1.   In both series, H pylori was associated with chronic active gastritis compared with its presence in the mucosa without active inflammation.

2.   H pylori was particularly associated with the presence of intestinal metaplasia in both series.

3.   H pylori was more associated with the intestinal type in earlier and later series than with the diffuse type but the differences were not significant.

4.   H pylori is classically associated with inflammation of the antrum but not exclusively so.

5.   H pylori is associated with gastritis and peptic ulcer and possibly with non-ulcer dyspepsia, so both patients may have had chronic infection.
