Abstract
We designed a race-conscious study to assess the presence of Helicobacter pylori (Hp) virulence factor cagA in a retrospective cohort of patients with active Hp infection. We compared cagA status by race in gastric tissue samples from 473 patients diagnosed with active Hp infection from 2015-2019. Hp+ Black patients were two times more likely to be cagA+ than Hp+ White patients (82% vs. 36%, P < .0001). Presence of cagA is common among endoscopy patients with active Hp infection; appropriate testing and treatment of Hp can both reduce gastric cancer risk and address health disparities.
