Pro- and anti-inflammatory cytokines, including interleukin 10 (IL-10), play an essential role in atherogenesis. Increased IL-10 production has been found among carriers of the IL10 [TCATA] haplotype, which is formed by five polymorphisms at position -3575, -2763, -1082, -819, and -592 in the promoter region of the IL10 gene. Due to linkage disequilibrium, the presence of the [TCATA] haplotype can be unequivocally determined by analysis of the IL10-592C>A polymorphism. The purpose of the present study was to investigate a hypothesized association between the haplotype-tagging IL10 -592C>A polymorphism and the presence of retinal artery occlusion (RAO).
The present case-control study was comprised of 194 patients with RAO and 257 normal control subjects. Genotypes of the IL10 -592C>A polymorphism were determined by fluorogenic exonuclease (TaqMan) assay.
Carriers of the IL10 -592A-allele, indicating the presence of the IL10 [TCATA] haplotype, were found significantly more often in controls than among patients with RAO (48.6% versus 36.1%; p=0.008). In a logistic regression analysis after adjusting for age, sex, arterial hypertension, diabetes mellitus, hypercholesterolemia, and smoking habits, carriage of the IL10 -592A-allele was associated with an odds ratio of 0.65 (95% CI: 0.44-0.97) for RAO.
Our data suggest that the IL10 [TCATA] haplotype, identified by the presence of the IL10 -592A-allele, may exert a protective effect against RAO.
促炎和抗炎细胞因子,包括白细胞介素10(IL-10),在动脉粥样硬化形成中起重要作用。在IL10 [TCATA]单倍型携带者中发现IL-10产生增加,该单倍型由IL10基因启动子区域-3575、-2763、-1082、-819和-592位置的五个多态性形成。由于连锁不平衡,[TCATA]单倍型的存在可通过分析IL10 -592C>A多态性明确确定。本研究的目的是调查单倍型标签IL10 -592C>A多态性与视网膜动脉阻塞(RAO)存在之间的假设关联。
本病例对照研究包括194例RAO患者和257例正常对照受试者。通过荧光外切酶(TaqMan)测定法确定IL10 -592C>A多态性的基因型。
在对照组中发现携带IL10 -592A等位基因(表明存在IL10 [TCATA]单倍型)的情况明显多于RAO患者(48.6%对36.1%;p=0.008)。在对年龄、性别、动脉高血压、糖尿病、高胆固醇血症和吸烟习惯进行调整后的逻辑回归分析中,携带IL10 -592A等位基因与RAO的比值比为0.65(95%可信区间:0.44 - 0.97)相关。
我们的数据表明,由IL10 -592A等位基因的存在所确定的IL10 [TCATA]单倍型可能对RAO具有保护作用。
