    Abstract:
    BACKGROUND & AIMS: Fundic gland polyps (FGPs), the most common type of gastric polyps, have been associated with prolonged proton pump inhibitor therapy and an increased risk of colon cancer. The presence of FGPs has been inversely correlated with Helicobacter pylori infection. We evaluated the prevalence of H pylori-associated gastritis, colonic polyps, and carcinomas in subjects with and without FGPs. METHODS: We analyzed data collected from community-based endoscopy centers in 36 states (plus Washington DC and Puerto Rico) on patients who underwent esophagogastroduodenoscopy (EGD) and colonoscopy between April 2007 and March 2008. Of the 103,385 patients who underwent EGD during this time period, gastric biopsy samples were collected from 78,801 and colonic biopsies from 26,017. Slides of samples from Helicobacter-infected FGPs and FGPs with dysplasia were reviewed. RESULTS: FGPs were detected in 6081 patients (67.8% women). Helicobacter infection was present in less than 0.5% patients with FGPs and 13.0% of those without FGPs (odds ratio [OR], 29.05; 95% confidence interval [CI], 20.4-41.4; P < .0001). Colonic adenomas were detected in 42.3% of women with FGPs and 33.8% of those without (OR, 1.43; 95% CI, 1.26-1.63; P < .001); there was no significant difference in colonic adenomas between men with and without FGPs. CONCLUSIONS: Women had a higher prevalence of FGPs. FGPs were associated with gastroesophageal reflux disease symptoms, gastric heterotopia, hyperplastic colonic polyps (only in men), and colonic adenomas (only in women, especially those over 60 years of age). The presence of FGPs was inversely correlated with H pylori infection, active gastritis, and gastric neoplasia.
