Introduction: Upper gastrointestinal bleeding continues to be a severe and frequent complication in ulcerative disease. Etiologic diagnosis in these patients is highly important in order to initiate appropriate treatment and prevent bleeding recurrence.
Objective: 1. To investigate the prevalence of Helicobacter pylori infection and use of NSAIDs in patients with upper gastrointestinal hemorrhage of peptic origin. 2. To analyze the strategy used for the diagnosis of H. pylori in our previous work. PATIENTS AND MEHTODS: Seventy-three patients with endoscopically-diagnosed upper gastrointestinal bleeding of peptic origin were included in the study. The use of NSAIDs was investigated. H. pylori infection was diagnosed if one of the following tests was positive: urease test, histology, breath test.
Results: H. pylori infection was found in 92% of duodenal ulcers and in 88% of gastric ulcers. Fifty-six percent of the patients had taken NSAIDs. Excluding these patients resulted in an H. pylori infection rate of 96.7%. The diagnosis was based on urease test in 46%. In the remaining patients, breath test and histology were required.
Conclusions: The main etiology in patients with upper gastrointestinal bleeding of peptic origin is H. pylori infection followed by the use of NSAIDs, and these two factors frequently coexist. The strategy of performing a urease test and, when this is negative, performing histological study and a breath test, is valid and allows a diagnosis of H. pylori infection to be made even if patients are receiving treatment that could make diagnosis difficult.
