Seddik H, Benass J, Berrag S, Sair A, Berraida R, Boutallaka H. Optimized sequential therapy vs 10- and 14-d concomitant therapy for eradicating Helicobacter pylori: A randomized clinical trial. World J Gastroenterol 2024; 30:556-564. [PMID: 38463026 PMCID: PMC10921140 DOI: 10.3748/wjg.v30.i6.556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/26/2023] [Accepted: 12/29/2023] [Indexed: 02/05/2024] Open
Abstract
BACKGROUND A cure for Helicobacter pylori (H. pylori) remains a problem of global concern. The prevalence of antimicrobial resistance is widely rising and becoming a challenging issue worldwide. Optimizing sequential therapy seems to be one of the most attractive strategies in terms of efficacy, tolerability and cost. The most common sequential therapy consists of a dual therapy [proton-pump inhibitors (PPIs) and amoxicillin] for the first period (5 to 7 d), followed by a triple therapy for the second period (PPI, clarithromycin and metronidazole). PPIs play a key role in maintaining a gastric pH at a level that allows an optimal efficacy of antibiotics, hence the idea of using new generation molecules. AIM To compare an optimized sequential therapy with the standard non-bismuth quadruple therapies of 10 and 14 d, in terms of efficacy, incidence of adverse effects (AEs) and cost. METHODS This open-label prospective study randomized 328 patients with confirmed H. pylori infection into three groups (1:1:1): The first group received quadruple therapy consisting of twice-daily (bid) omeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg for 10 d (QT-10), the second group received a 14 d quadruple therapy following the same regimen (QT-14), and the third group received an optimized sequential therapy consisting of bid rabeprazole 20 mg plus amoxicillin 1 g for 7 d, followed by bid rabeprazole 20 mg, clarithromycin 500 mg and metronidazole 500 mg for the next 7 d (OST-14). AEs were recorded throughout the study, and the H. pylori eradication rate was determined 4 to 6 wk after the end of treatment, using the 13C urea breath test. RESULTS In the intention-to-treat and per-protocol analysis, the eradication rate was higher in the OST-14 group compared to the QT-10 group: (93.5%, 85.5% P = 0.04) and (96.2%, 89.5% P = 0.03) respectively. However, there was no statistically significant difference in eradication rates between the OST-14 and QT-14 groups: (93.5%, 91.8% P = 0.34) and (96.2%, 94.4% P = 0.35), respectively. The overall incidence of AEs was significantly lower in the OST-14 group (P = 0.01). Furthermore, OST-14 was the most cost-effective among the three groups. CONCLUSION The optimized 14-d sequential therapy is a safe and effective alternative. Its eradication rate is comparable to that of the 14-d concomitant therapy while causing fewer AEs and allowing a gain in terms of cost.

The nonadherence and risk factors of eradication failure by sequential therapy as first-line anti-Helicobacter pylori treatment in real-world clinical practice. Helicobacter 2024; 29:e13033. [PMID: 37950342 DOI: 10.1111/hel.13033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 09/25/2023] [Accepted: 10/23/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND The eradication rates of sequential therapy are high in clinical trials; however, the adherence for follow-up or the patient population in a real-world setting might be different from those in trails. This study investigates the effectiveness of sequential therapy in a real-world setting and the factors that lead to treatment failure. MATERIALS AND METHODS In this retrospective study, patients receiving sequential therapy as a first-line anti-Helicobacter pylori (H. pylori) treatment in a real-world setting were reviewed. The age adjusted Charlson Comorbidity Index (age-CCI) and baseline variety of medications were reviewed to determine factors correlated with nonadherence for post-treatment testing and H. pylori eradication failure. RESULTS A total of 1053 patients were reviewed. A total of 579 patients receiving sequential therapy were included in the analyses. Among them, 462 received post-treatment testing and were placed into the follow-up group. Thus, the post-treatment testing rate was 79.8%. Stroke was an independent factor of nonadherence for post-treatment testing. In the follow-up group, the eradication failure rate was 8.2%. Female sex (odds ratio [OR] 2.41 [95% CI 1.16-5.03], p = 0.02) and age-CCI ≥2 (OR 3.16 [1.05-9.48], p = 0.04) were independent factors of H. pylori eradication failure. The eradication failure rates were 14.4%, 7.8%, 7.1%, and 3.1% for the females with age-CCI ≥2, females with age-CCI <2, males with age-CCI ≥2, and males with age-CCI <2 subgroups, respectively (p = 0.027). CONCLUSIONS In a real-world setting, the adherence rate of post-treatment testing for sequential therapy as a first-line anti-H. pylori treatment was found to be suboptimal. Female sex and age-CCI ≥2 were independent factors of eradication failure.

Practice guidelines for the management of Helicobacter pylori infection: The Saudi H. pylori Working Group recommendations. Saudi J Gastroenterol 2023; 29:326-346. [PMID: 36204804 PMCID: PMC10754383 DOI: 10.4103/sjg.sjg_288_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 08/07/2022] [Accepted: 08/19/2022] [Indexed: 11/06/2022] Open
Abstract
The eradication rates for Helicobacter pylori globally are decreasing with a dramatic increase in the prevalence of antibiotic resistant bacteria all over the world, including Saudi Arabia. There is no current consensus on the management of H. pylori in Saudi Arabia. The Saudi Gastroenterology Association developed these practice guidelines after reviewing the local and regional studies on the management of H. pylori. The aim was to establish recommendations to guide healthcare providers in managing H. pylori in Saudi Arabia. Experts in the areas of H. pylori management and microbiology were invited to write these guidelines. A literature search was performed, and all authors participated in writing and reviewing the guidelines. In addition, international guidelines and consensus reports were reviewed to bridge the gap in knowledge when local and regional data were unavailable. There is limited local data on treatment of H. pylori. The rate of clarithromycin and metronidazole resistance is high; therefore, standard triple therapy for 10-14 days is no longer recommended in the treatment of H. pylori unless antimicrobial susceptibility testing was performed. Based on the available data, bismuth quadruple therapy for 10-14 days is considered the best first-line and second-line therapy. Culture and antimicrobial susceptibility testing should be considered following two treatment failures. These recommendations are intended to provide the most relevant evidence-based guidelines for the management of H. pylori infection in Saudi Arabia. The working group recommends further studies to explore more therapeutic options to eradicate H. pylori.

Comparable genetic alteration profiles between gastric cancers with current and past Helicobacter pylori infection. Sci Rep 2021; 11:23443. [PMID: 34873204 PMCID: PMC8648804 DOI: 10.1038/s41598-021-02761-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 11/23/2021] [Indexed: 11/09/2022] Open
Abstract
Gastric cancers can develop even after Helicobacter pylori (H. pylori) eradication in 0.2-2.9% cases per year. Since H. pylori is reported to directly activate or inactivate cancer-related pathways, molecular profiles of gastric cancers with current and past H. pylori infection may be different. Here, we aimed to analyze whether profiles of point mutation and gene amplification are different between the two groups. Current or past infection by H. pylori was determined by positive or negative amplification of H. pylori jhpr3 gene by PCR, and past infection was established by the presence of endoscopic atrophy. Among the 90 gastric cancers analyzed, 55 were with current infection, and 35 were with past infection. Target sequencing of 46 cancer-related genes revealed that 47 gastric cancers had 68 point mutations of 15 different genes, such as TP53 (36%), KRAS (4%), and PIK3CA (4%) and that gene amplification was present for ERBB2, KRAS, PIK3CA, and MET among the 26 genes assessed for copy number alterations. Gastric cancers with current and past infection had similar frequencies of TP53 mutations (38% and 31%, respectively; p = 0.652) and oncogene activation (20% and 29%, respectively; p = 0.444). Gastric cancers with current and past infection had comparable profiles of genetic alterations.

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

Abstract
BACKGROUND/PURPOSE Helicobacter pylori infection is one of the most common causes of peptic ulcer disease among children. This study is aimed to investigate the eradication rate of 14-day sequential therapy and the antibiotic resistance of H. pylori in children. METHODS Eighty-seven treatment-naïve children (55 males; median age, 13.5 years) with H. pylori infection from January 2009 to August 2019 were recruited in this study. The status of H. pylori infection was confirmed by culture or histology with the aid of urea rapid test or C-13 urea breathe test. Patients treated with either triple therapy for 7 days or 14 days, or sequential therapy for 14 days was analyzed retrospectively. RESULTS Thirty-eight (43.7%) patients received 14-day sequential therapy, 24 (27.6%) patients received 14-day triple therapy and the remaining 25 (28.7%) patients received 7-day triple therapy. The eradication rate of 14-day sequential therapy was significantly superior to 7-day triple therapy (97.4% vs. 80%, p = 0.032), and tended to be better than 14-day triple therapy (83%, p = 0.07). Of the 54 patients with available antibiotic resistance data, the resistant rate of clarithromycin, metronidazole, levofloxacin, and amoxicillin were 22.2%, 16.7%, 9.1% and 2.2%, respectively. Clarithromycin resistance demonstrated an inverse association with eradication success (Odds ratio = 0.017, p < 0.001). CONCLUSIONS In treatment-naïve children with H. pylori infection, 14-day sequential therapy is superior to triple therapy, and achieve a high eradication rate (above 90%) in an area of high clarithromycin resistance.

Efficacy and Cost-effectiveness Comparison of 10-Day, 14-Day Sequential Versus 14-Day Triple Therapies for Treating Helicobacter pylori Infection in Egyptian Patients. J Clin Gastroenterol 2020; 54:806-812. [PMID: 31904681 DOI: 10.1097/mcg.0000000000001278] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/14/2022]
Abstract
GOALS The aim of this study was to clarify whether 10-day or 14-day sequential therapy (ST) can replace conventional triple therapy (TT) as a first-line treatment in Egypt. BACKGROUND Antimicrobial resistance has decreased the eradication rates for Helicobacter pylori infection worldwide. MATERIALS AND METHODS Patients who tested positive for H. pylori infection were randomly assigned to the 14-day triple-therapy group (n=34), 10-day ST group (n=34), or 14-day ST group (n=35). Sequential treatment includes lansoprazole 30 mg and amoxicillin 1000 mg, both twice for 5 or 7 days, followed by lansoprazole 30 mg, clarithromycin 500 mg, and tinidazole 500 mg, each twice for 5 or 7 days. Triple treatment consists of lansoprazole 30 mg, clarithromycin 500 mg, and amoxicillin 1000 mg, each twice for 14 days. Six weeks after treatment discontinuation, patients were examined by the urea breath test. Eradication rates, the incidence of adverse effects, compliance, and cost-effectiveness were evaluated. RESULTS The eradication rate was 90% with 10-day ST, 96.7% with 14-day ST, and 63.3% for TT (P=0.001). Mild tolerated adverse effects occurred in the 3 groups. The cost-effectiveness ratio was 2194 LE, 1241 LE, 1157 LE for standard triple therapy, 10-day, and 14-day ST, respectively. CONCLUSIONS Sequential therapies for 10 or 14 days are more cost-effective than standard TT, with 14-day ST being the most cost-effective. Accordingly, ST might replace TT as a first-line treatment for H. pylori infection in Egyptian patients.

Efficacy and safety of 7 days versus 10 days triple therapy based on levofloxacin-dexlansoprazole for eradication of Helicobacter pylori: A pilot randomized trial. Indian J Pharmacol 2020; 52:356-364. [PMID: 33283766 PMCID: PMC8025764 DOI: 10.4103/ijp.ijp_364_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 11/01/2019] [Accepted: 10/12/2020] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Levofloxacin-based triple therapies are considered the standard regimen for eradication of Helicobacter pylori (H. pylori) due to decreased sensitivity to clarithromycin and the optimal duration of therapy is still controversial. Besides, there is no complete evidence about dexlansoprazole efficacy in the eradication of H. pylori. AIM Our study aimed to determine the effectiveness of triple therapy based on levofloxacin-dexlansoprazole as a standard treatment for H. pylori infection and estimate the effect of H. pylori on lipid profile and hemoglobin (Hb). MATERIALS AND METHODS A pilot prospective randomized trial of a triple therapy based on levofloxacin-dexlansoprazole for H. pylori eradication was conducted at Damanhour Medical National Institute, Egypt; 66 participants with H. pylori infection received levofloxacin (500 mg/day) plus amoxicillin (1 g/12 h) plus dexlansoprazole (60 mg/day). All medications administrated orally for either 7 days or 10 days. Four weeks after treatment, the eradication was assessed by the stool antigen test. RESULTS The rate of eradication was 63.6% in levofloxacin, amoxicillin, and dexlansoprazole (LAD) 7-day group, and 90.9% in LAD 10-day group. In addition, laboratory test results showed a significant difference in Hb, low-density lipoprotein, high-density lipoprotein, triglyceride, and total cholesterol levels before and after treatment (P < 0.05). CONCLUSION LAD 10 days is the least duration that provides maximum efficacy for H. pylori in Egyptian participants. In addition, successful treatment of H. pylori infection may reduce the risk of anemia and dyslipidemia. Furthermore, all members of the patient's family should be screened for H. pylori to prevent recurrent infection.

Abstract
The rising prevalence of antibiotic resistance and the long-term safety following eradication therapy are important issues in the management of Helicobacter pylori infection. The prevalence of clarithromycin, levofloxacin, and metronidazole resistance of H. pylori has increased to 21%, 27%, and 45%, respectively, in the Asia-Pacific region. Personalized treatment guided by susceptibility testing may provide a reliably excellent eradication rate in the first-line treatment but is costly and not widely available. Population-specific empirical therapy according to the local prevalence of antibiotic resistance may be an alternative strategy. Levofloxacin-based therapy and bismuth quadruple therapy are the recommended second-line rescue therapy. Susceptibility testing or genotypic resistance-guided therapy is the preferred treatment for refractory H. pylori infection, but empirical therapy may be an acceptable alternative. Eradication of H. pylori leads to short-term perturbation of gut microbiota. The diversity of gut microbiota can be restored months after eradication therapy, but the speed of recovery varies with regimens. The short-term increases of antibiotic resistance of Escherichia coli and Klebsiella pneumoniae may be restored to basal states months after H. pylori eradication. Future studies that apply in-depth sequencing, such as shotgun metagenomics sequencing, are needed to clarify whether the compositions of gut microbiota at the species level are fully restored.

Abstract
Acute upper gastrointestinal bleed (AUGIB) is one of the most common medical emergencies in the UK, with roughly one presentation every 6 min. Despite advances in therapeutics and endoscopy provision, mortality following AUGIB over the last two decades has remained high, with over 9,000 deaths annually in the UK; consequently, several national bodies have published UK-relevant guidelines. Despite this, the 2015 UK National Confidential Enquiry into Patient Outcome and Death in AUGIB highlighted variations in practice, raised concerns regarding suboptimal patient care and released a series of recommendations. This review paper incorporates the latest available evidence and UK-relevant guidelines to summarise the optimal pre-endoscopic, endoscopic, and post-endoscopic approach to and management of non-variceal and variceal AUGIB that will be of practical value to both general physicians and gastroenterologists.

Abstract
Sequential therapy has attracted increasing attention for cancer treatment, in which multiple drugs can be used to enhance the therapeutic efficacy. In this work, sequential therapy is demonstrated using amino functionalized Fe3O4 embedded periodic mesoporous organosilica spheres (Fe3O4@PMO-NH2) and Fe3O4@PMO as drug carriers. Losartan can inhibit type I collagen and hyaluronic acid of the pancreatic cancer matrix, which is safe and inexpensive, and does not increase the risk of tumor metastasis. First, losartan is loaded in the Fe3O4@PMO-NH2 (Fe3O4@PMO-NH2-Los) to treat pancreatic cancer. Immunohistochemistry staining of tumor slices after treatment with Fe3O4@PMO-NH2-Los confirms that collagen and hyaluronan acid are significantly reduced. The major solid components in the extracellular matrix of the tumor are reduced, which facilitates the penetration of nanodrugs into the tumor site. Afterward, gemcitabine loaded Fe3O4@PMO (Fe3O4@PMO-Gem) is sequentially delivered to treat pancreatic cancer, which shows strong killing ability for the pancreatic cancer cells. Comparing with a saline group, the tumor volume treated with Fe3O4@PMO-NH2-Los, Fe3O4@PMO-Gem, and Fe3O4@PMO-NH2-Los + Fe3O4@PMO-Gem decreases to 92.6%, 60.7%, and 28.6%, respectively, suggesting that the sequential therapy significantly inhibits pancreatic tumor growth compared to the mono-therapy strategy. Taken together, this study provides a promising approach for nanomaterials-based sequential therapy for pancreatic cancer treatment. Sequential therapy has attracted increasing attention for cancer treatment, in which multiple drugs can be used to enhance the therapeutic efficacy.![]()

Abstract
Helicobacter pylori (H. pylori) antimicrobial resistance is an urgent, global issue. In 2017, the World Health Organization designated clarithromycin-resistant H. pylori as a high priority bacterium for antibiotic research and development. In addition to clarithromycin, resistance to metronidazole and fluoroquinolones has also increased worldwide. Recent international guidelines for management of H. pylori infection recommend bismuth or non-bismuth quadruple therapy for 14 d as a first-line treatment for H. pylori in areas of high clarithromycin and/or metronidazole resistance. Although these treatment regimens provide acceptable H. pylori eradication rates, the regimens used should not contribute to future resistance of H. pylori to antimicrobials. Moreover, these regimens can promote resistance, due to prolonged therapy with multiple antibiotics. A new strategy that can eradicate H. pylori as well as reduce the antibiotics used is required to prevent future antimicrobial resistance in H. pylori. Dual-therapy with vonoprazan and amoxicillin could be a breakthrough for H. pylori eradication in an era of growing antimicrobial resistance. This regimen may provide a satisfactory eradication rate of H. pylori and also minimize antimicrobial resistance due to single antibiotic use and the strong inhibitory effect of vonoprazan on gastric acid secretion.

Abstract
BACKGROUND/AIMS The aim of the present study was to compare between the efficacy and tolerability of a sequential therapy (ST) as the first-line treatment for adults with Helicobacter pylori infection and that of standard triple therapy (TT). MATERIALS AND METHODS This was a prospective, randomized open-label, single-center study. We enrolled 206 patients who were divided into the following three treatment groups: Group A (pantoprazole 40 mg bid (twice daily), amoxicillin 1 g bid, and clarithromycin 500 mg bid for 10 d), Group B (the same TT as Group A for 14 d), and Group C (pantoprazole 40 mg bid and amoxicillin 1 g bid for 5 d, followed by pantoprazole 40 mg bid, clarithromycin 500 mg bid, and metronidazole 500 mg bid for additional 5 d). RESULTS Intention-to-treat (ITT) analysis revealed that 14 d of TT achieved a higher eradication rate than 10 d of ST (54.8% vs. 50.7%), but the difference was not statistically significant (p=0.623); further, 10 d of TT achieved 45% eradication rate. Per-protocol (PP) analysis revealed that the success rate for 10 d of ST was more than that for 10 d of TT (70.6% vs. 65%; p=0.571); however, the success rate for 10 d of TT was not statistically different from that for 14 d of TT. The eradication rates achieved in the ITT analysis were lower than those achieved in the PP analysis for 10 (45% vs. 65%) or 14 (54.7% vs. 69%) d of TT or for 10 d of ST (50.7% vs. 70.6%). No statistically significant difference was observed. Adverse effects and compliance were not significantly different among the three groups. CONCLUSION Neither 10 d of ST nor 14 d of TT achieved the optimum H. pylori eradication rate.

Abstract
In the face of rising prevalence of antibiotic resistance, susceptibility testing to provide personalized treatment is recommended prior to eradication therapy for Helicobacter pylori (H. pylori). Yet, population specific treatment according to the local prevalence of antibiotic resistance may be an alternative if susceptibility testing is not available. In this article, we reviewed the global prevalence of primary antibiotic resistance and the efficacies of commonly used regimens in antibiotic susceptible and resistance strains. We then constructed a model to predict the efficacies of these regimens and proposed an algorithm to choose the optimal first-line and rescue therapies according to the prevalence of antibiotic resistance. Clarithromycin-based therapy (triple, sequential, concomitant, and hybrid therapies) for 14 days remains the treatment of choice in regions with low clarithromycin resistance (≤15%) and bismuth quadruple therapy may be an alternative therapy. In regions with high clarithromycin resistance (> 15%), bismuth quadruple therapy is the treatment of choice and non-bismuth quadruple therapy may be an alternative. Either levofloxacin-based therapy or bismuth quadruple therapy may be used as second-line rescue therapy for patients fail after clarithromycin-based therapies, whereas levofloxacin-based therapy may be used for patients fail after bismuth quadruple therapy. Susceptibility testing or genotypic resistance should be determined after two or more eradication failures. However, empirical therapy according to prior medication history to avoid the empirical reuse of levofloxacin and clarithromycin may be an acceptable alternative after consideration of cost, patient preference, and accessibility. Rifabutin-based therapy for 14 days may serve as the fourth-line therapy. New antibiotics specific for H. pylori are highly anticipated.

Abstract
BACKGROUND Whether concomitant therapy is superior to triple therapy of various treatment lengths for the first-line treatment of H. pylori remains controversial. The objective of this study is to compare the efficacy of concomitant therapy and triple therapy given for 5-14 days. METHODS Randomized control trials (RCTs) comparing the efficacy of concomitant therapy for 5-14 days and proton pump inhibitor-amoxicillin-clarithromycin (PAC)-based triple therapy for 5-14 days in the first-line treatment of adult patients with H. pylori infection published from 1990 to January 2018 were searched from the PubMed, Cochrane Library, and Embase. Abstracts from international annual conferences were also searched. The primary and secondary outcomes were the eradication rate according to the intention-to-treat analysis and the adverse effects, respectively. Subgroup analyses were also performed according to treatment length. This study is registered with PROSPERO, number CRD42017081328. RESULTS Of the 639 articles identified, 23 RCTs including 3305 patients in the concomitant therapy group and 3327 patients in the triple therapy group were eligible. Overall, concomitant therapy was superior to triple therapy [risk ratio (RR): 1.15; 95% confidence interval (CI): 1.09-1.21; p < 0.001]. However, there were significant heterogeneity (I2 = 74.0%, p < 0.001). In the subgroup analysis, 5-day concomitant therapy was superior to 5-day triple therapy (RR: 1.30; 95% CI: 1.04-1.62; p = 0.02), 5- or 7-day concomitant therapy was superior to 7-day triple therapy (RR: 1.16; 95% CI: 1.12-1.21; p < 0.001), and 5- or 7-, or 10- or 14-day concomitant therapy was superior to 10-day triple therapy (RR: 1.15; 95% CI: 1.08-1.23; p < 0.001). However, 5- or 10-day concomitant therapy was not superior to 14-day triple therapy (RR: 1.02; 95% CI: 0.89-1.16; p = 0.796). The frequency of adverse effects was significantly higher in concomitant therapy than triple therapy (RR: 1.19; 95% CI: 1.06-1.34; P = 0.004). CONCLUSIONS Concomitant therapy given for 5 or 10 days was superior to 5- or 7-, or 10-day PAC-based triple therapy, but was not superior to 14-day triple therapy.

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.

Ji Y, Lu H. Meta-analysis: High-dose vs. low-dose metronidazole-containing therapies for Helicobacter pylori eradication treatment. PLoS One 2018; 13:e0189888. [PMID: 29370199 PMCID: PMC5784897 DOI: 10.1371/journal.pone.0189888] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Accepted: 12/04/2017] [Indexed: 01/06/2023] Open
Abstract
Objective The purpose of this study was to evaluate the efficacy of high dose of metronidazole in the treatment of Helicobacter pylori (H. pylori) infection. Methods Studies were identified from databases (Pubmed, Embase, Cochrane Library, ClinicalTrials.gov) searched from January 1990 to September 2017 using a battery of keywords. We included randomized controlled trials (RCTs) of H. pylori treatment comparing the high-dose and low-dose metronidazole-containing therapies (high-dose and low-dose therapies). Two reviewers independently selected studies, extracted relevant data and assessed study quality. A meta-analysis was performed by using Review Manager 5.3. Dichotomous data were pooled to obtain the relative risk (RR) of the eradication rate, with 95% confidence intervals (CIs). Results Four randomized controlled trials, a total of 612 patients with a diagnosis of H. pylori infection were included. Overall the meta-analysis showed that both high-dose and low-dose therapies achieved similar efficacy of intention-to-treat (ITT) eradication rate 82% vs. 76%, RR 1.12 (95%CI: 0.96 to 1.30), P = 0.15, and adherence 94% vs. 94%, RR 1.00 (95%CI: 0.97 to 1.04), P = 0.81, but side effects were more likely in high-dose therapies [32% vs. 17%, RR 1.84 (95%CI: 1.17 to 2.88), P = 0.008]. In subgroup analysis, increasing the dose of metronidazole enhanced eradication rates in areas with high metronidazole resistance [74% vs 52%, RR 1.40 (95%CI: 1.08 to 1.82), P = 0.01] and in individuals with metronidazole-resistant strains [71% vs. 46%, RR 1.50 (95%CI: 1.02 to 2.19), P = 0.04]. Conclusions Both high-dose and low-dose therapies can achieve similar eradication rates and adherence and generally low-dose therapies cause fewer side effects. In populations with high metronidazole resistance, high dose of metronidazole can increase the eradication rates of H. pylori infection.

Comparison between different first-line therapy protocols in eradicating Helicobacter pylori in a region with high clarithromycin resistance. GASTROENTEROLOGY REVIEW 2018; 13:150-156. [PMID: 30002775 PMCID: PMC6040106 DOI: 10.5114/pg.2018.72732] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/03/2017] [Accepted: 12/20/2017] [Indexed: 12/16/2022]
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 Several probiotics were effective in the eradication treatment for Helicobacter pylori (Hp), but their comparative efficacy was unknown. AIM To compare the efficacy of different probiotics when supplemented in Hp eradication therapy. METHODS A comprehensive search was conducted to identify all relevant studies in multiple databases and previous meta-analyses. Bayesian network meta-analysis was performed to combine direct and indirect evidence and estimate the relative effects. RESULTS One hundred and forty studies (44 English and 96 Chinese) were identified with a total of 20,215 patients, and more than 10 probiotic strategies were supplemented in Hp eradication therapy. The rates of eradication and adverse events were 84.1 and 14.4% in probiotic group, while 70.5 and 30.1% in the control group. In general, supplementary probiotics were effective in improving the efficacy of Hp eradication and decreasing the incidence of adverse events, despite of few ineffective subtypes. In triple eradication therapy, there was no significant difference among the effective probiotics, and combined probiotics did not show a better efficacy and tolerance than single use. In triple therapy of 7 days and 14 days, Lactobacillus acidopilus was a slightly better choice, while Saccharomyces boulardii was more applicable for 10-day triple therapy. CONCLUSIONS Compared to placebo, most probiotic strategies were effective when supplemented in Hp eradication therapy. In triple eradication therapy, no probiotic showed a superior efficacy to the others. Compared to single use, combined probiotics could not improve the efficacy or tolerance significantly.

Abstract
Gastric cancer and Helicobacter pylori infection remain a burden in many Asian countries. In the face of rising antibiotic resistance, the eradication rate of standard triple therapy is declining in many Asian countries. We reviewed the updated epidemiology of gastric cancer, prevalence of H. pylori infection, and antibiotic resistance in Asia. We also reviewed the strategies to improve the efficacy of H. pylori eradication therapies, including the use of high dose proton pump inhibitor, four drug therapies (including bismuth quadruple, concomitant, and sequential therapy), susceptibility guided therapy, extending the treatment duration to 14 days, and development of effective rescue therapy. Four drug therapies are usually more effective than triple therapy when given in the same duration, except in areas with concomitantly high metronidazole resistance and low clarithromycin resistance. The efficacies of different four drug regimens appeared to be similar. However, trials from different geographic areas showed contradictory results, indicating that the optimal therapy should be decided according to the local prevalence of antibiotic resistance. We proposed a prediction model to calculate the efficacy of different regimens according to the prevalence of antibiotic resistance. More large randomized trials which provide information on the antibiotic resistance are urgently needed to build a more accurate and reliable model. It is hoped that we will be able to decide the optimal regimens by routine surveillance of antibiotic resistance.

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.

Abstract
Helicobacter pylori infects about 50 % of the world's population, causing at a minimum chronic gastritis. A subset of infected patients will ultimately develop gastric or duodenal ulcer disease, gastric adenocarcinoma, or MALT (mucosa-associated lymphoid tissue) lymphoma. Eradication of H. pylori requires complex regimens that include acid suppression and multiple antibiotics. The efficacy of treatment using what were once considered standard regimens have declined in recent years, mainly due to widespread development of antibiotic resistance. Addition of bismuth to standard triple therapy regimens, use of alternate antibiotics, or development of alternative regimens using known therapies in novel combinations have improved treatment efficacy in specific populations, but overall success of eradication remains less than ideal. Novel regimens under investigation either in vivo or in vitro, involving increased acid suppression ideally with fewer antibiotics or development of non-antibiotic treatment targets, show promise for future therapy.

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
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.
