摘要 目的探讨类风湿性关节炎(RA)患者外周血白细胞VCS参数(V代表细胞体积,C代表射频传导性,S代表激光散射)变化与病情活动的相关性。方法用Beckman-Coulter LH750全自动分析仪检测190例处于不同活动期的RA患者及100例健康体检者的外周血,按照关节病情活动积分(DAS28)进行RA患者活动期和静止期分组,分析白细胞VCS参数的变化与RA患者病情活动度的关系。结果淋巴细胞(LY)和单核细胞(MO)参数V在RA活动期组、RA静止期组及健康对照组差异均有统计学意义(均P<0.05),RA活动期组的LY和MO参数V高于RA静止期,而RA静止期又高于健康对照人群(均P<0.05)。临床活动期患者的DAS28评分与LY、MO单数V存在正相关关系。LY、MO参数V的cut-off分别取84.61和167.43时,获得最大曲线下面积0.825(P=0.014)和0.775(P=0.038);对应灵敏度分别83.1%和78.6%,特异度分别53.3%和51.9%。结论外周血白细胞VCS参数可用来辅助诊断RA的临床活动期。
