Abstract

Objective: To identify demographic and endoscopic characteristics of patients with Helicobacter pylori positive and negative chronic peptic ulcer disease.

Design: Cross-sectional study of peptic ulcer disease in prospectively recruited PATIENTS undergoing gastroscopy.

Patients: 277 consecutive patients referred for gastroscopy in 1996-1998.

Main outcome measures: Rapid urease test, culture and histological examination for H. pylori infection; anti-H. pylori IgG antibodies in serum; demographic data, intake of non-steroidal anti-inflammatory drugs (NSAIDs) in the preceding 3 months, and size, number and location of ulcers.

Results: 54 patients (19%) had evidence of peptic ulcer disease (34 gastric ulcer, 14 duodenal ulcer and 6 both gastric and duodenal ulcer); 45 had active chronic peptic ulcer disease and were analysed in detail. H. pylori was present in 25 (56%) of these patients; 10 (22%) had used NSAIDs and 7 of the NSAID group also had H. pylori infection. Of the patients with gastric ulcers, those with non-H. pylori, non-NSAID ulcers were significantly younger than both those with H. pylori-associated ulcers (mean age, 48 v. 65 years, P = 0.02) and those with NSAID-associated ulcers (mean age, 48 v 68 years, P = 0.02). The average size and number of gastric ulcers did not differ between patients with and without H. pylori infection. Of patients with duodenal ulcers, those with H. pylori infection had significantly fewer ulcers (1.1 v. 1.8, P = 0.04), although ulcer size was similar in the infected and uninfected groups.

Conclusions: Gastric ulcers may now be more common than duodenal ulcers. Gastric ulcers associated with H. pylori infection and/or NSAID use occurred mostly in older people, while non-H. pylori, non-NSAID gastric ulcers were more common in younger patients. In the duodenum, single ulcers were associated with H. pylori infection, and multiple ulcers were more frequent in the non-H. pylori, non-NSAID group.
