Abstract
BACKGROUND We aimed to evaluate the validity of self-administered questionnaire surveys and face-to-face interview surveys for the detection of Helicobacter pylori eradication therapy. METHODS Participants were a cohort, aged 40-74 years, living in three different locations of Japan, who took part in the baseline survey (2011-2012) of the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT). Five years after the baseline survey, a questionnaire and interview survey were independently conducted to determine the history of Helicobacter pylori eradication treatment over the 5-year period. Prescription of Helicobacter pylori eradication medications in national insurance claims data from the baseline survey to the 5-year survey was used as a reference standard. RESULTS In total, 15,760 questionnaire surveys and 8,006 interview surveys were included in the analysis. There were 3,471 respondents to the questionnaire and 2,398 respondents to the interview who reported having received Helicobacter pylori eradication treatment within the past 5 years. Comparison of the questionnaire survey to national insurance claims data showed a sensitivity of 95.1% (2,213/2,328), specificity of 90.6% (12,174/13,432), positive predictive value of 63.8% (2,213/3,471), negative predictive value of 99.1% (12,174/12,289), and Cohen's Kappa value of 0.71. Respective values of the interview survey were 94.4% (1,694/1,795), 88.7% (5,507/6,211), 70.6% (1,694/2,398), 98.2% (5,507/5,608), and 0.74. CONCLUSION Both the questionnaire and the interview showed high sensitivity, high specificity, and good agreement with the insurance claim prescriptions data. Some participants may have received eradication treatment without going through the public insurance claim database, resulting in a low positive predictive value.

Abstract
BACKGROUND With the increasing prevalence of antibiotic resistance, real-world data on the optimal empirical second-line therapy for Helicobacter pylori are still limited. OBJECTIVES To evaluate the real-world efficacy of various second-line therapies for H. pylori. PATIENTS AND METHODS This was a retrospective population-based cohort study of all H. pylori-infected patients who had received the second-line treatment after the failure of primary clarithromycin triple therapy in Hong Kong between 2003 and 2018. The retreatment success rates of different second-line therapies were evaluated. RESULTS A total of 7591 patients who received second-line treatment were included. Notably, the most commonly prescribed regimen was still clarithromycin triple therapy, but the frequency of use had decreased from 59.5% in 2003-06 to 28.7% in 2015-18. Concomitant non-bismuth quadruple therapy had emerged as the commonest regimen (from 3.3% to 43.9%). In a validation analysis, the sensitivity and specificity of retreatment-inferred second-line treatment failure were 88.3% and 97.1%, respectively. The overall success rate of second-line therapies was 73.6%. Bismuth quadruple therapy had the highest success rate of 85.6%, while clarithromycin triple therapy had the lowest success rate of 63.5%. Specifically, bismuth/metronidazole/tetracycline quadruple, metronidazole/tetracycline triple, levofloxacin/metronidazole/tetracycline quadruple, rifabutin/amoxicillin triple and amoxicillin/levofloxacin triple therapies had relatively higher success rates over 80%. Age, treatment duration, baseline conditions and first-line treatment used were associated with success rate. CONCLUSIONS Bismuth quadruple therapy was the most effective second-line regimen for H. pylori in this real-world study. Despite a very low success rate, clarithromycin-containing triple therapies were still commonly used as second-line regimens.

Abstract
BACKGROUND In East Asia, Helicobacter pylori ( H. pylori ) infection and related diseases are common, primarily during childhood and adolescence. The rates of primary antibiotic resistance in H. pylori among East Asian children and adolescents have not been extensively explored; few relevant systematic reviews or meta-analyses have been conducted. We evaluated the rates of antibiotic resistance in H. pylori among East Asian children and adolescents, with the goal of facilitating individualized treatment recommendations. METHODS We searched PubMed, Embase, and the Cochrane Library for studies in any language published up to February 2023 that explored antibiotic resistance in H. pylori among East Asian children and adolescents. We used MeSH and non-MeSH terms related to the topic, including terms related to children, adolescents, antibiotic resistance, H. pylori , and nations or regions. Additionally, we reviewed the reference lists of relevant articles. Studies that matched our strict predefined eligibility criteria were included in the screening process. Using established assessment methods, we evaluated the quality of the included studies. RESULTS We identified 15 observational studies involving 4831 H. pylori isolates, all published between 2001 and 2022. There was substantial primary antibiotic resistance in H. pylori isolates from East Asian children and adolescents. The rates of primary resistance were 51% (95% confidence interval [CI]: 40-62%) for metronidazole; 37% (95% CI: 20-53%) for clarithromycin; 19% (95% CI: 11-28%) for levofloxacin; and less than 3% each for amoxicillin, tetracycline, and furazolidone. Subgroup analysis revealed a prominent increase in metronidazole resistance over time. Clarithromycin and levofloxacin resistance rates fluctuated between 2005 and 2015, then remained stable; other antibiotic resistance rates were generally stable. Metronidazole, clarithromycin, and levofloxacin resistance rates were significantly higher in the Chinese mainland than in other East Asian regions. The rates of dual and multiple antibiotic resistance were 28% (95% CI: 21-36%) and 10% (95% CI: 7-14%), highlighting the potential for diverse resistance patterns. CONCLUSIONS H. pylori isolates from East Asian children and adolescents exhibit high levels of metronidazole and clarithromycin resistance, particularly in the Chinese mainland. The non-negligible rates of dual and multiple resistance highlight the complexity of this problem. REGISTRATION PROSPERO, No. CRD42023402510.

Abstract
INTRODUCTION Helicobacter pylori is a major risk factor for gastric cancer. In addition to eradication therapy, early-phase detection of gastric cancer through screening programs using high-vision endoscopy is also widely known to reduce mortality. Although European and US guidelines recommend evaluation of atrophy and intestinal metaplasia by high-vision endoscopy and pathological findings, the guideline used in Japan - the Kyoto classification of gastritis - is based on endoscopic evaluation, and recommends the grading of risk factors. This system requires classification into three endoscopic groups: H. pylori-negative, previous H. pylori infection (inactive gastritis), and current H. pylori infection (active gastritis). Major endoscopic findings in active gastritis are diffuse redness, enlarged folds, nodularity, mucosal swelling, and sticky mucus, while those in H pylori-related gastritis - irrespective of active or inactive status - are atrophy, intestinal metaplasia, and xanthoma. AREAS COVERED This review describes the endoscopic characteristics of current H. pylori infection, and how characteristic endoscopic findings should be evaluated. EXPERT OPINION Although the correct evaluation of endoscopic findings related to H. pylori remains necessary, if findings of possible infection are observed, it is important to diagnose infection by detection methods with high sensitivity and specificity, including the stool antigen test and urea breath test.

Characteristics of Helicobacter pylori Eradication Therapy in Patients 80 Years or Older Living in a Metropolitan Area: A Multicenter Retrospective Study. Helicobacter 2024; 29:e13125. [PMID: 39152662 DOI: 10.1111/hel.13125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 07/27/2024] [Accepted: 07/29/2024] [Indexed: 08/19/2024]
Abstract
BACKGROUND The situation of Helicobacter pylori eradication therapy has been changing over time, owing to increases in antimicrobial-resistant strains, lifestyle improvements, and changes in indications for eradication. In Japan, eradication therapy is now available to all H. pylori-positive patients under the medical insurance system, and the potassium-competitive acid blocker vonoprazan has been used for eradication from 2015. Recently, with the aging of society, opportunities to provide eradication to elderly patients are increasing, but the current status and effectiveness of eradication in elderly patients remains unclear. Therefore, we aimed to investigate the trends of H. pylori eradication in a metropolitan area to determine the factors associated with successful H. pylori eradication in elderly patients older than 80 years. METHODS Trends in the eradication rates of patients who received first- or second-line eradication at 20 hospitals in the Tokyo metropolitan area from 2013 to 2023 were investigated. RESULTS The eradication rates in the per-protocol analysis were 82.3% (95% confidence interval [CI]: 81.2%-83.2%) for the first-line treatment (n = 6481), and 87.9% (86.9%-88.9%) for the second-line treatment (n = 4899). Multivariate analysis showed that independent factors for successful eradication in the first-line treatment were an age of older than 80 years (OR: 0.606; 95% CI: 0.448-0.822), peptic ulcers (vs. atrophic gastritis: 3.817; 3.286-4.433), and vonoprazan (vs. proton pump inhibiters (PPIs), 3.817; 3.286-4.433), and an age of older than 80 years (0.503; 0.362-0.699) and vonoprazan (1.386; 1.153-1.667) in the second-line treatment. CONCLUSION After 2015, the eradication rate of both first- and second-line therapies were maintained at a higher level than before 2015, owing to the use of vonoprazan. As the H. pylori eradication rate in patients older than 80 years was low, an effective strategy for these patients needs to be developed in the future.

Abstract
OBJECTIVES High-resolution manometry (HRM) and esophagography are used for achalasia diagnosis; however, achalasia phenotypes combining esophageal motility and morphology are unknown. Moreover, predicting treatment outcomes of peroral endoscopic myotomy (POEM) in treatment-naïve patients remains an unmet need. METHODS In this multicenter cohort study, we included 1824 treatment-naïve patients diagnosed with achalasia. In total, 1778 patients underwent POEM. Clustering by machine learning was conducted to identify achalasia phenotypes using patients' demographic data, including age, sex, disease duration, body mass index, and HRM/esophagography findings. Machine learning models were developed to predict persistent symptoms (Eckardt score ≥3) and reflux esophagitis (RE) (Los Angeles grades A-D) after POEM. RESULTS Machine learning identified three achalasia phenotypes: phenotype 1, type I achalasia with a dilated esophagus (n = 676; 37.0%); phenotype 2, type II achalasia with a dilated esophagus (n = 203; 11.1%); and phenotype 3, late-onset type I-III achalasia with a nondilated esophagus (n = 619, 33.9%). Types I and II achalasia in phenotypes 1 and 2 exhibited different clinical characteristics from those in phenotype 3, implying different pathophysiologies within the same HRM diagnosis. A predictive model for persistent symptoms exhibited an area under the curve of 0.70. Pre-POEM Eckardt score ≥6 was the greatest contributing factor for persistent symptoms. The area under the curve for post-POEM RE was 0.61. CONCLUSION Achalasia phenotypes combining esophageal motility and morphology indicated multiple disease pathophysiologies. Machine learning helped develop an optimal risk stratification model for persistent symptoms with novel insights into treatment resistance factors.

Bismuth-Containing Quadruple Therapy for Helicobacter pylori Eradication: A Randomized Clinical Trial of 10 and 14 Days. Dig Dis Sci 2024; 69:2540-2547. [PMID: 38700630 DOI: 10.1007/s10620-024-08460-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 04/20/2024] [Indexed: 07/19/2024]
Abstract
BACKGROUND Bismuth-containing quadruple therapy is the first-line treatment for eradicating Helicobacter pylori (H. pylori). The optimal duration for H. pylori eradication using bismuth-containing quadruple therapy remains controversial. Therefore, we aimed to compare the clinical effects of the 10- and 14-day bismuth-containing quadruple treatment regimen to eradicate H. pylori. METHODS Treatment-naïve patients with H. pylori infection (n = 1300) were enrolled in this multicenter randomized controlled study across five hospitals in China. They were randomized into 10- or 14-day treatment groups to receive bismuth-containing quadruple therapy as follows: vonoprazan 20 mg twice daily; bismuth 220 mg twice daily; amoxicillin 1000 mg twice daily; and either clarithromycin 500 mg twice daily or tetracycline 500 mg four times daily. At least 6 weeks after treatment, we performed a 13C-urea breath test to evaluate H. pylori eradication. RESULTS The per-protocol eradication rates were 93.22% (564/605) and 93.74% (569/607) (p < 0.001) and the intention-to-treat eradication rates were 88.62% (576/650) and 89.38% (581/650) (p = 0.007) for the 10- and 14-day regimens, respectively. Incidence of adverse effects was lower in patients who received 10- vs. 14 days of treatment (22.59% vs. 28.50%, p = 0.016). We observed no significant differences in the compliance to treatment or the discontinuation of therapy because of severe adverse effects between the groups. CONCLUSION Compared with the 14-day bismuth-containing quadruple regimens, the 10-day regimen demonstrated a non-inferior efficacy and lower incidence of adverse effects. Therefore, the 10-day regimen is safe and tolerated and could be recommended for H. pylori eradication (NCT05049902).

Kowada A. Cost-Effectiveness of Population-Based Helicobacter pylori Screening With Eradication for Optimal Age of Implementation. Helicobacter 2024; 29:e13120. [PMID: 39138610 DOI: 10.1111/hel.13120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2024] [Revised: 07/20/2024] [Accepted: 07/23/2024] [Indexed: 08/15/2024]
Abstract
BACKGROUND Helicobacter pylori screening with eradication reduces gastric cancer (GC) development. However, it was unknown at what age the H. pylori screening should be implemented to achieve the greatest benefits at the least cost. This study aimed to determine the optimal age of H. pylori screening for primary GC prevention. MATERIALS AND METHODS A state transition model for a hypothetical cohort of 15-year-olds from a healthcare payer perspective on a lifetime horizon was developed. Nine ages for H. pylori testing were considered: 15, 18, 20, 30, 40, 50, 60, 70, and 80 years. H. pylori screening was compared with no screening and annual, biennial, and triennial endoscopies starting at age 50. The main outcomes were costs, quality-adjusted life-years (QALYs), life expectancy life-years (LYs), incremental cost-effectiveness ratios, GC cases, stage I GC cases, and GC-related deaths. One-way, two-way, and probabilistic sensitivity analyses were performed to assess the uncertainty of the parameters. RESULTS All H. pylori screenings at ages 15-80 were more cost-effective than all endoscopies and no screening. H. pylori screening at age 15 yielded the greatest cost-saving and benefits. The cost-effectiveness was sensitive to the adherence rate of H. pylori screening at age 15. Cost-effectiveness acceptability curves showed that H. pylori screening at age 15 was 99.6% cost-effective at a willingness-to-pay threshold of US$50,000 per QALY gained. Compared with no screening and biennial endoscopy in 15.6 million 15-year-olds from 2022 to 2037, respectively, H. pylori screening at age 15 saves US$9.70 million and US$2.39 billion, increases 1.26 million QALYs with 1312 LYs and 651 LYs, prevents 436 GC cases with 254 stage I GC cases and 305 stage I GC cases, and avoids 176 GC-related deaths and 72 GC-related deaths. CONCLUSIONS The optimal age for population-based H. pylori screening at ages 15-80 is the youngest, 15 years old. Shifting population-based H. pylori screening to younger people will reduce GC morbidity and mortality worldwide, along with a detailed investigation of the feasibility and long-term consequences of H. pylori eradication at a young age.

Abstract
Gastrointestinal bleeding (GIB) is a significant public health concern, predominantly associated with high morbidity. However, there have been no reports investigating the trends of GIB in Japan using nationwide data. This study aims to identify current trends and issues in the management of GIB by assessing Japan's national data. We analyzed National Database sampling data from 2012 to 2019, evaluating annual hospitalization rates for major six types of GIB including hemorrhagic gastric ulcers, duodenal ulcers, esophageal variceal bleeding, colonic diverticular bleeding, ischemic colitis, and rectal ulcers. In this study, hospitalization rates per 100,000 indicated a marked decline in hemorrhagic gastric ulcers, approximately two-thirds from 41.5 to 27.9, whereas rates for colonic diverticular bleeding more than doubled, escalating from 15.1 to 34.0. Ischemic colitis rates increased 1.6 times, from 20.8 to 34.9. In 2017, the hospitalization rate per 100,000 for colonic diverticular bleeding and ischemic colitis surpassed those for hemorrhagic gastric ulcers (31.1, 31.3, and 31.0, respectively). No significant changes were observed for duodenal ulcers, esophageal variceal bleeding, or rectal ulcers. The findings of this study underscore a pivotal shift in hospitalization frequencies from upper GIB to lower GIB in 2017, indicating a potential shift in clinical focus and resource allocation.

Abstract
Helicobacter pylori is a prevalent bacterial pathogen globally, implicated in various gastrointestinal disorders. Current recommended antibiotic therapies for H. pylori infection have been proven to be therapeutically insufficient, with low eradication rates and high recurrence rates. Emerging evidence suggests that antibiotic therapy for H. pylori can lead to gastrointestinal and subsequent vaginal dysbiosis, posing challenges for conventional antibiotic approaches. Thus, this article proposes a novel probiotic therapy involving simultaneous oral and intra-vaginal probiotic administration alongside antibiotics for H. pylori treatment, aiming to enhance eradication rates and mitigate dysbiosis. We begin by providing an overview of gastrointestinal and vaginal microbiota and their interconnectedness through the vagina-gut axis. We then review the efficacy of current antibiotic regimens for H. pylori and discuss how antibiotic treatment impacts the vaginal microenvironment. To explore the feasibility of this approach, we evaluate the effectiveness of oral and intra-vaginal probiotics in restoring normal microbiota in the gastrointestinal and vaginal tracts, respectively. Additionally, we analyze the direct mechanisms by which oral and intra-vaginal probiotics act on their respective tracts and discuss potential cross-tract mechanisms. Considering the potential synergistic therapeutic effects of probiotics in both the gastrointestinal and vaginal tracts, dual-channel probiotic therapy holds promise as a more effective approach for H. pylori eradication and dysbiosis mitigation, presenting a novel concept in the collaborative treatment of gastrointestinal and genital disorders.

Abstract
The prevalence of Helicobacter pylori (H. pylori), a pathogen, has decreased globally in the last decade. To date, the management of H. pylori has focused on a reactive approach, whereby those diagnosed are treated with antimicrobials and acid suppression in combination. This review article provides an overview of the shift in the management of H. pylori from a reactive approach towards a proactive 'screen and treat' approach; the article reflects the current pharmacological landscape for H. pylori treatment by exploring similarities such as the first-line prescription of quadruple therapy in most countries and provides a summary table of the best practice guidance from Europe, Asia, and North America. It explores significant ongoing challenges in management, such as rising antimicrobial resistance rates, and explores a potential 'work smart' approach to antimicrobial susceptibility testing. We explore the role of registry databases in providing data on treatment efficacy and safety and how they can support a strategic approach to H. pylori treatment. We question if such a database's availability, update, and regular audit should serve as a key quality indicator in a population screening programme. Despite a call for vaccination against H. pylori and decades of research, not many have made it to a phase-three clinical trial. We explore the challenges that have complicated the development of such a vaccine, such as the genetic diversity of H. pylori, immunotolerance, and limitations of mouse models in research; we reflect on how these challenges are contributing to a low likelihood of having a vaccine in the short-medium term. Lastly, it explores the heterogeneity in research on probiotics and their role as an adjunct in the management of H. pylori.

Abstract
Helicobacter pylori eradication therapy reduces the risk of gastric cancer. However, it is unclear whether the severity of risk factors for gastric cancer such as atrophy and intestinal metaplasia are reduced after eradication in the long term. We aimed to study long-term changes in endoscopic risk factors for gastric cancer up to 20 years post-eradication. The endoscopic severity of gastritis according to the Kyoto Classification of Gastritis in 167 patients was retrospectively evaluated over an average follow-up 15.7 years. A significant improvement in mean total gastric cancer risk score (4.36 ± 1.66 to 2.69 ± 1.07, p < 0.001), atrophy (1.73 ± 0.44 to 1.61 ± 0.49, p = 0.004), and diffuse redness (1.22 ± 0.79 to 0.02 ± 0.13, p < 0.001) was observed compared to baseline in the Eradication group. However, there was no change in the never infection and current infection groups. The frequency of map-like redness increased over time until 15 years (3.6% to 18.7%, p = 0.03). The Cancer group had significantly higher risk scores at all time points. Endoscopic atrophy significantly improved in eradicated patients over long-term, suggested that eradication is one of the key elements in gastric cancer prevention. Individualized surveillance strategies based on endoscopic gastritis severity before eradication may be important for those at risk of gastric cancer.

Helicobacter pylori antibiotic resistance profile in Chinese children with upper gastrointestinal symptoms and a literature review for developing personalized eradicating strategies. Front Pharmacol 2024; 15:1392787. [PMID: 38887553 PMCID: PMC11180794 DOI: 10.3389/fphar.2024.1392787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 05/13/2024] [Indexed: 06/20/2024] Open
Abstract
Background: H. pylori (Helicobacter pylori) infections typically occur in early childhood. Although the prevalence of H. pylori in children is lower than that in adults, the eradication rate of this infection in children is relatively low because of resistance. In this study, we analyzed personalized treatment strategies to achieve treatment goals based on H. pylori resistance characteristics. This retrospective single-center study was conducted between January 2019 and December 2022 and enrolled 1,587 children who presented with upper gastrointestinal symptoms and underwent endoscopy. H. pylori culturing and antimicrobial susceptibility testing were performed. Results: Culture-positive results for H. pylori were obtained in 535 children. The resistance rates to clarithromycin (CLA), metronidazole (MET), and levofloxacin (LEV) were 39.8%, 78.1%, and 20.2%, respectively. None of the isolates were resistant to tetracycline (TET), amoxicillin (AMO), or furazolidone (FZD). Double resistance rates to CLA + MET, CLA + LEV, and MET + LEV were 19.1%, 3.0%, and 5.8%, respectively. Notably, triple-resistant to CLA + MET + LEV was 9.7%. Based on susceptibility tests, individualized triple therapy [proton pump inhibitor (PPI) +AMO + CLA/MET] was selected for 380 children with H. pylori sensitive to MET and/or CLA. In 155 children resistant to CLA and MET, bismuth-based quadruple therapy was recommended; for unable to receive bismuth, concomitant therapy was recommended for 14 children (<8 years of age); triple therapy with TET was recommended for 141 children (>8 years of age), with 43 children (>14 years of age) requiring FZD rather than TET. Conclusion: Resistance to H. pylori in Chinese children was relatively poor. Personalized therapy regimens should be based on susceptibility tests and avoided factors associated with treatment failure.

Abstract
BACKGROUND Previous studies have shown the associations between smoking and failure to eradicate Helicobacter pylori (H. pylori), but less is known about the impact of secondhand tobacco smoke (SHS) on H. pylori eradication. METHODS Between July 2022 to July 2023, 646 patients who received proton pump inhibitor (PPIs) as first-line H. pylori eradication therapy were recruited for the study. Information was obtained via the hospital database and a telephone questionnaire. Univariate and multivariate regression analysis were used to examine risk factors of H. pylori eradication failure. RESULTS This was a single-center retrospective study consisting of 646 patients who received PPIs as first-line H. pylori eradication therapy. This included 122 smokers, 165 never-smokers with SHS, and 359 never-smokers with no SHS exposure. Compared with subjects in the "eradication success" group, those in the "eradication failure" group tended to have higher prevalence of smoke consumption and have higher prevalence of SHS exposure. In binary logistic regression analysis, smoking (OR 3.409, 95 % CI: 1.782- 6.522, P < 0.001) and SHS (OR 3.188, 95 % CI: 1.726-5.886, P < 0.001) were independent predictors of eradication failure. In addition, never-smokers with SHS exposure and smoking had similar effects on H. pylori eradication (OR, 0.893; 95 % CI, 0.464 to 1.717, P value = 0.734). CONCLUSION Both smoking and SHS are independent risk factors for H. pylori eradication failure. Furthermore, the impact of SHS is not inferior to smoking.

Abstract
Objective Of the highly accurate tests for current Helicobacter pylori infection, the urea breath test (UBT) and stool antigen test (SAT) are noninvasive and do not require endoscopy. We conducted a prospective study to evaluate the accuracy of the newly developed SAT in a medical checkup setting. Methods The accuracy of the proposed SAT was examined by determining H. pylori infection status based on a history of eradication therapy, endoscopic H. pylori infection diagnosis, and blood tests (serum H. pylori antibody, serum PG II) in individuals undergoing esophagogastroduodenoscopy (EGD) during a health checkup. Results The new SAT showed 97.3% (108/111) sensitivity for those "currently infected," as well as 99.3% (530/534), 98.0% (402/410), and 98.7% (932/944) specificity for those "never infected," those "previously infected," and those "never/previously infected", respectively. Conclusion The newly developed H. pylori SAT may be useful for diagnosing H. pylori infection. Patients should be suspected of being infected even after H. pylori eradication if they have a high cutoff index in this test.

Abstract
BACKGROUND The vonoprazan (VPZ)-amoxicillin (AMO) dual therapy (VA) demonstrates a satisfactory eradication rate for Helicobacter pylori (H. pylori ). However, the optimal dosage of AMO in this regimen remains uncertain. The objective of this study is to investigate the efficacy of different doses of AMO in the VA regimen for first-line treatment of H. pylori infection. METHODS A total of 192 treatment-naive H. pylori -infected patients were randomly assigned to one of three groups: low-dose VA (LD-VA: VPZ 20 mg b.i.d + AMO 750 mg t.i.d), moderate-dose VA (MD-VA:VPZ 20 mg b.i.d + AMO 1000 mg t.i.d), and high-dose VA (HD-VA: VPZ 20 mg b.i.d + AMO 1250 mg t.i.d). All groups received 14 days of treatment. The study evaluated and compared the eradication rates, adverse events (AEs), and patient compliance among the three groups. RESULTS Eradication rates for LD-VA, MD-VA, and HD-VA were 76.6% (49/64), 79.7% (51/64), and 84.4% (54/64), respectively, as determined by intention-to-treat analysis; 90.6% (48/53), 94.3% (50/53), and 98.1% (53/54) according to per-protocol analysis; 89.1% (49/55), 94.4% (51/54), and 96.4% (54/56) with modified intention-to-treat analysis (all P > 0.05). Although not statistically significant, numerically higher eradication rates were observed with the higher dose AMO VA regimen. There were no statistically significant differences in the incidence of AEs and compliance among the three VA regimens. CONCLUSION Fourteen-day VA regimens with AMO doses exceeding 2 g/day demonstrated satisfactory eradication rates. HD-VA therapy is potentially the most effective regimen. Large-sample clinical trials are required to further validate these findings.

Assessment of the quality, diagnosis, and therapeutic recommendations of clinical practice guidelines on patients with Helicobacter pylori infection: A systematic review. GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:627-645. [PMID: 38307489 DOI: 10.1016/j.gastrohep.2024.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 01/14/2024] [Accepted: 01/22/2024] [Indexed: 02/04/2024]
Abstract
We conducted this study to systematically review and assess the current clinical practice guidelines (CPGs) related to the diagnosis and treatment of Helicobacter pylori (H. pylori) infection. The aim was to evaluate the quality of these included CPGs and provide clinicians with a convenient and comprehensive reference for updating their own CPGs. We searched four databases to identify eligible CPGs focusing on H. pylori diagnosis and treatment recommendations. The results were presented using evidence mappings. Quality and clinical applicability were assessed comprehensively using AGREE-II and AGREE-REX. Statistical tests, specifically Bonferroni tests, were employed to compare the quality between evidence-based guidelines and consensus. A total of 30 eligible CPGs were included, comprising 17 consensuses and 13 guidelines. The quality showed no statistical significance between consensuses and guidelines, mainly within the moderate to low range. Notably, recommendations across CPGs exhibited inconsistency. Nevertheless, concerning diagnosis, the urea breath test emerged as the most frequently recommended method for testing H. pylori. Regarding treatment, bismuth quadruple therapy stood out as the predominantly recommended eradication strategy, with high-dose dual therapy being a newly recommended option. Our findings suggest the need for specific organizations to update their CPGs on H. pylori or refer to recently published CPGs. Specifically, CPGs for pediatric cases require improvement and updating, while a notable absence of CPGs for the elderly was observed. Furthermore, there is a pressing need to improve the overall quality of CPGs related to H. pylori. Regarding recommendations, additional evidence is essential to elucidate the relationship between H. pylori infection and other diseases and refine test indications. Clinicians are encouraged to consider bismuth quadruple or high-dose dual therapy, incorporating locally sensitive antibiotics, as empirical radical therapy. .

Abstract
Helicobacter pylori infection is a major global health concern, and its management has witnessed a revolutionary shift with the emergence of antibiotic resistance. In this review, I explore the mechanisms of H. pylori antibiotic resistance and highlight the critical need for susceptibility-based eradication treatments. The increasing prevalence of antibiotic-resistant strains requires innovative approaches to combat this resilient pathogen. I also delve into the importance of mass screening as a preventive strategy for early detection and intervention, describing my experience in Bhutan. Additionally, I explore promising alternatives, such as vaccination. The aim of this review is to provide insight into the evolving landscape of H. pylori treatment and highlight the need for a paradigm shift in the approach to combating this persistent bacterial infection.

Abstract
PURPOSE OF REVIEW Potassium-competitive acid blockers (PCABs) represent a new class of compounds for the treatment of acid-related disorders. Recent FDA approval of the PCAB vonoprazan for erosive esophagitis has started an important new approach to acid-related disorders. RECENT FINDINGS Compared to conventional proton pump inhibitors (PPIs), PCABs provide more rapid, potent, and sustained suppression of gastric acid with faster and more durable symptom relief. Studies have demonstrated the efficacy of PCABs for erosive esophagitis, nonerosive reflux disease, and peptic ulcer disease including H. pylori. However, the PCAB vonoprazan was only approved in the US as part of combination therapy for eradication of H. pylori. Clinical trials have now demonstrated noninferiority of vonoprazan to lansoprazole for treatment of erosive esophagitis, particularly noting superiority of vonoprazan in patients with severe esophagitis resulting in FDA approval of vonoprazan for treatment of erosive esophagitis. Emerging data suggests a possible utility of vonoprazan for PPI-resistant gastroesophageal reflux disease (GERD) and on-demand therapy for nonerosive reflux disease. Vonoprazan is generally well tolerated but long-term safety data is not well established. SUMMARY The PCAB vonoprazan is a newly FDA approved treatment option for erosive esophagitis. Its possible role in PPI-resistant GERD and nonerosive reflux disease warrants further investigation.

Abstract
Background The efficacy and safety of potassium-competitive acid blockers (P-CABs) in the eradication of Helicobacter pylori (Hp) remains controversial when compared with proton pump inhibitors (PPIs). Objectives The current study set out to compare the differences in the eradication rate and adverse reactions between eradication regimens based on P-CAB or PPI drugs and the differences between the vonoprazan-based and the tegoprazan-based regimens to explore the efficacy and safety of different Hp eradication regimens. Data sources and methods Databases including PubMed, EMBASE, Cochrane Library, and WOS were searched from the inception of these databases up to July 2023, and eligible randomized controlled trials (RCTs) were included. The outcome measures were the eradication rate and the incidence of adverse reactions of different regimens in treating Hp. The results were estimated as relative risk (RR) and its 95% confidence interval (CI), and R 4.2.1 software was used to perform the network meta-analysis (NMA). Results A total of 20 studies were included in the analysis, involving 5815 patients with Hp. In terms of eradication rate, the 2-week vonoprazan-based triple regimen (V-Tri-2w) was the best, which was superior to the 2-week PPI-based quadruple regimen [P-Qua-2w, RR = 0.9, 95% CI: (0.85-0.95)] and the 1-week tegoprazan-based triple regimen [T-Tri-1w, RR = 0.79, 95% CI: (0.64-0.97)]; the 2-week tegoprazan-based quadruple regimen (T-Qua-2w) was superior to the 1-week PPI-based triple regimen [P-Tri-1w, RR = 0.82, 95% CI: (0.67-0.99)], and there was no difference between the remaining tegoprazan-based regimens and the PPI-based or vonoprazan-based regimens. In terms of the incidence of adverse reactions, the 2-week vonoprazan-based binary regimen (V-Bi-2w) was lower than that of the 2-week PPI-based quadruple regimen [P-Qua-2w, RR = 1.98, 95% CI: (1.57-2.52)]; there was no significant difference between 1 and 2 weeks for each regimen, such as the vonoprazan-based triple regimen [RR = 1.11, 95% CI: (0.82-1.52)]. Conclusion In the eradication treatment of Hp, the efficacy and safety of vonoprazan-based regimens are generally better than those of PPI-based regimens. Among them, the V-Tri-2w regimen has the highest eradication rate and may be the preferred choice for Hp eradication.

Helicobacter 2024; 29:e13106. [PMID: 38984746 DOI: 10.1111/hel.13106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 05/15/2024] [Accepted: 06/05/2024] [Indexed: 07/11/2024]
Abstract
Patients receiving hemodialysis (HD) often develop gastrointestinal diseases. Recently, although in general population, clinical guidelines for Helicobacter pylori have strongly recommended its eradication in patients to prevent gastric cancer, optimal eradication regimen and optimal dosage of drugs for patients receiving HD have not been established, due to possible incidence of adverse events. Some antimicrobial agents used in eradication therapy, particularly amoxicillin, can exacerbate renal dysfunction. Given the delayed pharmacokinetics of drugs in patients receiving HD compared with those in healthy individuals, drug regimen and dosage should be considered to minimize adverse effects. Although previous studies have investigated the benefits of eradication therapy for patients receiving HD, because most studies were small in terms of the number of enrolled patients, it is hard to show evidence. The numbers of eradication in HD patients have recently increased, and it is important to provide an optimal regimen. The consideration of eradication in patients undergoing HD with a reduction in the drug dose by 1/2-1/3 may prevent adverse events. Additionally, another important consideration is whether adverse events can be prevented while maintaining a similar eradication rate with reduced drug dosages. Recent meta-analysis findings indicate comparable eradication rates in patients receiving HD and healthy individuals, both with the same dosage regimen and at a reduced dosage regimen, with no significant differences (relative risk [RR] for successful eradication: 0.85 [95% confidence interval (CI): 0.48-1.50]). Unlike with the same dosage regimen (RR for adverse events: 3.15 [95% CI: 1.93-5.13]), the adverse events in the dosage reduction regimen were similar to those in healthy individuals (RR: 1.26 [95% CI: 0.23-6.99]). From a pharmacological perspective, the eradication regimen in patients receiving HD should consider the dosage (1/2-1/3 dosage), dosing number (bid), dosing timing of drugs (after HD), and susceptibility to antimicrobial agents.

Abstract
BACKGROUND This study aims to evaluate the efficacy and safety of vonoprazan-amoxicillin (VA), vonoprazan-amoxicillin-clarithromycin (VAC), vonoprazan-based bismuth-containing quadruple therapy (VBQT), and PPI-based triple (PAC) or quadruple therapy (PBQT) for H. pylori infection with the consideration of duration of therapy and amoxicillin dose (H: high; L: low). MATERIALS AND METHODS PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched for eligible randomized controlled trials (RCTs) up to December 15, 2023. The efficacy outcome was eradication rate, and safety outcomes included the rates of adverse events and treatment discontinuation. RESULTS Twenty-seven RCTs were included. The pooled eradication rates were 82.8% for VA, 89.1% for VAC, and 91.8% for VBQT, which increased with the higher amoxicillin frequency of administration and extended duration of therapy within each regimen. There were no significant differences in eradication rate when comparing 7-VA versus 7-VAC and 14-VA versus 14-VAC. VA was at least comparable to PAC. The eradication rate did not differ significantly between 10-H-VA or 14-H-VA versus 14-PBQT. 7-L-VAC demonstrated higher eradication rate versus 7-PAC and comparable rate to 14-PAC. 14-VBQT showed higher eradication rates versus 14-PBQT. The adverse events rate was 19.3% for VA, 30.6% for VAC, and 38.4% for VBQT. VA had similar risk of adverse events versus VAC and significantly fewer adverse events compared to PBQT. The treatment discontinuation rate did not differ significantly between treatments. CONCLUSIONS The eradication rate of VBQT was the highest at above 90% followed by VAC and VA. VA was as effective as VAC and superior to PPI-based therapies with favorable safety, highlighting the potential of VA therapy as a promising alternative to traditional PPI-based therapies. VPZ-based triple or quadruple therapies was more effective than PPI-based therapies. Further studies are needed to establish the optimal treatment regimen especially in the western countries.

Abstract
OBJECTIVE To compare the potential efficacy and safety of dual therapy and quadruple therapy with vonoprazan (VPZ) as well as the standard quadruple therapy of proton pump inhibitor (PPI) for the eradication of Helicobacter pylori (Hp) infection in Hainan province. METHODS A single-centre, non-blinded, non-inferiority randomized controlled trial was conducted at the outpatient department of gastroenterology at the Second Affiliated Hospital of Hainan Medical University from June 2022 to February 2023. 135 patients aged 18-75 years with Hp infection were enrolled and randomized into three different groups (group V1: VPZ 20 mg twice a day and amoxicillin 1.0 g three times a day for 14 days V2: vonoprazan 20 mg, amoxicillin capsules 1.0 g, furazolidone 0.1 g and bismuth potassiulm citrate 240 mg, twice daily for 14 days;; group V3: ilaprazole 5 mg, Amoxicillin 1.0 g, Furazolidone 100 mg, bismuth potassiulm citrate 240 mg, twice a day for 14 days). Four weeks after the end of treatment, Hp eradication was confirmed by rechecking 13C-urea breath test (UBT). RESULTS The eradication efficacy of V1 and V3 was non-inferior to that of V2, which is consistent with the results obtained from the Kruskal-Wallis H test. The eradication rate by intentional analysis was 84.4% (38/45, 95%CI 73.4%-95.5%, P>0.05) for all the three groups. If analyzed by per-protocol, the eradication rates were 88.4% (38/43, 95%CI 78.4%-98.4%), 92.7% (38/41, 95%CI 84.4%-101.0%),88.4% (38/43,95%CI 78.4%-98.4%) in groups V1, V2 and V3, respectively, which did not show a significant difference (P > 0.05). The incidence of adverse effects was significantly lower in VPZ dual therapy compared to the other two treatment regimens (P < 0.05). VPZ dual therapy or quadruple therapy was also relatively less costly than standard quadruple therapy. CONCLUSION VPZ dual therapy and quadruple therapy shows promise of not being worse than the standard quadruple therapy by a clinically relevant margin. More studies might be needed to definitively determine if the new therapy is equally effective or even superior.

Abstract
INTRODUCTION Clarithromycin resistance is a crucial factor in the eradication of Helicobacter pylori. This study aimed to evaluate the performance of MmaxSure™ H. pylori & ClaR Assay (MmaxSure™) in the diagnosis and detection of clarithromycin resistance in H. pylori. METHODS Subjects who underwent esophagogastroduodenoscopy between April 2020 and October 2022 were enrolled. The diagnostic performances of MmaxSure™ and dual priming oligonucleotide (DPO)-based multiplex polymerase chain reaction (PCR) were compared with the rapid urease test and culture. Secondary gene sequencing analysis was performed in discordant cases of PCR tests. RESULTS A total of 156 gastric biopsy samples were analyzed. In H. pylori detection, MmaxSure™ showed a 95.9% sensitivity (95% CI: 90.6-98.6), a 42.7% specificity (95% CI: 26.3-60.7), and a kappa value of 0.457. For the detection of A2143G mutation samples, MmaxSure™ showed a 91.2% sensitivity (95% CI: 76.3-98.1), a 93.4% specificity (95% CI: 87.5-97.1), and a kappa value of 0.804. There were a total of 10 discordant cases compared to gene sequencing in A2143G mutation detection for MmaxSure™. CONCLUSION In this study, MmaxSure™ showed comparable diagnostic performance to DPO-PCR in the detection of the H. pylori and A2143G mutation. Further research is needed to confirm the clinical effectiveness of the MmaxSure™ assay in H. pylori eradication.

Comparison of metronidazole versus clarithromycin in first-line vonoprazan-based triple therapy for Helicobacter pylori: A multicenter randomized trial in Japan. JGH Open 2024; 8:e13069. [PMID: 38650971 PMCID: PMC11034001 DOI: 10.1002/jgh3.13069] [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] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 03/11/2024] [Accepted: 04/04/2024] [Indexed: 04/25/2024]
Abstract
Background and Aim To date, no randomized trials have compared the efficacy of 7-day vonoprazan, amoxicillin, and metronidazole triple therapy (VAM) versus 7-day vonoprazan, amoxicillin, and clarithromycin triple therapy (VAC) as a first-line treatment for Helicobacter pylori eradication. This study was performed to compare the efficacy of VAM and VAC as first-line treatments. Methods This prospective multicenter randomized trial was performed in Japan and involved 124 H. pylori-positive patients without a history of eradication. Patients without antibiotic resistance testing of H. pylori were eligible. The patients were randomized to receive either VAC (vonoprazan 20 mg + amoxicillin 750 mg + clarithromycin 200 or 400 mg twice a day) or VAM (vonoprazan 20 mg + amoxicillin 750 mg + metronidazole 250 mg twice a day) for 7 days, with stratification by age and sex. Eradication success was evaluated using the 13C-urea breath test. We evaluated safety using patient questionnaires (UMIN000025773). Results The intention-to-treat and per-protocol eradication rates of VAM were 91.3% (95% confidence interval [CI], 82.0-96.7%) and 92.6% (95% CI, 83.7-97.6%), respectively, and those of VAC were 89.1% (95% CI, 77.8-95.9%) and 96.1% (95% CI, 86.5-99.5%), respectively. No significant difference was observed between VAM and VAC in either analysis (P = 0.76 and P = 0.70, respectively). Abdominal fullness was more frequent in patients who received VAM than VAC. Conclusions These findings suggest that VAM as a first-line treatment in Japan can be categorized as grade B (intention-to-treat cure rate of 90-95%) and have potential as a first-line national insurance -approved regimen.

Cho JH. Bismuth add-on improves the efficacy of 2-week tegoprazan-based triple therapy for first-line Helicobacter pylori eradication: a real-world evidence study. Expert Rev Anti Infect Ther 2024:1-7. [PMID: 38459869 DOI: 10.1080/14787210.2024.2329251] [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: 12/01/2023] [Accepted: 02/12/2024] [Indexed: 03/11/2024]
Abstract
BACKGROUND This study aimed to investigate the efficacy of bismuth added to a 2-week triple therapy consisting of tegoprazan (TPZ), amoxicillin, and clarithromycin for first-line Helicobacter pylori eradication. RESEARCH DESIGN AND METHODS We reviewed the retrospective data of patients who received a 2-week TPZ-based triple therapy with or without 300 mg bismuth twice daily. The primary endpoint was the H. pylori eradication rate of adding bismuth to the TPZ-based triple regimen (TAC-B group), compared to no bismuth added (TAC group). RESULTS In total, 306 and 256 patients were included in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively. The eradication success rates were significantly higher in the TAC-B group than in the TAC group (ITT, 82.9% vs. 71.8%, p = 0.029; PP, 95.8% vs. 87.5%, p = 0.027, respectively). The adherence rate to the eradication regimen was 100% in the TAC-B group and 97.0% in the TAC group. The adverse drug event rate in the TAC-B group was comparable to that in the TAC group (29.2% vs. 27.3%, p = 0.742). No use of bismuth was significantly associated with eradication failure (p = 0.038). CONCLUSIONS The bismuth add-on increased the first-line H. pylori eradication rate of 2-week TPZ-based triple therapy. CLINICAL TRIAL REGISTRATION www.clinicaltrials.gov identifier is NCT05453994.

Medicine (Baltimore) 2024; 103:e37476. [PMID: 38457567 PMCID: PMC10919513 DOI: 10.1097/md.0000000000037476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/07/2024] [Accepted: 02/12/2024] [Indexed: 03/10/2024] Open
Abstract
Vonoprazan, a novel acid suppressant and the first potassium-competitive acid blocker, has the potential to enhance the eradication rate of Helicobacter pylori due to its robust acid-suppressing capacity. This study aimed to compare the efficacy of vonoprazan-based dual therapy (vonoprazan-amoxicillin, VA) with vonoprazan-based bismuth quadruple therapy (VBQT) as a first-line treatment for H pylori infection. This retrospective single-center non-inferiority study was conducted in China. Treatment-naive H pylori-positive patients aged 18 to 80 received one of the 2 treatment regimens at our center. The VA group received vonoprazan 20 mg twice daily and amoxicillin 1000 mg 3 times daily for 14 days, whereas the VBQT group received vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and bismuth potassium citrate 220 mg twice daily for 14 days. The eradication rate was evaluated 4 to 6 weeks after treatment using the carbon-13/14 urea breath test. Propensity score matching was used to analyze eradication rates, adverse events (AEs), and patient compliance between the 2 groups. Initially, 501 patients were included, and after propensity score analysis, 156 patients were selected for the study. Intention-to-treat analysis showed eradication rates of 87.2% (95% CI, 79.8-94.6%) for the VA group and 79.5% (95% CI, 70.5-88.4%) for the VBQT group (P = .195). Per-protocol analysis demonstrated rates of 94.4% (95% CI, 89.2-99.7%) for the VA group and 96.8% (95% CI, 92.4-100%) for the VBQT group (P = .507). Non-inferiority was confirmed between the 2 groups, with P values < .025. The VA group showed a lower rate of AEs (10.3% vs 17.9%, P = .250) compared to the VBQT group. There were no significant differences in patient compliance between the 2 groups. In treatment-naive patients with H pylori infection, both the 14-day VA and VBQT regimens demonstrated comparable efficacy, with excellent eradication rates. Moreover, due to reduced antibiotic usage, lower rate of AEs, and lower costs, VA dual therapy should be prioritized.

Abstract
BACKGROUND Helicobacter pylori infection and its associated diseases represent a significant global health concern. Patients who cannot use amoxicillin pose a therapeutic challenge and necessitate alternative medications. Preliminary research indicates that cefuroxime demonstrates promising potential for eradicating H. pylori infection, and there is a lack of comprehensive review articles on the use of cefuroxime. MATERIALS AND METHODS This study conducts a thorough systematic literature review and synthesis. A comprehensive systematic search was conducted in PubMed, Web of Science, EMBASE, China National Knowledge Infrastructure, China Biology Medicine disc, and Wanfang Data up to January 13, 2024. The search strategy utilized the following keywords: (Cefuroxime) AND (Helicobacter pylori OR Helicobacter nemestrinae OR Campylobacter pylori OR Campylobacter pylori subsp. pylori OR Campylobacter pyloridis OR H. pylori OR Hp) for both English and Chinese language publications. Sixteen studies from five different countries or regions were included in final literature review. RESULTS Analysis results indicate that H. pylori is sensitive to cefuroxime, with resistance rates similar to amoxicillin being relatively low. Regimens containing cefuroxime have shown favorable eradication rates, which were comparable to those of the regimens containing amoxicillin. Regarding safety, the incidence of adverse reactions in cefuroxime-containing eradication regimens was comparable to that of amoxicillin-containing regimens or other bismuth quadruple regimens, with no significant increase in allergic reactions in penicillin-allergic patients. Regarding compliance, studies consistently report high compliance rates for regimens containing cefuroxime. CONCLUSION Cefuroxime can serve as an alternative to amoxicillin for the patients allergic to penicillin with satisfactory efficacies, safety, and compliance.

Abstract
BACKGROUND Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H. pylori infection status as a subanalysis of LCI-FIND trial. METHODS The patients were randomly allocated to receive white light imaging (WLI) first, followed by LCI (WLI group), or vice versa (LCI group), and the two groups were compared for the detection of tumors. Data from this trial were analyzed by the presence/absence of H. pylori infection and further analyzed by successful or unsuccessful eradication in the H. pylori infection group. RESULTS The 752 patients in the WLI group and 750 patients in the LCI group who had participated in the LCI-FIND trial were included. In the successful eradication group, more gastric lesions were detected by primary mode in the LCI group than in the WLI group, indicating that more lesions were missed by WLI. Fisher's exact probability test for the comparison of the WLI and LCI groups yielded a p-value of 0.0068, with missed gastric lesions being detected 0.136 times (95% confidence interval: 0.020-0.923), significantly less with LCI than with WLI. CONCLUSION The current study suggests that LCI should be used for gastric cancer screening, particularly in patients with successful H. pylori eradication.

Impact of mixed-infection rate of clarithromycin-susceptible and clarithromycin-resistant Helicobacter pylori strains on the success rate of clarithromycin-based eradication treatment. Helicobacter 2024; 29:e13062. [PMID: 38459683 DOI: 10.1111/hel.13062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 02/08/2024] [Accepted: 02/15/2024] [Indexed: 03/10/2024]
Abstract
BACKGROUND Clarithromycin (CAM) resistance is a major contributor to the failure to eradicate Helicobacter pylori (H. pylori). The mixed-infection ratio of CAM-susceptible and CAM-resistant H. pylori strains differs among individuals. Pyrosequencing analysis can be used to quantify gene mutations at position each 2142 and 2143 of the H. pylori 23S rRNA gene in intragastric fluid samples. Herein, we aimed to clarify the impact of the rate of mixed infection with CAM-susceptible and CAM-resistant H. pylori strains on the success rate of CAM-containing eradication therapy. MATERIALS AND METHODS Sixty-four H. pylori-positive participants who received CAM-based eradication therapy, also comprising vonoprazan and amoxicillin, were enrolled in this prospective cohort study. Biopsy and intragastric fluid samples were collected during esophagogastroduodenoscopy. H. pylori culture and CAM-susceptibility tests were performed on the biopsy samples, and real-time PCR and pyrosequencing analyses were performed on the intragastric fluid samples. The mutation rates and eradication success rates were compared. RESULTS The overall CAM-based eradication success rate was 84% (54/64): 62% (13/21) for CAM-resistant strains, and 95% (39/41) for CAM-sensitive strains. When the mutation rate of the 23S rRNA gene was 20% or lower for both positions (2142 and 2143), the eradication success rate was 90% or more. However, when the mutation rate was 20% or higher, the eradication success rate was lower (60%). CONCLUSIONS The mutation rate of the CAM-resistance gene was related to the success of eradication therapy, as determined via pyrosequencing analysis.

Abstract
BACKGROUND Vonoprazan, a novel acid suppressant, has recently emerged as a regimen for eradicating Helicobacter pylori. However, uncertainties exist about the effectiveness and safety of VPZ-based regimens compared with those of bismuth-based quadruple therapy in eradicating H. pylori. The present meta-analysis was performed to compare the effectiveness and safety of vonoprazan-based regimens with those of bismuth quadruple therapy in eradicating H. pylori. MATERIALS AND METHODS All randomized controlled trials and non-randomized controlled trials comparing the vonoprazan-based therapy with the bismuth quadruple therapy were included in this meta-analysis. Information was also extracted by two evaluators, and if heterogeneity existed, a random-effects model was used to calculate the combined relative ratio and 95% confidence interval; otherwise, a fixed-effects model was used. And subgroup analyses were performed to explore the sources of heterogeneity. RESULTS A total of 10 studies, comprising 2587 patients were included in the meta-analysis. The results showed that the combined eradication rate of patients treated with the vonoprazan-based regimen was significantly higher than that of patients treated with bismuth quadruple therapy, in both intention-to-treat and per-protocol analyses, and the differences were statistically significant. Among the intention-to-treat analyses results: (90.28% vs. 83.64% [odds ratio (OR) = 1.85, 95% confidence interval (CI) (1.27, 2.70), p = 0.001]); in the per-protocol analyses: (94.80% vs. 89.88%, [OR = 2.25, 95% CI (1.37, 3.69), p = 0.001]). The occurrence of adverse events was significantly lower in patients treated with vonoprazan-based regimens than in those treated with bismuth quadruple therapy, (14.50% vs. 25.89%, [OR = 0.49, 95% CI (0.32, 0.75), p = 0.001]). CONCLUSIONS For eradicating H. pylori, vonoprazan-based regimens are remarkably advantageous over bismuth quadruple therapy. Furthermore, vonoprazan-based regimens exhibit a lower rate of adverse events than bismuth quadruple therapy.

Abstract
BACKGROUND AND AIMS Helicobacter pylori (H. pylori) infections are widely treated with antibiotic regimens such as "Amoxicillin 1 gr 2 × 1 tablet, Clarithromycin 500 mg 2 × 1 tablet, and Lansoprazole 30 mg 2 × 1 tablet" for 14 days. We conducted a prospective observational study to explore whether this treatment protocol serves as a predisposing factor for the colonization of resistant gastrointestinal microflora, namely vancomycin-resistant enterococci (VRE), extended-spectrum beta-lactamase Enterobacterales (ESBL-E), and carbapenem-resistant Enterobacterales (CRE). MATERIALS AND METHODS Pre- and post-treatment stool samples from 75 patients diagnosed with H. pylori, without a prior treatment history, were cultured and evaluated based on the European Committee on Antimicrobial Susceptibility Testing (EUCAST) criteria. RESULTS Of the 75 evaluated patients, a pronounced surge in ESBL-E positivity was observed. Before initiating antibiotic treatment, 12 patients (16%) had ESBL-E-positive strains in their gastrointestinal tract. Notably, this number surged to 24 patients (32%) after the conclusion of the 14-day treatment regimen. The change was statistically significant, with a P value of less than 0.002, indicating a clear association between treatment for H. pylori and heightened ESBL-E colonization. Notably, VRE and CRE remained undetected in patients throughout the study, suggesting that the treatment regimen may specifically amplify the risk of ESBL-E colonization without affecting VRE and CRE prevalence. CONCLUSIONS As the inaugural report from Turkey on this issue, our study suggests that antibiotic regimens for H. pylori eradication contribute to the increased risk of ESBL-positive bacterial colonization in the gastrointestinal tract.

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.

Abstract
INTRODUCTION Helicobacter pylori eradication therapy may worsen gastroesophageal reflux disease that is a significant risk factor for Barrett's esophagus. However, the relationship between eradication therapy and Barrett's esophagus remains controversial. This study evaluated the impact of Helicobacter pylori eradication on the lengthening of Barrett's esophagus. MATERIALS AND METHODS We conducted a retrospective analysis of consecutive patients who successfully underwent Helicobacter pylori eradication between 2004 and 2017. Endoscopic images obtained before and after eradication therapy were compared for Barrett's esophagus length according to the Prague C&M criteria and the presence of reflux esophagitis based on the Los Angeles classification. RESULTS A total of 340 patients were analyzed (mean age: 66.9 ± 12.9 years) for a median follow-up of 55 months (interquartile range: 29.8-89.3). At the initial endoscopic assessment, 187 patients (55%) had a hiatal hernia, and all patients had gastric atrophy (C-0 to I: 2%, C-II to III: 47%, O-I to III: 51%). Reflux esophagitis was detected in 7 patients (2%) before eradication and in 21 patients (6%) afterward, which was a significant increase (p = 0.007). Barrett's esophagus was identified in 69 patients (20%) before eradication, with a median length of C0M1. Elongation after treatment was observed in only 2 patients (0.6%). We observed no significant increase in either the prevalence (p = 0.85) or the median length (p = 0.5) of Barrett's esophagus. CONCLUSIONS Only 0.6% of patients exhibited Barrett's esophagus lengthening after Helicobacter pylori eradication therapy, suggesting no significant impact of the treatment on the development or elongation of Barrett's esophagus.

Abstract
Helicobacter pylori is a pathogenic bacterium associated with various gastrointestinal diseases, including chronic gastritis, peptic ulcers, mucosa-associated lymphoid tissue lymphoma, and gastric cancer. The increasing rates of H. pylori antibiotic resistance and the emergence of multidrug-resistant strains pose significant challenges to its treatment. This comprehensive review explores the mechanisms underlying the resistance of H. pylori to commonly used antibiotics and the clinical implications of antibiotic resistance. Additionally, potential strategies for overcoming antibiotic resistance are discussed. These approaches aim to improve the treatment outcomes of H. pylori infections while minimizing the development of antibiotic resistance. The continuous evolution of treatment perspectives and ongoing research in this field are crucial for effectively combating this challenging infection.

Antimicrobial-resistant Helicobacter pylori in Japan: Report of nationwide surveillance for 2018-2020. Helicobacter 2024; 29:e13028. [PMID: 37823466 DOI: 10.1111/hel.13028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/22/2023] [Accepted: 09/27/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND Antimicrobial therapy is necessary to eradicate Helicobacter pylori infection. The emergence of antimicrobial-resistant bacteria poses a threat to continued treatment with antimicrobial agents. For those who prescribe antimicrobial therapy, it is necessary to constantly monitor the emergence of antimicrobial-resistant bacteria. METHOD H. pylori clinical isolates were collected in Japan from August 2018 to December 2020 for antimicrobial susceptibility testing. The agar dilution method was used for the determination of the minimum inhibitory concentration (MIC) of clarithromycin (CLR), amoxicillin (AMX), metronidazole (MNZ), and sitafloxacin (STX). RESULTS MICs for 938 H. pylori isolates were examined. The primary resistance rates of H. pylori clinical isolates for CLR, AMX, MNZ, and STX in Japan were 35.5%, 2.7%, 4.2%, and 27.6%, respectively. The primary resistance rates for CLR, AMX, and MNZ were significantly higher than those of the 2002-2005 isolates. The resistance rate for CLR was significantly higher in females (males: 30.7%, females: 41.5%, p < 0.001) and higher in the ≤29 years age group (54.8%) than in the other age groups, although there were no significant differences (p = 0.104). The MNZ resistance rate was significantly higher in the ≤29 years age group than in the other age groups (p = 0.004). The resistance rate for STX increased with age, but a significant difference was only seen between the 30-49 years age group and the ≥70 years age group (p < 0.001), and the resistance rate was significantly higher in strains isolated in the Kyushu region than in the other regions (p < 0.001). CONCLUSIONS The primary resistance rates for CLR, AMX, and MNZ of H. pylori clinical isolates in Japan were higher than those of the 2002-2005 isolates. Continuous surveillance is needed to monitor the trends in antimicrobial-resistant H. pylori.

Risk of map-like redness development after eradication therapy for Helicobacter pylori infection. Helicobacter 2024; 29:e13046. [PMID: 38984721 DOI: 10.1111/hel.13046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/01/2023] [Accepted: 12/11/2023] [Indexed: 07/11/2024]
Abstract
BACKGROUND Map-like redness is a newly identified endoscopic risk factor for gastric cancer in patients who received Helicobacter pylori eradication therapy. However, the incidence rate of map-like redness in patients who received eradication, and the risk factors for the development of map-like redness remain unclear. We hence aimed to investigate the incidence rate of map-like redness at 1-year post H. pylori eradication, and evaluated its associations with map-like redness and gastric cancer in relation with gastric condition. MATERIALS AND METHODS Endoscopic severity of gastritis and map-like redness were retrospectively evaluated according to the Kyoto Classification of Gastritis in patients who had undergone endoscopy before and after H. pylori eradication therapy. RESULTS The incidence rate of map-like redness for all 328 patients at a mean of 1.2 ± 0.6 years after eradication was 25.3% (95% confidence interval [CI]: 20.7%-30.4%). Patients who developed map-like redness were older, had more severe atrophy and intestinal metaplasia, a higher total score of the Kyoto Classification of Gastritis both before and after eradication, and a higher rate of gastric cancer history than patients who did not have map-like redness. On multivariate analysis, risk of map-like redness was increased in patients with intestinal metaplasia (odds ratio [OR]: 2.794, 95% CI: 1.155-6.757) and taking acid inhibitors (OR: 1.948, 95% CI: 1.070-3.547). Characteristics of H. pylori-positive patients with gastric cancer history were patients who were older (OR: 1.033, 95% CI: 1.001-1.066), taking acid inhibitors (OR: 4.456, 95% CI: 2.340-8.484), and with occurrence of map-like redness after eradication therapy (OR: 2.432, 95% CI: 1.264-4.679). CONCLUSIONS Map-like redness is observed in one fourth of patients at 1-year post eradication. Patients who developed map-like redness were found to have severe intestinal metaplasia and taking acid inhibitors, and hence such patients require increased attention at surveillance endoscopy.

Kakiuchi T. Important Recommendations Regarding the Test-and-Treat Strategy for Helicobacter pylori Infection in Children. INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2024; 61:469580231222649. [PMID: 38164932 PMCID: PMC10762879 DOI: 10.1177/00469580231222649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/07/2023] [Accepted: 12/07/2023] [Indexed: 01/03/2024]
Abstract
Helicobacter pylori is a commonly encountered pathogen in medical practice. It causes chronic gastritis in patients of different ages. Many published papers have provided different opinions on whether the test-and-treat strategy for H. pylori infection should be implemented in children. It is critical that the opinion in favor of this strategy was published in Europe, where ESPGHAN/NASPGHAN guidelines have not recommended the use of test-and-treat strategy for H. pylori in children. Herein, I propose my opinion regarding this debate using 4 main points. First, this strategy should be implemented in areas where its benefits outweigh the associated risks. Thus, if it is not tailored to the locality, the results of the test-and-treat strategy for H. pylori in children may be erroneous. Second, the association between H. pylori infection and other diseases such as asthma and other allergic diseases should not be factored in when considering the test-and-treat strategy. This is because these diseases are associated with H. pylori noninfection and not with its posteradication status. Third, there is evidence that H. pylori infection can significantly alter children's intestinal microbiota. Finally, gastroscopy should not be performed in all H. pylori-positive children, particularly if the drug susceptibility test is not available. In the near future, it will be possible to easily conduct drug susceptibility tests for H. pylori using fecal samples. I believe that this report may expand the test-and-treat strategy for children infected with asymptomatic H. pylori outside of Japan and prevent not only gastric cancer but also minor diseases such as iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, and failure to thrive. Pediatricians are responsible for keeping children healthy not only during childhood but also in adulthood. Thus, even if there are only a few H. pylori-related diseases and no severe cases in children, it is necessary to take early measures to prevent problems (eg, incidence of gastric cancer) in adulthood.

Abstract
Current global variations exist in Helicobacter pylori (H. pylori) eradication regimens. Triple therapy (TT), bismuth quadruple therapy (BQT), and high-dose dual therapy (HDDT) currently represent the predominant regimens. These regimens diverge in terms of treatment duration, the utilization of susceptibility testing, acid-inhibiting drug administration, and patient education. We conducted a comprehensive systematic literature review on these H. pylori treatment regimens. Our review aims to provide standardized treatment recommendations for H. pylori, reducing the risk of amalgamating findings from diverse eradication regimens. Recent research suggests that the optimal treatment duration for TT and BQT may be 14 and 10 days, respectively. Selecting the appropriate treatment duration for HDDT should rely on regional research evidence, and 14 days may be the optimal duration. The incorporation of susceptibility testing in TT is of paramount importance. In the case of BQT, the absence of susceptibility testing may be considered as an option, contingent upon cost and availability, and should be determined based on local antibiotic resistance patterns and the efficacy of empirical regimens. The type and dosage of acid-inhibiting drug would affect the efficacy of these regimens. Acid-inhibiting drugs should be selected and applied reasonably according to the population and therapies. Adequate patient education plays a pivotal role in the eradication of H. pylori. In regions with accessible local research evidence, the 10-day empirical BQT regimen may be considered a preferred choice for H. pylori eradication.

Int J Immunopathol Pharmacol 2024; 38:3946320241286866. [PMID: 39305222 PMCID: PMC11418347 DOI: 10.1177/03946320241286866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 07/21/2024] [Accepted: 08/23/2024] [Indexed: 09/25/2024] Open
Abstract
Background: A shorter treatment duration potentially offers the advantage of reducing adverse events (AEs) and enhancing patient compliance for Helicobacter pylori eradication. However, the difference in eradication rates between short-duration vonoprazan-based regimens and fourteen-day proton pump inhibitor (PPI)-based therapy remained unknown. Objective: This meta-analysis aimed to compare the efficacy and safety of ten-day vonoprazan-based regimens with fourteen-day conventional PPI-based therapy for H. pylori eradication. Methods: We performed a comprehensive literature search up to November 28, 2023, using PubMed. A random-effects model was applied to conduct a meta-analysis to determine the pooled Odds Ratio (OR) with 95% confidence intervals (CIs). Results: This meta-analysis included four randomized controlled clinical trials with 1560 patients. The H. pylori eradication rate of ten-day vonoprazan-based regimens was comparable to that of fourteen-day PPI-based therapy (88.7% vs 82.9%, OR 1.53, 95% CI [0.85-2.75], p = .16) in ITT analysis. The incidence of AEs in ten-day vonoprazan-based therapy was also similar to the control group (11.2% vs 17.6%, OR 0.66, 95% CI [0.33-1.31], p = .24). Conclusion: Current evidence suggests that the ten-day vonoprazan-based regimen is as effective as fourteen-day PPI-based therapy in eradicating H. pylori, with comparable AEs. However, additional research is required for confirmation.

Abstract
BACKGROUND Recent clinical trials have evaluated the efficacy of vonoprazan-amoxicillin (VA) dual therapy as the first-line treatment for Helicobacter pylori infection in different regions with inconsistent results reported. In this systematic review and meta-analysis, we aimed to evaluate the efficacy of VA dual therapy compared to the currently recommended therapy for eradicating H. pylori. MATERIALS AND METHODS A comprehensive search of the PubMed, Cochrane, and Embase databases was performed using the following search terms: ("Helicobacter" OR "H. pylori" OR "Hp") AND ("vonoprazan" OR "potassium-competitive acid blocker" OR "P-CAB") AND ("amoxicillin" OR "penicillin") AND ("dual"). The primary outcome was to evaluate the eradication rate according to intention-to-treat and per-protocol analysis. The secondary outcomes were adverse events and compliance. RESULTS A total of 15 studies involving 4, 568 patients were included. The pooled eradication rate of VA dual therapy was 85.0% and 90.0% by intention-to-treat and per-protocol analysis, respectively. The adverse events rate and compliance of VA dual therapy were 17.5% and 96%, respectively. The efficacy of VA dual therapy was superior to proton pump inhibitors-based triple therapy (82.0% vs. 71.4%, p < 0.01) but lower than vonoprazan-containing quadruple therapy (83.1% vs. 93.3%, p = 0.02). 7-day VA dual therapy showed lower eradication rates than 10-day (χ2 = 24.09, p < 0.01) and 14-day VA dual therapy (χ2 = 11.87, p < 0.01). The adverse events rate of VA dual therapy was lower than vonoprazan triple therapy (24.6% vs. 30.9%, p = 0.01) and bismuth-containing quadruple therapy (20.5% vs. 47.9%, p < 0.01). No significant difference of compliance was observed between VA dual therapy and each subgroup. CONCLUSION VA dual therapy, a novel regimen, showed high efficacy as the first-line treatment for H. pylori eradication, which should be optimized before application in different regions.

Wang XP, Shan RY, Li ZL, Kong XR, Hou RT, Wu HN, Chen CS. Metabolic improvements of novel microbial fermentation on black tea by Eurotium cristatum. Front Microbiol 2023; 14:1287802. [PMID: 38149271 PMCID: PMC10750952 DOI: 10.3389/fmicb.2023.1287802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 11/27/2023] [Indexed: 12/28/2023] Open
Abstract
Due to its traditional fermentation, there are obvious limits on the quality improvements in black tea. However, microbial fermentation can provide an abundance of metabolites and improve the flavor of tea. The "golden flower" fungi are widely used in the microbial fermentation of tea and has unique uses in healthcare. To further explore the improvements in black tea quality achieved via microbial fermentation, we used widely targeted metabolomics and metagenomics analyses to investigate the changes in and effects of metabolites and other microorganisms during the interaction between the "golden flower" fungi and black tea. Five key flavor metabolites were detected, the levels of catechin, epigallocatechin gallate, (-)-epicatechin gallate were decreased by different degrees after the inoculation of the "golden flower" fungus, whereas the levels of caffeine and (+)-gallocatechin increased. Botryosphaeriaceae, Botryosphaeriales, Dothideomycetes, Aspergillaceae, Trichocomaceae, and Lecanoromycetes play a positive role in the black tea fermentation process after inoculation with the "golden flower" fungi. D-Ribose can prevent hypoxia-induced apoptosis in cardiac cells, and it shows a strong correlation with Botryosphaeriaceae and Botryosphaeriales. The interaction between microorganisms and metabolites is manifested in tryptophan metabolism, starch and sucrose metabolism, and amino sugar and nucleotide sugar metabolism. In conclusion, the changes in metabolites observed during the fermentation of black tea by "golden flower" fungi are beneficial to human health. This conclusion extends the knowledge of the interaction between the "golden flower" fungi and black tea, and it provides important information for improving the quality of black tea.

A comparative systematic review and meta-analysis on the diagnostic accuracy of non-invasive tests for Helicobacter pylori detection in elderly patients. Front Med (Lausanne) 2023; 10:1323113. [PMID: 38143438 PMCID: PMC10748425 DOI: 10.3389/fmed.2023.1323113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 11/23/2023] [Indexed: 12/26/2023] Open
Abstract
Background Helicobacter pylori (H. pylori) infection, a type I carcinogen, affects approximately 50% of the global population, correlating with various gastric pathologies. Notably, diagnostic sensitivities of non-invasive methods, such as the stool antigen test (HpSA), Serology, and Urea Breath Test (UBT), have been suggested to be less effective in older age groups. This study systematically reviews and meta-analyzes the diagnostic accuracy of these tests within the elderly population. Methods A comprehensive literature search was performed across multiple databases, including PubMed, Medline, and Web of Science, up to July 2023. Data were pooled and analyzed using random-effects models. Sensitivity, specificity, and Diagnostic Odds Ratios (DOR) were computed for the tests. Heterogeneity and risk of bias were assessed. Results Eight studies involving diverse geographic locations and totaling between 46 and 1,441 participants per study were included. The pooled sensitivity and specificity for HpSA were 72.5 and 94.7%, for Serology 83.7 and 73.3%, and for UBT 96.4 and 88.3%, respectively. DOR for UBT, HpSA, and Serology were 94.5, 47.9, and 14.2, respectively. High levels of heterogeneity were observed across the studies. Conclusion UBT and HpSA proved effective for diagnosing H. pylori in those over 60, while serology showed lower specificity. Despite methodological variations in available studies, these non-invasive tests offer reliable alternatives, especially for older patients who recently undergone endoscopy or without an indication for it, warranting consideration by healthcare practitioners.

Effect of Helicobacter pylori eradication evaluated using magnifying endoscopy with narrow-band imaging in mixed-type early gastric Cancer. BMC Gastroenterol 2023; 23:425. [PMID: 38049718 PMCID: PMC10694948 DOI: 10.1186/s12876-023-03064-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 11/28/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND The effect of Helicobacter pylori (H.pylori) eradication therapy on mixed-histological-type gastric cancer remains unclear. This study aimed to clarify the effect of H. pylori eradication therapy on mixed-histological-type early gastric cancer using endoscopic and histological findings. METHODS This single-center, retrospective study included patients with mixed-histological-type gastric cancer who underwent endoscopic submucosal dissection at the Cancer Institute Hospital. We compared detailed magnifying endoscopy with narrow-band imaging findings between eradicated and non-eradicated groups of patients with differentiated-type- and undifferentiated-type-predominant cancers. Subsequently, we performed histological evaluations of the non-cancerous epithelium covering differentiated-type components. RESULTS A total of 124 patients with mixed-type early gastric cancer were enrolled (eradicated group: 62 differentiated-type-predominant cancer patients and 8 undifferentiated-type-predominant cancer patients; non-eradication group: 40 differentiated-type-predominant cancer patients and 14 undifferentiated-type-predominant cancer patients). Regarding differentiated-type-predominant cancer, differentiated-type findings were detected in all patients in eradicated and non-eradicated groups. The difference in the detection rate of undifferentiated-type findings between both groups was not significant in differentiated-type-predominant cancer patients. In differentiated-type-predominant cancers, the percentage of non-cancerous epithelium covering differentiated-type components was higher in the eradicated group than in the non-eradicated group (median: 60% vs. 40%, p < 0.001). CONCLUSIONS Although the pathological findings of differentiated-type-predominant cancer were affected by H. pylori eradication, eradication did not affect the diagnosis of differentiated-type-predominant early gastric cancer using magnifying endoscopy with narrow-band imaging. ME-NBI is useful for the early detection of D-MIX EGCs and diagnosis of histological types during endoscopy, regardless of whether H. pylori eradication therapy has been administered.

Abstract
BACKGROUND This study aimed to obtain an overview of clinical trials on Helicobacter pylori (H. pylori) eradication and analyze the global trends and hotspots in this field. METHODS We collected the data from clinical trials focused on H. pylori eradication in the primary clinical trial registries from 2000 to 2022 in the world. Then we analyzed the research trends and hotspots in H. pylori eradication regimens in different regions at different periods. RESULTS A total of 780 clinical trials were included, which were mainly conducted in Asia (682), followed by Europe (59), Africa (20), North America (16), South America (7), Oceania (2). The most active countries were China (343), Iran (140), South Korea (63), and Japan (73). "Bismuth-containing quadruple therapy (BQT)" was the most studied regimen (159, 20.38 %). Additionally, clinical trials focused on potassium-competitive acid blockers (P-CABs)-based therapy, probiotics, and high-dose dual therapy (HDDT) were constantly increasing. BQT received the most attention in China (26.53 %) and Iran (22.14 %), while it was tailored therapy in South Korea (23.29 %). P-CABs-based therapy was the main reseach hotspot in Japan (61.90 %). CONCLUSION How to eradicate H. pylori infection has been a heated research topic. BQT, P-CABs-based therapy, probiotics, and HDDT attracted the most attention in recent years.

Comparison of vonoprazan-based with rabeprazole-based dual therapy for treatment-naive patients of Helicobacter pylori infection: a prospective, multi-center, randomized controlled study. J Gastroenterol 2023; 58:1167-1177. [PMID: 37777987 DOI: 10.1007/s00535-023-02042-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 09/03/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND The application of vonoprazan significantly improved the eradication rate of Helicobacter pylori (H. pylori). This study aimed to compare efficacy and safety of the 10-day vonoprazan-amoxicillin (VA) and 14-day rabeprazole-amoxicillin (RA) dual therapy, and to provide a more efficient, safer, and convenient dual regimen for H. pylori infection. METHODS This was a prospective, open-label, multi-center, randomized controlled study of treatment-naive patients with H. pylori infection. The participants were randomly assigned to the 10-day VA group with vonoprazan 20 mg Bid plus amoxicillin 1 g Tid or the 14-day RA group with rabeprazole 10 mg Tid plus amoxicillin 1 g Tid. The effectiveness, the adverse events, and the patient compliance of the two groups were compared. RESULTS A total of 690 patients were enrolled. The eradication rates of 10-day VA and 14-day RA dual therapy were 89.3% and 84.9% in intention-to-treat (ITT) analysis (P = 0.088); 90.6% and 85.9% by modified intention-to-treat (mITT) analysis (P = 0.059); 91.4% and 86.6% by per-protocol (PP) analysis (P = 0.047). Non-inferiority was confirmed between the two groups (all P < 0.001). No discernible differences were observed in adverse effects and compliance between groups. Poor compliance reduced the eradication efficacy (P < 0.05). CONCLUSIONS The 10-day VA dual therapy was non-inferior to the 14-day RA dual therapy for H. pylori treatment-naive patients, which should be given priority in the first-line treatment. The application of vonoprazan reduced treatment course and antibiotic use. Patients' adherence was crucial for the success of eradication.

The influence of partial gastrectomy for gastric cancer on the spontaneous disappearance of Helicobacter pylori: A single-center prospective study. Cancer Rep (Hoboken) 2023; 6:e1903. [PMID: 37697944 PMCID: PMC10728519 DOI: 10.1002/cnr2.1903] [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: 04/23/2023] [Revised: 08/02/2023] [Accepted: 08/27/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND/AIMS Helicobacter pylori (HP) eradication is recommended after endoscopic treatment of early gastric cancer (EGC). Cases of spontaneous HP resolution after partial gastrectomy due to environmental changes have been reported; however, there is no evidence for the efficacy of HP eradication in suppressing carcinogenesis and also no reports on the natural history of HP after partial gastrectomy in gastric cancer (GC). To report the natural history of HP in patients with GC and HP infection after partial gastrectomy. METHODS AND RESULTS We prospectively studied the rate of spontaneous disappearance of HP after partial gastrectomy in patients with GC. From April 2016 to May 2020, 80 patients underwent partial gastrectomy, including 9 cases of proximal gastrectomy (PG), and 71 cases of distal gastrectomy (DG). The presence of HP was confirmed in the stool antigen test 1 year after operation, HP infection persisted in 46 patients (57.5%) and disappeared in 34 patients (42.5%). In univariate analysis, only proton pump inhibitor (PPI) use was a significant contributing factor for the spontaneous resolution of HP infection, especially in the DG group. However, there was no difference in the rates of HP disappearance between Billroth-I and Roux-en-Y reconstructions in the DG group. CONCLUSION The HP spontaneously disappeared in 42.5% of the GC patients within 1 year after partial gastrectomy. Further investigation in a larger cohort is needed to elucidate the underlying mechanisms.

Abstract
BACKGROUND Texture and color enhancement imaging (TXI) enhances the changes in endoscopic features caused by gastric neoplasms, such as redness/whiteness and elevation/depression. This study aimed to demonstrate the effectiveness of TXI in improving the visibility of gastric neoplasms compared with white light imaging (WLI) using conventional (CE) and newly developed endoscopes (NE). METHODS We recruited patients who were histologically diagnosed with gastric neoplasms; endoscopy was performed, and gastric neoplasms photographed using three imaging modalities, including WLI, TXI mode 1 (TXI-1) and TXI mode 2 (TXI-2). Two different endoscopes (CE and NE) were used for the same patients. Six endoscopists provided the visibility scale scores ranging from 1 (poor) to 4 (excellent) for gastric neoplasms. The primary outcome was the visibility scale scores based on each modality and endoscope. The secondary outcome was the identification of factors including H. pylori infection, atrophy, location, size, morphology, histological diagnosis and intestinal metaplasia that affect the differences in visibility scale scores between TXI-1/TXI-2 and WLI. RESULTS Fifty-two gastric neoplasms were analyzed. The mean visibility scale scores with the NE were 2.79 ± 1.07, 3.23 ± 0.96 and 3.14 ± 0.92 for WLI, TXI-1 and TXI-2, respectively. The mean visibility scales with the CE were 2.53 ± 1.10, 3.04 ± 1.05 and 2.96 ± 1.92 for WLI, TXI-1 and TXI-2, respectively. For both endoscopes, significant differences were observed in visibility scale scores between WLI and TXI-1 (p < 0.001) and between WLI and TXI-2 (p < 0.001). The visibility scale scores of NE were superior to those of CE in all modalities. In the secondary outcome, there was no factor affected the differences of visibility scale scores between TXI-1/TXI-2 and WLI. CONCLUSIONS This study demonstrated that TXI-1 and TXI-2 enhanced the visibility scale scores of gastric neoplasms compared with that of WLI. Moreover, newly developed endoscope has the potential to improve visibility compared to conventional endoscope.

Practice guidelines for the management of Helicobacter pylori infection: The Saudi H. pylori Working Group recommendations. Saudi J Gastroenterol 2023; 29:326-346.

Abstract
The eradication rates for Helicobacter pylori globally are decreasing with a dramatic increase in the prevalence of antibiotic resistant bacteria all over the world, including Saudi Arabia. There is no current consensus on the management of H. pylori in Saudi Arabia. The Saudi Gastroenterology Association developed these practice guidelines after reviewing the local and regional studies on the management of H. pylori. The aim was to establish recommendations to guide healthcare providers in managing H. pylori in Saudi Arabia. Experts in the areas of H. pylori management and microbiology were invited to write these guidelines. A literature search was performed, and all authors participated in writing and reviewing the guidelines. In addition, international guidelines and consensus reports were reviewed to bridge the gap in knowledge when local and regional data were unavailable. There is limited local data on treatment of H. pylori. The rate of clarithromycin and metronidazole resistance is high; therefore, standard triple therapy for 10-14 days is no longer recommended in the treatment of H. pylori unless antimicrobial susceptibility testing was performed. Based on the available data, bismuth quadruple therapy for 10-14 days is considered the best first-line and second-line therapy. Culture and antimicrobial susceptibility testing should be considered following two treatment failures. These recommendations are intended to provide the most relevant evidence-based guidelines for the management of H. pylori infection in Saudi Arabia. The working group recommends further studies to explore more therapeutic options to eradicate H. pylori.
