Lymphoid hyperplasia is endoscopically observed as multiple small whitish round nodules or spots. This retrospective study was performed to examine the prevalence of that finding in patients with Barrett's epithelium and its relationship with the status of H. pylori infection.The study subjects were 3353 patients (males 2186, females 1167; mean age 55.2 ± 9.4 years) in whom the status of H. pylori infection had been determined. The presence of Barrett's epithelium ≥ 5 mm in length was endoscopically determined, and then endoscopic observations with blue laser imaging were used to investigate the presence of lymphoid hyperplasia in those areas.Barrett's epithelium was diagnosed in 1884 (56.2%) of the subjects, and endoscopic findings of lymphoid hyperplasia were observed in 402 (21.3%) of those with Barrett's epithelium. Lymphoid hyperplasia in Barrett's epithelium was not present in any without a current or prior H. pylori infection, while the prevalence of lymphoid hyperplasia in H. pylori-positive and post-eradicated subjects was 48.4% and 30.4%, respectively (p < 0.001). Multiple logistic regression analysis revealed that female gender, younger age, and higher degree of gastric mucosal atrophy were significant factors related to lymphoid hyperplasia positivity. In addition, the duration after H. pylori eradication was negatively correlated with its prevalence.Endoscopic findings of cardiac lymphoid hyperplasia were well correlated with H. pylori infection, although prevalence decreased over time following bacterial eradication.© 2021 The Authors.
