[Quadruple treatment with doxycycline, furazolidone, bismuth and proton pump inhibitor is still effective against Helicobacter pylori in our population].

Our objective is to determine the effectiveness of a therapeutic regimen for helicobacter pylori that includes a proton pump inhibitor, doxycycline, furazolidone and bismuth in our location. We carried out a retrospective study, non-randomized, in a private hospital in Lima, Peru. Patients with biopsy and/or rapid urease test proven helicobacter pylori infection after an endoscopy, from January 2017 to October 2022 were included.
