系统性红斑狼疮患者血清可溶性黏附分子的检测

Detection of soluble vascular cell adhesion molecule-1 and soluble intercellular adhesion molecule-1 in the sera of patients with systemic lupus erythematosus

目的检测系统性红斑狼疮(SLE)患者血清黏附分子中可溶性血管细胞黏附分子-1(sVCAM-1)、可溶性细胞间黏附分子-1(sICAM-1)的水平,并探讨其临床意义。方法采用酶联免疫吸附试验(ELISA)法,检测30名健康人和60例SLE患者血清sVCAM-1、sICAM-1水平,以分析其与SLE活动性变化关系。结果①SLE患者血清sVCAM-1平均水平为2342ng/ml,显著高于正常人对照组1240ng/ml(P<0.001)。②SLE患者中血清sICAM-1平均水平为802ng/ml,显著高于正常人对照组626ng/ml(P<0.001)。③SLE患者中,血清sVCAM-1水平活动期高于稳定期(P<0.05),sICAM-水平活动期高于稳定期(P<0.05)。④SLE组血清sVCAM-1和sICAM-1水平与SLE病情活动指数(SLEDAI)、抗dsDNA抗体水平及尿蛋白的发生呈正相关,与血清补体C3水平呈负相关。结论sVCAM-1,sICAM-1可能参与SLE发病机制。

Objective To detect the levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-l (sICAM-1) in the sera of patients with systemic lupus erythe-matosus (SLE) and their clinical significance was analysed. Methods Serum level of sVCAM-1 and sICAM-1 of 30 controls and 60 SLE patients were measured by enzyme linked immunosorbent assay (ELISA). Results 1 Serum levels of sVCAM-1 were significantly increasd in patients with SLE compared with those in normal controls (P<0.001); 2 Serum levels of sICAM-1 were significantly increasd in patients with SLE compared with those normal controls (P<0.001); 3 In SLE patients, serum levels of sVCAM-1 and sICAM-1 were significantly increasd in patients with active disease with those in patients with inactive disease (P<0.05); 4 Sermn levels of sVCAM and sICAM had negative correlation that serum C3 levels, and positive correlation with SLEDAI scores, serum levels of anti-dsDNA and urine protein. Conclusions The results suggest that sVCAM-1 and sICAM-1 may play certain role in the pathogenesis of SLE.
