Abstract
AIM-Atrophy and intestinal metaplasia (IM) as precancerous conditions consistently begin in the antrum and are most severe along the lesser curvature. The aim of this study was to investigate discrepancies in the prevalence, the severity of atrophy, and IM in antral mucosa of Helicobacter pylori infected gastritis and difference in age of onset among Chinese and Dutch patients. METHODS-Two hundred and sixty five Chinese patients and 261 Dutch patients with H pylori infection were enrolled. The degrees of atrophy and IM were graded according to the updated Sydney system. RESULTS-The overall prevalences of atrophy and IM were lower in Dutch patients (42% and 26%, respectively) than in Chinese patients (52% and 32%, respectively). Only the difference in atrophy reached significance (p = 0.028). However, in both Chinese and Dutch patients, the degrees of atrophy and IM were low and severe degrees were rare. The mean ages of Chinese and Dutch patients with atrophy and IM were higher than those without atrophy and IM (with atrophy (Chinese patients): mean, 42.12; SD, 9.80; with IM (Chinese patients): mean, 42.56; SD, 9.96; with atrophy (Dutch patients): mean, 55.16; SD, 12.20; with IM (Dutch patients): mean, 57.79; SD, 11.13; without...Continue Reading
