To investigate the association of interleukin 8 (IL-8) gene polymorphisms with the risks of inflammatory bowel disease (IBD).
Single nucleotide polymorphisms (SNPs) of IL-8 gene at -845 T/C, -738 T/A, -353 A/T, -251 T/A and +678 T/C were analyzed in 183 IBD patients. They included Crohn's disease (CD, n = 41), ulcerative colitis (UC, n = 142) and healthy controls (n = 160). The methods of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-sequence specific primers (PCR-SSP) were employed.
No association was observed between any of these five SNPs in IL-8 gene with the occurrence of IBD. A specific haplotype AAT (-353 A/T, -251 T/A & +678 T/C) was over-represented in UC cases when compared with controls (31.0% vs 23.7%, P = 0.046). But the distributions of this haplotype did not show significant difference between CD cases and controls.
Our data support a significant but modest association between the AAT haplotype of IL-8 gene and UC (OR = 1.441, 95%CI 1.007 - 2.063).
探讨白细胞介素8(IL-8)基因多态性与炎症性肠病(IBD)发病风险的相关性。
对183例IBD患者进行IL-8基因-845 T/C、-738 T/A、-353 A/T、-251 T/A和+678 T/C位点的单核苷酸多态性(SNP)分析。患者包括克罗恩病(CD,n = 41)、溃疡性结肠炎(UC,n = 142)及健康对照者(n = 160)。采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)及聚合酶链反应-序列特异性引物(PCR-SSP)方法。
未观察到IL-8基因这5个SNP中的任何一个与IBD发病存在关联。与对照组相比,UC患者中一种特定单倍型AAT(-353 A/T、-251 T/A及+678 T/C)的出现频率过高(31.0%对23.7%,P = 0.046)。但该单倍型在CD患者与对照组之间的分布未显示出显著差异。
我们的数据支持IL-8基因的AAT单倍型与UC之间存在显著但适度的关联(OR = 1.441,95%CI 1.007 - 2.063)。
