Lee CT, Wu CT, Chang WL, Yang EH, Hsieh MT, Chen WY, Sheu BS, Cheng HC. 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.

Zou SP, Cheng Q, Feng CY, Xu C, Sun MH. Comparative effectiveness of first-line therapies for eradication of antibiotic-resistant Helicobacter pylori strains: A network meta-analysis. 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.

Ten-day concomitant and sequential therapy for Helicobacter pylori effective in region with high antibiotic resistance rates. Indian J Gastroenterol 2022; 41:627-633. [PMID: 36573961 DOI: 10.1007/s12664-022-01272-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 06/07/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Increasing antibiotic-resistant Helicobacter pylori (H. pylori) strains complicate efforts to eradicate infection. In regions with high dual resistance to both clarithromycin and metronidazole, bismuth quadruple therapy is recommended. But, with lack of easy availability of bismuth, the (non-bismuth) concomitant and sequential regimens are used commonly as first-line therapy. Recent reports indicate suboptimal results with sequential therapy in such regions. We aimed to compare the efficacy of concomitant therapy vs. sequential therapy in the eradication of H. pylori in a region with high antibiotic resistance rates, and to compare adherence rates and adverse events with the regimens. METHODS One hundred and twenty-four consecutive H. pylori-infected patients (diagnosed using rapid urease test or urea breath test) were randomized to receive sequential or concomitant therapy for 10 days each. Four weeks after treatment completion, urea breath test was done to confirm eradication of the infection. Cure rates were compared between the two regimens and note was made of adherence rates and adverse events. RESULTS Concomitant therapy showed a statistically non-significant higher cure rate compared to sequential therapy in intention-to-treat (87.1% vs. 81.4%%, p = 0.46) and per-protocol (94.7% vs. 83.9%, p = 0.07) analyses. Both the regimens were well tolerated and showed similar adherence rates (p = 1.00) and incidence of adverse events (p = 0.44). CONCLUSION In a region with high dual resistance, both concomitant and sequential therapy for H. pylori infection achieved eradication rates >80%, but concomitant therapy showed a statistically non-significant higher cure rate, with similar adherence and adverse event profiles.

Abstract
BACKGROUND Increasing clarithromycin resistance has led to changes in several guidelines for treatment of Helicobacter pylori infections. We compared the H. pylori eradication rates of the empirical concomitant therapy (CoT) and a tailored therapy (TaT) using dual-priming oligonucleotide-based polymerase chain reaction to detect mutations in the 23S rRNA gene that are related to clarithromycin resistance. METHODS Between June 2020 and May 2021, 290 patients were enrolled and randomly assigned to 2 groups. In the CoT group, the patients received rabeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg twice daily for 14 days. In the TaT group, point mutation-negative patients received rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg twice daily for 14 days and point mutation-positive patients received rabeprazole 20 mg twice daily, metronidazole 500 mg thrice daily, and bismuth 120 mg and tetracycline 500 mg 4 times daily for 14 days. RESULTS A total of 290 and 261 patients were included in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively. A2142G and/or A2143G point mutations were identified in 28.6% of the patients. No significant difference in eradication rates were observed between the 2 groups as per ITT (CoT, 82.8% and TaT, 85.5%, P = .520) and PP (CoT, 88.6% and TaT, 94.6%, P = .084) analyses. In point mutation-positive patients, the eradication rates in the CoT group were lower than those in the TaT group as per ITT (69.8% and 87.5%, respectively, P = .050) and PP (76.9% and 97.1%, respectively, P = .011) analyses. CONCLUSION CoT and TaT showed similar overall eradication rates for H. pylori. However, CoT eradication rate was suboptimal, especially in point mutation-positive patients.

Abstract
Sequential therapy (ST) and concomitant therapy (CT) are common first-line treatments for Helicobacter pylori (HP). This study aimed to assess the efficiency and safety of ST and CT in the first-line treatment of HP by comparing their clinical outcomes. Two authors independently searched PubMed, EBSCO, Web of Science and the Cochrane Library for all the relevant articles published before March 2021 to compare the clinical outcomes of HP patients undergoing ST or CT. The primary outcome measures were HP eradication rates and adverse events (AEs). This meta-analysis included 24 articles with 7531 HP patients. CT was better than ST in eradicating HP from per-protocol analysis (PP) (RR=0.96, P<0.001) and modified intent-to-treat analysis (MITT) (RR=0.94, P=0.005). Compared with non-Asia, CT demonstrated more apparent advantages than ST in Asia. CT treated with lansoprazole, pantoprazole and esomeprazole outperformed ST treated with the same PPIs. CT for 10 days and ST for 14 days were the better choices of course of treatment. The incidence rates of AEs were significantly higher in CT than in ST for diarrhoea (RR=0.65, P<0.001), vomiting (RR=0.68, P=0.03), dysgeusia (RR=0.83, P=0.03) and dizziness (RR=0.77, P=0.05). Both ST and CT are safe and effective first-line treatments for HP. Although the AEs were more frequent with CT than ST, CT was superior to ST, especially in Asia. The effect of various PPIs varied in various therapies. The best course of treatment was 10 days for CT and 14 days for ST.

Abstract
BACKGROUND The prevalence of Helicobacter pylori (H. pylori) in developing countries is 50.8%, with the highest occurrence presented in Africa (79.1%). It increases the risk of chronic gastritis, peptic ulcer, cancer of the stomach, and lymphoma. The effect of standard treatment for H. pylori eradication is below 80%, and evaluation of alternative lines of treatment is needed. We aimed to compare the hybrid, reverse hybrid, and levofloxacin quadruple therapies as first-line therapy in Egypt. METHODS This was a randomized interventional trial done in the clinics affiliated with the Internal Medicine Department. 330 individuals were selected according to the inclusion criteria. They were divided into three groups: group 1 (110 subjects who received a reverse hybrid regimen), group 2 (110 subjects who received a hybrid regimen), and group 3 (110 subjects who received a non-bismuth levofloxacin quadruple regimen). RESULTS Group 3 had a significantly lower eradication rate of 82.7% versus 92.7% and 91.8% in groups 1 and 2, respectively. There were non-significant differences in the incidence rates of adverse events among the three groups. CONCLUSION Both the reverse hybrid and hybrid groups had good eradication rates in the Egyptian population, but non-bismuth levofloxacin quadruple therapy did not obtain a sufficient eradication rate.

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 (H. pylori) infection is associated with the development of multiple diseases. The eradication rate of H. pylori has gradually decreased, suggesting the need to discover more effective therapies. This study aimed to compare the effectiveness of first-line treatments including high-dose dual therapy (HDDT), bismuth-based quadruple therapy (BQT), sequential therapy (ST), concomitant therapy (CT) and hybrid therapy (HT) by network meta-analysis (NMA). A comprehensive search on PubMed, Embase, Cochrane Library and Web of Science, was performed from their inception to 1 September 2019. A network analysis of randomized controlled trials (RCTs) comparing first-line therapies were carried out using Stata 14.0 and Revman 5.2. Moreover, a sensitivity analysis was conducted by omitting non-Asian studies. Finally, 41 RCTs with 14 119 patients were included. The NMA showed that, in terms of eradication rate, ST for 10 days (ST-10) was significantly lower than CT for 10 or 14 days (CT ≥ 10). Sensitivity analysis among the Asian population showed that ST-10 denoted the lowest effectiveness among the interventions. The ranking results based on probability showed that HDDT ranked first for the eradication rate. As for adverse events, HDDT was significantly less than BQT and CT regardless of duration, while BQT for 14 days represented higher adverse events than ST, HT and CT ≥ 10. HDDT ranked first among the therapies. In conclusion, HDDT for 14 days appeared to be the most optimal first-line therapy for H. pylori among the Asian population with comparable efficacy and compliance but causing fewer adverse events.

Abstract
BACKGROUND Addressing the increasing antibiotic resistance, including clarithromycin resistance, which affects Helicobacter pylori eradication therapy, is a challenge for clinicians. The objective of this study was to determine the efficacy of bismuth added to standard triple therapy as a first-line treatment regimen for Helicobacter pylori infection. The secondary outcome was the treatment efficacy for clarithromycin-resistant strains. MATERIAL AND METHODS A prospective study was undertaken from January to December 2019. A total of 107 patients with Helicobacter pylori infection were enrolled and received Helicobacter pylori eradication therapy with bismuth added to standard triple therapy for 14 days. We also evaluated the clarithromycin resistance rate by dual-priming oligonucleotide-based multiplex PCR and treatment efficacy. RESULTS A total of 104 patients completed standard triple therapy with bismuth added for Helicobacter pylori eradication. The eradication rates in the intention to treat and per-protocol analyses were 87.9% and 90.4%, respectively. The frequency of clarithromycin resistance was 33.6% (35/104), and the eradication rate was 77.1% in resistant strains (27/35). CONCLUSION Bismuth added to standard triple therapy could be acceptable as a first-line treatment regimen for Helicobacter pylori eradication in patients with clarithromycin-resistant strains. In particular, in areas with high clarithromycin tolerance, it is advisable to consider bismuth add-on therapy as the first-line treatment regimen.

Consistency of Helicobacter pylori eradication rates of first-line concomitant and sequential therapies in Korea: A nationwide multicenter retrospective study for the last 10 years. Helicobacter 2021; 26:e12780. [PMID: 33596342 DOI: 10.1111/hel.12780] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 11/19/2020] [Accepted: 12/13/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Eradication rate of standard triple therapy for H. pylori has declined to unacceptable level, and alternative regimens such as concomitant and sequential therapy have been introduced. We aimed to assess the consistency of eradication rates of concomitant and sequential therapies as for the first-line H. pylori eradication in Korea. METHODS A nationwide multicenter retrospective study was conducted including 18 medical centers from January 2008 to December 2017. We included 3,800 adults who had test to confirm H. pylori eradication within 1 year after concomitant or sequential therapy. RESULTS Concomitant and sequential therapy were prescribed for 2508 and 1292 patients, respectively. The overall eradication rate of concomitant therapy was significantly higher than that of sequential therapy (91.8% vs. 86.1%, p < .001). In time trend analysis, the eradication rates of concomitant therapy were 90.2%, 88.2%, 92.1%, 94.3%, 91.1%, and 93.4% for each year from 2012 to 2017 with an increasing trend (p = .0146), while those of ST showed no significant trend (p = .0873). Among 263 patients with second-line therapy, bismuth quadruple therapy showed significantly higher eradication rate than quinolone-based triple therapy (73.9% vs. 51.5% in ITT analysis, p = .001; 82.7% vs. 63.0% in PP analysis, p = .002). CONCLUSION Concomitant therapy is the best regimen for the first-line H. pylori eradication showing consistently higher eradication rate with an increasing trend for the last 10 years in Korea. Bismuth quadruple therapy should be considered for second-line therapy after eradication failure using non-bismuth quadruple therapy.

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
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.

Gastroenterology 2018; 155:1372-1382.e17. [PMID: 29990487 PMCID: PMC6905086 DOI: 10.1053/j.gastro.2018.07.007] [Citation(s) in RCA: 669] [Impact Index Per Article: 111.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2018] [Revised: 06/27/2018] [Accepted: 07/05/2018] [Indexed: 02/06/2023]
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.

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 The efficacy of the standard triple therapy for Helicobacter pylori eradication has decreased to an unacceptable level. We aimed to compare the efficacy of sequential and concomitant therapies as for the first-line treatments for H. pylori eradication and analyzed the effect of clarithromycin resistance on the eradication rates. MATERIALS AND METHODS Four hundred and seventy-eight patients with H. pylori infection were randomly assigned to either concomitant therapy (amoxicillin 1000 mg with clarithromycin 500 mg, metronidazole 500 mg, and pantoprazole 40 mg twice daily for 10 days) or sequential therapy (amoxicillin 1000 mg with pantoprazole 40 mg twice daily for 5 days, followed by clarithromycin 500 mg with metronidazole 500 mg and pantoprazole 40 mg twice daily for 5 days). The success of the eradication was evaluated 4-5 weeks after treatment completion. To evaluate the efficacy of the two regimens according to clarithromycin sensitivity, dual-priming oligonucleotide-based multiplex-polymerase chain reaction was also performed in the final third of the enrolled study populations. RESULTS The eradication rates with concomitant or sequential therapy were 81.9% and 76.6% (P = .153) in intention-to-treat analysis, and 93.4% and 84.8% (P = .004) in per-protocol analysis, respectively. Among the 156 patients for whom dual-priming oligonucleotide-based multiplex-polymerase chain reaction was performed, 17.9% were clarithromycin resistant, and the efficacy of concomitant therapy was better than sequential therapy in the clarithromycin-resistant strains (100% vs 58.3%, P = .010). CONCLUSION Concomitant therapy was superior to sequential therapy as the first-line treatment for H. pylori eradication, especially in clarithromycin-resistant strains in Korea.

Abstract
Background/Aims Hybrid therapy was successful in eradicating Helicobacter pylori (H. pylori) according to previous reports. However, to the best of our knowledge, there have only been a few studies evaluating the optimal choice after hybrid failure. Hence, we aimed to evaluate the efficacy of moxifloxacin-containing triple therapy after hybrid therapy failure in H. pylori eradication. Methods Between January 2013 and March 2016, we retrospectively reviewed patients who underwent failed hybrid therapy, as first line treatment, in eradicating H. pylori (rabeprazole and amoxicillin b.i.d for 14 days, in addition to clarithromycin and metronidazole b.i.d for final 7 days). Then, we investigated the eradication rates of moxifloxacin-containing triple therapy (rabeprazole, amoxicillin b.i.d and moxifloxacin qd) as the second line of treatment. Intention-to-treat (ITT) and per-protocol (PP) analyses were used to determine the eradication rate. We evaluated the status of H. pylori by using 13C-urea breath test 6 weeks after the final treatment. Moreover, compliance and adverse effects of each patient were analyzed. Results Among those who failed the initial hybrid therapy, 11 patients received moxifloxacin-containing triple therapy. The overall eradication rates, as determined by ITT and PP, were 72.7% (n=8/11) and 80% (n=8/10), respectively. The compliance rate was 100%, and there were no serious adverse effects. Conclusions Moxifloxacin-containing triple therapy can be used as a second line therapy in case of hybrid therapy failure. A large scale study is necessary to confirm the findings of this study and establish clinical evidence.

Adding Bismuth to Rabeprazole-Based First-Line Triple Therapy Does Not Improve the Eradication of Helicobacter pylori. Gastroenterol Res Pract 2017; 2017:5320180. [PMID: 28791044 PMCID: PMC5534286 DOI: 10.1155/2017/5320180] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2017] [Accepted: 06/11/2017] [Indexed: 12/31/2022] Open
Abstract
This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori. A total of 162 patients with Helicobacter pylori infection were randomly assigned to either the 7-day triple therapy group (RAK regimen: rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg bid; n = 81) or the bismuth plus triple therapy group (n = 81). In the RBAK group, bismuth subcitrate 360 mg twice daily was added to the RAK regimen. A follow-up endoscopy or urea breath test was performed at least 4 weeks after eradication to confirm the treatment efficacy. Comparable compliance and Helicobacter pylori eradication rates were observed in both groups in either intention-to-treat [RAK 72.8% (59/81) versus RBAK 77.8% (63/81); p = 0.47] or per protocol analysis [RAK 74.7% (59/79) versus RBAK 81.8% (63/77); p = 0.26]. Adverse effects were commonly reported (50.6% for both groups) although most of these did not cause cessation of treatment. The resistance rate was 27.2% for metronidazole and 12.3% for clarithromycin. Adding bismuth to the standard 7-day triple therapy did not substantially increase the eradication rate. Further study is needed clarifying whether extending the duration of RBAK regimen to 10–14 days can lead to a better result.

Abstract
BACKGROUND AND AIM Whether concomitant therapy is superior to sequential therapy (ST) as first-line therapy of Helicobacter pylori in areas with high clarithromycin resistance remains controversial. The aim of this study was to compare the efficacy and tolerability of 10- or 14-day ST with 10- or 14-day concomitant therapy (CT). METHODS This was a prospective randomized study comparing 10- or 14-day ST with 10- or 14-day CT. The ST-10 and ST-14 groups received pantoprazole 40 mg and amoxicillin 1 g twice a day for the first 5 and 7 days followed by pantoprazole 40 mg, clarithromycin 500 mg, and metronidazole 500 mg twice a day for the remaining 5 and 7 days, respectively. The CT-10 and CT-14 groups received pantoprazole 40 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg twice daily for 10 and 14 days, respectively. RESULTS Three hundred forty-one patients were randomly allocated to the four groups. The modified intention-to-treat eradication rates of ST-10, ST-14, CT-10, and CT-14 were 91.7%, 91.2%, 94.2%, and 98.5%, respectively. The corresponding per protocol eradication rates were 91.4%, 91.0%, 95.6%, and 98.5%. There was no difference in compliance and adverse events in the four groups. Eradication rates increased sequentially with statistical significance in the following order: ST-10, ST-14, CT-10, and CT-14 (P = 0.044). CONCLUSIONS All four regimens achieved eradication rates >90% in per protocol analyses in a country with high clarithromycin resistance. There was no difference in tolerability among the four regimens.

Abstract
Objective: To compare the sequential therapy (ST) with the hybrid therapy (HT) for the eradication of Helicobacter pylori. Materials and Methods: Patients with peptic ulcer disease and gastritis found to be H. pylori positive were randomized to HT group who received omeprazole (20 mg bid) and amoxicillin (1 g bid) for 7 days followed by omeprazole (20 mg bid), amoxicillin (1 g bid), clarithromycin (500 mg bid), and metronidazole (400 mg tid) for the next 7 days and ST group who received omeprazole and amoxicillin for 5 days followed by omeprazole, clarithromycin, and metronidazole for the next 5 days. Eradication rate, compliance, and complications were compared. Results: A total of 120 patients were included, sixty in each group. H. pylori eradication rate was significantly higher in HT group on intention-to-treat analysis (88.3% [confidence interval (CI) 78.3%–94.8%] vs. 73.3% [CI 61.1%–83.3%]; P = 0.037). Per-protocol analysis showed higher eradication rate with HT (93% [CI 83.9%–93.7%] vs. 81.5% [CI 69.5%–90.2%]; P = 0.068); however, the difference was insignificant. Compliance and side effects were similar. A complete course of HT costs $10.77, while ST costs only $6.347. Conclusions: HT achieves significantly higher H. pylori eradication rate than ST with comparable patient compliance and side effects but at an higher price. However, it can be used in places where ST is ineffective.

Abstract
OBJECTIVE The objective of this study is to compare, in Greece, a region with >20% local resistance to clarithromycin, the efficacy rates of the concomitant versus the sequential H. pylori eradication therapy. MATERIALS AND METHODS Our prospective randomized study included 364 patients with newly diagnosed H. pylori infection, randomized to receive a 10-day concomitant or 10-day sequential therapy. Treatment outcome was assessed by C(13)-urea breath test at least 4 weeks after therapy. Intention to treat (ITT) and per protocol (PP) analysis of the eradication rates were performed. Secondary end points included patient compliance and safety. RESULTS The concomitant therapy group achieved statistically significant higher eradication rates when compared with the sequential treatment group, both in the ITT and in the PP analysis (84.6% versus 70.9%, p = 0.002, and 90.6% versus 78.1%, p = 0.001, respectively), after adjusting for age, gender, smoking status, and the presence or not of ulcer and/or non-ulcer dyspepsia. Both groups displayed excellent compliance rates (99.5% for the concomitant therapy group and 96.2% for the sequential therapy group, p = 0.067). Regarding treatment safety, major adverse events that led to the discontinuation of both regimens were few, with no statistical difference between the two groups (7.0% for the concomitant therapy group and 2.9% for the sequential therapy group). CONCLUSIONS Concomitant therapy led to statistically significant higher eradication rates over sequential therapy. Both therapies showed excellent compliance and an acceptable safety profile. The 10-day quadruple concomitant scheme should be the adopted for first-line H. pylori eradication in Greece.

Abstract
BACKGROUND Currently only a few studies compare sequential and concomitant non-bismuth Helicobacter pylori therapies referring to high antibiotic resistance populations. MATERIALS AND METHODS This multicenter prospective randomized clinical trial included 353 H. pylori positive, treatment naïve, patients. All patients had positive CLO-test and/or histology and culture. They received sequential (esomeprazole 40mg, amoxicillin 1g/bid for 5days, followed by 5days of esomeprazole 40mg, clarithromycin 500mg and metronidazole 500mg bid), or concomitant treatment (all drugs taken concomitantly bid for 10days). Eradication was confirmed by (13)C-urea breath test or histology 4-6weeks after treatment. Adverse events and adherence were evaluated. RESULTS Allocated to concomitant were 175 (72F/103M, mean 52.3years, 38.3% smokers, 25.7% ulcer disease) and 178 (87F/91M, mean 52years, 31% smokers, 19.1% ulcer disease) patients to sequential treatment. There were 303/353 (85.8%) positive cultures, with the following resistances: 34% metronidazole, 27.7% clarithromycin, and 7.9% dual. Eradication rates were, respectively, 89.1% (156/175) vs. 78.7% (140/178) by intention to treat (p=0.01, 95% CI=2.7-18) and 93.4%(156/167) vs. 82.8% (140/169) per protocol (p=0.004, 95% CI=3.6-17.6). Overall, adherence was (98.9%, 95% CI=97-100). Eradication rates according to resistance were the following: dual susceptible strains 67/69 (97.1%), 62/67 (92%) (p=0.4), metronidazole single resistant 38/39 (97.4%), 31/39 (79.5%) (p=0.03, 95% CI=3.5-33), clarithromycin single resistant 25/28 (89.3%), 26/31 (83.9%) (p=0.8), and dual resistant 9/12 (75%), 4/11 (36.4%) (p=0.1) for concomitant and sequential regimens, respectively. Side effects were comparable among regimens, except from diarrhea being more frequent among patients treated with concomitant treatment. CONCLUSIONS Concomitant treatment eradication rate overcomes 90% per protocol and has a significant advantage over sequential therapy. This is probably due to its better efficacy on metronidazole resistant strains. Both regimens were well tolerated and safe.

Abstract
BACKGROUND Non-bismuth quadruple sequential therapy (SEQ) comprising a first induction phase with a dual regimen of amoxicillin and a proton pump inhibitor (PPI) for five days followed by a triple regimen phase with a PPI, clarithromycin and metronidazole for another five days, has been suggested as a new first-line treatment option to replace the standard triple therapy (STT) comprising a proton pump inhibitor (PPI), clarithromycin and amoxicillin, in which eradication proportions have declined to disappointing levels. OBJECTIVES To conduct a meta-analysis of randomised controlled trials (RCTs) comparing the efficacy of a SEQ regimen with STT for the eradication of H. pylori infection, and to compare the incidence of adverse effects associated with both STT and SEQ H. pylori eradication therapies. SEARCH METHODS We conducted bibliographical searches in electronic databases, and handsearched abstracts from Congresses up to April 2015. SELECTION CRITERIA We sought randomised controlled trials (RCTs) comparing 10-day SEQ and STT (of at least seven days) for the eradication of H. pylori. Participants were adults and children diagnosed as positive for H. pylori infection and naïve to H. pylori treatment. DATA COLLECTION AND ANALYSIS We used a pre-piloted, tabular summary to collect demographic and medical information of included study participants as well as therapeutic data and information related to the diagnosis and confirmatory tests.We evaluated the difference in intention-to-treat eradication between SEQ and STT regimens across studies, and assessed sources of the heterogeneity of this risk difference (RD) using subgroup analyses.We evaluated the quality of the evidence following Cochrane standards, and summarised it using GRADE methodology. MAIN RESULTS We included 44 RCTs with a total of 12,284 participants (6042 in SEQ and 6242 in STT). The overall analysis showed that SEQ was significantly more effective than STT (82% vs 75% in the intention-to-treat analysis; RD 0.09, 95% confidence interval (CI) 0.06 to 0.11; P < 0.001, moderate-quality evidence). Results were highly heterogeneous (I² = 75%), and 20 studies did not demonstrate differences between therapies.Reporting by geographic region (RD 0.09, 95% CI 0.06 to 0.12; studies = 44; I² = 75%, based on low-quality evidence) showed that differences between SEQ and STT were greater in Europe (RD 0.16, 95% CI 0.14 to 0.19) when compared to Asia, Africa or South America. European studies also showed a tendency towards better efficacy with SEQ; however, this tendency was reversed in 33% of the Asian studies. Africa reported the closest risk difference (RD 0.14 , 95% 0.07 to 0.22) to Europe among studied regions, but confidence intervals were wider and therefore the quality of the evidence showing SEQ to be superior to STT was reduced for this region.Based on high-quality evidence, subgroup analyses showed that SEQ and STT therapies were equivalent when STT lasted for 14 days. Although, overall, the mean eradication proportion with SEQ was over 80%, we noted a tendency towards a lower average effect with this regimen in the more recent studies (2008 and after); weighted linear regression showed that the efficacies of both regimens evolved differently over the years, having a higher reduction in the efficacy of SEQ (-1.72% yearly) than in STT (-0.9% yearly). In these more recent studies (2008 and after) we were also unable to detect the superiority of SEQ over STT when STT was given for 10 days.Based on very low-quality evidence, subgroup analyses on antibiotic resistance showed that the widest difference in efficacy between SEQ and STT was in the subgroup analysis based on clarithromycin-resistant participants, in which SEQ reached a 75% average efficacy versus 43% with STT.Reporting on adverse events (AEs) (RD 0.00, 95% CI -0.02 to 0.02; participants = 8103; studies = 27; I² = 26%, based on high-quality evidence) showed no significant differences between SEQ and STT (20.4% vs 19.5%, respectively) and results were homogeneous.The quality of the studies was limited due to a lack of systematic reporting of the factors affecting risk of bias. Although randomisation was reported, its methodology (e.g. algorithms, number of blocks) was not specified in several studies. Additionally, the other 'Risk of bias' domains (such as allocation concealment of the sequence randomisation, or blinding during either performance or outcome assessment) were also unreported.However, subgroup analyses as well as sensitivity analyses or funnel plots indicated that treatment outcomes were not influenced by the quality of the included studies. On the other hand, we rated 'length of STT' and AEs for the main outcome as high-quality according to GRADE classification; but we downgraded 'publication date' quality to moderate, and 'geographic region' and 'antibiotic resistance' to low- and very low-quality, respectively. AUTHORS' CONCLUSIONS Our meta-analysis indicates that prior to 2008 SEQ was more effective than STT, especially when STT was given for only seven days. Nevertheless, the apparent advantage of sequential treatment has decreased over time, and more recent studies do not show SEQ to have a higher efficacy versus STT when STT is given for 10 days.Based on the results of this meta-analysis, although SEQ offers an advantage when compared with STT, it cannot be presented as a valid alternative, given that neither SEQ nor STT regimens achieved optimal efficacy ( ≥ 90% eradication rate).

Abstract
AIM: To evaluate the applicability of nonbismuth concomitant quadruple therapy for Helicobacter pylori (H. pylori) eradication in Chinese regions.
METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the efficacy of nonbismuth concomitant quadruple therapy between sequential therapy or triple therapy for H. pylori eradication in Chinese regions. The defined Chinese regions include China, Hong Kong, Taiwan, and Singapore. The primary outcome was the H. pylori eradication rate; the secondary outcome was the compliance with therapy. The PubMed, Embase, Scopus, and Cochrane databases were searched for studies published in the period up to March 2016 with no language restriction.
RESULTS: We reviewed six randomized controlled trials and 1616 patients. In 3 trials comparing concomitant quadruple therapy with triple therapy, the H. pylori eradication rate was significantly higher for 7-d nonbismuth concomitant quadruple therapy than for 7-d triple therapy (91.2% vs 77.9%, risk ratio = 1.17, 95%CI: 1.09-1.25). In 3 trials comparing quadruple therapy with sequential therapy, the eradication rate was not significant between groups (86.9% vs 86.0%). However, higher compliance was achieved with concomitant therapy than with sequential therapy.
CONCLUSION: The H. pylori eradication rate was higher for nonbismuth concomitant quadruple therapy than for triple therapy. Moreover, higher compliance was achieved with nonbismuth concomitant quadruple therapy than with sequential therapy. Thus, nonbismuth concomitant quadruple therapy should be the first-line treatment in Chinese regions.

Abstract
OBJECTIVES To compare triple therapy with sequential and concomitant therapies directly in a head-to-head comparison in Helicobacter pylori-infected patients. DESIGN Patients were allocated randomly as follows: a triple therapy with esomeprazole (20 mg), amoxicillin (1000 mg) and clarithromycin (500 mg) twice daily for 7 days; a sequential therapy with 5 days of esomeprazole (20 mg) and amoxicillin (1000 mg) twice daily, followed by 5 days of esomeprazole (20 mg), clarithromycin (500 mg) and metronidazole (400 mg) twice daily; or a concomitant therapy consisting of esomeprazole (20 mg), amoxicillin (1000 mg), clarithromycin (500 mg) and metronidazole (400 mg) twice daily for 7 days. RESULTS A total of 356 consecutive patients were included. The eradication rates for the triple, sequential and concomitant therapies were 83.6% [95% confidence interval (CI) 76.9-90.4%], 94.2% (95% CI 90.0-98.4%) and 91.7% (95% CI 86.7-96.6%), respectively, in the intention-to-treat population. The differences were significant only between triple and sequential therapies (P=0.01). The primary resistance rates to amoxicillin, clarithromycin and metronidazole were 0.6, 10.5 and 25.9%, respectively. Concomitant therapy was significantly better than triple therapy in cases with clarithromycin resistance (P=0.01). CONCLUSION Ten-day sequential therapy was significantly better than 7-day triple therapy in a clinical setting with low rates of clarithromycin and dual resistance. Concomitant therapy was significantly better than standard triple therapy in the subgroup of patients with clarithromycin-resistant strains.

Abstract
BACKGROUND With markedly increased antibiotic resistance and unsatisfactory efficacies of common empiric eradication regimens in the mainland of China, tailored therapy may be the best choice to achieve good efficacy. This study compared the eradication rates, safety, and compliance of tailored therapy to those of triple therapy plus bismuth and concomitant therapy in the naïve patients with Helicobacter pylori infection. MATERIALS AND METHODS Between September 2013 and April 2014, 1050 patients with H. pylori infection at three tertiary hospitals were randomly assigned to 10-day treatment with tailored, triple plus bismuth, or concomitant regimens. In tailored therapy, medications were adjusted according to clarithromycin sensitivity and cytochrome P450 isoenzyme 2C19 genotype. The antimicrobial susceptibility testing (E test) was performed. Eradication status was assessed 4-12 weeks after treatment. RESULTS The eradication rate was significantly higher in tailored group than in triple plus bismuth and concomitant groups in both intention-to-treat (88.7 vs 77.4 vs 78.3%, p < .001) and per-protocol (93.3 vs 87.0 vs 87.4%, p = .021) analyses in a setting with high antibiotic resistance (clarithromycin 48.8%, metronidazole 65.7%, and dual resistance 35.3%). Significantly, fewer adverse effects occurred in tailored group than in concomitant group (22.0 vs 31.7%, p = .018). The eradication rates of dual clarithromycin and metronidazole resistance, isolated clarithromycin resistance, isolated metronidazole resistance, and dual susceptible were 78.7, 82.4, 94.8, and 94.4% in triple therapy plus bismuth and 75.9, 87.2, 92.9, and 95.2% in concomitant therapy, respectively. CONCLUSIONS First-line tailored therapy achieves significantly higher eradication rates and fewer side effects, compared to triple therapy plus bismuth and concomitant therapy in a setting with high rates of clarithromycin and metronidazole resistance.

Abstract
BACKGROUND Widespread use of antibiotics has resulted in increased rates of antibiotic resistance and decreased rates of Helicobacter pylori (H. pylori) eradication, leading to a search for newer therapeutic options. This study aimed to examine the efficacy, tolerability, and patient compliance of a first-line bismuth-containing 5-day concomitant quintuple therapy. MATERIALS AND METHODS This prospective study included 144 eradication treatment naïve H. pylori positive patients with dyspeptic complaints. Patients received the following concomitant quintuple therapy for 5 days: bismuth subcitrate 300 mg q.i.d, omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg t.i.d. Eradication was assessed with H. pylori stool antigen test or urea-breath test 6 weeks after the completion of therapy. RESULTS Treatment compliance rate in this study was 97.2%. Intention to treat and per-protocol eradication rates were 134/144 (93.1%, 95% CI, 88.9-97.2) and 134/140 (95.7%, 95% CI, 92.2-98.6), respectively. Side effect was reported by 8.5% of the patients that attended follow-up visits, including epigastric pain (2.8%), nausea/vomiting (2.1%), diarrhea (1.4%), taste disturbance (1.4%), and fatigue (0.7%). CONCLUSIONS Bismuth-containing, short course, quintuple concomitant therapy appears to be an effective and safe therapeutic option for the first-line H. pylori eradication, particularly in populations with high resistance.

Abstract
OBJECTIVES Comparison of Helicobacter pylori eradication rates, side effects, compliance, cost, and ulcer recurrence of sequential therapy (ST) with that of concomitant therapy (CT) in patients with perforated duodenal ulcer following simple omental patch closure. METHODS Sixty-eight patients with perforated duodenal ulcer treated with simple closure and found to be H. pylori positive on three months follow-up were randomized to receive either ST or CT for H. pylori eradication. Urease test and Giemsa stain were used to assess for H. pylori eradication status. Follow-up endoscopies were done after 3 months, 6 months, and 1 year to evaluate the ulcer recurrence. RESULTS H. pylori eradication rates were similar in ST and CT groups on intention-to-treat (ITT) analysis (71.43% vs 81.80%,P = 0.40). Similar eradication rates were also found in per-protocol (PP) analysis (86.20% vs 90%,P = 0.71). Ulcer recurrence rate in ST groups and CT groups at 3 months (17.14% vs 6.06%,P = 0.26), 6 months (22.86% vs 9.09%,P = 0.19), and at 1 year (25.71% vs 15.15%,P = 0.37) of follow-up was also similar by ITT analysis. Compliance and side effects to therapies were comparable between the groups. The most common side effects were diarrhoea and metallic taste in ST and CT groups, respectively. A complete course of ST costs Indian Rupees (INR) 570.00, whereas CT costs INR 1080.00. CONCLUSION H. pylori eradication rates, side effects, compliance, cost, and ulcer recurrences were similar between the two groups. The ST was more economical compared with CT.

Abstract
INTRODUCTION Treatment of Helicobacter pylori (H. pylori) infection is paramount for the management of prevalent gastrointestinal disorders and in the prevention of gastric cancer. Due to increasing antimicrobial resistance, performance of standard triple therapies has now declined to unacceptably low levels. AREAS COVERED In this article: i) we critically revise optimization tools aiming to improve the outcome of standard treatments; ii) we provide updated evidence on the efficacy and rationale for the use of several non-bismuth quadruple regimens in clinical practice, recommended as preferred empirical therapies in areas of high clarithromycin resistance. EXPERT OPINION Prolonged (14-day) treatment duration may boost the efficacy of standard triple therapy by approximately 5%. Use of a high-dose PPI and/or new-generation PPIs, rabeprazole and esomeprazole, might improve eradication rates, particularly in regions where the CYP2C19 rapid metabolizer phenotype is prevalent. Adjunctive probiotics may be considered to improve treatment tolerability, though more data are required to better define their role in H. pylori eradication. Among non-bismuth quadruple regimens, both concomitant and sequential therapies are appropriate options for high-resistance settings; however, concomitant therapy appears to be less impaired by dual clarithromycin/metronidazole resistance. Hybrid therapy is a promising new alternative which seems not to be inferior to concomitant therapy.

Abstract
BACKGROUND AND AIMS This study aimed to validate the equivalence of first-line concomitant and hybrid regimens for Helicobacter pylori infection in an era of increasing antibiotic resistance. The study also aimed to assess regimen compliance. METHODS H. pylori-infected patients from six hospitals in Korea were randomly assigned to either concomitant or hybrid regimens. The concomitant regimen consisted of 20 mg of esomeprazole, 1 g of amoxicillin, 500 mg of clarithromycin, and 500 mg metronidazole, twice daily for 10 days. The hybrid regimen consisted of a 5-day dual therapy (20 mg of esomeprazole and 1 g of amoxicillin, twice daily) followed by a 5-day quadruple therapy (20 mg of esomeprazole, 1 g of amoxicillin, 500 mg of clarithromycin, and 500 mg of metronidazole, twice daily). RESULTS Eradication rates for concomitant and hybrid therapy were 78.6% (187/238) and 78.8% (190/241) in the intention-to-treat analysis, and 89.8% (176/196) and 89.6% (181/202) in the per protocol analysis. For both analyses, 95% confidence intervals fell within the ± 8% equivalence margin. Adherence was better in the hybrid group (95.0%) than in the concomitant group (90.1%), a difference that was borderline significant (P = 0.051). Adverse event rates were higher in the concomitant group than in the hybrid group for nausea (15.8% vs 8.8%; P = 0.028) and regurgitation (17.6% vs 10.7%; P = 0.040). CONCLUSION As compared with concomitant therapy, hybrid therapy offered similar efficacy, better compliance, and fewer adverse events. Hybrid therapy could be a reasonable first-line treatment option for H. pylori in areas with high antibiotics resistance.

Abstract
BACKGROUND AND AIM Eradication of Helicobacter pylori (H. pylori) infection with triple therapy (TT) has declined in many countries prompting the search for alternative regimens. Sequential therapy (ST) and concomitant therapy (CT) have been suggested as first-line regimens in areas of high clarithromycin resistance. We performed a meta-analysis to compare the eradication rates of CT with ST for H. pylori. METHODS A comprehensive literature search for studies comparing the efficacy of CT with ST was performed. Dichotomous data were pooled to obtain the odds ratio (OR) of the eradication rate with 95% confidence intervals (CIs). The eradication rates were considered both on an intention-to-treat (ITT) and on a per-protocol (PP) bases. RESULTS A total of 7 studies provided data on 2412 adult patients. Pooled estimates of the studies revealed no significant differences between CT and ST. The pooled OR was 1.116 (95% CI: 0.795-1.567, P = 0.526) for ITT analysis and 1.153 (95% CI: 0.793-1.677, P = 0.455) for PP analysis. There was no difference in the rate of adverse events (OR: 1.229, 95% CI: 0.971-1.556, P = 0.086) and compliance (OR: 0.945, 95% CI: 0.722-1.237, P = 0.681) between the two regimens. Subgroup analysis was performed to compare CT of 10 days and 5 days with ST of 10 days. The pooled OR was 1.518 for CT of 10 days and 0.636 for CT of 5 days. CONCLUSIONS CT regimens did not achieve higher eradication rates compared with the ST regimen. The adverse events and adherence to medications were not different between the two regimens.

Seven-Day Nonbismuth Containing Quadruple Therapy Could Achieve a Grade "A" Success Rate for First-Line Helicobacter pylori Eradication. BIOMED RESEARCH INTERNATIONAL 2015; 2015:623732. [PMID: 26090428 PMCID: PMC4452293 DOI: 10.1155/2015/623732] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Accepted: 01/10/2015] [Indexed: 01/10/2023]
Abstract
This prospective study was to assess the efficacy of nonbismuth containing quadruple therapy as first-line H. pylori treatment and to determine the clinical factors influencing patient outcome. We enrolled 200 H. pylori-infected naïve patients. They were prescribed either a 7-day nonbismuth containing quadruple therapy group (EACM, esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, metronidazole 500 mg twice daily, and clarithromycin 500 mg twice daily) or a 7-day standard triple therapy group (EAC, esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily). Follow-up studies to assess treatment responses were carried out 8 weeks later. The eradication rates attained by EACM and EAC groups were 95.6% (95% confidence interval [CI] = 89.4%–98.3%) and 79.3% (95% CI = 70%–86.4%) in the per-protocol analysis (P < 0.001) and 88% (95% CI = 80.2%–93.0%) and 73% (95% I = 63.6%–80.3%) in the intention-to-treat analysis (P = 0.007). Clarithromycin resistance, metronidazole resistance, and dual clarithromycin and metronidazole resistances were the clinical factors influencing H. pylori eradication in EACM group. Clarithromycin resistance and dual clarithromycin and metronidazole resistances were the influential factor for EAC treatment. In conclusion, the results suggest that 7-day nonbismuth containing quadruple therapy could achieve a grade “A” report card for first-line H. pylori treatment.

Abstract
OBJECTIVE To compare the efficacy of sequential therapy, concomitant therapy and hybrid therapy for the treatment of Helicobacter pylori (H. pylori) infection. METHODS PubMed, Web of Science, Medline, Embase, the Cochrane Central Register of Controlled Trials and CNKI were searched up to the end of May 10, 2014 in order to identify all randomized controlled trials (RCTs) reporting the effects of sequential therapy, concomitant therapy and hybrid therapy on H. pylori eradication. The relative risk (RR) of eradicating H. pylori infection after sequential therapy compared with concomitant therapy or hybrid therapy was pooled. The eradication rates were considered both on an intention-to-treat (ITT) and per-protocol (PP) basis. RESULTS A total of 10 RCTs involving 3,501 patients were included. The pooled data suggested that the differences between the three groups were not statistically significant (ITT analysis: sequential therapy vs. concomitant therapy: RR=1.01, 95%confidence interval (CI): 0.97-1.04, sequential therapy vs. hybrid therapy: RR=1.02, 95%CI: 0.85-1.22, concomitant therapy vs. hybrid therapy: RR=1.03, 95%CI: 0.97-1.08; PP analysis: sequential therapy vs. concomitant therapy: RR=1.00, 95%CI: 0.96-1.03, sequential therapy vs. hybrid therapy: RR=0.97, 95%CI: 0.86-1.09, concomitant therapy vs. hybrid therapy: RR=1.01, 95%CI: 0.93-1.10). In the ITT and PP analyses, the overall eradication rates were 84.3% (95%CI: 79.1-89.4) and 86.4% (95%CI: 81.7-91.0) for the sequential therapy group, 86.7% (95%CI: 81.0-92.3) and 89.8% (95%CI: 85.1-94.5) for the concomitant therapy group and 86.6% (95%CI: 82.3-91.0) and 92.7% (95%CI: 90.5-94.9) for the hybrid therapy group, respectively. There were no significant differences among these therapies in terms of the rate of side effects. CONCLUSION The pooled evidence suggests that sequential therapy, concomitant therapy and hybrid therapy are similar with respect to the treatment of H. pylori infection.

Abstract
BACKGROUND Current treatment of Helicobacter pylori consists of three or four drugs for 7-14 days with important associated cost and adverse events. AIMS This study compared efficacy and safety of standard dose vs. half-dose concomitant nonbismuth quadruple therapy (NBQT) for 7 days. The standard dose consisted of twice daily rabeprazole 20 mg, amoxicillin 1 g, metronidazole 500 mg, and clarithromycin 500 mg. METHODS This was a prospective randomized trial. (14)C-urea breath test was performed ≥4 weeks after treatment and ≥2 weeks off acid suppressive therapy. Compliance and adverse events were monitored during treatment. RESULTS A total of 200 consecutive treatment-naïve patients were enrolled. Baseline characteristics were similar between groups, with 15.5% of subjects reporting prior macrolide use. Eradication occurred in 78% (95% CI 68.6-85.7%) in both groups on intention-to-treat analysis. Per-protocol rates were 82.1 vs. 83.9% for standard-dose patients vs. half-dose patients, respectively (p = NS). Adverse events (only mild) were reported in 57 vs. 41% of standard-dose patients vs. half-dose patients (p = 0.024), with metallic taste and nausea notably less frequent in the latter (36 vs. 12% and 18 vs. 7%, respectively; p < 0.05 for both). Overall, eradication failed in 38.7% of prior macrolide users vs. 18.9% without such exposure (p = 0.019). On multivariate logistic regression, prior macrolide exposure was the only factor associated with failed eradication (OR 2.60, 95% CI 1.06-6.39; p = 0.038). Treatment was cheaper with the half-dose regimen. INTERPRETATION A 50% reduction in antibiotic dosage does not diminish efficacy of concomitant nonbismuth quadruple therapy but leads to significant reduction in cost and adverse events. Seven-day concomitant NBQT is suboptimal for H. pylori independent of prior macrolide exposure.

Abstract
OPINION STATEMENT Once easily eradicated with triple or quadruple therapy, Helicobacter pylori infection has become increasingly resistant to traditional first-line treatment regimens because of emerging antibiotic resistance coupled with poor patient compliance with completing the treatment course. Given decreasing H. pylori eradication rates, there is considerable interest in evaluating new antibiotic combinations and regimens, the addition of probiotics, and the development of new paradigms such as concomitant, sequential, and hybrid medication dosing strategies. Unfortunately, efforts thus far have not universally improved treatment responses, as promising early results were often not extrapolated to wider populations. This is probably due largely to regional variation in H. pylori resistance patterns. Ideally, the standard of care should be dictated by knowledge of local H. pylori antimicrobial resistance patterns and clinical success rates rather than by empiric extrapolation from the literature. Unfortunately, such knowledge is usually lacking in the USA. The expectation of a first-line regimen is a minimum 80 % eradication rate in the local population. Standard triple therapy with a proton pump inhibitor (PPI), amoxicillin, and clarithromycin may still be effective in some areas; however, in populations with high clarithromycin resistance, quadruple therapy with a metronidazole-based regimen may be a better choice, and concomitant, sequential, or hybrid dosing schedules should also be considered as possible first-line choices. Second- and third-line treatment regimens consist of levofloxacin-based and rifabutin-based therapies, respectively. Further work should be directed at establishing local resistance patterns and eradication rates, developing H. pylori-specific antibiotics, and starting culture-guided treatment programs. Ultimately, the development of an H. pylori vaccine would bypass any issues with antibiotic resistance by preventing the acquisition of infection altogether.

Abstract
The standard therapy for Helicobacter pylori infection in Korea is a triple-drug regimen consisting of a proton pump inhibitor with two antibiotics such as clarithromycin, amoxicillin, and metronidazole. However, as the eradication rate of this regimen has declined over the past decade, this prompted the formulation of new therapeutic regimens. New therapeutic strategies against H. pylori infection that had been tried all over the world include sequential therapy, concomitant therapy, and tailored therapy This article will review the basic concepts and the results of previous clinical trials on the aforementioned new therapeutic regiments.

Abstract
The efficacy of triple therapy for Helicobacter pylori infection has dramatically declined over the last decade, largely related to increasing clarithromycin resistance rates. From a microbiological standpoint, bismuth quadruple therapy is the ideal replacement since it combines drugs for which resistance does not impair its efficacy. Nonetheless, several obstacles such as availability, complexity or tolerance prevent a general implementation of bismuth quadruple therapy, so non-bismuth quadruple regimens remain the best first-line treatment in clinical practice in many geographical areas. We review the rationale and efficacy of several optimization tools (increasing the length of duration, high-dose acid suppression, probiotics), which have been largely evaluated over the last 5 years to increase the effectiveness of standard triple therapy. Then, we update available evidence on the effectiveness of several non-bismuth quadruple therapies (sequential, concomitant, hybrid, miscellaneous therapy), which have gained interest lately. We also revise evidence on the efficacy of the aforementioned optimization tools for non-bismuth quadruples schemes and, finally we provide a novel regionalized therapeutic algorithm, based on novel formulas recently developed for predicting the outcome of non-bismuth quadruple regimens, upon local antibiotic resistance rates.

Abstract
Standard triple therapy, consisting of a proton pump inhibitor, plus amoxicillin and clarithromycin, has been the most commonly used first-line treatment regimen for Helicobacter pylori (H. pylori) eradication for many years worldwide. However, as a result of increased resistance to antibiotics, H. pylori eradication rates with use of standard triple therapy have been declining and recently reached < 80% in many countries. Several new strategies to enhance the eradication rate of H. pylori have been studied. Currently, among the alternative first-line eradication regimens, concomitant and hybrid regimens have shown excellent results and could be the optimal treatment option. Although clinical usefulness of rescue therapy for patients in whom eradication of H. pylori with non-bismuth quadruple regimen has failed is unclear, levofloxacin-based quadruple therapy has shown promise as a rescue treatment. The choice of third-line therapy depends on factors such as the local pattern of antibiotic resistance, drug availability, and previous treatment. We hope that a simple method for detection of antibiotic susceptibility using polymerase chain reaction would be a possible alternative to administration of “tailored treatment” in the era of increasing prevalence of antimicrobial resistance.

Abstract
OBJECTIVES Studies conducted in large populations of patients and providing full information on Helicobacter pylori (H. pylori) antibiotic resistance are needed to determine the efficacy of sequential therapy (SQT) against this pathogen. This study compared eradication rates with SQT and standard triple therapy (STT), and evaluated the impact of antibiotic resistance on outcomes. METHODS The study population included adults with positive H. pylori culture presenting at four centers in China between March 2008 and December 2010. Patients were randomly assigned to 10 days of treatment with esomeprazole, amoxicillin, and clarithromycin (STT; n=140) or to 5 days of treatment with esomeprazole and amoxicillin, followed by 5 days of esomeprazole, clarithromycin, and tinidazole (SQT; n=140). Eradication was assessed 8-12 weeks after treatment. RESULTS There was no significant difference between the eradication rates achieved with STT (66.4% (95% confidence interval (CI) 59.3-74.3)) and SQT (72.1% (65.0-79.3); P=0.300) in either the intention-to-treat analysis or the per-protocol analysis (72.7% (65.6-79.7) and 76.5% (69.7-83.3), respectively; P=0.475). Clarithromycin resistance (CLA-R, odds ratio (OR)=8.34 (3.13-22.26), P<0.001) and metronidazole resistance (MET-R, OR=7.14 (1.52-33.53), P=0.013) both independently predicted treatment failure in the SQT group. Patients in the SQT group with dual CLA-R and MET-R had a lower eradication rate (43.9%) than those with isolated CLA-R (88.9%, P=0.024) or isolated MET-R (87.8%, P<0.001). CONCLUSIONS H. pylori eradication rates with STT and SQT were compromised by antibiotic resistance. SQT may be suitable in regions with high prevalence of isolated CLA-R, but it is unsatisfactory when both CLA-R and MET-R are present.

Abstract
OBJECTIVES No trial has compared non-bismuth quadruple 'sequential' and 'concomitant' regimens in settings with increasing clarithromycin rates. The study aims to compare the effectiveness and safety of these therapies for Helicobacter pylori treatment. DESIGN Prospective randomised clinical trial in 11 Spanish hospitals. Patients naïve to eradication therapy with non-investigated/functional dyspepsia or peptic ulcer disease were included. Randomised (1:1) to sequential (omeprazole (20 mg/12 h) and amoxicillin (1 g/12 h) for 5 days, followed by 5 days of omeprazole (20 mg/12 h), clarithromycin (500 mg/12 h) and metronidazole (500 mg/12 h)), or concomitant treatment (same drugs taken concomitantly for 10 days). Eradication was confirmed with (13)C-urea breath test or histology 4 weeks after treatment. Adverse events (AEs) and compliance were evaluated with questionnaires and residual medication count. RESULTS 338 consecutive patients were randomised. Mean age was 47 years, 60% were women, 22% smokers and 20% had peptic ulcer. Concomitant and sequential eradication rates were, respectively, 87% vs 81% by intention-to-treat (p=0.15) and 91% vs 86% (p=0.131) per protocol. Respective compliances were 83% vs 82%. Treatment-emergent AEs were reported in 59% of patients (no differences found between treatments). AEs were mostly mild (60%), and average length was 6.1 days, causing discontinuation only in 12 patients. Multivariate analysis: 'concomitant' treatment showed an OR of 1.5 towards better eradication rate in a borderline significance CI (95% CI 0.9 to 2.8). CONCLUSIONS Concomitant therapy led to a non-statistically significant advantage (5%) over sequential therapy, coming closer to 90% cure rates. Both therapies showed an acceptable safety profile.

Abstract
AIM To document the efficacy and tolerability of 14-day bismuth-lansoprazole-amoxicillin-clarithromycin (BLAC) regimen for Helicobacter pylori (H. pylori) eradication as a first-line therapy. METHOD Patients were considered eligible for the study if they underwent upper gastrointestinal endoscopy, and H. pylori infection was diagnosed through histologic examination of antral and body biopsy samples. Primary end point of this study was to evaluate the eradication rate of 14-day BLAC regimen therapies. H. pylori eradication was assessed using the 13C urea breath test performed 6 weeks after the completion of treatment. All patients were asked to fill in a validated questionnaire to report therapy-related side effects. Each symptom was graded from absent or present. RESULTS Ninety-seven (21 men and 76 women) were enrolled. All the patients completed the study. The H. pylori eradication rate was 90.7% (88 of 97 patients). Side effects were observed in reasonable percentages, and none of the patients left the study because of drug side effect. CONCLUSION Bismuth-lansoprazole-amoxicillin-clarithromycin regimen as a 2-week course achieved an acceptable eradication rate with relatively mild side effects.

Abstract
This article summarizes the main conclusions drawn from the studies presented in Digestive Disease Week in 2012 on Helicobacter pylori infection. In developed countries, the prevalence of this infection has decreased, although it continues to be high. The prevalence in Spain is high (50%) and does not seem to be decreasing. There is an increase in antibiotic resistance, which is correlated with the frequency of prior antibiotic prescription. H. pylori eradication improves the symptoms of "epigastric pain syndrome" in functional dyspepsia. The frequency of idiopathic peptic ulcers seems to be increasing. To prevent the development of gastric cancer, eradication therapy should be administered early (before intestinal metaplasia develops). H. pylori eradication in patients undergoing early endoscopic resection of gastric cancer reduces the incidence of metachronous tumors, although endoscopic follow-up should be performed periodically. H. pylori eradication induces MALT lymphoma regression in most patients and tumoral recurrence in the long term is exceptional; radiotherapy is an excellent second-line option; a watch and wait approach to histologic recurrence after initial MALT lymphoma remission is a reasonable alternative. Idiopathic thrombocytopenic purpura is an indication for eradication therapy in children as well as adults. There are several diagnostic innovations, such as high-resolution endoscopy, narrow-band imaging, a method based on the electrochemical properties of H. pylori, and the cytosponge. Quadruple therapy with bismuth is at least as effective as standard triple therapy. The superiority of "sequential" therapy over standard triple therapy should be confirmed in distinct settings. The efficacy of "concomitant" therapy is similar -or even better- than that of "sequential" therapy, but has the advantage of being simpler. A hybrid sequential-concomitant therapy is highly effective. In patients allergic to beta-lactams, the efficacy of treatment with a proton pump inhibitor-clarithromycin-metronidazole is insufficient. When standard triple therapy fails, the second-line option of a 10-day course of levofloxacin is effective and is simpler and better tolerated than quadruple therapy. Triple therapy with levofloxacin is also a promising alternative after failure of "sequential" and "concomitant" therapy. New-generation quinolones, such as moxifloxacin and sitafloxacin, could be useful as eradication therapy, especially as rescue therapy. When two eradication therapies have failed, empirical administration of a third (e.g. levofloxacin) is a valid option. Even after three eradication therapies have failed, an empirical rescue therapy (with rifabutin) can be effective. H. pylori reinfection is highly frequent in developing countries, probably due to intrafamilial transmission.

Abstract
This review summarizes important studies regarding Helicobacter pylori therapy published from April 2012 up to March 2013. To begin with, the updated European Consensus Guidelines were published last year, highlighting the role of bismuth and nonbismuth quadruple regimen as first-line treatments. Cure rates for standard triple therapy remain acceptable in quite a few settings nowadays, and some reports on innovative triple therapies look promising. One study evaluating bismuth quadruple therapy as first-line therapy was reported. Regarding nonbismuth quadruple regimens, there is a trend of superiority emerging for the "concomitant" therapy over the "sequential" regimen. "Hybrid" therapy, a combination of sequential and concomitant therapy, has also shown advantage over sequential therapy. Levofloxacin-based therapies appear to be useful and versatile in second- and third-line therapies, with interesting results for newer generation quinolones, which may partially overcome antibiotic resistance. Some promising works have been reported for bismuth-based rescue therapy, using individualized therapies upon antimicrobial information, as well as for rifabutin fourth-line therapy. Probiotics appear to have an effect in terms of reducing side effects and improving compliance, but data on improvement of eradication rates remain controversial.

Abstract
OBJECTIVE To do a systematic review and meta-analysis of studies comparing sequential therapy for eradication of Helicobacter pylori with pre-existing and new therapies, thus providing a glimpse of eradication success worldwide. DESIGN Systematic review and meta-analysis. DATA SOURCES Medline, Embase, and Cochrane Central Register of Controlled Trials up to May 2013; abstract books of major European, American, and Asian gastroenterological meetings. STUDY SELECTION Randomised controlled trials in previously untreated adults, in which sequential therapy was compared with a pre-existing or new therapy. RESULTS 46 randomised controlled trials were reviewed and analysed. 5666 patients were randomised to sequential therapy and 7866 to other (established and new) treatments. The overall eradication rate of sequential therapy was 84.3% (95% confidence interval 82.1% to 86.4%). Sequential therapy was superior to seven day triple therapy (relative risk 1.21, 95% confidence interval 1.17 to 1.25; I(2)=29.3%; number needed to treat 6, 95% confidence interval 5% to 7%), marginally superior to 10 day triple therapy (1.11, 1.04 to 1.19; I(2)= 67.2%; NNT 10, 7 to 15), but not superior to 14 day triple therapy (1.00, 0.94 to 1.06; I(2)=54.3%), bismuth based therapy (1.01, 0.95 to 1.06; I(2)=21.1%), and non-bismuth based therapy (0.99, 0.94 to 1.05; I(2)=52.3%). Data on eradication according to pre-treatment antimicrobial susceptibility testing were available in eight studies, and sequential therapy was able to eradicate 72.8% (61.6% to 82.8%) of the strains resistant to clarithromycin. CONCLUSIONS Eradication rates with pre-existing and new therapies for H pylori are suboptimal. Regional monitoring of resistance rates should help to guide treatment, and new agents for treatment need to be developed.
