摘 要:目的分析人类白细胞抗原B27(HLA-B27)在脊柱关节炎(SpA)中的诊断价值。方法采用流式细胞术检测298例SpA患者(SpA组)和195例非SpA患者(非SpA组)HLA-B27的表达水平。结果 493例患者中,HLA-B27阳性227例。SpA组中强直性脊柱炎(AS)、幼年脊柱关节炎(JSpA)、反应性关节炎(ReA)、未分化型脊柱关节炎(USpA)和银屑病关节炎(PsA)患者的HLA-B27阳性率,分别为87.66%、59.09%、58.33%、37.18%、25.00%;非SpA组中类风湿关节炎、风湿性关节炎、颈椎或腰椎疾病、骨关节炎、痛风性关节炎患者的HLA-B27阳性率,分别为18.18%、17.86%、16.67%、11.76%、0.00%。SpA组与非SpA组HLA-B27阳性率比较差异有统计学意义(P<0.01)。结论 HLA-B27与SpA密切相关,可为临床诊断SpA,尤其是AS提供参考。Objective To analyze human leucocyte antigen B27(HLA-B27) diagnostic value in spondyloarthritis(SpA) .Methods Using flow cytometry to detect HLA-B27 expressions of 298 SpA patients(SpA group) and 195 non-SpA patients(non-SpA group) .Results 227 patients were positive in the 493 patients .In SpA group ,the positive rates of HLA-B27 expressing in ankylo-sing spondylitis (AS ) ,juvenile spondyloarthritis (JSpA ) ,reactive arthritis (ReA ) ,undifferentiated spondyloarthritis (USpA ) , psoriatic arthritis(PsA) were 87 .66% ,59 .09% ,58 .33% ,37 .18% ,25 .00% ,respectively .In non-SpA group ,the positive rates of HLA-B27 expressing in rheumatoid arthritis ,rheumatic arthritis ,cervical or lumbar disease ,osteoarthritis ,gouty arthritis were 18 . 18% ,17 .86% ,16 .67% ,11 .76% ,0 .00% ,respectively .The SpA group and the non-SpA group of HLA-B27 positive comparative differences was statistically significant(P〈0 .01) .Conclusion The HLA-B27 is correlated with SpA ,and can provide reference for clinical diagnosis of SpA especially the AS .
