Helicobacter pylori and bleeding duodenal ulcer: prevalence of the infection and role of non-steroidal anti-inflammatory drugs.
Several authors have reported low prevalence of Helicobacter pylori infection in patients with upper gastrointestinal bleeding (UGIB). Our aim was to study the prevalence of H. pylori in bleeding duodenal ulcer (DU), with both invasive and non-invasive methods, and to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs). ⋯ The most important factor associated with H. pylori-negative bleeding DU is NSAID use, and if this factor is excluded prevalence of infection is almost 100% (97%), similar to that found in patients with non-bleeding DU (and without NSAID intake). Bleeding DU patients with neither H. pylori infection nor NSAID use are extremely rare (only 2%), which suggests that the pathogenesis of bleeding DU is similar to that of non-complicated DU disease.
