Abstract
Aim of the study: The main aim of the present study was to identify the patient with rheumatoid arthritis (RA) taking non-steroidal anti-inflammatory drugs (NSAIDs) at risk for peptic ulcer disease (PUD) and its life-threatening complications. Patients and methods: During a retrospective study in which more than 1000 patients were interviewed, current gastrointestinal (GI) complaints were of no use in detecting current PUD. Results: A history of PUD was an important predictor of current PUD, while the predictive value of serologic parameters, such as serum values of pepsinogen and antibodies to Helicobacter pylori, was disappointingly low. A prospective study in which 81 consecutive RA patients underwent a gastroscopy revealed 16% PUD; again a history of PUD was the most important predictive parameter. Since no study had been undertaken into the effects of a NSAID on intragastric pH we performed such a study, the main conclusion being that indomethacin does not influence the intragastric pH of RA patients. A placebo-controlled study of ranitidine 300 mg b.i.d. for the prevention of recurrent PUD in RA patients on NSAIDs is underway.
