It usually arises in a stomach with corpus predominant or pangastritis that has undergone extensive atrophy and intestinal metaplasia. We hypothesised that a Japanese population would have a more severe gastritis with a corpus predominant or pangastritis pattern and a greater degree of atrophy and intestinal metaplasia than that found in the UK. To test this we designed a comparative trial.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    A total of 252 age matched consecutive patients were recruited from the endoscopy services in Leeds and Tokyo. In each centre, 21 patients were prospectively selected from each decennial, between the ages of 20\u201380 years. All had epigastric discomfort as their predominant symptom. Patients with peptic ulcer, cancer, and oesophagitis were excluded. Five gastric biopsies were examined by two histopathologists using the updated Sydney system.\n                    <jats:italic>Helicobacter pylori<\/jats:italic>\n                    infection was assessed by histology and culture of biopsies and enzyme linked immunosorbent assay and immunoblot of plasma.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Gastritis was found by both pathologists in 59 (47%) UK and 76 (60%) Japanese patients (\u03c7\n                    <jats:sup>2<\/jats:sup>\n                    test, p\u200a=\u200a0.04). In those patients with gastritis, corpus predominant or pangastritis was commoner in the Japanese (63% Japan\n                    <jats:italic>v<\/jats:italic>\n                    36% in the UK (\u03c7\n                    <jats:sup>2<\/jats:sup>\n                    test, p\u200a=\u200a0.003) Atrophy and intestinal metaplasia were more extensive and severe (Mann-Whitney U test, p&lt;0.001) and chronic inflammation and polymorph activity were also greater, especially in the corpus (Mann-Whitney U test, p&lt;0.001).
