High prevalence of duodenal ulcer in a tertiary care hospital in the city of São Paulo, SP, Brazil
CONTEXT: In spite of Helicobacter pylori infection being the etiological cause of peptic ulcer and its high prevalence in Brazil, the prevalence of peptic ulcer disease has been poorly studied. OBJECTIVES: To verify the peptic ulcer disease prevalence in patients of a tertiary care hospital. METHODS: Diagnostic findings from 1,478 consecutive endoscopies were correlated with the urease test results for H. pylori infection diagnosis and demographic data in a total of 3,779 endoscopies performed in 2005. The mean age of the patients was 51.14 ± 16.46, being 613 (41.5%) men. RESULTS: Peptic ulcer was diagnosed in 494 (33.4%) patients with a mean age of 54.86 ± 14.53, 205 (52%) were men, being 391 (26.5%) duodenal ulcer and 103 (7%) gastric ulcer. Normal endoscopy was found in 272 (18.4%) patients with a mean age of 38.4 ± 15.22, being 49 (18%) men. The comparison of peptic ulcer group with the patients that had normal endoscopy revealed that H. pylori infection [P = 0.005; OR = 1.70; 95% CI = 1.17-2.47][ign], male gender [P<0.0001; OR = 5.53; 95%CI = 3.67-8.34][ign] and older age [P<0.0001; OR = 1.08; 95%CI = 1.06-1.09] increased the risk of peptic ulcers. The overall H. pylori prevalence was 53% (786). CONCLUSIONS: Prevalence of duodenal ulcer is high in a Brazilian population that had H. pylori infection associated with older age and male gender as important determinants to gastrointestinal diseases outcome. Future prospective studies should confirm these findings.
