  • Title: When does gastric atrophy develop in Japanese children?
    Author: Kato S, Kikuchi S, Nakajima S.
    Journal: Helicobacter; 2008 Aug; 13(4):278-81. PubMed ID: 18665937.
    Abstract:
    BACKGROUND: Long-term Helicobacter pylori infection causes inflammatory sequelae such as atrophy and intestinal metaplasia in the stomach, which is thought to increase the risk of developing gastric malignancy. We previously reported that gastric atrophy can develop in Japanese children with H. pylori infection, predominantly in the antrum. However, detailed data about the age of children with atrophy are largely lacking. METHODS AND RESULTS: In the present study, 131 children (79 boys) with H. pylori infection were re-analyzed for an association between age and the grade of gastric atrophy. The gastric antrum was histologically evaluated in all 131 patients and the corpus in 46 patients. Grade 2 and 3 antral atrophy was observed in 13 and one patients, respectively: the mean age was 12.1 years. Two patients (11 and 14 years old) had grade 2 corpus atrophy but no patients had grade 3. No significant difference was found in age among patients with grade 0, 1 and 2 or 3 atrophy in the antrum (p = .97) and in the corpus (p = .59). None of the patients with grade 2 or 3 atrophy had intestinal metaplasia either in the antrum or in the corpus. CONCLUSIONS: The results of the present study require a careful interpretation because of the retrospective analysis. In high-risk countries of gastric cancer, however, eradicating H. pylori in childhood could prove more effective in preventing gastric atrophy, ultimately, the development of cancer.
