Systemic lupus erythematosus (SLE) is a complicated autoimmune disease. Although its pathogenesis is not clear, cytokine may be involved in it. So we investigated serum levels of macrophage-derived chemokine (MDC), and matrix metalloproteinase-9 (MMP-9), and to determine the relationship between serum levels and the disease activity of SLE.
Serum levels of MDC and MMP-9 were measured by enzyme-linked immuno sorbent assay (ELISA).
Significantly decreased serum levels of MDC and MMP-9 were found in SLE as compared to those in controls (P<0.001 P<0.001), but serum levels of MDC and MMP-9 increased after treatment (P<0.001 P<0.05). Serum levels of MDC and MMP-9 were lower in patients with active disease than those with inactive disease (P<0.001 P<0.05). Significantly decreased serum levels of MDC and MMP-9 were found in patients with renal damage than those without the damage (P<0.001 P<0.05). Serum level of MDC was lower in patients with arthritis than those without the damage (P<0.001), but serum level of MMP-9 has no significant difference in two groups (P>0.05).
The present data suggest that MDC and MMP-9 may be involved in the pathogenesis of SLE, and serum levels of MDC and MMP-9 could be markers of monitoring disease activity, renal damage, disease progression and improvement in SLE.
系统性红斑狼疮（SLE）是一种复杂的自身免疫性疾病。尽管其发病机制尚不清楚，但细胞因子可能参与其中。因此，我们研究了巨噬细胞衍生趋化因子（MDC）和基质金属蛋白酶-9（MMP-9）的血清水平，并确定血清水平与SLE疾病活动度之间的关系。
采用酶联免疫吸附测定（ELISA）法检测血清MDC和MMP-9水平。
与对照组相比，SLE患者血清MDC和MMP-9水平显著降低（P<0.001，P<0.001），但治疗后血清MDC和MMP-9水平升高（P<0.001，P<0.05）。活动期疾病患者的血清MDC和MMP-9水平低于非活动期患者（P<0.001，P<0.05）。有肾脏损害的患者血清MDC和MMP-9水平显著低于无肾脏损害的患者（P<0.001，P<0.05）。有关节炎的患者血清MDC水平低于无关节损害的患者（P<0.001），但两组患者血清MMP-9水平无显著差异（P>0.05）。
目前的数据表明，MDC和MMP-9可能参与SLE的发病机制，血清MDC和MMP-9水平可能是监测SLE疾病活动度、肾脏损害、疾病进展及病情改善的指标。
