摘要 目的:探讨转化生长因子(TGF-β)和白介素-18(IL-18)在狼疮肾炎(LN)患者血清中的表达及临床意义。方法:使用ELISA法对46LN患者血清进行检测,并与31例正常人作对照。结果:LN患者血清中IL-18的水平显著高于正常对照组(P<0.01)。LN患者血清中的TGF-β水平显著低于正常对照组(P<0.01)。血清IL-18的表达和LN患者SLEDAI评分之间有相关性(P<0.01)。抗dsDNA、抗Sm、抗nRNP、aCL IgG抗体在LN组有较高的阳性率,与对照组比较差异有显著性(P<0.05)。将IL-18、TGF-β、抗dsDNA抗体、抗Sm抗体、抗nRNP抗体和aCLIgG抗体分别引入LOGISTIC回归进行统计分析。结果:入选的自变量包括血清IL-18、抗dsDNA抗体、血清TGF-β、抗Sm抗体(P<0.05)。结论:在LN患者中,可能存在着血清IL-18的高表达和血清TGF-的低表达。血清IL-18可能是反映了系统性红斑狼疮患者并发肾脏损害的一个重要的指标。抗dsDNA抗体、抗Sm抗体、血清IL-18、血清TGF-β可能参与了LN的发病进程。
