系统性红斑狼疮患者血清几种趋化因子的检测

Serum Levels of Chemokines in the Patients With Systemic Lupus Erythematosus

目的探讨血清趋化因子单核细胞趋化及活化因子/单核细胞趋化蛋白-1(MCAF/MCP-1)、正常T细胞表达和分泌的活化调节蛋白(RANTES)水平与系统性红斑狼疮疾病活动程度的关系及意义。方法采用双抗体夹心ELISA法检测血清MCAF、RANTES水平。结果①SLE患者血清MCAF水平明显高于正常人;②活动期患者血清MCAF水平明显高于非活动期;③肾损组与非肾损组相比,血清MCAF、RANTES水平差异均无显著性。结论趋化因子MCAF可能参与系统性红斑狼疮的发病机制,且血清MCAF水平可作为反映疾病活动性的一个指标。

Objective To determine the relationship between serum levels of MCAF/MCP-1 (monocyte chemotactic and activating factor/monocyte chemoattractant protein-1), RANTES(regulated on activation, normal T-cell expressed and secreted) and the disease activity of systemic lupus erythematosus(SLE). Methods Serum levels of MCAF and RANTES were measured by ELISA. Results ①Serum level of MCAF but not RANTES, was significantly increased in patients with SLE as compared with controls. ②Serum level of MCAF but not RANTES, was markedly higher in patients with active disease than those with inactive disease. ③No significant differences were found in the serum levels of MCAF and RANTES between patients with renal damage and those without. Conclusions These results suggest that MCAF may be involved in the pathogenesis of SLE, and serum MCAF levels could be an indicator for the disease activity of SLE.
