1Effects of the myeloperoxidase 463 gene polymorphisms on development of atrophy in H pylori infected or noninfected gastroduodenal disease显示文摘AIM: To investigate the relationship between myelo- peroxidase polymorphisms as a host-related factor and atrophy caused by H pylori. METHODS: Our study enrolled 77 patients. Biopsy materials obtained during gastrointestinal endoscopies were evaluated for the presence of H pylori. Polymerase chain reaction-restriction fragment length polymorphism assay was used to characterize myeloperoxidase genotypes. RESULTS: Forty four patients (57.1%) were Hp (+) and 33 (42.9%) were Hp (-). Sixty six (85.7%) had GG genotype, 10 (12.9%) had GA genotype and 1 (1.29%) had AA genotype. The change in atrophy in relation to neutrophil infiltration was significant in Hp (+) patients (P = 0.0001). The change in atrophy in relation to neutrophil infiltration in patients with GG genotype was significant (P = 0.002). However, the change in atrophy in relation to neutrophil infiltration was not significiant in patients with Hp (+) GG genotype (r = 0.066, P = 0.63). CONCLUSION: Myeloperoxidase genotype is critical for development of atrophy in relation to the severity of inflammation. However, it is interesting to note that, H pylori does not show any additive effect on development of atrophy.mer Yilmaz Hakan Dursun Nesrin Gürsan ibrahim Pirim Arif Yilmaz Nihat Okcu 2007World Journal of Gastroenterology2007,13,8:6
