Campylobacter pylori associated gastritis in patients with rheumatoid arthritis taking nonsteroidal anti-inflammatory drugs

Abstract

Fifty-two patients with rheumatoid arthritis taking nonsteroidal anti-inflammatory drugs were studied in order to assess the carriage rate of Campylobacter pylori (C. pylori) with reference to dyspeptic symptoms, endoscopic appearance and antral histology. All patients were interviewed using a standard gastrointestinal symptom scoring questionnaire and underwent endoscopy at which two antral biopsies were obtained. Sections were examined for the presence and severity of gastritis and of C. pylori. Forty-four of 52 patients (85%) had histological evidence of gastritis. Twenty-six of 44 (59%) patients with gastritis were positive for C. pylori. Twenty-six of 28 patients with 'active' (polymorph infiltration) chronic gastritis were positive for C. pylori (p less than 0.002). Sixteen of 26 bacteria-positive patients had gastrointestinal symptoms compared with eight of 26 bacteria-negative patients (p less than 0.05) and this may have therapeutic implications. There was no correlation between the presence of organisms and the appearances at endoscopy.
