Histopathological severity of antral gastritis in relationship to Helicobacter pylori colonisation

The association between Helicobacter pylori (HP) colonisation in gastric antrum and the degree of severity and activity of gastritis and the concomitant relationship with gastric atrophy and intestinal metaplastic changes were studied. A total of 204 pieces of endoscopic biopsy tissues were collected from the outpatient endoscopy unit of New Yangon General Hospital in 1994. Routine Haematoxylin and Eosin stain as well as special stains such as modified Giemsa and Carbol fuchsin stains were used for bacterial identification and quantitative analysis. a significant correlation (P value <0.001) was obtained between density of HP colonisation and severity of gastritis as well as its activity (p value <0.001). However, no significant degree of atrophic changes and intestinal metaplastic changes were noted in these biopsies. a continuation for a better understanding of the pathogenesis of HP and its consequences is necessary.
