Yao QX, Li ZY, Kang HL, He X, Kang M. Effect of acacetin on inhibition of apoptosis in Helicobacter pylori-infected gastric epithelial cell line. World J Gastrointest Oncol 2024; 16:3624-3634. [DOI: 10.4251/wjgo.v16.i8.3624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/15/2024] [Accepted: 05/31/2024] [Indexed: 08/07/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection can cause extensive apoptosis of gastric epithelial cells, serving as a critical catalyst in the progression from chronic gastritis, gastrointestinal metaplasia, and atypical gastric hyperplasia to gastric carcinoma. Prompt eradication of H. pylori is paramount for ameliorating the pathophysiological conditions associated with chronic inflammation of the gastric mucosa and the primary prevention of gastric cancer. Acacetin, which has multifaceted pharmacological activities such as anti-cancer, anti-inflammatory, and antioxidative properties, has been extensively investigated across various domains. Nevertheless, the impact and underlying mechanisms of action of acacetin on H. pylori-infected gastric mucosal epithelial cells remain unclear.
AIM To explore the defensive effects of acacetin on apoptosis in H. pylori-infected GES-1 cells and to investigate the underlying mechanisms.
METHODS GES-1 cells were treated with H. pylori and acacetin in vitro. Cell viability was assessed using the CCK-8 assay, cell mortality rate via lactate dehydrogenase assay, alterations in cell migration and healing capacities through the wound healing assay, rates of apoptosis via flow cytometry and TUNEL staining, and expression levels of apoptosis-associated proteins through western blot analysis.
RESULTS H. pylori infection led to decreased GES-1 cell viability, increased cell mortality, suppressed cell migration, increased rate of apoptosis, increased expressions of Bax and cle-caspase3, and decreased Bcl-2 expression. Conversely, acacetin treatment enhanced cell viability, mitigated apoptosis induced by H. pylori infection, and modulated the expression of apoptosis-regulatory proteins by upregulating Bcl-2 and downregulating Bax and cleaved caspase-3.
CONCLUSION Acacetin significantly improved GES-1 cell viability and inhibited apoptosis in H. pylori-infected GES-1 cells, thereby exerting a protective effect on gastric mucosal epithelial cells.

[PMID: 38438197 DOI: 10.3399/bjgpo.2023.0252] [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: 12/28/2023] [Revised: 01/09/2024] [Accepted: 01/17/2024] [Indexed: 03/06/2024] Open
Abstract
BACKGROUND Owing to increasing antibiotic resistance, the worldwide efficacy of Helicobacter pylori (HP) eradication treatment has decreased. AIM To determine antimicrobial resistance of HP in primary care. DESIGN & SETTING Retrospective cohort study using real-world routine healthcare data from 80 general practices in the Netherlands. METHOD Patients with International Classification of Primary Care (ICPC) codes for gastric symptoms or Anatomical Therapeutic Chemical (ATC) codes for acid inhibition in the period 2010-2020 were selected. Main outcomes were antimicrobial resistance of HP, defined as the prescription of a second eradication treatment within 12 months, and clinical remission of gastric symptoms, defined as no usage of acid inhibition 1 year following eradication therapy. RESULTS We identified 138 455 patients with gastric symptoms and/or acid inhibition use (mean age 57 years [standard deviation 18.2 years], 43% male). A total of 5224 (4%) patients received an HP eradication treatment. A second treatment was prescribed to 416 (8%) of those patients. From these, 380 patients received amoxicillin-clarithromycin, 16 amoxicillin-metronidazole, and 11 clarithromycin-metronidazole as first regimen and were considered antimicrobial resistant. We observed a 0.8% increment per year of patients requiring a second eradication treatment (P = 0.003, 95% confidence interval = 0.33 to 1.22). After successful eradication, 2329/4808 (48%) patients used acid inhibition compared with 355/416 (85%) patients following treatment failure (P<0.001). CONCLUSION Antimicrobial treatment is not successful in almost one-tenth of HP infections in primary care after a first treatment containing clarithromycin and/or metronidazole. Although the treatment failure rate is not as high as reported in secondary care, the increasing trend is concerning and may require revision of the current guidelines.

Tetracycline Three Times Daily Versus Four Times Daily in Bismuth-Containing Quadruple Therapy as the First-Line Treatment of Helicobacter pylori Infection: A Multicenter, Noninferiority, Randomized Controlled Trial. Helicobacter 2024; 29:e13121. [PMID: 39097924 DOI: 10.1111/hel.13121] [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: 06/25/2024] [Revised: 07/14/2024] [Accepted: 07/23/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND Current guidelines recommend bismuth-containing quadruple therapy for patients newly diagnosed with Helicobacter pylori (H. pylori) infection. We aimed to compare the efficacy and safety of tetracycline administered three times daily versus four times daily in bismuth-containing quadruple therapy for first-line treatment of H. pylori infection. METHODS This multicenter, noninferiority, randomized controlled study, conducted in China, recruited treatment-naïve adults with H. pylori infection, randomized 1:1 into two treatment groups to receive either of the following bismuth-containing quadruple therapies: esomeprazole 20 mg twice-daily; bismuth 220 mg twice-daily; amoxicillin 1000 mg twice-daily; and tetracycline 500 mg three times daily (TET-T) versus 500 mg four times daily (TET-F). At least 6 weeks post-treatment, a 13C-urea breath test was performed to evaluate H. pylori eradication. RESULTS In total, 406 patients were randomly assigned to the two treatment groups. Intention-to-treat eradication rates were 91.63% (186/203; 95% confidence interval [CI] 87.82%-95.44%) versus 90.15% (183/203; 95% CI 86.05%-94.25%) (p = 0.0005) and per-protocol eradication rates were 95.34% (184/193; 95% CI 92.36%-98.31%) versus 95.72% (179/187; 95% CI 92.82%-98.62%) (p = 0.0002) for the TET-T and TET-F group, respectively. TET-T-treated patients had a lower incidence of adverse effects than TET-F-treated patients (21.61% vs. 31.63%, p = 0.024), with no significant differences in compliance to treatment between the groups. CONCLUSION As a first-line therapy for H. pylori infection, the eradication rate of the TET-T therapy was noninferior to that of the TET-F therapy while significantly reducing the incidence of adverse reactions. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT05431075.

Proteomic Characterization of a Lunasin-Enriched Soybean Extract Potentially Useful in the Treatment of Helicobacter pylori Infection. Nutrients 2024; 16:2056.

Abstract
Helicobacter pylori infection affects over 50% of the world's population and leads to chronic inflammation and gastric disorders, being the main pathogen correlated to gastric cancer development. Increasing antibiotic resistance levels are a major global concern and alternative treatments are needed. Soybean peptides and other compounds might be an alternative in the treatment to avoid, eradicate and/or control symptoms of H. pylori infection. This study aimed to characterize a lunasin-enriched soybean extract (LSE) using proteomics tools and to evaluate its antioxidant, anti-inflammatory and antibacterial properties against H. pylori infection. By LC-MS/MS analysis, 124 proteins were identified, with 2S albumin (lunasin and large-chain subunits) being the fourth most abundant protein (8.9%). Lunasin consists of 44 amino acid residues and an intramolecular disulfide bond. LSE at a low dose (0.0625 mg/mL) reduced ROS production in both H. pylori-infected and non-infected AGS gastric cells. This led to a significant reduction of 6.71% in the levels of pro-inflammatory interleukin (IL)-8. LSE also showed antibacterial activity against H. pylori, which can be attributed to other soybean proteins and phenolic compounds. Our findings suggest that LSE might be a promising alternative in the management of H. pylori infection and its associated symptoms.

Abstract
Helicobacter pylori (H. pylori) is a strict microaerophilic bacterial species that exists in the stomach, and H. pylori infection is one of the most common chronic bacterial infections affecting humans. Eradicating H. pylori is the preferred method for the long-term prevention of complications such as chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. However, first-line treatment with triple therapy and quadruple therapy has been unable to cope with increasing antibacterial resistance. To provide an updated review of H. pylori infections and antibacterial resistance, as well as related treatment options, we searched PubMed for articles published until March 2024. The key search terms were "H. pylori", "H. pylori infection", "H. pylori diseases", "H. pylori eradication", and "H. pylori antibacterial resistance." Despite the use of antimicrobial agents, the annual decline in the eradication rate of H. pylori continues. Emerging eradication therapies, such as the development of the new strong acid blocker vonoprazan, probiotic adjuvant therapy, and H. pylori vaccine therapy, are exciting. However, the effectiveness of these treatments needs to be further evaluated. It is worth mentioning that the idea of altering the oxygen environment in gastric juice for H. pylori to not be able to survive is a hot topic that should be considered in new eradication plans. Various strategies for eradicating H. pylori, including antibacterials, vaccines, probiotics, and biomaterials, are continuously evolving. A novel approach involving the alteration of the oxygen concentration within the growth environment of H. pylori has emerged as a promising eradication strategy.

Abstract
BACKGROUND The systematic use of susceptibility testing and tailored first-line treatment for Helicobacter pylori eradication has yet to be established. AIM To compare 14-day tailored PCR-guided triple therapy to 14-day non-Bismuth concomitant quadruple therapy for first-line Helicobacter pylori eradication. PATIENTS AND METHODS We performed a multicenter, parallel-group, randomized noninferiority controlled trial. Naive adult patients with Helicobacter pylori infection were treated with 14-day tailored PCR-guided triple therapy (esomeprazole 40 mg and amoxicillin 1000 mg b.d. plus clarithromycin 500 mg or levofloxacin 500 mg b.d. according to clarithromycin susceptibility) or 14-day non-Bismuth concomitant quadruple therapy (esomeprazole 40 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg b.d.). The primary endpoint was H. pylori eradication. RESULTS We screened 991 patients for eligibility and randomized 241 patients. The first-line eradication rate was 99.2% in the tailored PCR-guided group and 95.9% in the control group (ITT population; absolute difference of +3.30%, with a lower bound of CI at -0.68%). Both first-line therapies were well tolerated, with a formally significant difference in favor of the tailored PCR-guided group (61.4% vs. 41.2%, p = 0.003). Economic analyses revealed a lower cost of the tailored PCR-guided arm, with a 92% chance of being jointly more effective and less expensive than the control arm in the ITT population. CONCLUSION In a country with a high level of clarithromycin resistance, the results of our study demonstrated the noninferiority of 14-day tailored PCR-guided triple therapy as a first-line H. pylori eradication therapy compared to 14-day non-Bismuth quadruple therapy (ClinicalTrials.gov NCT02576236).

Abstract
Helicobacter pylori is the most common chronic bacterial infection worldwide and the most significant risk factor for gastric cancer, which remains a leading cause of cancer-related death globally. H pylori and gastric cancer continue to disproportionately impact racial and ethnic minority and immigrant groups in the United States. The approach to H pylori case-finding thus far has relied on opportunistic testing based on symptoms or high-risk indicators, such as racial or ethnic background and family history. However, this approach misses a substantial proportion of individuals infected with H pylori who remain at risk for gastric cancer because most infections remain clinically silent. Moreover, individuals with chronic H pylori infection are at risk for gastric preneoplastic lesions, which are also asymptomatic and only reliably diagnosed using endoscopy and biopsy. Thus, to make a significant impact in gastric cancer prevention, a systematic approach is needed to better identify individuals at highest risk of both H pylori infection and its complications, including gastric preneoplasia and cancer. The approach to H pylori eradication must also be optimized given sharply decreasing rates of successful eradication with commonly used therapies and increasing antimicrobial resistance. With growing acceptance that H pylori should be managed as an infectious disease and the increasing availability of susceptibility testing, we now have the momentum to abandon empirical therapies demonstrated to have inadequate eradication rates. Molecular-based susceptibility profiling facilitates selection of a personalized eradication regimen without necessitating an invasive procedure. An improved approach to H pylori eradication coupled with population-level programs for screening and treatment could be an effective and efficient strategy to prevent gastric cancer, especially in minority and potentially marginalized populations that bear the heaviest burden of H pylori infection and its complications.

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.

The global prevalence of Helicobacter pylori (H. pylori) infection remains high, indicating a persistent presence of this pathogenic bacterium capable of infecting humans. This review summarizes the population demographics, transmission routes, as well as conventional and novel therapeutic approaches for H. pylori infection. The prevalence of H. pylori infection exceeds 30% in numerous countries worldwide and can be transmitted through interpersonal and zoonotic routes. Cytotoxin-related gene A (CagA) and vacuolar cytotoxin A (VacA) are the main virulence factors of H. pylori, contributing to its steep global infection rate. Preventative measures should be taken from people's living habits and dietary factors to reduce H. pylori infection. Phytotherapy, probiotics therapies and some emerging therapies have emerged as alternative treatments for H. pylori infection, addressing the issue of elevated antibiotic resistance rates. Plant extracts primarily target urease activity and adhesion activity to treat H. pylori, while probiotics prevent H. pylori infection through both immune and non-immune pathways. In the future, the primary research focus will be on combining multiple treatment methods to effectively eradicate H. pylori infection.

Helicobacter 2024; 29:e13040. [PMID: 37983865 DOI: 10.1111/hel.13040] [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: 10/20/2023] [Revised: 11/08/2023] [Accepted: 11/09/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND AND OBJECTIVE Recently, vonoprazan-amoxicillin (VA) dual therapy has been reported as a promising approach for Helicobacter pylori (H. pylori) eradication. However, the effects of VA therapy versus bismuth-containing quadruple therapy (BQT) on H. pylori eradication remains unclear. The objective of this meta-analysis was to compare the effects of VA dual therapy with BQT for H. pylori eradication. METHODS A comprehensive search of the literature was conducted from the beginning to September 2023, utilizing PubMed, Embase, the Cochrane Library and Web of Science database. A random-effects model was used to perform a meta-analysis to determine the pooled relative risk (RR) with 95% confidence intervals (CIs). Moreover, trial sequential analysis (TSA) was conducted to evaluate the conclusiveness of the H. pylori eradication rate. RESULTS Six randomized controlled trials (RCTs) with 1233 patients were included. The VA therapy has similar eradication rate (ITT analysis: 87% vs. 85.7%, RR = 1.01, 95% CI: 0.93-1.09, p = 0.84; PP analysis: 92.5% vs. 93.2%, RR = 1.00, 95% CI: 0.94-1.06, p = 0.97) and compliance (RR = 1.01, 95% CI: 0.99-1.03, p = 0.32) compared to BQT. The VA therapy group had a significantly lower incidence of total adverse events than the BQT group (16.3% vs. 40.0%, RR = 0.45, 95% CI: 0.37-0.55, p < 0.00001). The TSA result showed that the effect was conclusive. CONCLUSIONS Current evidence indicated that VA therapy is just as successful as BQT in eliminating H. pylori, yet it has fewer adverse events and similar compliance.

Abstract
Helicobacter pylori is a potential underlying cause of many diseases. Although the Carbon 13 breath test is considered the gold standard for detection, it is high cost and low public accessibility in certain areas limit its widespread use. In this study, we sought to use machine learning and deep learning algorithm models to classify and diagnose H. pylori infection status. We used hyperspectral imaging system to gather gastric juice images and then retrieved spectral feature information between 400 and 1000 nm. Two different data processing methods were employed, resulting in the establishment of one-dimensional (1D) and two-dimensional (2D) datasets. In the binary classification task, the random forest model achieved a prediction accuracy of 83.27% when learning features from 1D data, with a specificity of 84.56% and a sensitivity of 92.31%. In the ternary classification task, the ResNet model learned from 2D data and achieved a classification accuracy of 91.48%.

Primary antibiotic resistance of Helicobacter pylori in the Asia-Pacific region between 1990 and 2022: an updated systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2024; 9:56-67. [PMID: 37972625 DOI: 10.1016/s2468-1253(23)00281-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 08/12/2023] [Accepted: 08/17/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND We previously showed rising primary antibiotic resistance of Helicobacter pylori during 1990-2015 in the Asia-Pacific region. However, whether primary antibiotic resistance continues to rise is unknown. Therefore, we aimed to assess the latest prevalence of H pylori antibiotic resistance in this region. METHODS We did an updated systematic review and meta-analysis of observational studies and randomised controlled trials published in PubMed, Embase, and Cochrane Library between Jan 1, 1990, and July 12, 2023. Studies investigating primary H pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline in individuals naive to eradication therapy in the Asia-Pacific region (as defined by the UN geoscheme) were eligible for inclusion. There were no language restrictions. Studies that focused on specific subpopulations (eg, children) were excluded. Using a standardised extraction form, two authors independently reviewed and extracted summary data from all eligible articles. The updated prevalence of antibiotic resistance was generated by meta-analysis under a random-effects model and subgroup analyses were done by countries and periods of study. Between-study variability was assessed by use of I2. The study is registered in PROSPERO, CRD42022339956. FINDINGS A total of 351 studies, including 175 new studies and 176 studies from our previous analysis, were included in this meta-analysis. The overall prevalence of primary antibiotic resistance of H pylori between 1990 and 2022 was 22% (95% CI 20-23; I2=96%) for clarithromycin, 52% (49-55; I2=99%) for metronidazole, 26% (24-29; I2=96%) for levofloxacin, 4% (3-5; I2=95%) for tetracycline, and 4% (3-5; I2=95%) for amoxicillin. Prevalence varied considerably between countries and across study periods. From 1990 to 2022, the prevalence of primary resistance increased for clarithromycin, metronidazole, and levofloxacin but remained stable for amoxicillin and tetracycline. The latest primary resistance prevalences were 30% (95% CI 28-33; I2=93%) for clarithromycin, 61% (55-66; I2=99%) for metronidazole, 35% (31-39; I2=95%) for levofloxacin, 4% (2-6; I2=96%) for tetracycline, and 6% (4-8; I2=96%) for amoxicillin in the Asia-Pacific region. INTERPRETATION Treatment guidelines should be adapted in response to the rising primary resistance of key antibiotics for H pylori eradication. A global policy to control and monitor the antibiotic resistance of H pylori is urgently needed.

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.

Abstract
Introduction. Helicobacter pylori is the leading cause of peptic ulcers and gastric cancer. The most common treatment regimens use combinations of two or three antibiotics and a proton pump inhibitor (PPI) to suppress stomach acid. The World Health Organization designated clarithromycin-resistant H. pylori as a high priority pathogen for drug development, due to increasing antibiotic resistance globally.Hypothesis/Gap Statement. There is no routine surveillance of H. pylori primary antimicrobial sensitivities in the UK, and published data are lacking.Aim. This study aimed to characterize antimicrobial sensitivities of isolates collected in Nottingham, UK, between 2001 and 2018.Methodology. Gastric biopsy samples were collected, with informed written consent and ethics approval, from 162 patients attending the Queen's Medical Centre in Nottingham for an upper GI tract endoscopy. Antibiotic sensitivity was assessed using E-Tests and a more cost-effective disc diffusion test.Results. The clarithromycin, amoxicillin and levofloxacin disc diffusion tests provided identical results to E-Tests on a subset of 30 isolates. Disparities were observed in the metronidazole test results, however. In total, 241 isolates from 162 patients were tested using at least one method. Of all isolates, 28 % were resistant to clarithromycin, 62 % to metronidazole and 3 % to amoxicillin, which are used in first-line therapies. For those antibiotics used in second- and third-line therapies, 4 % were resistant to levofloxacin and none of the isolates were resistant to tetracycline. Resistance to more than one antibiotic was found in 27 % of isolates. The frequency of patients with a clarithromycin-resistant strain increased dramatically over time: from 16 % between 2001 and 2005 to 40 % between 2011 and 2018 (P=0.011). For the same time periods, there was also an increase in those with a metronidazole-resistant strain (from 58 to 78 %; P=0.05). The frequencies of clarithromycin and metronidazole resistance were higher in isolates from patients who had previously received eradication therapy, compared to those who had not (40 % versus 77 %, and 80 % versus 92 %, respectively). Of 79 pairs of isolates from the antrum and corpus regions of the same patient's stomach, only six had differences in their antimicrobial susceptibility profiles.Conclusion. Although there was high and increasing resistance to clarithromycin and metronidazole, there was no resistance to tetracycline and the frequencies of amoxicillin and levofloxacin resistance were very low.

Abstract
Background Vonoprazan-amoxicillin (VA) dual therapy has recently been proposed to eradicate Helicobacter pylori (H. pylori) with controversial results. We, therefore, conducted a meta-analysis to assess the effect of this therapy for H. pylori eradication. Methods We searched PubMed, Embase, Cochrane Library, and Web of Science database from inception until November 2022, collecting randomized controlled trials (RCTs) comparing VA dual therapy with other regimens for H. pylori eradication. Pooled relative risks (RRs) were calculated using random effects model. Results Five RCTs were ultimately included. Compared with the vonoprazan-amoxicillin-clarithromycin (VAC) triple therapy, the eradication rate of VA dual therapy was lower in intention-to-treat (ITT) analysis (n = 3 RCTs, RR = 0.94, 95% CI: 0.88-0.99, P = 0.03), but there was no significant difference between them in the per-protocol (PP) analysis (RR = 0.96, 95% CI: 0.91-1.01, P = 0.11). For clarithromycin-resistant H. pylori strains, the eradication rate of VA dual therapy was significantly higher than that of the VAC triple therapy (n = 2 RCTs, RR = 1.20, 95% CI: 1.03-1.39, P = 0.02). Compared with the PPI-based triple therapy (PAC), VA dual therapy had a superior eradication rate (n = 2 RCTs, ITT analysis: RR = 1.13, 95% CI: 1.04-1.23, P = 0.003; PP analysis: pooled RR = 1.14, 95% CI: 1.06-1.22, P = 0.0004). Compared with VAC or PAC triple therapy, VA dual therapy has a similar incidence of total adverse events and compliance. Conclusions VA dual therapy had a similar effect compared to VAC triple therapy and was superior to PAC triple therapy. Future RCTs are needed to ascertain the optimal dosage and duration of vonoprazan and amoxicillin, and the effect of VA dual therapy compared with the mainstream regimens recommended by current guidelines.

Abstract
PURPOSE OF REVIEW The recognition that Helicobacter pylori should be considered and treated as an infectious disease has yet to fundamentally change diagnostic and treatment practices and has resulted in many controversies. RECENT FINDINGS We discuss the following controversies: whether the current 'per-patient' approach to H. pylori testing based on symptoms should be expanded to include achieving population-level H. pylori eradication, whether H. pylori should be approached as an infectious gastrointestinal disease similar to that of other infectious diseases of similar severity and outcome, whether treatment of H. pylori should be primarily empiric or based on antibiotic susceptibility and locally proven successful therapies as are other infectious diseases, whether it is necessary to obtain confirmation of treatment success in every patient treated for H. pylori , and whether potassium-competitive acid blockers should replace proton pump inhibitors in H. pylori therapy. SUMMARY Available guidelines and meta-analyses do not yet address H. pylori as an infectious disease. The diagnosis and management and treatment success of H. pylori infections trails behind that of other important infectious diseases. We provide new insights and propose changes in the traditional understanding required to modernize the management of H. pylori infections.

Abstract
OBJECTIVES To describe the pharmacology, efficacy, safety, and potential role of vonoprazan with amoxicillin or amoxicillin and clarithromycin for the treatment of Helicobacter pylori infection in adults. DATA SOURCES PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched using the terms: (vonoprazan OR voquezna) AND ("H. pylori" OR "Helicobacter pylori") AND amoxicillin with no date limitations up to November 3, 2022. STUDY SELECTION AND DATA EXTRACTION Studies assessing the efficacy and safety of vonoprazan with amoxicillin and/or clarithromycin were included and divided into 3 groups based on different comparisons between treatment regimens used in each group. DATA SYNTHESIS Ten clinical trials and 17 observational studies were included. Vonoprazan-based therapy demonstrated greater acid inhibition and similar or higher efficacy than proton-pump inhibitor (PPI)-based therapy in treatment-naïve patients and with clarithromycin-resistant infections. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE Proton-pump inhibitor-based therapies have not reached the desired successful eradication rate of 90% for H. pylori infection. Vonoprazan-based therapies being at least as effective as PPI-based therapies offer an alternative for patients with H. pylori infection. CONCLUSION Vonoprazan-based therapies were effective and well tolerated for the treatment of H. pylori infection in adults. These regimens provide an important alternative with prolonged acid inhibition, lower potential for CYP2C19 polymorphism, and at least comparable efficacy and safety versus PPI-based therapies in patients with H. pylori infections. Thus, vonoprazan-based therapy should be considered for certain patients, for example, those with failure to PPI-based treatments.

Abstract
Helicobacter pylori (H. pylori) is a bacterial pathogen in the stomach, causing gastritis, gastric ulcer, duodenal ulcer and even gastric cancer. The triple therapy containing one bismuth-containing compound or a proton-pump inhibitor with two antibiotics was the cornerstone of the treatment of H. pylori infections. However the drug resistance of Helicobacter pylori is more and more common, which leads to the continued decline in the radical cure rate. The purpose of this study was to investigate the mechanism of metronidazole resistance of H. pylori through transcriptomics and biochemical characterizations. In this study, a 128-time-higher metronidazole-resistant H. pylori strain compared to the sensitive strain was domesticated, and 374 significantly differential genes were identified by transcriptomic sequencing as compared to the metronidazole-sensitive strain. Through GO and KEGG enrichment analysis, antibiotic-resistance pathways were found to be mainly involved in redox, biofilm formation and ABC transportation, and the results were verified by qRT-PCR. The subsequent biochemical analysis found that the urease activity of the drug-resistant strain decreased, and whereas the capabilities of bacterial energy production, membrane production and diffusion ability increased. The work here will drop hints for the mechanisms of antibiotic-resistance of H. pylori and provide promising biomarkers for the further development of new-kind drugs to treat metronidazole-resistant H. pylori.

Abstract
BACKGROUND Antibiotic resistance of Helicobacter pylori (H. pylori) is increasing worldwide, with geographical variations, impacting the treatment outcomes. This study assessed the antibiotic resistance patterns of H. pylori in Vietnamese children. MATERIALS AND METHODS Symptomatic children undergoing gastroduodenoscopy at two tertiary Children's Hospitals in Ho Chi Minh City were recruited. Antral and corpus biopsies were obtained and cultured separately. Susceptibility to amoxicillin (AMO), clarithromycin (CLA), metronidazole (MET), levofloxacin (LEV), and tetracycline (TET) was determined using E-test. Polymerase chain reaction was performed on another antral biopsy to detect the urease gene, cytotoxin-associated gene A (cagA), vacuolating cytotoxin A (vacA) genotypes, and 23S rRNA mutations conferring CLA resistance. RESULTS Among 123 enrolled children, a high primary resistance rate was found for CLA (68.5%, 61/89), followed by LEV (55.1%), MET (31.5%), AMO (25.8%), and TET (1.1%). Secondary resistance rates were 82.1% (7/28), 71.4%, 53.6%, and 3.6% for CLA, LEV, MET, and TET, respectively. Multidrug resistance was frequent (67.7%), with common patterns including CLA + LEV (20.3%) and CLA + MTZ + LEV (15.2%). Heteroresistance was detected in eight children (6.5%). The A2143G mutation was detected in 97.5% (119/122) of children. 86.1% of children had positive cagA strains and 27.9% had multiple vacA genotypes. No factor was significantly associated with antibiotic resistance. CONCLUSIONS The alarming rate of antibiotic resistance for H. pylori, especially for CLA, with emerging multi- and hetero-resistant strains, pose a major treatment challenge that precludes CLA use as empirical therapy. Biopsies from both antrum and corpus can improve H. pylori culture, allowing tailored treatment based on antimicrobial susceptibility.

Abstract
Helicobacter pylori (H. pylori) is the most common chronic bacterial infection, affecting approximately half of the world's population. H. pylori is a Class I carcinogen according to the World Health Organization, and the International Agency for Research on Cancer (IARC) has linked it to 90% of stomach cancer cases worldwide. The overall pattern points to a yearly reduction in eradication rates of H. pylori with the likelihood of success further decreasing after each unsuccessful therapeutic effort. Antimicrobial resistance in Helicobacter pylori is a major public health concern and is a predominant cause attributed to eradication failure. As a result, determining H. pylori's antibiotic susceptibility prior to the administration of eradication regimens becomes increasingly critical. Detecting H. pylori and its antimicrobial resistance has traditionally been accomplished by time-consuming culture and phenotypic drug susceptibility testing. The resistance of H. pylori to different antibiotics is caused by various molecular mechanisms, and advances in sequencing technology have greatly facilitated the testing of antibiotic susceptibility to H. pylori. This review will summarize H. pylori antibiotic resistance patterns, mechanisms, and clinical implications. We will also review the pros and cons of current antibiotic susceptibility testing methods. Along with a comparison of tailored susceptibility-guided regimens and empirical therapy based on the latest evidence, an evidence-based approach to such situations will be explored.

Abstract
Helicobacter pylori (H. pylori) is a common bacterial infection linked to gastric malignancies. While H. pylori infection and gastric cancer rates are decreasing, antibiotic resistance varies greatly by community. Little is known about resistance rates among rural Indigenous populations in the United States. From 2018 to 2021, 396 endoscopy patients were recruited from a Northern Arizona clinic, where community H. pylori prevalence is near 60%. Gastric biopsy samples positive for H. pylori (n = 67) were sequenced for clarithromycin- and metronidazole-associated mutations, 23S ribosomal RNA (23S), and oxygen-insensitive NADPH nitroreductase (rdxA) regions. Medical record data were extracted for endoscopic findings and prior H. pylori history. Data analysis was restricted to individuals with no history of H. pylori infection. Of 49 individuals, representing 64 samples which amplified in the 23S region, a clarithromycin-associated mutation was present in 38.8%, with T2182C being the most common mutation at 90%. While the prevalence of metronidazole-resistance-associated mutations was higher at 93.9%, the mutations were more variable, with D95N being the most common followed by L62V. No statistically significant sex differences were observed for either antibiotic. Given the risk of treatment failure with antibiotic resistance, there is a need to consider resistance profile during treatment selection. The resistance rates in this population of American Indian patients undergoing endoscopy are similar to other high-risk populations. This is concerning given the high H. pylori prevalence and low rates of resistance testing in clinical settings. The mutations reported are associated with antibiotic resistance, but clinical resistance must be confirmed.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) affects nearly half of the world's populations with high incidence and prevalence rates in developing countries. Infection with H. pylori increases the risk of developing peptic ulcer disease and gastric cancer. This review provides a summary of the prevalence and microbiology of H. pylori with emphasis on the current diagnostic methods and clinical management strategies. CONTENT This review discusses current options and developments in H. pylori diagnosis with the challenges and advantages associated with both noninvasive and invasive methods. The advantages of molecular methods for the diagnosis of H. pylori infection and prediction of clarithromycin resistance directly from stool or tissue biopsies are discussed. In addition, we provide a brief review on the treatment for H. pylori indicated in patients with evidence of active infection with the organism's antimicrobial resistance patterns taken into consideration. SUMMARY Testing for H. pylori has largely centered around fecal antigen testing, urea breath testing, and immunohistochemical staining from tissue biopsies. Culture-based diagnostics followed by phenotypic antimicrobial susceptibility testing is the gold standard for detection of resistance patterns. Due to the fastidious nature of the organism, culture methods are time consuming and labor intensive. Rapid nucleic acid amplification tests for H. pylori identification from direct specimens and molecular determination of drug resistance markers are accurate alternatives for H. pylori diagnosis but are not widely adopted. H. pylori antimicrobial resistance rates are on the rise due to the widespread use of antibiotics. Antibiotic regimens including the quadruple therapy and non-clarithromycin triple therapies have a higher success rate, with newer vonoprazon-based regimens showing promising eradication rates.

The burden of stomach cancer mortality by county, race, and ethnicity in the USA, 2000-2019: a systematic analysis of health disparities. LANCET REGIONAL HEALTH. AMERICAS 2023; 24:100547.

Abstract
Background There are persistent disparities in stomach cancer mortality among racial-ethnic groups in the USA, but the extent to which these patterns vary geographically is not well understood. This analysis estimated age-standardised mortality for five racial-ethnic groups, in 3110 USA counties over 20 years, to describe spatial-temporal variations in stomach cancer mortality and disparities between racial-ethnic groups. Methods Redistribution methods for insufficient cause of death codes and validated small area estimation methods were applied to death registration data from the US National Vital Statistics System and population data from the US National Center for Health Statistics to estimate annual stomach cancer mortality rates. Estimates were stratified by county and racial-ethnic group (non-Latino and non-Hispanic [NL] American Indian or Alaska Native [AIAN], NL Asian or Pacific Islander [Asian], NL Black [Black], Latino or Hispanic [Latino], and NL White [White]) from 2000 to 2019. Estimates were corrected for misreporting of racial-ethnic group on death certificates using published misclassification ratios. We masked (ie, did not display) estimates for county and racial-ethnic group combinations with a mean annual population of less than 1000; thus, we report estimates for 3079 (of 3110) counties for the total population, and 474, 667, 1488, 1478, and 3051 counties for the AIAN, Asian, Black, Latino, and White populations, respectively. Findings Between 2000 and 2019, national age-standardised stomach cancer mortality was lowest among the White population in every year. Nationally, stomach cancer mortality declined for all racial-ethnic groups across this time period, with the most rapid declines occurring among the Asian (percent decline 48.3% [45.1-51.1]) and Black populations (42.6% [40.2-44.6]). Mortality among the other racial-ethnic groups declined more moderately, decreasing by 36.7% (35.3-38.1), 35.1% (32.2-37.7), and 31.6% (23.9-38.0) among the White, Latino, and AIAN populations, respectively. Similar patterns were observed at the county level, although with wide geographic variation. In 2019, a majority of counties had higher mortality rates among minoritised racial-ethnic populations compared to the White population: 81.1% (377 of 465 counties with unmasked estimates for both racial-ethnic groups) among the AIAN population, 88.2% (1295 of 1469) among the Latino population, 99.4% (663 of 667) among the Asian population, and 99.9% (1484 of 1486) among the Black population. However, the size of these disparities ranged widely across counties, with the largest range from 0.3 to 17.1 among the AIAN population. Interpretation Stomach cancer mortality has decreased substantially across populations and geographies in the USA. However, disparities in stomach cancer mortality among racial-ethnic groups are widespread and have persisted over the last two decades. Local-level data are crucial to understanding the scope of this unequal burden among minoritised groups in the USA.

Abstract
Despite the declining trend of Helicobacter pylori (H. pylori) prevalence around the globe, ongoing efforts are still needed to optimize current and future regimens in view of the increasing antibiotic resistance. The resistance of H. pylori to different antibiotics is caused by different molecular mechanisms, and advancements in sequencing technology have come a far way in broadening our understanding and in facilitating the testing of antibiotic susceptibility to H. pylori. In this literature review, we give an overview of the molecular mechanisms behind resistance, as well as discuss and compare different antibiotic susceptibility tests based on the latest research. We also discuss the principles of antibiotic stewardship and compare the performance of empirical therapies based on up-to-date resistance patterns and susceptibility-guided therapies in providing effective H. pylori treatment. Studies and clinical guidelines should ensure that the treatment being tested or recommended can reliably achieve a pre-agreed acceptable level of eradication rate and take into account the variations in antibiotic resistance across populations. Local, regional and international organizations must work together to establish routine antibiotic susceptibility surveillance programs and enforce antibiotic stewardship in the treatment of H. pylori, so that it can be managed in a sustainable and efficient manner.

Abstract
Helicobacter pylori (H. pylori) is the most common bacterial infection worldwide and one of the main etiological factors of chronic gastritis, peptic ulcer disease, and stomach neoplasms. The mass application of antibiotics without testing, especially during the last years of the pandemic of SARS-CoV-2, could lead to a dramatic increase in antibiotic resistance and reduced effectiveness of eradication regimens for H. pylori infection. The epidemiology of H. pylori resistance to antibiotics still has unclear mechanisms. Antibiotic policy should be intensified to optimize treatment, and regular monitoring of resistance of H. pylori in different geographical regions should be conducted. Individualized treatment according to susceptibility testing is strongly advisable, and the best treatment regimens should be selected. The mutations in the genes encoding the antibiotic target protein are significant risk factors for H. pylori resistance. Iatrogenic errors in diagnosis and prescribing treatment for the failure of H. pylori eradication are other important risk factors. The low level of awareness and compliance with the correct treatment influence the rate of H. pylori resistance. Epidemiological surveillance of antibiotic resistance and the adoption of new treatment strategies are needed. The discovery of an efficient vaccine against H. pylori could reduce the pressure of the world's growing antibiotic resistance.

Physiologically-based pharmacokinetic modelling to predict intragastric rifabutin concentrations in the treatment of Helicobacter pylori infection. Aliment Pharmacol Ther 2023; 58:159-167.

Abstract
BACKGROUND Sustained intragastric antibiotic exposure is important for Helicobacter pylori eradication, yet little is known about gastric pharmacology of commonly used H. pylori regimens. For rifabutin, differing intragastric concentrations based on dosing regimen may account for differences in reported eradication rates. AIM To compare intragastric rifabutin concentrations between low-dose rifabutin (50 mg three time daily; as in RHB-105) and generically dosed rifabutin 150 mg once daily, 150 mg twice daily, and 300 mg once daily using a validated Physiologically-based pharmacokinetic (PBPK) model. METHODS We obtained plasma pharmacokinetic data from the RHB-105 clinical development programs and used it to develop and validate a whole-body PBPK model using PK-SIM software. We modified the existing rifabutin model to include the impact of omeprazole on gastric pH and emptying time. Modelled intragastric rifabutin exposure was expressed as the time that each regimen maintained its concentration ≥MIC90 . RESULTS Rifabutin 50 mg three times daily achieved significantly longer times with intragastric concentration above MIC90 (22.3 ± 1.1 h) than 150 mg once daily (8.3 ± 1.7 h), 150 mg twice daily (16.3 ± 2.3 h), or 300 mg once daily (8.5 ± 1.9 h) while providing the lowest mean maximal plasma concentration and mean area under the plasma concentration-time curve of all regimens studied. CONCLUSIONS PBPK modelling showed rifabutin 50 mg three times daily had higher intragastric exposure times than 150 mg once daily or twice daily, or 300 mg once daily. This low-dose rifabutin regimen provides the highest potential for H. pylori eradication while minimising systemic rifabutin exposure.

Moss SF, Chey WD, Daniele P, Pelletier C, Jacob R, Tremblay G, Hubscher E, Leifke E, Malfertheiner P. Brief communication: global temporal trends in the efficacy of clarithromycin-based regimens for the treatment of Helicobacter pylori infection. Therap Adv Gastroenterol 2023; 16:17562848231167284. [PMID: 37388121 PMCID: PMC10302680 DOI: 10.1177/17562848231167284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 03/15/2023] [Indexed: 07/01/2023] Open
Abstract
Background Helicobacter pylori eradication rates achieved with clarithromycin-based triple therapies are declining due to antibiotic resistance, but data regarding temporal changes in efficacy with these eradication therapies are scarce. Objective To evaluate the efficacy of clarithromycin-based triple eradication regimens over time. Design A comprehensive literature review and time-trend analysis. Data sources and methods Bibliographies of recently published systematic literature reviews were searched and supplemented with a targeted literature review conducted using Medline and Embase databases and ProQuest from conception to May 2021. Studies reporting H. pylori eradication rates of clarithromycin-based triple therapies were included and temporal trends were estimated using a random-effects model. Results Eradication rates for triple therapies containing proton pump inhibitors (PPIs), clarithromycin, and amoxicillin showed a significant decline over the past 23 years (p = 0.0315). However, this decline was not significant when eradication rates achieved with vonoprazan-based triple therapy were included (p = 0.3910). Conclusion Vonoprazan-based triple therapy partially mitigated the decline in eradication rates seen with PPI-based triple therapy, likely due to more powerful acid suppression of vonoprazan.

Susceptibility-guided sequential strategy versus empirical therapy for Helicobacter pylori infection: study protocol for a randomised controlled trial. Trials 2023; 24:413. [PMID: 37337241 DOI: 10.1186/s13063-023-07457-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 06/13/2023] [Indexed: 06/21/2023] Open
Abstract
BACKGROUND New treatment strategies are required against infections caused by Helicobacter pylori, which grows increasingly resistant to antibiotics. Polymerase chain reaction-based methods for antibiotic susceptibility testing are available for detecting H. pylori-specific mutations that confer resistance to clarithromycin and levofloxacin. Several meta-analyses have compared eradication rates for susceptibility-guided versus empirical therapy for H. pylori treatment; however, all have significant limitations and high heterogeneity, and the results are contradictory. The main objective of this trial is to assess whether a sequential strategy based on molecular susceptibility testing-guided therapy for H. pylori has a better eradication rate than empirical therapy. METHODS This trial is designed as a prospective, randomised, open-label, active-controlled and single-centre study. Men and women who are H. pylori-positive, naïve to treatment, and aged 18-65 years will be recruited. A total of 500 participants will be randomised to receive either empirical therapy or a susceptibility-guided sequential strategy. Bismuth quadruple therapy will be the empirical first-line therapy, and in case of failure, high-dose dual (proton-pump inhibitor + amoxicillin) treatment will be the rescue therapy. For the susceptibility-guided sequential strategy, regimen selection will be based on H. pylori susceptibility to clarithromycin (first-line) and levofloxacin (rescue). A first-line treatment of clarithromycin triple therapy will be selected for clarithromycin-sensitive strains. For clarithromycin resistance, a high-dose dual therapy will be selected. During the rescue treatment, a levofloxacin quadruple regimen will be selected for levofloxacin-sensitive strains, and a furazolidone quadruple regimen will be selected for others. The primary outcome is the first-line eradication rate in both groups, and the overall (including first and rescue therapies) H. pylori eradication rate in both groups is one of the secondary outcomes. The eradication rates of H. pylori will be analysed by intention-to-treat analysis, modified intention-to-treat analysis, and per-protocol analysis. DISCUSSION This randomised controlled trial will provide objective and valid evidence about the value of polymerase chain reaction-based molecular methods for antibiotic susceptibility testing in guiding H. pylori eradication. TRIAL REGISTRATION Clinicaltrials.gov NCT05549115. Released on 18 September 2022. First posted on 22 September 2022. Enrolment of the first participant on 20 September 2022. The study is retrospectively registered.

Abstract
Resistance of Helicobacter pylori (H. pylori) to antibiotics has reached alarming levels worldwide, and the efficacy of the H. pylori eradication treatment has decreased dramatically because of antibiotic resistance. To gain a more comprehensive understanding of the development status, research hotspots, and future trends related to H. pylori antibiotic resistance, we conducted a thorough retrospective analysis via the bibliometrics method. We searched the Science Citation Index Expanded of the Web of Science Core Collection for all pertinent articles on H. pylori antibiotic resistance from 2013 to 2022. R-bibliometrix, CiteSpace, and VOSviewer tools were utilized to depict statistical evaluations in order to provide an unbiased presentation and forecasts in the field. We incorporated a total of 3,509 articles related to H. pylori antibiotic resistance. Publications were inconsistent prior to 2017, but steadily increased after 2017. China generated the most papers and the United States of America received the most citations and the highest H-index. Baylor College of Medicine was the most influential institution in this field, with the highest number of publications and citations, as well as the highest H-index. Helicobacter was the most productive journal, followed by the World Journal of Gastroenterology and Frontiers in Microbiology. The World Journal of Gastroenterology had the highest citation. Graham, David Y was the most productive and cited author. Clarithromycin resistance, prevalence, gastric cancer, quadruple therapy, sequential therapy, 23S rRNA, whole genome sequencing, bismuth, and probiotics appeared with a high frequency in the keywords. The top keywords with the highest citation bursts were vonoprazan, RdxA, biofilm formation, and fatty acid chain. Our research illustrated a multi-dimensional facet and a holistic knowledge structure for H. pylori antibiotic resistance research over the past decade, which can serve as a guide for the H. pylori research community to conduct in-depth investigations in the future.

Abstract
Chronic gastritis (CG) is a persistent inflammation of the gastric mucosa that can cause uncomfortable symptoms in patients. Traditional Chinese medicine (TCM) has been widely used to treat CG due to its precise efficacy, minimal side effects, and holistic approach. Clinical studies have confirmed the effectiveness of TCM in treating CG, although the mechanisms underlying this treatment have not yet been fully elucidated. In this review, we summarized the clinical research and mechanisms of TCM used to treat CG. Studies have shown that TCM mechanisms for CG treatment include H. pylori eradication, anti-inflammatory effects, immune modulation, regulation of gastric mucosal cell proliferation, apoptosis, and autophagy levels.

Abstract
According to the Maastricht VI consensus, the triple therapy (PPI + clarithromycin + amoxicillin) and bismuth-based quadruple therapy (PPI + bismuth + tetracycline + metronidazole) are considered and may be proscribed empirically as first-line regimens in the regions with low clarithromycin resistance rates (<15%). In the regions with high clarithromycin resistance rates (> 15%), as well as in the regions with unknown resistance to this antibacterial agent, it is recommended to use classical quadruple therapy with bismuth drugs as the main choice and quadruple therapy without bismuth drugs (“simultaneous” or “concomitant”) as an alternative. The second-line regimens of empiric choice (when antimicrobial susceptibility testing is not available) include fluoroquinolone-based quadruple therapy (PPI + levofloxacin + amoxicillin + bismuth) or fluoroquinolone-based triple therapy (PPI + levofloxacin + amoxicillin) and bismuth-based quadruple therapy. The Maastricht VI consensus regulates the use of rifabutin-based triple therapy (PPI + amoxicillin + rifabutin) as a “rescue” therapy, if the above ET schemes are ineffective and there is no possibility to conduct an antimicrobial susceptibility test. In its latest clinical guidelines, the Russian Gastroenterological Association (RGA) recommends with a view to achieving maximum treatment efficiency during classic triple ET and levelling the risk of further progression of clarithromycin resistance in Russia to take additional measures to increase its effectiveness (detailed instruction of a patient and control over strict adherence to the prescribed regimen, prolonging the course up to 14 days; prescribing PPI at increased dose twice a day; the latest generation PPIs (rabeprazole and esomeprazole); adding bismuth tripotassium dicitrate (240 mg 2 times a day) to the standard triple therapy; adding cytoprotector rebamipide (100 mg 3 times a day) to the standard triple therapy; adding a probiotic with proven efficacy to the standard triple therapy within controlled studies).

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

Abstract
Helicobacter pylori (H. pylori) can be eradicated immediately via local application of single-dose medicament on endoscopic examination. In our previous report, “the eradication rate of intraluminal therapy for H. pylori infection (ILTHPI) is 53.7% (51/95) using medicament containing amoxicillin, metronidazole, and clarithromycin”. We aimed to evaluate the efficacy and adverse events of medicament containing tetracycline, metronidazole, and bismuth and to improve the efficacy of stomach acid control before ILTHPI. After usage of dexlansoprazole (60 mg b.i.d.) or vonoprazan (20 mg q.d.) for 3 days before ILTHPI, 103 of 104 (99.1%) symptomatic H. pylori-infected treatment-naïve patients achieved levels of stomach pH ≥ 6. Patients were randomized to receive ILTHPI with medicaments containing tetracycline, metronidazole, and bismuth (Group A, n = 52) or amoxicillin, metronidazole, and clarithromycin (Group B, n = 52). The eradication rate of ILTHPI was similar between Group A (76.5%; 39/51) and Group B (84.6%, 44/52) (p = 0.427) and the adverse event was mild diarrhea (2.9%; 3/104). The eradication rate significantly increased from 53.7% (51/95) to 84.6% (44/52) after acid control (p = 0.0004) for Group B patients. The overall eradication rates of successful ILTHPI plus 7-day non-bismuth (Group A) or 7-day bismuth (Group B) oral quadruple therapy for ILTHPI failure patients were both excellent (96.1% for Group A and 98.1% for Group B).

Abstract
INTRODUCTION The economic and clinical implications of eradicating Helicobacter pylori ( H. pylori ) with vonoprazan-based and rifabutin-based regimens vs other existing prepackaged first-line treatment options in the United States are unknown. Therefore, we evaluated the cost-effectiveness of vonoprazan-based and rifabutin-based and other prepackaged regimens for the first-line treatment of H. pylori from the perspective of US healthcare payers. METHODS We used the state-transition Markov model to conduct a cost-effectiveness analysis of H. pylori eradication with clarithromycin triple, bismuth quadruple, vonoprazan dual, vonoprazan triple, and rifabutin triple regimens. In a cycle length of 2 months, the model estimated the expected costs (expressed in 2022 US$), expected quality-adjusted life-years (QALY), incremental cost-effectiveness ratios, and expected net monetary benefit over 20 years. In addition, we accounted for the present value of future costs and QALY by applying a 3% discounting rate. RESULTS In this study, rifabutin triple therapy had a lower expected cost but was more effective than clarithromycin triple, bismuth quadruple, and vonoprazan dual regimens; hence, it dominated them. Vonoprazan triple therapy had a higher expected cost (US$ 1,172 vs US$ 1,048) and expected QALY (14.262 vs 14.256) than rifabutin triple therapy, yielding an estimated incremental cost-effectiveness ratio of US$ 22,573/QALY. The study suggested that vonoprazan triple treatment had the highest expected net monetary benefit and was the most cost-effective at willingness-to-pay thresholds between US$50,000 and US$150,000 per QALY, followed by rifabutin triple therapy. DISCUSSION H. pylori infection eradication with vonoprazan triple therapy would provide the greatest net health and monetary benefit from the perspective of US healthcare payers.

Abstract
The eradication of Helicobacter pylori (H. pylori) infection remains challenging due to increasing bacterial resistance. Resistance rates to clarithromycin, metronidazole, and levofloxacin were higher than 30% in the USA, making current therapies less effective. Vonoprazan triple therapy (VAC) has demonstrated similar efficacy and safety profiles compared to PPI-based triple therapy (PPI). However, the eradication rate of vonoprazan dual therapy (VA) for H. pylori infection in comparison to VAC, and PPI was poorly established. Electronic databases were searched up to 6 October 2022, to identify studies examining the safety and efficacy of VA compared to VAC and PPI. Six studies were included. For empiric therapies among treatment naïve patients, VA, VAC, and PPI did not achieve high cure rates (>90%). The comparative efficacy ranking showed VAC was the most effective therapy, followed by VA, and PPI. The results were similar for clarithromycin-resistant infections. The comparative safety ranking showed VA ranked first, whereas PPI triple therapy was the least safe regimen. These findings should guide the selection of the most effective and safe treatment and conduct additional studies to determine the place of vonoprazan dual versus triple therapies in patients with H. pylori from various countries across the world.

Helicobacter pylori is a bacterial gastric pathogen that is the primary risk factor for carcinogenesis, associated with its induction of inflammation and DNA damage. Dicarbonyl electrophiles are generated from lipid peroxidation during the inflammatory response and form covalent adducts with amine-containing macromolecules. 2-hydroxybenzylamine (2-HOBA) is a natural compound derived from buckwheat seeds and acts as a potent scavenger of reactive aldehydes. Our goal was to investigate the effect of 2-HOBA on the pathogenesis of H. pylori infection. We used transgenic FVB/N insulin-gastrin (INS-GAS) mice as a model of gastric cancer. First, we found that 2-HOBA is bioavailable in the gastric tissues of these mice after supplementation in the drinking water. Moreover, 2-HOBA reduced the development of gastritis in H. pylori-infected INS-GAS mice without affecting the bacterial colonization level in the stomach. Further, we show that the development of gastric dysplasia and carcinoma was significantly reduced by 2-HOBA. Concomitantly, DNA damage were also inhibited by 2-HOBA treatment in H. pylori-infected mice. In parallel, DNA damage was inhibited by 2-HOBA in H. pylori-infected gastric epithelial cells in vitro. In conclusion, 2-HOBA, which has been shown to be safe in human clinical trials, represents a promising nutritional compound for the chemoprevention of the more severe effects of H. pylori infection.

High-dose dual therapy versus bismuth-containing quadruple therapy for Helicobacter pylori eradication: a systematic review and meta-analysis with trial sequential analysis. Therap Adv Gastroenterol 2023; 16:17562848221147756. [PMID: 36644129 PMCID: PMC9837272 DOI: 10.1177/17562848221147756] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 12/11/2022] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND AND OBJECTIVE Recently, a large number of trials on proton pump inhibitor-amoxicillin-containing high-dose dual therapy (HDDT) versus bismuth-containing quadruple therapy (BQT) for Helicobacter pylori (H. pylori) eradication have been published with controversial and inconsistent conclusions. The aim of this meta-analysis was to determine the effects of HDDT for H. pylori eradication compared to BQT. DESIGN A systematic review and meta-analysis was conducted. METHODS PubMed, Embase, and the Cochrane library database were searched to collect all randomized controlled trials (RCTs) assessing the effects of HDDT versus BQT to H. pylori eradication from inception to September 2022. Meta-analysis was conducted to estimate the pooled relative risk (RR) with 95% confidence intervals (CIs) using a random-effects model. Quality of evidence was appraised using Grading of Recommendations, Assessment, Development and Evaluation system. Trial sequential analysis (TSA) was performed to determine the reliability and conclusiveness. RESULTS A total of 14 RCTs with 5121 patients were included. The results of meta-analysis showed that there was no statistical significance in the eradication rate between HDDT and BQT (intention-to-treat analysis: 86.7% versus 85.1%, RR = 1.01, 95% CI: 0.98-1.04; per-protocol analysis: 89.9% versus 89.4%, RR = 1.01, 95% CI: 0.98-1.03; moderate-quality evidence). The incidence of total adverse effects in HDDT group was significantly lower than in BQT group (5.9% versus 34.1%, RR = 0.42, 95% CI: 0.34-0.50; low-quality evidence). No statistical significance was observed in compliance between HDDT and BQT (RR = 1.01, 95% CI, 1.00-1.03, p = 0.07; low-quality evidence). The TSA result for H. pylori eradication rate indicated that the effect was conclusive. CONCLUSIONS Evidence from our updated meta-analysis suggests that HDDT is as effective as BQT in eradicating H. pylori, with fewer adverse effects and similar compliance.

Clinical Implication of Drug Resistance for H. pylori Management. Antibiotics (Basel) 2022; 11:antibiotics11121684. [PMID: 36551341 PMCID: PMC9774604 DOI: 10.3390/antibiotics11121684] [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: 10/04/2022] [Revised: 11/08/2022] [Accepted: 11/17/2022] [Indexed: 11/24/2022] Open
Abstract
Rates of antimicrobial-resistance among H. pylori strains are increasing worldwide, resulting in declining eradication rates with current therapies, especially those containing clarithromycin or levofloxacin. To improve H. pylori management, a paradigm shift is needed, from the empiric approaches formerly employed, to regimen selection based upon knowledge of local and patient-level antimicrobial susceptibility data. We review the mechanisms of H. pylori antimicrobial resistance and the available worldwide pattern of resistance to key antimicrobials used in H. pylori therapy. The practicalities and challenges of measuring susceptibility in clinical practice is discussed, including not only conventional culture-based techniques but also novel sequencing-based methods performed on gastric tissue and stool samples. Though clinical trials of "tailored" (susceptibility-based) treatments have yet to show the clear superiority of tailored over empiric regimen selection, the ability to measure and modify treatment based upon antimicrobial susceptibility testing is likely to become more frequent in clinical practice and should lead to improved H. pylori management in the near future.

Abstract
Helicobacter pylori infection exhibits a wide disease spectrum ranging from asymptomatic gastritis, peptic ulcer disease, to gastric cancer. H. pylori can induce dysbiosis of gastric microbiota in the pathway of carcinogenesis and successful eradication can restore gastric homeostasis. Diagnostic testing and treatment for H. pylori infection is recommended in patients with active or past history of peptic ulcer, chronic dyspepsia, chronic non-steroidal anti-inflammatory drugs (NSAID) or aspirin use, precancerous gastric lesions, gastric cancer, mucosa-associated lymphoid tissue (MALT) lymphoma, family history of gastric cancer, family history of peptic ulcers, household family member having active H. pylori infection, iron deficiency anemia, idiopathic thrombocytopenic purpura, or vitamin B12 deficiency. Recommended first-line regimens for H. pylori eradication are classified according to clarithromycin resistance. In areas of high clarithromycin resistance (≥15%), we recommend 14-day concomitant therapy or 14-day bismuth quadruple therapy (BQT) as first-line regimen. In areas of low clarithromycin resistance (<15%), we recommend 14-day triple therapy or 14-day BQT as first-line treatment. Second-line regimens are 14-day levofloxacin triple therapy or 14-day BQT if BQT is not previously used. For patients with multiple treatment failure, antimicrobial susceptibility testing (AST) should be performed. If AST is not available, we recommend using antibiotics not previously used or for which resistance is unlikely, such as amoxicillin, tetracycline, bismuth, or furazolidone. High-dose potent proton pump inhibitor or vonoprazan is recommended to achieve adequate acid suppression. Probiotics can be used as an adjuvant treatment to reduce the side effects of antibiotics and enhance eradication rate.

Abstract
An analysis of the most important changes and provisions of the Maastricht VI consensus published in August 2022 is presented. 41 experts from 29 countries took part in the creation of the consensus. Recommendations have been developed in five areas: (1) indications for treatment and clinical associations of Helicobacter pylori (H. pylori) infection, (2) diagnosis, (3) treatment, (4) prevention of gastric cancer, (5) H. pylori and gastric microbiota -intestinal tract (GIT), taking into account the level of evidence and the strength of recommendations. Emphasis is placed on molecular testing, which is becoming an increasingly accessible research method in the world to identify both H. pylori itself and its sensitivity to antibiotics. The growing resistance of H. pylori strains to previously effective antibacterial agents requires a treatment strategy that implies the ability to determine the sensitivity of H. pylori to antibacterial agents both in the population and in a particular individual. The use of modern diagnostic tests expands the possibilities of individualization of therapy, since it allows determining not only the presence of H. pylori in the gastric mucosa, but also the sensitivity of the infection to antibacterial drugs. Along with individual approaches to treatment, the most effective empirical therapy regimens are given in case of impossibility to determine individual resistance to antibiotics. New data on the effectiveness and results of the use of primary and secondary preventive strategies for gastric cancer are presented. Given the important role of the entire microbiome of the gastrointestinal tract in the functioning of the body, the question of the interaction of H. pylori with other microorganisms is discussed. The critical issues of the near future are related to the global prevention of gastric cancer; the need to control antibiotic resistance, and the development of new methods of therapy and prevention of Helicobacter pylori infection.

Abstract
Background Helicobacter pylori (H. pylori) infects half of the human population globally. Eradication rates with triple or quadruple therapy have decreased owing to the increasing rate of antibiotic resistance. Jinghua Weikang capsule (JWC) is the first and most popular Chinese patent medicine approved by the state for the treatment of gastritis and peptic ulcers caused by H. pylori infection in China. Previous studies have found that JWC has a certain bactericidal effect on drug-resistant H. pylori and its major component, Chenopodium ambrosioides L. inhibits biofilm formation, but the mechanism remains unclear. This study focused on drug-resistant H. pylori and explored whether JWC could reverse drug resistance and its related mechanisms. Method The agar plate dilution method, E-test method, and killing kinetics assay were used to evaluate the bactericidal effect of JWC on antibiotic-resistant H. pylori and its effect on antibiotic resistance. Sanger sequencing was used to detect mutations in drug resistance genes. The crystal violet method, scanning electron microscopy, and confocal laser scanning microscopy were used to evaluate the effects of JWC on biofilms. qPCR was performed to evaluate the effect of JWC on the expression of efflux pump-related genes. qPCR and immunofluorescence were used to evaluate the effects of JWC on H. pylori adhesion. Results JWC showed considerable antibacterial activity against drug-resistant H. pylori strains, with minimum inhibitory concentration (MIC) values ranging from 64 to 1,024 μg/ml. The MIC of metronidazole (MTZ) against H. pylori 26,695–16R decreased from 64 to 6 μg/ml after treatment with 1/2 MIC of JWC. The resistance of H. pylori 26,695–16R to MTZ was reversed by JWC, and its effect was better than that of PaβN and CCCP. H. pylori 26,695–16R is a moderate biofilm-forming strain, and JWC (16–64 μg/ml) can inhibit the formation of biofilms in H. pylori 26,695–16R. JWC reduced the expression of HP0605-HP0607 (hefABC), HP0971-HP0969 (hefDEF), HP1327-HP1329 (hefGHI), and HP1489-HP1487. JWC reduced the adhesion of H. pylori to GES-1 cells and the expression of adhesives NapA, SabA, and BabA. Conclusion The reversal of MTZ resistance by JWC may be achieved through the adhesin/efflux pump-biofilm pathway.

Abstract
Helicobacter pylori (Hp) is a prevalent organism infecting almost half the global population. It is a significant concern, given its associated risk of gastric cancer, which is the third leading cause of cancer death globally. Infection can be asymptomatic or present with dyspeptic symptoms. It may also present with alarm symptoms in the case of progression to cancer. Diagnosis can be achieved non-invasively (breath tests, stool studies, or serology) or invasively (rapid urease test, biopsy, or culture). Treatment involves acid suppression and regimens containing several antibiotics and is guided by resistance rates. Eradication is essential, as it lowers the risk of complications and progression to cancer. Follow-up after eradication is similarly important, as the risk of cancer progression remains. There have been many recent advances in both diagnosis and treatment of Hp. In particular, biosensors may be effective diagnostic tools, and nanotechnology, vaccines, and potassium-competitive acid blockers may prove effective in enhancing eradication rates.
