Chronic atrophic gastritis and Helicobacter pylori infection in primary biliary cirrhosis: a cross-sectional study with matching.

Abstract

PBC patients are not characterized by chronic atrophic gastritis. Even though they present chronic gastritis with the same prevalence as dyspeptic controls, and show signs of previous H. pylori infection as frequently as dyspeptic patients, they are actually much less frequently infected. The reasons for this observation are unclear.
