High prevalence of Helicobacter pylori infection and histologic gastritis in asymptomatic Hispanics.

Department of Medicine, University of Southern California School of Medicine, Los Angeles 90033.

ABSTRACT

In this study, we estimated the prevalence of Helicobacter pylori infection and histologic gastritis in 58 asymptomatic Hispanic adult volunteers (mean age, 41 years; 59% male) by endoscopic biopsy of the upper gastrointestinal tract. Forty-six subjects (79%) were found to harbor H. pylori in gastric biopsies, and all had histologic gastritis. Four other subjects were found to have gastritis in the absence of H. pylori. Similar prevalences of H. pylori and gastritis were noted in all age groups and also in American-born and immigrant Hispanics. Biopsy data and serologic studies of H. pylori antibodies correlated well. We conclude that H. pylori infection is an almost universal finding in the gastric mucosa of asymptomatic adult Hispanics, regardless of age. The clinical significance of these findings is unknown, but we speculate that H. pylori and its associated gastritis could have a role in the high incidence of gastric carcinoma in Hispanic populations.
