Question number one

When treating patients with Helicobacter pylori infection who have previously been exposed to macrolides, which treatment approach does the American College of Gastroenterology (ACG) recommend?

  • Clarithromycin-based triple treatment is recommended.
  • A proton pump inhibitor (PPI) and amoxicillin are used to treat the infection.
  • Bismuth quadruple therapy is a kind of treatment.
  • Amoxicillin is used in a high-dose dual regimen.

Question number two

The presence of significant levels of antibiotic resistance, along with treatment failure, has rendered conventional first-line therapy for the treatment of Helicobacter pylori infections unsuitable in many areas.

  • Amoxicillin
  • Clarithromycin
  • Metronidazole
  • Tetracycline

Question number three

The patients in a recent Phase 3 trial evaluating three different first-line treatments for H. pylori infection were randomized to one of three treatments: vonoprazan with amoxicillin (dual P-CAB), vonoprazan with amoxicillin and clarithromycin (triple P-CAB), or lansoprazole with amoxicillin and clarithromycin (triple P-CAB) (triple lansoprazole). As opposed to lansoprazole, which of the following statements better characterizes the P-CAB regimens:

  • The effectiveness of dual P-CAB treatment was shown to be inferior to that of triple P-CAB therapy and triple lansoprazole therapy.
  • The use of triple lansoprazole was shown to be better to the use of dual P-CAB treatment.
  • Each of the P-CAB regimens was shown to be non-inferior to triple lansoprazole treatment.
  • The use of triple lansoprazole was shown to be superior to both P-CAB regimens.
