The detection of Helicobater pylori and the relationship between clinical and histological presentation

Objective To evaluate the relationship between Helicobacter pylori (Hp) infection and pathohistological presentation of gastric and deuodenal mucosa.Methods The gastritis biopsies were taken through endoscopy from each gastric body,antrum and duodenum in 60 patients with gastritis and 22 patients with duodenal ulcer respectively for the examination of histology.Result The positive rate of Hp was nearly 100% in active chronic gastritis which was significantly higher than that of active duodenitis.The total detecting rate of Hp infection and incidence rate of active inflammation in antrum were obviously higher than that of gastric body and duodenal bulb.The detecting rate of Hp infection of duodenal bulb in 22 cases of duodenum ulcer was 54% which was significantly lower than that of antrum.Conclusion The Hp infection is a very important pathogenic factor of active inflammation in gastric mucosa on the basis of which the severe inflammation of mucosa and ulcer development.Therefore the early elimination of Hp is very important.
