    Abstract:
    OBJECTIVE: Prostaglandins regulate gastric motor function. Inhibition of prostaglandins by nonsteroidal antiinflammatory drugs (NSAIDs) may alter gastric emptying. To study gastric emptying of solids and its relation to endoscopic findings and Helicobacter pylori in patients receiving long-term NSAIDs, we undertook this study. METHODS: Ninety-five patients with arthritis, 65 taking long-term NSAIDs (Group I) and 30 not taking NSAIDs (Group II) were studied. Presence of dyspeptic symptoms was determined using a questionnaire. Mucosal damage was determined by endoscopy. H. pylori was detected by antral biopsies for rapid urease test and histology. Gastric emptying for solids was evaluated using a scintigraphic method. Thirty healthy volunteers were used as controls for gastric emptying (Group III). Patients with peptic ulcer were excluded from the analysis of gastric emptying. Logistic regression analysis was performed to identify predictive factors for gastric emptying. RESULTS: Nineteen patients from Group I with peptic ulcers were excluded. Dyspeptic symptoms were seen in 24 (52%) Group I and seven (23%) Group II patients. Gastroduodenal erosions were seen in 10 (21.7%) Group I patients and four (13.3%) Group II patients. H. pylori was detected in 17 patients in Group I (36.9%) and Group II (56.6%). Gastric emptying was delayed in 24 (52%) Group I patients, six (20%) Group II patients (p < 0.001), and in none of the Group III controls. The mean gastric emptying times were 99.5 (15.6) min and 89 (17.7) min for Groups I and II, respectively (p < 0.05). Endoscopic damage was found with similar frequency in Group I patients with delayed or normal gastric emptying. H. pylori infection was present in 37.5% Group I patients with delayed gastric emptying and in 36.3% with normal gastric emptying (p = ns). Logistic regression analysis identified NSAID therapy as the single factor most predictive of delayed gastric emptying. CONCLUSION: Delayed gastric emptying was seen in 52% of patients on long-term NSAID therapy.
