摘要

Aim: Whether genetic polymorphisms of osteopontin (OPN) coding gene, SPP1, determine the risk of gastric precancerous intestinal metaplasia (IM) in Helicobacter pylori infected patients. Patients & methods: Helicobacter pylori infected patients (100 with and 210 without IM) were recruited to evaluate the associations of SPP1 promoter polymorphisms with gastric IM and adjusted for age, sex and smoking. Gastric OPN expression and inflammation were evaluated by immunohistochemistry, and haemotoxylin and eosin stain. Results: Only in males, but not females, carriage of both GG genotype at rs11730059 and C-G-C haplotype at rs6833161-rs2853744-rs11730582 significantly increased the IM risk (OR: 4.92; 95% CI: 1.65-14.65; p = 0.004). Nearly 87.5% of males with IM carried risky genotype or haplotype. Carriers of the risky genotype or haplotype also had increased gastric OPN expression (p = 0.038) and inflammation (p = 0.007). Conclusion: SPP1 polymorphisms predispose to IM development in H. pylori infected males.
