Antibiotics (Basel) 2024; 13:136. [PMID: 38391522 PMCID: PMC10885881 DOI: 10.3390/antibiotics13020136] [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: 12/14/2023] [Revised: 01/18/2024] [Accepted: 01/19/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND non-bismuth sequential therapy (SEQ) was suggested as a first-line anti-Helicobacter pylori treatment alternative to standard triple therapy (STT). METHODS We conducted a systematic review with a meta-analysis of randomized controlled trials (RCTs) comparing the efficacy of 10-day SEQ vs. STT (of at least 7 days) using bibliographical searches up to July 2021, including treatment-naïve adult or children. The intention-to-treat (ITT) eradication rate and the risk difference (RD) were calculated. RESULTS Overall, 69 RCTs were evaluated, including 19,657 patients (9486 in SEQ; 10,171 in STT). Overall, SEQ was significantly more effective than STT (82% vs. 75%; RD 0.08; p < 0.001). The results were highly heterogeneous (I2 = 68%), and 38 studies did not demonstrate differences between therapies. Subgroup analyses suggested that patients with clarithromycin resistance only and all geographical areas but South America could benefit more from SEQ. Both therapies have evolved over the years, showing similar results when STT lasted 14 days; however, a tendency toward lower SEQ efficacy was noted from 2010 onwards. CONCLUSIONS Prior to 2010, SEQ was significantly more effective than STT, notably when 7-day STT was prescribed. A tendency toward lower differences between SEQ and STT has been noted, especially when using 10-day STT. None of the therapies achieved an optimal efficacy and therefore cannot be recommended as a valid first-line H. pylori treatment.

The nonadherence and risk factors of eradication failure by sequential therapy as first-line anti-Helicobacter pylori treatment in real-world clinical practice. Helicobacter 2024; 29:e13033. [PMID: 37950342 DOI: 10.1111/hel.13033] [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: 07/07/2023] [Revised: 09/25/2023] [Accepted: 10/23/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND The eradication rates of sequential therapy are high in clinical trials; however, the adherence for follow-up or the patient population in a real-world setting might be different from those in trails. This study investigates the effectiveness of sequential therapy in a real-world setting and the factors that lead to treatment failure. MATERIALS AND METHODS In this retrospective study, patients receiving sequential therapy as a first-line anti-Helicobacter pylori (H. pylori) treatment in a real-world setting were reviewed. The age adjusted Charlson Comorbidity Index (age-CCI) and baseline variety of medications were reviewed to determine factors correlated with nonadherence for post-treatment testing and H. pylori eradication failure. RESULTS A total of 1053 patients were reviewed. A total of 579 patients receiving sequential therapy were included in the analyses. Among them, 462 received post-treatment testing and were placed into the follow-up group. Thus, the post-treatment testing rate was 79.8%. Stroke was an independent factor of nonadherence for post-treatment testing. In the follow-up group, the eradication failure rate was 8.2%. Female sex (odds ratio [OR] 2.41 [95% CI 1.16-5.03], p = 0.02) and age-CCI ≥2 (OR 3.16 [1.05-9.48], p = 0.04) were independent factors of H. pylori eradication failure. The eradication failure rates were 14.4%, 7.8%, 7.1%, and 3.1% for the females with age-CCI ≥2, females with age-CCI <2, males with age-CCI ≥2, and males with age-CCI <2 subgroups, respectively (p = 0.027). CONCLUSIONS In a real-world setting, the adherence rate of post-treatment testing for sequential therapy as a first-line anti-H. pylori treatment was found to be suboptimal. Female sex and age-CCI ≥2 were independent factors of eradication failure.

Abstract
BACKGROUND With Helicobacter pylori's increasing antibiotic resistance, evidence of more effective treatments is lacking in China, where H. pylori prevalence is nearly 50%. Thus, we performed a network meta-analysis to compare therapeutic regimens. METHODS Data extracted from eligible randomized controlled trials from January 2000 to September 2021 were entered into a Bayesian hierarchical random-effects model to evaluate the efficacy and safety of H. pylori eradication regimens. RESULTS This study included 101 trials involving 21,745 patients. Vonoprazan-bismuth-containing quadruple therapy (VBQT) ranked the highest [surfaces under cumulative ranking curve (SUCRA), 83.64%], followed by high-dose amoxicillin dual therapy (HDDT) [SUCRA, 79.70%, odds ratio (OR)=1.31, 95% credible interval (CrI) (0.36, 4.72)] and proton pump inhibitor-based bismuth-containing quadruple therapy (BQT) [SUCRA, 63.59%, OR=1.59, 95% CrI (0.48, 5.24)]. HDDT [OR=2.47, 95% CrI (1.51, 4.06)], BQT [OR=2.04, 95% CrI (1.69, 2.47)], concomitant quadruple nonbismuth therapy (CT) [OR=1.93, 95% CrI (1.19, 3.15)], and sequential therapy (ST) [OR=1.86, 95% CrI (1.50, 2.32)] had higher eradication rates than standard triple therapy (TT). ST (SUCRA, 82.52%) and VBQT (SUCRA, 83.89%) had the highest eradication rate before and after 2010 in the effectiveness ranking, respectively. Furthermore, the H. pylori eradication rate of patients receiving 14-day BQT treatment was higher than that of 10-day BQT regimen [OR=2.55, 95% CI (1.84, 3.53)] and 7-day BQT regimen [OR=3.64, 95% CI (2.64, 5.01)]. CONCLUSIONS The TT regimen was not an optimal choice in China for H. pylori eradication; VBQT, HDDT, and BQT showed better efficacy. After 2010, there is a trend toward significance that VBQT provided a higher H. pylori eradication rate in China, but with only 1 randomized controlled trial. Thus, more supportive real-world data are needed to confirm its effectiveness.

Abstract
BACKGROUND AND AIM There is regional variation in the eradication rates of Helicobacter pylori (H. pylori) regimens depending on the local antibiotic resistance patterns. The aim of this study was to compare the efficacies of triple, quadruple and sequential antibiotic therapy in eradicating H. pylori infection. METHODS A total of 296 H. pylori-positive patients were randomized to receive one of the three regimens (triple, quadruple or sequential antibiotic therapy) and eradication rate was assessed by H. pylori stool antigen test. RESULTS The eradication rates of standard triple therapy, sequential therapy and quadruple therapy were 93%, 92.9% and 96.4%, respectively (p = 0.57). CONCLUSION Fourteen days of standard triple therapy, 14 days of bismuth-based quadruple therapy and 10 days of sequential therapy are equally efficacious in eradicating H. pylori and all regimens have optimum H. pylori eradication rates.

Front Pharmacol 2023; 14:1096103. [PMID: 36817141 PMCID: PMC9931190 DOI: 10.3389/fphar.2023.1096103] [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: 11/11/2022] [Accepted: 01/23/2023] [Indexed: 02/04/2023] Open
Abstract
Background: Currently, the management of Helicobacter pylori (H. pylori) infection in elderly patients is controversial. We investigated whether high-dose dual therapy would serve as the first-line therapy in elderly patients. Methods: This was a single-center, randomized study of 150 elderly patients with H. pylori infection who were randomly assigned to 14-day therapy with pantoprazole 40 mg 3 times daily and either amoxicillin 1,000 mg 3 times daily or amoxicillin 1,000 mg twice daily, clarithromycin 500 mg twice daily and bismuth 220 mg twice daily. H. pylori eradication was evaluated by a 13C-urea breath test 4 weeks after the completion of treatment. Results: Successful eradication was achieved in 89.3% of the high-dose dual therapy (HT) group in the intention-to-treat (ITT) analysis, 91.7% in the modified intention-to-treat (mITT) analysis, and 93.0% for per-protocol (PP) analysis which was similar to the bismuth-containing quadruple therapy (BQT) group (86.6%, 87.8%, and 90.3%, respectively). There were no significant difference between the HT group and the BQT group in the ITT analysis (p = 0.484), mITT analysis (p = 0.458), or PP analysis (p = 0.403). HT was associated with fewer side effects (10.6% of patients) than BQT (26.6%) (p = 0.026). Conclusion: In this trial, we found that 14-day HT had a similar eradication rate to BQT but fewer side effects, which may be better for elderly patients.

World J Clin Cases 2022; 10:12959-12970. [PMID: 36569016 PMCID: PMC9782940 DOI: 10.12998/wjcc.v10.i35.12959] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/08/2022] [Accepted: 11/30/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND As a first-line treatment regimen for Helicobacter pylori (H. pylori) infection, antibiotic therapy is widely used worldwide. However, the question of increasing antibiotic resistance must be considered. Given this issue, we need to find ways to reduce drug resistance. This study examined all currently available first-line regimens and compared them with standard triple treatment through a network meta-analysis of randomized controlled trials (RCTs).
AIM To compare first-line treatment regimens for eradication of antibiotic-resistant H. pylori strains.
METHODS To compare the effectiveness of the first-line regimens for treating H. pylori infection, a Bayesian network meta-analysis was applied to process data extracted from RCTs. The plausible ranking for each regimen was assessed by the surface under the cumulative ranking curve (SUCRA). In addition, we conducted a relevant search by reference citation analysis.
RESULTS Twenty-five RCTs involving 12029 participants [including 1602 infected with clarithromycin (CAM)-resistant strains and 1716 infected with metronidazole (MNZ)-resistant strains] were included, in which a total of seven regimens were used for H. pylori eradication. The results showed that dual therapy containing a high-dose proton pump inhibitor (HDDT) [odds ratio (OR): 4.20, 95% confidence interval (CI): 2.29-8.13] was superior to other therapies for all patients, including those with CAM/MNZ-resistant H. pylori infection. In the comparative effectiveness ranking, for CAM-resistant H. pylori, HDDT (OR: 96.80, 95%CI: 22.46-521.9) had the best results, whereas standard triple therapy ranked last (SUCRA: 98.7% vs 0.3%). In the subgroup of high cure rates (≥ 90%), HDDT was also generally better than other therapies.
CONCLUSION For the eradication of CAM- and MNZ-resistant H. pylori strains, HDDT exhibited considerable advantages. The studies of CAM-resistant H. pylori were based on small samples due to a lack of antibiotic sensitivity tests in many RCTs, but the results showed that all patients, including those with CAM-resistant H. pylori infection, had a concordant trend. Overall, HDDT may be a reference for RCTs and other studies of H. pylori eradication.

REAP-HP survey 2020: Comparing the real-world practice and expectation in Helicobacter pylori eradication of the Taiwanese gastroenterologists in 2015 and 2020. Helicobacter 2022; 27:e12931. [PMID: 36161426 DOI: 10.1111/hel.12931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Revised: 08/25/2022] [Accepted: 08/30/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND REAP-HP study (Real-world practice and Expectation of Asia-Pacific physicians and patients in Helicobacter Pylori eradication) was the pioneer study investigating the expectation and preference of physicians across Asia-Pacific in H. pylori eradication in 2015. This study is the first follow-up study of REAP-HP in Taiwan. AIMS (1) To investigate the preference in regimens for the first-line anti-H. pylori therapy of Taiwanese gastroenterologist in 2020, (2) To survey the factor that cause the most concern when prescribing anti-H. pylori regimens in clinical practice, and (3) to compare REAP-HP survey data in 2020 and those surveyed in 2015 regarding the abovementioned end-points. METHODS A questionnaire for H. pylori eradication survey of physicians was distributed to the gastroenterologists who attended the Taiwan Digestive Disease Week 2020. Data of most commonly used first-line anti-H. pylori regimens and concerned factors when prescribing anti-H. pylori regimens between 2015 and 2020 were compared. RESULTS A total of 258 physicians from different districts of Taiwan participated in the REAP-HP Survey in 2020. The top three most commonly used anti-H. pylori regimens in Taiwan in 2020 were 14-day standard triple therapy (36.8%; 95% confidence interval [CI]: 30.9%-42.7%), 7-day standard triple therapy (17.8%; 95% CI: 13.1%-22.5%) and 14-day reverse hybrid therapy (14.7%; 95% CI: 10.4%-19.0%) respectively. The top two factors that cause the most concern during prescribing anti-H. pylori therapy were eradication rate (82.3%; 95% CI: 77.6%-87.0%) and side effect (10.4%; 95% CI: 6.7%-15.1%). In 2015, the top three most commonly used regimens in Taiwan were 7-day standard triple therapy (62%; 95% CI: 56.2%-67.8%), 14-day standard triple therapy (21%; 95% CI: 16.1%-25.9%) and 10-day sequential therapy (7%; 95% CI: 4%-10%). A remarkable difference of the most commonly used anti-H. pylori regimens between 2015 and 2020 existed (p < .001). The top two factors that cause the most concern during prescribing anti-H. pylori therapy in 2015 were eradication rate (84.1%) and side effect (7.0%). There were no differences in the factors that cause the most concern during prescribing anti-H. pylori regimens between 2015 and 2020. CONCLUSION 14-day standard triple therapy has replaced 7-day standard triple therapy as the most commonly used first-line anti-H. pylori therapy among Taiwanese gastroenterologists in 2020. 14-day reverse hybrid therapy is on rise to the third place as the most commonly used anti-H. pylori regimen in Taiwan.

Shih CA, Shie CB, Hsu PI. Update on the first-line treatment of Helicobacter pylori infection in areas with high and low clarithromycin resistances. Therap Adv Gastroenterol 2022; 15:17562848221138168. [PMID: 36458050 PMCID: PMC9706057 DOI: 10.1177/17562848221138168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 10/24/2022] [Indexed: 11/23/2022] Open
Abstract
Current international consensuses on Helicobacter pylori eradication therapy recommend that only regimens that reliably produce eradication rates of ⩾90% should be used for empirical treatment. The Real-world Practice & Expectation of Asia-Pacific Physicians and Patients in Helicobacter Pylori Eradication Survey also showed that the accepted minimal eradication rate in H. pylori-infected patients was 91%. According to efficacy prediction model, the per-protocol eradication rates of 7-day and 14-day standard triple therapies fall below 90% when clarithromycin resistance rate ⩾5%. Several strategies including bismuth-containing, non-bismuth-containing quadruple therapies (including sequential, concomitant, hybrid and reverse hybrid therapies), high-dose dual therapy and vonoprazan-based triple therapy have been proposed to increase the eradication rate of H. pylori infection. According to efficacy prediction model, the eradication rate of 14-day concomitant therapy, 14-day hybrid therapy and 7-day vonoprazan-based triple therapy is less than 90% if the frequency of clarithromycin-resistant strains is higher than 90%, 58% and 23%, respectively. To meet the recommendation of the consensus report and patients' expectation, local surveillance networks for resistance of H. pylori to clarithromycin are required to select appropriate eradication regimens in each geographic region. In areas with low (<5%) clarithromycin resistance (e.g. Sweden, Philippine, Myanmar and Bhutan), 7-day and 14-day standard triple therapies can be adopted for the first-line treatment of H. pylori infection with eradication rates of ⩾90%. In areas with high (⩾5%) clarithromycin resistance (most other countries worldwide) or unknown clarithromycin resistance, 14-day hybrid, 14-day reverse hybrid, 14-day concomitant and 10- to 14-day bismuth quadruple therapy can be used to treat H. pylori infection.

Declining trends of prevalence of Helicobacter pylori infection and incidence of gastric cancer in Taiwan: An updated cross-sectional survey and meta-analysis. Helicobacter 2022; 27:e12914. [PMID: 35848363 DOI: 10.1111/hel.12914] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 06/25/2022] [Accepted: 06/27/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND We aimed to assess the latest prevalence and secular trend of Helicobacter pylori infection and its association with the incidence and mortality of gastric cancer in Taiwan. MATERIALS AND METHODS Adults naive to H. pylori eradication received 13 C-urea breath test (13 C-UBT), H. pylori stool antigen test, and serology test during 2019-2020 in this prospective screening program. Children and adolescent aged between 7 and 19 years received 13 C-UBT for H. pylori screening. We also conducted a systematic review and meta-analysis to assess the secular trend of prevalence of H. pylori from 1990 to 2020 in Taiwan. The secular trends of age-standardized incidence and mortality of gastric cancer were obtained from the Taiwan Cancer Registry. RESULTS A total of 1494 participants were enrolled, including 294 children or adolescents and 1200 adults. The overall prevalence of active H. pylori infection by 13 C-UBT was 26.6% (397/1494), which was 30.8% in adults and 9.5% in adolescents/children. The age-standardized prevalence of active H. pylori infection was 32.3% in adults after adjustment of the population structure in Taiwan. Of the 29 studies including 38,597 subjects eligible for the meta-analysis, the pooled prevalence of H. pylori infection decreased from 63.8% (95% CI: 55.9%-71%) in 1990-2000 to 28.2% (95% CI:21.8%-35.6%) in 2016-2020. The age-standardized incidence and mortality of gastric cancer have also declined from 15.2 to 10.75 per 100,000, respectively, in 1999 to 9.29 and 5.4 per 100,000, respectively, in 2019. CONCLUSIONS The prevalence of H. pylori infection has declined in Taiwan, which correlates with the declining trends of age-standardized incidence and mortality of gastric cancer in Taiwan.

Abstract
Gastric cancer is an inflammation-related cancer triggered by Helicobacter pylori infection. Understanding of the natural disease course has prompted the hypothesis that gastric cancer can be prevented by administering a short-course antibiotic treatment to eradicate the H. pylori infection and interrupt this carcinogenic cascade. Results from randomized controlled trials and cohort studies have repeatedly confirmed this concept, which has moved attention from individual management of H. pylori infection to population-wide implementation of screening programs. Such a paradigm shift follows a three-tier architecture. First, healthcare policy-makers determine the most feasible and applicable eligibility, invitation, testing, referral, treatment, and evaluation methods for an organized screening program to maximize the population benefits and cost-effectiveness. Second, provision of knowledge and effective feedback to frontline general practitioners, including choice of diagnostic tests, selection of eradication regimens, and the indication of endoscopic examination, ensures the quality of care and increases the likelihood of desired treatment responses. Third, initiatives to raise population awareness are designed regarding the impact of H. pylori infection and risky lifestyle habits on the stomach health. These programs, with increased accessibility and geographic coverage in progress, will accelerate the decline in morbidity, mortality, and associated costs of this preventable malignancy.

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

Abstract
Background Serum pepsinogen (PG) is recommended as a screening test for premalignant gastric lesions. However, real-world evidence demonstrating its applicability and equivalence between different test brands is limited. Methods Mass screening began in 2018 in a high-risk Taiwanese population after eradication of Helicobacter pylori, with the first stage of two PG tests (GastroPanel®, Helsinki, Finland and LZ-Test®, Tokyo, Japan) and the second stage of endoscopy. A positive test was defined as PG-I < 30 ng/mL or PG-I/II ratio < 3 for GastroPanel® and PG-I ≤ 70 ng/mL and PG-I/II ratio ≤ 3 for LZ-Test®. Index lesions included atrophic gastritis and intestinal metaplasia. Test performance was evaluated based on the participation rate, positivity rate, referral rate, positive predictive value (PPV), and the detection rate. Results Among 7616 eligible participants, 5117 (67.2%) received PG tests and 284 (5.6%) tested positive. Of those who tested positive, 105 (37.0%) underwent endoscopy. Overall PPVs for atrophic gastritis and intestinal metaplasia were 12.4% and 18.9%, respectively, with detection rates of 2.5 and 3.9 per 1000, respectively. Correlations of numerical measures between tests were high and the agreements of test results were substantial. The PPVs (16.3% vs. 16.3% and 23.8% vs. 21.3%, P = 1.00 and 0.71, respectively), detection rates (2.5 vs. 2.5 and 3.7 vs. 3.3 per 1000, P = 1.00 and 0.27, respectively), and the stage distributions of gastritis were all comparable, which were confirmed by multiple regression analyses. Conclusions PG testing is effective for mass screening after eradication of H. pylori. Tests from different manufacturers, even using different analytical methods and cutoff criteria, can perform equivalently.

[PMID: 34721043 PMCID: PMC8553963 DOI: 10.3389/fphar.2021.759249] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 09/16/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Proton pump inhibitors (PPIs) are the first-line treatment for acid-related diseases. The pharmacokinetics and therapeutic efficacy of PPIs, however, are influenced by genetic factors such as variants in genes encoding drug-metabolizing enzymes (e.g., cytochrome P450 2C19 [CYP2C19]) and drug transporters. We performed a meta-analysis to evaluate the influence of CYP2C19 genotype and PPI class, PPI dose, treatment duration and clarithromycin dose on the cure rate of PPI-containing Helicobacter pylori eradication therapy. Methods: Randomized control trials (RCTs) investigating cure rates using a PPI-amoxicillin-clarithromycin regimen among different CYP2C19 genotypes through May 2021 were included. Results: A total of 25 studies (5,318 patients) were included. The overall eradication rate in the intention-to-treat analysis was 79.0% (3,689/4,669, 95% confidence interval [CI]: 77.8–80.2%), and that in CYP2C19 extensive metabolizers (EMs), intermediate metabolizer (IMs) and poor metabolizers (PMs) was 77.7% (1,137/1,464, 95% CI: 75.3–79.6%), 81.2% (1,498/1,844, 95% CI: 79.3–83.0%) and 86.8% (644/742, 95% CI: 83.9–88.9%), respectively. Meta-analysis showed that the relaTakashitive risk of failed eradication in CYP2C19 EMs compared with IMs and PMs was 1.21 (95% CI: 1.06–1.39, P = 0.006) and 1.57 (95% CI: 1.27–1.94, P < 0.001), respectively, in the fixed-effects model. The cure rate of omeprazole and lansoprazole-containing eradication regimens differed among CYP2C19 genotypes (P < 0.05), while that of rabeprazole and esomeprazole-containing regimens was similar. Conclusion: The cure rates of PPI-amoxicillin-clarithromycin H. pylori eradication regimen, especially those containing omeprazole and lansoprazole, differ among CYP2C19 genotypes. Therefore, selection of a second-generation PPI or tailored treatment may achieve higher eradication rates than first-generation PPI-amoxicillin-clarithromycin triple regimen.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. H. pylori is responsible for substantial gastrointestinal morbidity with a high disease burden. Since the revision of the H. pylori Clinical Practice Guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin based triple therapy. According to a nationwide randomized controlled study by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance to clarithromycin. The clinical practice guidelines for treatment of H. pylori were updated based on evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines were designed to provide clinical evidence for the treatment of H. pylori to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards, and will be revised if more evidence emerges in the future.

Abstract
As high clarithromycin resistance (>20%) in the Split-Dalmatia region of Croatia hinders the treatment of H. pylori infection, the primary objective of this study was to compare concomitant quadruple with the tailored, personalized therapy as first-line eradication treatment of H. pylori. In an open-label, randomized clinical trial, 80 patients with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 gr, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or tailored therapy in accordance with the results of the antimicrobial susceptibility testing. Eradication status was assessed 4 weeks after treatment. Eradication rates were significantly higher in tailored group than in concomitant group both in intention-to-treat (70 vs. 92.5%, p = 0.010) and per-protocol (87.5 vs. 100%, p = 0.030) analysis in the setting of increasing antibiotic resistance (clarithromycin 37.5%, metronidazole 17.5%, dual resistance 10%). Adverse effects were more frequent in the concomitant group (32.5 vs. 7.5%, p = 0.006). Tailored therapy achieves higher eradication with a lower adverse events rate. With the increasing resistance of H. pylori strains to antibiotic treatment, eradication regimes with such characteristics should be strongly considered as a reasonable choice for first-line treatment.

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

Abstract
BACKGROUND/PURPOSE Helicobacter pylori infection is one of the most common causes of peptic ulcer disease among children. This study is aimed to investigate the eradication rate of 14-day sequential therapy and the antibiotic resistance of H. pylori in children. METHODS Eighty-seven treatment-naïve children (55 males; median age, 13.5 years) with H. pylori infection from January 2009 to August 2019 were recruited in this study. The status of H. pylori infection was confirmed by culture or histology with the aid of urea rapid test or C-13 urea breathe test. Patients treated with either triple therapy for 7 days or 14 days, or sequential therapy for 14 days was analyzed retrospectively. RESULTS Thirty-eight (43.7%) patients received 14-day sequential therapy, 24 (27.6%) patients received 14-day triple therapy and the remaining 25 (28.7%) patients received 7-day triple therapy. The eradication rate of 14-day sequential therapy was significantly superior to 7-day triple therapy (97.4% vs. 80%, p = 0.032), and tended to be better than 14-day triple therapy (83%, p = 0.07). Of the 54 patients with available antibiotic resistance data, the resistant rate of clarithromycin, metronidazole, levofloxacin, and amoxicillin were 22.2%, 16.7%, 9.1% and 2.2%, respectively. Clarithromycin resistance demonstrated an inverse association with eradication success (Odds ratio = 0.017, p < 0.001). CONCLUSIONS In treatment-naïve children with H. pylori infection, 14-day sequential therapy is superior to triple therapy, and achieve a high eradication rate (above 90%) in an area of high clarithromycin resistance.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. Although the prevalence of H. pylori is gradually decreasing, approximately half of the world's population still becomes infected with this disease. H. pylori is responsible for substantial gastrointestinal morbidity worldwide, with a high disease burden. It is the most common cause of gastric and duodenal ulcers and gastric cancer. Since the revision of the H. pylori clinical practice guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin-based triple therapy for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance, especially from clarithromycin. The clinical practice guidelines for the treatment of H. pylori were updated according to evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after an expert consensus on three recommendations regarding the indication for treatment and eight recommendations for the treatment itself. These guidelines were designed to provide clinical evidence for the treatment (including primary care treatment) of H. pylori infection to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards and will be revised if more evidence emerges in the future.

Risk stratification for gastric cancer after Helicobacter pylori eradication: A population-based study on Matsu Islands. J Gastroenterol Hepatol 2021; 36:671-679. [PMID: 32671873 DOI: 10.1111/jgh.15187] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 06/13/2020] [Accepted: 07/12/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM The reliable method to stratify the gastric cancer risk after Helicobacter pylori eradication remains an elusive goal. METHODS Mass eradication of H. pylori began in 2004 in a high-risk population. After eradication, a screening program involving first-stage serological tests (pepsinogen-I, pepsinogen-II, H. pylori immunoglobin G, and gastrin-17) and second-stage endoscopic examination was launched in 2015-2018. Index lesions included gastric cancer or extensive premalignant lesions. We evaluated the performance of the serological tests to "rule in" and "rule out" the risk based on positive and negative likelihood ratios, respectively. The methylation levels of microRNA-124a-3 in the stomach were measured to indicate genetic damage. RESULTS Among 6512 invited subjects, 3895 (59.6%) participated. Both gastrin-17 and pepsinogen tests were normal in 3560 (91.4%) subjects; 206 (5.3%) gastrin-17 and 129 (3.3%) pepsinogen tests were abnormal. Years after eradication, the severity of gastritis had fallen greatly, and extensive premalignant lesions or gastric cancer frequently occurred in newly non-atrophic-appearing mucosa. Pepsinogen testing could moderately predict atrophic gastritis (positive likelihood ratio: 4.11 [95% confidence interval: 2.92-5.77]; negative likelihood ratio: 0.14 [0.10-0.19]). Gastrin-17 was not useful (0.66 and 1.20, respectively). However, pepsinogen testing poorly predicted the index lesions (2.04 [1.21-3.42] and 0.57 [0.34-0.95]). DNA methylation levels in the post-eradication mucosa were more discriminative for predicting index lesions (3.89 [2.32-6.54] and 0.25 [0.15-0.42]). CONCLUSIONS After eradication, pepsinogen false-negative results become more frequent because histology is improved but genetic damage may persist. Direct testing for genetic damage offers better discrimination.

Helicobacter 2021; 26:e12768. [PMID: 33089598 DOI: 10.1111/hel.12768] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 09/29/2020] [Accepted: 10/01/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND This study aimed to investigate whether an increased proton pump inhibitor (PPI) dose enhanced the efficacy of Helicobacter pylori (H. pylori) eradication and determine the appropriate cutoff intragastric pH value that could predict H. pylori eradication with bismuth-based quadruple therapy. MATERIALS AND METHODS A total of 207 H. pylori infected, treatment naive patients were enrolled in this prospective, open-label, randomized controlled trial. Patients were randomly allocated into Eso40-group (esomeprazole 40 mg bid) and Eso20-group (esomeprazole 20 mg bid), and their CYP2C19 genotyping status was assessed. The 24-h intragastric pH monitoring on day 7 was performed, and percentage of time gastric pH ≥ 3, ≥4, ≥5, and ≥6 (pH holding time ratios; HTRs) were measured. H. pylori eradication was evaluated using 13 C-urea breath test. RESULTS No significant difference in the eradication rates was observed between two groups. The median 24-h intragastric pH value was not significant different between two groups but the Eso40 Group had a significant higher pH4 HTRs (91.11% [95%CI: 87.50%-95.83%] vs. 95.83% [95.83%-100%]; p = .002). Additionally, the median 24-h intragastric pH value showed significantly difference between two groups in EM genotype (Eso20 Group 6.00 [95%CI; 5.75-6.15] vs. Eso40 Group 6.30 [6.05-6.30]; p = .019). Similar results were observed in pH4 HTRs. There were significant differences in intragastric pH value (6.10 [95%CI: 4.40-7.00] vs. 5.65 [4.85-5.95], p = .038) and in pH4 HTRs (96% [95%CI: 92.00%-96.00%] vs. 87.5% [67.00%-100.0%], p = .019) between eradication-successful and eradication-failed patients. Statistical analysis suggested that the median intragastric pH = 5.7 could identify the success of H. pylori eradication. CONCLUSIONS Bismuth-based quadruple therapy resulted in high H. pylori eradication rates either in PPI standard or double doses. Double dose of esomeprazole is associated with better intragastric acid suppression. A median 24-h intragastric pH of 5.7 could be appropriate cutoff value for predicting the successful H. pylori eradication.

Abstract
OBJECTIVE Although mass eradication of Helicobacter pylori has been proposed as a means to eliminate gastric cancer, its long-term effects remain unclear. DESIGN Mass eradication of H. pylori infection was launched in 2004 and continued until 2018 for a high-risk Taiwanese population aged 30 years or older dwelling on Matsu Islands with prevalent H. pylori infection. Test positives for the 13C-urea breath test underwent eradication therapy. We evaluated the effectiveness of the mass eradication in reducing two main outcomes, incidence and mortality rates of gastric cancer, until the end of 2016 and 2018, respectively. RESULTS After six rounds of mass screening and eradication, the coverage rate reached 85.5% (6512/7616). The referral rate for treatment was 93.5% (4286/4584). The prevalence rates of H. pylori fell from 64.2% to 15.0% with reinfection rates of less than 1% per person-year. The presence and severity of atrophic gastritis and intestinal metaplasia also decreased with time. Compared with the historical control period from 1995 to 2003, the effectiveness in reducing gastric cancer incidence and mortality during the chemoprevention period was 53% (95% CI 30% to 69%, p<0.001) and 25% (95% CI -14% to 51%, p=0.18), respectively. No significant changes were noted in the incidence rates of other digestive tract cancers or the antibiotic resistance rate of H. pylori. CONCLUSION Population-based eradication of H. pylori has significantly reduced gastric cancer incidence with no increase in the likelihood of adverse consequences. A significant reduction in mortality is likely to be achieved with a longer follow-up period. TRIAL REGISTRATION NUMBER NCT00155389.

Randomised clinical trial comparing concomitant and hybrid therapy for eradication of Helicobacter pylori infection. PLoS One 2020; 15:e0244500. [PMID: 33378403 PMCID: PMC7773256 DOI: 10.1371/journal.pone.0244500] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 12/09/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The primary objective of this study was to compare concomitant and hybrid therapy in the first line eradication treatment of Helicobacter pylori infection in Split-Dalmatia County, Croatia, in which clarithromycin resistance is above 20%. The secondary objective of the study was to determine and compare compliance and adverse events rate between these therapeutic protocols. MATERIALS AND METHODS In an open-label, randomised clinical trial 140 patients total with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 g, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or hybrid (esomeprazole 40 mg and amoxicillin 1 g twice daily during 14 days with adding metronidazole 500 mg and clarithromycin 500 mg twice daily, in the last 7 days,) treatment group. RESULTS Eradication rates for concomitant group and hybrid therapy group were 84.1% (58/69) and 83.1% (59/71) respectively in the intention-to-treat analysis and 96.7% (58/60) and 95.2% (59/62) in per-protocol analysis. There was no significant difference between the groups (ITT analysis: P = 0.878; PP analysis: P = 0.675). Adverse events were more frequent in the concomitant group (33.3% vs 18.3%, P = 0.043). There was no difference among groups regarding compliance rate. CONCLUSION Hybrid therapy has similar eradication rate as concomitant therapy, with lower adverse events rate. In the era of increasing antibiotic resistance, eradication regime with less antibiotic's usage, as hybrid therapy, should be reasonable first line treatment choice for H. pylori infection.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases worldwide. Although its incidence is gradually decreasing, about half of the world's population still get infected. H. pylori infection is responsible for substantial gastrointestinal morbidity worldwide. It is the most common cause of gastric and duodenal ulcers as well as gastric cancer. Since the revision of the H. pylori Clinical Practice Guidelines in 2013, the eradication rate of H. pylori has gradually decreased with the use of classical triple therapy, wherein amoxicillin, clarithromycin, and proton pump inhibitors are administered, for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was due to increased antimicrobial resistance induced by the use of antibiotics, especially clarithromycin. The update of clinical practice guideline for treatment of H. pylori was developed based on evidence-based medicine by conducting a meta-analysis. The draft recommendations were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines are designed to provide patients, nurses, medical school students, policymakers, and clinicians with clinical evidence to guide primary care and treatment of H. pylori infection. These may differ from current medical insurance standards and will be revised further, if necessary, based on research-based evidence.

Efficacy and Cost-effectiveness Comparison of 10-Day, 14-Day Sequential Versus 14-Day Triple Therapies for Treating Helicobacter pylori Infection in Egyptian Patients. J Clin Gastroenterol 2020; 54:806-812. [PMID: 31904681 DOI: 10.1097/mcg.0000000000001278] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/14/2022]
Abstract
GOALS The aim of this study was to clarify whether 10-day or 14-day sequential therapy (ST) can replace conventional triple therapy (TT) as a first-line treatment in Egypt. BACKGROUND Antimicrobial resistance has decreased the eradication rates for Helicobacter pylori infection worldwide. MATERIALS AND METHODS Patients who tested positive for H. pylori infection were randomly assigned to the 14-day triple-therapy group (n=34), 10-day ST group (n=34), or 14-day ST group (n=35). Sequential treatment includes lansoprazole 30 mg and amoxicillin 1000 mg, both twice for 5 or 7 days, followed by lansoprazole 30 mg, clarithromycin 500 mg, and tinidazole 500 mg, each twice for 5 or 7 days. Triple treatment consists of lansoprazole 30 mg, clarithromycin 500 mg, and amoxicillin 1000 mg, each twice for 14 days. Six weeks after treatment discontinuation, patients were examined by the urea breath test. Eradication rates, the incidence of adverse effects, compliance, and cost-effectiveness were evaluated. RESULTS The eradication rate was 90% with 10-day ST, 96.7% with 14-day ST, and 63.3% for TT (P=0.001). Mild tolerated adverse effects occurred in the 3 groups. The cost-effectiveness ratio was 2194 LE, 1241 LE, 1157 LE for standard triple therapy, 10-day, and 14-day ST, respectively. CONCLUSIONS Sequential therapies for 10 or 14 days are more cost-effective than standard TT, with 14-day ST being the most cost-effective. Accordingly, ST might replace TT as a first-line treatment for H. pylori infection in Egyptian patients.

Abstract
Poor adherence to treatment instructions may play an important role in the failure of Helicobacter pylori eradication. The aim of this study was to evaluate the effects of telephone-based reeducation on 14-day quadruple H. pylori eradication therapy. In total, 162 patients were randomly assigned (1 : 1) to either the intervention group (patients received telephone-based reeducation on the 4th, 7th, and 10th days of the course) or the control group (patients received instructions only at the time of getting the prescriptions). All patients received a 14-day quadruple H. pylori eradication therapy. The primary outcome was the H. pylori eradication rate. The secondary outcomes included the symptom relief rates and the incidence rates of adverse events. Seventy-five patients in the reeducation group and 74 patients in the control group completed the follow-up. The H. pylori eradication rate in the reeducation group was statistically higher than that in the control group (intention-to-treat: 72.8% vs. 50.6%, P = 0.006; per-protocol: 78.7% vs. 55.4%, P = 0.003). However, the symptom relief rates and the adverse event rates in these two groups were not significantly different. Overall, the results from this study suggest that telephone-based reeducation can be potentially applied to improve the H. pylori eradication rate in clinical practice, without significantly increasing the adverse effects.

Abstract
BACKGROUND Whether adjunctive N-acetylcysteine (NAC) may improve the efficacy of triple therapy in the first-line treatment of Helicobacter pylori infection remains unknown. Our aim was to compare the efficacy of 14-day triple therapy with or without NAC for the first-line treatment of H. pylori. MATERIAL AND METHODS Between 1 January 2014 and 30 June 2018, 680 patients with H. pylori infection naïve to treatment were enrolled in this multicenter, open-label, randomized trial. Patients were randomly assigned to receive triple therapy with NAC [NAC-T14, dexlansoprazole 60 mg four times daily (q.d.); amoxicillin 1 g twice daily (b.i.d.), clarithromycin 500 mg b.i.d., NAC 600 mg b.i.d.] for 14 days, or triple therapy alone (T14, dexlansoprazole 60 mg q.d.; amoxicillin 1 g b.i.d., clarithromycin 500 mg b.i.d.) for 14 days. Our primary outcome was the eradication rates by intention to treat (ITT). Antibiotic resistance and CYP2C19 gene polymorphism were determined. RESULTS The ITT analysis demonstrated H. pylori eradication rates in NAC-T14 and T14 were 81.7% [276/338, 95% confidence interval (CI): 77.5-85.8%] and 84.3% (285/338, 95% CI 80.4-88.2%), respectively. In 646 participants who adhered to their assigned therapy, the eradication rates were 85.7% and 88.0% with NAC-T14 and T14 therapies, respectively. There were no differences in compliance or adverse effects. The eradication rates in subjects with clarithromycin-resistant, amoxicillin-resistant, or either clarithromycin/amoxicillin resistant strains were 45.2%, 57.9%, and 52.2%, respectively, for NAC-T14, and were 66.7%, 76.9%, and 70.0%, respectively, for T14. The efficacy of NAC-T14 and T14 was not affected by CYP2C19 polymorphism. CONCLUSION Add-on NAC to triple therapy was not superior to triple therapy alone for first-line H. pylori eradication [ClinicalTrials.gov identifier: NCT02249546].

Abstract
Helicobacter pylori infection still represents a major health issue, especially in developing countries, with an estimate of 4 billion of infected subjects in 2015. The increase of antibiotic resistance has undermined the efficacy of standard triple therapy leading to more complex regimens. This review summarizes recommendations of international guidelines and reports the most recent evidence from meta-analyses and clinical trials on the treatment of Helicobacter pylori infection. The choice of H. pylori eradication regimen should be based on the local prevalence of clarithromycin resistance and the previous use of macrolides. Quadruple therapies (bismuth quadruple and concomitant) are the recommended regimens for the first-line treatment; a 14-day clarithromycin-containing triple therapy is suggested in areas with low prevalence of clarithromycin resistance and in patients without previous use of macrolides. Data on the efficacy of sequential therapy against clarithromycin resistant H. pylori strains are contradictory, and its use in the treatment of H. pylori infection is generally discouraged. Second-line treatments include levofloxacin-containing triple therapy and bismuth quadruple therapy. Probiotic supplementation should be used with the aim to reduce antibiotic-related adverse events. Recent evidence would support current guideline recommendations for the treatment of Helicobacter pylori infection.

Abstract
BACKGROUND The first-line eradication rate of standard triple therapy for Helicobacter pylori infection has declined to <80%, and alternative therapies with >90% success rates are needed. Inconsistent eradication rates were reported for proton pump inhibitor- and amoxicillin-containing high-dose dual therapy. OBJECTIVES We performed a prospective, randomized controlled study to assess the efficacy of esomeprazole- and amoxicillin-containing high-dose dual therapy and investigated the influencing clinical factors. PATIENTS AND METHODS We recruited 240/278 eligible H. pylori-infected patients after exclusion. They were randomly assigned to 14 day high-dose dual therapy (esomeprazole 40 mg three times daily and amoxicillin 750 mg four times daily for 14 days; EA group) or 7 day non-bismuth quadruple therapy (esomeprazole 40 mg twice daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily and metronidazole 500 mg twice daily for 7 days; EACM group). Urea breath tests were followed up 8 weeks later. RESULTS The eradication rates for the EA and EACM groups were 91.7% (95% CI = 85.3%-96.0%) and 86.7% (95% CI = 79.3%-92.2%) (P = 0.21) in ITT analysis; and 95.7% (95% CI = 90.2%-98.6%) and 92.0% (95% CI = 85.4%-96.3%) (P = 0.26) in PP analysis. The adverse event rates were 9.6% versus 23.0% in the two groups (P = 0.01). The H. pylori culture positivity rate was 91.8%. The antibiotic resistance rates were amoxicillin, 0%; clarithromycin, 14.6%; and metronidazole, 33.7%. CONCLUSIONS A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy achieves a high eradication rate as first-line anti-H. pylori therapy, comparable to that with 7 day non-bismuth quadruple therapy but with fewer adverse events.

Abstract
The rising prevalence of antibiotic resistance and the long-term safety following eradication therapy are important issues in the management of Helicobacter pylori infection. The prevalence of clarithromycin, levofloxacin, and metronidazole resistance of H. pylori has increased to 21%, 27%, and 45%, respectively, in the Asia-Pacific region. Personalized treatment guided by susceptibility testing may provide a reliably excellent eradication rate in the first-line treatment but is costly and not widely available. Population-specific empirical therapy according to the local prevalence of antibiotic resistance may be an alternative strategy. Levofloxacin-based therapy and bismuth quadruple therapy are the recommended second-line rescue therapy. Susceptibility testing or genotypic resistance-guided therapy is the preferred treatment for refractory H. pylori infection, but empirical therapy may be an acceptable alternative. Eradication of H. pylori leads to short-term perturbation of gut microbiota. The diversity of gut microbiota can be restored months after eradication therapy, but the speed of recovery varies with regimens. The short-term increases of antibiotic resistance of Escherichia coli and Klebsiella pneumoniae may be restored to basal states months after H. pylori eradication. Future studies that apply in-depth sequencing, such as shotgun metagenomics sequencing, are needed to clarify whether the compositions of gut microbiota at the species level are fully restored.

Abstract
BACKGROUND AND AIM There is little published research to examine the best approach to the management of Helicobacter pylori in Myanmar. This study aimed to determine the relative efficacy and tolerability of sequential eradication therapy compared to Myanmar's current recommendation of a concomitant four drug regimen. METHODS Patients were screened for H. pylori using monoclonal Stool Antigen Testing (SAT). Those testing positive were randomized 1:1 to receive receive Myanmar's first-line regimen of 14 days of concomitant rabeprazole, clarithromycin, amoxycillin and tinidazole (140 pills, cost US$23) or 10 days of sequential rabeprazole, clarithromycin, amoxycillin and tinidazole (60 pills, cost US$10). Adherence and adverse effects were recorded, and the efficacy of the regimens assessed with repeat SAT. RESULTS Of the 1011 patients screened for H. pylori infection, 313 (31%) tested positive. There was no statistical difference in the cure rates of the two regimens in either intention-to-treat: 128/157 (82%; 95% confidence interval (CI): 75-87%) receiving sequential therapy versus 123/156 (79%; 95% CI: 72-85%) receiving concomitant therapy (P = 0.55) or per-protocol analysis: 125/131 (95%; 95% CI: 90-98) receiving sequential therapy versus 121/130 (93%; 95% CI: 87-96) receiving concomitant therapy (P = 0.42). Side effects of therapy were reported in 54/157 (47%) patients taking sequential therapy compared with 62/156 (53%) taking concomitant therapy, but this difference did not reach statistical significance (P = 0.33). CONCLUSIONS In this high-burden, resource-poor setting, less expensive sequential therapy was as effective and as well tolerated as the currently recommended concomitant four drug regimen for eradication of H. pylori.

Abstract
Helicobacter pylori is one of the most widespread infections involved in the pathogenesis of chronic gastritis, peptic ulcer, and gastric cancer. Hence, there is an urgent need to develop medications against H. pylori. This study aimed to evaluate synergistic effect of Rubus crataegifolius (RF) and Ulmus macrocarpa Hance (UL) against H. pylori. Antibacterial susceptibility of each extract either separately or in combination was studied against two H. pylori standard strains and 11 clinical isolates using agar dilution method. The effect of the extracts on H. pylori inoculated Balb/c mice model was also studied using single dosing (100 mg/kg each) approach. The MIC50 of RF and UL were more than 100 and 200 µg/ml, respectively, against the tested strains. However, simultaneous treatment with RF and UL at 75 and 50 µg/ml, respectively, showed decreased viable cell number, MIC70, and at 75 µg/ml each showed synergic effect with MIC90. On H. pylori inoculated Balb/c mice model, RF and UL separately (100 mg/kg each) showed moderate anti-H. pylori effect, while simultaneous treatment of RF and UL with same dose showed significant synergistic anti-gastric effects in stomach. The results showed a significant synergistic effect of plants extract against H. pylori infection and eventually gastric mucosal damage. Our finding could be considered a valuable support in the treatment of H. pylori induced gastritis and may contribute to the development of new and safe combined herbal product as anti-H. pylori regimens.

Abstract
Helicobacter pylori are etiological agents in the development of gastritis, gastroduodenal ulcers, gastric cancer, and mucosa-associated lymphoid tumors. Our previous investigations demonstrated that standardized combined plants extracts (Rubus crataegifolius and Ulmus macrocarpa) inhibit the growth of H. pylori in in vitro experiments. Also, we demonstrated that Gardenia jasminoides is effective in preventing gastritis and gastric ulcers in animal experiments. In the present work, we tested the standardized combined three plant extract (RUG-com) on the mouse model of H. pylori infectious disease to examine the effects of RUG-com on both the prevention and curing on the stomachs of infected mice. After the final administrations, biopsy samples of gastric mucus were assayed for bacterial numbers, biochemical analysis, inflammatory scores, and histology. Treatment with standardized plants extracts, single or combined, reduced the H. pylori load compared with the control. Treatment also significantly (P<0.05) reduced both acute and chronic mucosal and subacute inflammation, and epithelial cell degeneration and erosion induced by H. pylori infection. Further investigations demonstrated that H. pylori-induced inflammation was decreased by RUG-com extracts via down regulating cyclooxygenase-2 and inducible nitric oxide synthase pro-inflammatory gene expression. Our results suggest that RUG-com is useful to prevent H. pylori infection, H. pylori-induced inflammation and associated gastric damage.

Abstract
BACKGROUND Helicobacter pylori eradication has been shown to decrease gastric adenocarcinoma risk. The epidemiology of gastric lymphoma, which is also associated with H. pylori, and other rare subtypes of gastric cancer is less clear. This study comprehensively evaluated the incidence trend and the survival of gastric cancer in Taiwan by histologic subtype. METHODS The incidence trends of gastric cancer in Taiwan from 1996 and 2013 were evaluated using data from the Taiwan Cancer Registry. The life-table method and the Cox proportional hazards analysis were used to evaluate the survival of gastric cancer. RESULTS The incidence of all gastric cancers in Taiwan decreased from 15.97 per 100,000 in 1996 to 11.57 per 100,000 in 2013. The most frequent histologic subtype of gastric cancer in Taiwan was adenocarcinoma, followed by lymphoma and sarcoma (mainly gastrointestinal stromal tumor). The best survival was in patients with sarcoma, followed by lymphoma, neuroendocrine tumor, and adenocarcinoma. Generally, women had a better survival than men. The incidence of adenocarcinoma significantly decreased from 13.56 per 100,000 in 1996 to 9.82 per 100,000 in 2013 (P < 0.0001). In contrast, the incidences of mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma did not decrease. CONCLUSIONS The incidence of adenocarcinoma and lymphoma, both of which are associated with H. pylori, showed diverging trends. The survival of gastric cancer differed by histologic subtype and sex. IMPACT The disparity in the incidence trends between gastric lymphoma and adenocarcinoma, both associated with H. pylori, warranted the need to search for additional risk factors of gastric lymphoma.

Helicobacter pylori eradication improves glycemic control in type 2 diabetes patients with asymptomatic active Helicobacter pylori infection. J Diabetes Investig 2019; 10:1092-1101. [PMID: 30556347 PMCID: PMC6626959 DOI: 10.1111/jdi.12991] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 12/04/2018] [Accepted: 12/13/2018] [Indexed: 12/29/2022] Open
Abstract
AIMS/INTRODUCTION Helicobacter pylori infection is associated with insulin resistance and glycemia in non-diabetes. However, the relationship between H. pylori infection and glycemia in diabetes remains inconclusive. Therefore, we explored the effect of H. pylori infection status and its eradication on glycemic control and antidiabetic therapy in type 2 diabetes patients. MATERIALS AND METHODS A total of 549 diabetes patients were recruited for sequential two-step approach (immunoglobulin G [IgG] serology followed by 13 C-urea breath test [UBT]) to discriminate "active" (IgG+ and UBT+) from "non-active" (UBT- or IgG-) H. pylori infection, and "past" (IgG+ but UBT-) from "never/remote" (IgG-) infection. The differences in hemoglobin A1c (A1C) and antidiabetic regimens between groups were compared. In the "active" infection group, the differences in A1C changes between participants with and without 10-day eradication therapy were compared after 3 months. RESULTS Despite no between-group difference in A1C, the "active" infection group (n = 208) had significantly more prescriptions of oral antidiabetic drug classes (2.1 ± 1.1 vs 1.8 ± 1.1, P = 0.004) and higher percentages of sulfonylurea use (67.3% vs 50.4%, P < 0.001) than the "non-active" infection group (n = 341). There were no differences in A1C and oral antidiabetic drug classes between "past" (n = 111) and "never/remote" infection groups (n = 230). Compared with the non-eradication group (n = 99), the eradication group (n = 98) had significant within-group (-0.17 ± 0.80%, P = 0.036) and between-group (-0.23 ± 0.10%, P = 0.024) improvements in A1C. CONCLUSIONS Diabetes patients with active H. pylori infection need higher glycemic treatment intensity to achieve comparable glycemia. Furthermore, H. pylori eradication decreases A1C, and thus improves glycemic control.

Abstract
AIMS There are no studies looking at the relationship between colonoscopy withdrawal time (CWT) and adenoma detection rate (ADR) in non-screening patients. Our aim is to explore the relationship between CWT and ADR, particularly in the proximal colon where colonoscopy is shown to be less protective for the development of cancers. METHODS This is a retrospective study during November 2015 to December 2016 of non-screening colonoscopies done at a large teaching hospital. Incomplete and therapeutic procedures were excluded. The 39 endoscopists included were 15 gastroenterologists, 10 colorectal surgeons and 14 trainee colonoscopists. CWT was calculated by reviewing caecal intubation and rectal retroflexion images. RESULTS 783 colonoscopies were included, with mean patient age of 58.51 years (SD 15.5). The mean ADR was 21.45% in the study. The CWT could be calculated for 62.83% of the cases (n=492). 80% (393) of colonoscopies had CWT of ≥6 min. Mean CWT was 9.15 min (SD 4.4). The ADR positively correlated with longer CWT (r=0.31, p=0.0001). The ADR was significantly higher when CWT was ≥8 min compared with CWT <6 min or CWT of 6-8 min (p=0.0001). More polyps were detected in the proximal colon when CWT ≥8 min (p=0.078). Mean CWT of gastroenterologists was 9.8 min (SD 4.5), similar to the trainee group (10.3 min, SD 3.8), while mean CWT for colorectal surgeons was 5.7 min (SD 3.2). The ADR for gastroenterologists was 25.9% versus 17.5% for colorectal surgeons and 17.8% for trainees. CONCLUSIONS There is a moderately strong positive correlation between longer CWT and ADR in non-screening colonoscopies. CWT can differ between different endoscopists. Meticulous colonoscopy withdrawal may improve polyp detection in the proximal colon.

Abstract
Despite extensive studies on the gastric microbiota, including Helicobacter pylori and non-H. pylori, the bacterial composition in children remains unknown. In this study, we analyzed the culturable gastric bacteria in stomach biopsies from 346 children aged 1-15 years affected by gastric diseases. H. pylori and non-H. pylori were identified by specific PCR and 16S rDNA sequencing, respectively. Antibiotic susceptibilities of H. pylori and non-H. pylori were tested by the E-test and disk diffusion methods, respectively. Rapid diagnosis was also performed by H. pylori-specific PCR. Twenty-two H. pylori strains were obtained from culture, and 92 biopsies were positive by H. pylori-specific PCR. The positive rate was higher in boys (40.3%) than in girls (23.3%) (P = 0.001). Resistance rates of 22 H. pylori strains were as follows: metronidazole, 86.4%; tetracycline, 22.7%; amoxicillin, 22.7%; levofloxacin, 31.8%; clarithromycin, 36.4%. Ten isolates were multidrug-resistant. Additionally, among 366 non-H. pylori strains, 204 exhibited urease activity. Non-H. pylori resistance rates were as follows: metronidazole, 94.8%; tetracycline, 26.2%; amoxicillin, 42.6%; levofloxacin, 15.3%; clarithromycin, 46.7%. Our results showed that children with gastric disorders harbor stomach bacteria with urease activity or nitrate reductase activity. Further studies will determine the effects of non-H. pylori bacteria in gastric diseases.

Abstract
BACKGROUND Striking prevalence of Helicobacter pylori infection has been convoluted with considerable resistance to various antibiotics worldwide. Although many eradication regimens have been introduced as the first-line therapies against H pylori, lack of appropriate multiple comparison studies makes hard to implement such results to the clinical practice. This project attempts to utilize a comprehensive network meta-analysis to pool the results of clinical trial comparing various first-line eradication therapies simultaneously in different continents. METHODS We will include all randomized controlled trials assessing the first-line regimens for treatment of H pylori published in last 10 years. We will search the databases of PubMed, EMBASE, Scopus, Web of Science and Cochrane Central Register of Controlled Trials, International Standard Randomised Controlled Trial Number registry, World Health Organisation International Clinical Trials Registry Platform, and ClinicalTrials.gov for randomized controlled trials published since January 2009 without language limitation. The primary and secondary outcomes will be H pylori eradication rate and adverse events, respectively. Subgroup analyses will be conducted for different continents. Two reviewers will independently contribute in study selection and data extraction. For evaluating quality of studies, Cochrane Collaboration tool score will be used. We will conduct network meta-analysis for treatment comparisons using STATA software version 13. RESULTS These findings will be submitted to a peer-reviewed journal for publication. CONCLUSION Our results will provide the guidance for clinicians in deferent regions to select the best possible therapeutic regimen for treatment of H pylori infected patients.

Abstract
BACKGROUND & AIMS In 2017, the World Health Organization (WHO) designated clarithromycin-resistant Helicobacter pylori a high priority for antibiotic research and development. However, there are no clear data on the global distribution of resistance or its clinical effects. We performed a systematic review and meta-analysis to assess the distribution of H pylori resistance to commonly used antibiotics and to measure the association between antibiotic resistance and treatment failure. METHODS We searched publication databases for studies that assessed rates of H pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline. Pooled estimates of primary and secondary resistance and 95% confidence intervals (CIs) were grouped by WHO region. The association between antibiotic resistance and treatment failure was measured by extracting data on treatment efficacy in patients with resistant and susceptible isolates and pooling odds ratios with 95% CIs. RESULTS We identified 178 studies, comprising 66,142 isolates from 65 countries. Primary and secondary resistance rates to clarithromycin, metronidazole, and levofloxacin were ≥15% in all WHO regions, except primary clarithromycin resistance in the Americas (10%; 95% CI, 4%-16%) and South-East Asia region (10%; 95% CI, 5%-16%) and primary levofloxacin resistance in the European region (11%; 95% CI, 9%-13%). There was considerable heterogeneity (I2 > 75%) among all analyses-this might have resulted from the grouping of resistance rates by country. Increasing antibiotic resistance was observed in most WHO regions. Resistance to clarithromycin was significantly associated with failure of clarithromycin-containing regimens (odds ratio, 6.97; 95% CI, 5.23-9.28; P < .001). CONCLUSIONS Resistance of H pylori to antibiotics has reached alarming levels worldwide, which has a great effect on efficacy of treatment. Local surveillance networks are required to select appropriate eradication regimens for each region.

Liou JM, Chen PY, Kuo YT, Wu MS. Toward population specific and personalized treatment of Helicobacter pylori infection. J Biomed Sci 2018; 25:70. [PMID: 30285834 PMCID: PMC6167866 DOI: 10.1186/s12929-018-0471-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Accepted: 09/03/2018] [Indexed: 02/06/2023] Open
Abstract
In the face of rising prevalence of antibiotic resistance, susceptibility testing to provide personalized treatment is recommended prior to eradication therapy for Helicobacter pylori (H. pylori). Yet, population specific treatment according to the local prevalence of antibiotic resistance may be an alternative if susceptibility testing is not available. In this article, we reviewed the global prevalence of primary antibiotic resistance and the efficacies of commonly used regimens in antibiotic susceptible and resistance strains. We then constructed a model to predict the efficacies of these regimens and proposed an algorithm to choose the optimal first-line and rescue therapies according to the prevalence of antibiotic resistance. Clarithromycin-based therapy (triple, sequential, concomitant, and hybrid therapies) for 14 days remains the treatment of choice in regions with low clarithromycin resistance (≤15%) and bismuth quadruple therapy may be an alternative therapy. In regions with high clarithromycin resistance (> 15%), bismuth quadruple therapy is the treatment of choice and non-bismuth quadruple therapy may be an alternative. Either levofloxacin-based therapy or bismuth quadruple therapy may be used as second-line rescue therapy for patients fail after clarithromycin-based therapies, whereas levofloxacin-based therapy may be used for patients fail after bismuth quadruple therapy. Susceptibility testing or genotypic resistance should be determined after two or more eradication failures. However, empirical therapy according to prior medication history to avoid the empirical reuse of levofloxacin and clarithromycin may be an acceptable alternative after consideration of cost, patient preference, and accessibility. Rifabutin-based therapy for 14 days may serve as the fourth-line therapy. New antibiotics specific for H. pylori are highly anticipated.

Systematic Review with Meta-Analysis: Concomitant Therapy vs. Triple Therapy for the First-Line Treatment of Helicobacter pylori Infection. Am J Gastroenterol 2018; 113:1444-1457. [PMID: 30171216 DOI: 10.1038/s41395-018-0217-2] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2018] [Accepted: 06/29/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Whether concomitant therapy is superior to triple therapy of various treatment lengths for the first-line treatment of H. pylori remains controversial. The objective of this study is to compare the efficacy of concomitant therapy and triple therapy given for 5-14 days. METHODS Randomized control trials (RCTs) comparing the efficacy of concomitant therapy for 5-14 days and proton pump inhibitor-amoxicillin-clarithromycin (PAC)-based triple therapy for 5-14 days in the first-line treatment of adult patients with H. pylori infection published from 1990 to January 2018 were searched from the PubMed, Cochrane Library, and Embase. Abstracts from international annual conferences were also searched. The primary and secondary outcomes were the eradication rate according to the intention-to-treat analysis and the adverse effects, respectively. Subgroup analyses were also performed according to treatment length. This study is registered with PROSPERO, number CRD42017081328. RESULTS Of the 639 articles identified, 23 RCTs including 3305 patients in the concomitant therapy group and 3327 patients in the triple therapy group were eligible. Overall, concomitant therapy was superior to triple therapy [risk ratio (RR): 1.15; 95% confidence interval (CI): 1.09-1.21; p < 0.001]. However, there were significant heterogeneity (I2 = 74.0%, p < 0.001). In the subgroup analysis, 5-day concomitant therapy was superior to 5-day triple therapy (RR: 1.30; 95% CI: 1.04-1.62; p = 0.02), 5- or 7-day concomitant therapy was superior to 7-day triple therapy (RR: 1.16; 95% CI: 1.12-1.21; p < 0.001), and 5- or 7-, or 10- or 14-day concomitant therapy was superior to 10-day triple therapy (RR: 1.15; 95% CI: 1.08-1.23; p < 0.001). However, 5- or 10-day concomitant therapy was not superior to 14-day triple therapy (RR: 1.02; 95% CI: 0.89-1.16; p = 0.796). The frequency of adverse effects was significantly higher in concomitant therapy than triple therapy (RR: 1.19; 95% CI: 1.06-1.34; P = 0.004). CONCLUSIONS Concomitant therapy given for 5 or 10 days was superior to 5- or 7-, or 10-day PAC-based triple therapy, but was not superior to 14-day triple therapy.

Abstract
BACKGROUND & AIMS We aimed to compare the efficacy of genotypic resistance-guided therapy vs empirical therapy for eradication of refractory Helicobacter pylori infection in randomized controlled trials. METHODS We performed 2 multicenter, open-label trials of patients with H pylori infection (20 years or older) failed by 2 or more previous treatment regimens, from October 2012 through September 2017 in Taiwan. The patients were randomly assigned to groups given genotypic resistance-guided therapy for 14 days (n = 21 in trial 1, n = 205 in trial 2) or empirical therapy according to medication history for 14 days (n = 20 in trial 1, n = 205 in trial 2). Patients received sequential therapy containing esomeprazole and amoxicillin for the first 7 days, followed by esomeprazole and metronidazole, with levofloxacin, clarithromycin, or tetracycline (doxycycline in trial 1, tetracycline in trial 2) for another 7 days (all given twice daily) based on genotype markers of resistance determined from gastric biopsy specimens (group A) or empirical therapy according to medication history. Resistance-associated mutations in 23S ribosomal RNA or gyrase A were identified by polymerase chain reaction with direct sequencing. Eradication status was determined by 13C-urea breath test. The primary outcome was eradication rate. RESULTS H pylori infection was eradicated in 17 of 21 (81%) patients receiving genotype resistance-guided therapy and 12 of 20 (60%) patients receiving empirical therapy (P = .181) in trial 1. This trial was terminated ahead of schedule due to the low rate of eradication in patients given doxycycline sequential therapy (15 of 26 [57.7%]). In trial 2, H pylori infection was eradicated in 160 of 205 (78%) patients receiving genotype resistance-guided therapy and 148 of 205 (72.2%) patients receiving empirical therapy (P = .170), according to intent to treat analysis. The frequencies of adverse effects and compliance did not differ significantly between groups. CONCLUSIONS Properly designed empirical therapy, based on medication history, is an acceptable alternative to genotypic resistance-guided therapy for eradication of refractory H pylori infection after consideration of accessibility, cost, and patient preference. ClinicalTrials.gov ID: NCT01725906.

Comparison of Levofloxacin-Based, 10-day Sequential Therapy with 14-day Quadruple Therapy for Helicobacter Pylori Eradication: A Randomized Clinical Trial. Middle East J Dig Dis 2018; 10:242-248. [PMID: 31049172 PMCID: PMC6488509 DOI: 10.15171/mejdd.2018.117] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2018] [Accepted: 09/02/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND
Considering the importance of Helicobacter pylori (H. pylori) eradication, this clinical trial
was designed to prospectively evaluate the efficacy of levofloxacin-based, sequential therapy in
comparison with quadruple therapy for eradicating H. pylori.
METHODS
Overall 156 patients with dyspepsia and H. pylori infection were included in this study and
were randomly allocated to either 10-day sequential therapy group (group A) to receive pantoprazole
(40 mg twice daily), amoxicillin (1 gr twice daily), levofloxacin (500 mg twice daily), and
tinidazole (500 mg twice daily) (PALT) or 14-day quadruple therapy group (group B) to receive
pantoprazole, clarithromycin, bismuth subcitrate, and amoxicillin (PABC). At the end of the study
the eradication rate in each group was assessed by urea breath test (UBT).
RESULTS
Age range of the participants was 18-65 years (average 36.9 years) and 50% of them (78
patients) were men. 78 patients were allocated to group A and 78 patients to groupe B. After antibiotic
therapy, all the patients received acid suppression therapy with Proton Pump Inhibitor (PPI)
for 4 weeks and then the eradication rate was confirmed by UBT (Heli FAN plus 13C, Germany).
Before performing UBT, all the participants were requested to halt consumption of PPI for at least
1 week. During the treatment there was not any major complication but in group A (sequential
therapy), two patients complained of minor complications including musculoskeletal pain. None
of the patients in group B had any complaint or side effect.
The rate of H. pylori eradication in group A was 78.2% (61 patients) while this rate in group B was
83.3% (65 patients) with no significant difference between the two groups (p = 0.42). In subgroup
analysis, the rate of eradication among men in group A and B were 76.9% and 89.7%, respectively
(p = 0.22) while the eradication rate among women were 79.4% and 76.9%, respectively (p = 1.00).
CONCLUSION
It seems that levofloxacin base sequential therapy does not have any advantage in comparison
with quadruple regimen and until finding any more effective short course therapy for H. Pylori
eradication; we encourage quadruple regimen to be used as the first line therapy.

Abstract
ABSTRACT Significant progress has been obtained since the III Brazilian Consensus Conference on H. pylori infection held in 2012, in Bento Gonçalves, Brazil, and justify a fourth meeting to establish updated guidelines on the current management of H. pylori infection. Therefore, the Núcleo Brasileiro para Estudo do Helicobacter pylori e Microbiota (NBEHPM), association linked to Brazilian Federation of Gastroenterology (FBG) held its fourth meeting again in Bento Gonçalves, RS, Brazil, on August 25-27, 2017. Twenty-six delegates, including gastroenterologists, endoscopists, and pathologists from the five regions of Brazil as well as one international guest from the United States, participated in the meeting. The participants were invited based on their knowledge and contribution to the study of H. pylori infection. The meeting sought to review different aspects of treatment for infection; establish a correlation between infection, dyspepsia, intestinal microbiota changes, and other disorders with a special emphasis on gastric cancer; and reassess the epidemiological and diagnostic aspects of H. pylori infection. Participants were allocated into four groups as follows: 1) Epidemiology and Diagnosis, 2) Dyspepsia, intestinal microbiota and other afections, 3) Gastric Cancer, and, 4) Treatment. Before the consensus meeting, participants received a topic to be discussed and prepared a document containing a recent literature review and statements that should be discussed and eventually modified during the face-to-face meeting. All statements were evaluated in two rounds of voting. Initially, each participant discussed the document and statements with his group for possible modifications and voting. Subsequently, during a second voting in a plenary session in the presence of all participants, the statements were voted upon and eventually modified. The participants could vote using five alternatives: 1) strongly agree; 2) partially agree; 3) undecided; 4) disagree; and 5) strongly disagree. The adopted consensus index was that 80% of the participants responded that they strongly or partially agreed with each statement. The recommendations reported are intended to provide the most current and relevant evidences to management of H. pylori infection in adult population in Brazil.

Abstract
BACKGROUND Helicobacter pylori infection is still frequent in the community and all infected subjects should be offered an eradication therapy. Nowadays physicians have to face the challenge of antibiotic resistance in treating Helicobacter pylori-infected individuals. AIM This review provides an overview of current international guidelines and reports recent evidence from systematic reviews and clinical trials on the treatment of Helicobacter pylori infection and should help physicians to better treat their patients. RESULTS General rules to optimize the management of Helicobacter pylori infection include: (i) considering previous patient's exposure to antibiotics; (ii) using high dose of proton-pump inhibitors; and (iii) avoiding repeating the same regimen, if it has already failure. Bismuth quadruple therapy and concomitant therapy are the best first-line empirical treatments in areas with high clarithromycin resistance and in individuals with previous use of macrolides; otherwise, the 14-day clarithromycin-containing triple therapy is a valid regimen. The sequential therapy is no longer a suggested treatment by international guidelines. CONCLUSIONS Current international guidelines are consistent in defining treatment strategies for Helicobacter pylori infection. The use of national registries to monitor the efficacy and tolerability of different regimens in the real world of clinical practice is now needed.
