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.

Abstract
Background/Aims Eradication of Helicobacter pylori infection with standard triple therapy (TT) has declined primarily because of increased antibiotic resistance. Sequential therapy (ST) has been suggested as an alternative to TT for the first-line treatment of H. pylori. The purpose of this study was to compare the efficacy of ST with TT. Methods This was a multicenter, randomized open-label trial performed at nine centers in Korea. Patients with H. pylori infection were randomly assigned to receive either 7 day TT or 10 day ST. Eradication rates, drug compliance, and adverse events were compared among the two regimens. Results A total of 601 patients were enrolled between March 2011 and September 2014. The intention-to-treat eradication rates were 70.8% for TT and 82.4% for ST (p=0.001). The corresponding per protocol eradication rates were 76.9% and 88.8% for TT and ST, respectively (p=0.000). There were no statistically significant differences between the two regimens with respect to drug compliance and adverse events. Conclusions ST achieved better eradication rates than TT as a first-line therapy for H. pylori eradication in Korea.

Systematic review with meta-analysis: the efficacy of levofloxacin triple therapy as the first- or second-line treatments of Helicobacter pylori infection. Aliment Pharmacol Ther 2016; 44:427-37. [PMID: 27363687 DOI: 10.1111/apt.13712] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2016] [Revised: 04/27/2016] [Accepted: 06/08/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND Levofloxacin triple therapy has been used for the first-line and second-line treatment of Helicobacter pylori infection for more than 10 years. AIMS To systematically review the efficacy of levofloxacin triple therapy in the first- and second-line treatment, and to assess the time trend and factors that might affect its efficacy. METHODS Prospective trials reporting the efficacy of levofloxacin triple therapy in either the first-line or second-line treatment of H. pylori infection in adults were searched from the PubMed and Cochrane database from January 2000 to September 2015. Meta-analysis was performed to calculate the cumulative eradication rate and the efficacies in subgroups. RESULTS Of the 322 articles identified, a total of 4574 patients from 41 trials, including 16 trials in the first-line treatment and 25 trials in the second-line treatment were eligible for analysis. The cumulative eradication rate was 77.3% (95% confidence intervals, CI: 74.7-79.6) and was 80.7% (95% CI 77.1-83.7) in the first-line treatment and 74.5% (95% CI: 70.9-77.8) in the second-line treatment. The efficacies of levofloxacin triple therapy before 2008, between 2009 and 2011, and after 2012 were 77.4%, 79.6% and 74.8% respectively. The eradication rate was higher when levofloxacin was given once daily (80.6%, 95% CI: 77.1-83.7) than twice daily (73.6%, 95% CI: 69.7-77.2). The efficacy was significantly higher in levofloxacin-susceptible strains than resistant strains (81.1% vs. 36.3%, risk ratio 2.18, 95% CI: 1.6-3, P < 0.001). CONCLUSION The efficacy of levofloxacin triple therapy has been lower than 80% in many countries and it is not recommended when the levofloxacin resistance is higher than 5-10%.

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
BACKGROUND Unsatisfactory Helicobacter pylori eradication rates and therapy-associated side effects remain a problem. AIM To update our 2010 meta-analysis on the effects of Saccharomyces boulardii as supplementation to a standard eradication regimen on H. pylori eradication rates and therapy-associated side effects. METHODS The Cochrane Library, MEDLINE and EMBASE databases were searched from July 2010 (end date of last search) to February 2015, with no language restrictions, for randomised controlled trials (RCTs); additional references were obtained from reviewed articles. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines. RESULTS Eleven RCTs (2200 participants, among them 330 children) met the inclusion criteria. Of the 853 patients in the S. boulardii group, 679 (80%, 95% CI 77-82) experienced eradication compared with 608 of the 855 patients (71%, 95% CI 68-74) in the control group [relative risk (RR) 1.11, 95% confidence interval (CI) 1.06-1.17; moderate quality evidence]. S. boulardii compared with control reduced the risk of overall H. pylori therapy-related adverse effects (RR 0.44, 95% CI 0.31-0.64; moderate quality evidence), particularly of diarrhoea (RR 0.51, 95% CI 0.42-0.62; high quality evidence) and nausea [RR 0.6, 95% CI 0.44-0.83 (moderate quality of evidence)]. CONCLUSIONS In the populations studied, the effectiveness of standard triple therapy was unsatisfactory. The addition of S. boulardii significantly increased the eradication rate, but it was still below the desired level of success. Saccharomyces boulardii significantly decreased some therapy-related side effects.

Abstract
BACKGROUND Empiric triple therapy for Helicobacter pylori should be abandoned when clarithromycin resistance rate is >15-20%. Optimisation of triple therapy (high-dose acid suppression and 14-day duration) can increase eradication rates by 10%. AIM To compare the efficacy and safety of optimised triple (OPT-TRI) and nonbismuth quadruple concomitant (OPT-CON) therapies. METHODS Prospective multicentre study in 16 Spanish centres using triple therapy in clinical practice. In a 3-month two-phase fashion, the first 402 patients received an OPT-TRI therapy [esomeprazole (40 mg b.d.), amoxicillin (1 g b.d) and clarithromycin (500 mg b.d) for 14 days] and the last 375 patients an OPT-CON treatment [OPT-TRI therapy plus metronidazole (500 mg b.d)]. RESULTS Seven-hundred seventy-seven consecutive patients were included (402 OPT-TRI, 375 OPT-CON). The OPT-CON therapy achieved significantly higher eradication rates in the per-protocol [82.3% (95% CI = 78-86%) vs. 93.8% (91-96%), P < 0.001] and intention-to-treat analysis [81.3% (78-86%) vs. 90.4% (87-93%), P < 0.001]. Adverse events (97% mild/moderate) were significantly more common with OPT-CON therapy (39% vs. 47%, P = 0.016), but full compliance with therapy was similar between groups (94% vs. 92%, P = 0.4). OPT-CON therapy was the only significant predictor of successful eradication (odds ratio, 2.24; 95% CI: 1.48-3.51, P < 0.001). The rate of participating centres achieving cure rates ≥ 90% favoured OPT-CON therapy (OPT-TRI 25% vs. OPT-CON 62%). CONCLUSIONS Empiric OPT-CON therapy achieved significantly higher cure rates (>90%) compared to OPT-TRI therapy. Addition of metronidazole to OPT-TRI therapy increased eradication rates by 10%, resulting in more mild adverse effects, but without impairing compliance with therapy.

Abstract
BACKGROUND The need for new effective Helicobacter pylori eradication therapy has focused efforts on the development and optimization of regimens with excellent eradication rates such as 14-day hybrid therapy. This study evaluated whether the duration of hybrid therapy could be reduced while maintaining a high eradication rate and to examine the effect of antibiotic resistance on outcome. MATERIALS AND METHODS Three separate multicenter pilot studies were carried out concurrently. To reduce selection bias, eligible subjects were randomized to 10-day, 12-day, or 14-day hybrid therapy consisting of esomeprazole 40 mg and amoxicillin 1 gm twice daily for 10, 12, or 14 days plus clarithromycin 500 mg, and metronidazole 500 mg twice daily for the final 7 days. The primary outcome was H. pylori eradication per-protocol assessed at least 8 weeks after therapy. RESULTS A total of 220 subjects were entered. The per-protocol analyses contained 60, 61, 61 subjects in the 10-, 12- and 14-day therapy studies, respectively. The eradication rates, per-protocol, were similar: 95% (95% confidence interval (CI); 89.5-100%) for 10-day, 95.1% (95% CI; 89.7-100%) for 12-day, and 93.4% (95% CI; 87.2-99.7%) for 14-day hybrid therapies. Antibiotic resistance was infrequent; however, all metronidazole or clarithromycin resistances were cured with 12- and 14-day therapies. CONCLUSION These results suggest that in regions of moderate to low clarithromycin and/or metronidazole resistance it may be feasible to shorten hybrid therapy to 10 or 12 days. Further study is needed to compare hybrid and concomitant therapy in regions with moderate-to-high clarithromycin and/or metronidazole resistance.

Abstract
BACKGROUND Studies have showed that 10-day sequential treatment regimen achieved higher Helicobacter pylori eradication rate than standard triple therapies. AIM To compare a 10-day sequential therapy and standard triple therapy in Chinese children with H. pylori infection. METHODS A prospective, multicentre, open-label, randomised controlled trial was conducted in four tertiary medical centres in China. Children with H. pylori gastritis were randomly assigned to a 10-day sequential therapy consisting of omeprazole and amoxicillin for 5 days followed by omeprazole, clarithromycin and metronidazole for the remaining 5 days, or 7-day or 10-day standard triple therapy comprising of omeprazole, amoxicillin and clarithromycin. H. pylori eradication was assessed by H. pylori stool antigen test. RESULTS A total of 360 patients were included. The eradication rate achieved with the 10-day sequential therapy was significantly higher than either the 7-day or 10-day standard triple treatment, either by the intention-to-treat analysis (81.4% vs. 61.9% or 67.7%, P < 0.05) or per-protocol analysis (89.7% vs. 70.8% or 77.8%, P < 0.05). CONCLUSIONS The 10-day sequential regimen was significantly more effective than standard 7-day or 10-day triple regimens in eradicating H. pylori infection in Chinese children.

Sierra F, Forero JD, Rey M, Botero ML, Cárdenas A. Pilot study: miscellaneous therapy is highly successful for Helicobacter pylori eradication. Aliment Pharmacol Ther 2013; 37:1165-71. [PMID: 23656465 DOI: 10.1111/apt.12329] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2013] [Revised: 03/10/2013] [Accepted: 04/16/2013] [Indexed: 02/06/2023]
Abstract
BACKGROUND Success in H. pylori eradication with conventional therapies has decreased to unacceptable levels (≤80%). New schemes of combined treatment are currently needed. AIM To test a miscellaneous therapy for H. pylori eradication. METHODS/PATIENTS Open-label, pilot, single-centre and prospective study. Patients received a 15-day treatment scheme that consisted of 5 initial days of lansoprazole 30 mg b.d., amoxicillin 1 g b.d., and metronidazole 500 mg t.d.s.; days 6 to 10: lansoprazole 30 mg q.d.s. and metronidazole 500 mg t.d.s.; days 11 to 15: lansoprazole 30 mg b.d., clarithromycin 500 mg b.d. and metronidazole 500 mg t.d.s. Each patient underwent an upper endoscopy before treatment and a second follow-up endoscopy at least 4 weeks after therapy. Success was defined on the basis of an eradication rate following a per-protocol analysis ≥95%. Biopsies before and after therapy were obtained for histological evaluation and rapid urease test. RESULTS One hundred and twenty-two patients were enrolled and 118 patients completed the study. The eradication rate for H. pylori with miscellaneous therapy was 94% (confidence Interval (CI) 95%, 90-98.3%) in the per-protocol analysis (PP) and 91% (95% CI, 86-96%) in the intention-to-treat (ITT) analysis. Adherence to treatment was 96% (113 patients). Among patients who completed treatment, 55% presented adverse events, mainly nausea and abdominal pain. CONCLUSION A miscellaneous therapy, based on the combination of multiple medications in high doses for 2 weeks, and with gastric pH elevation, is a highly effective treatment as a first-line therapy for the eradication of H. pylori.

Francesco VD, Zullo A, Hassan C. Is concomitant quadruple therapy for Helicobacter pylori eradication really needed for Japanese patients? World J Gastrointest Pharmacol Ther 2012; 3:103-4. [PMID: 23494655 PMCID: PMC3596515 DOI: 10.4292/wjgpt.v3.i6.103] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2012] [Revised: 09/20/2012] [Accepted: 11/20/2012] [Indexed: 02/06/2023] Open
Abstract
The study found that the 7 d of concomitant therapy (lansoprazole, amoxicillin, clarithromycin and metronidazole) achieved significantly higher eradication rates compared to 7 d of triple therapy (lansoprazole, amoxicillin, clarithromycin), the intention to treat (ITT) cure rates being 94.9% and 68.3%, respectively. According to our opinion, this study is clinically relevant for Japanese physicians for at least 2 reasons: (1) the standard triple therapy (clarithromycin plus amoxicillin) achieved disappointing cure rates in Japan - in agreement with what was observed in several countries; and (2) the concomitant quadruple therapy is an effective therapeutic alternative.

Abstract
BACKGROUND Problems with the standard triple treatment recommended for Helicobacter pylori eradication therapy include unsatisfactory (less than 80%) eradication rates among children. AIM To assess the evidence for sequential therapy compared with triple therapy on H. pylori eradication rates in children. METHODS The Cochrane Library, MEDLINE and EMBASE databases were searched in May 2012, with no language restrictions, as were abstracts from major gastroenterology conferences, for randomised controlled trials (RCTs) comparing sequential therapy with standard triple therapy for H. pylori eradication. Additional references were obtained from reviewed articles. Authors were contacted for extra information. Dichotomous data were pooled to obtain the relative risk (RR) of the eradication rate, with a 95% CI. RESULTS Ten RCTs involving a total of 857 children aged 3-18 years met the inclusion criteria. Of the 409 patients in the sequential therapy group, 318 (78%, 95% CI 73-82) experienced eradication compared with 314 of the 444 patients (71%, 95% CI 66-75) in the standard triple therapy group (RR 1.14, 95% CI 1.06-1.23, number needed to treat 15; fixed-effects model). Sequential therapy was superior to 7-day standard triple therapy, but was not significantly better than 10-day or 14-day triple therapy. There were no significant differences between groups in the risk of adverse effects. CONCLUSIONS The pooled evidence suggests that 10-day sequential therapy compared with standard triple therapy may be considered as an option for increasing the eradication rates in children; however, it is still less than desired.

High-dose rabeprazole-amoxicillin dual therapy and rabeprazole triple therapy with amoxicillin and levofloxacin for 2 weeks as first and second line rescue therapies for Helicobacter pylori treatment failures. Aliment Pharmacol Ther 2012; 35:1097-102. [PMID: 22404486 DOI: 10.1111/j.1365-2036.2012.05054.x] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2011] [Revised: 01/25/2012] [Accepted: 02/20/2012] [Indexed: 12/12/2022]
Abstract
BACKGROUND H. pylori eradication failures are difficult to treat and rescue therapies often consist of complex treatment regimens. AIM To determine an effective and practical rescue therapeutic strategy for H. pylori treatment failures using two consecutive regimens: first rescue therapy - rabeprazole 20 mg t.d.s. and amoxicillin 1 g t.d.s. for 2 weeks and for failures a further second rescue therapy - rabeprazole 20 mg b.d., levofloxacin 500 mg b.d., amoxicillin 1 g b.d. for a further 2 weeks. METHODS Consecutive patients who failed the proton pump inhibitor (PPI) 1-week triple therapy were recruited for the study. H. pylori status was determined by a C(13) urea breath test. RESULTS One hundred and forty-nine patients received the first rescue therapy. Seven were not compliant to medication/defaulted follow-up. Eradication success- first rescue therapy: per protocol (PP) analysis-107/142 (75.4%) (95% CI (68.3-82.4%) and intention to treat (ITT) analysis-107/149 (71.8%) 95% CI (64.6-79.0%). Thirty-one of 35 patients who failed the first rescue therapy received the second rescue therapy. All were compliant with medications. Eradication success- PP and ITT was 28/31 (90.3%) 95% CI (74.2-98.0%). The cumulative eradication rate using both rescue therapies: PP analysis- 135/138 (97.8%) 95% CI: (93.8-99.6%), ITT analysis- 135/149 (90.6%) 95% CI: (84.7-94.8%). CONCLUSIONS A 2-week high dose PPI-amoxicillin dual therapy followed by a PPI-amoxicillin-levofloxacin triple therapy were highly successful in achieving eradication in H. pylori treatment failures.
