Abstract
BACKGROUND: It is not yet clear whether lymphocytic gastritis might not be a sequela of Helicobacter pylori (Hp) infection. The aim of the present pilot study was, therefore, to investigate whether lymphocytic gastritis can be cured by Hp eradication, which, if affirmed, would provide indirect evidence for an etiopathogenic relationship. PATIENTS AND METHODS: 98 of 220 patients with lymphocytic gastritis diagnosed between 1988 and 1998 were investigated at least twice, with 61 of them undergoing Hp eradication treatment. In 29 of these patients, the pretreatment histological work-up using the Warthin-Starry silver stain revealed Hp colonisation, while in the remaining 32 patients the biopsies from the antrum and corpus were negative for Hp. The other 37 patients received no treatment, and served as a control group. RESULTS: Both in the group with Hp-positive, and in the group with Hp-negative histology prior to treatment, eradication treatment led to healing of the gastritis, i.e. to regression of the gastritis parameters including normalisation of the intra-epithelial lymphocyte count, in 93.1% and 84.3% of the cases, respectively. In the control group the histological findings did not change. CONCLUSIONS: The results of our retrospective study support the notion that most cases of lymphocytic gastritis might be a consequence of Hp infection. This, however, needs to be clarified definitively by a prospective, randomized, double-blind study. Copyright 2001 S. Karger AG, Basel
