Abstract
Helicobacter pylori infection is an important issue worldwide, and several guidelines have been published for clinicians to achieve successful eradication. However, there are still some patients who remain infected with H. pylori after treatment. Clinicians should identify the reasons that caused treatment failure and find strategies to manage them. We have searched and organized the literature and developed methods to overcome factors that contribute to prior treatment failure, such as poor compliance, inadequate intragastric acid suppression, and antibiotic resistance. To improve compliance, telemedicine or smartphone applications might play a role in the modern world by increasing doctor-patient relationships, while concomitant probiotics could be administered to reduce adverse effects and enhance adherence. For better acid suppression, high-potency and high-dose proton-pump inhibitors or potassium-competitive acid blockers have preferable efficacy. To overcome antibiotic resistance, susceptibility tests either by culture or by genotyping are the most commonly used methods and have been suggested for antibiotic selection before rescue therapy, but empirical therapy according to detailed medical history could be an alternative. Eradication with a longer treatment period (14 days) has a better outcome than shorter period (7 or 10 days). Ultimately, clinicians should select antibiotics based on the patient's history of drug allergy, previous antibiotic exposure, local antibiotic resistance, available medications, and cost. In addition, identifying patients with a high risk of cancer and shared decision-making are also essential for those who have experienced eradication failure.

Abstract
The treatment of refractory Helicobacter pylori remains challenging in clinical practice. Factors that should be considered in the treatment of refractory H. pylori infection include treatment length, dosage of antibiotics and proton pump inhibitors (PPIs), number of drugs, and the selection of appropriate antibiotics. Extending the treatment length of triple therapy and non-bismuth quadruple therapy to 14 days may increase the eradication rate compared with a shorter period (7 or 10 days). The use of a higher dose of PPIs or vonoprazan may also increase the efficacy of triple therapy. Four-drug therapy, including bismuth or non-bismuth quadruple therapies, usually achieve higher eradication rates than triple therapy. The addition of bismuth or metronidazole to levofloxacin-amoxicillin-PPI therapy may also increase the eradication rate. Therefore, four-drug therapies containing a higher dose of PPIs for 14 days are recommended in the third-line treatment setting for refractory H. pylori infection. The selection of appropriate antibiotics may be guided by susceptibility testing or empirically by medication history. Tailored therapy guided by susceptibility testing or genotypic resistance is recommended whenever possible. However, properly designed empirical therapy based on prior medication history (i.e., avoid the reuse of clarithromycin or levofloxacin empirically) is an acceptable alternative to tailored therapy after considering accessibility, cost, and the preference of the patient.

Abstract
BACKGROUND AND AIM Guidelines for selecting the eradication regimen for Helicobacter pylori reinfection remain unclear. This study aimed to evaluate the eradication rate of H. pylori reinfection in patients with a previous infection successfully eradicated with index triple therapy. METHODS This was a single-center, retrospective case-control study. A total of 10 468 H. pylori-infected patients treated with proton-pump inhibitor-based triple eradication therapy at a tertiary medical institution between 2005 and 2016 were enrolled. We reviewed the medical records of the enrolled patients and compared the treatment outcomes in those with H. pylori reinfection after a successful eradication. RESULTS Helicobacter pylori infection was successfully eradicated with the index triple therapy in 7770 patients (74.2%). Among 3567 patients followed up for > 1 year, H. pylori reinfection occurred in 420 (11.8%; 3.06% per person-year) during a median follow-up of 39.1 months (interquartile range, 23.5-58.7 months). Of these patients, 164 received eradication therapy for reinfection (triple therapy in 102 and quadruple therapy in 62) and had follow-up data. Triple therapy showed an eradication rate of 78.4% for H. pylori reinfection, which was not significantly different from that of the index triple therapy (P = 0.394). Quadruple therapy for reinfection exhibited a better eradication rate (87.1%) than triple therapy but without statistical significance (P = 0.237). CONCLUSIONS Retreatment with triple therapy for H. pylori reinfection after successful eradication of prior infection showed comparable outcomes to the index triple therapy. Bismuth-containing quadruple therapy for reinfection tended to have a better eradication rate than did triple therapy.

Abstract
BACKGROUND Helicobacter pylori antibiotic resistance is an increasing problem worldwide. Pylera® may be an option as salvage therapy. AIM To assess the effectiveness, safety, and tolerance of Pylera® as a third-line in clinical practice. MATERIALS AND METHODS This was a multicenter, observational, prospective database study in four Spanish hospitals. Consecutive H. pylori-infected individuals treated with Pylera® and a proton-pump inhibitor (PPI) were invited to participate if they had failed to respond to PPI-clarithromycin-amoxicillin as first-line and to levofloxacin-amoxicillin-PPI as second-line therapy. Eradication was tested 4-8 weeks after Pylera® using a C13 -urea breath test. Treatment-related adverse effects (TRAEs) were assessed through a questionnaire and by reviewing databases. A questionnaire on patient satisfaction was completed in the last visit. RESULTS Of 103 subjects fulfilling the selection criteria, 101 were included in the intention-to-treat (ITT) analysis and 97 in the per-protocol (PP) analysis. A 10 day course was prescribed in all patients. Esomeprazole 40 mg b.i.d. was the most used PPI regimen (ITT=94.1%). Ninety-seven individuals (ITT=96.04%) completed more than 90% of the treatment. Overall eradication rates were ITT=80.2% (95% confidence interval [CI]: 72.3%-88.1%) and PP=84.4% (95% CI: 76.8%-91.8%). One or more TRAEs were experienced by 67.3% (95% CI: 57.7%-75.7%), all mild or moderate. TRAEs and the number of pills were the main complaints. CONCLUSION In an area of high antibiotic resistance to H. pylori, 10-day Pylera® plus double-dose PPI emerged as an alternative as third-line therapy, although not achieving optimal eradication rates. TRAEs were common but were neither severe nor did they condition compliance.

Abstract
Helicobacter pylori (H. pylori) infection is a common worldwide infection that is an important cause of peptic ulcer disease and gastric cancer. H. pylori may also have a role in uninvestigated and functional dyspepsia, ulcer risk in patients taking low-dose aspirin or starting therapy with a non-steroidal anti-inflammatory medication, unexplained iron deficiency anemia, and idiopathic thrombocytopenic purpura. While choosing a treatment regimen for H. pylori, patients should be asked about previous antibiotic exposure and this information should be incorporated into the decision-making process. For first-line treatment, clarithromycin triple therapy should be confined to patients with no previous history of macrolide exposure who reside in areas where clarithromycin resistance amongst H. pylori isolates is known to be low. Most patients will be better served by first-line treatment with bismuth quadruple therapy or concomitant therapy consisting of a PPI, clarithromycin, amoxicillin, and metronidazole. When first-line therapy fails, a salvage regimen should avoid antibiotics that were previously used. If a patient received a first-line treatment containing clarithromycin, bismuth quadruple therapy or levofloxacin salvage regimens are the preferred treatment options. If a patient received first-line bismuth quadruple therapy, clarithromycin or levofloxacin-containing salvage regimens are the preferred treatment options. Details regarding the drugs, doses and durations of the recommended and suggested first-line and salvage regimens can be found in the guideline.

Abstract
BACKGROUND The efficacy of proton-pump inhibitor-amoxicillin-clarithromycin therapy for H. pylori eradication has decreased over time. OBJECTIVE We assessed the trend of H. pylori eradication rates over the last 10 years and the relationship between the eradication rates and the amount of macrolide antibiotic use in a country with a high prevalence of H. pylori infection. METHODS This vast nationwide multicenter study was conducted with 34,139 adults treated for H. pylori infection from January 2001 to December 2010. The defined daily dose per km(2) (DSD) of macrolide antibiotics was calculated (n = 141,019) using the Health Insurance Review & Assessment data base from 2008 to 2010 in the two cities which had the lowest (Jeju city) or highest (Chuncheon city) eradication rate. RESULTS The eradication rates of proton-pump inhibitor-amoxicillin-clarithromycin therapy ranged 84.9-87.5% from 2001 to 2007, and those of 2008 to 2010 ranged 80.0-81.4% with a decreasing trend (p < 0.0001). The decreasing trend of eradication rates for the overall first-line therapy was observed only in three of the seven geographic areas in Korea (p < 0.0001). The DSD of macrolide antibiotics was significantly higher in Jeju than Cheunchon city (0.85 vs 0.52, p < 0.0001). CONCLUSIONS H. pylori eradication rates with clarithromycin-containing triple therapy in Korea showed a decreasing trend over the past 10 years, although the trend varied among geographic areas. This difference may be associated with the amount of macrolide antibiotic use.

Abstract
BACKGROUND & AIMS Helicobacter pylori infection is increasingly difficult to treat. The purpose of these consensus statements is to provide a review of the literature and specific, updated recommendations for eradication therapy in adults. METHODS A systematic literature search identified studies on H pylori treatment. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an online platform, finalized, and voted on by an international working group of specialists chosen by the Canadian Association of Gastroenterology. RESULTS Because of increasing failure of therapy, the consensus group strongly recommends that all H pylori eradication regimens now be given for 14 days. Recommended first-line strategies include concomitant nonbismuth quadruple therapy (proton pump inhibitor [PPI] + amoxicillin + metronidazole + clarithromycin [PAMC]) and traditional bismuth quadruple therapy (PPI + bismuth + metronidazole + tetracycline [PBMT]). PPI triple therapy (PPI + clarithromycin + either amoxicillin or metronidazole) is restricted to areas with known low clarithromycin resistance or high eradication success with these regimens. Recommended rescue therapies include PBMT and levofloxacin-containing therapy (PPI + amoxicillin + levofloxacin). Rifabutin regimens should be restricted to patients who have failed to respond to at least 3 prior options. CONCLUSIONS Optimal treatment of H pylori infection requires careful attention to local antibiotic resistance and eradication patterns. The quadruple therapies PAMC or PBMT should play a more prominent role in eradication of H pylori infection, and all treatments should be given for 14 days.

Abstract
Bismuth triple therapy was the first effective Helicobacter pylori eradication therapy. The addition of a proton pump inhibitor helped overcome metronidazole resistance. Its primary indication is penicillin allergy or when clarithromycin and metronidazole resistance are both common. Resistance to the primary first-line therapy have centered on complexity and difficulties with compliance. Understanding regional differences in effectiveness remains unexplained because of the lack of studies including susceptibility testing and adherence data. We discuss regimen variations including substitutions of doxycycline, amoxicillin, and twice a day therapy and provide suggestions regarding what is needed to rationally and effectively use bismuth quadruple therapy.

Abstract
The efficacy of seven-day clarithromycin-based standard triple therapy (STT) for Helicobacter pylori has decreased in Korea over the past decade. The aim of this meta-analysis was to clarify the efficacy of first-line and second-line therapies in Korea. This systematic review will provide an overview of H. pylori eradication and present new therapeutic strategies used in Korea. An extensive search of the literature concerning STT, sequential therapy (SET), concomitant therapy (CT), bismuth-containing quadruple therapy (BCQT) and various other therapies used in Korea was performed. All selected studies were randomized controlled trials (RCTs). Eighteen RCTs were eligible for systematic review. The alternative regimens comparing seven-day STT as a first-line therapy include SET, CT, levofloxacin-based therapy (LBT), BCQT, and STT with prolonged duration. The results of the meta-analysis suggest that SET is superior to seven-day STT. The overall eradication rate by intention to treat (ITT) analysis was 69.8% for STT and 79.7% for SET. The overall eradication rate by per-protocol (PP) analysis was 77.0% for STT and 85.0% for SET. The odds ratios for the ITT and PP eradication rate were 0.57 (95% confidence interval [CI], 0.43 to 0.74) and 0.52 (95% CI, 0.35 to 0.76), respectively. In the subgroup analysis, however, there were no significant differences between SET and STT with prolonged durations. Alternative regimens to seven-day BCQT as second-line therapy include LBT, moxifloxacin-based therapy and 14-day BCQT. The eradication rates of these alternative regimens were not superior to that of the conventional treatment. SET is superior to seven-day STT but not to STT with prolonged duration.

Appropriate first-line regimens to combat Helicobacter pylori antibiotic resistance: an Asian perspective. Molecules 2015; 20:6068-92. [PMID: 25856059 PMCID: PMC6272313 DOI: 10.3390/molecules20046068] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Revised: 03/20/2015] [Accepted: 04/02/2015] [Indexed: 01/06/2023] Open
Abstract
Asia has the largest population of any continent and the highest incidence of gastric cancer in the world, making it very important in the context of Helicobacter pylori infection. According to current guidelines, standard triple therapy containing a proton pump inhibitor (PPI) and two antibiotics; amoxicillin (AMX) and clarithromycin (CAM) or metronidazole (MNZ), is still the preferred first-line regimen for treatment of H. pylori infection. However, the efficacy of legacy triple regimens has been seriously challenged, and they are gradually becoming ineffective. Moreover, some regions in Asia show patterns of emerging antimicrobial resistance. More effective regimens including the bismuth and non-bismuth quadruple, sequential, and dual-concomitant (hybrid) regimens are now replacing standard triple therapies as empirical first-line treatments on the basis of the understanding of the local prevalence of H. pylori antimicrobial resistance. Selection of PPI metabolized by the non-enzymatic pathway or minimal first pass metabolism and/or increasing dose of PPI are important to increase H. pylori eradication rates. Therefore, local antibiotic resistance surveillance updates, selection of appropriate first-line regimens with non-enzymatic PPI and/or increased doses of PPI, and detailed evaluation of patients' prior antibiotic usage are all essential information to combat H. pylori antibiotic resistance in Asia.

Abstract
Treatment of Helicobacter pylori (H. pylori) infection is paramount for the management of prevalent gastrointestinal disorders including peptic ulcer disease and gastric cancer. Due to the wide increase in prevalence of H. pylori resistance to antibiotics, clarithromycin-based triple therapies are not any more suitable for unconditional empiric use, and should not be recommended, unless local resistance to this antibiotic is low (< 20%). Alternative strategies have been proposed to overcome the issue of increasing clarithromycin resistance, and some of them are already implemented in clinical practice. These comprise: (1) adoption of novel, more effective, empirical treatments: bismuth quadruple, sequential, non-bismuth quadruple (concomitant), dual-concomitant (hybrid), and levofloxacin-based regimens, the latter mainly designated as second-line/rescue options; (2) perspectives for a susceptibility-guided (tailored) therapeutic approach based on culture-free molecular testing methods; and (3) adjunct use of probiotics to improve eradication rates. The present article is aimed to provide a comprehensive overview of current and emerging strategies in the treatment of H. pylori infection, focusing on the challenge of antimicrobial resistance.

Abstract
INTRODUCTION Treatment of Helicobacter pylori (H. pylori) infection is crucial for prevalent disease's management, including gastritis, peptic ulcer and gastric cancer, whereas novel extradigestive causal associations are increasingly being recognized. Despite long-standing efforts, there is not as yet an optimal empirical therapy to eradicate H. pylori. AREAS COVERED In the present article the authors review current options for H. pylori eradication. Advantages and disadvantages of each of the recommended regimens, and the perspectives for their rational use in clinical practice, are critically discussed. EXPERT OPINION The continuous rising of antimicrobial resistance has accounted for the declined efficiency of standard triple therapies, yielding < 70% eradication in most countries. Alternative first-line strategies have been proposed and largely validated and are now replacing standard-of-care therapies in areas with a high incidence of clarithromycin-resistance (> 20%). Such treatments include the bismuth-containing quadruple therapy, concomitant, sequential and levofloxacin-based regimens, the later mainly designated, together with rifabutin-based therapies as second-line/rescue options. Clinicians should be aware of the local resistance pattern and maintain first-line eradication to levels > 90% (per-protocol efficacy). This will prevent both exposing the patient to repeated treatments and spreading of secondary antimicrobial resistance. In the future, perspectives of tailored therapy and a prophylactic vaccine will obviate any treatment concern.

Abstract
Background/Aims This study assessed the efficacy of a rifaximin plus levofloxacin-based rescue regimen in patients that had failed both triple and quadruple standard regimens for the eradication of Helicobacter pylori. Methods We treated patients for H. pylori between August 2009 and April 2011. The triple regimen consisted of combined treatment with amoxicillin, clarithromycin, and pantoprazole for 1 week. For failed cases, a quadruple regimen of tetracycline, metronidazole, bismuth dicitrate, and lansoprazole for 1 week was administered. The rescue regimen for persistently refractory cases was rifaximin 200 mg t.i.d., levofloxacin 500 mg q.d., and lansoprazole 15 mg b.i.d. for 1 week. Results In total, 482 patients were enrolled in this study. The eradication rates associated with the first and second regimens were 58% and 60%, respectively. Forty-seven out of 58 patients who failed with the second-line regimen received rifaximin plus levofloxacin-based third-line therapy. The eradication rate for the third regimen was 65%. The cumulative eradication rates were 58%, 85%, and 96% for each regimen, respectively. Conclusions A rifaximin plus levofloxacin-based regimen could be an alternative rescue therapy in patients with resistance to both triple and quadruple regimens for the eradication of H. pylori.

Abstract
Helicobacter pylori resistance rates to antibiotics vary in different countries and even in different regions of the same country. Choice of treatment is strongly dependent on antibiotic resistance rates. In some countries, triple therapy with a proton-pump inhibitor, amoxicillin, and clarithromycin is still the best option, but eradication results fall short of what would be desired (90-95%) in countries with clarithromycin resistance >20%, bismuth-containing quadruple therapy, or nonbismuth sequential or concomitant therapies may then be the preferred option. Newer antibiotic regimens are awaited. Vaccination would be the best option, especially for developing countries, but little progress has been made in designing a vaccine.
