Bismuth quadruple therapy (BQT) is an effective treatment for Helicobacter pylori infection. However, frequent dosing schedules of BQT regimen often compromise drug adherence and may affect treatment outcomes. This retrospective study aimed to investigate the efficacy of twice-daily BQT compared to that of four times a day therapy. From August 2018 to November 2020, adult patients who failed first-line standard triple therapy and underwent BQT were eligible. Patients were categorized into two groups according to dosing schedule: (i) the BQT group (n = 213) who received standard BQT administered four times a day; and (ii) the BQTb group (n = 141) who received proton pump inhibitor, bismuth 600 mg, metronidazole 500 mg, and tetracycline 1 g twice a day. The eradication rate did not differ between the BQT (92.5%) and the BQTb groups (90.1%) (p = 0.441). Adherence and adverse event rate were similar between the two groups. Multivariate analysis showed that current smoking was associated with eradication failure; however, dosing frequency was not associated with the efficacy of eradication therapy. This study suggested that twice a day BQT is as effective as four times a day therapy for second-line treatment of H. pylori infection.

Background Aims: Most patients with Helicobacter pylori infection are consulted for the first time by family physicians. We aimed to survey the adherence to the newest guidelines of the management of H. pylori infection in the primary and secondary care settings in Hungary. Methods: From a total of 793 physicians, 94 trainees in family medicine, 334 family physicians without and 195 with board certification in internal medicine, 87 internists, 78 family paediatricians were invited to take part in the study. Diagnostic and therapeutic attitudes towards H. pylori infection were compared by a voluntary and anonymous questionnaire. Results: Participants test for H. pylori infection in 92.8% of cases with a family history of peptic ulcer or 76.9% of gastric cancer, 68.9% of dyspepsia and 49.9% of non-specific abdominal complaints, before initiation of non-steroidal anti-inflammatory drug (NSAID; 17.3%) and antiplatelet treatment (14.5%), respectively. They confirm the success of eradication therapy in 88.1% mainly by urea breath test. Most of them initiate eradication therapy by themselves and only 22.4% refer their patients to a gastroenterologist. Clarithromycin-based standard triple therapy is the most preferred (62.1%) and only 3.7% choose quadruple combination with bismuth as first-line and 48.1% as second-line therapy. We found significant differences between groups with respect to the physicians’ own infection, localization of practice, and sources of information on H. pylori infection. Internists are more likely to clarify H. pylori status before the initiation of NSAID and antiplatelet therapies, initiate second-line therapies and use bismuth compared to the other groups. Family physicians with board certification in internal medicine are also prone to start eradication therapy and less prone to refer patients to a gastroenterologist. Family paediatricians prefer stool antigen determination, screen family members and prefer gastroenterologist consultation more often, and use bismuth less frequently than the other groups. Family physicians with previous infection check for H. pyloriinfection more frequently before the initiation of NSAID treatment and are more likely to use histology to detect H. pylori. Postgraduate trainings were the most popular source of information. Conclusion: The adherence to the recent recommendations of current guidelines is moderate. There is a need to increase adherence to current recommendations by family physicians and internists.
