Abstract
Helicobacter pylori is a gram-negative bacterium that colonizes the stomach of approximately half of the worldwide population, with higher prevalence in densely populated areas like Asia, the Caribbean, Latin America, and Africa. H. pylori infections range from asymptomatic cases to potentially fatal diseases, including peptic ulcers, chronic gastritis, and stomach adenocarcinoma. The management of these conditions has become more difficult due to the rising prevalence of drug-resistant H. pylori infections, which ultimately lead to gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. In 1994, the International Agency for Research on Cancer (IARC) categorized H. pylori as a Group I carcinogen, contributing to approximately 780,000 cancer cases annually. Antibiotic resistance against drugs used to treat H. pylori infections ranges between 15% and 50% worldwide, with Asian countries having exceptionally high rates. This review systematically examines the impacts of H. pylori infection, the increasing prevalence of antibiotic resistance, and the urgent need for accurate diagnosis and precision treatment. The present status of precision treatment strategies and prospective approaches for eradicating infections caused by antibiotic-resistant H. pylori will also be evaluated.

Ji YH, Shi YM, Hei QW, Sun JM, Yang XF, Wu T, Sun DL, Qi YX. Evaluation of guidelines for diagnosis and treatment of Helicobacter pylori infection. Helicobacter 2023; 28:e12937. [PMID: 36408808 DOI: 10.1111/hel.12937] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 10/11/2022] [Accepted: 10/31/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND To systematically evaluate the quality of the guidelines for the diagnosis and treatment of Helicobacter pylori infection and to analyze the differences and reasons for the key recommendations in the guidelines. METHODS Databases and websites were systematically searched to obtain guidelines for the diagnosis and treatment of Helicobacter pylori infection. Four independent reviewers used the Guideline Evaluation Tool (AGREE II) to evaluate the included guidelines. The intraclass correlation coefficient (ICC) and Fleiss' kappa coefficient were used to measure the consistency of evaluation guidelines between guide reviewers. Differences between guidelines and the reasons for the differences were analyzed by comparing the recommendations of different guidelines and the evidence supporting the recommendations. RESULTS A total of 17 guidelines for Helicobacter pylori infection were included in this study. The AGREE II scores of these guidelines were low overall, with 4 of them had a score of over 60%, which indicates that the guidelines are recommended, and 13 of them having a score ranging from 30 to 60%, which indicates that the guidelines are recommended but need to be revised, while no guideline had a score of 30% or less, which indicates that they were not recommended. The analysis of these guidelines found that there were some differences in the main recommendations. Not all guidelines recommend sequential therapy as the recommended therapy. Whether bismuth quadruple therapy should be used as the recommended first-line therapy is unclear. The antibiotic resistance rate is different in different regions. Combined with the local antibiotic sensitivity test, the eradication rate of Helicobacter pylori can be improved. CONCLUSION There are significant differences in the quality of Helicobacter pylori infection guidelines and the key recommendations. Improving the deficiencies of existing guidelines is an effective way to develop high-quality guidelines and make reasonable recommendations for the treatment of Helicobacter pylori infection in the future.

Ten-day concomitant and sequential therapy for Helicobacter pylori effective in region with high antibiotic resistance rates. Indian J Gastroenterol 2022; 41:627-633. [PMID: 36573961 DOI: 10.1007/s12664-022-01272-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 06/07/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Increasing antibiotic-resistant Helicobacter pylori (H. pylori) strains complicate efforts to eradicate infection. In regions with high dual resistance to both clarithromycin and metronidazole, bismuth quadruple therapy is recommended. But, with lack of easy availability of bismuth, the (non-bismuth) concomitant and sequential regimens are used commonly as first-line therapy. Recent reports indicate suboptimal results with sequential therapy in such regions. We aimed to compare the efficacy of concomitant therapy vs. sequential therapy in the eradication of H. pylori in a region with high antibiotic resistance rates, and to compare adherence rates and adverse events with the regimens. METHODS One hundred and twenty-four consecutive H. pylori-infected patients (diagnosed using rapid urease test or urea breath test) were randomized to receive sequential or concomitant therapy for 10 days each. Four weeks after treatment completion, urea breath test was done to confirm eradication of the infection. Cure rates were compared between the two regimens and note was made of adherence rates and adverse events. RESULTS Concomitant therapy showed a statistically non-significant higher cure rate compared to sequential therapy in intention-to-treat (87.1% vs. 81.4%%, p = 0.46) and per-protocol (94.7% vs. 83.9%, p = 0.07) analyses. Both the regimens were well tolerated and showed similar adherence rates (p = 1.00) and incidence of adverse events (p = 0.44). CONCLUSION In a region with high dual resistance, both concomitant and sequential therapy for H. pylori infection achieved eradication rates >80%, but concomitant therapy showed a statistically non-significant higher cure rate, with similar adherence and adverse event profiles.

Abstract
The management and effectiveness of the treatment of Helicobacter pylori infection are heterogeneous worldwide, despite the publication of international consensus conferences and guidelines, which have been widely available for years. The aim of the study was to describe the clinical management and the eradication rates in a region of Southern Europe (Spain). Between 2010 and 2019, we conducted a retrospective analysis of patients with H. pylori infection attended by gastroenterologists in two defined areas of the National Health System in Aragón. We compared the appropriateness of therapies according to guidelines, and described the effectiveness of each treatment. A total of 1644 penicillin non-allergic patients were included. The most prescribed therapy between 2010 and 2013 was the ‘classic’ triple therapy PCA (80%), whereas the ’concomitant’ therapy PCAM was chosen by 90% of the gastroenterologists in 2015. After 2016, the use of the quadruple bismuth-containing therapy in a single capsule (Pylera®) quickly increased, representing almost half of the overall prescriptions in 2019. Throughout the decade, adherence to guidelines was 76.4% and global efficacy was 70.7% (ITT). Triple therapies’ eradication rates were lower than 70% (ITT), whereas eradication rates with quadruple therapies achieved or were over 80% (ITT). In conclusion, despite the use of quadruple therapies and optimized treatments, the effectiveness of H. pylori management in daily clinical practice is far from the target of 90%.

Abstract
Introduction: Helicobacter pylori (H. pylori) colonization is prevalent all over the world, and it is associated with low socioeconomic status, poor hygiene, and overcrowding. Its eradication is important since it is an etiologic agent for gastritis, peptic ulcer, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. Different regimens are available for the eradication of H. pylori and include triple therapy and sequential therapy. Our study aims to compare the efficacy of triple therapy versus sequential therapy in the eradication of H. pylori. Material and methods: This randomized clinical trial was conducted at the Pakistan Institute of Medical Sciences Hospital, Islamabad, from September 2016 to September 2017 after the approval of the institutional review board. A total of 160 patients were enrolled and equally divided into two, group A and group B. A twice-daily dose of amoxicillin 1,000 mg, rabeprazole 20 mg, and clarithromycin 500 mg was given to group A for 10 days, while group B was initially given rabeprazole 20 mg and amoxicillin 1,000 mg two times daily for the first five days (i.e., induction phase), followed by triple therapy that included rabeprazole 20 mg, clarithromycin 500 mg, and metronidazole/tinidazole 500 mg twice daily for the next five days. A negative stool antigen test performed four weeks after the completion of therapy was considered an effective eradication. A proforma was used to collect data that included age, gender, city or province of residence, family income, group (group A or group B), and eradication efficacy. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). Results: A total of 160 patients were included, with mean age and standard deviation of 40.02±24.4 years. The male/female ratio was 1.8:1. Successful eradication of H. pylori achieved in group A was 67.5% (N=54) in comparison to group B, which was 95% (N=76) (p=0.001). Conclusion: Sequential therapy was superior to triple therapy in H. pylori eradication.

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.

Abstract
BACKGROUND AND AIMS To improve Helicobacter pylori (H. pylori) eradication rate, enhanced patient instructions (EPI) such as telephone-based re-education, short-message service, and Wechat have been proposed with conflicting results. The aim of this meta-analysis was to evaluate the effect of EPI on H. pylori eradication. METHODS The PROSPERO registered number of this study is CRD42021278536. PubMed, Embase, and CENTRAL database were searched to identify relevant randomized controlled trials (RCTs) from inception to September 2021. Meta-analysis was performed to estimate the pooled relative risk (RR) with 95% confidence intervals (CI) using a random-effects model. Trial sequential analysis (TSA) was conducted to determine the robustness of the H. pylori eradication rate. RESULTS Nine RCTs were included. Compared with patients receiving only regular instructions, patients received EPI showed significantly higher H. pylori eradication rate (n = 8 RCTs, ITT analysis: RR = 1.20, 95% CI: 1.06-1.35; PP analysis: RR = 1.12, 95% CI:1.02-1.23) and better patient compliance (n = 8 RCTs, RR = 1.23, 95% CI: 1.09-1.39), as well as higher patient satisfaction (n = 3 RCTs, RR = 1.42, 95% CI: 1.14-1.76). However, there were no significant difference between groups in the incidence of total adverse events (n = 6 RCTs, RR = 0.66, 95%CI: 0.40-1.08) and symptom relief rates (n = 2 RCTs, RR = 1.17, 95% CI: 0.89-1.54). The TSA result indicated that the effect was robust. CONCLUSIONS Evidence from our meta-analysis shows that EPI intervention may be a promising strategy to improve H. pylori eradication rate, patient compliance, and patient satisfaction.

Abstract
Sequential therapy (ST) and concomitant therapy (CT) are common first-line treatments for Helicobacter pylori (HP). This study aimed to assess the efficiency and safety of ST and CT in the first-line treatment of HP by comparing their clinical outcomes. Two authors independently searched PubMed, EBSCO, Web of Science and the Cochrane Library for all the relevant articles published before March 2021 to compare the clinical outcomes of HP patients undergoing ST or CT. The primary outcome measures were HP eradication rates and adverse events (AEs). This meta-analysis included 24 articles with 7531 HP patients. CT was better than ST in eradicating HP from per-protocol analysis (PP) (RR=0.96, P<0.001) and modified intent-to-treat analysis (MITT) (RR=0.94, P=0.005). Compared with non-Asia, CT demonstrated more apparent advantages than ST in Asia. CT treated with lansoprazole, pantoprazole and esomeprazole outperformed ST treated with the same PPIs. CT for 10 days and ST for 14 days were the better choices of course of treatment. The incidence rates of AEs were significantly higher in CT than in ST for diarrhoea (RR=0.65, P<0.001), vomiting (RR=0.68, P=0.03), dysgeusia (RR=0.83, P=0.03) and dizziness (RR=0.77, P=0.05). Both ST and CT are safe and effective first-line treatments for HP. Although the AEs were more frequent with CT than ST, CT was superior to ST, especially in Asia. The effect of various PPIs varied in various therapies. The best course of treatment was 10 days for CT and 14 days for ST.

Abstract
The prevalence of Helicobacter pylori infection remains significant worldwide and it depends on many factors: gender, age, socio-economic status, geographic area, diet, and lifestyle. All successful infectious diseases treatments use antibiotic-susceptibility testing, but this strategy is not currently practical for H. pylori and the usual cure rates of H. pylori are lower than other bacterial infections. Actually, there is no treatment that ensures complete eradication of this pathogen. In the context of an alarming increase in resistance to antibiotics (especially to clarithromycin and metronidazole), alternative and complementary options and strategies are taken into consideration. As the success of antibacterial therapy depends not only on the susceptibility to given drugs, but also on the specific doses, formulations, use of adjuvants, treatment duration, and reinfection rates, this review discusses the current therapies for H. pylori treatment along with their advantages and limitations. As an alternative option, this work offers an extensively referenced approach on natural medicines against H. pylori, including the significance of nanotechnology in developing new strategies for treatment of H. pylori infection.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. H. pylori is responsible for substantial gastrointestinal morbidity with a high disease burden. Since the revision of the H. pylori Clinical Practice Guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin based triple therapy. According to a nationwide randomized controlled study by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance to clarithromycin. The clinical practice guidelines for treatment of H. pylori were updated based on evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines were designed to provide clinical evidence for the treatment of H. pylori to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards, and will be revised if more evidence emerges in the future.

Evidence-Based Guidelines for the Treatment of Helicobacter pylori Infection in Korea 2020. Gut Liver 2021; 15:168-195. [PMID: 33468712 PMCID: PMC7960974 DOI: 10.5009/gnl20288] [Citation(s) in RCA: 53] [Impact Index Per Article: 17.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 10/14/2020] [Accepted: 10/20/2020] [Indexed: 01/10/2023] Open
Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. Although the prevalence of H. pylori is gradually decreasing, approximately half of the world's population still becomes infected with this disease. H. pylori is responsible for substantial gastrointestinal morbidity worldwide, with a high disease burden. It is the most common cause of gastric and duodenal ulcers and gastric cancer. Since the revision of the H. pylori clinical practice guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin-based triple therapy for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance, especially from clarithromycin. The clinical practice guidelines for the treatment of H. pylori were updated according to evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after an expert consensus on three recommendations regarding the indication for treatment and eight recommendations for the treatment itself. These guidelines were designed to provide clinical evidence for the treatment (including primary care treatment) of H. pylori infection to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards and will be revised if more evidence emerges in the future.

Abstract
The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump inhibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10,267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effectiveness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. “Optimized” H. pylori therapies achieve over 90% success in Spain.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases worldwide. Although its incidence is gradually decreasing, about half of the world's population still get infected. H. pylori infection is responsible for substantial gastrointestinal morbidity worldwide. It is the most common cause of gastric and duodenal ulcers as well as gastric cancer. Since the revision of the H. pylori Clinical Practice Guidelines in 2013, the eradication rate of H. pylori has gradually decreased with the use of classical triple therapy, wherein amoxicillin, clarithromycin, and proton pump inhibitors are administered, for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was due to increased antimicrobial resistance induced by the use of antibiotics, especially clarithromycin. The update of clinical practice guideline for treatment of H. pylori was developed based on evidence-based medicine by conducting a meta-analysis. The draft recommendations were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines are designed to provide patients, nurses, medical school students, policymakers, and clinicians with clinical evidence to guide primary care and treatment of H. pylori infection. These may differ from current medical insurance standards and will be revised further, if necessary, based on research-based evidence.

J Clin Med 2020; 9:jcm9082410. [PMID: 32731455 PMCID: PMC7464342 DOI: 10.3390/jcm9082410] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 07/21/2020] [Accepted: 07/23/2020] [Indexed: 02/07/2023] Open
Abstract
Background: The current cure rates with triple therapy combining a proton-pump inhibitor, amoxicillin and clarithromycin are unacceptably low. Aims: To evaluate the efficacy of a 14-day concomitant therapy as an empirical first-line treatment for curing Helicobacter pylori (Hp) infection in primary care. Methods: Patients from six primary care centers in Catalonia -Spain- were included consecutively. Hp status pre and post treatment was assessed according to local clinical practice protocol. A 14-day concomitant therapy (amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg plus omeprazole 20 mg, all drugs administered twice daily) was prescribed. Adherence to therapy and adverse events were assessed by personal interview. Results: 112 patients were enrolled. Mean age was 46.7 ± 16.1 years. Main indication for treatment was non-investigated dyspepsia (83%). Hp eradication was achieved in 100 of the 112 patients. Eradication rates were 89.3% (95% CI: 81.7–94.1) by intention-to-treat (ITT) analysis and 91.7% (95% CI; 84.6–95.9) per protocol (PP). No major side effects were reported; 104 (92.8%) patients complete the treatment. Forty-seven patients (42%) complained of mild side effects (metallic taste, nausea). Low adherence to treatment (p = 0.004) and significant adverse events (p = 0.004) were the variables associated with treatment failure. Conclusions: In primary care, a 14-day concomitant therapy is highly effective and well tolerated.

Kim SY, Chung JW. Best Helicobacter pylori Eradication Strategy in the Era of Antibiotic Resistance. Antibiotics (Basel) 2020; 9:antibiotics9080436.

Abstract
Antibiotic resistance is the major reason for Helicobacter pylori treatment failure, and the increasing frequency of antibiotic resistance is a challenge for clinicians. Resistance to clarithromycin and metronidazole is a particular problem. The standard triple therapy (proton pump inhibitor, amoxicillin, and clarithromycin) is no longer appropriate as the first-line treatment in most areas. Recent guidelines for the treatment of H. pylori infection recommend a quadruple regimen (bismuth or non-bismuth) as the first-line therapy. This treatment strategy is effective for areas with high resistance to clarithromycin or metronidazole, but the resistance rate inevitably increases as a result of prolonged therapy with multiple antibiotics. Novel potassium-competitive acid blocker-based therapy may be effective, but the data are limited. Tailored therapy based on antimicrobial susceptibility test results is ideal. This review discussed the current important regimens for H. pylori treatment and the optimum H. pylori eradication strategy.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is one of the most common bacterial infections worldwide, which is associated with peptic ulcer disease and gastric cancer. In this study, we compared the efficacy of 10-day versus 12-day concomitant therapy as the first-line treatment for H. pylori eradication in Iran. METHODS 218 patients with peptic ulcer disease and naïve H. pylori infection, were randomly divided into two groups to receive either 10-day or 12-day concomitant regimens, composed of pantoprazole 40 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg, all given twice daily. Eight weeks after treatment, H. pylori eradication was assessed by 14C- urea breath test. The trial was registered in the Iranian Registry of Clinical Trials (code: IRCT20170521034070N2). RESULTS 212 patients completed the study. According to the intention to treat analysis, the eradication rates were 83.6% (95% CI: 76.6-90.5) and 88.8% (95% CI: 82.8-94.7) in 10-day and 12-day concomitant therapy groups, respectively (p = 0.24). Per-protocol eradication rates were 85.9% (95% CI: 79.3–92.4) and 92.6% (95% CI: 87.6–97.5), respectively (p = 0.19). The rates of severe side effects were not statistically different between the two groups (3.6% vs. 8.1%; p = 0.428). CONCLUSION 12-day concomitant therapy could achieve ideal eradication rates by both intention to treat and perprotocol analyses. In order to reduce the cost of drugs and the rate of adverse effects of therapy, among 10-day and 12day regimens, 12-day concomitant therapy seems to be a good alternative to 14-day concomitant therapy that has been suggested by international guidelines.

Abstract
OBJECTIVE To date, no randomised trials have compared the efficacy of vonoprazan and amoxicillin dual therapy with other standard regimens for Helicobacter pylori treatment. This study aimed to investigate the efficacy of the 7-day vonoprazan and low-dose amoxicillin dual therapy as a first-line H. pylori treatment, and compared this with vonoprazan-based triple therapy. DESIGN This prospective, randomised clinical trial was performed at seven Japanese institutions. Patients with H. pylori-positive culture test and naive to treatment were randomly assigned in a 1:1 ratio to either VA-dual therapy (vonoprazan 20 mg+amoxicillin 750 mg twice/day) or VAC-triple therapy (vonoprazan 20 mg+amoxicillin 750 mg+clarithromycin 200 mg twice/day) for 7 days, with stratification by age, sex, H. pylori antimicrobial resistance and institution. Eradication success was evaluated by 13C-urea breath test at least 4 weeks after treatment. RESULTS Between October 2018 and June 2019, 629 subjects were screened and 335 were randomised. The eradication rates of VA-dual and VAC-triple therapies were 84.5% and 89.2% (p=0.203) by intention-to-treat analysis, respectively, and 87.1% and 90.2% (p=0.372) by per-protocol analysis, respectively. VA-dual was non-inferior to VAC-triple in the per-protocol analysis. The eradication rates in strains resistant to clarithromycin for VA-dual were significantly higher than those for VAC-triple (92.3% vs 76.2%; p=0.048). The incidence of adverse events was equal between groups. CONCLUSION The 7-day vonoprazan and low-dose amoxicillin dual therapy provided acceptable H. pylori eradication rates and a similar effect to vonoprazan-based triple therapy in regions with high clarithromycin resistance.

Abstract
INTRODUCTION Dyspepsia and Helicobacter pylori are two of the most relevant digestive conditions in primary care. Several consensuses on the subject have been published, but the assimilation/implementation of these guidelines is uncertain. AIMS AND METHODS To evaluate the attitudes, perceptions, limitations, and adherence to recommendations of Spanish primary care physicians using an open online survey. Responses were anonymously codified. Estimated margin of error was 3.4%. Responses were weighted by province, gender, age, and type of practice. Survey was performed using the AEG-REDCap platform. RESULTS A total of 1445 responses, received between December 2017 and April 2018, were analyzed. Women represented 54%, and the average age was 48 years; 59% were from urban context, 20% from semi-urban, and 21% from rural; 93% provided public practice. Over 40% had read at least one Maastricht consensus (24% Maastricht V), and 34% had attended a course related to H. pylori. 16% reported no direct access to any validated diagnostic method, only 44% to urea breath test, and 33% did not systematically refer to eradication confirmation test. The first-line treatment of choice was standard triple therapy in 56%, followed by concomitant therapy (28%). Only 20% of physicians had optimal adherence to recommendations. CONCLUSION Even though some improvements from guidelines have been partially incorporated, the level of penetration of recommendations is still poor and delayed. To provide optimal primary care, the barriers for implementation, access to diagnostic tests and to continuous medical education, should be removed. Rigorous dissemination, implementation, and evaluation programs are desired in future consensuses.

Abstract
INTRODUCTION Resistance to clarithromycin and fluoroquinolones is increasing in many countries. We aimed to assess the efficacy of a tailored PCR-guided triple therapy versus an empirical triple therapy in the treatment of H. pylori infection. PATIENTS AND METHODS French multicenter prospective open-label randomized study to assess H. pylori and resistance to clarithromycin and levofloxacin with GenoType HelicoDR® test. Patients of the control group were treated with empirical therapy of proton pump inhibitor (PPI), amoxicillin, and clarithromycin for 7 days. Patients of the experimental group with clarithromycin-susceptible strains, clarithromycin-resistant/levofloxacin-susceptible strains, and with clarithromycin-resistant/levofloxacin-resistant strains received tailored therapy of PPI, amoxicillin, and clarithromycin for 7 days, PPI, amoxicillin, and levofloxacin for 10 days, and PPI, amoxicillin, and metronidazole for 14 days, respectively. H. pylori eradication was assessed by 13C urea breath test at least 28 days after the end of treatment. RESULTS We included 526 patients: 260 (49.4%) were randomly assigned to empirical triple therapy and 266 (50.6%) to tailored therapy. Clarithromycin and levofloxacin resistances were 23.3% and 12.8%, respectively. Follow-up urea breath test was available for 415 (78.9%) patients. Tailored therapy was superior to empirical therapy in terms of eradication (85.5% vs. 73.1%, RR=1.85, 95%CI [1.25-2.78], p=0.003). Findings were consistent in the susceptibility analysis using multiple imputation (RR=1.61, 95%CI [1.14-2.27], P=0.003) and per-protocol analysis (RR=1.89, 95%CI [0.25-2.78], p=0.003). CONCLUSION In a country with a high level of clarithromycin resistance, tailored PCR-guided therapy was superior to empirical triple therapy for H. pylori eradication (https://www.ClinicalTrials.gov: NCT01168063).

Twice daily short-message-based re-education could improve Helicobacter pylori eradication rate in young population: A prospective randomized controlled study. Helicobacter 2019; 24:e12569. [PMID: 30848868 DOI: 10.1111/hel.12569] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2018] [Revised: 12/06/2018] [Accepted: 12/12/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND To investigate the effects of twice daily short-message-based re-education (SMRE) before taking medicine for Helicobacter pylori (H pylori) eradication. MATERIALS AND METHODS Treatment-naive patients with H pylori infection were prescribed 14-day quadruple regimen consisting of lansoprazole 30 mg, colloidal bismuth pectin 200 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily. Patients were randomly allocated to SMRE group or control group. Patients in control group received oral and written instructions at outpatient clinic. In contrast, patients in the SMRE group received extra short messages including dosage and time of administration twice daily. Successful H pylori eradication was assessed using the 13 C-urea breath test 6 weeks after treatment. The compliance, adverse events, and patient satisfaction were also analyzed. RESULTS A total of 310 patients were enrolled in the intention-to-treat (ITT) and 283 in the per-protocol (PP) analysis. For young patients, the eradication rates were significantly higher in SMRE group than those in control group in PP analysis (88.6% vs 71.2%, P = 0.036), while for patients of all age groups, the eradication rate improvements were not statistically significant. The eradication rates in SMRE group and control group were 74.2% and 67.7% (P = 0.211) in ITT analysis and 82.1% and 73.4% (P = 0.078) in PP analysis, respectively. The compliance in SMRE group was significantly better than that in control group (84.8% vs 72.8%, P = 0.011). CONCLUSIONS Twice daily SMRE could improve the eradication rate in young population, as well as the compliance with treatment during H pylori eradication.

Abstract
BACKGROUND Concomitant quadruple (CQT) or bismuth-containing quadruple therapy (BQT) is recommended as first-line treatment for Helicobacter pylori infection depending on antibiotic resistance. AIM To compare the efficacy, safety, and compliance of CQT and BQT as first-line therapy for H. pylori eradication in real clinical practice in an area of high resistance to clarithromycin. METHODS A prospective, open, comparative cross-sectional study including dyspeptic patients >18 years with H. pylori infection and with no previous eradication treatment was performed. CQT (omeprazole 20 mg + clarithromycin 500 mg + amoxicillin 1 g + metronidazole 500 mg, all given twice daily, for 14 days) or BQT (omeprazole 20 mg twice daily + 3 capsules of Pylera® 4 times a day, for 10 days) was prescribed at the discretion of the prescribing physician. Eradication was tested by 13 C-urea breath test. Efficacy was assessed by intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS One hundred and four consecutive patients were included (64.4% female, age 52.9 years). Fifty patients received CQT and 54 BQT. Eradication rate was similar with both therapies at the PP (CQT 97.9%, 95% CI: 93.9-100 vs BQT 96.2%, 95% CI: 90.9-100, P = 0.605) and ITT analyses (CQT 98.0%, 95% CI: 94-100 vs BQT 94.4%, 95% CI: 88.1-100, P = 0.346). The rate of adverse events was also similar with CQT (56%) and BQT (46.3%). One patient in each group discontinued the treatment due to significant adverse events. CONCLUSION The use of CQT and BQT as first-line treatment against H. pylori is similarly effective and safe strategy in an area of high clarithromycin resistance.

Abstract
Helicobacter pylori treatment may be viewed as an uncertain situation, where current knowledge is insufficient to provide evidence-based recommendations for all possible scenarios. Evidence suggests that, under uncertainty conditions, a few simple rules of thumb tend to work better than complex algorithms. Overall, five evidence-based rules of thumb are suggested: (1) Use four drugs; (2) Use maximal acid inhibition; (3) Treat for 2 weeks; (4) Do not repeat antibiotics after treatment failure; and (5) If your treatment works locally, keep using it. These simple rules of thumb may help the reader to select the best alternative for a given patient, choosing between the heterogeneous recommendations provided by the many different consensus conferences on H. pylori treatment recently published.

Abstract
BACKGROUND There is some evidence that prior use of macrolide antibiotics is a useful predictor of the likelihood of standard triple therapy failure in Helicobacter pylori eradication. In this study, we have evaluated whether previous intake of macrolides correlates with failure to eradicate H. pylori using two different first-line clarithromycin-containing regimens. MATERIALS AND METHODS Retrospective study of 212 patients with H. pylori infection treated with one of two first-line clarithromycin-containing regimens: 108 patients treated with triple therapy for 10 days and 104 patients treated with concomitant therapy for 10 days. The intake of macrolides (clarithromycin, azithromycin, and other macrolides) prior to the eradication therapy was obtained from the electronic medical record, which contains information regarding all the medication prescribed to the patients since the year 2004. RESULTS One hundred of 212 patients (47.2%) had received at least one treatment with macrolides during the years prior to the eradication therapy. H. pylori eradication rates were significantly lower in patients with previous use compared to patients without previous use of macrolides, both with triple therapy (60.8% vs 92.9%; P < .0001) and with concomitant therapy (85.7% vs 98.2%; P = .024). CONCLUSIONS Previous use of macrolides correlates with a low H. pylori eradication rate with triple and concomitant clarithromycin-containing regimens. In addition, our study shows that in patients without previous use of macrolides, triple therapy achieves per-protocol eradication rates over 90%.

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 AND AIMS Quadruple therapy is recommended as second-line treatment for Helicobacter pylori eradication failure. However, high cost, multiple side effects, and low adherence rates are major drawbacks to its routine use. Our aim was to compare the efficacy and safety of sequential versus quadruple regimens as second line treatment for persistent Helicobacter pylori infection. METHODS Prospective, randomized, open label trial was conducted at a large academic, tertiary care center in Israel. Patients who previously failed a standard triple treatment eradication course were randomly assigned (1:1) to receive a 10-day sequential therapy course, or a 14-day quadruple regimen. Compliance and adverse events were evaluated by telephone questionnaires. The primary endpoint for analysis was the rate of Helicobacter pylori eradication as defined by either a negative 13C-urea breath-test, or stool antigen test, 4-16 weeks after treatment assessed under the non-inferiority hypothesis. The trial was terminated prematurely due to low recruitment rates. See S1 Checklist for CONSORT checklist. RESULTS One hundred and one patients were randomized. Per modified intention-to-treat analysis, eradication rate was 49% in the sequential versus 42.5% in the quadruple regimen group (p-value for non-inferiority 0.02). Forty-two (84.0%) versus 33 (64.7%) patients completed treatment in the sequential and quadruple groups respectively (p 0.027). Gastrointestinal side effects were more common in the quadruple regimen group. CONCLUSION Sequential treatment when used as a second line regimen, was non-inferior to the standard of care quadruple regimen in achieving Helicobacter pylori eradication, and was associated with better compliance and fewer adverse effects. Both treatment protocols failed to show an adequate eradication rate in the population of Southern Israel. TRIAL REGISTRATION ClinicalTrials.gov NCT01481844.

Abstract
Background/Aims Hybrid therapy was successful in eradicating Helicobacter pylori (H. pylori) according to previous reports. However, to the best of our knowledge, there have only been a few studies evaluating the optimal choice after hybrid failure. Hence, we aimed to evaluate the efficacy of moxifloxacin-containing triple therapy after hybrid therapy failure in H. pylori eradication. Methods Between January 2013 and March 2016, we retrospectively reviewed patients who underwent failed hybrid therapy, as first line treatment, in eradicating H. pylori (rabeprazole and amoxicillin b.i.d for 14 days, in addition to clarithromycin and metronidazole b.i.d for final 7 days). Then, we investigated the eradication rates of moxifloxacin-containing triple therapy (rabeprazole, amoxicillin b.i.d and moxifloxacin qd) as the second line of treatment. Intention-to-treat (ITT) and per-protocol (PP) analyses were used to determine the eradication rate. We evaluated the status of H. pylori by using 13C-urea breath test 6 weeks after the final treatment. Moreover, compliance and adverse effects of each patient were analyzed. Results Among those who failed the initial hybrid therapy, 11 patients received moxifloxacin-containing triple therapy. The overall eradication rates, as determined by ITT and PP, were 72.7% (n=8/11) and 80% (n=8/10), respectively. The compliance rate was 100%, and there were no serious adverse effects. Conclusions Moxifloxacin-containing triple therapy can be used as a second line therapy in case of hybrid therapy failure. A large scale study is necessary to confirm the findings of this study and establish clinical evidence.

Abstract
Helicobacter pylori (H. pylori) treatment remains a challenge for the clinician, as no available therapy is able to cure the infection in all treated patients. In the last two decades, several antibiotic combinations have been proposed, including triple therapies, bismuth-free therapies (sequential, concomitant, hybrid regimens), and bismuth-based quadruple therapy. Some national and international guidelines on H. pylori management have recently been updated, recommending or discouraging the use of each of these therapeutic approaches, based mainly on the presumed pattern of primary antibiotic resistance in different geographic areas. We examined the recommendations on first-line therapies in the most recently updated guidelines worldwide, taking into account other data affecting the efficacy of a therapy regimen beyond the primary resistance pattern. Although several guidelines highlighted that the results achieved by an eradication therapy are population-specific and not directly transferable, it emerged that some therapy regimens are recommended or discouraged with no mention of the vital need for national data.

Abstract
The microbiota within humans maintains homeostasis and plays important roles in human health. However, some situations such as the use of antibiotics may disrupt the microbiota balance and result in a series of adverse effects. This study aimed to investigate the effects of a commonly used anti-Helicobacter pylori concomitant therapy on the composition of the gut and throat microbiota and any antibiotic resistance that may develop. In addition to the standard regimen, two different supplementary probiotic regimens that both used Saccharomyces boulardii were included. Microbiological culture-based techniques were used to analyse the microbiota composition and antibiotic resistance. Our results showed marked quantitative and qualitative alterations in both the gut and throat microbiota after treatment with not only the standard concomitant therapy but also with either supplementary probiotic regimen. Nevertheless, most of the changes in the gut microbiota (except for yeast and Bacteroides spp. counts) reverted by Day 71, whereas the alterations in the throat microbiota appeared to persist. Patients treated with the eradication therapy in the absence of probiotic supplementation experienced the most pronounced disturbances in the throat microbiota, whereas changes in the throat microbiota appeared to stabilize in the groups that received probiotic supplementation. We also detected higher antibiotic resistance rates for Enterobacteriaceae, Enterococcus spp. and Bacteroides spp. after treatment with the eradication therapy. Co-administration of probiotics is likely to be more effective than post-antibiotic supplementation, and although some beneficial effects were observed, the probiotic combination did not exert significant effects on the unbalanced commensal gut and throat microbiota composition.

Abstract
BACKGROUND AND AIM Whether concomitant therapy is superior to sequential therapy (ST) as first-line therapy of Helicobacter pylori in areas with high clarithromycin resistance remains controversial. The aim of this study was to compare the efficacy and tolerability of 10- or 14-day ST with 10- or 14-day concomitant therapy (CT). METHODS This was a prospective randomized study comparing 10- or 14-day ST with 10- or 14-day CT. The ST-10 and ST-14 groups received pantoprazole 40 mg and amoxicillin 1 g twice a day for the first 5 and 7 days followed by pantoprazole 40 mg, clarithromycin 500 mg, and metronidazole 500 mg twice a day for the remaining 5 and 7 days, respectively. The CT-10 and CT-14 groups received pantoprazole 40 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg twice daily for 10 and 14 days, respectively. RESULTS Three hundred forty-one patients were randomly allocated to the four groups. The modified intention-to-treat eradication rates of ST-10, ST-14, CT-10, and CT-14 were 91.7%, 91.2%, 94.2%, and 98.5%, respectively. The corresponding per protocol eradication rates were 91.4%, 91.0%, 95.6%, and 98.5%. There was no difference in compliance and adverse events in the four groups. Eradication rates increased sequentially with statistical significance in the following order: ST-10, ST-14, CT-10, and CT-14 (P = 0.044). CONCLUSIONS All four regimens achieved eradication rates >90% in per protocol analyses in a country with high clarithromycin resistance. There was no difference in tolerability among the four regimens.

Abstract
BACKGROUND The aim of the present open-label, randomized control trial was to determine the clinical efficacy and safety of two 1-week bismuth-containing quadruple regimens and 1 levofloxacin-based triple regimen for the eradication of Helicobacter pylori infection in treatment-naive patients. The influence of susceptibility and host CYP2C19 polymorphisms on the efficacy was also evaluated. METHODS Eligible patients were randomly to receive esomeprazole and colloidal bismuth pectin along with clarithromycin and amoxicillin (EBCA), esomeprazole and colloidal bismuth pectin along with levofloxacin and amoxicillin (EBLA), or esomeprazole along levofloxacin and amoxicillin (ELA) for 1 week. The primary outcome was the eradication rate in the intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS Overall, 270 patients were randomized. The eradication rates in the above 3 groups were 80.25%, 89.66%, and 81.93% in PP analysis and 72.22%, 86.66%, and 75.56% in ITT analysis, respectively. The eradication rate of EBLA was significantly higher than that of EBCA (P = 0.016) in ITT analysis. No significant differences were found among these groups in terms of adverse effects and compliance. The efficacy was significantly affected by levofloxacin resistance for EBLA (P = 0.01) and ELA (P = 0.04), but not by polymorphisms of CYP2C19 gene for any of the 3 groups. CONCLUSION All 1-week bismuth-containing quadruple therapies and levofloxacin-based triple therapy can obtain an acceptable eradication rate, and levofloxacin-based quadruple regimen exhibits the highest eradication rate. The antibiotic resistant rate of levofloxacin was associated with the eradication rate.

Abstract
Important progress has been made in the management of Helicobacter pylori infection and in this fifth edition of the Maastricht Consensus Report, key aspects related to the clinical role of H. pylori were re-evaluated in 2015. In the Maastricht V/Florence Consensus Conference, 43 experts from 24 countries examined new data related to H. pylori in five subdivided workshops: (1) Indications/Associations, (2) Diagnosis, (3) Treatment, (4) Prevention/Public Health, (5) H. pylori and the Gastric Microbiota. The results of the individual workshops were presented to a final consensus voting that included all participants. Recommendations are provided on the basis of the best available evidence and relevance to the management of H. pylori infection in the various clinical scenarios.

Optimal First-Line Treatment for Helicobacter pylori Infection: Recent Strategies. Gastroenterol Res Pract 2016; 2016:9086581.

Abstract
A new treatment strategy is needed, as the efficacy of triple therapy containing clarithromycin—the current standard treatment for Helicobacter pylori infection—is declining. Increasing antibiotic resistance of H. pylori is the most significant factor contributing to eradication failure. Thus, selecting the most appropriate regimen depending on resistance is optimal, but identifying resistance to specific antibiotics is clinically challenging. In a region suspected to have high clarithromycin resistance, bismuth quadruple therapy and so-called nonbismuth quadruple therapies (sequential, concomitant, and sequential-concomitant hybrid) are some first-line regimen options. However, more research is needed regarding appropriate second-line treatments after first-line treatment failure. Tailored therapy, which is based on antibiotic sensitivity testing, would be optimal but has several limitations for clinical use, and an alternative technique is required. A novel potassium-competitive acid blocker-based eradication regimen could be a valuable eradication option in the near future.

Abstract
We read with interest the recent meta-analysis by Lin et al who evaluated the effectiveness of concomitant regimen for Helicobacter pylori (H. pylori) in Chinese regions. They found that 7-d concomitant regimen is undoubtedly superior to 7-d triple therapy (91.2% vs 77.9%, P < 0.0001). However, it is a common belief that a triple therapy lasting 7 d should be definitively removed from the clinical practice for its ineffectiveness. Only its prolongation to 14 d may give satisfactory success rate. Thus, the assessment of an old and outdated treatment versus a more recent and successful one does not seem to bring novel and useful information. Moreover, a 7-d duration has not been ascertained for concomitant regimen, as main guidelines recommend a 10-d schedule for this scheme. Therefore, only studies comparing 10-d concomitant versus 14-d triple seem to be appropriate according to current Guidelines and would clarify which regimen is the most suitable worldwide. Additionally, in this meta-analysis concomitant and sequential therapy showed similar performances, despite it is common opinion that sequential is more prone than concomitant therapy to fail when metronidazole resistance occurs, and China is characterized by high rate of resistance to this antibiotic. None of the included studies evaluated a priori antibiotic resistances, and the lack of this detail hampers the unveiling of this apparent contradiction. In conclusion, the lack of the evaluation of the quality of included trials as well as their high heterogeneity constitute a burdensome limit to draw solid conclusions in this meta-analysis. On the bases of these considerations and the low number of examined trials, we believe that further studies and the knowledge of antibiotic resistances will support with high quality evidence which is the best regimen and its optimal duration.

Abstract
OBJECTIVE The objective of this study is to compare, in Greece, a region with >20% local resistance to clarithromycin, the efficacy rates of the concomitant versus the sequential H. pylori eradication therapy. MATERIALS AND METHODS Our prospective randomized study included 364 patients with newly diagnosed H. pylori infection, randomized to receive a 10-day concomitant or 10-day sequential therapy. Treatment outcome was assessed by C(13)-urea breath test at least 4 weeks after therapy. Intention to treat (ITT) and per protocol (PP) analysis of the eradication rates were performed. Secondary end points included patient compliance and safety. RESULTS The concomitant therapy group achieved statistically significant higher eradication rates when compared with the sequential treatment group, both in the ITT and in the PP analysis (84.6% versus 70.9%, p = 0.002, and 90.6% versus 78.1%, p = 0.001, respectively), after adjusting for age, gender, smoking status, and the presence or not of ulcer and/or non-ulcer dyspepsia. Both groups displayed excellent compliance rates (99.5% for the concomitant therapy group and 96.2% for the sequential therapy group, p = 0.067). Regarding treatment safety, major adverse events that led to the discontinuation of both regimens were few, with no statistical difference between the two groups (7.0% for the concomitant therapy group and 2.9% for the sequential therapy group). CONCLUSIONS Concomitant therapy led to statistically significant higher eradication rates over sequential therapy. Both therapies showed excellent compliance and an acceptable safety profile. The 10-day quadruple concomitant scheme should be the adopted for first-line H. pylori eradication in Greece.

Abstract
BACKGROUND Currently only a few studies compare sequential and concomitant non-bismuth Helicobacter pylori therapies referring to high antibiotic resistance populations. MATERIALS AND METHODS This multicenter prospective randomized clinical trial included 353 H. pylori positive, treatment naïve, patients. All patients had positive CLO-test and/or histology and culture. They received sequential (esomeprazole 40mg, amoxicillin 1g/bid for 5days, followed by 5days of esomeprazole 40mg, clarithromycin 500mg and metronidazole 500mg bid), or concomitant treatment (all drugs taken concomitantly bid for 10days). Eradication was confirmed by (13)C-urea breath test or histology 4-6weeks after treatment. Adverse events and adherence were evaluated. RESULTS Allocated to concomitant were 175 (72F/103M, mean 52.3years, 38.3% smokers, 25.7% ulcer disease) and 178 (87F/91M, mean 52years, 31% smokers, 19.1% ulcer disease) patients to sequential treatment. There were 303/353 (85.8%) positive cultures, with the following resistances: 34% metronidazole, 27.7% clarithromycin, and 7.9% dual. Eradication rates were, respectively, 89.1% (156/175) vs. 78.7% (140/178) by intention to treat (p=0.01, 95% CI=2.7-18) and 93.4%(156/167) vs. 82.8% (140/169) per protocol (p=0.004, 95% CI=3.6-17.6). Overall, adherence was (98.9%, 95% CI=97-100). Eradication rates according to resistance were the following: dual susceptible strains 67/69 (97.1%), 62/67 (92%) (p=0.4), metronidazole single resistant 38/39 (97.4%), 31/39 (79.5%) (p=0.03, 95% CI=3.5-33), clarithromycin single resistant 25/28 (89.3%), 26/31 (83.9%) (p=0.8), and dual resistant 9/12 (75%), 4/11 (36.4%) (p=0.1) for concomitant and sequential regimens, respectively. Side effects were comparable among regimens, except from diarrhea being more frequent among patients treated with concomitant treatment. CONCLUSIONS Concomitant treatment eradication rate overcomes 90% per protocol and has a significant advantage over sequential therapy. This is probably due to its better efficacy on metronidazole resistant strains. Both regimens were well tolerated and safe.

Abstract
BACKGROUND AND OBJECTIVE In a previous study we found that the classical triple therapy for Helicobacter pylori (H. pylori) had low efficacy (under 70%) in our area. After this finding, in mid 2012 quadruple concomitant therapy started to be prescribed in our hospital. The aim of the present study is to compare the efficacy of classical triple therapy and quadruple concomitant therapy without bismuth. MATERIAL AND METHODS Observational retrospective study of prescribed treatments between 1st January 2012 and 5th May 2014 and their efficacy. RESULTS During the study period 510 patients were prescribed a first line therapy; in 179 cases (35,1%) the combination amoxiciline+clarithromicine+PPI was prescribed during 7-14 days, and 298 patients (58,4%) were treated with amoxicillin+clarithromycin+metronidazole+PPI for 10 days. The quadruple concomitant therapy had a higher efficacy than the classical triple therapy, both in an "intention to treat" (84.8% vs. 65.7%, P=.001) and "per protocol" (86.9% vs. 67.2%, P=.001) analysis. Triple therapy had a higher efficacy when it was prescribed for 10 days compared to 7 days (77.9% vs. 56.5%, P=.005 per "intention to treat" and 77.9% vs. 58.5%, P=.011 "per protocol"). When quadruple concomitant therapy was compared with classical triple therapy prescribed over 10 days no significant differences were found. CONCLUSIONS In our setting, cuadruple concomitant therapy without bismuth has a high efficacy as first line therapy for H. pylori eradication, with much better results than classical triple therapy in the way that it is most widely prescribed (short courses of 7-day with a single dose of omeprazole).

Abstract
AIM: To evaluate the applicability of nonbismuth concomitant quadruple therapy for Helicobacter pylori (H. pylori) eradication in Chinese regions.
METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the efficacy of nonbismuth concomitant quadruple therapy between sequential therapy or triple therapy for H. pylori eradication in Chinese regions. The defined Chinese regions include China, Hong Kong, Taiwan, and Singapore. The primary outcome was the H. pylori eradication rate; the secondary outcome was the compliance with therapy. The PubMed, Embase, Scopus, and Cochrane databases were searched for studies published in the period up to March 2016 with no language restriction.
RESULTS: We reviewed six randomized controlled trials and 1616 patients. In 3 trials comparing concomitant quadruple therapy with triple therapy, the H. pylori eradication rate was significantly higher for 7-d nonbismuth concomitant quadruple therapy than for 7-d triple therapy (91.2% vs 77.9%, risk ratio = 1.17, 95%CI: 1.09-1.25). In 3 trials comparing quadruple therapy with sequential therapy, the eradication rate was not significant between groups (86.9% vs 86.0%). However, higher compliance was achieved with concomitant therapy than with sequential therapy.
CONCLUSION: The H. pylori eradication rate was higher for nonbismuth concomitant quadruple therapy than for triple therapy. Moreover, higher compliance was achieved with nonbismuth concomitant quadruple therapy than with sequential therapy. Thus, nonbismuth concomitant quadruple therapy should be the first-line treatment in Chinese regions.

IV Spanish Consensus Conference on Helicobacter pylori infection treatment. GASTROENTEROLOGIA Y HEPATOLOGIA 2016; 39:697-721. [PMID: 27342080 DOI: 10.1016/j.gastrohep.2016.05.003] [Citation(s) in RCA: 57] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Revised: 05/18/2016] [Accepted: 05/19/2016] [Indexed: 02/06/2023]
Abstract
Helicobacter pylori approximately infect 50% of Spanish population and causes chronic gastritis, peptic ulcer and gastric cancer. Until now, three consensus meetings on H.pylori infection had been performed in Spain (the last in 2012). The changes in the treatment schemes, and the increasing available evidence, have justified organizing the IVSpanish Consensus Conference (March 2016), focused on the treatment of this infection. Nineteen experts participated, who performed a systematic review of the scientific evidence and developed a series of recommendation that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. As starting point, this consensus increased the minimum acceptable efficacy of recommended treatments that should reach, or preferably surpass, the 90% cure rate when prescribed empirically. Therefore, only quadruple therapies (with or without bismuth), and generally lasting 14 days, are recommended both for first and second line treatments. Non-bismuth quadruple concomitant regimen, including a proton pump inhibitor, clarithromycin, amoxicillin and metronidazole, is recommended as first line. In the present consensus, other first line alternatives and rescue treatments are also reviewed and recommended.

Abstract
OBJECTIVES To compare triple therapy with sequential and concomitant therapies directly in a head-to-head comparison in Helicobacter pylori-infected patients. DESIGN Patients were allocated randomly as follows: a triple therapy with esomeprazole (20 mg), amoxicillin (1000 mg) and clarithromycin (500 mg) twice daily for 7 days; a sequential therapy with 5 days of esomeprazole (20 mg) and amoxicillin (1000 mg) twice daily, followed by 5 days of esomeprazole (20 mg), clarithromycin (500 mg) and metronidazole (400 mg) twice daily; or a concomitant therapy consisting of esomeprazole (20 mg), amoxicillin (1000 mg), clarithromycin (500 mg) and metronidazole (400 mg) twice daily for 7 days. RESULTS A total of 356 consecutive patients were included. The eradication rates for the triple, sequential and concomitant therapies were 83.6% [95% confidence interval (CI) 76.9-90.4%], 94.2% (95% CI 90.0-98.4%) and 91.7% (95% CI 86.7-96.6%), respectively, in the intention-to-treat population. The differences were significant only between triple and sequential therapies (P=0.01). The primary resistance rates to amoxicillin, clarithromycin and metronidazole were 0.6, 10.5 and 25.9%, respectively. Concomitant therapy was significantly better than triple therapy in cases with clarithromycin resistance (P=0.01). CONCLUSION Ten-day sequential therapy was significantly better than 7-day triple therapy in a clinical setting with low rates of clarithromycin and dual resistance. Concomitant therapy was significantly better than standard triple therapy in the subgroup of patients with clarithromycin-resistant strains.

Abstract
OBJECTIVES We evaluate the efficacy of concomitant therapy for Helicobacter pylori infection and the associated factors that influence it in China, where it has not previously been investigated. METHODS In this prospective study, 374 consecutive patients with H. pylori infection were randomly assigned to 10 day regimens of concomitant therapy with different proton pump inhibitors: esomeprazole (20 mg)/omeprazole (20 mg), amoxicillin (1000 mg), clarithromycin (500 mg) and metronidazole (400 mg). All drugs were administered twice daily. A [(13)C]urea breath test was performed at least 4 weeks after the completion of treatment. Gene polymorphisms and antimicrobial susceptibility were determined. RESULTS A total of 374 patients with active, uncomplicated duodenal ulcer disease were enrolled in the study (187 cases in each group). The overall eradication rate resulting from concomitant therapy was 90.7% (PP) and 86.1% (ITT) and the eradication rate was significantly higher in the group that received an esomeprazole-based regimen compared with the group that received an omeprazole-based regimen [95.4% versus 86.0%, respectively, P = 0.003 (PP) and 89.8% versus 82.4%, P = 0.036 (ITT), respectively]. Moreover, the omeprazole-based regimen was an independent risk factor for treatment failure (P = 0.039), as were CYP2C19 extensive metabolizer (P = 0.005), clarithromycin (P = 0.000) and metronidazole resistance (P = 0.000). In addition, CYP2C19 polymorphisms and antibiotic resistance had a synergistic effect on eradication rates. The majority of side effects were mild and none was serious. CONCLUSIONS The 10 day concomitant therapy yielded an eradication rate of nearly 90%. Antibiotic resistance, CYP2C19 polymorphisms and their interactions were closely associated with regimen efficacy.

Abstract
BACKGROUND With markedly increased antibiotic resistance and unsatisfactory efficacies of common empiric eradication regimens in the mainland of China, tailored therapy may be the best choice to achieve good efficacy. This study compared the eradication rates, safety, and compliance of tailored therapy to those of triple therapy plus bismuth and concomitant therapy in the naïve patients with Helicobacter pylori infection. MATERIALS AND METHODS Between September 2013 and April 2014, 1050 patients with H. pylori infection at three tertiary hospitals were randomly assigned to 10-day treatment with tailored, triple plus bismuth, or concomitant regimens. In tailored therapy, medications were adjusted according to clarithromycin sensitivity and cytochrome P450 isoenzyme 2C19 genotype. The antimicrobial susceptibility testing (E test) was performed. Eradication status was assessed 4-12 weeks after treatment. RESULTS The eradication rate was significantly higher in tailored group than in triple plus bismuth and concomitant groups in both intention-to-treat (88.7 vs 77.4 vs 78.3%, p < .001) and per-protocol (93.3 vs 87.0 vs 87.4%, p = .021) analyses in a setting with high antibiotic resistance (clarithromycin 48.8%, metronidazole 65.7%, and dual resistance 35.3%). Significantly, fewer adverse effects occurred in tailored group than in concomitant group (22.0 vs 31.7%, p = .018). The eradication rates of dual clarithromycin and metronidazole resistance, isolated clarithromycin resistance, isolated metronidazole resistance, and dual susceptible were 78.7, 82.4, 94.8, and 94.4% in triple therapy plus bismuth and 75.9, 87.2, 92.9, and 95.2% in concomitant therapy, respectively. CONCLUSIONS First-line tailored therapy achieves significantly higher eradication rates and fewer side effects, compared to triple therapy plus bismuth and concomitant therapy in a setting with high rates of clarithromycin and metronidazole resistance.

Abstract
BACKGROUND Probiotic delivery systems are widely used nutraceutical products for the supplementation of natural intestinal flora. These delivery systems vary greatly in the effectiveness to exert health benefits for a patient. This study focuses on providing probiotic living cells with a physical barrier against adverse environmental conditions. MATERIALS AND METHODS Microencapsulation of the selected lactic acid bacteria (LAB) using chitosan and alginate was performed. Physical examination of the formulated LAB microcapsules was observed using phase contrast inverted microscope and scanning electron microscope (SEM). Finally, the survival of microencapsulated and noncapsulated bacteria was cheeked in the simulated human gastric tract (GT). The potential antimicrobial activity of the most potent microencapsulated LAB strain was in vivo evaluated in rabbit models. RESULTS Microencapsulated L. plantarum, L. acidophilus, and L. bulgaricus DSMZ 20080 were loaded with 1.03 × 10(10) CFU viable bacteria/g, 1.9 × 10(10) CFU viable bacteria/g, and 5.5 × 10(9) CFU viable bacteria/g, respectively. The survival of microencapsulated cells was significantly higher than that of the free cells after exposure to simulated gastric juice (SGJ) at pH 2. Additionally, in simulated small intestine juice (SSJ), larger amounts of the selected LAB cells were found, whereas in simulated colon juice (SCJ), the released LAB reached the maximum counts. In vivo results pointed out that an 8-week supplementation with a triple therapy of a microencapsulated L. plantarum, L. acidophilus, and L. bulgaricus DSMZ 20080 might be able to reduce H. pylori. CONCLUSION Microencapsulated probiotics could possibly compete with and downregulate H. pylori infection in humans.

Abstract
BACKGROUND Nonbismuth quadruple (concomitant) regimen is recommended for first-line empirical Helicobacter pylori (HP) eradication treatment when clarithromycin resistance is more than 15-20%. Our objective was to evaluate the efficacy and tolerability of concomitant versus antimicrobial susceptibility-guided treatment in an area with high rates of clarithromycin resistance. METHODS Three hundred consecutive HP-infected patients received antimicrobial susceptibility-guided therapy or empirical concomitant therapy for 10 days. The concomitant regimen was omeprazole (20 mg/12 hour), amoxicillin (1 g/12 hour), clarithromycin (500 mg/12 hour), and metronidazole (500 mg/12 hour) (OACM). Patients diagnosed by culture received one of three combinations of antibiotics based on susceptibility results: omeprazole, amoxicillin, and clarithromycin (OAC); omeprazole, amoxicillin, and levofloxacin (OAL); or omeprazole, amoxicillin, and metronidazole (OAM), at the aforementioned doses (and 500 mg/12 hour in the case of levofloxacin). Eradication was confirmed with a (13)C urea breath test, 6 weeks after treatment. Adverse events and adherence were assessed with questionnaires and reviewing medication sachets. RESULTS The mean age was 50 years, 59% were women, and 14% had peptic ulcers. Concomitant and antimicrobial susceptibility-guided eradication rates were, respectively, 87% and 94% by intention-to-treat (p = .08) and 89% and 95% (p = .08) per protocol per-protocol analysis. Adverse effects were reported in 31% of patients on OACM and 15% of those on susceptibility-guided therapy (p < .05). CONCLUSIONS For HP eradication in a region with high rates of multiple drug resistance, antimicrobial susceptibility-guided therapy is more effective than empirical concomitant therapy.

Abstract
Treatments with bismuth-containing quadruple therapy (QT), sequential therapy (ST), or concomitant therapy (CT) have been proposed as empirical first-line regimens for Helicobacter pylori. We compared the efficacy and tolerability of 10 days bismuth-containing quadruple QT, 10 days ST, and 10 days CT with as first-line treatments for H. pylori in a randomized crossover study. The subjects were randomly divided into three groups. The first 130 patients were treated with rabeprazole, bismuth potassium citrate, metronidazole, and tetracycline for 10 days. The second 130 patients in the sequential group were treated with rabeprazole and amoxicillin for 5 days, and then rabeprazole, clarithromycin, and metronidazole for an additional 5 days. The last 130 patients in the concomitant group were treated with rabeprazole, amoxicillin, clarithromycin, and metronidazole for 10 days. H. pylori eradication was confirmed by urea breath test at 6 weeks. The primary outcome was eradication rates of first-line treatment by intention to treat and per protocol (PP) analyzes. There was no difference between the average ages and the male/female ratio of the groups. The PP analysis was performed on 121, 119, and 118 patients in the QT, ST, and CT groups, respectively. In the PP analysis, the successful eradication 94.2% (114/121), 95.0% (113/119), and 95.8% (113/118) the QT, ST, and CT groups, respectively. There was no significant difference among the three groups (p = 0.86). 10 days QT, ST, and CT are highly effective as empirical first-line therapies for H. pylori in the region with high clarithromycin resistance.

Abstract
OBJECTIVES Comparison of Helicobacter pylori eradication rates, side effects, compliance, cost, and ulcer recurrence of sequential therapy (ST) with that of concomitant therapy (CT) in patients with perforated duodenal ulcer following simple omental patch closure. METHODS Sixty-eight patients with perforated duodenal ulcer treated with simple closure and found to be H. pylori positive on three months follow-up were randomized to receive either ST or CT for H. pylori eradication. Urease test and Giemsa stain were used to assess for H. pylori eradication status. Follow-up endoscopies were done after 3 months, 6 months, and 1 year to evaluate the ulcer recurrence. RESULTS H. pylori eradication rates were similar in ST and CT groups on intention-to-treat (ITT) analysis (71.43% vs 81.80%,P = 0.40). Similar eradication rates were also found in per-protocol (PP) analysis (86.20% vs 90%,P = 0.71). Ulcer recurrence rate in ST groups and CT groups at 3 months (17.14% vs 6.06%,P = 0.26), 6 months (22.86% vs 9.09%,P = 0.19), and at 1 year (25.71% vs 15.15%,P = 0.37) of follow-up was also similar by ITT analysis. Compliance and side effects to therapies were comparable between the groups. The most common side effects were diarrhoea and metallic taste in ST and CT groups, respectively. A complete course of ST costs Indian Rupees (INR) 570.00, whereas CT costs INR 1080.00. CONCLUSION H. pylori eradication rates, side effects, compliance, cost, and ulcer recurrences were similar between the two groups. The ST was more economical compared with CT.

Abstract
Background. The decline of Helicobacter pylori (H. pylori) eradication rates with standard triple therapy resulted in a search for novel therapies for first-line therapy of H. pylori infection. Aim. The aim of the study is to compare the efficacy of concomitant therapy with sequential therapy as the first-line therapy of H. pylori eradication. Methods. We reviewed medical records of patients who were confirmed to have H. pylori infection and received eradication treatment from September 2012 to March 2015. The concomitant group was treated with rabeprazole, amoxicillin, clarithromycin, and metronidazole for 7 days. The sequential group was treated with rabeprazole and amoxicillin for 5 days and then rabeprazole, clarithromycin, and metronidazole for an additional 5 days. Six weeks after the treatment period, patients in both groups underwent 13C-Urea breath test (UBT) to confirm H. pylori eradication. Results. The eradication rate was 90.3% in the concomitant group and 85.5% in the sequential group. However, the eradication rates between the two groups showed no statistical difference (P = 0.343). Conclusion. No statistical difference was found in eradication rates between the two groups. However, in areas where antibiotic resistance is high, concomitant therapy may be more effective than sequential therapy for H. pylori eradication.
