Low dose of aspirin is the main cause of gastro-duodenal ulcer. The best prevention is not definite particularly in patients without history of ulcer and infected by H. pylori.The aim of the study is to evaluate the gastric damage induced by aspirin in patients with H. pylori infection but who have any history of ulcer.

Primary Outcome Measures:
  • Measure: severity of the ulcerated gastric lesions induced by the aspirin [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To measure: percentage of patients having had at least an ulcer [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To measure: the average of the ranks of lesion in antrum and corpus. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To measure percentage of patients having had digestive clinical events [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To measure: the average of the ranks of severity of the hemorrhagic lesions and erosive lesions evaluated in antrum and corpus by two analogical scales of 150 mm [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To measure Percentage of patients having a hemorrhagic digestive of clinical expression or detected by the biological tests. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To measure : Elements of the histopathologic score of Sydney [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Detailed Description:

The aim of the study is to compare the protective effect of H. pylori eradication versus Pantoprazole versus placebo on the gastric damage induced by low dose of aspirin. Treatment are attributed by randomisation. Patients are followed for 6 months and gastric damage are evaluated by endoscopy at the end of this period.
