Proton pump inhibitor treatment decreases the incidence of upper gastrointestinal disorders in elderly Japanese patients treated with NSAIDs.

OBJECTIVE The Japanese health insurance system approved the use of proton pump inhibitors (PPIs) for the prevention of peptic ulcers in patients using low-dose aspirin (LDA) and/or non-steroidal anti-inflammatory drugs (NSAIDs). However, many orthopedists and physicians do not prescribe PPIs to elderly patients with atrophic gastritis. The aim of this study was to determine whether PPIs are effective in preventing gastrointestinal mucosal injury in elderly Japanese patients with atrophic gastritis. METHODS We examined the associations between the use of antiulcer drugs and endoscopic findings in elderly Japanese patients using LDA or NSAIDs. Patients We evaluated 100 patients using LDA and 58 patients using non-aspirin NSAIDs 65 years of age or older. All patients underwent upper GI endoscopy to detect the presence of open ulcers and hemorrhagic lesions and assess the extent of atrophic gastritis. RESULTS Among the patients using LDA, the prevalence of open ulcers was significantly lower in the patients using PPIs than in those using mucosal protective agent only and those not receiving antiulcer treatment (p<0.001). Among the patients using NSAIDs, the patients treated with PPIs exhibited a significantly lower incidence of open ulcers than the patients not receiving antiulcer treatment (p=0.012). Open-type atrophic gastritis was observed in nearly 70% of the patients. CONCLUSION The use of PPI treatment is advisable in order to prevent the discontinuation of LDA or NSAIDs due to the development of gastrointestinal disorders in elderly patients with atrophic gastritis.
