Infection with Helicobacter pylori and long-term use of non-steroidal antiinflammatory drugs

The use of nonsteroidal anti inflammatory drugs (NSAID) is associated with an increased risk of peptic ulcer and of ulcer complications. However, the relation between Helicobacter pylori infection and gastroduodenal damage associated with NSAID use is unclear. This study investigated the prevalence of Helicobacter pylori infection in patients with arthritis (n = 85) taking NSAID, trying to find out whether the patients taking NSAID and infected with H. pylori were more likely to have dyspepsia, mucosal damage or chronic active gastritis than those without H. pylori infection. H. pylori was identified by biopsy, rapid urease test and histologic test. Dispeptic symptoms were assessed according to a standardized questionnaire. Gastroduodenal mucosal damage was graded endoscopically (using a modified Lanza scale) and the diagnosis of chronic gastritis was based on the histologic criteria of the Sydney system. The frequency of H. pylori infection was found to increase with age. No statistically significant difference was observed in the presence of damage to gastroduodenal mucosa between the patients with and without H. pylori infection. H. pylori infection was found to be associated with an increased frequency and severity of dyspeptic symptoms in patients with arthritis taking long-term NSAID. Chronic active gastritis was only present in patients with H. pylori infection. H. pylori infection was shown to be associated with an increased frequency and severity of dyspeptic symptoms in patients with arthritis on long-term NSAID therapy, without causing an increased damage to gastroduodenal mucosa.
