ObjectiveTo determine the optimal regimen of different first-line Helicobacter pylori eradication therapies according to the clarithromycin resistance rate.DesignElectronic search for articles published between January 2005 and April 2016. Randomised, controlled trials that reported the effectiveness of first-line eradication therapies in treatment-naïve adults were included. Two independent reviewers performed articles screening and data extraction. Network and traditional meta-analyses were conducted using the random effect model. Subgroup analyses were performed to determine the ranking of regimens in countries with high (>15%) and low (<15%) clarithromycin resistance. Data including adverse events and therapeutic cure rate were also extracted and analysed.Results117 trials (totally 32 852 patients) for 17 H. pylori eradication regimens were eligible for inclusion. Compared with 7-day clarithromycin-based triple therapy, sequential therapy (ST) for 14 days had the highest effectiveness (OR=3.74, 95% CrI 2.37 to 5.96). ST-14 (OR=6.53, 95% CrI 3.23 to 13.63) and hybrid therapy (HY) for 10 days or more (OR=2.85, 95% CrI 1.58 to 5.37) represented the most effective regimen in areas with high and low clarithromycin resistance, respectively. The effectiveness of standard triple therapy was below therapeutic eradication rate in most of the countries. Longer duration was associated with higher eradication rate, but with a higher risk of events that lead to discontinuation.ConclusionsST and HY appeared to be the most effective therapies in countries with high and low clarithromycin resistance, respectively. The clinical decision for optimal regimen can be supported by referring to the rank ordering of relative efficacies stratified by local eradication rates, antibiotic resistance and safety profile.Trial registration numberCRD42015025445.

Bismuth Subcitrate

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.

Introduction: Helicobacter pylori eradication has become increasingly difficult as resistances to several antibiotics develop. We aimed to compare Helicobacter pylori eradication rates between triple therapy and sequential therapy in a naive Portuguese population.Material and Methods: Prospective randomized trial including consecutive patients referred for first-line Helicobacter pylori eradication treatment. Exclusion criteria: previous gastric surgery/neoplasia, pregnancy/lactancy, allergy to any of the drugs. The compared eradication regimens were triple therapy (pantoprazol, amoxicillin and clarithromycin 12/12 hours, 14 days) and sequential therapy (pantoprazol 12/12 hours for 10 days, amoxicillin 12/12 hours for days 1 - 5 and clarithromycin plus metronidazol 12/12 hours during days 6 - 10). Eradication success was confirmed with urea breath test. Statistical analysis was performed with SPSS v21.0 and a p-value < 0.05 was considered statistically significant.Results: Included 60 patients, 39 (65%) female with mean age 52 years (SD ± 14.3). Treatment groups were homogeneous for gender, age, indication for treatment and smoking status. No statistical differences were encountered between sequential and triple therapy eradication rates (86.2% vs 77.4%, p = 0.379), global eradication rate was 82%. Tobacco consumption was associated with a significantly lower eradication success (54.5 vs 87.8%, p = 0.022).Discussion: In this randomized controlled trial in a naive Portuguese population, we found a satisfactory global Helicobacter pylori eradication rate of 82%, with no statistical differences observed in the efficacy of the treatment between triple and sequential regimens.Conclusion: These results support the use of either therapy for the first-line eradication of Helicobacter pylori.

The most commonly used regimen forHelicobacter pyloritherapy at present is twice-daily proton pump inhibitor (PPI)-based triple therapy. Bismuth-based therapy is the next most common treatment used by gastroenterologists. When a PPI is combined with bismuth-based triple therapy (quadruple therapy), eradication rates are increased as compared with the triple therapy alone. Three separate randomized trials from three continents that compare quadruple therapy and PPIbased triple therapy revealed remarkably similar results. Eradication rates with PPI-based triple therapy and quadruple therapy were not significantly different. The eradication rates with quadruple therapy were 3% to 6% higher than PPI triple therapy, indicating that quadruple therapy should be no less effective than PPI triple therapy. Furthermore, these two therapies had similar rates of compliance and adverse events.The major potential benefit of the quadruple therapy relates to antibiotic resistance. In patients with clarithromycin resistance, PPIbased triple therapy, but not quadruple therapy, had a significantly lower eradication rate. However, due to its ability to largely overcome metronidazole resistance, quadruple therapy had little if any decrement in eradication rates compared with PPI triple therapy in patients with metronidazole-resistantH pylori. Therefore, quadruple therapy can be considered a first line therapy forH pylori.

Background & Aims: H. pylori eradication is strongly affected by various factors, including the ongoing antibiotic resistance. We describe a “real life” scenario in patients managed for H. pylori-related conditions, living in a southern Italian region (Apulia), an area with clarithromycin resistance >15%.Methods: 2,224 subjects were studied in two tertiary referral centers in Apulia. Analyses included: reason for referral, H. pylori infection rates (13C-urea breath test – UBT or upper endoscopy), and eradication rates following distinct regimens previously prescribed or prospectively prescribed (such as the bismuth-based quadruple therapy Pylera®, recently marketed in Italy).Results. Over 80% of the patients were referred by family physicians (60% naïve subjects). The overall infection rate was 32.5% and it was similar in asymptomatic patients (31.1%) or with H. pylori-related symptoms/clinical conditions (34.3%). In the 987 H. pylori+ve patients receiving therapy, the overall eradication rate was 80.2% (ITT). Observed eradication rate varied greatly across different regimens: 57.1% (2nd line levofloxacin), 59.6% (unconventional), 70.7% (7-day triple), 73.2% (7-day undefined), 89% (10-day sequential) and 96.9% (ITT, 10 day Pylera®, 1st to 5th line regimens given to 227 patients).Conclusions. A heterogeneous “real life” scenario in Southern Europe shows that H. pylori+ve patients are put at risk of poor outcomes and points to the need of a susceptibility-based therapy according to guidelines and local microbial resistance. In the present setting (i.e. high clarithromycin resistance), despite the high observed eradication rate, sequential therapy should not be recommended (absent in guidelines, unneeded antibiotic). Bismuth-based quadruple treatment (1st, 2nd or subsequent lines) yields the highest eradication rates.Abbreviations: ALT: Altamura; BA: Bari; EGDS: esophagogastroduodenoscopy; GERD: gastro-esophageal reflux disease; H. pylori: Helicobacter pylori; ITT: intention-to-treat; PP: per-protocol; PPI: proton pump inhibitor; UBT: urea breath test.

BackgroundCurrent guidelines recommend bismuth-containing quadruple therapy (BQT) and quinolone-containing therapy after failure of first-line Helicobacter pylori eradication therapy. However, the optimum regimen of second-line eradication therapy remains elusive. We conducted a network meta-analysis to compare the relative efficacy of 16 second-line H. pylori eradication regimens.MethodsThree major bibliographic databases were reviewed to enrol relevant randomised controlled trials between January 2000 and September 2018. Network meta-analysis was conducted by STATA software and we performed subgroup analysis in countries with high clarithromycin resistance and high levofloxacin resistance, and in patients with documented failure of first-line triple therapy.ResultsFifty-four studies totalling 8752 participants who received 16 regimens were eligible for analysis. Compared with a 7-day BQT, use of probiotic add-on therapy during, before, and after second-line antibiotic regimens, quinolone-based sequential therapy for 10–14 days, quinolone-based bismuth quadruple therapy for 10–14 days, bismuth quadruple therapy for 10–14 days, and quinolone-based triple therapy for 10–14 days were significantly superior to the other regimens. Subgroup analysis of countries with high clarithromycin resistance and high levofloxacin resistance revealed that the ranking of second-line eradication regimens was distributed similarly in each group, as well as in patients with failure of first-line triple therapy.ConclusionWe conducted a detailed comparison of second-line H. pylori regimens according to different antibiotic resistance rates and the results suggest alternative treatment choices with potential benefits beyond those that could be achieved using salvage therapies recommended by guidelines.
