Semeya et al. (2026) reported that persistent Helicobacter pylori infection after eradication was associated with higher risk of peptic ulcer bleeding (PUB) than successful eradication in chronic aspirin users, with PUB prevalence of 8.7% at 6 weeks and 11.9% at 6 months with persistent infection versus 1.5% at 6 weeks and 3.7% at 6 months with successful eradication (P < 0.001).
