Aim: To determine the prevalence of non-Helicobacter pylori (H pylori)-related duodenal ulcer in patients with acid-peptic diseases. Methods: Medical records of patients who attended the Gastroenterology Department at Aga Khan University Hospital from 1999 to 2001 and had endoscopic diagnosis of duodenal ulcers were reviewed. Duodenal ulcer associated with H pylori was diagnosed on the basis of endoscopy, rapid urease test and histopathology whereas histories of aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs) related duodenal ulcers. Non-H pylori, non-NSAID duodenal ulcers were those without H pylori infection and history of NSATD intake. Co-morbid conditions associated were noted. Results: Of 2 260 patients, 10% (217/2 260) had duodenal ulcer. Duodenal ulcer related to H pylori infection accounted for 53% (116/217), NSAID-related 10% (22/217), non-H pylori non-NSAID 29% (62/217), and 8% (17/217) had both H pylori infection and histories of NSAID intake. Fifteen percent (18/116) patients had past histories of peptic ulcer disease in H pylori infection, while 8% (5/62) in non-H pylori non-NSAID ulcer. Co-morbid conditions in H pylori infection were seen in 23% (27/116) and 34% (21/62) in non-H pylori non-NSAID ulcer. Conclusion: Incidence of H pylori infection related with duodenal ulcer is common. In the presence of co-morbids, non-H pylori and non-NSAID duodenal ulcer is likely to be present.
