重蹇譬科大星 (2)Helicobacter-associated chronic gastritis Histologically,helicobacter-associated gastritis affects the entire stomach but to a variable degree.The majority of patients exhibit diffuse involvement of the antrum and body with the gradual acquisition over time of glandular atrophy,replacement fibrosis and intestinal metaplasia. Patients with this distribution of gastritis are at an increased risk of gastric ulcer and carcinoma than uninfected individuals
