人类白细胞抗原-B27与强直性脊柱炎的相关性分析

The correlation analysis of HLA-B27 in the diagnosis of ankylosing spondyfitis

目的 探讨人类白细胞抗原-B27(HLA-B27)检测在强直性脊柱炎(AS)早期诊断中的临床价值.方法 使用序列特异性引物-聚合酶链式反应(PCR-SSP)法对500例健康体检者(非AS对照组)、360例AS疑似患者(AS疑似组)和100例AS患者(AS组) 进行HLA-B27抗原检测.结果 非AS对照组、AS疑似组和AS组的HLA-B27阳性率分别为3.3%、 48.9%和92.5%,AS组、AS疑似组的HLA-B27阳性率明显高于非AS对照组(P<0.01),AS组的HLA-B27阳性率明显高于AS疑似组(P<0.01).结论 HLA-B27抗原与AS疾病相关,检测HLA-B27抗原对疑似AS患者的早期诊断有重要意义.

Objective To explore the clinical value of HLA-B27 in patients with ankylosing spondyfitis. Methods Using PCR-SSP to detect the HLA-B27 of 500 healthy people (non-AS group),360 presumed AS patients (suspectable group) and 100 AS patients(AS group). Results The positive rates of HLA-B27 of non-AS group, suspectable group, AS group were 3.3%,48.9% and 92.5%, respectively. The positive rate of HLA-B27 of AS group and suspectable group was obviously higher than that in non-AS group (P＜0.05). The positive rate of HLA-B27 of AS group was obviously higher than that in suspectable group (P＜0.05). Conclusions There is positive correlation between AS and HLA-B27.It is very important for the early diagnosis of AS.
