BACKGROUND: SuccessfulHelicobacter pylorieradication with the traditional seven-day course of proton pump inhibitor (PPI) triple therapy is declining. Prolonging therapy to either 10 or 14 days is associated with better eradications rates.OBJECTIVE: To compare the effectiveness of 14-day course of triple therapy versus a 10-day course in the treatment ofH pyloriin Canada.METHODS: Consecutive treatment-naive patients with clinical indications forH pylorieradication underwent either a 10-day course or a 14-day course of traditional PPI triple therapy depending on the date of the office visit (an odd date received the 10-day course, whereas an even date received the 14-day treatment).H pylorieradication was ascertained via urea breath test or gastric biopsies performed ≥4 weeks after completion of therapy. Analyses were by both intention to treat and per-protocol.RESULTS: A total of 83 patients were included in the study (31 in the 10-day group and 52 in the 14-day group). In the intention-to-treat analysis, eradication rates were 82.7% (95% CI 70% to 92%) versus 45.2% (95% CI 27% to 64%), favouring the 14-day treatment (P<0.001). Similarly, in the per-protocol analysis, eradication rates were 91.5% (95% CI 80% to 98%) versus 63.6% (95% CI 41% to 83%), favouring the 14-day arm (P=0.01). Adverse events and compliance were not significantly different between the two groups.CONCLUSION: A 14-day course of standard PPI triple therapy was superior to a shorter-duration therapy and should be included as a first-line regimen forH pylorieradication in Canada. The 10-day course of treatment did not achieve an acceptable eradication rate and should no longer be used in this country.

<b><i>Backgrounds/Aims:</i></b> Vonoprazan (VPZ) is the first clinically available potassium competitive acid blocker. This class of agents provides faster and more potent acid inhibition than proton pump inhibitors. Most strains of <i>Helicobacter pylori</i> are sensitive to amoxicillin. We hypothesized that dual therapy with VPZ and amoxicillin would provide the sufficient eradication rate for <i>H. pylori</i> infection. To evaluate this, we compared the eradication rate by the dual VPZ/amoxicillin therapy with that by the standard triple VPZ/amoxicillin/clarithromycin therapy. <b><i>Methods:</i></b> Non-inferiority of the eradication rate of <i>H. pylori</i> by the dual therapy with VPZ 20 mg twice daily (bid) and amoxicillin 500 mg 3 times daily (tid) for 1 week to that by the triple therapy with VPZ 20 mg bid, amoxicillin 750 mg bid and clarithromycin 200 mg bid for 1 week was retrospectively studied. Propensity score matching was performed to improve comparability between 2 regimen groups. Successful eradication was diagnosed using the [<sup>13</sup>C]-urea breath test at 1–2 months after the end of eradication therapy. <b><i>Results:</i></b> The intention-to-treat analysis demonstrated that the eradication rate by the dual therapy (92.9%; 95% CI 82.7–98.0%, 52/56) was not inferior to that of the triple therapy (91.9%; 95% CI 80.4–97.0%, 51/56; OR 1.275, 95% CI 0.324–5.017%, <i>p</i> = 0.728). There were no statistically significant differences in incidences of adverse events between 2 regimens. <b><i>Conclusion:</i></b> VPZ-based dual therapy (VPZ 20 mg bid and amoxicillin 500 mg tid for 1 week) provides an acceptable eradication rate of <i>H. pylori</i> infection without the need for second antimicrobial agents, such as clarithromycin.

Background and Study Aims.To compare the effectiveness of two regimens, single-dose esomeprazole- and pantoprazole-based triple therapy, forHelicobacter pylori(H. pylori) eradication.Patients and Methods.A total of 453 patients were enrolled forH. pylorieradication. They were randomly assigned to either EAC group (Esomeprazole 40 mg once daily, Amoxicillin 1 g twice daily, Clarithromycin 500 mg twice daily for 7 days) or PAC group (Pantoprazole 40 mg twice daily, Amoxicillin 1 g twice daily, Clarithromycin 500 mg twice daily for 7 days). Follow-up endoscopy or urea breath test was scheduled 12–16 weeks after the eradication to evaluate the therapeutic response.Results.Higher eradication rate in EAC group than PAC group was shown by intention-to-treat analysis (EAC 72% versus PAC 55%,P<0.05) and per-protocol analysis (EAC 91% versus PAC 72%,P<0.05). The incidence of adverse effects (EAC 19% versus PAC 17%,P=0.712) and the compliance (EAC 87% versus PAC 91%,P=0.083) were comparable between these 2 groups.Conclusions.Single-dose esomeprazole-based triple therapy is effective forH. pylorieradication.

BACKGROUND:Helicobacter pylorieradication rates achieved by standard seven-day triple therapies are decreasing in several countries, while a novel 10-day sequential regimen has achieved a very high success rate. A longer 10-day triple therapy, similar to the sequential regimen, was tested to see whether it could achieve a better infection cure rate.METHODS: Patients with nonulcer dyspepsia andH pyloriinfection were randomly assigned to one of the following three therapies: esomeprazole 20 mg, clarithromycin 500 mg and amoxycillin 1 g for seven days or 10 days, or a 10-day sequential regimen including esomeprazole 20 mg plus amoxycillin 1 g for five days and esomeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg for the remaining five days. All drugs were given twice daily.H pylorieradication was checked four to six weeks after treatment by using a13C-urea breath test.RESULTS: Overall, 213 patients were enrolled.H pylorieradication was achieved in 75.7% and 77.9%, in 81.7% and 84.1%, and in 94.4% and 97.1% of patients following seven-day or 10-day triple therapy and the 10-day sequential regimen, at intention-to-treat and per protocol analyses, respectively. The eradication rate following the sequential regimen was higher than either seven-day (P=0.002) or 10-day triple therapy (P=0.02), while no significant difference emerged between the latter two regimens (P=0.6).CONCLUSIONS: The 10-day sequential regimen was significantly more effective than both triple regimens, while 10-day triple therapy failed to significantly increase theH pylorieradication rate achieved by the standard seven-day regimen.

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.

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.

BACKGROUND: Clarithromycin resistance has decreased the eradication rates ofHelicobacter pylori.AIMS: To determine whether a 10-day course of sequential therapy (ST) is more effective at eradicatingH pyloriinfection than triple therapy (TT) in the first or second line, and to assess side effects and compliance with therapy.METHODS: One hundred sixty treatment-naive and 40 non-treatment-naive patients who were positive forH pyloriinfection by13C-urea breath test or endoscopy were enrolled. Eighty of 160 patients underwent TT, while 80 of 160 underwent ST with omeprazole (20 mg) plus amoxicillin (1 g) twice/day for five days, followed by omeprazole (20 mg) with tinidazole (500 mg) twice/day and clarithromycin (500 mg) twice/day for five consecutive days.H pylorieradication was evaluated by13C-urea breath test no sooner than four weeks after the end of treatment.RESULTS: Eradication was achieved in 59 of 80 treatment-naive patients treated with TT (74%), in 74 of 80 patients treated with ST (93%), and in 38 of 40 non-treatment-naive patients (95%). Eradication rates in treatment-naive patients with ST were statistically significantly higher than TT (92.5% versus 73.7%; P=0.0015; OR 4.39 [95% CI 1.66 to 11.58]). Mild adverse effects were reported for both regimens.CONCLUSIONS: ST appears to be a well-tolerated, promising therapy; however, randomized controlled trials with larger and more diverse sample populations are needed before it can be recommended as a first-line treatment.

BACKGROUND:Helicobacter pyloriinfection occurs more frequently in Arctic Aboriginal settings than elsewhere in North America and Europe. Research aimed at reducing health risks fromH pyloriinfection has been conducted in the Aboriginal community of Aklavik, Northwest Territories.OBJECTIVE: To compare the effectiveness of the Canadian standard therapy with an alternative therapy for eliminatingH pyloriinfection in Aklavik.METHODS: Treatment-naiveH pylori-positive individuals were randomly assigned to a 10-day regimen (oral twice-daily doses) with rabeprazole (20 mg): standard triple therapy (proton pump inhibitor, added clarithromycin [500 mg] and amoxicillin [1 g] [PPI-CA]); sequential therapy (ST) added amoxicillin (1 g) on days 1 to 5, and metronidazole (500 mg) and clarithromycin (500 mg) on days 6 to 10. Participants with clarithromycin-resistantH pyloriwere randomly assigned to ST or quadruple therapy. Treatment effectiveness was estimated as per cent (95% CI) with a negative urea breath test at least 10 weeks after treatment.RESULTS: Of 104 (53 PPI-CA, 51 ST) randomized participants, 89 (49 PPI-CA, 40 ST) had post-treatment results. Per-protocol treatment effectiveness was 59% (95% CI 45% to 73%) for PPI-CA and 73% (95% CI 58% to 87%) for ST. Based on intention to treat, effectiveness was 55% (95% CI 41% to 69%) for PPI-CA and 57% (95% CI 43% to 71%) for ST. Of 77 participants (43 PPI-CA, 34 ST) with 100% adherence, effectiveness was 63% (95% CI 43% to 82%) for PPI-CA and 81% (95% CI 63% to 99%) for ST.CONCLUSIONS: While additional evidence is needed to confirm that ST is more effective for Arctic Aboriginal communities than the Canadian standardH pyloritreatment, these results show standard PPI-CA treatment to be inadequate for communities such as Aklavik.

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

Background & Aims: The updated Italian guidelines advise a standard 14-day triple therapy for first-line H. pylori eradication. This prospective study evaluated the cure rate following a 14-day triple therapy with either a standard or double-dose proton pump inhibitor (PPI). Methods. A total of 145 consecutive patients with H. pylori infection were randomized to receive a 14-day, first-line triple therapy with clarithromycin 500 mg, amoxicillin 1 g and esomeprazole at either 20 mg (standard therapy) or 40 mg (double-dose therapy), each given twice daily. Results. At intention-to-treat analysis, H. pylori infection was cured in 73.9% (95% CI: 63.9−84) and 81.9% (95% CI: 73−90.8) following standard and double-dose therapy, respectively, and in 78.2% (95% CI: 68.5−87.9) and 85.5% (95% CI: 77.2−93.8) at per-protocol analysis. No statistically significant difference occurred. Overall, 16.4% and 19.4% patients in the standard and double-dose therapy regimen complained of side effects. Conclusion. The success rate of both standard and double-dose 14-day triple therapies for first-line H. pylori treatment was unsatisfactory. A prolonged 14-day levofloxacin-based triple therapy for second-line H. pylori eradication seems to be promising. Abbrevations: ITT: Intention To Treat; NUD: non ulcer dyspepsia; PP: PerAdd Contributor Protocol; PPI: proton pump inhibitors; PUD: peptic ulcer disease; UBT: urea breath test.
