    INTRODUCTION: The proportion of clinically significant endoscopic findings (CSEF) in dyspepsia affects the initial management of this condition. With the changing epidemiology of organic upper gastrointestinal diseases in Asia, current data on CSEF remains uncertain.

    METHODS: A cross-sectional study of consecutive adult patients attending an open access endoscopy list for the primary indication of dyspepsia was conducted. Independent epidemiological and clinical factors for CSEF were determined prospectively.

    RESULTS: Data for 1167/1208 (96.6 %) adults (mean age 49.7 ± 15.9 years, 42.4 % males, ethnic distribution: 30.5 % Malays, 36.9 % Chinese and 30.8 % Indians) were analysed between January 2007 and August 2008. Three-hundred and eight (26.4 %) patients were found to have CSEF, most often those with age ≥45 years (30.3 vs 19 %, P < 0.0001), male gender (34.1 vs 20.7 % female, P < 0.0001), lower education levels (i.e. primary or no education), smoking (36.7 vs 24.9 %, P = 0.003), H. pylori infection (40.6 vs 21.8 %, P < 0.0001), and duration of dyspepsia ≤5 months (32.8 vs 24.4 %, P = 0.006). Age ≥ 45 years (OR 1.82, 95 % CI = 1.38-2.48), male gender (OR 1.84, 95 % CI = 1.53-2.59), H. pylori infection (OR 2.36, 95 % CI = 1.83-3.26), and duration of dyspepsia ≤5 months (OR 1.44, 95 % CI = 1.13-2.03) were subsequently identified as independent risk factors for CSEF.

    CONCLUSION: CSEF are found in 26.4 % of Asian adults with uninvestigated dyspepsia. Duration of symptoms <5 months, among other recognised factors, is predictive of CSEF.

    A study was undertaken to determine the role of Helicobacter pylori in non-ulcer dyspepsia (NUD) and to determine the efficacy of colloidal bismuth subcitrate (CBS) in the treatment of NUD. Seventy-one patients were randomly allocated (double blind) to CBS or placebo, two tablets twice daily for 4 weeks. The severity of dyspepsia was scored and endoscopies performed before and after treatment, and antral biopsy specimens were taken for bacteriologic and histologic examination. Forty patients had H. pylori infection, and all had changes of chronic active gastritis. H. pylori was cleared from 17 to 21 patients (81%) treated with CBS, whereas none of the 19 patients treated with placebo cleared the bacteria. Improvement in histology was noted in 15 of 21 patients (71.4%) treated with CBS, whereas no improvement was noted in any of the placebo controls. Thirty-one patients were negative for H. pylori. All had either normal gastric histology or minor degrees of inflammation. Seventeen of these patients received CBS, and 14 received placebo. All groups reported improvement in the symptom score; however, the H. pylori-positive, CBS-treated group recorded a significantly higher improvement than the other groups (p less than 0.001). Relapse of H. pylori infection after initial clearance of the bacteria was high. Twelve of 16 patients evaluated relapsed 1 month after withdrawal of CBS.

    Although well established in the West, stool antigen tests (SAT) are not widely used in Asia. Data on the accuracy of this test in Asia is sparse and, to date, there have been no studies looking at the more refined monoclonal SAT. The aim of this study is to validate the diagnostic accuracy of a stool antigen test, Hp STAR, for the detection of Helicobacter pylori.
