Abstract
INTRODUCTION Antibiotic resistance is one of the main factors that determine the efficacy of treatments to eradicate Helicobacter pylori infection. Our aim was to evaluate the effectiveness of first-line and rescue treatments against H. pylori in Europe according to antibiotics resistance. METHODS Prospective, multicenter, international registry on the management of H. pylori (European Registry on H. pylori Management). All infected and culture-diagnosed adult patients registered in the Spanish Association of Gastroenterology-Research Electronic Data Capture from 2013 to 2021 were included. RESULTS A total of 2,852 naive patients with culture results were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 22%, 27%, and 18%, respectively. The most effective treatment, regardless of resistance, were the 3-in-1 single capsule with bismuth, metronidazole, and tetracycline (91%) and the quadruple with bismuth, offering optimal cure rates even in the presence of bacterial resistance to clarithromycin or metronidazole. The concomitant regimen with tinidazole achieved an eradication rate of 99% (90/91) vs 84% (90/107) with metronidazole. Triple schedules, sequential, or concomitant regimen with metronidazole did not achieve optimal results. A total of 1,118 non-naive patients were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 49%, 41%, and 24%, respectively. The 3-in-1 single capsule (87%) and the triple therapy with levofloxacin (85%) were the only ones that provided encouraging results. DISCUSSION In regions where the antibiotic resistance rate of H. pylori is high, eradication treatment with the 3-in-1 single capsule, the quadruple with bismuth, and concomitant with tinidazole are the best options in naive patients. In non-naive patients, the 3-in-1 single capsule and the triple therapy with levofloxacin provided encouraging results.

[PMID: 36801622 DOI: 10.1016/j.ejca.2023.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/20/2022] [Accepted: 01/10/2023] [Indexed: 01/26/2023]
Abstract
OBJECTIVES To provide an evidence-based, comprehensive assessment of the current burden of infection-related cancers in Italy. METHODS We calculated the proportion of cancers attributable to infectious agents (Helicobacter pylori [Hp]; hepatitis B virus [HBV] and hepatitis C virus [HCV]; human papillomavirus [HPV]; human herpesvirus-8 [HHV8]; Epstein-Barr virus [EBV]; and human immunodeficiency virus [HIV]) to estimate the burden of infection-related cancer incidence (2020) and mortality (2017). Data on the prevalence of infections were derived from cross-sectional surveys of the Italian population, and relative risks from meta-analyses and large-scale studies. Attributable fractions were calculated based on the counterfactual scenario of a lack of infection. RESULTS We estimated that 7.6% of total cancer deaths in 2017 were attributable to infections, with a higher proportion in men (8.1%) than in women (6.9%). The corresponding figures for incident cases were 6.5%, 6.9% and 6.1%. Hp was the first cause of infection-related cancer deaths (3.3% of the total), followed by HCV (1.8%), HIV (1.1%), HBV (0.9%), HPV, EBV and HHV8 (each ≤0.7%). Regarding incidence, 2.4% of the new cancer cases were due to Hp, 1.3% due to HCV, 1.2% due to HIV, 1.0% due to HPV, 0.6% due to HBV and <0.5% due to EBV and HHV8. CONCLUSIONS Our estimate of 7.6% of cancer deaths and 6.9% of incident cases that were attributable to infections in Italy is higher than those estimated in other developed countries. Hp is the major cause of infection-related cancer in Italy. Prevention, screening and treatment policies are needed to control these cancers, which are largely avoidable.

Abstract
Abstract
Background
The eradication rate of Helicobacter pylori (H. pylori) decreased gradually. This study aimed to analyze the efficacy and safety of a 14-day combination of vonoprazan and amoxicillin as the first-line eradication therapy for H. pylori infection, and compared them with those of the bismuth quadruple therapy.
Methods
A prospective randomized clinical trial (RCT) was designed, involving patients with H. pylori infection in 6 institutions who did not receive any treatment yet. They were randomly assigned into VA-dual group (vonprazan 20mg b.i.d + amoxicillin 750mg q.i.d) or EACP-quadruple group (esomeprazole 20mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth subcitrate 220mg b.i.d) for 14 days in ratio of 1:1. At least 28 days later, the eradication rate were detected by the 13C-urea breath test (UBT).
Results
A total of 562 patients from February 2022 to September 2022 were enrolled and 316 were randomly. In the ITT analysis, the eradication rates of H. pylori in VA-dual group and EACP-quadruple group were 89.9% and 81.0% respectively, p = 0.037. In the PP analysis were 97.9% and 90.8%, p = 0.009. The different eradication rate was 8.9% (95%CI, 1.2–16.5%) and 7.2% (95%CI, 1.8–12.4%) in ITT and PP analysis, both lower limit of the 95%CI was still higher than the prespecified margin. In addition, the incidence of adverse events in VA-dual group was significantly lower than that in EACP-quadruple group (19.0% vs. 43.0%, P < 0.001).
Conclusion
The efficacy and safety of a 14-day combination therapy of vonoprazan and amoxicillin in eradicating H. pylori are superior to bismuth quadruple therapy, and this combination significantly reduces the use of antibiotics.

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

Abstract
Helicobacter pylori infection is very common and affects more than one-third of adults in Italy. Helicobacter pylori causes several gastro-duodenal diseases, such as gastritis, peptic ulcer and gastric malignancy, and extra-gastric diseases. The eradication of the bacteria is becoming complex to achieve due to increasing antimicrobial resistance. To address clinical questions related to the diagnosis and treatment of Helicobacter pylori infection, three working groups examined the following topics: (1) non-invasive and invasive diagnostic tests, (2) first-line treatment, and (3) rescue therapies for Helicobacter pylori infection. Recommendations are based on the best available evidence to help physicians manage Helicobacter pylori infection in Italy, and have been endorsed by the Italian Society of Gastroenterology and the Italian Society of Digestive Endoscopy.

Abstract
Background: Curing H. pylori infection remains challenging, and the use of most effective first-line therapy represents a therapeutic cornerstone. To monitor the efficacy of first-line therapies in Italy, we designed a systematic review with pooled- data analysis of data published in the last 15 years.
Methods: The search was focused on standard regimens and adult patients. Studies that included modified therapy regimens, pediatric patients, case series with less than 5 patients, and those in language other than English were excluded.
Results: A total of 40 studies, with 74 therapeutic arms and 13,539 patients were evaluated. Among the 14-day triple therapies, the combination with proton pump inhibitor (PPI), clarithromycin and amoxicillin achieved the highest (77.9%) success rate, whilst the lowest success rate (62.7%) was observed following the 14-day PPI, clarithromycin and tinidazole regimen. The overall efficacy of triple therapies significantly decreased from 75.7% to 72.1% in the last decade. Sequential (88.3% on 3431 patients), concomitant (88.8% on 376 patients), and the bismuth-based quadruple therapy with three-in-one capsule, containing bismuth subcitrate potassium (140 mg), metronidazole (125 mg), tetracycline (125 mg) (90.4% on 999 patients) achieved similarly high eradication rates, but data on concomitant are still limited. The bismuth-based was associated with the higher (38.7%) incidence of side-effects.
Conclusions: Data found that all triple therapies, irrespective of drug combination and therapy duration, should be abandoned in Italy due to their unacceptable low success rates. Monitoring the efficacy of standard first-line therapies in other countries could be clinically useful for both patients and clinicians.

Abstract
BACKGROUND Information on the management of Helicobacter (H.) pylori infection by gastroenterologists and gastroenterology fellows are scarce. We aimed to assess practice of gastroenterologists and gastroenterology fellows and their adherence to guidelines for diagnosis and treatment of H. pylori infection in Italy. MATERIALS AND METHODS All gastroenterologists and gastroenterology fellows attending the National Congress of Digestive Diseases - FISMAD were invited to fill-in an on-line questionnaire. The questionnaire included questions on the diagnosis and treatment of H. pylori infection. RESULTS A total of 279 gastroenterologists and 61 gastroenterology fellows participated to the study. The 13 C-urea breath test was the most preferred method among gastroenterologists and fellows for the diagnosis of H. pylori infection (40.4% and 57.6%, respectively) and the confirmation of eradication (61.3% and 70%, respectively). Sequential therapy was the most preferred first-line treatment of H. pylori for both gastroenterologists and gastroenterology fellows (31.8% and 44%, respectively), followed by bismuth quadruple therapy (31% and 27.6%, respectively) and clarithromycin triple therapy (26.8% and 22.4%, respectively). Only 30% of gastroenterologists and 38.5% of fellows used the clarithromycin triple therapy for the recommended duration of 14 days. Bismuth quadruple therapy was the most preferred second-line therapy for both gastroenterologists and fellows. The majority of gastroenterologists and fellows would prefer an empirical therapy at third line (72.6% and 62.5%, respectively) and a susceptibility-guided therapy at fourth line (46.7% and 71.4%, respectively). CONCLUSIONS Practices of gastroenterologists and gastroenterology fellows are in line with guidelines' recommendations, apart for the first-line treatment of H. pylori infection. Targeted educational interventions to improve adherence to guidelines are needed.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy and safety of bismuth pectin capsules and bismuth pectin granules in the first-line quadruple treatment of Helicobacter pylori (H. pylori). METHODS This study was a multicenter, randomized, open-labelled controlled clinical trial. Patients with a H. pylori infection were randomized into 4 groups (1:1:1:1) and treated with a 14-day bismuth-containing quadruple therapy. The 4 groups received either bismuth potassium citrate capsules (220 mg), colloidal bismuth pectin capsules (200 mg), bismuth pectin granules (150 mg), or bismuth pectin granules (300 mg). The primary outcome was the eradication rate of H. pylori. The secondary outcomes included symptom improvement, patient compliance, and incidence of adverse events. This study was registered at ClinicalTrials.gov (NCT04209933). RESULTS A total of 240 patients were included in this study, and 211 patients completed the follow-up. An intention-to-treat analysis showed that the H. pylori eradication rates of the 4 groups were 73.3%, 76.7%, 75.0%, and 71.7%, respectively. The per-protocol analysis showed that the H. pylori eradication rates of the 4 groups were 86.3%, 82.1%, 83.3%, and 86.0%. There was no significant difference among the 4 groups in the H. pylori eradication rate (P > .05). There were also no significant differences in the symptom improvement rate, overall adverse reaction rate, or patient compliance among the 4 groups. CONCLUSIONS Bismuth pectin capsules and bismuth pectin granules had similar efficacy and safety for H. pylori eradication compared to bismuth potassium citrate. These data suggest that bismuth pectin can be an alternative to bismuth potassium citrate to eradicate H. pylori when using bismuth-containing quadruple therapy.

Abstract
The prevalence of Helicobacter pylori infection remains significant worldwide and it depends on many factors: gender, age, socio-economic status, geographic area, diet, and lifestyle. All successful infectious diseases treatments use antibiotic-susceptibility testing, but this strategy is not currently practical for H. pylori and the usual cure rates of H. pylori are lower than other bacterial infections. Actually, there is no treatment that ensures complete eradication of this pathogen. In the context of an alarming increase in resistance to antibiotics (especially to clarithromycin and metronidazole), alternative and complementary options and strategies are taken into consideration. As the success of antibacterial therapy depends not only on the susceptibility to given drugs, but also on the specific doses, formulations, use of adjuvants, treatment duration, and reinfection rates, this review discusses the current therapies for H. pylori treatment along with their advantages and limitations. As an alternative option, this work offers an extensively referenced approach on natural medicines against H. pylori, including the significance of nanotechnology in developing new strategies for treatment of H. pylori infection.

Abstract
Helicobacter pylori (H. pylori) infection is associated with the development of multiple diseases. The eradication rate of H. pylori has gradually decreased, suggesting the need to discover more effective therapies. This study aimed to compare the effectiveness of first-line treatments including high-dose dual therapy (HDDT), bismuth-based quadruple therapy (BQT), sequential therapy (ST), concomitant therapy (CT) and hybrid therapy (HT) by network meta-analysis (NMA). A comprehensive search on PubMed, Embase, Cochrane Library and Web of Science, was performed from their inception to 1 September 2019. A network analysis of randomized controlled trials (RCTs) comparing first-line therapies were carried out using Stata 14.0 and Revman 5.2. Moreover, a sensitivity analysis was conducted by omitting non-Asian studies. Finally, 41 RCTs with 14 119 patients were included. The NMA showed that, in terms of eradication rate, ST for 10 days (ST-10) was significantly lower than CT for 10 or 14 days (CT ≥ 10). Sensitivity analysis among the Asian population showed that ST-10 denoted the lowest effectiveness among the interventions. The ranking results based on probability showed that HDDT ranked first for the eradication rate. As for adverse events, HDDT was significantly less than BQT and CT regardless of duration, while BQT for 14 days represented higher adverse events than ST, HT and CT ≥ 10. HDDT ranked first among the therapies. In conclusion, HDDT for 14 days appeared to be the most optimal first-line therapy for H. pylori among the Asian population with comparable efficacy and compliance but causing fewer adverse events.

Abstract
Background and aim: Bismuth quadruple therapy (BQT) or non-bismuth quadruple therapy (i.e., concomitant therapy) (CT) is the first-line regimens to eradicate H. pylori infection in areas with high prevalence of clarithromycin (CLA) resistance. Guidelines suggest that in areas of high prevalence of H. pylori strains with double resistance (i.e., CLA + metronidazole), BQT should be preferred to CT. The aim of this study was to evaluate the efficacy and safety of BQT administered through the three-in-one pill (Pylera) formulation in a large series of H. pylori–infected patients, naive to treatment in a region with high CLA and dual resistance. Patients and methods: We treated 250 patients (148 F and 102 M, mean age 48.6 years) with H. pylori infection naïve to treatment. Patients received esomeprazole 40 mg bid and Pylera 3 tablets qid for 10 days. Diagnosis of H. pylori infection was through 13C urea breath test (13C UBT), or stool antigen test or histology, as appropriate. The evaluation of eradication was through 13C UBT at least 45 days after the end of therapy. Incidence of treatment-related adverse events (TRAEs) was assessed through a questionnaire at the end of treatment. Compliance was considered good if at least 90% of medication had been taken. Statistical analysis was per intention-to-treat e per protocol (PP). 95% confidence intervals (CIs) were calculated. Results: 1) 13 patients (5.2%) discontinued therapy due to side effects; 2) eradication rates in ITT and PP were 227/250 (90.8%; 95% CI 86.3–93.7%) and 226/237 (95.3%; 95% CI 91–99%), respectively; 3) the prevalence of TRAEs was 26.8%; and 4) adherence to treatment was good with compliance greater than 90%. Conclusion: In this real-life study, we demonstrate that in an area with a high prevalence of H. pylori strains with CLA or CLA + metronidazole resistance, BQT using Pylera is an effective therapeutic strategy with ITT eradication rates higher than 90%; this therapy is associated with good compliance and low incidence of side effects.

Abstract
Helicobacter pylori strains carry a range of mutations in genes that confer antimicrobial resistance and restrict the available options to treat the infection. Latin America is a region that conserve a large number of indigenous communities relatively isolated that practice a traditional medicine without consumption of drugs. We hypothesized that rates of antibiotic resistance are lower in these communities. Recent progress in whole-genome sequencing has allowed the study of drug susceptibility by searching for the known mutations associated with antibiotic resistance. The aim of this work was to study trends of antibiotic resistance over a 20-year period in Mexican H. pylori strains and to compare susceptibility between strains from Mexican mestizos and from indigenous population; we also aimed to learn the prevalence of mutational patterns in genes gyrA, gyrB, rdxA, frxA, rpsU, omp11, dppA, and 23S rRNA and its association with phenotypic tests. Resistance to clarithromycin, metronidazole, amoxicillin and levofloxacin was determined in167 H. pylori isolates by E-test, and the occurrence of mutational patterns in specific genes was determined by whole genome sequencing (WGS). The trend of resistance over 20 years in mestizo isolates showed significant resistant increase for clarithromycin and levofloxacin to frequencies that banned its clinical use. Resistance in H. pylori isolates of native communities was lower for all antibiotics tested. Phenotypic resistance showed good to moderate correlation with genotypic tests. Genetic methods for characterizing antibiotic resistance require further validation in each population.

Abstract
BACKGROUND Quadruple therapy using a single capsule formulation of bismuth, metronidazole and tetracycline (BMT; Pylera®), associated with omeprazole for the eradication of Helicobacter pylori, represents the reintroduction of bismuth in France after 40 years. OBJECTIVE To describe the real-life patterns of use of BMT following a request from the French health authorities. METHODS Patients with a first BMT dispensing (index date, ID), with one year of data before and after ID, were identified in the French nationwide claims database 1/97 sample. Misuse of BMT was defined as dispensing>1 pack of BMT at ID or absence of a diagnostic test in the preceding year. RESULTS In total, 540 patients were included. Prescribers were gastroenterologists (n=243; 45%) and general practitioners (n=160; 30%). A proton pump inhibitor was co-dispensed to 504 patients (96%). Ten patients (2%) had contraindications to BMT. Fifty-nine patients (11%) met the misuse criteria: ten (2%) were dispensed>1 pack of BMT and 49 (9%) had not had a diagnostic test for H. pylori in the previous year. During follow-up, 27 patients (5%) required retreatment (treatment failure). CONCLUSION In this real-life study, most patients were dispensed only one pack of BMT, consistent with recommendations. Misuse related principally to the absence of prior diagnostic test for H. pylori.

Abstract
Introduction: Eradication of Helicobacter pylori (H. pylori) becomes more challenging due to increasing antimicrobial resistance. Consequently, the performance of clarithromycin-containing triple therapies is now declining to unacceptable levels and should be abandoned unless a prior susceptibility test precludes clarithromycin resistance.Areas covered: This review summarizes updated evidence concerning new and advancing pharmacotherapy options for H. pylori eradication.Expert opinion: Due to the declining efficacy of legacy triple therapies, most guidelines recommend bismuth quadruple therapy as the best initial empiric treatment. Concomitant, sequential and hybrid therapies are remarkable bismuth-free quadruple options, provided that dual clarithromycin-metronidazole resistance is low. Levofloxacin-, rifabutin-, furazolidone- and sitafloxacin-containing regimens remain useful, particularly as salvage options. To eradicate H. pylori in line with the rules of antibiotic stewardship, susceptibility-guided treatment appears as the ideal approach. However, the feasibility and cost-effectiveness of universal pre-treatment susceptibility testing warrants further evaluation. Molecular testing methods promise convenient characterization of H. pylori antibiotic susceptibility. High-dose dual therapy (proton-pump-inhibitor plus amoxicillin) and vonoprazan, a more potent acid inhibitor that likely enhances the activity of amoxicillin, are promising alternatives that could decrease misuse of antibiotics. Addition of certain probiotics could somewhat increase the performance of H. pylori eradication regimens, while improving tolerability.

Abstract
Due to an imbalance between aggressive factors known as hydrochloric acid (HCl), pepsin, leukotrienes, refluxed bile, defensive factors and reactive oxygen species, the peptic ulcer is formed in the stomach and duodenum which mostly include the function of prostaglandins, mucus bicarbonate barrier, enzymatic antioxidants, and some growth factors. H. pylori infection remained one of the considerable causes of peptic ulcer as it caused hypochlorhydria and struck off the defense mechanism of the stomach. The nonsteroidal anti-inflammatory drugs (NSAIDs) and stress are the most prevailing causes of peptic ulcer disease. Lack of physical exercise, little rest and due to poor leisure cause the peptic ulcer disease. Candies, chocolate, coffee, cigarettes, stress, and alcohol are the cause of peptic ulceration and suppression of acid in the stomach due to the utilization of antacid medication. Most of the ancient medical practices in the traditional alternative medicinal system include Unani, Ayurveda, Siddha, Homeopathy, Naturopathy, Chinese customary medicine, African conventional medicine, and Native American medicine. Without a hostile effect, the rate of curing the disease is the significance of natural products research. Peptic ulcer disease is the widespread nature of peptic ulcer in all class of population, which mostly may be due to rapidly changing the food habits and stress, causing the imbalance between gastric offensive and defensive factors. Curcuma longa is the most effective plant for the cure of peptic ulcer. Curcuma longa has anti-inflammatory and antioxidant activity. Curcuma longa remarkably reduces the level of inflammatory mediator (IL1) and (TNF) which was increased during the formation of an ulcer. In the rhizome of Curcuma longa, yellow pigment is present and widely used for the treatment of ulcer and decrease the inflammatory response. Symptoms include abdominal pain after taking a meal, nausea, vomiting, Anorexia and lose weight.

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
Antibiotic resistance is the major reason for Helicobacter pylori treatment failure, and the increasing frequency of antibiotic resistance is a challenge for clinicians. Resistance to clarithromycin and metronidazole is a particular problem. The standard triple therapy (proton pump inhibitor, amoxicillin, and clarithromycin) is no longer appropriate as the first-line treatment in most areas. Recent guidelines for the treatment of H. pylori infection recommend a quadruple regimen (bismuth or non-bismuth) as the first-line therapy. This treatment strategy is effective for areas with high resistance to clarithromycin or metronidazole, but the resistance rate inevitably increases as a result of prolonged therapy with multiple antibiotics. Novel potassium-competitive acid blocker-based therapy may be effective, but the data are limited. Tailored therapy based on antimicrobial susceptibility test results is ideal. This review discussed the current important regimens for H. pylori treatment and the optimum H. pylori eradication strategy.

Abstract
INTRODUCTION AND OBJECTIVES quadruple therapy with bismuth is recommended as a first line treatment for Helicobacter pylori (H. pylori) infection. The aim of this study was to evaluate the compliance, adverse effects and effectiveness of this treatment with the new galenic three-in-one capsule formulation containing bismuth subcitrate, metronidazole and tetracycline (Pylera®). METHODS a prospective, non-controlled, single center observational study was performed in a cohort of 200 consecutive patients with an untreated H. pylori infection; 58% were female. The subjects were treated for ten days with Pylera® of three capsules four times daily with meals and a proton pump inhibitor taken before breakfast and dinner. The Pylera® capsule contains 140 mg of bismuth subcitrate, 125 mg of metronidazole and 125 mg of tetracycline. The compliance and adverse effects of the treatment were evaluated via telephone contact and via an interview during the clinical revision. Eradication of infection was controlled for at least four weeks after treatment termination via the urea breath test, the stool antigen test with monoclonal antibodies or by histology. RESULTS treatment compliance was observed in 96% (192/200) of the patients. Only 28.5% (57/200) of the patients experienced adverse effects, which led to abandoning the treatment in only seven subjects. Severe adverse effects developed in only one case due to Clostridium difficile infection. The effectiveness based on intention to treat was 91.5% (183/200, 95% CI: 87.1-96.8) and per protocol was 95.2% (182/191, 95% CI: 90.9-98.9). CONCLUSIONS in our experience, Pylera® is an effective and safe treatment that should be considered as a first line therapeutic option for the eradication of H. pylori infection.

Seven-day vonoprazan and low-dose amoxicillin dual therapy as first-line Helicobacter pylori treatment: a multicentre randomised trial in Japan. Gut 2020; 69:1019-1026. [PMID: 31915235 PMCID: PMC7282559 DOI: 10.1136/gutjnl-2019-319954] [Citation(s) in RCA: 140] [Impact Index Per Article: 35.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 12/04/2019] [Accepted: 12/25/2019] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To date, no randomised trials have compared the efficacy of vonoprazan and amoxicillin dual therapy with other standard regimens for Helicobacter pylori treatment. This study aimed to investigate the efficacy of the 7-day vonoprazan and low-dose amoxicillin dual therapy as a first-line H. pylori treatment, and compared this with vonoprazan-based triple therapy. DESIGN This prospective, randomised clinical trial was performed at seven Japanese institutions. Patients with H. pylori-positive culture test and naive to treatment were randomly assigned in a 1:1 ratio to either VA-dual therapy (vonoprazan 20 mg+amoxicillin 750 mg twice/day) or VAC-triple therapy (vonoprazan 20 mg+amoxicillin 750 mg+clarithromycin 200 mg twice/day) for 7 days, with stratification by age, sex, H. pylori antimicrobial resistance and institution. Eradication success was evaluated by 13C-urea breath test at least 4 weeks after treatment. RESULTS Between October 2018 and June 2019, 629 subjects were screened and 335 were randomised. The eradication rates of VA-dual and VAC-triple therapies were 84.5% and 89.2% (p=0.203) by intention-to-treat analysis, respectively, and 87.1% and 90.2% (p=0.372) by per-protocol analysis, respectively. VA-dual was non-inferior to VAC-triple in the per-protocol analysis. The eradication rates in strains resistant to clarithromycin for VA-dual were significantly higher than those for VAC-triple (92.3% vs 76.2%; p=0.048). The incidence of adverse events was equal between groups. CONCLUSION The 7-day vonoprazan and low-dose amoxicillin dual therapy provided acceptable H. pylori eradication rates and a similar effect to vonoprazan-based triple therapy in regions with high clarithromycin resistance. TRIAL REGISTRATION NUMBER UMIN000034140.

Abstract
INTRODUCTION A fixed-dose association of bismuth subcitrate, metronidazole and tetracycline (BMT) (Pylera®, Allergan, NJ, USA) was made available in France in 2013 for the eradication of Helicobacter pylori. Due to a historical issue of bismuth encephalopathy, the French Health Authorities requested a study of blood and plasma bismuth concentrations with BMT in daily practice. AIMS The aim of the study was to measure eventual bismuth accumulation and neurological toxicity in patients prescribed BMT. METHODS Patients initiating BMT for H. pylori between March 2014 and December 2015 were included. A blood sample was taken before first BMT intake and 24 h after the last intake, for assay of bismuth. A concentration > 50 μg/L was considered abnormal. Neurological complaints were assessed at inclusion, at the end of the 10-day treatment course, and 28 days later. RESULTS 202 patients were included, of whom 190 took at least one dose of BMT, and 167 provided both required blood samples. Mean blood bismuth concentrations after the BMT course were 16.9 μg/L (95% confidence interval 15.6-18.3). Concentrations were > 50 μg/L (56.0 μg/L and 50.9 μg/L) in two elderly patients, one of whom presented mild, transient memory impairment during treatment. Non-serious neurological symptoms occurred in 20% of all patients and treatment failure was documented in 5% of patients. CONCLUSIONS In this study measuring blood bismuth concentrations in real-life practice, in < 1% of patients the BMT course resulted in blood bismuth concentrations > 50 μg/L. No serious neurological adverse events were observed. STUDY REGISTRATION EU-PAS register EUPAS3142 at www.encepp.eu ; ENCePP study seal.

Abstract
Objective: Helicobacter pylori antibiotic resistance is a constantly evolving process and local surveillance is warranted to guide clinicians in the choice of therapy. Materials and Methods: Antibiotic susceptibility testing was performed by E-test on 92 H. pylori strains, and resistance to clarithromycin and levofloxacin was also evaluated using a commercially available genotyping method. Results: In naïve patients the resistance to clarithromycin, levofloxacin, and metronidazole was 37.7%, 26.2%, and 16.4%, respectively, significantly lower than the percentage found in treated patients. Concomitant resistance to ≥2 antibiotics was also observed in naïve patients. The A2143G mutation of the 23S-rRNA gene was the most frequently detected, also in naïve patients. The highest minimum inhibitory concentration (MIC)50 value (256 mg/L) was associated with A2142 mutations in all the patients carrying them. For levofloxacin resistance a mutation in codon 87 was detected in 63.9% and in codon 91 in 36.1% of the H. pylori strains, without significant differences in the patients groups. A mutation in codon 87 was associated with the highest MIC50 value (32 mg/L). Conclusions: In our area, a high prevalence of H. pylori primary resistance was detected; these rates were higher in patients who had experienced failure of several courses of therapy. A better knowledge of the local epidemiology of resistance, and the genotypes responsible, will improve the H. pylori eradication rates.

Abstract
BACKGROUND AND AIMS the increasing prevalence of strains resistant to antimicrobial agents is a critical issue for the management of Helicobacter pylori infection. This study aimed to evaluate, in Italian naïve patients, H. pylori antibiotic resistance trends and their potential predictive factors during the last decade. METHODS consecutive Italian naïve H. pylori positive patients, referred from General Practitioners to our Unit from January 2009 to January 2019 to perform an upper gastrointestinal endoscopy (UGIE), were considered. Each patient underwent 13C-urea breath test (13C-UBT) and UGIE with multiple biopsies to perform rapid urease test (RUT), culture/susceptibility test (vs. clarithromycin, metronidazole, levofloxacin), and histopathological examination. H. pylori status was assessed through CRM (composite reference method: at least two tests positive or only culture positive). RESULTS between 2009 and 2014, 1763 patients were diagnosed as H. pylori positive, 907 were naïve with antibiogram available. Between 2015 and 2019, 1415 patients were diagnosed as H. pylori positive, antibiotic susceptibility test was available in 739 naïve patients. H. pylori primary antibiotic resistance rates in the first and second five-year period were, respectively, clarithromycin 30.2% (95% CI 27.2-33.3), 37.8% (95% CI 34.2-41.4); metronidazole 33.3% (95% CI 30.2-36.5), 33.6% (95% CI 30.2-37.1); levofloxacin 25.6% (95% CI 22.8-28.5), 33.8% (95% CI 37.4-47.4), double resistance clarithromycin-metronidazole 18.9% (95% CI 16.4-21.6), 20.7% (95% CI 17.8-23.8). The increase of the resistance rates to clarithromycin and levofloxacin in naïve patients was statistically significant (p < 0.05). Although eradication rates for sequential therapy in the 10 years considered were 93.4% (95% CI 92-94.6) and 87.5% (95% CI 85.7-89) at per-protocol (PP) and intention-to-treat (ITT) analysis, respectively, they showed a significant decrease in the second five-year period. CONCLUSIONS this data highlights an increase in primary H. pylori antibiotic resistance and strongly suggests the importance of drug susceptibility testing also in naïve patients.

Abstract
This review summarizes important studies regarding Helicobacter pylori therapy published from May 2018 to May 2019. The main themes that emerge involve studies assessing the efficacy of bismuth-based regimens. While in recent years the efficacy of bismuth-based quadruple therapy as a second-line therapy has been clearly established, there is now substantial evidence that it is the best performing first-line therapy. Antibiotic resistance was again intensely studied this year, and a clear and dramatic increase in resistance is noted for clarithromycin and levofloxacin; most notably, it may not be possible to support these therapies in most regions of the world much longer without testing. The utility of vonoprazan as an alternative to proton-pump inhibitor therapy, especially in resistant and difficult to treat groups, has also been considered in greater detail this year, as well as means of supporting and enhancing adherence to therapy. Several studies showed that the diversity of gut microbiota was significantly altered shortly after H pylori eradication. However, the diversity was restored to pre-treatment state after 2 months in patients treated with triple therapy. More studies are warranted to assess the long-term changes of gut microbiota after H pylori eradication.

Abstract
BACKGROUND Bismuth-containing quadruple therapy has been suggested as first-line and rescue alternative for Helicobacter pylori eradication. Our objective was to perform a meta-analysis evaluating the efficacy and safety of single capsule Pylera® (bismuth, metronidazole, and tetracycline) plus a proton-pump inhibitor (PPI) in any line of treatment. METHODS Studies were selected up to October 2018. Outcomes were eradication and adverse events (AEs) rates pooled using the generic inverse variance method. RESULTS In total, 30 studies (6482 patients) were included in the systematic review. The intention-to-treat (ITT) efficacy was 90% (95% CI: 87%-92%, 21 studies, I2 = 88%) in first-line therapy, 89% (95% CI: 86%-93%, 12 studies, I2 = 78%) in second-line and 82% (95% CI: 78%-87%, nine studies, I2 = 60%) in third-line; with no differences by the type or dosage of PPI used. For metronidazole-resistant infection, the ITT efficacy as first-line therapy was 93% (95% CI: 90%-96%, six studies, I2 = 0%). In second-line therapies where patients had been previously treated with clarithromycin, the ITT efficacy was 90% (95% CI: 87%-93%, 11 studies, I2 = 78%). The overall incidence of AEs was 43% (95% CI: 35%-50%, 24 studies, I2 = 92%) and they were mostly mild. In nearly 3% of the cases, treatment was interrupted due to AEs. CONCLUSIONS A 10-day treatment with Pylera® achieved an effective eradication rate of approximately 90% both in first- and second-line therapy. This applies regardless of the type and dose of the PPI, in patients with clarithromycin- or metronidazole-resistant strains, and in those previously treated with clarithromycin.

Abstract
BACKGROUND Concomitant quadruple (CQT) or bismuth-containing quadruple therapy (BQT) is recommended as first-line treatment for Helicobacter pylori infection depending on antibiotic resistance. AIM To compare the efficacy, safety, and compliance of CQT and BQT as first-line therapy for H. pylori eradication in real clinical practice in an area of high resistance to clarithromycin. METHODS A prospective, open, comparative cross-sectional study including dyspeptic patients >18 years with H. pylori infection and with no previous eradication treatment was performed. CQT (omeprazole 20 mg + clarithromycin 500 mg + amoxicillin 1 g + metronidazole 500 mg, all given twice daily, for 14 days) or BQT (omeprazole 20 mg twice daily + 3 capsules of Pylera® 4 times a day, for 10 days) was prescribed at the discretion of the prescribing physician. Eradication was tested by 13 C-urea breath test. Efficacy was assessed by intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS One hundred and four consecutive patients were included (64.4% female, age 52.9 years). Fifty patients received CQT and 54 BQT. Eradication rate was similar with both therapies at the PP (CQT 97.9%, 95% CI: 93.9-100 vs BQT 96.2%, 95% CI: 90.9-100, P = 0.605) and ITT analyses (CQT 98.0%, 95% CI: 94-100 vs BQT 94.4%, 95% CI: 88.1-100, P = 0.346). The rate of adverse events was also similar with CQT (56%) and BQT (46.3%). One patient in each group discontinued the treatment due to significant adverse events. CONCLUSION The use of CQT and BQT as first-line treatment against H. pylori is similarly effective and safe strategy in an area of high clarithromycin resistance.

Abstract
PURPOSE OF REVIEW Helicobacter pylori eradication rates have fallen in recent years, mainly because of the emergence of antibiotic-resistant infections. Indeed the WHO has recently designated clarithromycin-resistant H. pylori infection a high priority for antibiotic resistance research and development. This review aims to discuss the most up-to-date information on the methods to detect H. pylori antibiotic resistance, the recent data on resistance rates, and the most appropriate treatment strategies to overcome antibiotic resistance. RECENT FINDINGS There has been active research into the development and assessment of genotypic diagnostic assays for both the invasive and noninvasive detection of antibiotic-resistant infection. There are regional variations in the prevalence of H. pylori antibiotic resistance. Primary resistance rates in general are on the rise and high rates of clarithromycin resistance (>15%) have been reported in many parts of the world. SUMMARY Optimizing antimicrobial susceptibility testing by both invasive and noninvasive means is crucial to accurately evaluate resistance rates for the optimization of both regional and personalized H. pylori treatment strategies.

Abstract
Treatment options for the eradication of Helicobacter pylori continue to evolve. There have been many guidelines for H. pylori treatment published, which may lead to some confusion. However, most are in agreement with the most recent iteration of the Maastricht treatment guidelines. Triple therapy is still the most frequently used treatment, especially in areas of low clarithromycin resistance. Its best results are achieved when taken for a minimum of 10 days and with high-dose acid suppression. Quadruple therapy is gaining in popularity particularly in areas with increasing resistance to standard triple therapy. Whether three antibiotics, or bismuth and two antibiotics are used, excellent eradication rates are achieved, albeit with increased side effects. Levofloxacin second-line therapy is widely used; however bismuth, when available, is an increasingly successful option. Sequential therapy is challenging in terms of compliance and is no longer recommended. This past year witnessed a notable increase in the number of studies based on antimicrobial susceptibility testing and tailored eradication therapy, reflecting the role of culture-guided treatment, which may well represent the future of H. pylori treatment and prevent the inappropriate use of antibiotics.

Abstract
Helicobacter pylori (Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection. There is no ideal treatment for Hp. Hp infection is not cured by a single antibiotic, and sometimes, a combined treatment with three or more antibiotics is ineffective. Atrophic gastritis (AG) is a chronic disease whose main features are atrophy and/or intestinal metaplasia of the gastric glands, which arise from long-standing Hp infection. AG is reportedly linked to an increased risk for gastric cancer, particularly when extensive intestinal metaplasia is present. Active or past Hp infection may be detected by conventional methods in about two-thirds of AG patients. By immunoblotting of sera against Hp whole-cell protein lysates, a previous exposure to Hp infection is detected in all AG patients. According to guidelines, AG patients with Hp positivity should receive eradication treatment. The goals of treatment are as follows: (1) Cure of infection, resolution of inflammation and normalization of gastric functions; (2) possible reversal of atrophic and metaplastic changes of the gastric mucosa; and (3) prevention of gastric cancer. An ideal antibiotic regimen for Hp should achieve eradication rates of approximately 90%, and complex multidrug regimens are required to reach this goal. Amongst the factors associated with treatment failure are high bacterial load, high gastric acidity, Hp strain, smoking, low compliance, overweight, and increasing antibiotic resistance. AG, when involving the corporal mucosa, is linked to reduced gastric acid secretion. At a non-acidic intra-gastric pH, the efficacy of the common treatment regimens combining proton pump inhibitors with one or more antibiotics may not be the same as that observed in patients with Hp gastritis in an acid-producing stomach. Although the efficacy of these therapeutic regimens has been thoroughly tested in subjects with Hp infection, there is a paucity of evidence in the subgroup of patients with AG. Bismuth-based therapy may be an attractive treatment in the specific setting of AG, and specific studies on the efficacy of bismuth-based therapies are needed in patients with AG.
