主  题:Duodenal ulcer Helicobacter pylorr Myeloperoxidase Polymorphism 

摘      要:AIM: To elucidate the relations between the myeloperoxidase ^(-468)G→a polymorphism and the development of duodenal ulcer (DU), and to investigate the impacts of this host genetic polymorphism on the histopathological features of Helicobacter pylori (H py/ori)-related gastritis. METHODS: In a case-control study of 115 consecutive DU patients and 182 controls, the myeloperoxidase ^(-468)G→A polymorphism was genotyped. Additionally, gastric mucosal changes were examined according to the updated Sydney System. RESULTS: The two study groups differed in the distributions of myeloperoxidase genotypes (P=0.008). All six individuals carrying myeloperoxidase A/A genotypes were in the DU group. The carriage of myeloperoxidase allele A and H pylori infection were associated with an increased risk of DU with odds ratios (OR) of 2.3 and 5.8, respectively. The combined risk of the carriage of myeloperoxidase allele A and H pylori infection for DU was 8.7 (95% CI, 3.5-21.8). In the H pylori-infected individuals, allele A carriers displayed higher bacterial density scores (P=0.04) in the antrum than did non-carriers. CONCLUSION: This work verifies for the first time the association of myeloperoxidase ^(-468)G→A polymorphism with antral H pylori density and DU disease. The mechanisms underlying this genetic polymorphism in developing DU disease merit further investigations.
