Fekadu S, Engiso H, Seyfe S, Iizasa H, Godebo A, Deyno S, Yoshiyama H. Effectiveness of eradication therapy for Helicobacter pylori infection in Africa: a systematic review and meta-analysis. BMC Gastroenterol 2023; 23:55. [PMID: 36882697 PMCID: PMC9990047 DOI: 10.1186/s12876-023-02707-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 02/28/2023] [Indexed: 03/09/2023] Open
Abstract
BACKGROUND The effectiveness of Helicobacter pylori (H. pylori) eradication depends on the treatment protocol. This study investigates the H. pylori eradication rate in Africa using the best available evidence from databases. METHODS Databases were searched and results were pooled together. Heterogeneity between studies was assessed using I2 test statistics. Stata version 13 software was employed to compute the pooled eradication rate. In the subgroup analysis comparison, the finding is considered significant when the confidence intervals did not overlap. RESULTS Twenty-two studies from 9 African countries with a total population of 2,163 were included in this study. The pooled eradication rate of H. pylori was 79% (95% CI: 75%-82%), heterogeneity (I2 = 93.02%). In the subgroup analysis by study design, a higher eradication rate was reported from observational studies (85%, 95% CI: 79%-90%), compared to randomized control trials (77%, 95% CI: 73%-82%); by the duration of therapy, higher eradication rate was reported in 10-days regimen (88%, 95% CI: 84%-92%), compared to 7-days regimen (66%, 95% CI: 55%-77%); by country, the highest eradication rate was found in Ethiopia (90%; 95% CI: 87%-93%) and the lowest eradication rate was reported in Ivory Coast (22.3%; 95% CI:15%-29%); by type of H. pylori test, the highest eradication rate was reported when rapid urease test coupled with histology (88%, 95% CI: 77%-96%), and the lowest eradication rate was reported with histology alone (22.3%; 95% CI:15%-29%). Significant heterogeneity was observed with pooled prevalence (I2 = 93.02%, P < 0.000). CONCLUSIONS In Africa, the first-line therapy showed a variable eradication rate for H. pylori. This study demonstrates the necessity to optimize current H. pylori treatment regimens in each country, taking into account the antibiotic susceptibility. Future RCT studies with standardized regimens are warranted.

Nista EC, Pellegrino A, Giuli L, Candelli M, Schepis T, De Lucia SS, Ojetti V, Franceschi F, Gasbarrini A. Clinical Implications of Helicobacter pylori Antibiotic Resistance in Italy: A Review of the Literature. Antibiotics (Basel) 2022; 11:1452. [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 pyloriInfection is formally recognised as an infectious disease, an entity that is now included in the International Classification of Diseases 11th Revision. This in principle leads to the recommendation that all infected patients should receive treatment. In the context of the wide clinical spectrum associated with Helicobacter pylori gastritis, specific issues persist and require regular updates for optimised management.The identification of distinct clinical scenarios, proper testing and adoption of effective strategies for prevention of gastric cancer and other complications are addressed. H. pylori treatment is challenged by the continuously rising antibiotic resistance and demands for susceptibility testing with consideration of novel molecular technologies and careful selection of first line and rescue therapies. The role of H. pylori and antibiotic therapies and their impact on the gut microbiota are also considered.Progress made in the management of H. pylori infection is covered in the present sixth edition of the Maastricht/Florence 2021 Consensus Report, key aspects related to the clinical role of H. pylori infection were re-evaluated and updated. Forty-one experts from 29 countries representing a global community, examined the new data related to H. pylori infection in five working groups: (1) indications/associations, (2) diagnosis, (3) treatment, (4) prevention/gastric cancer and (5) H. pylori and the gut microbiota. The results of the individual working groups were presented for 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 various clinical fields.

Abstract
Helicobacter pylori infection is very common in the Spanish population and represents the main cause of chronic gastritis, peptic ulcer, and gastric cancer. The last iteration of Spanish consensus guidelines on H. pylori infection was conducted in 2016. Recent changes in therapeutic schemes along with increasing supporting evidence were key for developing the V Spanish Consensus Conference (May 2021). Fourteen experts performed a systematic review of the scientific evidence and developed a series of recommendations that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. An eradication therapy, when prescribed empirically, is considered acceptable when it reliably achieves, or preferably surpass, 90% cure rates. Currently, only quadruple therapies (with or without bismuth) and generally lasting 14 days, accomplish this goal in first- and second-line therapies. A non-bismuth quadruple concomitant regimen (proton pump inhibitor, clarithromycin, amoxicillin, and metronidazole) or a quadruple bismuth-based combination (proton pump inhibitor, bismuth, tetracycline, and metronidazole), are recommended as first-line regimens. Rescue therapies after eradication failure and management of H. pylori infection in peptic ulcer disease were also reviewed.

Abstract
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
BACKGROUND The occurrence of antibiotic-resistant strains has been rapidly increasing due to the wide use of antibiotics. To evaluate the current effects of antibiotic resistance on Helicobacter pylori eradication efficacy, we conducted this systematic review and meta-analysis. METHODS Literature searches were conducted in the following databases: PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Statistical analysis was performed using STATA version 12.0 (StataCorp LP, College Station, TX, USA). RESULTS A total of 120 studies, including 28 707 patients, were assessed. Only first-line therapy was considered. The pooled RR of eradication rate in patients with Helicobacter pylori strains sensitive versus resistant to clarithromycin was 0.682 (95% CI: 0.636-0.731). The pooled RR of eradication rate in patients with Helicobacter pylori strains sensitive versus resistant to metronidazole was 0.843 (95% CI: 0.810-0.877). The pooled RR of eradication rate in patients with Helicobacter pylori strains sensitive versus resistant to levofloxacin was 0.794 (95% CI: 0.669-0.941). The pooled RR of eradication rate in patients with Helicobacter pylori strains sensitive versus resistant to dual clarithromycin and metronidazole was 0.674 (95% CI: 0.590-0.770). CONCLUSION Antibiotic resistance causes a decrease in the eradication rate of H pylori today. Quadruple concomitant therapy may overcome the declining H pylori eradication rate caused by metronidazole-only resistance.

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

Abstract
Background: Helicobacter pylori (H. pylori) is important cause of peptic ulcer and gastric cancer. Moxifloxacin is
effective antibiotic for treatment for H. pylori. However, there were limited studies as first line therapy. Probiotics had been
shown to decrease therapy-related side-effect and increase eradication rate. Aim of this study was to evaluate the efficacy
of moxifloxacin-dexlansoprazole based triple therapy with probiotic for H. pylori treatment in Thailand. Methods:
Patients with H. pylori infected gastritis were randomized to receive 7- or 14-day moxifloxacin-dexlansoprazole based
triple therapy with probiotic or placebo. Regimen consisted of 60 mg dexlansoprazole twice daily, 400mg moxifloxacin
once daily, 1g clarithromycin MR once daily. Probiotic used in this study was 282.5mg Saccharomyces boulardii (S.
boulardii) in capsule prescribed twice daily. CYP2C19 genotyping, antibiotic susceptibility tests, and CagA genotyping
were also done. Successful eradication was defined as a negative 13C-urea breath test at least 4 weeks after treatment.
Results: Total of 108 subjects was enrolled (27 each to 7-and 14-day regimens with probiotic or placebo). Antibiotic
susceptibility tests showed 29% fluoroquinolone, 19% metronidazole and 4% clarithromycin resistance. CYP2C19
genotyping demonstrated 43%, 47% and 11% were rapid, intermediate and poor metabolizers, respectively. CagA
genes were positive in all patients. Eradication rates of 7-day and 14-day regimens with probiotic were 100%, and
93% respectively. There were no significant differences between eradication rate of 7-day and 14-day regimen with or
without probiotics. Regarding side-effects, incidence of nausea, abdominal discomfort, bitter taste, and diarrhea were
significantly lower in regimen with probiotic group compared with placebo(7.4%vs. 22.2%; p=0.028, 0.00%vs.14.8%;
p=0.003, 35.2%vs.70.4%; p=0.0002, and 0.00%vs.9.3%; p=0.028, respectively). Conclusions: 7-day moxifloxacindexlansoprazole
therapy plus S. boulardii provide an reliable cure rate of H. pylori in non-ulcer dyspeptic patients
in Thailand, independent of CYP2C19 genotype. Probiotic adding also decreased side effects during the treatment.

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

Abstract
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
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
BACKGROUND/AIMS Bismuth-containing quadruple and moxifloxacin-based triple regimens are recommended as second-line therapy for Helicobacter pylori infection. The aim of this study was to compare the efficacy of each regimen. METHODS From August 2004 to October 2012, a total of 949 patients (mean age, 54.32±12.08 years; male, 49.4%) who failed H. pylori eradication with a standard triple regimen were included. Patients treated with a bismuth-containing quadruple regimen for 7 and 14 days were designated as 7-BMT and 14-BMT, respectively, and those treated with a moxifloxacin-based triple regimen for 7 and 14 days were designated as 7-MA and 14-MA, respectively. H. pylori eradication was confirmed using the (13)C-urea breath test, rapid urease test or histology. RESULTS The eradication rates by 7-BMT, 14-BMT, 7-MA, and 14-MA were 66.4% (290/437), 71.1% (113/159), 53.1% (51/96), and 73.5% (189/257), respectively, by intention-to-treat analysis (ITT) and 76.5% (284/371), 83.8% (109/130), 55.6% (50/90), and 80.6% (187/232), respectively, by per-protocol analysis (PP). The eradication rates were higher in 14-BMT than 7-BMT by the ITT and PP analyses (p=0.277 and p=0.082, respectively). The 14-BMT and 14-MA treatments showed similar efficacies by ITT and PP (p=0.583 and p=0.443, respectively). CONCLUSIONS The 7-BMT, 14-BMT, and 14-MA treatments showed similar and suboptimal efficacies. In both regimens, extending the duration of treatment may be reasonable considering the high level of antibiotic resistance in Korea.

Severe gastritis decreases success rate of Helicobacter pylori eradication. Wien Klin Wochenschr 2015; 128:329-34.

Abstract
BACKGROUND In several studies, different risk factors other than antibiotic resistance have been documented with Helicobacter pylori eradication failure. We aimed in this study to investigate the relationship of gastric density of H. pylori, the occurrence/degree of gastric atrophy, and intestinal metaplasia (IM) with success rate of H. pylori eradication. METHODS Two hundred consecutive treatment naive patients who received bismuth containing standart quadruple treatment due to H. pylori infection documented by histopathological examination of two antral or two corpal biopsies entered this retrospective study. The updated Sydney system was used to grade the activity of gastritis, density of H. pylori colonization, atrophy, and IM. Stages III and IV of operative link for gastritis assessment (OLGA) or the operative link on gastric intestinal metaplasia assessment (OLGIM) stages was considered as severe gastritis. H. pylori eradication was determined via stool H. pylori antigen test performed 4 weeks after the end of therapy. RESULTS The presence of gastric atrophy and IM was significantly higher in patients with eradication failure (p = 0.001 and 0.01, respectively). Severe gastritis (OLGA III-IV and OLGIM III-IV) rates were higher in eradication failure group. A multiple linear regression analysis showed that OLGA and OLGIM stages were to be independent risk factors for eradication failure (p = 0.03 and 0.01, respectively). CONCLUSION Our results suggested that histopathologically severe gastritis may cause H. pylori eradication failure. In addition, we found that H. pylori density was not a risk factor for treatment failure in patients who receive quadruple treatment.

Abstract
AIM It is recommended that treatments that include clarithromycin should be avoided in eradication of Helicobacter pylori (HP) in cases where clarithromycin resistance is higher than 20%. We aimed to compare levofloxacin- and moxifloxacin-based triple therapies with standard treatment and with each other in eradication of helicobacter pylori as first-line therapy. MATERIALS AND METHODS Patients were randomized prospectively as three groups. There were 102 patients in the levofloxacin group, 101 patients in the moxifloxacin group, and 103 patients in the standard treatment group. The patients received levofloxacin 500 mg daily, amoxicillin 1 g b.i.d. and lansoprazole 30 mg b.i.d. for ten days (LAL) in the levofloxacin group; moxifloxacin 400 mg daily, amoxicillin 1 g b.i.d. and lansoprazole 30 mg b.i.d. (MAL) in the moxifloxacin group; and clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d. and lansoprazole 30 mg b.i.d. (CAL) in the standard treatment group. At post-treatment week 6, HP was checked by using stool antigen test. RESULTS In the eradication of Helicobacter pylori, the success rate as determined by per protocol (PP) analysis was 92% in the LAL group, 91.8% in the MAL group, and 82.4% in the CAL group. A statistically significant difference was found in the LAL and MAL groups compared to the CAL group (p < 0.05). There was no difference between the LAL and MAL groups. CONCLUSIONS It was determined that levofloxacin- and moxifloxacin-based triple therapies were more effective than the standard treatment in first-line setting in the eradication of Helicobacter pylori. In addition, no difference was found between levofloxacin- and moxifloxacin-based triple therapies. Currently observed high efficacy may be evaluated in treatment. Although quinolon resistance is not considered a major problem, it appears to be a factor that may reduce treatment success over a period of time.

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.

Abstract
BACKGROUND Aim was to evaluate the efficacy and tolerability of a moxifloxacin-containing second-line triple regimen in patients whose previous Helicobacter pylori eradication treatment failed. METHODS Prospective multicentre study including patients in whom a triple therapy or a non-bismuth-quadruple-therapy failed. Moxifloxacin (400mg qd), amoxicillin (1g bid), and esomeprazole (40 mg bid) were prescribed for 14 days. Eradication was confirmed by (13)C-urea-breath-test. Compliance was determined through questioning and recovery of empty medication envelopes. RESULTS 250 patients were consecutively included (mean age 48 ± 15 years, 11% with ulcer). Previous (failed) therapy included: standard triple (n = 179), sequential (n = 27), and concomitant (n = 44); 97% of patients took all medications, 4 were lost to follow-up. Intention-to-treat and per-protocol eradication rates were 82.4% (95% CI, 77-87%) and 85.7% (95% CI, 81-90%). Cure rates were similar independently of diagnosis (ulcer, 77%; dyspepsia, 82%) and previous treatment (standard triple, 83%; sequential, 89%; concomitant, 77%). At multivariate analysis, only age was associated with eradication (OR = 0.957; 95% CI, 0.933-0.981). Adverse events were reported in 25.2% of patients: diarrhoea (9.6%), abdominal pain (9.6%), and nausea (9.2%). CONCLUSION 14-day moxifloxacin-containing triple therapy is an effective and safe second-line strategy in patients whose previous standard triple therapy or non-bismuth quadruple (sequential or concomitant) therapy has failed, providing a simple alternative to bismuth quadruple regimen.

The efficacy of moxifloxacin-containing triple therapy after standard triple, sequential, or concomitant therapy failure for Helicobacter pylori eradication in Korea. Gut Liver 2014; 8:605-11. [PMID: 25368747 PMCID: PMC4215445 DOI: 10.5009/gnl13303] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2013] [Revised: 10/05/2013] [Accepted: 10/06/2013] [Indexed: 12/17/2022] Open
Abstract
Background/Aims Retreatment after initial treatment failure for Helicobacter pylori is very challenging. The purpose of this study was to evaluate the efficacies of moxifloxacin-containing triple and bismuth-containing quadruple therapy. Methods A total of 151 patients, who failed initial H. pylori treatment, were included in this retrospective cohort study. The initial regimens were standard triple, sequential, or concomitant therapy, and the efficacies of the two following second-line treatments were evaluated: 7-day moxifloxacin-containing triple therapy (rabeprazole 20 mg twice a day, amoxicillin 1,000 mg twice a day, and moxifloxacin 400 mg once daily) and 7-day bismuth-containing quadruple therapy (rabeprazole 20 mg twice a day, tetracycline 500 mg 4 times a day, metronidazole 500 mg 3 times a day, and tripotassium dicitrate bismuthate 300 mg 4 times a day). Results The overall eradication rates after moxifloxacin-containing triple therapy and bismuth-containing quadruple therapy were 69/110 (62.7%) and 32/41 (78%), respectively. Comparison of the two regimens was performed in the patients who failed standard triple therapy, and the results revealed eradication rates of 14/28 (50%) and 32/41 (78%), respectively (p=0.015). The frequency of noncompliance was not different between the two groups, and there were fewer adverse effects in the moxifloxacin-containing triple therapy group (2.8% vs 7.3%, p=0.204 and 25.7% vs 43.9%, p=0.031, respectively). Conclusions Moxifloxacin-containing triple therapy, a recommended second-line treatment for initial concomitant or sequential therapy failure, had insufficient efficacy.

Abstract
OBJECTIVE To compare the patients' compliance with and the efficacy of existing treatments for Helicobacter pylori eradication, including moxifloxacin-based triple therapy, sequential treatment and the standard treatment. METHODS Patients with H. pylori infection were randomly assigned to three therapy groups. The triple therapy (MML) group was given moxifloxacin 400 mg/day, metronidazole 500 mg b.i.d. and lansoprazole 30 mg b.i.d. for 10 days. The sequential treatment (AL-CML) group was administrated amoxicillin 1 g b.i.d. and lansoprazole 30 mg b.i.d. for the first 5 days, followed by clarithromycin 500 mg b.i.d., metronidazole 500 mg b.i.d. and lansoprazole 30 mg b.i.d. for the second 5 days. The standard treatment (CAL) group received amoxicillin 1 g b.i.d., clarithromycin 500 mg b.i.d. and lansoprazole 30 mg b.i.d. for 14 days. The eradication rates were evaluated by per-protocol (PP) analysis and intention-to-treat (ITT) analysis. RESULTS The eradication rates were 87.1, 85.9 and 85.2% by PP analysis and 87.1, 84.9 and 84.2% by ITT analysis in the MML, AL-CML and CAL group, respectively, and patients' compliance rates were 98.2, 96.5 and 97.1%, respectively. There were no significant differences in treatment efficacy and compliance rates in the MML, AL-CML and CAL groups (P > 0.05). CONCLUSIONS The present study revealed that standard triple therapy, sequential therapy and moxifloxacin-based triple therapy are all effective treatment regimens in terms of H. pylori eradication rates and compliance with therapy in Turkey.

Abstract
PURPOSE To determine the inclusion of women and the sex-stratification of results in moxifloxacin Clinical Trials (CTs), and to establish whether these CTs considered issues that specifically affect women, such as pregnancy and use of hormonal therapies. Previous publications about women's inclusion in CTs have not specifically studied therapeutic drugs. Although this type of drug is taken by men and women at a similar rate, adverse effects occur more frequently in the latter. METHODS We reviewed 158 published moxifloxacin trials on humans, retrieved from MedLine and the Cochrane Library (1998-2010), to determine whether they complied with the gender recommendations published by U.S. Food and Drug Administration Guideline. RESULTS Of a total of 80,417 subjects included in the moxifloxacin CTs, only 33.7% were women in phase I, in contrast to phase II, where women accounted for 45%, phase III, where they represented 38.3% and phase IV, where 51.3% were women. About 40.9% (n=52) of trials were stratified by sex and 15.3% (n=13) and 9% (n=7) provided data by sex on efficacy and adverse effects, respectively. We found little information about the influence of issues that specifically affect women. Only 3 of the 59 journals that published the moxifloxacin CTs stated that authors should stratify their results by sex. CONCLUSIONS Women are under-represented in the published moxifloxacin trials, and this trend is more marked in phase I, as they comprise a higher proportion in the other phases. Data by sex on efficacy and adverse effects are scarce in moxifloxacin trials. These facts, together with the lack of data on women-specific issues, suggest that the therapeutic drug moxifloxacin is only a partially evidence-based medicine.

The efficacy of moxifloxacin-based triple therapy in treatment of Helicobacter pylori infection: a systematic review and meta-analysis of randomized clinical trials. Braz J Med Biol Res 2013; 46:607-13. [PMID: 23903685 PMCID: PMC3859334 DOI: 10.1590/1414-431x20132817] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2012] [Accepted: 04/25/2013] [Indexed: 12/18/2022] Open
Abstract
Recent evidence shows that moxifloxacin could exert an antimicrobial effect
against Helicobacter pylori in both in vitro
and in vivo models. To systematically evaluate whether
moxifloxacin-containing triple therapy could improve eradication rates and
reduce side effects in first-line or second-line anti-H. pylori
treatment, eligible articles were identified by searches of electronic
databases. We included all randomized trials comparing moxifloxacin-based triple
therapy with standard triple or quadruple therapy during H.
pylori eradication treatment. Statistical analysis was performed
with Review Manager 5.0.10. Subanalysis/sensitivity analysis was also performed.
We identified seven randomized trials (n=1263). Pooled H.
pylori eradication rates were 79.03% (95%CI: 75.73-82.07) and
68.33% (95%CI: 64.44-72.04) for patients with moxifloxacin-based triple therapy
or with standard triple or quadruple therapy, respectively (intention-to-treat
analysis). The odds ratio (OR) was 1.82 (95%CI: 1.17-2.81), the occurrence of
total side effects was 15.23% (95%CI: 12.58-18.20) and 27.17% (95%CI:
23.64-30.92) for groups with or without moxifloxacin, and the summary OR was
0.45 (95%CI: 0.26-0.77). In subgroup analyses, we noted that the second-line
eradication rate in the moxifloxacin group was significantly higher than that in
the quadruple therapy group (73.33 vs 60.17%, OR: 1.78, 95%CI:
1.16-2.73, P<0.001). However, there was no difference in first-line
eradication treatment. Findings from this meta-analysis suggest that
moxifloxacin-based triple therapy is more effective and better tolerated than
standard triple or quadruple therapy. Therefore, a moxifloxacin-based triple
regimen should be used in the second-line treatment of H.
pylori infection.

Abstract
BACKGROUND Triple therapy with a proton pump inhibitor, moxifloxacin, and amoxicillin has been proven effective in first-line treatment of Helicobacter pylori infection. AIM To explore 1, the value of triple therapy with esomeprazole, moxifloxacin, and amoxicillin in second-line or rescue treatment of Caucasian patients and 2, the impact of treatment duration on eradication success. METHODS H. pylori-infected patients with at least one previous treatment failure were randomized to oral esomeprazole 20 mg b.i.d., moxifloxacin 400 mg o.d., and amoxicillin 1000 mg b.i.d. for either 7 (EMA-7) or 14 days (EMA-14). Eradication was confirmed by 13C urea breath test. Antimicrobial susceptibility testing was performed in all patients at baseline and in patients who failed treatment. RESULTS Eighty patients were randomized, and 60% had ≥ 2 previous treatment failures. Pretreatment resistance against clarithromycin and metronidazole was found in 70.5 and 61.5% of cases, respectively. The intention-to-treat eradication rate was significantly higher after EMA-14 compared with EMA-7 (95.0 vs 78.9%, p = .036). No independent risk factor for treatment failure could be identified. There were no serious adverse events. Five of the EMA-14 patients (12.5%) compared with none of the EMA-7 patients discontinued prematurely because of adverse events (p = .031). Post-treatment resistance against moxifloxacin was found in one of seven patients with isolated organisms (14.3%). CONCLUSION Second-line/rescue H. pylori eradication therapy with esomeprazole, moxifloxacin, and amoxicillin is very effective and well tolerated. Fourteen days of treatment significantly increase the eradication rate but also the rate of adverse events.

Abstract
BACKGROUND Moxifloxacin-containing triple therapy has been suggested as an alternative second-line therapy for Helicobacter pylori infection. AIMS To systematically review the efficacy and tolerance of moxifloxacin-containing triple therapy in second-line H. pylori eradication, and to conduct a meta-analysis of studies comparing this regimen with bismuth-containing quadruple therapy. MATERIALS AND METHODS Electronic databases including Medline, Embase, Cochrane controlled trials register, Web of Science, PubMed, Chinese Biomedical Literature Database (updated to December 2010), and manual searches were conducted. A meta-analysis of all randomized controlled trials (RCTs) comparing moxifloxacin-containing triple therapy to bismuth-containing quadruple therapy in the second-line treatment of H. pylori infection was performed. RESULTS Seven RCTs including 787 patients were assessed. The meta-analysis showed that the eradication rate in the moxifloxacin group was significantly higher than that in the quadruple therapy group (74.9 vs 61.4%, OR 1.89, 95% CI: 1.38-2.58, p < .0001); besides, the rates of side effects and discontinuing therapy because of side effects in the moxifloxacin group were significantly lower than those in the quadruple therapy group (side effects: 10.1 vs 27.8%, OR 0.27, 95% CI: 0.18-0.41, p < .00001; discontinuing therapy because of side effects: 1.4 vs 8.2%, OR 0.18, 95% CI: 0.08-0.40, p < .0001). These results were constant in the sensitivity analyses. CONCLUSION Moxifloxacin-containing triple regimen is more effective and better tolerated than the bismuth-containing quadruple therapy in the second-line treatment of H. pylori infection.

Abstract
New generations of fluoroquinolones, like levofloxacin and moxifloxacin, exhibit a broad-spectrum activity against Gram-positive and Gram-negative bacteria, and have been successfully introduced into the treatment of Helicobacter pylori infection. Based on a large body of evidence, current guidelines recommend the use of levofloxacin- or moxifloxacin-containing proton-pump inhibitor (PPI) triple therapies in second-line or rescue treatment of H. pylori infection. The efficacy of standard PPI triple therapies has substantially declined during the last decade, mainly due to increasing resistance against the key antibiotics clarithromycin and metronidazole. Therefore, alternative strategies for first-line therapy of H. pylori infection have been evaluated in a considerable number of clinical trials including sequential regimens, nonbismuth quadruple regimens, and quinolone-containing PPI triple therapy regimens. The aim of this paper is to summarize the current body of evidence of levofloxacin- and moxifloxacin-containing regimens in first-line treatment of H. pylori infection, and to discuss the risks and benefits of these strategies in the light of increasing resistance of H. pylori to quinolones.

Abstract
Introduction Antibiotic resistance decreases success of Helicobacter pylori (Hp) eradication. Recently published results show low rate of resistance and better compliance with moxifloxacin based regiments. Aims&methods Whether 7 days moxifloxacin with lansoprasole and amoxycillin can be compared with 10 days moxifloxacin with lansoprasole and amoxycillin according to moxifloxacin resistance. Patients with non-ulcer dyspepsia who had culture and histology positive Hp infection (n = 150) were randomly assigned into two groups. The first group (n = 75) received moxifloxacin 400 mg/d during 7 days and the other (n = 75) received moxifloxacin 400 mg/d during 10 days. All patients received amoxycillin 1 g twice daily, lansoprasole 30 mg twice daily. All Hp cultures were tested for sensitivity to moxifloxacin. Results 138 patients (92%) completed the study, 68 in the first group and 70 in the second. Eradication rates were 84% (57/68) and 76% (57/75) in the 7 days moxifloxacin group and 90% and 84% in the second group (63/70, 63/75) according to the PP and ITT analysis; p = n.s. Among 129 patients (86% of study group), 6% of strains were primary resistant to moxifloxacin. Eradication of moxifloxacin sensitive/resistant strains was 98%/66%, p < 0.05 Conclusion According to our results we recommend 7 days moxiflixacin based triple therapy.

Abstract
UNLABELLED Moxifloxacin has been used in the first-line treatment of Helicobacter pylori infection. The optimal dosage and duration have not been assessed. AIM To evaluate the effectiveness of moxifloxacin, amoxicillin and esomeprazole in four regimens, in previously untreated patients infected by H. pylori. METHODS AND PATIENTS Patients were randomly assigned to: esomeprazole 20 mg b.i.d., amoxicillin 1g b.i.d., and one of each of the four following dosages of moxifloxacin: moxifloxacin 400 mg b.i.d. for 10 days (EAM800x10), moxifloxacin 400 mg b.i.d. for 7 days (EAM800x7), moxifloxacin 400 mg b.i.d. for 5 days (EAM800x5), moxifloxacin 400 mg o.i.d. for 10 days (EAM400x10). Eradication was assessed by the Urea Breath Test (UBT) 2 months following the end of therapy. RESULTS Ninety-four, 102, 92 and 105 patients were recruited in EAM800x10, EAM800x7, EAM800x5, and EAM400x10 respectively. The eradication rate was for Intention-To-Treat (ITT) and Per Protocol (PP) analyses: EAM800x10 group ITT: 90.4%, PP: 94.4%; EAM800x7 group ITT: 80.3%, PP: 86.3%; EAM800x5 group ITT: 71.4%, PP: 75.2%; EAM400x10 group ITT: 80.0%, PP 84.8%. A statistically significant difference was reached between EAM800x10 vs. EAM800x7 (ITT and PP: P<0.05), and between EAM800x10 vs. EAM800x5 (ITT and PP: P<0.01) and vs. EAM400x10 (ITT: P<0.05; PP: P<0.04). Thirty patients treated unsuccessfully with EAM800x5 and EAM400x10 were re-treated with EAM800x10 with an eradication rate of 86.7% (ITT) and 92.2% (PP). Nineteen patients with positive UBT after EAM800x10 and EAM800x7 underwent a second-line rifabutin-based therapy with an eradication rate of 84.2% (ITT and PP). CONCLUSION A triple therapy with 800 mg of moxifloxacin a day for 10 days is more effective than the same treatment for 5 or 7 days and a treatment with 400mg of moxifloxacin a day for 10 days for the first-line eradication of H. pylori infection. The high cost of moxifloxacin-based treatment however, may limit its wide use as first-line treatment of H. pylori infection.

Abstract
BACKGROUND AND AIM The aim of this study was to evaluate the efficacy of a moxifloxacin-containing triple therapy as second-line treatment for Helicobacter pylori infection. We also investigated the effect of treatment duration and antibiotic resistance on the eradication rate of this therapy. METHODS We prospectively enrolled patients found to have persistent H. pylori infections after failure of first-line proton-pump inhibitor-based triple therapy. Patients took moxifloxacin (400 mg q.d.), amoxicillin (1000 mg b.i.d.), and esomeprazole (20 mg b.i.d.). The eradication rate, drug compliance, and adverse event rates were evaluated. Minimal inhibitory tests were performed for moxifloxacin and amoxicillin by the agar dilution method. RESULTS In 2004, 41 patients were treated for 7 days. The intention-to-treat and per-protocol eradication rates (ITT/PP) were 75.6/83.8%. Moxifloxacin resistance was 5.6%. Therapy was extended to 10 days during 2005-2006 and 139 patients were treated. The ITT/PP eradication rates were 71.9/82.6%; moxifloxacin resistance had increased to 12%. The final group of 181 patients in 2007-2008 who were treated for 14 days also had low eradication rates (68/79.9%), but there was no statistical significance in the efficacy among the treatment periods. Moxifloxacin resistance in 2007-2008 was 28.2%. Side-effect increased with treatment duration (i.e., 9.8, 12.2, and 25.4% at 7, 10, and 14 days, respectively, p = .001). CONCLUSION The 7-day moxifloxacin-containing triple therapy produced an unacceptably low eradication rate. Increasing the duration of therapy was expected to increase the eradication rate, but the expected increased did not materialize, most likely because of coincident marked increase in the prevalence of resistance to moxifloxacin. Tailored treatment based on antibiotic susceptibility testing might be more effective in the achievement of high eradication rate when rapid antibiotic resistance such as moxifloxacin is occurring.

Abstract
Until now, it has been unclear how proton pump inhibitors (PPIs) support Helicobacter pylori therapy. We tested whether the PPI omeprazole acts on the spatial orientation of H. pylori in the gastric mucus of infected Mongolian gerbils. Following repetitive PPI administration once daily but not following single doses or administration every 8 h, the bacterial spatial distribution changed, indicating a loss of orientation. Therefore, the therapeutic scheme of PPI administration may affect efficiency of treatment.

Abstract
BACKGROUND In eradication of Helicobacter pylori infection, standard quadruple second-line therapy consisting of proton pump inhibitor (PPI), bismuth, metronidazole and tetracycline often fails and shows poor patient compliance. The aim of our study was to evaluate the efficacy and tolerability of moxifloxacin-based triple therapy as an alternative second-line protocol. METHODS A total of 160 patients, in whom the initial standard PPI triple therapy had failed to eradicate H. pylori infection, were included in the study. The initial H. pylori status was assessed using the (13)C-urea breath test. Patients were randomized to one of the following 7-day treatment regimens: (1) OMM: omeprazole 20 mg twice a day, moxifloxacin 400 mg/day, metronidazole 500 mg three times a day; and (2) OBMT: omeprazole 20 mg twice a day, colloidal bismuth subcitrate 120 mg four times a day, metronidazole 500 mg three times a day, tetracycline 500 mg four times a day. Patient compliance and adverse events were evaluated one week after completion of therapy. H. pylori status was re-assessed with the (13)C-urea breath test six weeks after the end of therapy. RESULTS The eradication rates were 73.2% (60/82) and 78.9% (60/76) with moxifloxacin-based triple therapy, and 53.8% (42/78) and 64.6% (42/65) with bismuth-based quadruple therapy, by intention-to-treat (p = 0.018) and per-protocol (p = 0.088) analyses, respectively. Adverse events/intolerability were described in 12/82 patients in the OMM group and 18/78 patients in the OBMT group. Compliance with treatment was 92.7% in the OMM group and 83.3% in the OBMT group. CONCLUSION Moxifloxacin-based triple therapy is a highly effective second-line eradication treatment in H. pylori infection. Because of its high levels of safety and tolerability, this protocol represents an adequate alternative to the standard bismuth-based quadruple therapy.

Abstract
BACKGROUND Moxifloxacin-based triple therapy has been suggested as an alternative first line therapy to clarithromycin-based triple therapy for Helicobacter pylori infection. AIMS To systematically review the efficacy and tolerance of moxifloxacin-based triple therapy, and to conduct a meta-analysis of studies comparing this regimen with clarithromycin-based triple therapy. METHODS A search of The Cochrane Library, PUBMED, EMBASE, EBM Review databases, Science Citation Index Expanded, and CMB (Chinese Biomedical Literature Database) was performed. Randomized controlled trials comparing moxifloxacin-based triple therapy to gold standard triple therapy in the first-line treatment of Helicobacter pylori infection were selected for meta-analysis. Relative risk was used as a measure of the effect of the two above-mentioned regimens with a fixed-effects model using the methods of DerSimonian and Laird. RESULTS Four randomized controlled trials totaling 772 patients were included. The meta-analysis showed that the mean eradication rate was 84.1 (318/378) in the moxifloxacin-based triple therapy group and 73.6 (290/394) in the clarithromycin-based triple therapy group; there was statistical significance between the two groups (RR, 1.13; 95% CI, 1.01, 1.27; P=0.04). There were no statistically significant difference in the overall side effects (RR, 0.61; 95% CI, 0.25, 1.48; P<0.28). CONCLUSIONS Moxifloxacin-based triple therapy is more effective and does not increase the incidence of overall side effects compared to clarithromycin-based triple therapy in the treatment of H. pylori infection.

Abstract
AIM: To compare the H pylori eradication rates of two 7-day moxifloxacin-based therapies.
METHODS: In this parallel control study, 52 H pylori-positive patients were divided into EMT (esomeprazole 20 mg bid, moxifloxacin 0.4 g qd, tinidazole 0.5 g bid) group and RMA (ranitidine bismuth citrate capsules 0.4 g bid, moxifloxacin 0.4 g qd, amoxicillin 1.0 g bid) group. The patients in both groups were treated for 7 d. H pylori status was assessed 4 weeks after the end of treatment by 13C urea breath test.
RESULTS: The treatment was completed in all the 52 patients. The rates of H pylori eradication in group EMT and RMA were 83.3% and 79.4%, respectively, and there was no difference between them (χ2 = 0.117, P = 0.521).
CONCLUSION: Seven-day moxifloxacin-based triple therapy is a feasible H pylori eradication regimen.
