Further study details as provided by Technische Universität Dresden:

Primary Outcome Measures:
  • The primary objective is to assess the healing rate of
  • patients with lymphocytic gastritis irrespective of H. pylori status after treatment
  • with esomeprazole 20 mg twice daily for 2 weeks.

Secondary Outcome Measures:
  • Secondary objective of the study are to evaluate the grade and activity of gastritis before and after
  • treatment according to updated Sydney classification, to assess the clinical GI symptoms at baseline and after 3 months
  • and to evaluate influence of the H. pylori-Status

Estimated Enrollment: 40
Study Start Date: February 2007
Estimated Study Completion Date: December 2009
Detailed Description:
Recently, a placebo controlled trial of our group has shown that H. pylori eradication therapy consisting of omeprazole 20 mg bid, clarithromycin 500 mg bid, amoxicillin 1000 mg bid for seven days leads to a complete long-lasting resolution of lymphocytic gastritis in 96 % of patients. However, after 3 months we also found a healing rate of 50 % in patients who received omeprazole 20 mg bid and placebo antibiotics for seven days suggesting spontaneous remission or a potential PPI effect. Thus, we speculate that PPI therapy may have led to elimination of H. pylori and subsequently healing of lymphocytic gastritis in those patients with potentially minimal H. pylori colonization at baseline. For this reason we investigate whether a PPI treatment alone is able to heal patients with lymphocytic gastritis.
