Abstract
INTRODUCTION Helicobacter pylori (H. pylori), the most prevalent chronic infection globally, is the major cause of relevant diseases such as gastric cancer, leading to high morbidity and mortality worldwide. Several studies have focused on optimize H. pylori eradication treatment through combination therapies and antibiotic resistance. However, the adverse events profile and its impact, as a primary outcome, remains underexplored.The aim of this review was to summarize the available data on the safety of the most common regimens for H. pylori eradication and its impact on the compliance. AREAS COVERED This review encompassed the published evidence from the years 2008 to 2023 regarding both the safety and compliance for most common H. pylori eradication regimens. The main sources for this review comprised MEDLINE, PubMed, and Cochrane electronic databases. Furthermore, it included a safety analysis of unpublished data from the European Registry on H. pylori management (Hp-EuReg). EXPERT OPINION Poor compliance is correlated with significantly lower cure rates, and this is a unique modifiable source of H. pylori treatment failure. Eradication treatments have become complex, involving multiple drugs and dosing intervals. Thus, patient education is crucial; doctors must explain to the patient about potential temporary and most often harmless side effects.

Nishizawa T, Sano M, Toyoshima O, Suzuki H. Helicobacter pylori Eradication Therapy in Patients with Decreased Renal Function: A Systematic Review. J Clin Med 2024; 13:850. [PMID: 38337544 PMCID: PMC10856467 DOI: 10.3390/jcm13030850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 01/20/2024] [Accepted: 01/29/2024] [Indexed: 02/12/2024] Open
Abstract
Background: There are concerns that Helicobacter pylori eradication therapy may worsen kidney function in patients with decreased renal function. This study aimed to systematically review the literature regarding Helicobacter pylori eradication in patients with renal impairment. Methods: PubMed, the Cochrane Library, and Igaku Chuo Zasshi were searched for comparative studies on H. pylori eradication in patients with renal impairment. Results: Five articles were included in this systematic review. According to a randomized trial comparing a proton pump inhibitor (PPI) + clarithromycin + metronidazole and PPI + clarithromycin + amoxicillin in patients with decreased renal function, the incidence of acute renal failure was significantly lower in PPI + clarithromycin + metronidazole (2%: 1/44) than in PPI + clarithromycin + amoxicillin (18%: 8/44). The eradication rate in PPI + clarithromycin + metronidazole (92.5%) was significantly better than that in PPI + clarithromycin + amoxicillin (76.3%). According to four reports on eradication treatment using PPI + clarithromycin + amoxicillin in patients with and without decreased renal function, the eradication rates and adverse effects were similar in both groups. Regarding dose adjustment, three reports reduced the dose of antibiotics by half in patients with a creatinine clearance of 30 mL/min or less. Conclusions: The regimen with PPIs, clarithromycin, and metronidazole is recommended for renal impairment. The combination of PPIs, clarithromycin, and amoxicillin, at reduced doses depending on the renal function, is also a potential option.

Du RC, Ouyang YB, Lu NH, Hu Y. Research trends on vonoprazan-based therapy for Helicobacter pylori eradication: A bibliometric analysis from 2015 to 2023. Helicobacter 2023; 28:e13012. [PMID: 37515414 DOI: 10.1111/hel.13012] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/10/2023] [Accepted: 07/21/2023] [Indexed: 07/30/2023]
Abstract
BACKGROUND Vonoprazan is an emerging option for the treatment of Helicobacter pylori infection. We aimed to assess the research trends and hotspots of vonoprazan-based therapy for H. pylori eradication through bibliometric analysis. MATERIALS AND METHODS Vonoprazan-based studies for eradicating H. pylori published from 2015 to 2023 were extracted from the Web of Science using a combination of the search terms "H. pylori" and "vonoprazan." Each study was weighted according to the number of included patients. RESULTS A total of 65 studies were included. Japan was the most productive and cooperative country, accounting for 69.2% of publications. Vonoprazan in combination with amoxicillin and clarithromycin (41.8%) was most used for eradicating H. pylori, followed by vonoprazan in combination with amoxicillin (20.4%) and vonoprazan in combination with amoxicillin and metronidazole (19.4%). The eradication rates for first-line vonoprazan-based therapies by intention to treat were: dual therapy (82.9%, 95% CI: 77.7%-88.0%), triple (83.3%, 95% CI: 79.7%-86.8%) and quadruple therapy (91.5%, 95% CI: 85.5%-97.4%), and per protocol: dual therapy (86.1%, 95% CI: 81.5%-90.7%), triple (89.3%, 95% CI: 87.9%-90.6%) and quadruple therapy (94.0%, 95% CI: 88.6%-99.4%). Vonoprazan was superior to proton pump inhibitors in triple therapy regarding empirical therapy (RR = 1.18, 95% CI, 1.14-1.22, p < 0.01) and clarithromycin-resistant group (RR = 1.71, 95% CI, 1.33-2.20, p < 0.01), but there is no significant difference between triple therapy and dual therapy (RR = 1.02, 95% CI, 0.98-1.07, p = 0.33). CONCLUSIONS Vonoprazan has been widely used for H. pylori eradication. Further studies are needed to optimize the best duration and dosage of vonoprazan-based regimens in different regions.

Abstract
Objective Vonoprazan (VPZ), clarithromycin (CAM), metronidazole (MNZ) and VPZ, MNZ, and sitafloxacin (STFX) regimen are all established Helicobacter pylori eradication therapies for patients with penicillin allergy in Japan. However, no study has assessed the efficacy of a VPZ, CAM, and MNZ (VCM) regimen in patients with clarithromycin resistance (CAM-R). We therefore assessed the efficacy of a VCM regimen for treating H. pylori infection in patients with CAM-R and penicillin allergy. Methods Fifty-three patients with penicillin allergy who received H. pylori eradication therapy were retrospectively analyzed. Eight patients received a 7-day proton-pump inhibitor, CAM, and MNZ (PCM) regimen; 35 patients [11 CAM-R, and 10 with clarithromycin sensitivity (CAM-S)] received 7-day VCM regimens; and 10 patients received 7-day VPZ, MNZ, and STFX (VMS) regimens. A 13C-urea breath test was used to determine eradication. The efficacy of eradication was evaluated via both intention-to-treat (ITT) and per-protocol (PP) analyses. Results According to ITT and PP analyses, eradication rates (ERs) with PCM, VCM, and VMS therapies were 50.0% and 50.0%, 94.3% and 100%, and 90% and 90%, respectively. Treatment was successful in all patients with CAM-S. For patients with CAM-R, treatment was successful in 10 patients, and 1 patient discontinued treatment owing to an adverse event. According to ITT and PP analyses, ERs were 90.9% and 100% in CAM-R, and were 100% and 100% in CAM-S, respectively. Conclusion The VCM regimen for H. pylori eradication may be a viable candidate therapy for patients with penicillin allergy, regardless of CAM-R.

Real-world outcomes associated with vonoprazan-based versus proton pump inhibitor-based therapy for Helicobacter pylori infection in Japan. Therap Adv Gastroenterol 2023; 16:17562848231168714. [PMID: 37153499 PMCID: PMC10161293 DOI: 10.1177/17562848231168714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 03/22/2023] [Indexed: 05/09/2023] Open
Abstract
Background Japanese guidelines recommend triple therapy with vonoprazan or a proton pump inhibitor (PPI) in combination with antibiotics to treat Helicobacter pylori (H. pylori) infection. While studies have shown improved eradication rates and reduced costs with vonoprazan versus PPIs, there is little data describing healthcare resource use (HCRU) and treatment patterns. Objectives To compare patients treated with a vonoprazan-based or PPI-based regimen for H. pylori infection in Japan in terms of their characteristics, HCRU, healthcare costs, clinical outcomes, and treatment patterns. Design Retrospective matched cohort. Methods We used data from the Japan Medical Data Center claims database (July 2014-January 2020) to identify adult patients with H. pylori infection and a first observed use of vonoprazan or a PPI in 2015 or later (index date). Patients prescribed a vonoprazan-based or a PPI-based regimen were matched 1:1 using propensity score matching. HCRU, healthcare costs, diagnostic tests, a proxy for H. pylori eradication (i.e. no triple therapy with amoxicillin in combination with metronidazole or clarithromycin >30 days after the index date), and second-line treatment were described during the 12-month follow-up period. Results Among 25,389 matched pairs, vonoprazan-treated patients had fewer all-cause and H. pylori-related inpatient stays and outpatient visits than PPI-treated patients, resulting in lower all-cause healthcare costs [185,378 Japanese yen (JPY) versus 230,876 JPY, p < 0.001]. Over 80% of patients received a post-treatment test for H. pylori. Fewer vonoprazan-treated than PPI-treated patients subsequently received an additional triple regimen for H. pylori infection (7.1% versus 20.0%, p < 0.001) or a prescription for vonoprazan or a PPI as monotherapy (12.4% versus 26.4%, p < 0.001) between 31 days and 12 months after the index date. Conclusion Patients with H. pylori infection who were treated with vonoprazan-based therapy had lower rates of subsequent H. pylori treatment, lower overall and H. pylori-related HCRU, and lower healthcare costs than patients treated with PPI-based therapy.

Abstract
Helicobacter pylori is among the prevalent causes of infections worldwide, and its resistance rate to antibiotics has been rising over time. Amoxicillin is the cornerstone for the treatment regimen. However, the prevalence of penicillin allergy ranges from 4% to 15%. In patients with true allergy, Vonoprazan-Clarithromycin-Metronidazole and bismuth quadruple therapy have demonstrated excellent eradication and high adherence rates. Vonoprazan-based therapy is administered less frequently and may be better tolerated than bismuth quadruple therapy. Therefore, vonoprazan-based therapy may be considered as a first-line therapy if accessible. Bismuth quadruple therapy can be used as the initial therapy when vonoprazan is unavailable. Levofloxacin or sitafloxacin-based regimens achieve a moderately high eradication rate. However, these are associated with potentially serious adverse effects and should only be used when other effective and safer regimens are unavailable. Cephalosporins such as cefuroxime have been used as an alternative to amoxicillin. Microbial susceptibility studies can guide the selection of appropriate antibiotics. PPI-Clarithromycin-Metronidazole fails to achieve a high eradication rate and should be used as a second-line therapy. PPI-Clarithromycin-Rifabutin should not be used because of low eradication rate and frequent adverse reactions. The choice of the most effective antibiotic regimen can enhance clinical outcomes in patients with H. pylori infection and penicillin allergy.

Abstract
Background Vonoprazan, a novel acid-suppressive drug, is non-inferior to proton pump inhibitors (PPIs) for the management of gastric acid-related diseases. However, the safety of vonoprazan has not been systematically evaluated yet. Objectives To elucidate the incidence and type of adverse events (AEs) in patients taking vonoprazan. Design Systematic review and meta-analysis. Data sources and methods PubMed, EMBASE, and Cochrane Library databases were searched for all studies reporting the safety of vonoprazan. The incidences of any AEs, drug-related AEs, serious AEs, AEs leading to drug discontinuation, and common AEs were pooled. Odds ratios (ORs) were calculated to compare the incidence of AEs between patients taking vonoprazan and PPIs. Results Seventy-seven studies were included. The pooled incidences of any AEs, drug-related AEs, serious AEs, and AEs leading to drug discontinuation were 20, 7, 1, and 1%, respectively. The incidences of any AEs (OR = 0.96, p = 0.66), drug-related AEs (OR = 1.10, p = 0.44), serious AEs (OR = 1.14, p = 0.36), and AEs leading to drug discontinuation (OR = 1.09, p = 0.55) were not significantly different between patients taking vonoprazan and PPIs. In subgroup analyses, patients with peptic ulcer disease (PUD) had higher incidences of any AEs, serious AEs, and AEs leading to drug discontinuation than those with gastroesophageal reflux disease (GERD), Helicobacter pylori (H. pylori) infection, and artificial ulcer after gastric endoscopic submucosal dissection (ESD), but patients with H. pylori infection had a higher incidence of drug-related AEs than those with PUD, GERD, and artificial ulcer after gastric ESD. The incidence of AEs was higher in patients taking long-term use of vonoprazan than those taking short-term use of vonoprazan. Conclusion Vonoprazan is well tolerated and shows similar safety compared to PPIs. The safety of vonoprazan may be primarily influenced by its indications and duration.

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

Abstract
Background: Increased antibiotic resistance is one of the major factors contributing to the failure of H. pylori eradication. This study aimed to compare the efficacy and safety of doxycycline and amoxicillin, both critical components for bismuth-based quadruple therapy, for the first-line treatment of H. pylori-infected duodenal ulcers. Methods: An open, randomized case-controlled, multicenter trial was conducted in seven hospitals in China. A total of 184 eligible participants were divided into an IDFB (ilaprazole 5 mg, doxycycline 100 mg, furazolidone 100 mg, and bismuth 220 mg bid) or IAFB (ilaprazole 5 mg, amoxicillin 1000 mg, furazolidone 100 mg, and bismuth 220 mg bid) group for 14 days. Both groups were administrated with ilaprazole 5 mg qd for another 14 days. The main outcome was an H. pylori eradication rate; secondary outcomes were ulcer healing, relief of symptoms, and incidence of adverse effects. Results: The H. pylori eradication rates were 85.9% (95% CI 78.6−93.9) in the IDFB vs. 84.8% (95% CI 77.3−92.3) in the IAFB group in ITT analysis (p > 0.05), and 92.9% (95% CI 87.4−98.5) vs. and 91.8% (95% CI 85.8−97.7) in PP analysis (p > 0.05). The overall ulcer healing rates of IDFB and IAFB were 79.1% and 84.7% (p > 0.05), both effective in relieving symptoms. Only nine participants had adverse reactions in this trial (4/92 in IDFB and 5/92 in IAFB). Conclusion: A bismuth quadruple regimen containing doxycycline or amoxicillin could be an effective and safe treatment for H. pylori eradication, while doxycycline replacement is an alternative for participants with penicillin allergy.

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.

J Clin Biochem Nutr 2022; 70:290-296.

Abstract
In oral endoscopy, linked color imaging (LCI) detects atrophic border and gastric mucosal diseases better than white light imaging (WLI), but its usefulness in transnasal endoscopy has not been fully investigated. Here, we retrospectively compared WLI and LCI using the L*a*b* color space in images from 57 patients aged ≥20 years who had undergone transnasal endoscopy as part of a health check-up from May 2016 to January 2017. We measured color differences at the atrophic/non-atrophic and fundic/pyloric mucosal borders. Gastritis severity scored using the Kyoto classification of gastritis was similar between the two techniques. However, in patients with current and with past Helicobacter pylori infection, color difference at the atrophic border was greater with LCI (21.58 ± 6.97 and 27.34 ± 10.32, respectively) than with WLI [14.42 ± 5.95 (p = 0.004) and 17.9 ± 8.48 (p<0.001)]; in those never infected with Helicobacter pylori, color difference at the fundic/pyloric mucosal border was greater with LCI than with WLI (p<0.001). Because of its enhancement of atrophic border detection, we recommend linked color imaging as the method of choice for transnasal endoscopy in health check-ups, particularly for identifying people at high risk of gastric cancer.

Abstract
Therapy of Helicobacter pylori (H.pylori) requires a combination of antibiotics together with an acid suppressing agent; most treatment regimens include Amoxicillin as one of the antibiotics, which is an important constituent as resistance to it is low. However, allergies to the penicillin group of antibiotics are not uncommon, and treating H.pylori infection in such individuals can be challenging due to the restricted choice of regimens. The aim of this review is to summarise the evidence for therapeutic options in patients with H.pylori infection and penicillin allergy. A literature search was conducted in PubMed for English language publications using the key words ‘Helicobacter’ and ‘treatment’ or ‘therapy‘ and ‘penicillin’ or ‘beta-lactam’ and ‘allergy’ or ‘anaphylaxis’. Eighteen studies were identified that specifically evaluated H.pylori treatment success in penicillin allergic patients. The number of subjects in most of them was low and many were retrospective, uncontrolled, single cohort studies. The most effective option for first-line treatment appears to be Bismuth-based quadruple therapy for 10-14 d. The evidence supports second-line treatment with Levoflaxacin-based triple therapy for 10 d. Patients with persistent H.pylori infection after 2 treatment courses should be considered for testing to confirm penicillin allergy. Further treatment should be guided by the results of H.pylori culture and sensitivity testing.

Abstract
The Indian Society of Gastroenterology (ISG) felt the need to organize a consensus on Helicobacter pylori (H. pylori) infection and to update the current management of H. pylori infection; hence, ISG constituted the ISG's Task Force on Helicobacter pylori. The Task Force on H. pylori undertook an exercise to produce consensus statements on H. pylori infection. Twenty-five experts from different parts of India, including gastroenterologists, pathologists, surgeons, epidemiologists, pediatricians, and microbiologists participated in the meeting. The participants were allocated to one of following sections for the meeting: Epidemiology of H. pylori infection in India and H. pylori associated conditions; diagnosis; treatment and retreatment; H. pylori and gastric cancer, and H. pylori prevention/public health. Each group reviewed all published literature on H. pylori infection with special reference to the Indian scenario and prepared appropriate statements on different aspects for voting and consensus development. This consensus, which was produced through a modified Delphi process including two rounds of face-to-face meetings, reflects our current understanding and recommendations for the diagnosis and management of H. pylori infection. These consensus should serve as a reference for not only guiding treatment of H. pylori infection but also to guide future research on the subject.

Sitafloxacin for Third-Line Helicobacter pylori Eradication: A Systematic Review. J Clin Med 2021; 10:jcm10122722. [PMID: 34202993 PMCID: PMC8234224 DOI: 10.3390/jcm10122722] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 06/04/2021] [Accepted: 06/18/2021] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND AND AIM Sitafloxacin-based therapy is a potent candidate for third-line Helicobacter pylori eradication treatment. In this systematic review, we summarise current reports with sitafloxacin-based therapy as a third-line treatment. METHODS Clinical studies were systematically searched using PubMed, Cochrane library, Web of Science, and the Igaku-Chuo-Zasshi database. We combined data from clinical studies using a random-effects model and calculated pooled event rates, 95% confidence intervals (CIs), and the pooled odds ratio (OR). RESULTS We included twelve clinical studies in the present systematic review. The mean eradication rate for 7-day regimens of either PPI (proton pump inhibitor) or vonoprazan-sitafloxacin-amoxicillin was 80.6% (95% CI, 75.2-85.0). The vonoprazan-sitafloxacin-amoxicillin regimen was significantly superior to the PPI-sitafloxacin-amoxicillin regimen (pooled OR of successful eradication: 6.00; 95% CI: 2.25-15.98, p < 0.001). The PPI-sitafloxacin-amoxicillin regimen was comparable with PPI-sitafloxacin-metronidazole regimens (pooled OR: 1.06; 95% CI: 0.55-2.07, p = 0.86). CONCLUSIONS Although the 7-day regimen composed of vonoprazan, sitafloxacin, and amoxicillin is a good option as the third-line Helicobacter pylori eradication treatment in Japan, the extension of treatment duration should be considered to further improve the eradication rate. Considering the safety concern of fluoroquinolones, sitafloxcin should be used after confirming drug susceptibility.

Abstract
Vonoprazan (VPZ), a new potassium-competitive acid blocker, has been approved and used for Helicobacterpylori eradication in Japan. To date, many studies, as well as several systematic reviews and meta-analyses (MAs), have compared VPZ-based 7-day triple therapy with proton pump inhibitor (PPI)-based therapy. An MA of randomized controlled trials (RCTs) comparing first-line VPZ- with PPI-based triple therapy, the latter featuring amoxicillin (AMPC) and clarithromycin (CAM), found that approximately 30% of patients hosted CAM-resistant H. pylori; however, the reliability was poor because of high heterogeneity and a risk of selection bias. VPZ-based triple therapy is superior to PPI-based triple therapy for patients with CAM-resistant H. pylori, but not for those with CAM-susceptible H. pylori. An MA of non-RCTs found that second-line VPZ-based triple therapies were slightly (~2.6%) better than PPI-based triple therapies (with AMPC and metronidazole). However, the reliability of that MA was also low because of selection bias, confounding variables and a risk of publication bias; in addition, it is difficult to generalize the results because of a lack of data on antibiotic resistance. VPZ-based triple therapy (involving AMPC and sitafloxacin) was more effective than PPI-based triple therapy in a third-line setting, but a confirmatory RCT is needed. Non-RCT studies indicated that VPZ-based triple therapy involving CAM and metronidazole may be promising. Any further RCTs must explore the antibiotic-resistance status when evaluating the possible superiority of a potassium-competitive acid blocker.

Abstract
Background and Aim To assess the efficacy and safety of 7‐day Helicobacter pylori rescue treatment consisting of a vonoprazan (VPZ), metronidazole (MNZ), and sitafloxacin (STFX) regimen (VPZ‐MNZ‐STFX therapy) in patients with penicillin allergy. Methods This was a registered prospective intervention study. Patients with penicillin allergy who were diagnosed with H. pylori infection and had a history of H. pylori eradication were eligible for inclusion. Seventeen patients were prospectively treated with VPZ 20 mg bid, MNZ 250 mg bid, and STFX 100 mg bid for 7 days. Safety was evaluated using a questionnaire on adverse effects. Results The eradication rate of 7‐day VPZ‐MNZ‐SFTX therapy was 88.2% (95% confidence interval: 63.6–98.5%; n = 17) in both intention‐to‐treat and per‐protocol analyses. On the questionnaire, 25% of patients reported experiencing diarrhea, with a score of 2 or 3. All patients undergoing VPZ‐MNZ‐STFX therapy completed 100% of their medication course. Conclusion Rescue H. pylori eradication with VPZ‐MNZ‐STFX therapy is effective and well tolerated in patients with penicillin allergy (UMIN000016335, jRCTs031180133).

Abstract
BACKGROUND Experience in Helicobacter pylori eradication treatment of patients allergic to penicillin is very scarce. A triple combination with a PPI, clarithromycin (C), and metronidazole (M) is often prescribed as the first option, although more recently the use of a quadruple therapy with PPI, bismuth (B), tetracycline (T), and M has been recommended. AIM To evaluate the efficacy and safety of first-line and rescue treatments in patients allergic to penicillin in the "European Registry of H pylori management" (Hp-EuReg). METHODS A systematic prospective registry of the clinical practice of European gastroenterologists (27 countries, 300 investigators) on the management of H pylori infection. An e-CRF was created on AEG-REDCap. Patients with penicillin allergy were analyzed until June 2019. RESULTS One-thousand eighty-four patients allergic to penicillin were analyzed. The most frequently prescribed first-line treatments were as follows: PPI + C + M (n = 285) and PPI + B + T + M (classic or Pylera® ; n = 250). In first line, the efficacy of PPI + C + M was 69%, while PPI + B + T + M reached 91% (P < .001). In second line, after the failure of PPI + C + M, two rescue options showed similar efficacy: PPI + B + T + M (78%) and PPI + C + levofloxacin (L) (71%) (P > .05). In third line, after the failure of PPI + C + M and PPI + C + L, PPI + B + T + M was successful in 75% of cases. CONCLUSION In patients allergic to penicillin, a triple combination with PPI + C + M should not be generally recommended as a first-line treatment, while a quadruple regimen with PPI + B + T + M seems to be a better option. As a rescue treatment, this quadruple regimen (if not previously prescribed) or a triple regimen with PPI + C + L could be used but achieved suboptimal (<80%) results.

Song Z, Fu W, Zhou L. Cefuroxime, levofloxacin, esomeprazole, and bismuth as first-line therapy for eradicating Helicobacter pylori in patients allergic to penicillin. BMC Gastroenterol 2019; 19:132. [PMID: 31345165 PMCID: PMC6659276 DOI: 10.1186/s12876-019-1056-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Accepted: 07/21/2019] [Indexed: 02/06/2023] Open
Abstract
Background Eradicating Helicobacter pylori infection is clinically challenging, notably in cases with penicillin allergy. Cephalosporin could be used in lieu of amoxicillin to eradicate Helicobacter pylori. The current work aimed to assess therapeutic efficacy and safety of a cefuroxime-based quadruple regimen in treatment-naïve individuals with penicillin allergy, as well as patient compliance. Methods In the present prospective single-center cohort study, 152 Helicobacter pylori infected individuals with penicillin allergy received eradication therapy with cefuroxime (500 mg twice/day), levofloxacin (500 mg once/day), esomeprazole (20 mg twice/day) and bismuth potassium citrate (220 mg twice/day; 14 days). Safety and compliance were evaluated 1 to 3 days upon eradication. The urea breath test was carried out 8 to 12 weeks upon eradication for efficacy assessment. Results This quadruple antimicrobial regimen eradicated the pathogen at 85.5% (95% confidence interval (CI) 79.6–90.8%), 88.4% (95% CI 83.0–93.2%) and 90.1% (95% CI 85.2–94.4%) in intention-to-treat, modified intention-to-treat and per-protocol analyses, respectively, with resistance rates of 4.6 and 40.0% in the background of cefuroxime and levofloxacin, respectively. Meanwhile, 21.3% of patients had adverse reactions, but none was serious. A total of 95.3% of patients showed good compliance. Poor compliance and cefuroxime resistance were detected by uni- or multivariate analyses as independent factors predicting therapeutic failure. Eradication rates in patients with dual levofloxacin and cefuroxime susceptibility, isolated levofloxacin resistance, isolated cefuroxime resistance and dual resistance were 97.2, 84.0, 50.0, and 0%, respectively (P = 0.002). Conclusions Cefuroxime, levofloxacin, esomeprazole, and bismuth achieved decent efficacy, safety and compliance as first-line antimicrobial regimen in patients with Helicobacter pylori and penicillin allergy.

Abstract
BACKGROUND AND AIM This was a prospective, randomized trial of the efficacy of vonoprazan-based and proton-pump inhibitor-based 7-day triple regimens with amoxicillin and sitafloxacin as a third-line therapy for eradicating Helicobacter pylori after failure of clarithromycin-based and metronidazole-based first-line and second-line therapy. METHODS We enrolled 63 patients positive for H. pylori in whom first-line and second-line regimens for eradicating failed. Patients were randomized to the V-AS group (vonoprazan 20-mg bid, amoxicillin 750-mg bid, and sitafloxacin 100-mg bid for 7 days) or PPI-AS group (esomeprazole 20-mg bid, rabeprazole 10-mg bid, or lansoprazole 30-mg bid; amoxicillin 750-mg bid; and sitafloxacin 100-mg bid for 7 days). We assessed the outcome of eradication therapy using the 13 C-urea breath test. We evaluated safety using patient questionnaires. This study was registered in the UMIN Clinical Trials Registry (UMIN000016336). RESULTS The intention-to-treat and per-protocol eradication rates of V-AS were 75.8% (95% confidence interval [CI]: 57.7-88.9%) and 83.3% (95% CI: 65.3-94.4%), respectively. The respective eradication rates of PPI-AS were 53.3% (95% CI: 34.3-71.7%) and 57.1% (95% CI: 37.2-75.5%). In per-protocol analyses, the eradication rate of the V-AS group was significantly higher than that of the PPI-AS group (P = 0.043); however, no significant differences were observed in intention-to-treat analyses (P = 0.071). Questionnaire scores did not differ significantly between the groups. CONCLUSIONS The findings suggest that 7-day triple therapy with vonoprazan, amoxicillin, and sitafloxacin is more effective than proton-pump inhibitor, amoxicillin, and sitafloxacin as a third-line regimen for eradicating H. pylori.

Abstract
Proton pump inhibitors are commonly utilized for the treatment of gastric acid-related diseases, such as gastroesophageal reflux disease, peptic ulcer disease, and Helicobacter pylori infection, and for the prevention of low-dose aspirin or nonsteroidal anti-inflammatory drug-induced peptic ulcers. Vonoprazan is a first-in-class potassium-competitive acid blocker, which has distinct advantages compared to other conventional proton pump inhibitors in terms of the efficacy for acid suppression. Due to its strong gastric acid suppression capabilities, vonoprazan serves as an effective drug for the treatment of gastroesophageal reflux disease and H. pylori infection.

Abstract
Complete eradication of Helicobacter pylori is important for preventing the development of gastric cancer. The outcome of H. pylori eradication therapy is mainly dependent on bacterial susceptibility to antimicrobial agents and potent neutralization of intragastric pH across 24 h, especially when using acid-sensitive antimicrobial agents such as clarithromycin (CLR), amoxicillin and sitafloxacin. However, conventional regimens comprising twice-daily doses (bid) of proton pump inhibitors (PPIs) are generally insufficient for maintaining the required gastric acid secretion for 24 h for successful eradication in all H. pylori-positive patients. Further, the increasing prevalence of CLR-resistant strains with each year has led to a decrease in eradication rates of first-line PPI- and CLR-containing therapies in developed countries, including Japan. In 2015, the potassium-competitive acid blocker vonoprazan (VPZ) became clinically available in Japan. VPZ competitively inhibits H+/K+-ATPase activity more potently than PPIs (e.g., omeprazole, lansoprazole, rabeprazole, pantoprazole, and esomeprazole). Therefore, a VPZ-containing H. pylori eradication regimen is expected to increase the eradication rate compared with conventional regimens containing a standard dose of PPI. In fact, a recent meta-analysis that investigated the efficacy of first-line eradication therapy showed that a VPZ-containing regimen achieved a higher eradication rate than a PPI-containing regimen. While the Maastricht V/Florence Consensus Report recommends selecting a bismuth or non-bismuth quadruple therapy and concomitant therapy for patients living in areas with high prevalence of CLR resistance, a VPZ-containing regimen demonstrates effectiveness for patients infected with CLR-resistant strains and patients living in areas where the prevalence of CLR-resistant strains is >15%. As a next step, studies are needed to determine the factors affecting the clinical outcome of VPZ-containing therapy and optimal VPZ-containing alternative regimens for tailored treatments. In this review, we summarize the advantages and disadvantages of VPZ in H. pylori eradication therapy.

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
BACKGROUND The eradication rate of vonoprazan-based first-line triple therapy (combined with clarithromycin and amoxicillin) (V-AC) was reported to be 97.6% in patients with clarithromycin (CAM)-susceptible Helicobacter pylori in a phase III study, whereas our real-world, prospective, multicenter cohort study yielded an eradication rate <90%. OBJECTIVE To validate the eradication rate of V-AC using CAM-susceptible testing in a multicenter, prospective, randomized trial. METHODS We included 147 treatment-naïve H. pylori-positive patients [41 with CAM-resistant infections and 106 with CAM-susceptible infections]. The CAM-susceptible group patients were randomized to either the V-AC group (vonoprazan 20 mg bid, amoxicillin 750 mg bid, and clarithromycin 200 or 400 mg bid) or PPI-AC group (lansoprazole 30 mg, rabeprazole 10 mg, or esomeprazole 20 mg bid; amoxicillin 750 mg bid; and clarithromycin 200 or 400 mg bid). All CAM-resistant H. pylori were eradicated by V-AC, as measured by the urea breath test around 8 weeks after eradication. Safety was evaluated by patient questionnaires. RESULTS The intention-to-treat and per-protocol eradication rates of V-AC in the CAM-susceptible H. pylori-infected patients were 87.3% (95% confidence interval 75.5%-94.7%) and 88.9% (77.4%-95.8%). The respective eradication rates of PPI-AC were 76.5% (62.5%-87.2%) and 86.7% (73.2%-94.9%). No significant difference was observed between the V-AC and PPI-AC regimes in terms of the intention-to-treat (P = .21) or per-protocol (P = .77) analyses. The questionnaire scores did not differ significantly between the groups. Both the intention-to-treat and per-protocol eradication rates of V-AC in the CAM-resistant patients were 82.9% (67.9%-92.8%). CONCLUSION The eradication rate of V-AC treatment in the CAM-susceptible H. pylori-infected patients was <90%, as was that by PPI-AC, thus V-AC is not ideal regimen in CAM-susceptible H. pylori. However, the 82.9% eradication rate of V-AC in the CAM-resistant infections may indicate the potential of V-AC with modified dose, dosing interval, and treatment duration. (UMIN000016337).

Abstract
Although proton pump inhibitors (PPIs) have been used widely, acid-related diseases are still associated with a huge burden on the health care system. Recently, the efficacy and safety of a new acid suppressant named vonoprazan in the treatment of acid-related diseases have been evaluated by a series of studies. As a novel potassium-competitive acid blocker, vonoprazan may provide reversible acid suppression by preventing K+ from binding to gastric H+/K+-ATPase. It has been clinically used for the short-term treatment of gastroesophageal reflux disease (GERD), peptic ulcer disease and Helicobacter pylori (H. pylori) infection in Japan. The healing rate of GERD and gastric ulcers by vonoprazan is more than 95 and 90%, respectively; also, it is effective in curing PPI-resistant GERD. It increases H. pylori eradication rate to more than 88% as part of both first-line and second-line therapy. It is also effective in the eradication of clarithromycin-resistant H. pylori strains. All of these short-term studies show vonoprazan is safe and well-tolerated. As a safe and effective acid inhibitor, vonoprazan might be a novel alternative in the treatment of acid-related diseases.

Abstract
BACKGROUND Vonoprazan (VPZ) is a novel acid suppressant that has been used in Helicobacter pylori (H. pylori) eradication therapies in recent years. However, the efficacy and safety of VPZ vs proton-pump inhibitor (PPI) in H. pylori eradication therapies remain controversial. OBJECTIVE To perform a meta-analysis in order to assess the efficacy and safety of VPZ vs PPI for H. pylori eradication. MATERIALS AND METHODS The PubMed, EMBASE, and Cochrane Library databases were searched up to July 10, 2017, for relevant randomized controlled trials (RCTs) and nonrandomized clinical studies (NRCTs). The pooled eradication rate (ER) and pooled occurrence rates of adverse events were used to compare the efficacy and safety of VPZ - and PPI-containing regimens. RESULT A total of 14 studies with 14 636 patients were included in this meta-analysis. The results showed that the pooled ER of VPZ -containing regimens was much higher than that of PPI-containing regimens when used as first-line therapies. This difference was significant for both intention-to-treat (85.1% vs 68.0%, P < .00001) and per-protocol analyses (89.0% vs 74.2%, P < .00001). Moreover, subgroup analysis indicated significant superiority of VPZ in both patients with clarithromycin-resistant strains (81.5% vs 40.9%, P < .00001) and those with clarithromycin-susceptible strains (94.9% vs 89.6%, P = .006). However, VPZ did not show superiority to PPI as part of a second-line triple therapy based on both intention-to-treat (83.4% vs 82.0%, P = .79) and per-protocol analyses (89.3% vs 90.1%, P = .06). Finally, RCT subgroup analysis showed the safety of VPZ -containing regimens to be better than PPI-containing regimens (26.4% vs 33.3%, P = .008), whereas there was no significant difference in this regard for the NRCT subgroup analysis (5.7% vs 4.7%, P = .08). CONCLUSIONS The efficacy of VPZ is superior to PPI in first-line H. pylori triple eradication therapies but not in second-line therapies. The safety of VPZ -containing regimens appears to be equal or even superior to that of PPI. However, most reports included in this study had low levels of evidence. Hence, adequate and high-quality RCTs will be needed to support our results.

Abstract
Aim To assess the efficacy of 7-day first-line Helicobacter pylori eradication with vonoprazan (VPZ), clarithromycin (CAM), and metronidazole (MNZ) in patients with penicillin allergy. Methods Patients with penicillin allergy, diagnosed with Helicobacter pylori infection and did not have history of Helicobacter pylori eradication, were eligible for the study. Twenty patients were prospectively treated with 20 mg VPZ twice daily, 200 or 400 mg CAM twice daily, and 250 mg MNZ twice daily for 7 days. We also collected the data from 30 patients retrospectively treated with proton pump inhibitor (PPI), CAM, and MNZ. Safety was evaluated in patients completing an adverse effect questionnaire. Results Both the intention-to-treat and per-protocol effectiveness of VPZ-based eradication were 100% (95% CI: 86.1–100%; n = 20). The eradication rates of PPI-based regimen were 83.3% (95% CI: 65.3–94.4%) in the ITT and 82.7% (95% CI: 64.2–94.2%) in the PP analyses. Abdominal fullness was more frequent in VCM compared to PCM. However, all patients with VCM regimen had taken 100% of their course of medication. Conclusion Triple therapy with VPZ, CAM, and MNZ is well tolerated and effective for eradicating Helicobacter pylori in patients allergic to penicillin. This study was registered in the UMIN Clinical Trials Registry as UMIN000016335.

Abstract
This review summarizes important studies regarding Helicobacter pylori therapy published from April 2016 to April 2017. The main themes that emerge involve studies assessing the efficacy of bismuth and nonbismuth quadruple regimens. While in recent years, much of the emphasis on the use of bismuth has focussed on its utility in a second-line setting, an increasing number of studies this year have shown excellent efficacy in first-line therapy. The efficacy of bismuth as a second-line after sequential and concomitant therapy was particularly noteworthy. Antibiotic resistance was more intensely studied this year than for a long time, and definite trends are presented regarding an increase in resistance, including the fact that clarithromycin resistance in particular is now at a level where the continued use of clarithromycin triple therapy first-line as a mainstream treatment is not recommended. Another exciting trend to emerge this year is the utility of vonoprazan as an alternative to PPI therapy, especially in resistant and difficult-to-treat groups.

Abstract
INTRODUCTION Proton pump inhibitors (PPIs) display a number of limitations and unmet clinical needs that have prompted the development of novel drugs to improve the outcomes of acid-related diseases, including the eradication of H. pylori. In this context, a new synthesized potassium-competitive acid blocker (P-CAB), vonoprazan, showed higher suppression of gastric acid secretion. Areas covered: This review discusses the current knowledge regarding the efficacy of vonoprazan in the treatment of acid-related diseases, with a particular focus on its use in Helicobacter pylori eradication. Expert opinion: Vonoprazan showed some advantages over PPIs in terms of the pharmacokinetic and pharmacodynamic profile: fast onset of action without requiring acid activation and specific administration timing, more potent and prolonged inhibition of acid secretion, including a better nighttime acid control, and a less antisecretory variability. Recent evidence suggests that vonoprazan can be preferred to PPIs as maintenance therapy for reflux esophagitis and eradication of Helicobacter pylori owing to its stronger antisecretory effect. Moreover, vonoprazan displays favorable safety and tolerability profiles, even though long-term studies on the effects of vonoprazan are required.
