Multiple sclerosis (MS) is associated with human leukocyte antigen (HLA) HLA-DRB115. Recent evidence that CD8 T cells are implicated in MS suggests that HLA class I may also contribute. An association of HLA-A02 and A*03 alleles has been described.
We examined the influence of HLA-A02 and HLA-A03 in Portuguese patients with MS, independently of HLA-DRB1*15 using a logistic regression model.
DRB115 increased the risk of developing MS and HLA-A02 decreased the risk. A03 had no effect. To analyze if HLA-A02 association was independent from DRB1*15, an interaction between these two alleles was introduced in the model; no significant interaction was found.
多发性硬化症（MS）与人类白细胞抗原（HLA）-DRB115相关。最近有证据表明CD8 T细胞与MS有关，这表明HLA I类分子可能也有作用。已有关于HLA-A02和A*03等位基因关联的描述。
我们使用逻辑回归模型，在不考虑HLA-DRB115的情况下，研究HLA-A02和HLA-A*03对葡萄牙MS患者的影响。
DRB115增加了患MS的风险，而HLA-A02降低了风险。A03没有影响。为分析HLA-A02的关联是否独立于DRB1*15，在模型中引入了这两个等位基因之间的相互作用；未发现显著的相互作用。
