Helicobacter pylori-associated gastritis: does it play a role in functional dyspepsia?
OBJECTIVE
The goal of this study is to averiguate whether Helicobacter pylori (Hp)-associated gastritis is involved in the etiology of functional dyspepsia (FD) or, at least in a subset of these patients.


METHODS
103 consecutive FD patients were prospectively analyzed and subdivided according to their main complaints into ulcer-like FD (n = 31), dysmotility-like FD (n = 24) or nonspecific FD (n = 48). After endoscopy with gastric biopsy, gastritis and Hp infection were assessed and graded by histology according to the Sydney System. The prevalence of gastritis, Hp and disease activity were analyzed among the three FD subtypes and against 42 age, sex and race matched controls.


RESULTS
Hp was identified in 64 (62%) of the FD group and in 23 (55%) of the controls (p > 0.20, NS). We neither observed any increased prevalence of the infection among FD subgroups (dysmotility-like 58%, ulcer-like 58%, unspecified 67%), nor in the activity of gastritis among FD subgroups and controls. We conclude that Helicobacter pylori gastritis per se is not associated with functional dyspepsia.
