BACKGROUND/AIMS: Single nucleotide polymorphisms (SNPs) are associated with aspirin-induced peptic ulcers. However, SNPs of specific genes vary among races, and data regarding SNPs in the Korean population are scarce. In this study, we aimed to investigate the relationships between SNPs of the COX-1, IL-1β, IL-1RN, and TNF genes and aspirin-induced peptic ulcers, as pilot research in a Korean population.
METHODS: Patients who had been taking low-dose aspirin (100 mg) for at least 4 weeks were prospectively enrolled. DNA was extracted from whole blood, and DNA sequencing was subsequently performed.
RESULTS: A total of 48 patients were enrolled (23 peptic ulcer patients vs 25 nonulcer controls). Three exon SNPs (IL-1β -581C/T [rs1143627], IL-1β -1061C/ T [rs16944], and IL-1RN -1129 [rs4251961]) and one intron SNP (IL-1β IVS2+242C/T) were significantly different between the two groups. On the multivariate analysis after adjustments for age and sex, the CC/CT genotypes of IL-1β -581C/ T, and the CT/TT genotypes of IL-1β -1061C/T were positively associated with aspirin-induced peptic ulcers (odds ratio [OR], 4.6, 95% confidence interval [CI], 1.054 to 20.303, p=0.04; OR, 4.6, 95% CI, 1.054 to 20.303, p=0.04).
CONCLUSIONS: The IL-1β -581C/T and IL-1β -1061C/T genotypes may be associated with low-dose aspirin-induced peptic ulcers in a Korean ethnic group.
