Role of aging in the expression of Helicobacter pylori gastritis in the antrum, corpus, and cardia.
BACKGROUND
Earlier studies identified a pylorocardial expansion of chronic gastritis. We investigated the age-dependent changes in grading and topography of Helicobacter pylori gastritis.


METHODS
Antral, corpus, and cardial biopsy specimens from 216 H. pylori-positive patients with no peptic ulcer disease (PUD), malignancy, or Barrett's oesophagus were evaluated with haematoxylin and eosin and modified Giemsa. The patients were separated into four equal-sized age groups (1, < 46 years; II, 46-56 years; III, 57-68 years; IV, > 69 years). Sydney-system gradings of bacterial density and activity and degree of gastritis were used to calculate gastritis sum scores for age- and biopsy site-dependent comparisons. The prevalence of intestinal metaplasia (IM) and atrophy was also compared.


RESULTS
Mean antral sum scores decreased slightly in group IV but were higher than those in the corpus or cardia in all groups (P < 0.05 each). In the corpus mean scores increased in groups II-IV versus group I (P < 0.05 each), and aging was associated with a significant increase in bacterial density and active inflammation. The cardia scores remained virtually constant in all groups and exceeded significantly that in the corpus in group I. IM and atrophy increased with age, occurring more frequently and earlier in the antrum and cardia than in the corpus.


CONCLUSIONS
Progression of gastritis with age involves the corpus but not the cardia. Antral inflammation decreases slightly in patients of advanced age.
