Nyssen OP, Martínez B, Mégraud F, Savarino V, Fallone CA, Bazzoli F, Gisbert JP. Sequential versus Standard Triple Therapy for First-Line Helicobacter pylori Eradication: An Update. 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.

Abstract
The Helicobacter pylori infection is a significant issue in global health as it is associated with a range of gastrointestinal disorders and an elevated likelihood of developing stomach cancer. The declining efficacy of standard triple therapy (TT) as the recommended treatment can be attributed to the emergence of drug-resistant strains. Sequential therapy (ST) has been recognized as an alternative approach, wherein a combination of proton-pump inhibitor (PPI) and amoxicillin is administered for the initial five days, followed by a combination of PPI, clarithromycin, and metronidazole for the subsequent five days. In this comprehensive systematic review and meta-analysis, we have thoroughly assessed the effectiveness and tolerability of ST as a primary treatment option in comparison to TT for the eradication of H. pylori. The analysis comprised a total of 15 randomized controlled trials, encompassing a sample size of 5,219 patients. The collective findings indicate that ST exhibits promise as it achieves higher rates of eradication. Additionally, it is worth noting that this approach has the potential to yield cost savings and enhance treatment compliance when compared to TT. To summarize, this systematic review and meta-analysis provide evidence that ST is a viable option for the initial treatment of H. pylori eradication. It shows potential benefits compared to the standard TT, especially when there is resistance to clarithromycin. In order to establish ST as the preferred first-line treatment, it is imperative that additional research be conducted to address the aforementioned limitations and thoroughly investigate its long-term efficacy and safety profiles. Nevertheless, it is required that additional research be conducted in order to adequately tackle the constraints of the current studies and solidify its position as a favored treatment alternative. It is also essential to consider ST as a viable approach to improve the rates of H. pylori eradication. This method should be thoroughly examined in clinical practice to gain a deeper understanding of its effectiveness.

Abstract
Introduction: Helicobacter pylori (H. pylori) colonization is prevalent all over the world, and it is associated with low socioeconomic status, poor hygiene, and overcrowding. Its eradication is important since it is an etiologic agent for gastritis, peptic ulcer, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. Different regimens are available for the eradication of H. pylori and include triple therapy and sequential therapy. Our study aims to compare the efficacy of triple therapy versus sequential therapy in the eradication of H. pylori. Material and methods: This randomized clinical trial was conducted at the Pakistan Institute of Medical Sciences Hospital, Islamabad, from September 2016 to September 2017 after the approval of the institutional review board. A total of 160 patients were enrolled and equally divided into two, group A and group B. A twice-daily dose of amoxicillin 1,000 mg, rabeprazole 20 mg, and clarithromycin 500 mg was given to group A for 10 days, while group B was initially given rabeprazole 20 mg and amoxicillin 1,000 mg two times daily for the first five days (i.e., induction phase), followed by triple therapy that included rabeprazole 20 mg, clarithromycin 500 mg, and metronidazole/tinidazole 500 mg twice daily for the next five days. A negative stool antigen test performed four weeks after the completion of therapy was considered an effective eradication. A proforma was used to collect data that included age, gender, city or province of residence, family income, group (group A or group B), and eradication efficacy. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). Results: A total of 160 patients were included, with mean age and standard deviation of 40.02±24.4 years. The male/female ratio was 1.8:1. Successful eradication of H. pylori achieved in group A was 67.5% (N=54) in comparison to group B, which was 95% (N=76) (p=0.001). Conclusion: Sequential therapy was superior to triple therapy in H. pylori eradication.

Abstract
Introduction: Helicobacter pylori-induced chronic infection is associated with peptic ulcer, chronic gastritis, gastric cancer, and increasing antibiotic resistance. We aimed to evaluate the efficacy of clarithromycin-based triple therapy and non-bismuth based quadruple therapy for eradicating H. pylori in patients with chronic gastritis in Kuwait. Methods: We enrolled a total of 603 treatment-naive dyspeptic patients with gastric biopsy-proven chronic gastritis secondary to H. pylori in a prospective, open-label, randomized study. Patients were randomized into two groups: a group received the standard triple therapy (omeprazole, amoxicillin, and clarithromycin) for 14 days and a group received quadruple therapy (omeprazole, amoxicillin, clarithromycin, and metronidazole) for 14 days. All patients were tested for the eradication of H. pylori by carbon-13 urea breath test 1 month after eradication therapy. Results: The overall eradication rate was 63.2%. The eradication rates in intention-to-treat (ITT) and per protocol (PP) population were 58.4% and 64.6%, respectively, in triple therapy group. In the quadruple therapy group, the eradication rates in ITT and PP population were 68.0% and 78.5%, respectively, with a statistically significant higher eradication rate in patients treated by quadruple therapy than the triple therapy (P < 0.01). Multivariate logistic regression analysis revealed that treatment regimen was the only significant predictor for successful H. pylori eradication. The most common adverse events were abnormal taste, headache, dizziness, and abdominal pain. Conclusion: Non-bismuth based quadruple therapy is more effective than standard clarithromycin-based triple therapy for eradicating H. pylori in patients with chronic gastritis.

Long-term changes in the gut microbiota after triple therapy, sequential therapy, bismuth quadruple therapy and concomitant therapy for Helicobacter pylori eradication in Chinese children. Helicobacter 2021; 26:e12809. [PMID: 33899288 DOI: 10.1111/hel.12809] [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: 02/03/2021] [Revised: 03/29/2021] [Accepted: 04/01/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND We previously reported that the administration of 14-day standard triple therapy (TT), sequential therapy (ST), bismuth-based quadruple therapy (BT), and concomitant therapy (CT) as the first-line therapy for Helicobacter pylori infection in Chinese children achieved eradication rates of 74.1%, 69.5%, 89.8%, and 84.6%, respectively. In this follow-up study, we further evaluated the short- and long-term effects of the four regimens on the gut microbiota in these children. METHODS We prospectively recruited treatment-naïve children with H. pylori infection. Fecal samples were collected at week 0, 2, 6, and 52, and alterations in the gut microbiota were analyzed by 16S rRNA gene sequencing. RESULTS Sixty-three patients participated in this study (16 with TT, 15 with ST, 16 with BT and 16 with CT). At week 2, the alpha diversity (Shannon and Chao 1 index) was significantly reduced in the TT (p = 0.008, p < 0.001), ST (p < 0.001, p < 0.001), BT (p < 0.001, p < 0.001) and CT groups (p < 0.001, p < 0.001). Some changes persisted in the ST, BT, and CT groups at week 6, and all were restored (expect p = 0.02 with Chao 1 index in the CT group) at week 52. The beta diversity was significantly changed in the BT (p = 0.001) and CT groups (p = 0.001) 2 weeks post-eradication and restored 1 year after therapy. Immediately after therapy, the relative abundance of Proteobacteria was strikingly increased in the ST (p = 0.005), BT (p < 0.001) and CT groups (p < 0.001), and the genus-level analysis showed that the abundances of 23.1%, 43.3%, 78.6%, and 78% of the bacterial genera in the TT, ST, BT, and CT groups were significantly changed. All these changes returned to almost the pre-eradication level 1 year post-eradication. CONCLUSION Eradication of H. pylori infection can lead to transient dysbiosis of gut microbiota, and these changes almost recovered 1 year post-eradication, which indicates the long-term safety of H. pylori therapy.

Abstract
BACKGROUND & AIMS A number of double, triple, and quadruple therapies have been proposed as first-line empiric treatments for Helicobacter pylori infection. However, knowledge of their worldwide and regional comparative efficacy is lacking. We examined the comparative effectiveness of all empirically used first-line regimens tested against standard triple treatment using a network meta-analysis of published randomized controlled trials. METHODS Data extracted from eligible randomized controlled trials were entered into a Bayesian network meta-analysis to investigate the comparative efficacy of H pylori infection empiric first-line regimens and to explore their effectiveness rank order. The ranking probability for each regimen was evaluated by means of surfaces under cumulative ranking values. RESULTS Sixty-eight eligible randomized controlled trials were included, giving a total of 92 paired comparisons with 22,975 patients randomized to 8 first-line regimens. The overall results showed that only vonoprazan triple therapy and reverse hybrid therapy achieved cure rates of >90%. Levofloxacin triple therapy performed best in Western countries (eradication rate 88.5%). The comparative effectiveness ranking showed that vonoprazan triple therapy had the best results, whereas standard triple therapy was the least efficacious regimen (surfaces under cumulative ranking 92.4% vs 4.7% respectively; odds ratio, 3.80; 95% credible interval, 1.62-8.94). CONCLUSIONS For first-line empiric treatment of H pylori infection, vonoprazan triple therapy and reverse hybrid therapy achieved high eradication rates of >90%. Levofloxacin triple therapy achieved the highest eradication rates in Western countries. Standard triple therapy was the least efficacious regimen in this network meta-analysis.

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
Recently in Korea, where triple therapy is accepted as the first-line Helicobacter pylori (H. pylori) eradication treatment, antibiotic resistance to clarithromycin has increased considerably, resulting in eradication rates of less than 80%. We investigated the efficacy of tailored therapy after a clarithromycin resistance test compared with empirical therapy for H. pylori eradication. The cost-effectiveness of H. pylori eradication success was evaluated according to the average medical cost per patient. A total of 364 patients were enrolled in the study. The first-line H. pylori eradication rate was significantly higher in patients who received tailored therapy than in those who received empirical therapy. The total medical costs for the tailored and empirical groups were 46,374 Won and 53,528 Won. The total treatment period for each ultimately successful eradication in the tailored group was 79.8 ± 2.8 days, which is shorter than that of the empirical group (99.2 ± 7.4 days). The rate of eradication-related adverse events for the tailored group and empirical group was 12.9% and 14.8%, respectively. Tailored therapy could be a useful option to achieve a higher successful eradication rate, shorter treatment periods, and lower medical costs than empirical therapy in the era of increasing antibiotic 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.

Abstract
Background/Aims: Standard triple therapy, including a proton pump inhibitor, clarithromycin, and amoxicillin, has been recommended as the first-line for <i>Helicobacter pylori</i> infection. However, the eradication rate of standard triple therapy has declined over the past years because of the increasing resistance to clarithromycin in Korea. We analyzed the eradication rates and the 10-year change in the eradication rates in Korea.Methods: PubMed, EMBASE, the Cochrane Library, and KoreaMed were searched for studies published between January 2007 and June 2018. The pooled eradication rates and their 95% CIs were estimated using a random-effect logistic regression model.Results: Twenty-six randomized controlled studies on standard triple therapy conducted in Korea were selected. The intention-to-treat (ITT) and per protocol analyses showed pooled eradication rates of standard triple therapy of 71.6% (95% CI, 69.9~73.3%) and 79.6% (95% CI, 76.6~82.2%), respectively. The eradication rate decreased with time. The ITT analysis showed that the 14-day therapy (78.1% [95% CI, 75.2~80.7%]) had significantly higher eradication rates than the 7-day therapy (70.0% [95% CI, 68.5~71.4%]) (<i>P</i><0.01).Conclusions: These results suggest that the eradication rate of standard triple therapy, as the first-line therapy, has shown an unacceptable decrease. The eradication rate increased when the duration of therapy was increased to 14 days, but it was not satisfactory. Therefore, other treatment regimens or therapies based on susceptibility tests should be considered for the first-line therapy.

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.

Comparison of four different regimens against Helicobacter pylori as a first-line treatment: A prospective, cross-sectional, comparative, open trial in Chinese children. Helicobacter 2020; 25:e12679. [PMID: 31958193 DOI: 10.1111/hel.12679] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 12/16/2019] [Accepted: 12/17/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUNDS Due to the decreasing eradication rate of Helicobacter pylori, some novel alternatives have been developed, such as bismuth-containing quadruple therapy and non-bismuth-containing quadruple therapy (sequential and concomitant treatment). Little is known about whether a success rate above 90% can be achieved with these regimens in Chinese children. METHODS In this prospective, open, comparative cross-sectional study, we recruited treatment-naïve children (aged between 6 and 18 years) with H pylori infection. The patients were assigned either standard triple therapy, sequential therapy, bismuth-based quadruple therapy, or concomitant therapy at the discretion of the prescribing physician. H pylori infection was evaluated at least 4 weeks after the completion of the treatment. A negative urea breath test (UBT) indicated successful eradication. The primary endpoint was the eradication frequency of H pylori in the full analysis set (FAS), which included all children who received at least one dose of the treatment and with available follow-up data. RESULTS Between September 2017 and December 2018, 228 patients were finally included in the FAS analyses. The eradication rates were 74.1% for standard triple therapy (43/58, [95% CI: 62.8%-85.5%]), 69.5% for sequential therapy (41/59, [95% CI: 57.8%-81.2%]), 89.8% for bismuth-based quadruple therapy (53/59, [95% CI: 82.1%-97.5%]), and 84.6% for concomitant therapy (44/52, [95% CI: 74.8%-94.4%]). Bismuth-based therapy was superior to triple therapy, while sequential therapy and concomitant therapy were not superior to triple therapy. The frequency of adverse events was 12.1% (7/58) in standard triple therapy, 6.8% (4/59) in sequential therapy, 15.3% (9/59) in bismuth-based therapy, and 15.4% (8/52) in concomitant therapy. The rate of adverse events was similar among the four groups. CONCLUSION Bismuth quadruple therapy can achieve an eradication rate of 89.8% as first-line treatment and is safe and well tolerated. Bismuth could be a promising alternative as a first-line regimen in Chinese children.

Abstract
BACKGROUND Although Helicobacter pylori is a key cause of gastric cancer development, its eradication rate has been decreasing by standard regimens. For successful eradication, duration of treatment has been issued for overcoming antibiotics resistance. We were to compare the eradication rate of 7-day vs. 14-day treatment in first- and second-line regimens. METHODS This study was an open-label randomized controlled trial. A total of 369 H. pylori-infected patients were enrolled and assigned either to 7-day or 14-day proton pump inhibitor (PPI)-based standard triple therapy (STT; PPI-clarithromycin-amoxicillin). Bismuth-containing quadruple therapy was used as second-line therapy. Eradication success was defined as a negative 13C-urea breath test. RESULTS In first-line treatment, eradication rate was 78.5% (106/135) and 78.6% (114/143) in the 7-day and 14-day treatment in per-protocol (PP) analysis (P = 0.805). In intention-to-treat (ITT) analysis, eradication rate was 64.0% (114/178) and 66.0% (126/191), respectively (P = 0.924). There was no significant difference in drug compliance (81.5% vs. 84.3%, P = 0.320). In second-line therapy, eradication rate was not significantly different in both treatments of PP analysis (91.7% [33/36] vs. 100% [45/45], P = 0.084). In the ITT analysis, eradication rate was 79.6% (35/44) and 90.4% (47/52), respectively (P = 0.080). Drug compliances were not significantly different between the two groups (95.5% vs. 98.1%, P = 0.728). CONCLUSION PPI-based STT for H. pylori is not efficient as a first-line therapy both in 7 days and 14 days in Korea. Although bismuth-containing quadruple therapy for 14 days as a second line therapy tend to show higher eradication rate compared to 7-day therapy, this should be elucidated by further larger scaled studies.

Abstract
Background/Aim. In Korea, the rate of Helicobacter pylori (H. pylori) eradication has declined steadily as a result of increasing resistance to antibiotics, especially dual resistance to clarithromycin and metronidazole. However, microbiological culture data on drug-resistant H. pylori is lacking. This study evaluated the antimicrobial efficacy of candidate antibiotics against resistant H. pylori strains. Methods. After retrospectively reviewing the data from the Helicobacter Registry in Gil Medical Center (GMC) and Asan Medical Center (AMC), along with 4 reference strains, we selected the 31 single- or multidrug-resistant strains. The susceptibility of the H. pylori strains to seven antibiotics (clarithromycin, metronidazole, levofloxacin, amoxicillin, tetracycline, rifabutin, and furazolidone) and minimum inhibitory concentration were tested using the broth microdilution technique. Results. Among 31 antibiotic resistance strains for H. pylori, there were no strains resistant to rifabutin or furazolidone, which had MICs of <0.008 and 0.5 μg/mL, respectively. Only one tetracycline-resistant strain was found (MIC < 2 μg/mL). Amoxicillin and levofloxacin were relatively less effective against the H. pylori strains compared to rifabutin or furazolidone (resistance rates 22.6%, 1.9%, respectively). Tetracycline showed the relatively low resistance rates (3.2%) for H. pylori strains. Conclusions. Therefore, along with tetracycline which has already been used as a component for second-line eradication regimen for Helicobacter, rifabutin and furazolidone, alone or in combination, could be used to eradicate antibiotic-resistant H. pylori strains where drug-resistant Helicobacter spp. are increasing.

Abstract
BACKGROUND The eradication rate of Helicobacter pylori has declined, mainly due to antimicrobial resistance. To overcome resistance-associated treatment failure, the efficacy of culture-based, susceptibility-guided therapy was demonstrated as the first-line eradication therapy for H pylori infection. AIMS To evaluate the efficacy of culture-based therapy as the first-line eradication therapy in regions with high levels of antimicrobial resistance. METHODS Helicobacter pylori-positive patients without previous eradication treatment history were recommended to undergo culture to determine the minimal inhibitory concentration (MIC). If they consented, 7-day clarithromycin-containing PPI triple; 7-day esomeprazole, moxifloxacin, and amoxicillin (MEA) therapy; or 7- or 14-day esomeprazole, bismuth, metronidazole, and tetracycline (quadruple) therapy were administered based on the agar dilution-determined MIC. Eradication, treatment compliance, and adverse events were examined. RESULTS In total, 74 patients were enrolled, and 69 patients completed the protocols. The overall resistance rates to amoxicillin, clarithromycin, metronidazole, and moxifloxacin were 6.7%, 31.0%, 41.8%, and 39.2%, respectively. The patients were allocated to the PPI triple (n = 50), MEA (n = 8) or quadruple (n = 16) therapy. The eradication rate in the intention-to-treat analysis was 93.1% (69 of 74 patients). The eradication rates in the per-protocol analysis were 100.0% (69 of 69 patients). Epigastric pain, nausea, and vomiting were less common than those of other empirical therapies. CONCLUSIONS Culture-based, susceptibility-guided therapy is effective first-line eradication therapy, especially in regions with high levels of antimicrobial resistance.

Abstract
Background Most international guidelines recommend triple-therapy regimens consisting of a proton pump inhibitor, clarithromycin, and amoxicillin/metronidazole for at least 7 days for the eradication of Helicobacter pylori. However, the efficacy of 7-day clarithromycin-based standard triple therapy for H. pylori infection is currently unacceptable in Korea. In this study, we will compare the efficacy and safety of 7-day standard triple therapy, 10-day sequential therapy, and 10-day concomitant therapy for the first-line treatment of H. pylori infection in Korea. Methods/design In this multicenter, investigator-blinded, randomized trial we are recruiting adult patients with H. pylori infection from 15 hospitals in Korea to determine whether sequential or concomitant treatment is superior to standard triple therapy. Patients are randomly assigned to receive either standard triple therapy (lansoprazole, amoxicillin, and clarithromycin) for 7 days, or sequential treatment (lansoprazole and amoxicillin for the first 5 days, followed by lansoprazole, clarithromycin, and metronidazole for another 5 days) for 10 days, or concomitant therapy (lansoprazole, amoxicillin, clarithromycin, and metronidazole) for 10 days. The primary outcome is the rate of H. pylori eradication in the intention-to-treat population. Discussion The results of this study will be crucial for determining the optimal regimen for the primary treatment of H. pylori infection in Korea. This study will produce vital evidence that will lead to revisions to guidelines concerning first-line treatment regimens for H. pylori infection.

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

Abstract
BACKGROUND The efficacy of Helicobacter pylori eradication regimens may depend on the country where the studies were performed because of the difference in antibiotic resistance. We aimed to analyze the efficacy of H. pylori eradication regimens in Korea where clarithromycin resistance rate is high. METHODS We searched for all relevant randomized controlled trials published until November 2016 that investigated the efficacy of H. pylori eradication therapies in Korea. A network meta-analysis was performed to calculate the direct and indirect estimates of efficacy among the eradication regimens. RESULTS Forty-three studies were identified through a systematic review, of which 34 studies, published since 2005, were included in the meta-analysis. Among 21 included regimens, quinolone-containing sequential therapy for 14 days (ST-Q-14) showed the highest eradication rate (91.4% [95% confidence interval [CI], 86.9%-94.4%] in the intention-to-treat [ITT] analysis). The eradication rate of the conventional triple therapy for 7 days, standard sequential therapy for 10 days, hybrid therapy for 10-14 days, and concomitant therapy for 10-14 days was 71.1% (95% CI, 68.3%-73.7%), 76.2% (95% CI, 72.8%-79.3%), 79.4% (95% CI, 75.5%-82.8%), and 78.3% (95% CI, 75.3%-80.9%), respectively, in the ITT analysis. In the network meta-analysis, ST-Q-14 showed a better comparative efficacy than the conventional triple therapy, standard sequential therapy, hybrid therapy, and concomitant therapy. In addition, tolerability of ST-Q-14 was comparable to those regimens. CONCLUSION In Korea, ST-Q-14 showed the highest efficacy in terms of eradication and a comparable tolerability, compared to the results reported for the conventional triple therapy, standard sequential therapy, hybrid therapy, and concomitant therapy.

Abstract
Because the prevalence of antibiotic resistance markedly increases with time worldwide, anti-H. pylori treatment is continuing to be a great challenge forsphysicians in clinical practice. The Real-world Practice & Expectation of Asia-Pacific Physicians and Patients in Helicobacter Pylori Eradication (REAP-HP) Survey demonstrated that the accepted minimal eradication rate of anti-H. pylori regimen in H. pylori-infected patients was 91%. The Kyoto Consensus Report on Helicobacter Pylori Gastritis also recommended that, within any region, only regimens which reliably produce eradication rates of ≥90% in that population should be used for empirical treatment. This article is aimed to review current first-line eradication regimens with a per-protocol eradication rate exceeding 90% in most geographic areas. In regions with low (≦15%) clarithromycin resistance, 14-day hybrid (or reverse hybrid), 10 ~ 14-day sequential, 7 ~ 14-day concomitant, 10 ~ 14-day bismuth quadruple or 14-day triple therapy can achieve a high eradication rate in the first-line treatment of H. pylori infection. However, in areas with high (>15%) clarithromycin resistance, standard triple therapy should be abandoned because of low eradication efficacy, and 14-day hybrid (or reverse hybrid), 10 ~ 14-day concomitant or 10 ~ 14-day bismuth quadruple therapy are the recommended regimens. If no recent data of local antibiotic resistances of H. pylori strains are available, universal high efficacy regimens such as 14-day hybrid (or reverse hybrid), concomitant or bismuth quadruple therapy can be adopted to meet the recommendation of consensus report and patients’ expectation.

Abstract
OBJECTIVE The aims of the study were: 1, to survey the most popular anti-H. pylori regimens in Asia-Pacific region and the real-world effectiveness of these regimens; and 2, to investigate the expectation gaps of eradication rate between physicians and patients. DESIGN A questionnaire was distributed to Asia-Pacific physicians who attended the Asia-Pacific Digestive Week 2015 meeting. Reported eradication rates from the literatures were compared with real-world rates of surveyed popular regimens within the region. In addition, a questionnaire was distributed to H. pylori-infected patients in three regions of Taiwan. RESULTS A total of 691 physicians and 539 patients participated in the survey. The top five most commonly used regimens were 7-day clarithromycin-based standard triple therapy (50.4%), 14-day clarithromycin-based standard triple therapy (31.0%), 10-day sequential therapy (6.1%), 14-day bismuth quadruple therapy (3.9%), and 14-day hybrid therapy (3.6%). All countries except for China had a significant gap between the expectation of physicians on anti-H. pylori therapy and the real-world eradication rate of most commonly adopted regimens (all P value <.05). The expectation on minimal eradication rate among patients was higher than that of physicians (91.4% vs 86.5%, P<.001). CONCLUSIONS It is time for physicians in Asia-Pacific countries to adopt newer and more efficacious anti-H. pylori regimens to meet the Kyoto consensus recommendation and their patients' expectations.

BMC Gastroenterol 2017; 17:27. [PMID: 28193167 PMCID: PMC5307850 DOI: 10.1186/s12876-017-0588-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Accepted: 02/10/2017] [Indexed: 12/14/2022] Open
Abstract
Background Helicobacter pylori (HP) infection is present in about 50% of the global population, and is associated with chronic gastritis, peptic disease and gastric malignancies. HP prevalence in Crohn’s disease (CD) patients was shown to be low compared to the general population, and its influence on disease activity is yet to be determined. Our aims were to determine the prevalence of HP in a selected group of CD patients with quiescent disease, and to assess the influence of its eradication on disease activity and endoscopic and laboratory activity measures. Methods Consecutive CD patients with quiescent disease underwent meticulous disease evaluation with MR enterography (MRE), video capsule endoscopy (VCE), CRP, fecal calprotectin and CDAI. All patients were tested for the presence of HP using stool antigen detection kit. Patients infected with HP were offered eradication treatment with sequential therapy. HP eradication was confirmed using urease breath test and stool antigen test. The influence of HP eradication on disease activity was assessed. Results Out of 56 patients enrolled, six patients (10.7%) had HP infection. Of them, five patients had gastro- duodenitis per VCE. All HP positive patients were offered eradication treatment and underwent successful eradication. Notably, 23 (50%) of patients had proximal disease per VCE, most of them (78%) were HP negative. CDAI, CRP, fecal calprotectin and VCE Lewis inflammatory score did not change significantly following HP eradication, Gastric findings on VCE were not impacted by HP eradication. Conclusions The prevalence of HP infection in patients with quiescent CD is relatively low. Eradication of the bacteria did not significantly change neither disease activity measures nor the presence of gastro- duodenitis per VCE, suggesting it might be part of proximal CD. The influence of HP on CD activity merits further investigation.

Optimal First-Line Treatment for Helicobacter pylori Infection: Recent Strategies. Gastroenterol Res Pract 2016; 2016:9086581.

Abstract
A new treatment strategy is needed, as the efficacy of triple therapy containing clarithromycin—the current standard treatment for Helicobacter pylori infection—is declining. Increasing antibiotic resistance of H. pylori is the most significant factor contributing to eradication failure. Thus, selecting the most appropriate regimen depending on resistance is optimal, but identifying resistance to specific antibiotics is clinically challenging. In a region suspected to have high clarithromycin resistance, bismuth quadruple therapy and so-called nonbismuth quadruple therapies (sequential, concomitant, and sequential-concomitant hybrid) are some first-line regimen options. However, more research is needed regarding appropriate second-line treatments after first-line treatment failure. Tailored therapy, which is based on antibiotic sensitivity testing, would be optimal but has several limitations for clinical use, and an alternative technique is required. A novel potassium-competitive acid blocker-based eradication regimen could be a valuable eradication option in the near future.

Abstract
Helicobacter pylori (H. pylori) is a kind of gram-negative anaerobic bacterium that was first successfully isolated and cultivated from the specimens of the gastric mucosa by Warren and Marshall in 1983. It is one of the risk factors for gastric cancer and is closely related with chronic gastritis, peptic ulcer, gastric cancer and other diseases of the digestive system. There are a variety of detection technologies and diagnostic methods available for H. pylori infection, including direct detection of the bacterium, urease detection, antigen and antibody detection, polymerase chain reaction and so on. Generally, these methods can be divided into two major categories: invasive and non-invasive. However, no single test can be considered the gold standard for the diagnosis of H. pylori infection. In this paper, we will summarize a kind of completely non-invasive detection method - detection of H. pylori antibody in urine, review its use in the diagnosis of ongoing infection, and discuss its value in clinical applications.
