Conditions

Helicobacter Pylori Infection

Brief summary

Helicobacter pylori (H Pylori) infection is associated with functional dyspepsia, peptic ulcer disease, atrophy and gastric cancer. The bacterium has been classified as grade I carcinogen by the WHO in 1994(1). Based on the clinical and microbiological data it is now well known to be the strongest risk factor for developing intestinal type and diffuse type of adenocarcinoma(2-4). While testing and treating asymptomatic persons is a grey area, it is now recommended to rule out H. pylori in un-investigated dyspepsia patients (5-7), and if detected, it must be treated. However, worldwide and especially in the Asian countries, we face a widespread problem of antibiotic resistance(8,9). Regimens are typically selected based on the varying regional clarithromycin resistance(6,9). There is a need for an efficient and reliable empirical therapy that can be universal, has maximal eradication rates irrespective of resistance patterns, has good compliance and minimal adverse events without the emergence of superbugs. We also need a reliable rescue therapy for H. pylori eradication failure.

Interventions

DRUGVonoprazan 20mg, Esomeprazole 40 mg, Amoxicillin 1 g, Clarithromycin 500 mg

Participants will receive the respective drug regimens twice daily. The Vonoprazan triple therapy arm will administer Vonoprazan 20 mg, Amoxicillin 1 g, and Clarithromycin 500 mg twice daily. The Standard triple therapy arm will administer Esomeprazole 40 mg, Amoxicillin 1 g, and Clarithromycin 500 mg twice daily.
