摘要: 摘要 目的:探讨血清骨桥蛋白(OPN)水平与系统性红斑狼疮(SLE)脏器受累及疾病活动的关系。方法:63例SLE患者依据疾病活动指数(SLEDAI)分为缓解组(0~8分)31例和活动组(≥9分)32例;依据肾功能、尿液分析及肾脏病理检查结果分为肾损害组(32例)和无肾损害组(31例);依据肺间质有无纤维化将患者分为合并肺间质病变(ILD)组22例和未合并ILD组 41例;依据心电图、心脏彩色多普勒超声检查及心肌酶检查,分为心脏损害组25例和无心脏损害组38例;依据血常规检查结果分为合并血液系统损害组45例和无血液系统损害18例。采用酶联免疫吸附(ELISA)法检测上述SLE患者血清OPN水平,并与20例健康体检者(对照组)进行比较。结果:SLE患者血清OPN水平显著高于对照组(均P <0.05或P < 0.01)。SLE合并肾损害、肺间质病变、心脏损害、血液系统损害组的血清OPN水平明显高于无相应脏器受累患者(均P < 0.01),SLE患者的血清OPN水平与SLEDAI评分呈显著正相关(r=0.982,P<0.01)。结论: OPN在SLE发病机制中具有一定意义,并与疾病活动、脏器损害相关,血清OPN水平可以作为判断SLE疾病活动的实验室指标。

Abstract: Abstract Objective:To investigate the association between serum level of osteopontin (OPN), disease activity and organ damage of systemic lupus erythematosus (SLE). Methods:Six-three SLE patients and 20 healthy, age- and sex-matched controls were enrolled in this study. According to the systemic lupus erythematosus disease activity index (SLEDAI),patients were divided into renal damage group (0-8 score,n=32) and without renal damage group (≥9 score,n=31). According to the interstitial pulmonary fibrosis index, patients were divided into interstitial lung disease (ILD) group (n=22) and without ILD group (n=41). Patients were also divided into heart damage group (n=25) and without heart damage group (n=38) according to the electrocardiogram,echocardiogram and cardiac enzyme results. Based on hematological results, patients were divided into with cytopenia group (n=45) and without cytopenia group (n=18). The serum level of OPN was detected by enzyme-linked immunosorbent assay (ELISA) in patients of groups. Results:The serum level of OPN was significantly higher in SLE group than that of healthy controls (P<0.05 or P<0.01). The serum level of OPN was significantly higher in patients with renal damage, lung interstitial disease, heart damage and cytopenia than that of patients without organ involvement in SLE (P<0.01). The serum level of OPN was significantly positively correlated with SLEDAI in SLE patients (r=0.982,P<0.01). Conclusion:OPN plays a role in the pathogenesis of SLE and is related to the disease activity and organ damage. OPN may serve as an active disease laboratory marker of SLE.
