AIM: To investigate the roles of nuclear factor kappa B (NF-κB), humanb-defensin-2 (HBD-2) and antral gastritis in H pylori-positive peptic ulcer (PU).
METHODS: Patients with H pylori-positive (n = 40) or H pylori-negative (n = 17) PU were included in this study. Eight individual were selected as normal controls. Antral histopathology was observed in the patients and controls. The expression of NF-κBp65 andb-denfensin-2 were measured by immunohistochemistry, and then compared between H pylori-positive and negative patients and normal group as well as between patients with different stages of PU by One-Way ANOVA. Nonparametric statistics was used to analyze the correlations of H pylori infection, NF-κBp65, HBD-2 expression with the degree of antral gastritis. Meanwhile, the relationship between expression of NF-κBp65 and HBD-2 was also analyzed in H pylori-positive PU.
RESULTS: The histological severities of both active and chronic inflammation were correlated with H pylori density (active: r = 0.374, P < 0.01; chronic: r = 0.333, P < 0.05). NF-κBp65 was expressed mainly in the nucleus of gastric epithelial and mesenchymal cells in lamina propria while HBD-2 was expressed mainly in the cytoplasm of the surface cells of gastric mucosal epithelium. The expression of NF-κBp65 and HBD-2 were significantly higher in H pylori-positive patients than those in H pylori-negative ones (6.4 ± 3.28 vs 3.78 ± 2.16, P < 0.01; 12.96 ± 5.03 vs 4.69 ± 2.05, P < 0.01), and both expression of NF-κBp65 and HBD-2 were correlated with histological severity of active and chronic inflammation (active: r = 0 ......
