Helicobacter pylori infection and erosive gastritis.

ABSTRACT

One hundred and eleven patients were included in the study. Thirty seven had erosive gastritis, thirty four chronic gastritis and forty were controls without any gastrointestinal diseases confirmed by symptoms and upper gastrointestinal endoscopy. Patients with erosive gastritis were divided into non-steroidal anti-inflammatory drug (NSAID) users and non-users. H pylori status was determined by urease test, serology and/or histology. The prevalence of H pylori was compared between the various groups. The prevalence of H pylori infection in erosive gastritis, chronic gastritis and controls was 68%, 76% and 65%, respectively, the difference was not significant (P > 0.05), 8 out of 11 patients with erosive gastritis and NSAID use (73%) were positive for H pylori. Likewise 17/26 patients with erosive gastritis without NSAID use (65%) were positive for H pylori (P > 0.05). Body of the stomach (65%) was the commonest site for erosions compared to antrum (43%) or fundus (27%) (P < 0.02). H pylori infection does not predispose to erosive gastritis. NSAID use does not affect H pylori prevalence. Routine H pylori eradication is, therefore, not indicated in patients with erosive gastritis infection. Body of the stomach is the most predominant site for erosions.
