Background:
The pathogenic role of Helicobacter pylori (H. pylori) infection in the setting of NSAID use is still controversial. Aim of the study is to prove increased incidence of gastric mucosa damage in H. pylori positive NSAID users compared to H. pylori negative patients.
Methods:
Patients with dyspeptic symptoms (n = 160, average age 62.13 +/- 6.24, ranged from 51 to 77 years) were divided in two groups: 80 patients (45 male, 35 female) with positive history of using NSAID and same group with negative history for NSAID. All patients underwent endoscopy, examined to H. pylori presence by rapid unease test. Patients with ulcer or erosions (> 5) were evaluated and grade of gastric mucosa damage were done according to Forrest classification of gastrointestinal bleeding.
Results:
In first group 69/80 of examined patients were H. pylori positive, in second group 56/80 were H. pylori positive (X2 = 5.266; p = 0.022). In gastric mucosa bleeding, caused with NSAIDs, H. pylori was not diagnosed more often compared to other group (p > 0.05).
Conclusion:
Patients with NSAID induced gastric injury were significantly greater incidence of H. pylori infection compared to patients without history of NSAIDs abuse. H. pylori was not significantly present in complication of ulcer disease (bleeding) caused by NSAID.
