Sa1738 Hepatocellular Growth Factor Increases Esophageal Epithelium Regeneration in an Experimental Ulcer Model in Rats

compared to that in H. pylori-negative patients (OR: 8.27, p<0.01) and the administration of a potent acid inhibitor effectively prevented peptic ulcer (OR: 0.12, 95%CI: 0.06-0.25,p<0.01) regardless of LDA usage.In LDA users with the SLCO1B1 TT genotype, the risk of peptic ulcer tended to be high (ulcer [+] vs. ulcer [-] = 87.5% vs. 68.8%,p=0.06).For those with the UGT1A6 and CYP2C9 * 2, however, the risk wasn't increased.The peptic ulcer risk of SLCO1B1 TT genotype was also significantly higher than that of C allele carriers (C/T and C/C genotypes) in LDA users (OR: 3.18, 95%CI: 1.04-9.74,p=0.04).In Addition, the risk of peptic ulcer in patients with the TT genotype without a potent acid inhibitor tended to be higher than risk in C allele carriers (OR: 5.08, 95% CI: 0.89-28.96,p=0.06).Conclusions: We demonstrated that the TT genotype of SLCO1B1 increased the risk of peptic ulcer induced by LDA usage.Prophylactic use of acid inhibitors might therefore be an effective personalized treatment for preventing of gastric mucosal injury.
