HLA-DR和 HLA-DQ等位基因与口腔扁平苔藓的相关性

目的研究上海及江浙地区汉族人群人类白细胞抗原(HLA)-DRB1、HLA-DQB1等位基因与口腔扁平苔藓(OLP)发病的关系。方法采用聚合酶链式反应-序列特异性引物(PCR-SSP)法,检测上海及江浙地区44例OLP患者和150例正常对照者的HLA-DRB1、HLA-DQB1等位基因表现频率,所得数据在OLP与正常对照之间以及不同类型OLP患者之间进行比较分析。结果与正常对照组相比,OLP组HLA-DRB1*09和HLA-DRB1*07基因表现频率均明显增高,分别为56.8%vs31.3%(P<0.01)和27.3%vs13.3%(P<0.05);而HLA-DQB1*06基因表现频率则显著降低(18.8%vs42.5%)(P<0.01)。OLP组内比较显示,HLA-DRB1*04表达频率在具有糜烂表现的OLP患者中显著升高,与白纹组相比具有显著性差异(P<0.05)。结论HLA-DRB1*09、DRB1*07等位基因与上海及江浙地区部分人群的OLP易感性相关;HLA-DQB1*06等位基因可能与OLP的抵抗性相关联;HLA-DRB1*04可能与糜烂型OLP的发生有关。

Association of HLA-DR/DQ with Oral Lichen Planus

Objective To investigate the association of human leukocytes antigen(HLA)-DR/DQ with oral lichen planus(OLP) in the area of Yangtze River Delta. Methods HLA-DRB1 and DQB1 genotyping of 44 unrelated OLP patients and 150 normal controls were performed by polymerase chain reaction-sequence specific primers(PCR-SSP) method.The data were compared between the OLP group and normal controls,and between different types of OLP patients. Results The frequency of HLA-DRB1*09 and HLA-DRB1*07 alleles were significantly higher in OLP group than those in normal controls(56.8% vs 31.3% and 27.3% vs 13.3%,P<0.01 and P<(0.05).) However,the frequency of HLA-DQB1*06 was significantly decreased in OLP group than that in normal controls((18.8%) vs 42.5%,P<0.01).HLA-DRB1*04 allele was more frequent in OLP patients with erosive manifestation than those with reticular manifestatio1n(P<0.05). Conclusion HLA-DRB1*09 and DRB1*07 are associated with the development of OLP in the area of Yangtze River Delta.HLA-DQB1*06 may be associated with the resistance to OLP,and HLA-DRB1*04 with the erosive manifestation of OLP.
