Equivalence Trial of the Non-Bismuth 10-Day Concomitant and 14-Day Hybrid Therapies for Helicobacter pylori Eradication in High Clarithromycin Resistance Areas. Antibiotics (Basel) 2024; 13:280. [PMID: 38534715 DOI: 10.3390/antibiotics13030280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Revised: 03/12/2024] [Accepted: 03/15/2024] [Indexed: 03/28/2024] Open
Abstract
Background and aim: We conducted an equivalence trial of quadruple non-bismuth "concomitant" and "hybrid" regimens for H. pylori eradication in a high clarithromycin resistance area. Methods: There were 321 treatment-naïve H. pylori-positive individuals in this multicenter clinical trial randomized to either the hybrid (esomeprazole 40 mg/bid, amoxicillin 1 g/bid for 7 days, then 7 days esomeprazole 40 mg/bid, amoxicillin 1 g/bid, clarithromycin 500 mg/bid, and metronidazole 500 mg/bid) or the concomitant regimen (all medications given concurrently bid for 10 days). Eradication was tested using histology and/or a 13C-urea breath test. Results: The concomitant regimen had 161 patients (90F/71M, mean 54.5 years, 26.7% smokers, 30.4% ulcer) and the hybrid regimen had 160 (80F/80M, mean 52.8 years, 35.6% smokers, 31.2% ulcer). The regimens were equivalent, by intention to treat 85% and 81.8%, (p = 0.5), and per protocol analysis 91.8% and 87.8%, (p = 0.3), respectively. The eradication rate by resistance, between concomitant and hybrid regimens, was in susceptible strains (97% and 97%, p = 0.6), clarithromycin single-resistant strains (86% and 90%, p = 0.9), metronidazole single-resistant strains (96% and 81%, p = 0.1), and dual-resistant strains (70% and 53%, p = 0.5). The side effects were comparable, except for diarrhea being more frequent in the concomitant regimen. Conclusions: A 14-day hybrid regimen is equivalent to a 10-day concomitant regimen currently used in high clarithromycin and metronidazole resistance areas. Both regimens are well tolerated and safe.

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
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
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.

Abstract
Helicobacter pylori (H. pylori) infection is associated with the development of multiple diseases. The eradication rate of H. pylori has gradually decreased, suggesting the need to discover more effective therapies. This study aimed to compare the effectiveness of first-line treatments including high-dose dual therapy (HDDT), bismuth-based quadruple therapy (BQT), sequential therapy (ST), concomitant therapy (CT) and hybrid therapy (HT) by network meta-analysis (NMA). A comprehensive search on PubMed, Embase, Cochrane Library and Web of Science, was performed from their inception to 1 September 2019. A network analysis of randomized controlled trials (RCTs) comparing first-line therapies were carried out using Stata 14.0 and Revman 5.2. Moreover, a sensitivity analysis was conducted by omitting non-Asian studies. Finally, 41 RCTs with 14 119 patients were included. The NMA showed that, in terms of eradication rate, ST for 10 days (ST-10) was significantly lower than CT for 10 or 14 days (CT ≥ 10). Sensitivity analysis among the Asian population showed that ST-10 denoted the lowest effectiveness among the interventions. The ranking results based on probability showed that HDDT ranked first for the eradication rate. As for adverse events, HDDT was significantly less than BQT and CT regardless of duration, while BQT for 14 days represented higher adverse events than ST, HT and CT ≥ 10. HDDT ranked first among the therapies. In conclusion, HDDT for 14 days appeared to be the most optimal first-line therapy for H. pylori among the Asian population with comparable efficacy and compliance but causing fewer adverse events.

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.

Abstract
Introduction: Eradication of Helicobacter pylori (H. pylori) becomes more challenging due to increasing antimicrobial resistance. Consequently, the performance of clarithromycin-containing triple therapies is now declining to unacceptable levels and should be abandoned unless a prior susceptibility test precludes clarithromycin resistance.Areas covered: This review summarizes updated evidence concerning new and advancing pharmacotherapy options for H. pylori eradication.Expert opinion: Due to the declining efficacy of legacy triple therapies, most guidelines recommend bismuth quadruple therapy as the best initial empiric treatment. Concomitant, sequential and hybrid therapies are remarkable bismuth-free quadruple options, provided that dual clarithromycin-metronidazole resistance is low. Levofloxacin-, rifabutin-, furazolidone- and sitafloxacin-containing regimens remain useful, particularly as salvage options. To eradicate H. pylori in line with the rules of antibiotic stewardship, susceptibility-guided treatment appears as the ideal approach. However, the feasibility and cost-effectiveness of universal pre-treatment susceptibility testing warrants further evaluation. Molecular testing methods promise convenient characterization of H. pylori antibiotic susceptibility. High-dose dual therapy (proton-pump-inhibitor plus amoxicillin) and vonoprazan, a more potent acid inhibitor that likely enhances the activity of amoxicillin, are promising alternatives that could decrease misuse of antibiotics. Addition of certain probiotics could somewhat increase the performance of H. pylori eradication regimens, while improving tolerability.

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.

Abstract
GOALS The aim of this study was to investigate the implementation of a 14-day quadruple nonbismuth concomitant regimen, as proposed by recent Guidelines and Consensus Statements. BACKGROUND In Greece, a region with >20% clarithromycin resistance where bismuth is unavailable, the 10-day quadruple concomitant scheme has already been adopted as the accepted first-line Helicobacter pylori eradication treatment. STUDY Our prospective randomized study included 364 patients with newly diagnosed H. pylori infection, randomized to receive a 10-day or a 14-day nonbismuth quadruple concomitant scheme. Treatment outcome was assessed by C-urea breath test and/or histology at least 4 weeks after therapy. Intention to treat and per protocol analyses of the eradication rates were performed. Secondary endpoints included patient adherence, safety, and the impact of prior antibiotic exposure in treatment efficacy. RESULTS The overall eradication rates of the 2 treatments were 87.9% versus 87.4% in the intention to treat analysis, P=1.000, and 93% versus 94.1%, P=0.859, in the per protocol analysis for the 10-day and the 14-day treatment group, respectively. Both groups displayed excellent compliance rates (99.5% for the 10-day vs. 96.2% for the 14-day treatment duration, P=0.067). As regards treatment safety, serious adverse events that led to the discontinuation of both regimens were few, with no statistical difference between the 2 groups (0.5% in the 10-day group and 2.2% in the 14-day group, P>0.05). Previous antibiotic exposure was not significant with regard to treatment efficacy. CONCLUSION In Greece, the 10-day concomitant nonbismuth quadruple regimen for first-line treatment remains the most efficient strategy for H. pylori eradication.

Evaluation of the Direct Economic Cost per Eradication Treatment Regimen against Helicobacter pylori Infection in Greece: Do National Health Policy-Makers Need to Care? ACTA ACUST UNITED AC 2020; 56:medicina56030133. [PMID: 32197498 PMCID: PMC7142601 DOI: 10.3390/medicina56030133] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/09/2020] [Accepted: 03/10/2020] [Indexed: 12/15/2022]
Abstract
Helicobacter pylori (Hp) management has undoubtedly resulted in a notable economic burden on healthcare systems globally, including Greece. Its cost has never been estimated so far, especially during the recent 10-year unprecedented financial crisis. Direct medical and procedural costs for one attempt "outpatient" Hp eradication treatment were estimated as the following: (I) first-line regimens: 10 and 14 days standard triple, 10 and 14 days sequential, 10 and 14 days concomitant non-bismuth quadruple, 14 days hybrid, (II) second-line salvage regimens: 10 and 14 days levofloxacin-containing triple regimens. Treatment costs using prototypes and/or generic drugs were calculated. Drug prices were collected and confirmed from two official online medical databases including all medicines approved by the Greek National Organization for Medicines. Regimens based on generics were more affordable than prototypes and those including pantoprazole yielded the lowest prices (mean: 27.84 €). Paradoxically, 10-day concomitant and 14-day hybrid regimens (currently providing good (90-94%) first-line eradication rates in Greece) cost the same (mean: 34.76 €). The expenditures for Hp eradication treatment regimens were estimated thoroughly for the first time in Greece. These data should be taken into account by Public Health policymakers both in Greece and the European Union, aiming for a better and less expensive therapeutic approach.

Abstract
INTRODUCTION Helicobacter pylori infection (H pylori-I) affects more than half of the global population and consists an important burden to public health and healthcare expenditures, by contributing to many diseases' pathogenesis. AIM This study aimed to evaluate the current nonbismuth quadruple eradication regimens in a high antibiotic resistance area, such as Greece, concerning their cost-effectiveness, especially during financial crisis period. MATERIALS AND METHODS Eight hundred and nine patients who received eradication treatment against H pylori-I were included to evaluate five different regimens, using amoxicillin, clarithromycin, and metronidazole as antibiotics and one proton-pump inhibitor, based on their current eradication rates. Regimes compared 10-day concomitant use of (a) pantoprazole or (b) esomeprazole; 10-day sequential use of (c) pantoprazole or (d) esomeprazole; and 14-day hybrid using esomeprazole. Cost-effectiveness analysis ratio (CEAR) and incremental cost-effectiveness ratios were calculated taking into account all direct costs and cases who needed second-line treatment. Additionally, sensitivity analysis was performed to predict all potential combinations. RESULTS Ten-day concomitant regimen with esomeprazole was characterized by the lowest CEAR (179.17€) followed by the same regimen using pantoprazole (183.27€). Hybrid regimen, although equivalent in eradication rates, was found to have higher CEAR (187.42€), whereas sequential regimens were not cost-effective (CEAR: 204.12€ and 216.02€ respectively). DISCUSSION This is the first study evaluating the cost-effectiveness of H pylori-I treatment regimens in a high clarithromycin-resistance (≈26.5%) European area, suggesting the 10-day concomitant regimen with generics using esomeprazole 40 mg as the most appropriate one. National and regional guidelines should include cost-effectiveness in their statements, and further studies are required to clarify the necessity of a wide "test and treat" policy for H pylori-I.

Abstract
The Hellenic Society of Gastroenterology recently organized the “Hellenic consensus on Helicobacter pylori (H. pylori) infection”. The aim of this publication is to report the guidelines in order to aid the national gastroenterology community in the management of H. pylori infection. Forty-one delegates from all Greek regions, including gastroenterologists, pathologists, clinical microbiologists, epidemiologists and basic scientists, were invited to this meeting. The participants were allocated to 1 of the 4 main topics of the meeting: i.e., H. pylori diagnosis and association with diseases; H. pylori and gastric cancer; H. pylori and extragastric associated disorders; and H. pylori treatment. The results of each subgroup were submitted to a final consensus vote that included all participants. Relevant data based on international and Greek publications were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. The cutoff level of 70% was considered as acceptance for the final statement. It is hoped that the recommendations and conclusions of this report will guide Greek doctors in their daily practice concerning the management of H. pylori infection.

Optimal duration of concomitant nonbismuth quadruple therapy as first-line therapy for Helicobacter pylori: a prospective, open-label, comparative study. Eur J Gastroenterol Hepatol 2019; 31:1206-1210. [PMID: 31441794 DOI: 10.1097/meg.0000000000001517] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/20/2022]
Abstract
BACKGROUND Concomitant nonbismuth quadruple therapy is recommended as first-line treatment for Helicobacter pylori infection in high clarithromycin resistance areas, but the ideal duration of the regimen remains elusive. Aim of this study was to assess the efficacy and tolerability of 10- versus 14-day concomitant therapy for H. pylori eradication in an area of high clarithromycin and low dual clarithromycin/metronidazole resistance. METHODS This was a prospective, open-label study including adult patients with H. pylori infection without previous treatment, from September 2014 to June 2017. Concomitant therapy consisting of pantoprazole 40 mg, amoxicillin 1g, clarithromycin 500 mg, and a nitroimidazole 500 mg was administered twice daily for 10 days in the first phase and for 14 days in the second phase of the study. Efficacy and side effects were compared between groups using chi-square and Fisher's exact tests. RESULTS In per protocol analysis, rates of eradication for the 10- and 14-day regimen were 91.9% (114/124) and 90.9% (110/121), respectively (P = 0.77). In intention to treat analysis, rates of eradication were lower than 90%. Specifically, rates were 86.3% (114/132) for the 10-day regimen and 85.2% (110/129) for the 14-day regimen (P = 0.8). Side effects, present in 31.3% of treated patients, were significantly more common in the 14-day group (P = 0.015). Four patients discontinued treatment, all in the 14-day group. CONCLUSIONS Ten day concomitant nonbismuth quadruple therapy for H. pylori is highly efficacious and better tolerated than the 14-day regimen. Thus, 10-day therapy may be preferred as first-line treatment in clinical practice.

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
While the prevalence of Helicobacter pylori (H. pylori) infection is decreasing in Korea, the incidence of gastric cancer remains high, emphasizing the importance of H. pylori eradication. A new treatment strategy is needed as the eradication rate with standard triple therapy, which is currently the standard first-line regimen for H. pylori infection, has decreased below the optimum level. The major cause of eradication failure is increased antibiotic resistance. Sequential, concurrent, and hybrid therapies that include clarithromycin produce higher eradication rates than conventional standard triple therapy. However, the effectiveness of these treatments is limited in regions where the resistance rate to various antibiotics is high. Bismuth quadruple therapy is another alternative therapy, but again the eradication rate is not sufficiently high. Tailored therapy based on individual characteristics, including antibiotic susceptibility, may be ideal, but there are several limitations for clinical application and further research is needed. New potassium-competitive acid blocker-based therapies could emerge as effective alternatives in the near future. A consensus is needed to establish a strategy for applying new eradication therapies in Korea.

Abstract
AIM To assess the efficacy and safety of fourth-generation quinolones for Helicobacter pylori (H. pylori) eradication, we conducted this systematic review and meta-analysis of randomized clinical trials. METHODS Major literature databases (PubMed, EMBASE and the Cochrane Central Register of Controlled Trials) were searched for relevant articles published prior to February 2018. We performed a meta-analysis of all randomized clinical trials that examined the efficacy of H. pylori eradication therapies and included fourth-generation quinolones in the experimental arm. Subgroup analyses by regions and different types of fourth-generation quinolones were also performed. RESULTS Ten studies including a total of 2198 patients were assessed. A meta-analysis of randomized controlled trials showed that the eradication rate of therapies containing non-fourth-generation quinolones was significantly lower than that of therapies containing fourth-generation quinolones by intention-to-treat (ITT) analysis [75.4% vs 81.8%; odds ratio (OR) = 0.661; 95% confidence interval (CI): 0.447-0.977; P = 0.038]. This analysis also showed that the eradication rate of the therapies containing non-fourth-generation quinolones was inferior to that of therapies containing fourth-generation quinolones by per-protocol analysis (79.1% vs 84.7%; OR = 0.663; 95%CI: 0.433-1.016; P = 0.059). Moreover, the occurrence of side effects was significantly different between the control and experimental groups by ITT analysis (30.6% vs 19.5%; OR = 1.874; 95%CI: 1.120-3.137; P = 0.017). The sub-analyses also showed significant differences in moxifloxacin therapies vs other fourth-generation quinolone therapies (84.3% vs 71.9%) and in Asian vs European groups (76.7% vs 89.1%). CONCLUSION Therapies containing fourth-generation quinolones achieved a poor eradication rate in the treatment of H. pylori infection. Such regimens might be useful as a rescue treatment based on antimicrobial susceptibility testing. Different antibiotics should be chosen in different regions.

Abstract
ABSTRACT Significant progress has been obtained since the III Brazilian Consensus Conference on H. pylori infection held in 2012, in Bento Gonçalves, Brazil, and justify a fourth meeting to establish updated guidelines on the current management of H. pylori infection. Therefore, the Núcleo Brasileiro para Estudo do Helicobacter pylori e Microbiota (NBEHPM), association linked to Brazilian Federation of Gastroenterology (FBG) held its fourth meeting again in Bento Gonçalves, RS, Brazil, on August 25-27, 2017. Twenty-six delegates, including gastroenterologists, endoscopists, and pathologists from the five regions of Brazil as well as one international guest from the United States, participated in the meeting. The participants were invited based on their knowledge and contribution to the study of H. pylori infection. The meeting sought to review different aspects of treatment for infection; establish a correlation between infection, dyspepsia, intestinal microbiota changes, and other disorders with a special emphasis on gastric cancer; and reassess the epidemiological and diagnostic aspects of H. pylori infection. Participants were allocated into four groups as follows: 1) Epidemiology and Diagnosis, 2) Dyspepsia, intestinal microbiota and other afections, 3) Gastric Cancer, and, 4) Treatment. Before the consensus meeting, participants received a topic to be discussed and prepared a document containing a recent literature review and statements that should be discussed and eventually modified during the face-to-face meeting. All statements were evaluated in two rounds of voting. Initially, each participant discussed the document and statements with his group for possible modifications and voting. Subsequently, during a second voting in a plenary session in the presence of all participants, the statements were voted upon and eventually modified. The participants could vote using five alternatives: 1) strongly agree; 2) partially agree; 3) undecided; 4) disagree; and 5) strongly disagree. The adopted consensus index was that 80% of the participants responded that they strongly or partially agreed with each statement. The recommendations reported are intended to provide the most current and relevant evidences to management of H. pylori infection in adult population in Brazil.

Abstract
Introduction Helicobacter pylori infection is encountered in more than 50% of the world population. A high rate of clarithromycin resistance is observed among Helicobacter pylori strains in some regions because clarithromycin is a drug commonly used for the treatment of other infections. Aim To identify an efficient eradication protocol for patients infected with H. pylori and to suggest an alternative first-line therapy particularly in countries with high clarithromycin resistance. Material and methods Patients (18-75 years old) having dyspeptic complaints in a 1-year period and diagnosed with H. pylori infection by gastric biopsy were included and randomised to three groups, each receiving different sequential eradication therapy (LAM-B: lansoprazole, amoxicillin, metronidazole, bismuth: LAM-T: lansoprazole, amoxicillin, metronidazole, tetracycline; LAM-BT: lansoprazole, amoxicillin, metronidazole, bismuth, tetracycline). Eradication was evaluated via urea breath test. Results This study included 166 patients (mean age: 40 ±12 years; female, 68.7%) with H. pylori infection. Among them, 50 (30.1%) were in the LAM-B group, 59 (35.5%) were in the LAM-T group, and 57 (34.3%) were in the LAM-BT group. The non-steroidal anti-inflammatory drug use was the lowest in the LAM-BT group. Eradication rates were over 80% and similar in each group, with the highest rate in the LAM-BT group (93%). Adverse event rate was the highest in the LAM-T group. Helicobacter pylori eradication was achieved in 143 (86.1%) patients. Conclusions The combination regimens without clarithromycin achieved an eradication rate over 80% in all groups. Knowing and monitoring the regional antibiotic resistance rates is important for successful treatment of H. pylori infections.

Abstract
BACKGROUND The efficacy of the standard triple therapy for Helicobacter pylori eradication has decreased to an unacceptable level. We aimed to compare the efficacy of sequential and concomitant therapies as for the first-line treatments for H. pylori eradication and analyzed the effect of clarithromycin resistance on the eradication rates. MATERIALS AND METHODS Four hundred and seventy-eight patients with H. pylori infection were randomly assigned to either concomitant therapy (amoxicillin 1000 mg with clarithromycin 500 mg, metronidazole 500 mg, and pantoprazole 40 mg twice daily for 10 days) or sequential therapy (amoxicillin 1000 mg with pantoprazole 40 mg twice daily for 5 days, followed by clarithromycin 500 mg with metronidazole 500 mg and pantoprazole 40 mg twice daily for 5 days). The success of the eradication was evaluated 4-5 weeks after treatment completion. To evaluate the efficacy of the two regimens according to clarithromycin sensitivity, dual-priming oligonucleotide-based multiplex-polymerase chain reaction was also performed in the final third of the enrolled study populations. RESULTS The eradication rates with concomitant or sequential therapy were 81.9% and 76.6% (P = .153) in intention-to-treat analysis, and 93.4% and 84.8% (P = .004) in per-protocol analysis, respectively. Among the 156 patients for whom dual-priming oligonucleotide-based multiplex-polymerase chain reaction was performed, 17.9% were clarithromycin resistant, and the efficacy of concomitant therapy was better than sequential therapy in the clarithromycin-resistant strains (100% vs 58.3%, P = .010). CONCLUSION Concomitant therapy was superior to sequential therapy as the first-line treatment for H. pylori eradication, especially in clarithromycin-resistant strains in Korea.

Abstract
Many interesting articles have been published from different parts of the world over the last year assessing various issues around Helicobacter pylori eradication therapy. This article will address the published literature over the last year pertaining to the topic of treatment of H. pylori infection. The main themes that emerge are assessing the efficacy of standard triple therapy, as well as exploring new first-line treatments, mainly optimized nonbismuth-containing and bismuth-containing quadruple therapies with some promising data also emerging on dual therapy. There was also considerable progress in investigating antibiotic resistance rates with much more data emerging from varied parts of the world compared to recent years. Advances in the use of adjunctive therapies, especially probiotic therapies have also been made. Undoubtedly, the eradication of H. pylori remains a worthwhile goal to alleviate the burden of diseases caused by the complications of this infection, including dyspepsia, peptic ulcer disease, and gastric cancer.

Randomized clinical trial comparing ten day concomitant and sequential therapies for Helicobacter pylori eradication in a high clarithromycin resistance area. Eur J Intern Med 2016; 32:84-90.

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
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
From the first isolation of Helicobacter pylori (H. pylori) from the gastric mucosa by Marshall and Warren in 1983, 33 years have passed. H. pylori has been found to be closely associated not only with chronic gastric diseases but also with multiple system diseases. Advances in research of H. pylori infection has led to a better understanding of the pathogenicity of H. pylori and the prevention and treatment of related disease. In 2015, Professor Zou's team developed oral recombinant H. pylori vaccine, which is promising in the prevention of H. pylori infection. Japan aims to reduce the risk of H. pylori infection in the whole population in 2014 to reduce the incidence of gastric cancer, which has caused widespread concern. H. pylori infection is a kind of infectious disease, and the infection rate in China is about 56%.Therefore, it is of great clinical importance to strengthen the research on bacteriology and pathogenesis of H. pylori, improve the prevention and treatment related diseases, and seek antibacterial regimens with better efficacy and lower drug resistance.
