Background & Aims: In Japan, 7-day triple therapy for Helicobacter pylori including clarithromycin (CAM) was approved in 2000. However, antibiotic resistance subsequently reduced this rate to an unacceptable level (70%). Vonoprazan, an orally bioavailable potassium-competitive acid blocker (P-CAB), was approved in Japan in 2014. This could improve eradication rates by increasing the intragastric pH, thus increasing bacterial antibiotic susceptibility. This study compared the efficacy of 7-day triple therapies that included CAM and vonoprazan or proton pump inhibitor (PPI). Methods: We prospectively analyzed H. pylori eradication rates in 146 patients receiving 7-day triple therapy containing P-CAB (April 2015 to September 2015), and in a retrospective cohort of 1,305 patients who received 7-day triple therapy containing a PPI (April 2011 to September 2015). Results: H. pylori was eradicated in a significantly higher number of P-CAB-treated patients (89.7% [131/146]) than PPI-treated patients (73.9% [965/1305]; p < 0.05). The eradication rates in P-CAB-treated CAM-sensitive and CAM-resistant bacteria were 100% (44/44) and 87.5% (28/32), respectively, which were significantly higher than the corresponding rates in PPI-treated patients (88.0% [22/25] and 53.8% [7/13], p < 0.05).Conclusion: P-CAB improved the efficacy of CAM-containing 7-day triple therapy and would be a valuable first-line treatment for H. pylori infection.

Aims. To compare the efficacy and safety of vonoprazan-based versus proton pump inhibitor (PPI)-based triple therapy in the eradication of Helicobacter pylori. Methods. We performed a systematic search in PubMed, Embase, and the Cochrane Library databases for relevant randomized controlled trials up to March 2019. Studies were included if they compared the efficacy and safety of H. pylori eradication of vonoprazan-based and PPI-based triple therapy. Results. Three studies with 897 patients were evaluated in this meta-analysis. The H. pylori eradication rate of vonoprazan-based triple therapy was higher than that of PPI-based triple therapy as first-line regimens (intention-to-treat analysis: pooled eradication rates, 91.4% vs 74.8%; odds ratio [OR], 3.68; 95% confidence interval (CI): [1.87–7.26]; P<0.05). The incidence of adverse events in vonoprazan-based triple therapy was lower than that in PPI-based triple therapy (pooled incidence, 32.7% vs 40.5%; OR, 0.71; 95%CI: [0.53–0.95]; P<0.05). Conclusions. Efficacy of vonoprazan-based triple therapy is superior to that of PPI-based triple therapy for first-line H. pylori eradication. Additionally, vonoprazan-based triple therapy is better tolerated than PPI-based triple therapy.

Background There has been resurgence in the use of bismuth quadruple therapy (proton pump inhibitor, bismuth, tetracycline and metronidazole) for treating Helicobacter pylori infection thanks to a three-in-one single-capsule formulation. Objective To evaluate the effectiveness and safety of the single-capsule bismuth quadruple therapy. Methods Data were collected in a multicentre, prospective registry of the clinical practice of gastroenterologists on the management of H. pylori infection, where patients were registered at the Asociación Española de Gastroenterología REDCap database on an electronic case report form until January 2020. Effectiveness by modified intention-to-treat and per-protocol as well as multivariable analysis were performed. Independent factors evaluated were: age, gender, indication, compliance, proton pump inhibitor dose and treatment line. Results Finally, 2100 patients were prescribed single-capsule bismuth quadruple therapy following the technical sheet (i.e. three capsules every 6 hours for 10 days). The majority of these patients were naive (64%), with an average age of 50 years, 64% women and 16% with peptic ulcer. An overall modified intention-to-treat effectiveness of 92% was achieved. Eradication was over 90% in first-line treatment (95% modified intention-to-treat, n = 1166), and this was maintained as a rescue therapy, both in second (89% modified intention-to-treat, n = 375) and subsequent lines of therapy (third to sixth line: 92% modified intention-to-treat, n = 236). Compliance was the factor most closely associated with treatment effectiveness. Adverse events were generally mild to moderate, and 3% of patients reported a severe adverse event, leading to discontinuation of treatment in 1.7% of cases. Conclusions Single-capsule bismuth quadruple therapy achieved H. pylori eradication in approximately 90% of patients in real-world clinical practice, both as a first-line and rescue treatment, with good compliance and a favourable safety profile.

Background. As part of an observational multicenter prospective study European Registry on the management of Helicobacter pylori infection, conducted on the initiative of the European H. pylori and Microbiota Study Group, the compliance of clinical practice in the management of patients with Helicobacter pylori infection in Kazan with clinical guidelines was assessed. Materials and methods. The data of 437 patients included into the register by clinical sites in Kazan in 20132019 were analyzed. The methods used for the initial diagnosis of H. pylori infection and eradication control were evaluated. The frequency of various eradication therapy regimens prescription was analyzed in 379 cases. Data regarding the effectiveness of eradication therapy was analyzed in 173 patients. Results. The rapid urease test (44.2% of cases) and cytology/histology (60% of cases) were most often used for the initial diagnosis of H. pylori infection; however non-invasive methods such as 13C-urea breath (9.2%), serology (6.2%), H. pylori stool antigen test (2.3%) were less common. In 21.7% of patients two methods of H. pylori detection were used for primary diagnosis. The control test to evaluate the effectiveness of eradication therapy at the recommended timepoint was performed in 46.2% of patients. 13C-urea breath test (31.7%), stool PCR/stool antigen test (28.7%), rapid urease test (22.3%), cytology/histology (26.2% of cases) prevailed in the assessment of eradication rate. Standard triple therapy, including proton pump inhibitor, clarithromycin and amoxicillin was most commonly prescribed as first-line therapy (64.6% of cases). The duration of eradication therapy was 14 days in the majority of cases with pantoprazole as the most common proton pump inhibitor in standard triple therapy regimens (84.8%). The efficacy of 14-day standard triple therapy (mITT) was 87.0%. Conclusion. The results indicate a high frequency of non-invasive methods use for assessing the effectiveness of eradication therapy; however, the overall rate of eradication efficacy assessment is low, limiting the possibility of analyzing the eradication results. The effectiveness of the most common 14-day standard triple first-line therapy in Kazan doesnt reach the recommended 90% eradication level. This could be explained by high rate of pantoprazole use, which is not an optimal proton pump inhibitor in eradication therapy regimens.

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].
