Study Description

Patients who present to the outpatient gastroenterology clinic at our institution with a positive diagnostic test for H pylori will be screened. Included patients will undergo randomisation into 3 groups. Randomization will be performed by a random sequence generator to create equal sized groups in boxes of 12.

Group 1-amoxicillin 1000mg bd and rifabutin 150 mg bd and esomeprazole 40 mg bd Group 2- amoxicillin 1000mg bd and rifabutin 150 mg d and esomeprazole 40 mg bd Group 3- standard of care Standard of care in previously untreated patients will consist of concomitant treatment (amoxicillin 1000mg, clarithromycin 500 mg, tinidazole 500 mg and esomeprazole all given twice daily for 14 days). In previously treated patients standard of care will consist of bismuth quadruple therapy, quinolone based therapy, or other susceptibility guided treatment where available.

Treatment duration will be 14 days in all groups. Patients who are randomised to Group 3 and fail treatment will be offered open label rescue treatment with amoxicillin 1000mg bd, rifabutin 150 mg bd and esomeprazole 40 mg bd (14 days).
