole-tetracycline-bismuth, both independently of the PPI dose prescribed; (2) All 10-day (except 10-day standard triple therapy) and 14-day therapies with high-dose PPIs; and (3) 10-day quadruple therapies with clarithromycin-amoxicillin-bismuth, metronidazole-tetracycline-bismuth, and clarithromycin-amoxicillin-metronidazole (sequential), all with standard-dose PPIs. In first-line treatment, optimal effectiveness was obtained with high-dose PPIs in all 14-day treatments, in 10- and 14-day bismuth quadruple therapies and in 10-day sequential with standard-dose PPIs. Optimal second-line effectiveness was achieved with (1) metronidazole-tetracycline-bismuth quadruple therapy for 14- and 10 days with standard and high-dose PPIs, respectively; and (2) levofloxacin-amoxicillin triple therapy for 14 days with high-dose PPIs. None of the 7-day therapies in both treatment lines achieved optimal effectiveness. CONCLUSIONS We recommend, in first-line treatment, the use of high-dose PPIs in 14-day triple therapy and in 10-or 14-day quadruple concomitant therapy in first-line treatment, while standard-dose PPIs would be sufficient in 10-day bismuth quadruple therapies. On the other hand, in second-line treatment, high-dose PPIs would be more beneficial in 14-day triple therapy with levofloxacin and amoxicillin or in 10-day bismuth quadruple therapy either as a three-in-one single capsule or in the traditional scheme.

Sequential versus Standard Triple Therapy for First-Line Helicobacter pylori Eradication: An Update. Antibiotics (Basel) 2024; 13:136. [PMID: 38391522 PMCID: PMC10885881 DOI: 10.3390/antibiotics13020136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/18/2024] [Accepted: 01/19/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND non-bismuth sequential therapy (SEQ) was suggested as a first-line anti-Helicobacter pylori treatment alternative to standard triple therapy (STT). METHODS We conducted a systematic review with a meta-analysis of randomized controlled trials (RCTs) comparing the efficacy of 10-day SEQ vs. STT (of at least 7 days) using bibliographical searches up to July 2021, including treatment-naïve adult or children. The intention-to-treat (ITT) eradication rate and the risk difference (RD) were calculated. RESULTS Overall, 69 RCTs were evaluated, including 19,657 patients (9486 in SEQ; 10,171 in STT). Overall, SEQ was significantly more effective than STT (82% vs. 75%; RD 0.08; p < 0.001). The results were highly heterogeneous (I2 = 68%), and 38 studies did not demonstrate differences between therapies. Subgroup analyses suggested that patients with clarithromycin resistance only and all geographical areas but South America could benefit more from SEQ. Both therapies have evolved over the years, showing similar results when STT lasted 14 days; however, a tendency toward lower SEQ efficacy was noted from 2010 onwards. CONCLUSIONS Prior to 2010, SEQ was significantly more effective than STT, notably when 7-day STT was prescribed. A tendency toward lower differences between SEQ and STT has been noted, especially when using 10-day STT. None of the therapies achieved an optimal efficacy and therefore cannot be recommended as a valid first-line H. pylori treatment.

Bismuth quadruple three-in-one single capsule three times a day increases effectiveness compared with the usual four times a day schedule: results from the European Registry on Helicobacter pylori Management (Hp-EuReg). Gut 2023; 72:2031-2038. [PMID: 37468228 DOI: 10.1136/gutjnl-2022-329259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 06/30/2023] [Indexed: 07/21/2023]
Abstract
BACKGROUND The recommended schedule for single capsule bismuth quadruple therapy (scBQT, Pylera) includes a proton pump inhibitor (PPI) two times a day and three scBQT capsules four times a day. Four times a day treatments are inconvenient and reduce adherence. In contrast, adherence improves with three times a day schedules. In clinical practice, many gastroenterologists use four capsule scBQT three times a day. However, the effectiveness and safety of this latter approach remain uncertain. AIM To assess the effectiveness and safety of scBQT administered three times a day in the patients included in the European Registry on Helicobacter pylori Management (Hp-EuReg). METHODS All Spanish adult patients registered in the Asociación Española de Gastroenterología Research Electronic Data Capture (REDCap) database from June 2013 to March 2021 receiving 10-day scBQT were analysed. Modified intention-to-treat effectiveness, adherence and the safety of scBQT given three times a day were calculated and compared with the four times a day schedule. A multivariate analysis was performed to determine independent factors predicting cure of the infection. RESULTS Of the 3712 cases, 2516 (68%) were four times a day and 1196 (32%) three times a day. Mean age was 51 years, 63% were women and 15% had a peptic ulcer. The three times a day schedule showed significantly better overall cure rates than four times a day (1047/1112, 94%; 95% CI 92.7 to 95.6 vs 2207/2423, 91%; 95% CI 89.9 to 92.2, respectively, p=0.002). Adherence and safety data were similar for both regimens. In the multivariate analysis, three times a day dosage, first-line therapy, use of standard or high-dose PPIs and adherence over 90% were significantly associated with cure of the infection. CONCLUSIONS ScBQT prescribed three times a day was more effective than the traditional four times a day schedule. No differences were observed in treatment adherence or safety.

Abstract
The prevalence of Helicobacter pylori remains high in the older population. Specific age-related peculiarities may impact the outcomes of H. pylori treatment. The aim of the study was to evaluate the diagnostics and effectiveness of H. pylori eradication between the younger and older European populations. "European Registry on H. pylori Management (Hp-EuReg)" data from 2013 to 2022 were analyzed. Patients were divided into older (≥ 60 years) and younger (18-59 years) groups. Modified intention-to-treat (mITT) and per-protocol (PP) analysis was performed. 49,461 patients included of which 14,467 (29%) were older-aged. Concomitant medications and penicillin allergy were more frequent among the older patients. Differences between younger and older populations were observed in treatment duration in first-line treatment and in proton pump inhibitors (PPIs) doses in second-line treatment. The overall incidence of adverse events was lower in the older adults group. The overall first-line treatment mITT effectiveness was 88% in younger and 90% in the older patients (p < 0.05). The overall second-line mITT treatment effectiveness was 84% in both groups. The effectiveness of the most frequent first- and second-line triple therapies was suboptimal (< 90%) in both groups. Optimal efficacy (≥ 90%) was achieved by using bismuth and non-bismuth-based quadruple therapies. In conclusion, the approach to the diagnostics and treatment of H. pylori infection did not generally differ between younger and older patients. Main differences were reported in the concurrent medications, allergy to penicillin and adverse events both in first- and second-line treatment. Optimal effectiveness rates were mostly achieved by using bismuth and non-bismuth-based quadruple therapies. No clinically relevant differences in the effectiveness between the age groups were observed.

Abstract
The segmentation of patients into homogeneous groups could help to improve eradication therapy effectiveness. Our aim was to determine the most important treatment strategies used in Europe, to evaluate first-line treatment effectiveness according to year and country. Data collection: All first-line empirical treatments registered at AEGREDCap in the European Registry on Helicobacter pylori management (Hp-EuReg) from June 2013 to November 2022. A Boruta method determined the "most important" variables related to treatment effectiveness. Data clustering was performed through multi-correspondence analysis of the resulting six most important variables for every year in the 2013-2022 period. Based on 35,852 patients, the average overall treatment effectiveness increased from 87% in 2013 to 93% in 2022. The lowest effectiveness (80%) was obtained in 2016 in cluster #3 encompassing Slovenia, Lithuania, Latvia, and Russia, treated with 7-day triple therapy with amoxicillin-clarithromycin (92% of cases). The highest effectiveness (95%) was achieved in 2022, mostly in Spain (81%), with the bismuth-quadruple therapy, including the single-capsule (64%) and the concomitant treatment with clarithromycin-amoxicillin-metronidazole/tinidazole (34%) with 10 (69%) and 14 (32%) days. Cluster analysis allowed for the identification of patients in homogeneous treatment groups assessing the effectiveness of different first-line treatments depending on therapy scheme, adherence, country, and prescription year.

Abstract
BACKGROUND AND AIMS Several methods are available to diagnose Helicobacter pylori infection. Our objective was to evaluate the tests used for both the initial diagnosis and the confirmation of eradication after treatment in Europe. METHODS The European Registry on the management of Helicobacter pylori infection is an international, multicentre, prospective, non-interventional registry aiming to evaluate the management of Helicobacter pylori-infected patients in Europe. Countries with at least 100 cases registered from June 2013 to April 2021, and with a validated diagnostic method were analysed. Data were quality reviewed. RESULTS A total of 34,920 adult patients from 20 countries were included (mean age 51 years; 61% women). To establish the initial diagnosis, invasive tests were performed in 19,801 (71%) patients, non-invasive in 11,369 (41%), and both in 3437 (12%). The most frequent were histology (n = 11,885; 43%), a rapid urease test (n = 10,636; 38%) and an urea breath test (n = 7577; 27%). According to the age, invasive tests were indicated in 11,179 (77%) ≥50 years, and in 8603 (65%) <50 years. Depending on the country, the use of invasive tests ranged from 29-99% in <50 years to 60-99% in ≥50. Most of the tests used to confirm eradication were non-invasive (n = 32,540; 93%), with the urea breath test being the most frequent (n = 32,540; 78%). In 2983 (9%) post-treatment tests, histology (n = 1887; 5%) or a rapid urease test (n = 1223; 4%) were performed. CONCLUSION A great heterogeneity was observed for the initial diagnosis and confirmation of the eradication. The reasons for the apparent lack of adherence to the clinical guidelines should be further explored.

Abstract
BACKGROUND AND AIMS The optimal management of naïve and not naïve Helicobacter pylori patients remains unclear. Therefore, it is essential to evaluate whether the actual clinical practice mirrors the indications suggested by the guidelines. This study aimed to assess the effectiveness and the safety of the empirical first- and second-line treatments prescribed to patients enroled at Italian centres participating in the European Registry on H. pylori Management (Hp-EuReg). METHODS The Hp-EuReg is an international multicentre prospective non-interventional registry starting in 2013 aiming to evaluate the management of H. pylori infection by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap. Variables assessed included demographics, previous eradication attempts, treatment regimen, effectiveness, and tolerance. RESULTS Overall, 3723 patients from 2013 to February 2021 were included: 2996 and 727 received an empirical first- and second-line treatment, respectively. According to the modified ITT analysis, among the first-line regimens, only the bismuth quadruple therapy with three-in-one-single capsule (BQT-TSC), the concomitant, and the sequential treatment - all lasting 10 days - achieved an eradication rate >90%. Among the second-line regimens, only the 10-day BQT-TSC reported an effectiveness >90%. High-dose PPI twice daily also significantly increased the effectiveness of some therapies. The BQT-TSC was the regimen with the highest incidence of adverse events. CONCLUSIONS Only quadruple therapies lasting at least 10 days achieved over 90% eradication rates among the empirical first- and second-line regimens. It remains unclear whether high-dose PPI twice daily can improve the efficacy of quadruple treatment.

Abstract
OBJECTIVE To evaluate the use, effectiveness and safety of Helicobacter pylori empirical rescue therapy in third and subsequent treatment lines in Europe. DESIGN International, prospective, non-interventional registry of the clinical practice of European gastroenterologists. Data were collected and quality reviewed until October 2021 at Asociación Española de Gastroenterología-Research Electronic Data Capture. All cases with three or more empirical eradication attempts were assessed for effectiveness by modified intention-to-treat and per-protocol analysis. RESULTS Overall, 2144 treatments were included: 1519, 439, 145 and 41 cases from third, fourth, fifth and sixth treatment lines, respectively. Sixty different therapies were used; the 15 most frequently prescribed encompassed >90% of cases. Overall effectiveness remained <90% in all therapies. Optimised treatments achieved a higher eradication rate than non-optimised (78% vs 67%, p<0.0001). From 2017 to 2021, only 44% of treatments other than 10-day single-capsule therapy used high proton-pump inhibitor doses and lasted ≥14 days. Quadruple therapy containing metronidazole, tetracycline and bismuth achieved optimal eradication rates only when prescribed as third-line treatment, either as 10-day single-capsule therapy (87%) or as 14-day traditional therapy with tetracycline hydrochloride (95%). Triple amoxicillin-levofloxacin therapy achieved 90% effectiveness in Eastern Europe only or when optimised. The overall incidence of adverse events was 31%. CONCLUSION Empirical rescue treatment in third and subsequent lines achieved suboptimal effectiveness in most European regions. Only quadruple bismuth-metronidazole-tetracycline (10-day single-capsule or 14-day traditional scheme) and triple amoxicillin-levofloxacin therapies reached acceptable outcomes in some settings. Compliance with empirical therapy optimisation principles is still poor 5 years after clinical practice guidelines update. TRIAL REGISTRATION NUMBER NCT02328131.

Empirical Second-Line Therapy in 5000 Patients of the European Registry on Helicobacter pylori Management (Hp-EuReg). Clin Gastroenterol Hepatol 2022; 20:2243-2257. [PMID: 34954341 DOI: 10.1016/j.cgh.2021.12.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 12/14/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS After a first Helicobacter pylori eradication attempt, approximately 20% of patients will remain infected. The aim of the current study was to assess the effectiveness and safety of second-line empiric treatment in Europe. METHODS This international, multicenter, prospective, non-interventional registry aimed to evaluate the decisions and outcomes of H pylori management by European gastroenterologists. All infected adult cases with a previous eradication treatment attempt were registered with the Spanish Association of Gastroenterology-Research Electronic Data Capture until February 2021. Patients allergic to penicillin and those who received susceptibility-guided therapy were excluded. Data monitoring was performed to ensure data quality. RESULTS Overall, 5055 patients received empiric second-line treatment. Triple therapy with amoxicillin and levofloxacin was prescribed most commonly (33%). The overall effectiveness was 82% by modified intention-to-treat analysis and 83% in the per-protocol population. After failure of first-line clarithromycin-containing treatment, optimal eradication (>90%) was obtained with moxifloxacin-containing triple therapy or levofloxacin-containing quadruple therapy (with bismuth). In patients receiving triple therapy containing levofloxacin or moxifloxacin, and levofloxacin-bismuth quadruple treatment, cure rates were optimized with 14-day regimens using high doses of proton pump inhibitors. However, 3-in-1 single capsule or levofloxacin-bismuth quadruple therapy produced reliable eradication rates regardless of proton pump inhibitor dose, duration of therapy, or previous first-line treatment. The overall incidence of adverse events was 28%, and most (85%) were mild. Three patients developed serious adverse events (0.3%) requiring hospitalization. CONCLUSIONS Empiric second-line regimens including 14-day quinolone triple therapies, 14-day levofloxacin-bismuth quadruple therapy, 14-day tetracycline-bismuth classic quadruple therapy, and 10-day bismuth quadruple therapy (as a single capsule) provided optimal effectiveness. However, many other second-line treatments evaluated reported low eradication rates. ClincialTrials.gov number: NCT02328131.

Empirical vs. Susceptibility-Guided Treatment of Helicobacter pylori Infection: A Systematic Review and Meta-Analysis. Front Microbiol 2022; 13:913436. [PMID: 35774456 PMCID: PMC9237546 DOI: 10.3389/fmicb.2022.913436] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 05/17/2022] [Indexed: 01/30/2023] Open
Abstract
Background Treating Helicobacter pylori infection according to antibiotic resistance has been frequently recommended. However, information on its real effectiveness is scarce. Aim The aim of this study is to perform a meta-analysis comparing empirical vs. susceptibility-guided treatment of H. pylori. Methods Selection of studies: Studies comparing empirical versus susceptibility-guided treatment were selected. Search strategy: electronic and manual up to August 2021. Data synthesis: by intention-to-treat (random-effects model). Results Overall, 54 studies were included (6,705 patients in the susceptibility-guided group and 7,895 in the empirical group). H. pylori eradication rate was 86 vs. 76%, respectively (RR: 1.12; 95% CI: 1.08-1.17; I 2: 83%). Similar results were found when only RCTs were evaluated (24 studies; RR: 1.16; 95% CI: 1.11-1.22; I 2: 71%) and when susceptibility testing was assessed by culture (RR: 1.12; 95% CI: 1.06-1.18) or PCR (RR: 1.14; 95% CI: 1.05-1.23). For first-line treatments (naïve patients; 30 studies), better efficacy results were obtained with the susceptibility-guided strategy (RR: 1.15; 95% CI: 1.11-1.20; I 2: 79%). However, for empirical first-line quadruple regimens, in particular (both with and without bismuth, excluding the suboptimal triple therapies), not based on CYP2C19 gene polymorphism, no differences in efficacy were found compared with the susceptibility-guided group (RR: 1.04; 95% CI: 0.99-1.09); this lack of difference was confirmed in RCTs (RR: 1.05; 95% CI: 0.99-1.12). For rescue therapies (13 studies, most 2nd-line), similar results were demonstrated for both strategies, including all studies (RR: 1.09; 95% CI: 0.97-1.22; I 2: 82%) and when only RCTs were considered (RR: 1.15; 95% CI: 0.97-1.36). Conclusion The benefit of susceptibility-guided treatment over empirical treatment of H. pylori infection could not be demonstrated, either in first-line (if the most updated quadruple regimens are prescribed) or in rescue therapies.

Abstract
Helicobacter pylori infection is very common in the Spanish population and represents the main cause of chronic gastritis, peptic ulcer, and gastric cancer. The last iteration of Spanish consensus guidelines on H. pylori infection was conducted in 2016. Recent changes in therapeutic schemes along with increasing supporting evidence were key for developing the V Spanish Consensus Conference (May 2021). Fourteen experts performed a systematic review of the scientific evidence and developed a series of recommendations that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. An eradication therapy, when prescribed empirically, is considered acceptable when it reliably achieves, or preferably surpass, 90% cure rates. Currently, only quadruple therapies (with or without bismuth) and generally lasting 14 days, accomplish this goal in first- and second-line therapies. A non-bismuth quadruple concomitant regimen (proton pump inhibitor, clarithromycin, amoxicillin, and metronidazole) or a quadruple bismuth-based combination (proton pump inhibitor, bismuth, tetracycline, and metronidazole), are recommended as first-line regimens. Rescue therapies after eradication failure and management of H. pylori infection in peptic ulcer disease were also reviewed.

Experience with Rifabutin-Containing Therapy in 500 Patients from the European Registry on Helicobacter pylori Management (Hp-EuReg). J Clin Med 2022; 11:jcm11061658. [PMID: 35329984 PMCID: PMC8949410 DOI: 10.3390/jcm11061658] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 03/07/2022] [Accepted: 03/11/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND First-line Helicobacter pylori (H. pylori) treatments have been relatively well evaluated; however, it remains necessary to identify the most effective rescue treatments. Our aim was to assess the effectiveness and safety of H. pylori regimens containing rifabutin. METHODS International multicentre prospective non-interventional European Registry on H. pylori Management (Hp-EuReg). Patients treated with rifabutin were registered in AEG-REDCap e-CRF from 2013 to 2021. Modified intention-to-treat and per-protocol analyses were performed. Data were subject to quality control. RESULTS Overall, 500 patients included in the Hp-EuReg were treated with rifabutin (mean age 52 years, 72% female, 63% with dyspepsia, 4% with peptic ulcer). Culture was performed in 63% of cases: dual resistance (to both clarithromycin and metronidazole) was reported in 46% of the cases, and triple resistance (to clarithromycin, metronidazole, and levofloxacin) in 39%. In 87% of cases rifabutin was utilised as part of a triple therapy together with amoxicillin and a proton-pump-inhibitor, and in an additional 6% of the patients, bismuth was added to this triple regimen. Rifabutin was mainly used in second-line (32%), third-line (25%), and fourth-line (27%) regimens, achieving overall 78%, 80% and 66% effectiveness by modified intention-to-treat, respectively. Compliance with treatment was 89%. At least one adverse event was registered in 26% of the patients (most frequently nausea), and one serious adverse event (0.2%) was reported in one patient with leukopenia and thrombocytopenia with fever requiring hospitalisation. CONCLUSION Rifabutin-containing therapy represents an effective and safe strategy after one or even several failures of H. pylori eradication treatment.

Abstract
BACKGROUND Managing Helicobacter pylori infection requires constant decision making, and each decision is open to possible errors. AIM The aim was to evaluate common mistakes in the eradication of H. pylori, based on the "European Registry on Helicobacter pylori management". METHODS European Registry on Helicobacter pylori management is an international multicentre prospective noninterventional registry evaluating the decisions and outcomes of H. pylori management by European gastroenterologists in routine clinical practice. RESULTS Countries recruiting more than 1000 patients were included (26,340 patients). The most common mistakes (percentages) were: (1) To use the standard triple therapy where it is ineffective (46%). (2) To prescribe eradication therapy for only 7 to 10 days (69%). (3) To use a low dose of proton pump inhibitors (48%). (4) In patients allergic to penicillin, to prescribe always a triple therapy with clarithromycin and metronidazole (38%). (5) To repeat certain antibiotics after eradication failure (>15%). (6) Failing to consider the importance of compliance with treatment (2%). (7) Not to check the eradication success (6%). Time-trend analyses showed progressive greater compliance with current clinical guidelines. CONCLUSION The management of H. pylori infection by some European gastroenterologists is heterogeneous, frequently suboptimal and discrepant with current recommendations. Clinical practice is constantly adapting to updated recommendations, although this shift is delayed and slow.

Abstract
Background Helicobacter pylori (H. pylori) is the most common chronic bacterial infection. Its management has to rely on local effectiveness, given the geographical variability of bacterial antibiotic resistance. We evaluated treatment effectiveness in naïve patients in Greece, as part of the European Registry on the management of H. pylori (Hp-EuReg). Methods Patients were registered in the AEG-REDCap Electronic Case Report Form from 2013-2020. All cases with a first-line treatment were included. Modified intention-to-treat (mITT) analysis was used. Results A total of 547 patients from 5 medical institutions were treated with the following regimens: concomitant with proton pump inhibitors (PPIs), clarithromycin, amoxicillin and metronidazole (concomitant-C+A+M) (38%); hybrid with PPI, clarithromycin, amoxicillin and metronidazole (hybrid-C+A+M) (20%); sequential with PPI, clarithromycin, amoxicillin and tinidazole (sequential-C+A+T) (12%); sequential with PPI, clarithromycin, amoxicillin and metronidazole (sequential-C+A+M) (12%); concomitant with PPI, clarithromycin, amoxicillin and tinidazole (concomitant-C+A+T) (8%); triple with PPI, clarithromycin and amoxicillin (triple-C+A) (7%); and other (3%). Overall compliance was 99%. Triple-C+A, sequential-C+A+T, sequential-C+A+M and concomitant-C+A+T were used from 2013-2015. The respective mITT cure rates (95% confidence interval) were 92% (78-98), 87% (76-94), 67% (54-78) and 91% (79-98). Since 2015, patients were also treated with concomitant-C+A+M and hybrid-C+A+M regimens, with respective mITT cure rates of 90% (85-94) and 88% (80.5-94). Adverse events were reported by 31% of the patients, dysgeusia being the most frequent (15%). Conclusions “Optimized” H. pylori therapies should achieve cure rates over 90%. In Greece, at present, only non-bismuth quadruple concomitant regimens achieve this target and can be recommended as first-line treatment.

Evaluation of the Effectiveness of Helicobacter pylori Eradication Regimens in Lithuania during the Years 2013-2020: Data from the European Registry on Helicobacter pylori Management (Hp-EuReg). ACTA ACUST UNITED AC 2021; 57:medicina57070642. [PMID: 34201428 PMCID: PMC8305910 DOI: 10.3390/medicina57070642] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/10/2021] [Accepted: 06/15/2021] [Indexed: 12/11/2022]
Abstract
Background and Objectives: The prevalence of H. pylori in Eastern Europe remains quite high; however, there is insufficient data on the eradication regimens and their effectiveness. Therefore, the objective of the study was to evaluate the diagnostic methods and treatment of H. pylori infection as well as their adherence to Maastricht V/Florence consensus during the years 2013–2020 in Lithuania. Materials and Methods: Sub-study of the “European Registry on H. pylori Management” (Hp-EuReg), international multicenter prospective non-interventional registry of the routine clinical practice. Lithuanian data from the years 2013–2020 were analyzed for effectiveness on a modified intention-to-treat (mITT) basis. 2000 adult patients, diagnosed with H. pylori infection, were included. Data were compared to the European Maastricht V guidelines. Results: Triple-therapy was used in 90% of the cases. In 91% of the first-line prescriptions, standard triple therapy (STT) was used. The most common second-line treatment was a combination of PPI, amoxicillin and levofloxacin (PPI+A+L) (47%). The overall effectiveness in 552 cases valid for analysis was 90% by mITT. In first-line treatment, the STT effectiveness was 90% and second-line treatment with PPI+A+L achieved 92% by mITT. Increasing overall H. pylori eradication rates were observed: from 72% in 2013 to more than 90% in 2018–2020, as well as a shift from 7 to 10–14 days treatments duration throughout 2013–2020. Conclusions: In Lithuania, the prescribed eradication regimens for H. pylori were in accordance with the international guidelines but diagnostic methods and treatment duration only partially met Maastricht V/Florence guidelines. The eradication effectiveness was improved progressively during the years 2018–2020, reaching ≥90% cure rates.

Abstract
INTRODUCTION The safety of Helicobacter pylori eradication treatments and to what extent adverse events (AEs) influence therapeutic compliance in clinical practice are hardly known. Our aim was to assess the frequency, type, intensity, and duration of AEs, and their impact on compliance, for the most frequently used treatments in the "European Registry on Helicobacter pylori management." METHODS Systematic prospective noninterventional registry of the clinical practice of European gastroenterologists (27 countries, 300 investigators) on the management of H. pylori infection in routine clinical practice. All prescribed eradication treatments and their corresponding safety profile were recorded. AEs were classified depending on the intensity of symptoms as mild/moderate/severe and as serious AEs. All data were subject to quality control. RESULTS The different treatments prescribed to 22,492 patients caused at least 1 AE in 23% of the cases; the classic bismuth-based quadruple therapy was the worst tolerated (37% of AEs). Taste disturbance (7%), diarrhea (7%), nausea (6%), and abdominal pain (3%) were the most frequent AEs. The majority of AEs were mild (57%), 6% were severe, and only 0.08% were serious, with an average duration of 7 days. The treatment compliance rate was 97%. Only 1.3% of the patients discontinued treatment due to AEs. Longer treatment durations were significantly associated with a higher incidence of AEs in standard triple, concomitant, bismuth quadruple, and levofloxacin triple or quadruple therapies. DISCUSSION Helicobacter pylori eradication treatment frequently induces AEs, although they are usually mild and of limited duration. Their appearance does not interfere significantly with treatment compliance.

Abstract
Loss of response to antitumor necrosis factor (anti-TNF) therapies in inflammatory bowel disease occurs in a high proportion of patients. Our aim was to evaluate the loss of response to anti-TNF therapy, considered as the need for dose intensification (DI), DI effectiveness and the possible variables influencing its requirements. Bibliographical searches were performed. SELECTION prospective and retrospective studies assessing DI in Crohn's disease and ulcerative colitis patients treated for at least 12 weeks with an anti-TNF drug. EXCLUSION CRITERIA studies using anti-TNF as a prophylaxis for the postoperative recurrence in Crohn's disease or those where DI was based on therapeutic drug monitoring. DATA SYNTHESIS effectiveness by intention-to-treat (random effects model). Data were stratified by medical condition (ulcerative colitis vs. Crohn's disease), anti-TNF drug and follow-up. RESULTS One hundred and seventy-three studies (33,241 patients) were included. Overall rate of the DI requirement after 12 months was 28% (95% CI 24-32, I2 = 96%, 41 studies) in naïve patients and 39% (95% CI 31-47, I2 = 86%, 18 studies) in non-naïve patients. The DI requirement rate was higher both in those with prior anti-TNF exposure (p = 0.01) and with ulcerative colitis (p = 0.02). The DI requirement rate in naïve patients after 36 months was 35% (95% CI 28-43%; I2 = 98%; 18 studies). The overall short-term response and remission rates of empirical DI in naïve patients were 63% (95% CI 48-78%; I2 = 99%; 32 studies) and 48% (95% CI: 39-58%; I2 = 92%; 25 studies), respectively. The loss of response to anti-TNF agents-and, consequently, DI-occurred frequently in inflammatory bowel disease (approximately in one-fourth at one year and in one-third at 3 years). Empirical DI was a relatively effective therapeutic option.

Abstract
Background There has been resurgence in the use of bismuth quadruple therapy (proton pump inhibitor, bismuth, tetracycline and metronidazole) for treating Helicobacter pylori infection thanks to a three‐in‐one single‐capsule formulation. Objective To evaluate the effectiveness and safety of the single‐capsule bismuth quadruple therapy. Methods Data were collected in a multicentre, prospective registry of the clinical practice of gastroenterologists on the management of H. pylori infection, where patients were registered at the Asociación Española de Gastroenterologia REDCap database on an electronic case report form until January 2020. Effectiveness by modified intention‐to‐treat and per‐protocol as well as multivariable analysis were performed. Independent factors evaluated were: age, gender, indication, compliance, proton pump inhibitor dose and treatment line. Results Finally, 2100 patients were prescribed single‐capsule bismuth quadruple therapy following the technical sheet (i.e., three capsules every 6 h for 10 days). The majority of these patients were naive (64%), with an average age of 50 years, 64% women and 16% with peptic ulcer. An overall modified intention‐to‐treat effectiveness of 92% was achieved. Eradication was over 90% in first‐line treatment (95% modified intention‐to‐treat, n = 1166), and this was maintained as a rescue therapy, both in second (89% modified intention‐to‐treat, n = 375) and subsequent lines of therapy (third to sixth line: 92% modified intention‐to‐treat, n = 236). Compliance was the factor most closely associated with treatment effectiveness. Adverse events were generally mild to moderate, and 3% of patients reported a severe adverse event, leading to discontinuation of treatment in 1.7% of cases. Conclusions Single‐capsule bismuth quadruple therapy achieved H. pylori eradication in approximately 90% of patients in real‐world clinical practice, both as a first‐line and rescue treatment, with good compliance and a favourable safety profile. The development of a three‐in‐one single‐capsule formulation has led to a resurgence in the use of bismuth quadruple therapy (BQT) to treat Helicobacter pylori infection. In the largest study carried out to date, the effectiveness of single‐capsule BQT was optimal both as a firstline and as a rescue therapy. Compliance was the factor most closely associated with treatment effectiveness. Single‐capsule BQT eradicates H. pylori in approximately 90% of patients in real‐world clinical practice, with a favourable safety profile.

Abstract
OBJECTIVE The best approach for Helicobacter pylori management remains unclear. An audit process is essential to ensure clinical practice is aligned with best standards of care. DESIGN International multicentre prospective non-interventional registry starting in 2013 aimed to evaluate the decisions and outcomes in H. pylori management by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap. Variables included demographics, previous eradication attempts, prescribed treatment, adverse events and outcomes. Data monitoring was performed to ensure data quality. Time-trend and geographical analyses were performed. RESULTS 30 394 patients from 27 European countries were evaluated and 21 533 (78%) first-line empirical H. pylori treatments were included for analysis. Pretreatment resistance rates were 23% to clarithromycin, 32% to metronidazole and 13% to both. Triple therapy with amoxicillin and clarithromycin was most commonly prescribed (39%), achieving 81.5% modified intention-to-treat eradication rate. Over 90% eradication was obtained only with 10-day bismuth quadruple or 14-day concomitant treatments. Longer treatment duration, higher acid inhibition and compliance were associated with higher eradication rates. Time-trend analysis showed a region-dependent shift in prescriptions including abandoning triple therapies, using higher acid-inhibition and longer treatments, which was associated with an overall effectiveness increase (84%-90%). CONCLUSION Management of H. pylori infection by European gastroenterologists is heterogeneous, suboptimal and discrepant with current recommendations. Only quadruple therapies lasting at least 10 days are able to achieve over 90% eradication rates. European recommendations are being slowly and heterogeneously incorporated into routine clinical practice, which was associated with a corresponding increase in effectiveness.

Abstract
BACKGROUND The antibiotic resistance profile of Helicobacter pylori (H. pylori) is constantly changing. Up-to-date and reliable data for the effectiveness of first-line H. pylori treatment protocols are necessary to provide evidence-based best-practice guidelines. OBJECTIVES To determine the effectiveness, compliance and safety of first-line treatment for H. pylori in Israel. METHODS An observational, prospective, multicenter study was conducted in tertiary referral centers in Israel, as part of the European registry on H. pylori management (Hp-EuReg). H. pylori-infected patients were included from 2013 to March 2020. Data collected included demographics, clinical data, diagnostic tests, previous eradication attempts, current treatment, compliance, adverse events, and treatment outcome result. RESULTS In total, 242 patients were registered, including 121 (50%) who received first-line therapy, 41% of these individuals received clarithromycin based triple therapy and 58.9% received a four-drug regimen. The overall effectiveness of first-line therapy was 85% and 86% by modified intention-to-treat and per protocol analyses, respectively. The effectiveness of both sequential and concomitant therapies was 100% while clarithromycin-based triple therapy achieved an eradication rate of 79%. Treatment eradication was higher among patients who received high dose proton pump inhibitor (PPI) compared to those treated with low dose PPI (100% vs. 81.5% respectively, P < 0.01). No difference in treatment effectiveness was found between 7-, 10-, and 14-day treatment. CONCLUSIONS The effectiveness of clarithromycin-based triple therapy is suboptimal. First-line treatment of H. pylori infection should consist of four drugs, including high dose PPI, according to international guidelines.

Bismuth quadruple regimen with tetracycline or doxycycline versus three-in-one single capsule as third-line rescue therapy for Helicobacter pylori infection: Spanish data of the European Helicobacter pylori Registry (Hp-EuReg). Helicobacter 2020; 25:e12722. [PMID: 32656898 DOI: 10.1111/hel.12722] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 06/11/2020] [Accepted: 06/12/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Different bismuth quadruple therapies containing proton-pump inhibitors, bismuth salts, metronidazole, and a tetracycline have been recommended as third-line Helicobacter pylori eradication treatment after failure with clarithromycin and levofloxacin. AIM To evaluate the efficacy and safety of third-line treatments with bismuth, metronidazole, and either tetracycline or doxycycline. METHODS Sub-study with Spanish data of the "European Registry on H pylori Management" (Hp-EuReg), international multicenter prospective non-interventional Registry of the routine clinical practice of gastroenterologists. After previous failure with clarithromycin- and levofloxacin-containing therapies, patients receiving a third-line regimen with 10/14-day bismuth salts, metronidazole, and either tetracycline (BQT-Tet) or doxycycline (BQT-Dox), or single capsule (BQT-three-in-one) were included. Data were registered at AEG-REDCap database. Univariate and multivariate analyses were performed. RESULTS Four-hundred and fifty-four patients have been treated so far: 85 with BQT-Tet, 94 with BQT-Dox, and 275 with BQT-three-in-one. Average age was 53 years, 68% were women. Overall modified intention-to-treat and per-protocol eradication rates were 81% (BQT-Dox: 65%, BQT-Tet: 76%, BQT-three-in-one: 88%) and 82% (BQT-Dox: 66%, BQT-Tet: 77%, BQT-three-in-one: 88%), respectively. By logistic regression, higher eradication rates were associated with compliance (OR = 2.96; 95% CI = 1.01-8.84) and no prior metronidazole use (OR = 1.96; 95% CI = 1.15-3.33); BQT-three-in-one was superior to BQT-Dox (OR = 4.46; 95% CI = 2.51-8.27), and BQT-Tet was marginally superior to BQT-Dox (OR = 1.67; 95% CI = 0.85-3.29). CONCLUSION Third-line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10-day BQT-three-in-one or 14-day BQT-Tet. Doxycycline seems to be less effective and therefore should not be recommended.

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.

Helicobacter pylori first-line and rescue treatments in patients allergic to penicillin: Experience from the European Registry on H pylori management (Hp-EuReg). Helicobacter 2020; 25:e12686. [PMID: 32173974 DOI: 10.1111/hel.12686] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 02/08/2020] [Accepted: 02/10/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Experience in Helicobacter pylori eradication treatment of patients allergic to penicillin is very scarce. A triple combination with a PPI, clarithromycin (C), and metronidazole (M) is often prescribed as the first option, although more recently the use of a quadruple therapy with PPI, bismuth (B), tetracycline (T), and M has been recommended. AIM To evaluate the efficacy and safety of first-line and rescue treatments in patients allergic to penicillin in the "European Registry of H pylori management" (Hp-EuReg). METHODS A systematic prospective registry of the clinical practice of European gastroenterologists (27 countries, 300 investigators) on the management of H pylori infection. An e-CRF was created on AEG-REDCap. Patients with penicillin allergy were analyzed until June 2019. RESULTS One-thousand eighty-four patients allergic to penicillin were analyzed. The most frequently prescribed first-line treatments were as follows: PPI + C + M (n = 285) and PPI + B + T + M (classic or Pylera® ; n = 250). In first line, the efficacy of PPI + C + M was 69%, while PPI + B + T + M reached 91% (P < .001). In second line, after the failure of PPI + C + M, two rescue options showed similar efficacy: PPI + B + T + M (78%) and PPI + C + levofloxacin (L) (71%) (P > .05). In third line, after the failure of PPI + C + M and PPI + C + L, PPI + B + T + M was successful in 75% of cases. CONCLUSION In patients allergic to penicillin, a triple combination with PPI + C + M should not be generally recommended as a first-line treatment, while a quadruple regimen with PPI + B + T + M seems to be a better option. As a rescue treatment, this quadruple regimen (if not previously prescribed) or a triple regimen with PPI + C + L could be used but achieved suboptimal (<80%) results.

Combination of Bismuth and Standard Triple Therapy Eradicates Helicobacter pylori Infection in More than 90% of Patients. Clin Gastroenterol Hepatol 2020; 18:89-98. [PMID: 30978536 DOI: 10.1016/j.cgh.2019.03.048] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2017] [Revised: 03/14/2019] [Accepted: 03/24/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Due to the poor eradication rates of standard triple therapy, the addition of bismuth salts has been proposed for first-line eradication of Helicobacter pylori. We assessed the effectiveness and safety of the combination of bismuth and the standard, clarithromycin-containing triple therapy in eradication of H pylori infection, using data from a large multi-center registry. METHODS We performed an interim analysis of data from the European Registry on H pylori Management, a prospective trial registering clinical data and outcomes from infected patients from 27 countries in Europe since 2013. We extracted data on 1141 treatment-naïve patients who received first-line treatment with bismuth salts (240 mg) and a proton pump inhibitor (57% received esomeprazole, 18% received omeprazole, 11% received pantoprazole, and 14% received rabeprazole), amoxicillin (1 g), and clarithromycin (500 mg), all taken twice daily. RESULTS Intention to treat and per-protocol rates of eradication were 88% and 94%, respectively. Intention to treat eradication increased to 93% in patients who received 14-day treatments. Adverse events occurred in 36% of patients; 76% of these events were mild, with a mean duration of 6 days. In multivariate analysis, eradication was associated with treatment compliance (odds ratio [OR], 13.0), a double dose (equivalent to 40 mg omeprazole) of proton pump inhibitor (OR, 4.7), and 14-day duration of treatment (OR, 2.0). CONCLUSIONS In an analysis of data from a large multi-center registry, we found the addition of bismuth to 14-day standard triple therapy with clarithromycin and amoxicillin to eradicate H pylori infection in more than 90% of patients, based on intention to treat analysis, with an acceptable safety profile and level of adherence.

Abstract
Introduction: The Pan-European Registry on Helicobacter pylori management was conceived in 2013 to monitor eradication practices in Europe for 10 years. Aim: To assess the efficacy of different eradication regimens in a single outpatient clinic of gastroenterology. Method: Between 2013 and 2019, 247 patients were registered in a prospective non-interventional study. The infection was diagnosed either by endoscopy, histology, rapid urease test or 13C-urea breath test. As first-line treatment, the patients received either a 7-day triple regimen (any of PPI + amoxicillin + clarithromycin or tinidazole), 10-day modified sequential treatment (PPI + amoxicillin for 5 days + tinidazole and levofloxacin for 5 days), 10-day quadruple concomitant treatment (PPI + amoxicillin + tetracycline or doxycycline + metronidazole or tinidazole) or bismuth-based quadruple treatment. Bismuth or non-bismuth based quadruple or alternative regimens were given as second- or third-line treatment. Results: The eradication rates on per protocol basis were: 82.7% (95% confidence interval: 68.1-97.4) (first-line regimens), 85.2% (75.4-94.9) (sequential treatment), 95.1% (89.6-100) (concomitant treatment) and 82.6% (69.7-95.9) (bismuth-based quadruple regimen). Second-line regimens achieved 65.2% (48.2-83.0) and third-line therapy 54.5% (19.4-86.6), respectively. Conclusion: The first-line concomitant regimen was superior to triple and not significantly better than the sequential or bismuth-based treatment. Second- and third-line regimens achieved largely suboptimal results. Orv Hetil. 2019; 160(47): 1856-1863.

Abstract
AIM European Registry on the management of Helicobacter pylori infection («Hp-EuReg») - 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-EuReg» 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
BACKGROUND Bismuth-containing quadruple therapy has been suggested as first-line and rescue alternative for Helicobacter pylori eradication. Our objective was to perform a meta-analysis evaluating the efficacy and safety of single capsule Pylera® (bismuth, metronidazole, and tetracycline) plus a proton-pump inhibitor (PPI) in any line of treatment. METHODS Studies were selected up to October 2018. Outcomes were eradication and adverse events (AEs) rates pooled using the generic inverse variance method. RESULTS In total, 30 studies (6482 patients) were included in the systematic review. The intention-to-treat (ITT) efficacy was 90% (95% CI: 87%-92%, 21 studies, I2 = 88%) in first-line therapy, 89% (95% CI: 86%-93%, 12 studies, I2 = 78%) in second-line and 82% (95% CI: 78%-87%, nine studies, I2 = 60%) in third-line; with no differences by the type or dosage of PPI used. For metronidazole-resistant infection, the ITT efficacy as first-line therapy was 93% (95% CI: 90%-96%, six studies, I2 = 0%). In second-line therapies where patients had been previously treated with clarithromycin, the ITT efficacy was 90% (95% CI: 87%-93%, 11 studies, I2 = 78%). The overall incidence of AEs was 43% (95% CI: 35%-50%, 24 studies, I2 = 92%) and they were mostly mild. In nearly 3% of the cases, treatment was interrupted due to AEs. CONCLUSIONS A 10-day treatment with Pylera® achieved an effective eradication rate of approximately 90% both in first- and second-line therapy. This applies regardless of the type and dose of the PPI, in patients with clarithromycin- or metronidazole-resistant strains, and in those previously treated with clarithromycin.

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
Background Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in the world affecting over 50% of the world's population. H. pylori is a grade I carcinogen, responsible for the development of 89 % of noncardia gastric cancers. In the present study we analyzed the data for H. pylori eradication treatments in Slovenia. Patients and methods Slovenia is a part of the European Registry on Helicobacter pylori Management from the beginning. In seven medical institutions data for H. pylori eradication treatments was collected for 1774 patients from April 16th 2013 to May 15th 2016. For further modified intention to treat (mITT) analysis 1519 patients were eligible and for per protocol (PP) analysis 1346 patients. Results Patients' dropout was 11.4%. Eradication rate for 7 day triple therapy with proton pump inhibitor (PPI) + Clarithromycin (C) + Amoxicillin (A) was 88.7% PP and 72.0% mITT; for PPI + C + Metronidazole (M) 85.2% PP and 84.4% mITT. Second line 14 day therapy PPI + A + Levofloxacin had 92.3% eradication rate PP and 87.1% mITT. Ten to fourteen day Bismuth quadruple therapy was the therapy in difficult to treat patients. At the end all patients that adhered to prescribed regimens were cured of their H. pylori infection. Conclusions High dropout rate deserves further analysis. Slovenia is still a country with < 15% H. pylori resistance to clarithromycin, triple therapy with PPI plus two antibiotics reaches PP eradication rate > 85%, but mITT eradication rates are suboptimal.

Abstract
BACKGROUND Writing therapy to improve physical or mental health can take many forms. The most researched model of therapeutic writing (TW) is unfacilitated, individual expressive writing (written emotional disclosure). Facilitated writing activities are less widely researched. DATA SOURCES Databases, including MEDLINE, EMBASE, PsycINFO, Linguistics and Language Behaviour Abstracts, Allied and Complementary Medicine Database and Cumulative Index to Nursing and Allied Health Literature, were searched from inception to March 2013 (updated January 2015). REVIEW METHODS Four TW practitioners provided expert advice. Study procedures were conducted by one reviewer and checked by a second. Randomised controlled trials (RCTs) and non-randomised comparative studies were included. Quality was appraised using the Cochrane risk-of-bias tool. Unfacilitated and facilitated TW studies were analysed separately under International Classification of Diseases, Tenth Revision chapter headings. Meta-analyses were performed where possible using RevMan version 5.2.6 (RevMan 2012, The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark). Costs were estimated from a UK NHS perspective and three cost-consequence case studies were prepared. Realist synthesis followed Realist and Meta-narrative Evidence Synthesis: Evolving Standards guidelines. OBJECTIVES To review the clinical effectiveness and cost-effectiveness of TW for people with long-term conditions (LTCs) compared with no writing, or other controls, reporting any relevant clinical outcomes. To conduct a realist synthesis to understand how TW might work, and for whom. RESULTS From 14,658 unique citations, 284 full-text papers were reviewed and 64 studies (59 RCTs) were included in the final effectiveness reviews. Five studies examined facilitated TW; these were extremely heterogeneous with unclear or high risk of bias but suggested that facilitated TW interventions may be beneficial in individual LTCs. Unfacilitated expressive writing was examined in 59 studies of variable or unreported quality. Overall, there was very little or no evidence of any benefit reported in the following conditions (number of studies): human immunodeficiency virus (six); breast cancer (eight); gynaecological and genitourinary cancers (five); mental health (five); asthma (four); psoriasis (three); and chronic pain (four). In inflammatory arthropathies (six) there was a reduction in disease severity [n = 191, standardised mean difference (SMD) -0.61, 95% confidence interval (CI) -0.96 to -0.26] in the short term on meta-analysis of four studies. For all other LTCs there were either no data, or sparse data with no or inconsistent, evidence of benefit. Meta-analyses conducted across all of the LTCs provided no evidence that unfacilitated emotional writing had any effect on depression at short- (n = 1563, SMD -0.06, 95% CI -0.29 to 0.17, substantial heterogeneity) or long-term (n = 778, SMD -0.04 95% CI -0.18 to 0.10, little heterogeneity) follow-up, or on anxiety, physiological or biomarker-based outcomes. One study reported costs, no studies reported cost-effectiveness and 12 studies reported resource use; and meta-analysis suggested reduced medication use but no impact on health centre visits. Estimated costs of intervention were low, but there was insufficient evidence to judge cost-effectiveness. Realist synthesis findings suggested that facilitated TW is a complex intervention and group interaction contributes to the perception of benefit. It was unclear from the available data who might benefit most from facilitated TW. LIMITATION Difficulties with developing realist synthesis programme theory meant that mechanisms operating during TW remain obscure. CONCLUSIONS Overall, there is little evidence to support the therapeutic effectiveness or cost-effectiveness of unfacilitated expressive writing interventions in people with LTCs. Further research focused on facilitated TW in people with LTCs could be informative. STUDY REGISTRATION This study is registered as PROSPERO CRD42012003343.

Abstract
BACKGROUND Non-bismuth quadruple sequential therapy (SEQ) comprising a first induction phase with a dual regimen of amoxicillin and a proton pump inhibitor (PPI) for five days followed by a triple regimen phase with a PPI, clarithromycin and metronidazole for another five days, has been suggested as a new first-line treatment option to replace the standard triple therapy (STT) comprising a proton pump inhibitor (PPI), clarithromycin and amoxicillin, in which eradication proportions have declined to disappointing levels. OBJECTIVES To conduct a meta-analysis of randomised controlled trials (RCTs) comparing the efficacy of a SEQ regimen with STT for the eradication of H. pylori infection, and to compare the incidence of adverse effects associated with both STT and SEQ H. pylori eradication therapies. SEARCH METHODS We conducted bibliographical searches in electronic databases, and handsearched abstracts from Congresses up to April 2015. SELECTION CRITERIA We sought randomised controlled trials (RCTs) comparing 10-day SEQ and STT (of at least seven days) for the eradication of H. pylori. Participants were adults and children diagnosed as positive for H. pylori infection and naïve to H. pylori treatment. DATA COLLECTION AND ANALYSIS We used a pre-piloted, tabular summary to collect demographic and medical information of included study participants as well as therapeutic data and information related to the diagnosis and confirmatory tests.We evaluated the difference in intention-to-treat eradication between SEQ and STT regimens across studies, and assessed sources of the heterogeneity of this risk difference (RD) using subgroup analyses.We evaluated the quality of the evidence following Cochrane standards, and summarised it using GRADE methodology. MAIN RESULTS We included 44 RCTs with a total of 12,284 participants (6042 in SEQ and 6242 in STT). The overall analysis showed that SEQ was significantly more effective than STT (82% vs 75% in the intention-to-treat analysis; RD 0.09, 95% confidence interval (CI) 0.06 to 0.11; P < 0.001, moderate-quality evidence). Results were highly heterogeneous (I² = 75%), and 20 studies did not demonstrate differences between therapies.Reporting by geographic region (RD 0.09, 95% CI 0.06 to 0.12; studies = 44; I² = 75%, based on low-quality evidence) showed that differences between SEQ and STT were greater in Europe (RD 0.16, 95% CI 0.14 to 0.19) when compared to Asia, Africa or South America. European studies also showed a tendency towards better efficacy with SEQ; however, this tendency was reversed in 33% of the Asian studies. Africa reported the closest risk difference (RD 0.14 , 95% 0.07 to 0.22) to Europe among studied regions, but confidence intervals were wider and therefore the quality of the evidence showing SEQ to be superior to STT was reduced for this region.Based on high-quality evidence, subgroup analyses showed that SEQ and STT therapies were equivalent when STT lasted for 14 days. Although, overall, the mean eradication proportion with SEQ was over 80%, we noted a tendency towards a lower average effect with this regimen in the more recent studies (2008 and after); weighted linear regression showed that the efficacies of both regimens evolved differently over the years, having a higher reduction in the efficacy of SEQ (-1.72% yearly) than in STT (-0.9% yearly). In these more recent studies (2008 and after) we were also unable to detect the superiority of SEQ over STT when STT was given for 10 days.Based on very low-quality evidence, subgroup analyses on antibiotic resistance showed that the widest difference in efficacy between SEQ and STT was in the subgroup analysis based on clarithromycin-resistant participants, in which SEQ reached a 75% average efficacy versus 43% with STT.Reporting on adverse events (AEs) (RD 0.00, 95% CI -0.02 to 0.02; participants = 8103; studies = 27; I² = 26%, based on high-quality evidence) showed no significant differences between SEQ and STT (20.4% vs 19.5%, respectively) and results were homogeneous.The quality of the studies was limited due to a lack of systematic reporting of the factors affecting risk of bias. Although randomisation was reported, its methodology (e.g. algorithms, number of blocks) was not specified in several studies. Additionally, the other 'Risk of bias' domains (such as allocation concealment of the sequence randomisation, or blinding during either performance or outcome assessment) were also unreported.However, subgroup analyses as well as sensitivity analyses or funnel plots indicated that treatment outcomes were not influenced by the quality of the included studies. On the other hand, we rated 'length of STT' and AEs for the main outcome as high-quality according to GRADE classification; but we downgraded 'publication date' quality to moderate, and 'geographic region' and 'antibiotic resistance' to low- and very low-quality, respectively. AUTHORS' CONCLUSIONS Our meta-analysis indicates that prior to 2008 SEQ was more effective than STT, especially when STT was given for only seven days. Nevertheless, the apparent advantage of sequential treatment has decreased over time, and more recent studies do not show SEQ to have a higher efficacy versus STT when STT is given for 10 days.Based on the results of this meta-analysis, although SEQ offers an advantage when compared with STT, it cannot be presented as a valid alternative, given that neither SEQ nor STT regimens achieved optimal efficacy ( ≥ 90% eradication rate).

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.

Meta-analysis: esomeprazole or rabeprazole vs. first-generation pump inhibitors in the treatment of Helicobacter pylori infection. Aliment Pharmacol Ther 2012; 36:414-25. [PMID: 22803691 DOI: 10.1111/j.1365-2036.2012.05211.x] [Citation(s) in RCA: 121] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2012] [Revised: 04/05/2012] [Accepted: 06/20/2012] [Indexed: 12/12/2022]
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.
