系统性红斑狼疮患者循环annexin Ⅱ水平的变化及临床意义

目的 探讨系统性红斑狼疮(SLE)患者血自细胞annexinⅡ的表达水平及其在SLE中的临床意义.方法 采用流式细胞术检测SLE患者35例,慢性肾炎患者10例,糖尿病肾病(DN)患者10例,健康对照组20名血白细胞annexinⅡ的表达水平,并分析其与临床指标间的相关性.采用t检验、方差分析及直线相关性分析进行统计学分析.结果 SLE、DN组患者血白细胞annexin Ⅱ水平(7.1±2.9)%,(8.0+3.7)%]均显著低于健康对照组(10.6±1.6)%](P<0.01,P<0.05);有活动性(SLE疾病活动指数(SLEDAI)评分≥9分]的SLE患者annexinⅡ水平(5.6±2.4)%]显著低于非活动性(SLEDAI评分<9分)的SLE患者(7.8±2.8)%](P<0.05);SLE患者annexinⅡ水平与尿蛋白/肌酐呈负相关(r=-0.382,P<0.05),与血白蛋白呈正相关(r=0.439,P<0.01),与SLEDAI呈负相关(r=-0.417,P<0.05),与D-二聚体呈负相关(r=-0.336,P<0.05).结论 SLE患者血白细胞annexin Ⅱ表达水平降低,参与了SLE患者高凝和继发性纤溶亢进状态的发生发展的病理生理过程,可作为一种早期反映SLE血栓前状态的良好指标,对判断SLE的活动性及疗效有一定的帮助.

Abstract：

Objective To compare the level of Annexin Ⅱ in patients with systemic lupus erythematosus(SLE),diabetic nephropathy(DN),chronic glomerulonephritis and normal controls,and explorle the significance of the annexin Ⅱ in SLE.Methods Thirty-five cases of patients with SLE,ten cases of patients with DN,ten cases of patients with chronic glomerulonephritis were enrolled in this study,twenty cases of healthy controls were also enrolled.Circulating annexin Ⅱ in white blood cells was detected bv flow cytometry.Student's t test,variance analysis and Lineat correlation analysis were used for statistial analysis.Resuits Compared with healthy controls,the level of annexin Ⅱ in white blood cells in SLE patients (7.1±2.9)%and DN patients(8.0±3.7)%were significantly lower than that of the healthy controls(P<0.01,p<0.05).In the SLE group,the level of annexin Ⅱ of patients who had more active disease(SLEDAI≥9)decreased more thall those with less active disease(SLEDAI<9),(P<0.05).A positive correlation was found between annexin Ⅱ and serum albumin level(r:0.439,P<0.01),but negative correlation was found between annexin and urine protein/urine creatinine(r=-0.382,P<0.05),SLEDAI(r=-0.417,P<0.05),D-dimer(r=-0.336.p＜0.05) levels.Conclusion The level of annexin Ⅱ is decreased in patients with SLE,so it can renectthe abnormality of coagulation and fibrinolytic systems,and it may be used as a good indicator for prothrombotic status in SLE patients.It can be helpful to evaluatethe activity of the disease and the therapeutic efficacy.
