The studies report conflicting findings about the effect of H. pylori infection on NSAID-related ulcers, and proton-pump inhibitors (PPIs) seem to be superior to eradication only to prevent recurrent ulcer bleeding with LDA.
We hypothesised that a cyclooxygenase-2-selective NSAID plus proton-pump inhibitor is superior to a non-selective NSAID plus proton-pump inhibitor for prevention of recurrent ulcer bleeding in concomitant users of aspirin with previous ulcer bleeding.
