原发性胆汁性肝硬化检测自身免疫性肝病相关自身抗体谱的临床意义
【摘要】 目的:分析原发性胆汁性肝硬化(PBC)患者中自身免疫性肝病相关自身抗体谱的情况及其相关的临床价值。方法:选择2009年1月-2013年12月收治的PBC患者61例(PBC组)、自身免疫性肝炎(AIH)50例患者(AIH组)和其他肝病52例患者(对照组),检测各组的血清抗线粒体抗体(AMA)(采用间接免疫荧光法)、血清自身免疫性肝病相关自身抗体谱(采用ELISA法),包括AMA-M2、抗GP210抗体、抗SP100抗体、抗SLA抗体、抗LC1抗体、抗LKM-1抗体。结果:在PBC组中AMA、AMA-M2、抗GP210抗体、抗SP100抗体、抗LC1抗体、抗SLA抗体及抗LKM-1抗体阳性率分别为91.8%(56/61)、86.9%(53/61)、36.1%(22/61)、24.6%(15/61)、1.6%(1/61)、0(0/61)、1.6%(1/61);在AIH组中分别为18.0%(9/50)、6.0%(3/50)、8.0%(4/50)、14.0%(7/50)、0(0/50)、6.0%(3/50)、4.0%(2/50);而在对照组中分别为5.8%(3/52)、1.9%(1/52)、5.8%(3/52)、11.5%(6/52)、0(0/52)、0(0/52)、0(0/52)。AMA、AMA-M2和抗GP210抗体在PBC组中阳性率较AIH组明显增高(P0.01)。而抗SLA抗体在AIH组阳性率较PBC组明显增高(P0.01)。结论:抗LC1抗体、抗SLA抗体和抗LKM-1抗体在PBC和AIH患者中的阳性率低,检测该3种抗体的意义不大;因此筛查抗GP210抗体和AMA对PBC的诊断具有重要的临床意义。

【Abstract】 Objective:To explore the prevalence and study the clinic significance of autoimmune liver disease-related antibodies in patients with primary biliary cirrhoses(PBC).Method:The anti-AMA in 61 PBC(PBC group), 50 AIH(AIH group) and 52 other liver diseases(control group) were detected by IIF.Anti-AMA-M2,anti-GP210,anti-SP100,anti-SLA,anti-LC1 and anti-LKM-1 antibodies were measured by ELISA.Result:The positive rates of anti-AMA,anti-AMA-M2,anti-GP210,anti-SP100,anti-LC1,anti-SIA and anti-LKM-1 antibodies were 91.8%(56/61),86.9%(53/61),36.1%(22/61), 24.6%(15/61),1.6%(1/61),0(0/61)and 1.6%(1/61)in PBC group;18.0%(9/50),6.0%(3/50),8.0%(4/50),14.0%(7/50),0(0/50),6.0%(3/50)and 4.0%(2/50)in AIH group;5.8%(3/52),1.9%(1/52),5.8%(3/52),11.5%(6/52),0(0/52),0(0/52)and 0(0/52) respectively in control group.Anti-AMA,anti-AMA M2 and anti-GP210 were detected more frequently in PBC group than AIH group(P0.01),while anti-SLA was detected more frequently in AIH group than PBC group(P0.01).Conclusion:Anti-LC1, anti-SLA and anti-LKM-1 antibodies in PBC and AIH were detected at a very low frequency in the corhort.There was little significance for screening anti-LC1,anti-SLA,anti-LKM-1 anti
