BACKGROUND: Upper gastrointestinal endoscopically biopsied specimens are usually sent for the diagnosis of Helicobacter pylori infection. The study aimed to determine the relationship between the origin of positive Giemsa staining and the grade of gastritis based on the updated Sydney system.
METHODS: Gastric biopsy specimens taken at the lesser curvature and greater curvature sides of the corpus and greater curvature side of the antrum were stained with H&E, Giemsa, anti-East Asian-specific antibody and anti-H. pylori antibody stains. Pyrosequencing analysis was performed in cases that showed discrepancy between the Giemsa and anti-H. pylori antibody staining.
RESULTS: Seventy-two out of 150 cases (48%) stained positive for anti-H. pylori antibody, of which 68 (94.4%) stained positive for anti-East Asian-specific antibody stain. Twelve of the 20 cases with discrepant results for Giemsa and anti-H. pylori antibody stains exhibited Campylobacter hyointestinalis infection. The grades of neutrophil activity (p<0.001) and chronic inflammation (p<0.001) were lower for Campylobacter infection than for East Asian CagA H. pylori-related infection.
CONCLUSION: C. hyointestinalis is the most common cause of non-H. pylori-related Giemsa positive infection, and is associated with lower grades of neutrophil activity and chronic inflammation than East Asian CagA H. pylori-related infection.
