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

Novel Information Regarding the Treatment of Helicobacter pylori Infection: A Systematic Review and Meta-analysis of Randomized Clinical Trials. Curr Rev Clin Exp Pharmacol 2024; 19:184-203. [PMID: 36683319 DOI: 10.2174/2772432818666230120111237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 10/08/2022] [Accepted: 11/15/2022] [Indexed: 01/24/2023]
Abstract
OBJECTIVE Helicobacter pylori infects at least 50% of the world's human population. The current study aimed to assess and compare the efficacy of triple versus quadruple therapy. METHODS Randomized clinical trials (RCTs) consisting of triple and quadruple therapy were identified through electronic and manual searches in the national and international online databases (IsI, Magiran, Embase, PubMed, and Scopus). The random-effects model was applied to pool analysis. Funnel plots and the Egger test were used to examine publication bias. RESULTS After a detailed review of the selected articles, 80 RCTs were included in the meta-analysis; it was based on using triple and quadruple therapy as the first and second-line treatment. The results showed that quadruple therapy in the first-line treatment had a higher eradication rate than triple therapy. Overall, the eradication rate with triple therapy was 74% (95% CI, 71%-77%) for intention-totreat (ITT) analysis and 80% (95% CI, 77%-82%) for per-protocol (PP) analysis. Generally, the eradication rate with quadruple therapy was 82% (95% CI, 78.0%-86.0%) for ITT analysis and 85% (95% CI, 82.0%-89.0%) for PP analysis. The analysis also revealed that quadruple therapy was more effective for 7 or 10 days. CONCLUSION The current study results demonstrated that quadruple therapy has better effectiveness than triple therapy as the first-line treatment; however, in the second-line treatment, the effectiveness of quadruple and triple regimens is almost similar. The effectiveness of quadruple therapy in the Asian population was found to be slightly higher than that of triple therapy, while this difference was considerably higher in the European population.

Abstract
BACKGROUND With Helicobacter pylori's increasing antibiotic resistance, evidence of more effective treatments is lacking in China, where H. pylori prevalence is nearly 50%. Thus, we performed a network meta-analysis to compare therapeutic regimens. METHODS Data extracted from eligible randomized controlled trials from January 2000 to September 2021 were entered into a Bayesian hierarchical random-effects model to evaluate the efficacy and safety of H. pylori eradication regimens. RESULTS This study included 101 trials involving 21,745 patients. Vonoprazan-bismuth-containing quadruple therapy (VBQT) ranked the highest [surfaces under cumulative ranking curve (SUCRA), 83.64%], followed by high-dose amoxicillin dual therapy (HDDT) [SUCRA, 79.70%, odds ratio (OR)=1.31, 95% credible interval (CrI) (0.36, 4.72)] and proton pump inhibitor-based bismuth-containing quadruple therapy (BQT) [SUCRA, 63.59%, OR=1.59, 95% CrI (0.48, 5.24)]. HDDT [OR=2.47, 95% CrI (1.51, 4.06)], BQT [OR=2.04, 95% CrI (1.69, 2.47)], concomitant quadruple nonbismuth therapy (CT) [OR=1.93, 95% CrI (1.19, 3.15)], and sequential therapy (ST) [OR=1.86, 95% CrI (1.50, 2.32)] had higher eradication rates than standard triple therapy (TT). ST (SUCRA, 82.52%) and VBQT (SUCRA, 83.89%) had the highest eradication rate before and after 2010 in the effectiveness ranking, respectively. Furthermore, the H. pylori eradication rate of patients receiving 14-day BQT treatment was higher than that of 10-day BQT regimen [OR=2.55, 95% CI (1.84, 3.53)] and 7-day BQT regimen [OR=3.64, 95% CI (2.64, 5.01)]. CONCLUSIONS The TT regimen was not an optimal choice in China for H. pylori eradication; VBQT, HDDT, and BQT showed better efficacy. After 2010, there is a trend toward significance that VBQT provided a higher H. pylori eradication rate in China, but with only 1 randomized controlled trial. Thus, more supportive real-world data are needed to confirm its effectiveness.

Abstract
BACKGROUND AND AIM There is regional variation in the eradication rates of Helicobacter pylori (H. pylori) regimens depending on the local antibiotic resistance patterns. The aim of this study was to compare the efficacies of triple, quadruple and sequential antibiotic therapy in eradicating H. pylori infection. METHODS A total of 296 H. pylori-positive patients were randomized to receive one of the three regimens (triple, quadruple or sequential antibiotic therapy) and eradication rate was assessed by H. pylori stool antigen test. RESULTS The eradication rates of standard triple therapy, sequential therapy and quadruple therapy were 93%, 92.9% and 96.4%, respectively (p = 0.57). CONCLUSION Fourteen days of standard triple therapy, 14 days of bismuth-based quadruple therapy and 10 days of sequential therapy are equally efficacious in eradicating H. pylori and all regimens have optimum H. pylori eradication rates.

Abstract
BACKGROUND Helicobacter pylori ( H. pylori ) infection is an infectious disease with a prevalence rate of up to 50% worldwide. It can cause indigestion, gastritis, peptic ulcer, and gastric cancer. H. pylori eradication treatment can effectively control disease progression and reduce the risk of the above conditions. However, the escalating trend of antibiotic resistance presents a global challenge for H. pylori eradication. We aim to provide guidance on pharmacological treatment of H. pylori infection. METHODS This clinical practice guideline is developed following the World Health Organization's recommended process, adopting Grading of Recommendations Assessment, Development and Evaluation in assessing evidence quality, and utilizing Evidence to Decision framework to formulate clinical recommendations, minimizing bias and increasing transparency of the clinical practice guideline development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and The Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guides to ensure the guideline's completeness and transparency. RESULTS Though decreasing in developed countries, the prevalence of H. pylori remains high in developing countries, causing a major public health burden. This clinical practice guideline contains 12 recommendations concerning pharmacological treatment for H. pylori eradication. Among them, it is worth highlighting that bismuth preparations are inexpensive, safe, and effective, consequently making bismuth quadruple therapy a preferred choice for initial and rescue treatment. In empirical treatment, high-dose dual therapy is equally effective compared with bismuth quadruple therapy. CONCLUSIONS The 12 recommendations in this clinical practice guideline are formed with consideration for stakeholders' values and preferences, resource use, feasibility, and acceptability. Recommendations are generalizable to resource limited settings with similar antibiotic resistance pattern as China, and lower middle-income countries facing comparable sociological and technical challenges.

The Efficacy, Safety, and Tolerability of Levofloxacin Quadruple Therapy for Helicobacter pylori Eradication: A Randomized, Double-Blind Clinical Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9794901.

Abstract
The incidence of microbial resistance is growing, and new rescue regimens are needed to treat Helicobacter pylori (H. pylori) infection. This study aimed to evaluate levofloxacin-based quadruple therapies’ efficacy, safety, and tolerability in eradicating H. pylori. In a randomized, double-blind clinical trial, 220 patients with dyspepsia and H. pylori infection were randomly assigned to receive either bismuth subcitrate 240 mg, pantoprazole 20 mg, amoxicillin 1000 mg twice a day, and levofloxacin 500 mg daily for seven days (BPAL-7) or ten days (BPAL-10). The eradication of H. pylori was evaluated two months after the end of treatment, and adverse drug reactions (ADRs) were assessed during the intervention. According to intention-to-treat and per-protocol, the eradication rate was significantly lower in the BPAL-7 regimen at 49.1% (95% CI: 39.3–57.8) and 47.6% (95% CI: 39.7–58.4), respectively, compared to the BPAL-10 regimen at 62.7% (95% CI: 53.6–72.8) and 62.4% (95% CI: 55.1–72.8), respectively. The ADR incidence was not statistically significant between the groups of BPAL-7 (33.6%) and BPAL-10 (36.7%). Although the ADRs were negligible in both groups, these regimens could not be an ideal alternative therapy for H. pylori because of their low eradication rates compared to standard regimens. Trial Registration. The study was reviewed and approved by the Iranian Registry of Clinical Trials (IRCT201406141155N19).

Clinical Implications of Helicobacter pylori Antibiotic Resistance in Italy: A Review of the Literature. Antibiotics (Basel) 2022; 11:antibiotics11101452. [PMID: 36290110 PMCID: PMC9598780 DOI: 10.3390/antibiotics11101452] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/17/2022] [Accepted: 10/19/2022] [Indexed: 11/16/2022] Open
Abstract
Helicobacter pylori (H. pylori) resistance to antibiotics has increased worldwide in recent decades, especially to clarithromycin. As a result, the World Health Organization (WHO) identified clarithromycin-resistant H. pylori as a "high priority" pathogen in 2017. As international guidelines recommend empirical therapy as first-line treatment, it is crucial to know local resistance rates and history of antibiotic use to determine the most appropriate first-line antibiotic treatment. Italy is one of the European countries with the highest prevalence of H. pylori infection and the highest percentage of antibiotic-resistant H. pylori. The aim of this review is to summarize all data on H. pylori antibiotic resistance in Italy in order to quantify the current rate and determine the most effective therapeutic approach. The study confirms an elevated level of resistance to clarithromycin, metronidazole, and levofloxacin in Italy. In addition, our results show a satisfactory eradication rate for a bismuth-based regimen when used as first- or second-line treatment. Naive patients are also successfully treated with clarithromycin-based quadruple therapies. Considering the good results of bismuth-based therapy as recovery therapy, this argues for the potential use of clarithromycin quadruple therapy as a first-line treatment.

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.

Tetracycline-levofloxacin versus amoxicillin-levofloxacin quadruple therapies in the second-line treatment of Helicobacter pylori infection. Helicobacter 2021; 26:e12840. [PMID: 34390083 DOI: 10.1111/hel.12840] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/05/2021] [Accepted: 06/27/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND The Maastricht V/Florence Consensus Report recommends amoxicillin-fluoroquinolone triple or quadruple therapy as a second-line treatment for Helicobacter pylori infection. An important caveat of amoxicillin-fluoroquinolone rescue therapy is poor eradication efficacy in the presence of fluoroquinolone resistance. The study aimed to investigate the efficacies of tetracycline-levofloxacin (TL) quadruple therapy and amoxicillin-levofloxacin (AL) quadruple therapy in the second-line treatment of H. pylori infection. METHODS Consecutive H. pylori-infected subjects after the failure of first-line therapies were randomly allocated to receive either TL quadruple therapy (tetracycline 500 mg QID, levofloxacin 500 mg QD, esomeprazole 40 mg BID, and tripotassium dicitrato bismuthate 300 mg QID) or AL quadruple therapy (amoxicillin 500 mg QID, levofloxacin 500 mg QD, esomeprazole 40 mg BID, and tripotassium dicitrato bismuthate 300 mg QID) for 10 days. Post-treatment H. pylori status was assessed 6 weeks after the end of therapy. RESULTS The study was early terminated after an interim analysis. In the TL quadruple group, 50 out of 56 patients (89.3%) had successful eradication of H. pylori infection. Cure of H. pylori infection was achieved only in 39 of 52 patients (69.6%) receiving AL quadruple therapy. Intention-to-treat analysis showed that TL quadruple therapy achieved a markedly higher eradication rate than AL quadruple therapy (95% confidence interval: 4.8% to 34.6%; p = 0.010). Further analysis revealed that TL quadruple therapy had a high eradication rate for both levofloxacin-susceptible and resistant strains (100% and 88.9%). In contrast, AL quadruple therapy yielded a high eradication for levofloxacin-susceptible strains (90.9%) but a poor eradication efficacy for levofloxacin-resistant strains (50.0%). The two therapies exhibited comparable frequencies of adverse events (37.5% vs 21.4%) and drug adherence (98.2% vs 94.6%). CONCLUSIONS Ten-day TL quadruple therapy is more effective than AL quadruple therapy in the second-line treatment of H. pylori infection in a population with high levofloxacin resistance.

Comparative Effectiveness of Multiple Different First-Line Treatment Regimens for Helicobacter pylori Infection: A Network Meta-analysis. Gastroenterology 2021; 161:495-507.e4. [PMID: 33839101 DOI: 10.1053/j.gastro.2021.04.012] [Citation(s) in RCA: 74] [Impact Index Per Article: 24.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 03/27/2021] [Accepted: 04/05/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS A number of double, triple, and quadruple therapies have been proposed as first-line empiric treatments for Helicobacter pylori infection. However, knowledge of their worldwide and regional comparative efficacy is lacking. We examined the comparative effectiveness of all empirically used first-line regimens tested against standard triple treatment using a network meta-analysis of published randomized controlled trials. METHODS Data extracted from eligible randomized controlled trials were entered into a Bayesian network meta-analysis to investigate the comparative efficacy of H pylori infection empiric first-line regimens and to explore their effectiveness rank order. The ranking probability for each regimen was evaluated by means of surfaces under cumulative ranking values. RESULTS Sixty-eight eligible randomized controlled trials were included, giving a total of 92 paired comparisons with 22,975 patients randomized to 8 first-line regimens. The overall results showed that only vonoprazan triple therapy and reverse hybrid therapy achieved cure rates of >90%. Levofloxacin triple therapy performed best in Western countries (eradication rate 88.5%). The comparative effectiveness ranking showed that vonoprazan triple therapy had the best results, whereas standard triple therapy was the least efficacious regimen (surfaces under cumulative ranking 92.4% vs 4.7% respectively; odds ratio, 3.80; 95% credible interval, 1.62-8.94). CONCLUSIONS For first-line empiric treatment of H pylori infection, vonoprazan triple therapy and reverse hybrid therapy achieved high eradication rates of >90%. Levofloxacin triple therapy achieved the highest eradication rates in Western countries. Standard triple therapy was the least efficacious regimen in this network meta-analysis.

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 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
H. pylori infection is the main cause of gastritis, gastroduodenal ulcer disease, and gastric cancer. Fluoroquinolones such as levofloxacin, or more recently moxifloxacin or sitafloxacin, are efficacious alternatives to standard antibiotics for H. pylori eradication. The aim of the present review is to summarize the role of quinolone-based eradication therapies, mainly focusing on the optimization strategies aimed to increase their efficacy. Several meta-analyses have shown that, after failure of a first-line eradication treatment, a levofloxacin-containing rescue regimen is at least equally effective, and better tolerated, than the generally recommended bismuth quadruple regimen. Compliance with the levofloxacin regimens is excellent, and the safety profile is favourable. Higher cure rates have been reported with longer treatments (>10-14 days), and 500 mg levofloxacin daily is the recommended dose. Adding bismuth to the standard triple regimen (PPI-amoxicillin-levofloxacin) has been associated with encouraging results. Unfortunately, resistance to quinolones is easily acquired and is increasing in most countries, being associated with a decrease in the eradication rate of H. pylori. In summary, a quinolone (mainly levofloxacin)-containing regimen is an encouraging second-line (or even third-line) strategy, and a safe and simple alternative to bismuth quadruple therapy in patients whose previous H. pylori eradication therapy has failed.

Abstract
The optimal pharmacological regimen for eradication of Helicobacter pylori (H. pylori) has been investigated for many years. This study aimed to evaluate the efficacy and tolerability of bismuth-based quadruple therapy (B-QT) and a modified sequential therapy (ST) regimens in eradication of H. pylori. A randomized, double-blind trial was conducted on 344 patients. Patients with H. pylori infection and without a history of previous treatment were randomized to receive 14-day B-QT (bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily) or 14-day ST (bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and metronidazole 500 mg twice a day for seven days followed by bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and furazolidone 100 mg twice a day for additional seven days). Drug adverse effects were assessed during the study. H. pylori eradication was determined eight weeks after the end of treatment using 14C-urea breath test. Based on per-protocol and intention-to-treat, the eradication rate was significantly higher (p<0.05) in the B-QT regimen 91.9 % (95 % CI; 88.1-94.0) and 90.2 % (95 % CI; 86.3-92.9), respectively compared to the ST regimen 80.8 % (95 % CI; 76.6-84.9) and 78.1 % (95 % CI; 73.7-82.4), respectively. The severity of vomiting and loss of appetite were significantly higher in ST regimen (p<0.05). The B-QT regimen was more effective and safer than the ST regimen. Conclusively, it is suggested to assess the efficacy and safety of this regimen in longer studies, larger population, and in other communities.

Abstract
INTRODUCTION Helicobacter pylori infection is a common infection worldwide. The most frequently recommended treatment for eradication of H. pylori remains triple therapy. In this study, we compared sequential and hybrid regimens for H. pylori eradication in a region of Turkey with high resistance to clarithromycin. MATERIAL AND METHODS Three hundred and forty H. pylori-positive patients were enrolled in the study. The subjects were randomly divided into two groups. The first group (170 patients) received rabeprazole (40 mg/b.i.d.) and amoxicillin (1000 mg/b.i.d.) for 2 weeks and metronidazole and clarithromycin (500 mg/b.i.d.) during the second week in the hybrid therapy group. The second group (170 patients) received rabeprazole (40 mg/b.i.d.) for 14 days, amoxicillin (1000 mg/b.i.d.) for the first 7 days, and metronidazole plus clarithromycin (each 500 mg/b.i.d.) during the next 7 days in the sequential therapy group. RESULTS In the per-protocol analysis, the eradication rate in the hybrid therapy group was 96.1% (147/153), and in the sequential therapy group it was 90.9% (140/154). There was no significant difference between the two groups (p = 0.06). Ninety-seven of those 340 patients reported minor adverse drug reactions. The percentages of patients with adverse reactions were 30.6% in the hybrid therapy group and 26.5% in the sequential therapy group (p = 0.74). CONCLUSIONS Both therapies are highly effective for eradication of H. pylori, and could be recommended as a first-line therapy in regions with high antibiotic resistance.

Abstract
The effectiveness of standard triple therapy (STT) for the eradication of Helicobacter pylori has decreased recently. Sequential therapy (SQT) is a new regimen proposed to address this problem. The aim of this study was to compare the efficacy of SQT versus STT for H. pylori eradication. We searched The Cochrane Library, MEDLINE, Web of Science, and EMBASE databases up to July 2014. The risk ratios (RRs) of eradication rate were pooled, with a 95% confidence interval (CI). Thirty-six randomized clinical trials including a total of 10,316 patients met the inclusion criteria. The RR for eradication of H. pylori with SQT compared with STT was 1.14 (95% CI: 1.09-1.17), the eradication rates were 84.1% and 75.1%, respectively. There was significant heterogeneity between trial results (I = 73%; P < 0.00001). Subgroup analyses showed that SQT was superior to both 7- and 10-day STT, but not significantly better than 14-day STT. This superiority existed when patients were treated with either metronidazole or tinidazole. Patients with single clarithromycin-resistant strain showed a greater benefit of SQT over STT (eradication rates 80.9% vs. 40.7%), RR = 1.98 (95% CI: 1.33-2.94). There was no significant difference between groups in terms of the risk of adverse effects. In conclusion, SQT is more efficacious than STT (7 days and 10 days) in the eradication of HP, but the pooled rate seemed suboptimal. Further research is needed to develop more effective therapeutic approaches. Surveillance of resistance rates should be performed to guide treatment.

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.

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

Abstract
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
BACKGROUND The best rescue therapy for Helicobacter pylori (H. pylori) infection following failure of non-bismuth quadruple therapy (NBQT) remains unanswered. AIMS To determine the efficacy, safety and compliance of levofloxacin, bismuth, amoxicillin and esomeprazole (LBAE) regimen following failure of NBQT. METHODS 132 patients with H. pylori infection refractory to first-line NBQT received LBAE regimen (levofloxacin 500mg once/day, bismuth potassium citrate 220mg twice/day, amoxicillin 1000mg twice/day and esomeprazole 20mg twice/day for 14 days). Gastric mucosal biopsy was obtained for H. pylori culture, antimicrobial sensitivity test and cytochrome P450 isoenzyme 2C19 polymorphism analysis. RESULTS LBAE therapy achieved eradication rates of 73.5% [95% confidence intervals (CI) 65.9-81.1%] in intention-to-treat and 78.5% (71.1-85.9%) in per-protocol analyses in patients with high antibiotic resistance (amoxicillin 8.3%, clarithromycin 55.6%, metronidazole 73.6% and levofloxacin 36.1%). Adverse effects were found in 19.2% and compliance in 96.1% of the treated patients. Multivariate analyses identified levofloxacin resistance [odds ratio (OR) 7.183, 95% CI 1.616-31.914, P=0.010] and history of quinolone intake (4.844, 1.174-19.983, P=0.029) as independent predictors of treatment failure. The eradication rate of patients with dual amoxicillin and levofloxacin resistance was significantly decreased (33.3%, P=0.006). CONCLUSIONS In populations with high levofloxacin resistance, 14-day second-line LBAE regimen resulted in an unsatisfactory efficacy in patients resistant to NBQT despite good safety and compliance.

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
AIM: To evaluate the efficacy and safety of modified sequential therapy and to compare modified sequential therapy with standard quadruple therapy for Helicobacter pylori (H. pylori) eradication.
METHODS: In total, 200 consecutive patients who were diagnosed with H. pylori-infected chronic gastritis by electronic endoscopy and rapid urease testing from December 2012 to October 2013 were enrolled in this study. The patients had not previously received H. pylori eradication treatment, and were randomized into two groups. The patients in Group A (n = 101) were treated with ilaprazole + bismuth potassium citrate + amoxicillin and clavulanate potassium + levofloxacin, and the patients in Group B (n = 99) were administered a modified sequential therapy composed of ilaprazole at 5 mg bid and amoxicillin and clavulanate potassium at 914 mg for the first five days followed by ilaprazole at 5 mg bid, furazolidone at 100 mg bid and levofloxacin at 500 mg qid for the next five days. Four to six weeks after the end of treatment, a 14C-urea breath test was performed for all the subjects to confirm the eradication of H. pylori. The intention-to-treat and per-protocol eradication rates were determined.
RESULTS: A total of 190 of the 200 patients completed the study. All 200 patients were included in the intention-to-treat analysis, whereas 190 patients were included in the per-protocol analysis. In the intention-to-treat analysis, the rates of H. pylori eradication in Groups A and B were 85.15% (86/101) and 81.82% (81/99), respectively. In the per-protocol analysis, the H. pylori eradication rates in Groups A and B were 88.66% (86/97) and 87.09% (81/93), respectively. No significant difference was observed (χ2 = 0.109, P = 0.741) in the eradication rate between Groups A and B. The rates of adverse effects observed in the groups were similar at 6.19% (6/97) for Group A and 7.53% (7/93) for Group B (P > 0.05). No mortality or major morbidities were observed in any of the patients. Symptomatic improvements in the presentation of stomachache, acid regurgitation, and burning sensation were not significantly different between the two groups.
CONCLUSION: Ilaprazole-based 10-d standard quadruple therapy does not offer an incremental benefit over modified sequential therapy for the treatment of H. pylori infection, as both treatment regimens appear to be effective, safe, and well-tolerated as initial treatment options.

Abstract
BACKGROUND The most commonly used second-line Helicobacter pylori eradication regimens are bismuth-containing quadruple therapy and levofloxacin-containing triple therapy, both offering suboptimal results. Combining bismuth and levofloxacin may enhance the efficacy of rescue eradication regimens. AIMS To evaluate the efficacy and tolerability of a second-line quadruple regimen containing levofloxacin and bismuth in patients whose previous H. pylori eradication treatment failed. METHODS This was a prospective multicenter study including patients in whom a standard triple therapy (PPI-clarithromycin-amoxicillin) or a non-bismuth quadruple therapy (PPI-clarithromycin-amoxicillin-metronidazole, either sequential or concomitant) had failed. Esomeprazole (40 mg b.d.), amoxicillin (1 g b.d.), levofloxacin (500 mg o.d.) and bismuth (240 mg b.d.) was prescribed for 14 days. Eradication was confirmed by (13) C-urea breath test. Compliance was determined through questioning and recovery of empty medication envelopes. Incidence of adverse effects was evaluated by questionnaires. RESULTS 200 patients were included consecutively (mean age 47 years, 67% women, 13% ulcer). Previous failed therapy included: standard clarithromycin triple therapy (131 patients), sequential (32) and concomitant (37). A total of 96% took all medications correctly. Per-protocol and intention-to-treat eradication rates were 91.1% (95%CI = 87-95%) and 90% (95%CI = 86-94%). Cure rates were similar regardless of previous (failed) treatment or country of origin. Adverse effects were reported in 46% of patients, most commonly nausea (17%) and diarrhoea (16%); 3% were intense but none was serious. CONCLUSIONS Fourteen-day bismuth- and levofloxacin-containing quadruple therapy is an effective (≥90% cure rate), simple and safe second-line strategy in patients whose previous standard triple or non-bismuth quadruple (sequential or concomitant) therapies have failed.

AIM: To determine the efficacy of two quintuple regimens for eradication of Helicobacter pylori (H. pylori) in patients who failed previous therapies.
METHODS: This prospective, open-label, randomized controlled trial was a phase II study conducted from April 2011 to March 2012 at the Gastrointestinal and Liver Diseases Research Center in Rasht, Iran. A total of 208 patients with dyspepsia who failed previous H. pylori eradication with a ten-day quadruple therapy were enrolled. A random block method was used to assign patients to one of two treatment groups. Patients in the first group were treated with 240 mg bismuth subcitrate, 20 mg omeprazole, 1000 mg amoxicillin, 500 mg clarithromycin and 500 mg tinidazole (BOACT group). Patients in the second group received a regimen containing 240 mg bismuth subcitrate, 20 mg omeprazole, 500 mg tetracycline, 500 mg metronidazole and 200 mg ofloxacin (BOTMO group). Both regimens were given twice daily for a duration of seven days. The eradication was confirmed by a 14C urea breath test 12 wk after completion of therapy. Patient compliance and drug side effects were evaluated at the end of the treatment period. The success rates were calculated by intention-to-treat and per-protocol analyses.
RESULTS: A total of 205 patients completed the course of treatment, with three patients excluded due to drug intolerance. The mean age of patients did not differ between the BOACT and BOTMO groups (41.6 ± 12.2 years vs 39.6 ± 11.8 years), and no significant differences were found between the two groups in terms of age, sex, smoking habits or the initial eradication regimen. The intention-to-treat and per-protocol eradication rates were significantly higher in the BOTMO group (86.5%, 95%CI: 0.85-0.87 and 86.7%, 95%CI: 0.80-0.89, respectively) compared with the BOACT group (75.5%, 95%CI: 0.73-0.76 and 76%, 95%CI: 0.69-0.80, respectively) (P < 0.05). Univariate analyses for both groups did not show any association of sex, smoking and initial therapeutic regimen with eradiation rate (P > 0.05 for all). Significantly more patients experienced side effects in the BOACT group compared to the BOTMO group (77.4% vs 36.6%, P < 0.01). This difference was exemplified by increases in headache and taste disturbance (P < 0.05).
CONCLUSION: Quintuple therapy with a BOTMO regimen is an alternative second-line rescue therapy for Iranian patients with failed first-line eradication treatment of H. pylori.

Abstract
AIM To assess the efficacy and safety of standard triple therapy compared with other pre-existing and new therapies in China. METHODS Literature searches were conducted in the following databases: PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, the VIP database, the China National Knowledge Infrastructure database, and the Chinese Biomedical Database. A meta-analysis of all randomized controlled trials (RCTs) comparing standard triple therapy for the eradication of Helicobacter pylori with pre-existing and new therapies in China was performed using Comprehensive Meta-Analysis 2.0. There were 49 studies that met our criteria and the qualities of these studies were assessed using the Jadad scale. The Mantel-Haenszel method was used for pooling dichotomous data. We also conducted subgroup analyses according to age, duration of treatment and drug type. Sensitivity analyses and a cumulative meta-analysis were also performed with CMA 2.0. Publication bias was evaluated using Egger's test, Begg's test or a funnel plot. RESULTS A total of 49 RCTs including 8332 patients were assessed. This meta-analysis showed that standard triple therapy with proton pump inhibitors (PPIs), amoxicillin (AMO) and clarithromycin (CLA) was inferior to sequential therapy [relative risk (RR) = 0.863; 95% confidence interval (CI): 0.824-0.904], but was not superior to quadruple therapy (RR = 1.073; 95%CI: 0.849-1.357) or other triple therapies (RR = 1.01; 95%CI: 0.936-1.089). The meta-analysis also suggested that standard triple therapy is slightly more effective than dual therapy (RR = 1.14; 95%CI: 0.99-1.31). However, the differences were not statistically significant. We removed the only trial with a regimen lasting 14 d by sensitivity analysis and found that 7-d standard triple therapy was superior to 7-d dual therapy (RR = 1.222; 95%CI: 1.021-1.461). Moreover, a sub-analysis based on the duration of quadruple therapy indicated that the 7-d and 10-d standard triple therapies were inferior to sequential therapy (RR = 0.790; 95%CI: 0.718-0.868; RR = 0.917; 95%CI: 0.839-1.002, respectively). Additionally, there were no significant differences in cure rate or adverse events among standard triple therapy, quadruple therapy, and other triple therapies (RR = 0.940; 95%CI: 0.825-1.072; RR = 1.081; 95%CI: 0.848-1.378, respectively). Standard triple therapy had a higher occurrence of side effects than sequential therapy (RR = 1.283; 95%CI: 1.066-1.544). CONCLUSION The eradication rates with a standard triple therapy consisting of PPI, AMO, and CLA are suboptimal in China, and new treatment agents need to be developed.

Abstract
BACKGROUND Several studies have reported that the application of ecabet sodium during the eradication of Helicobacter pylori can improve the eradication rate and reduce therapy-associated side effects. However, the efficacy and safety of this therapy are controversial. OBJECTIVES To determine whether ecabet sodium improves the eradication rate of H. pylori and examine treatment safety by conducting a meta-analysis based on randomized controlled trials (RCTs). METHODS Literature searches were conducted in the following databases: PubMed, Embase, the Cochrane Library, the Science Citation Index, the China National Knowledge Infrastructure Database, and the Wanfang Database. A meta-analysis of all RCTs comparing ecabet sodium supplementation with nonecabet sodium-containing therapy was performed. RESULTS Thirteen RCTs that included a total of 1808 patients were assessed. The meta-analysis showed that the eradication rate in the ecabet sodium-containing quadruple therapy group was higher than that in the standard triple therapy group (84.5% vs 74.55%, OR 1.757 (95%CI: 1.307 to 2.362), p < .001). The analysis also showed that the eradication rate in the ecabet sodium-containing triple therapy group was significantly higher than that in the PPI plus amoxicillin or clarithromycin therapy group (74.6% vs 43.9%,OR 3.727 (95%CI: 2.320 to 5.988), p < .001)(ITT), (74.6% vs 43.9%,OR 3.863 (95%CI: 2.369 to 6.298), p < .001) (PP). Furthermore, our meta-analysis suggested that the occurrence of side effects did not significantly differ between patients receiving ecabet sodium-containing therapy and patients receiving nonecabet sodium-containing therapy (14.0% vs 13.3%, OR 1.055 (95%CI: 0.632 to 1.759), p = .839). CONCLUSION Supplementation with ecabet sodium during H. pylori eradication therapy improves the eradication rate. The use of ecabet sodium does not increase the side effects based on our meta-analysis.

Abstract
Sequential treatment scheme has been developed to overcome resistance problem in H. pylori eradication and favorable results have been obtained. This study compared the results of standard triple therapy with a sequential schema consisting of pantoprazole, amoxicillin, clarithromycin, and metronidazole in a high anti-microbial resistance setting. This retrospective study included subjects that underwent standard or sequential eradication treatment after a diagnosis of biopsy-documented H. pylori infection. Patients either received pantoprazole 40 mg bid, amoxicillin 1000 mg bid and clarithromycin 500 mg bid (PAC) for 10 days, or pantoprazole 40 mg bid and amoxicillin 1000 mg bid (PA) for the first 5 days of the treatment period and were then given pantoprazole 40 mg bid, clarithromycin 500 mg bid, and metronidazole 500 mg bid (PCM) in the remaining 5 days. Eradication was tested using urea breath test. The two treatment groups did not differ with regard to H. pylori eradication rate for both ITT population (63.9% versus 71.4% for standard and sequential therapy respectively, P = 0.278) and per protocol population (65.9% versus 74.1% for standard and sequential therapy respectively, P = 0.248). Although a sequential treatment appears to represent a plausible alternative, our findings suggest that alternative schedules may be required in certain populations to achieve higher success rates.

Abstract
AIM To evaluate the utility of the string test to detect genotypic clarithromycin-resistant Helicobacter pylori (H. pylori) by polymerase chain reaction (PCR)-restriction fragment length polymorphism. METHODS Patients undergoing endoscopic examinations were enrolled in the present study. String tests were done on the next day of endoscopy. Segments of 23S rRNA were amplified from DNA obtained from string tests. PCR-restriction fragment length polymorphism was accomplished by restriction enzymes BbsI and BsaI recognizing the mutation site A to G at 2143 or at 2142 of 23S rRNA domain V, respectively. RESULTS One hundred and thirty-four patients with H. pylori infection underwent string tests. To compare phenotypic resistance, 43 isolates were successfully cultured in 79 patients in whom 23S rRNA was successfully amplified. Of five patients with clarithromycin-resistant H. pylori, 23S rRNA of H. pylori isolates from four patients could be digested by BsaI. In 38 susceptible isolates, 23S rRNA of H. pylori isolates from 36 patients could not be digested by either BsaI or BbsI. The sensitivity and specificity of the string test to detect genotypic clarithromycin resistance were 66.7% and 97.3%, respectively. Positive and negative predictive values were 80% and 94.7%, respectively. CONCLUSION String test with molecular analysis is a less invasive method to detect genotypic resistance before treatment. Further large-scale investigations are necessary to confirm our results.

Sequential therapy or triple therapy for Helicobacter pylori infection in Asians: systematic review and meta-analysis. Clin Res Hepatol Gastroenterol 2014; 38:118-25. [PMID: 24238722 DOI: 10.1016/j.clinre.2013.10.001] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2013] [Revised: 09/25/2013] [Accepted: 10/10/2013] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND OBJECTIVE Eradication rate of Helicobacter pylori infection with triple therapy (TT) has declined in part to increased antibiotic resistance. Sequential therapy (ST) has shown promise in several meta-analyses. However, most of the studies included in previous meta-analyses were from Italy. The aim of this study was to compare the efficacy of ST with that of TT in Asia by performing a meta-analysis of studies from Asia. MATERIALS AND METHODS We performed a comprehensive literature search for studies comparing the efficacy of ST with TT. Randomised controlled trials investigated in the Asian population were included. The odds ratios (OR) of eradicating H. pylori infection after ST compared with TT were pooled. The eradication rates were considered both on an intention-to-treat (ITT) and on a per-protocol basis (PP). RESULTS A total of nine studies provided data on 3074 adult patients. The odds ratio (OR) for eradication of H. pylori with ST compared with TT was 1.768 (95% CI: 1.476-2.117, P=0.000) for ITT analysis and 1.997 (95% CI: 1.607-2.480, P=0.000) for PP analysis. The pooled eradication rates of ITT analysis was 81.3% (95% CI: 76.5-85.3) for the ST group and 70.8% (95% CI: 64.6-76.4) for the TT group. The pooled eradication rates of PP analysis was 87.6% (95% CI: 84.1-90.5) for the ST group and 77.1% (95% CI: 70.9-82.3) for the TT group. There was no difference in the rate of adverse events between ST and TT (OR 0.945, 95% CI: 0.874-1.238, P=0.658). CONCLUSION ST appears to be better than TT in the eradication of H. pylori in Asia. These results suggest that ST may be a reasonable choice for first line therapy in Asia.

Abstract
BACKGROUND Several alternative treatment regimens for Helicobacter pylori eradication have been proposed since the efficacy of standard triple therapy has declined over time, and sequential therapy is one of them. The purpose of this systematic review is to analyze and compare the efficacy, adverse effects and cost of sequential therapy with that of standard triple therapy for H. pylori infection. METHODS MEDLINE, EMBASE, Google Scholar and Cochrane databases were used to retrieve all relevant articles published in the English language over the last 5 years (January 2008-October 2012). Eligibility criteria were randomized controlled trials (RCTs) comparing sequential and standard triple therapies in patients with documented H. pylori infection. Eligibility and quality of the trials were assessed independently by two reviewers, and the data regarding eradication rate, adverse effects and the cost of therapy were extracted. RESULTS Of the 17 RCTs included in the analysis (Asia 13, Europe 3, Latin America, 1), 12 reported better eradication rates with the sequential therapy, four did not find a significant difference between the two treatment regimens, and one reported a better eradication rate with standard triple therapy. All except one RCT reported no significant difference in the incidence of adverse effects between standard triple therapy and sequential therapy. Sequential therapy was cheaper than standard triple therapy in all three RCTs where a cost analysis was performed. The limitations of the RCTs included in the systematic review were that the sequential therapy regimen and the duration of standard triple therapy were not uniform. Antibiotic susceptibility tests were performed in only three RCTs. CONCLUSIONS While the majority of the RCTs have shown superior eradication rates with sequential therapy, the largest RCT from Latin America did not find a significant difference between the two treatment regimens. Sequential therapy has good efficacy; however, further trials other than those from Asia and Italy are required to assess its superiority over existing regimens before recommending sequential therapy as the first line of treatment for H. pylori infection.

Abstract
BACKGROUND AND AIM Although several meta-analyses suggested that sequential therapy (SQT) is superior to standard triple therapy (STT) for the eradication of Helicobacter pylori, these results were mainly based on the studies from Italy. The aim of this study was to assess the efficacy of 10-day SQT for H. pylori infection compared with STT in Asian adults. METHODS We performed an electronic search of the Cochrane Library, Medline, and Embase up to April 21, 2013, with no language restrictions. Randomized controlled trials comparing 10-day SQT with STT for H. pylori eradication in Asian adults were included in this analysis. The primary outcome measures were the risk ratios (RRs) for successful eradication of H. pylori based on intention to treat comparing SQT with STT. The secondary outcome measures were the RRs for side effects. RESULTS Seventeen randomized controlled trials with a total of 3419 participants (1591 for SQT and 1828 for STT) met the inclusion criteria. The eradication rate was 81.8% (95% CI: 78.9-84.6) for SQT and 74.3% (95% CI: 69.6-78.8) for SST, respectively. The pooled RR was 1.10 (95% CI: 1.04-1.16, P = 0.0005), which demonstrated significant superiority of SQT over STT, and the number needed to treat was 14 (95% CI: 9-29). There were no significant differences between SQT and STT in the risk of side effects (the pooled RR: 0.98, 95% CI: 0.87-1.10, P = 0.73). CONCLUSION Ten-day SQT appears to be superior to STT for H. pylori eradication in Asian adults. However, the pooled efficacy is lower than results from earlier European studies.

Abstract
Antimicrobial resistance has continued to undermine many popular anti-Helicobacter pylori therapies. Antibiotic resistance to commonly used anti-H. pylori drugs in China has increased markedly, making China an ideal site to identify regimens that remain effective despite widespread antimicrobial resistance. Bismuth is one of the few antimicrobials to which resistance does not develop. Factors contributing to H. pylori treatment success include host factors (e.g., genetic differences in the metabolism of the drugs used), bacterial factors (e.g., susceptibility), and details of the regimen (e.g., doses, dosing interval, dosing in relation to meals, formulation, etc.). We reviewed the recent experience in China with bismuth-containing quadruple therapies. The experience consists of 16 studies with 25 arms involving 1971 patients to identify successful regimens (defined as reliably obtaining 90% or greater eradication per protocol) deserving further study. Despite high rates of resistance to commonly used antimicrobials, several regimens could achieve high success. These were characteristically 14-day regimens containing a proton pump inhibitor and either tetracycline and metronidazole or furazolidone and amoxicillin. We propose approaches for further development including for optimization and simplification related to convenience and side effects (e.g., twice rather than three or four times daily or administration at the noon and evening meal instead of at breakfast and evening) while maintaining effectiveness of at least 90%. Studies in China identified regimens that were highly effective despite the high prevalence of resistance to metronidazole, fluoroquinolones, and macrolides. Multicenter randomized studies will be required to confirm which is the best.

Abstract
OBJECTIVE The aim of this study was to assess and compare the efficacy and safety of sequential treatment with standard triple therapies in a located population in Morocco. METHODS Consecutive H. pylori-positive patients with endoscopy-proven ulcer or non ulcer dyspepsia were prospectively randomized in the trial into one of three groups: AM and AC group were administered a tri-therapy for 7 days including PPI + amoxicillin + metronidazole (AM group)/clarithromycin (AC group) and SQ group was administered a sequential regimen consisting of PPI + amoxicillin for 5 days followed by PPI + clarithromycin + metronidazole for the remaining 5 days. Eradication was confirmed by 13C-urea breath test 3 months after the end of the treatment. RESULTS Groups AM, AC and SQ included respectively 104, 115 and 104 patients. They were comparable in terms of age, sex, clinical and endoscopic presentation. The rate of H. pylori eradication with sequential therapy was found at 94.2% (n=98) in ITT and 96% (n=98) in PP. It was higher than those found in the AM group: 70% (n=73) in ITT and 70.8% (n=73) in PP and the AC group: 78.2% (n=90) in ITT and 79.6% (n=90) in PP (0.001). The prevalence of side effects following the sequential treatment was 9.6% (n=10) versus 22% (n=22) and 27.8% (n=32) in the AM and AC groups, respectively, (P=0.006). CONCLUSIONS Sequential treatment was better tolerated and achieved a significantly higher eradication rate of H. pylori compared with standard triple therapies in this population.

Abstract
OBJECTIVE To do a systematic review and meta-analysis of studies comparing sequential therapy for eradication of Helicobacter pylori with pre-existing and new therapies, thus providing a glimpse of eradication success worldwide. DESIGN Systematic review and meta-analysis. DATA SOURCES Medline, Embase, and Cochrane Central Register of Controlled Trials up to May 2013; abstract books of major European, American, and Asian gastroenterological meetings. STUDY SELECTION Randomised controlled trials in previously untreated adults, in which sequential therapy was compared with a pre-existing or new therapy. RESULTS 46 randomised controlled trials were reviewed and analysed. 5666 patients were randomised to sequential therapy and 7866 to other (established and new) treatments. The overall eradication rate of sequential therapy was 84.3% (95% confidence interval 82.1% to 86.4%). Sequential therapy was superior to seven day triple therapy (relative risk 1.21, 95% confidence interval 1.17 to 1.25; I(2)=29.3%; number needed to treat 6, 95% confidence interval 5% to 7%), marginally superior to 10 day triple therapy (1.11, 1.04 to 1.19; I(2)= 67.2%; NNT 10, 7 to 15), but not superior to 14 day triple therapy (1.00, 0.94 to 1.06; I(2)=54.3%), bismuth based therapy (1.01, 0.95 to 1.06; I(2)=21.1%), and non-bismuth based therapy (0.99, 0.94 to 1.05; I(2)=52.3%). Data on eradication according to pre-treatment antimicrobial susceptibility testing were available in eight studies, and sequential therapy was able to eradicate 72.8% (61.6% to 82.8%) of the strains resistant to clarithromycin. CONCLUSIONS Eradication rates with pre-existing and new therapies for H pylori are suboptimal. Regional monitoring of resistance rates should help to guide treatment, and new agents for treatment need to be developed.

Abstract
Signicant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

Abstract
H. pylori infection remains a worldwide spread disease with a definite morbidity and mortality. Unfortunately, no current therapy regimen is able to cure the infection in all treated patients. The efficacy of the widely recommended triple therapies is decreasing, and a novel 10-day sequential therapy has been proposed. Data of 3 previous meta-analyses showed a significantly higher eradication rate following the sequential as compared to the 7-10 days triple therapies. The sequential therapy achieved significantly better results than triple therapies in children, elderly patients, non-ulcer dyspepsia patients, and in those infected with resistant strains towards either clarithromycin or metronidazole. We identified further 10 randomized trials. By pooling data, H. pylori infection was cured in 2,454 (86%; 95% CI: 84.7-87.3) out of 2,853 patients with the sequential therapy and in 2,320 (75.3%; 95% CI: 73.8-76.9) out of 3,079 patients treated with standard triple therapies (p<0.001), corresponding to a number to treat (NNT) of 9. The comparison between the 10-day sequential regimen and 14-day triple therapies deserves further investigations.

Abstract
With the rising prevalence of antimicrobial resistance, the treatment success of standard triple therapy has recently declined to unacceptable levels (ie, 80% or less). Following the failure of conventional triple therapy, novel eradication regimens have been developed including sequential therapy, concomitant quadruple therapy, hybrid (dual-concomitant) therapy, bismuth-containing quadruple therapy, and a therapy with administration of N-acetylcysteine before a culture-guided antibiotic regimen. This article reviews the literature published on Helicobacter pylori eradication in the last year, focusing on the development of alternative strategies for first-, second-, and third-line rescue therapy for the eradication of H. pylori.

Abstract
With the rising prevalence of antimicrobial resistance, the eradication rates of Helicobacter pylori (H. pylori) with standard treatments are decreasing to unacceptable levels (i.e., ≤80%) in most countries. After these disappointing results, several authorities have proposed that infection with H. pylori should be approached and treated as any other bacterial infectious disease. This implicates that clinicians should prescribe empirical treatments yielding a per protocol eradication of at least 90%. In recent years several treatments producing ≥90% cure rates have been proposed including sequential therapy, concomitant quadruple therapy, hybrid (dual-concomitant) therapy, and bismuth-containing quadruple therapy. These treatments are likely to represent the recommended first-line treatments in the near future. In the present paper, we are considering a series of critical issues regarding currently available means and approaches for the management of H. pylori infection. Clinical needs and realistic endpoints are taken into account. Furthermore, emerging strategies for the eradication of H. pylori and the existing evidence of their clinical validation and widespread applicability are discussed.

Abstract
BACKGROUND Traditional standard triple therapy for Helicobacter pylori (H. pylori) infection (proton pump inhibitor-clarithromycin-amoxicillin) can easily be converted to non-bismuth quadruple (concomitant) therapy by the addition of a nitroimidazole twice daily. AIM To critically review evidence on the role of non-bismuth quadruple therapy (proton pump inhibitor-clarithromycin-amoxicillin-nitroimidazole) in the treatment of H. pylori infection. METHODS Bibliographical searches were performed in MEDLINE and relevant congresses up to December 2011. We performed a meta-analysis of the studies evaluating the concomitant therapy, and of the randomized controlled trials comparing the concomitant and the standard triple therapy. RESULTS A meta-analysis of 19 studies (2070 patients) revealed a mean H. pylori cure rate (intention-to-treat) of 88% (95% confidence interval from 85% to 91%) for non-bismuth quadruple therapy. We performed a meta-analysis of the randomized controlled studies comparing the concomitant (481 patients) and the standard triple therapy (503 patients). The former was more effective than the latter: 90% versus 78% (intention-to-treat analysis). Results were homogeneous (I(2) = 0%). The odds ratio for this comparison was 2.36 (95% confidence interval from 1.67 to 3.34). A tendency toward better results with longer treatments (7-10 days versus 3-5 days) has been observed, so it seems reasonable to recommend the length of treatment achieving the highest cure rates (10 days). Clarithromycin resistance may reduce the efficacy of non-bismuth quadruple therapy, although the decrease in eradication rates seems to be far lower than in standard triple therapy. Experience with the non-bismuth quadruple therapy in patients with metronidazole-resistant strains is still very limited. CONCLUSION Non-bismuth quadruple (concomitant) therapy appears to be an effective, safe, and well-tolerated alternative to triple therapy and is less complex than sequential therapy. Therefore, this regimen appears well suited for use in settings where the efficacy of triple therapy is unacceptably low.

Abstract
BACKGROUND Traditional standard triple therapy for Helicobacter pylori infection (PPI-clarithromycin-amoxicillin) can easily be converted to non-bismuth quadruple (concomitant) therapy by the addition of a nitroimidazole twice daily. AIM To critically review evidence on the role of non-bismuth quadruple therapy (PPI-clarithromycin-amoxicillin-nitroimidazole) in the treatment of H. pylori infection. METHODS Bibliographical searches were performed in MEDLINE and relevant congresses. RESULTS The first randomised comparison of the non-bismuth quadruple therapy and the sequential (PPI-amoxicillin 5days plus PPI-clarithromycin-nitroimidazole 5days) regimens recently concluded that both were similar in terms of efficacy and safety and that the sequential administration protocol may be unnecessarily complex. Several randomised controlled trials (and one meta-analysis) have demonstrated that non-bismuth quadruple therapy is more effective than and is equally well tolerated as standard triple therapy. A meta-analysis of 15 studies (1723 patients) revealed a mean H. pylori cure rate (intention-to-treat) of 90% for non-bismuth quadruple therapy. A tendency towards better results with longer treatments (7-10days vs. 3-5days) has been observed, so it seems reasonable to recommend the length of treatment by achieving maximal cure rates (10days). Clarithromycin resistance may reduce the efficacy of non-bismuth quadruple therapy, although the decrease in eradication rates seems to be far lower than in standard triple therapy.

CONCLUSIONS Non-bismuth quadruple (concomitant) therapy appears to be an effective, safe, and well-tolerated alternative to triple therapy and is less complex than sequential therapy.

Abstract
This article reviews the literature published pertaining to Helicobacter pylori eradication over the last year. The general perception among clinicians and academics engaged in research on H. pylori has been that eradication rates for first-line therapies are falling, although some data published this year have cast doubt on this. The studies published this year have therefore focussed on developing alternative strategies for the first-line eradication of H. pylori. In this regard, clear evidence now exists that both levofloxacin and bismuth are viable options for first-line therapy. The sequential and "concomitant" regimes have also been studied in new settings and may have a role in future algorithms also. In addition, data have emerged that the probiotic Saccharomyces boulardii may be a useful adjunct to antibiotic therapy. Other studies promote individualized therapies based on host polymorphisms, age, and other such demographic factors.

Abstract
BACKGROUND AND AIM The present study was designed to determine the eradication rate of 10 day sequential therapy in genotypic clarithromycin-resistant Helicobacter pylori group identified by molecular polymerase chain reaction (PCR) detection in Thai patients. METHODS Between May 2007 and June 2010, patients who had undergone gastroscopic examination at the King Chulalongkorn Memorial Hospital, for dyspeptic symptoms were recruited. Two biopsy samples from gastric antrum were obtained, one for rapid urease test and another for PCR. PCR-sequencing was performed to determine point mutations in 23S rRNA gene. Patients received 10 day sequential therapy consisting of lanzoprazole 30 mg and amoxicillin 1 g twice daily for 5 days followed by lanzoprazole 30 mg, clarithromycin 500 mg and nitroimidazole 500 mg twice daily for the remaining 5 days. Urea breath test (UBT) was performed to assess eradication therapy. RESULTS A total of 151 patients (mean age 52.7 years, 75 males and 76 females) were recruited in this study. All patients completed sequential therapy without significant side effects. Point mutations at A2143G and A2142G were detected in 17 patients (11.3%). Overall eradication rate was 94%. The eradication rate in the group with point mutation was significantly lower than the eradication rate in the group without point mutation (64.7% vs 97.8%; odds ratio = 19.6 and 95% confidence interval = 4.3-88.8; P < 0.0001). CONCLUSION Genotypic clarithromycin resistance was detected in only 11.3% of H. pylori infections in Thailand. Sequential therapy is highly effective in clarithromycin-sensitive but is less effective in clarithromycin-resistant H. pylori. PCR-molecular test could be a useful tool to identify antimicrobial resistance for optimizing an eradication regimen.
