摘要
目的探讨自身免疫性肝病相关自身抗体在原发性胆汁性肝硬化(PBC)患者中的阳性状况及临床意义。方法采用间接免疫荧光法(IIF)检测61例PBC(PBC组)、50例自身免疫性肝炎(AIH组)和52例其他肝病(对照组)患者血清抗线粒体抗体(AMA),采用ELISA检测血清自身免疫性肝病相关自身抗体,包括AMA—M2,抗GP210抗体,抗SP100抗体,抗SLA抗体,抗LC1抗体和抗LKM-1抗体。结果AMA,AMA—M2,抗GP210抗体、抗SP100抗体、抗LC1抗体、抗SLA抗体和抗LKM-1抗体在PBC组的阳性率分别为91.8%(56/61),86.9%(53/61),36.1%(22/61),24.6%(15/61),1.6%(1/61),0%(O/61)和1.6%(1/61);在AIH组的阳性率分别为18.0%(9/50),6.0%(3/50),8.0%(4/50),14.0%(7/50),0%(o/50),6.0%(3/50)和4.0%(2/50);在对照组的阳性率分别为5.8%(3/52),1.9%(1/52),5.8%(3/52),11.5%(6/52),0%(0/52),0%(0/52)和0%(0/52)。AMA,AMA-M2和抗GP210抗体在P1312组的阳性率显著高于AIH组(,值分别为101.1,100.8和11.2,P值均〈O.01)。而抗SLA抗体在A1H组的阳性率高于PBC组(x2=9.5,P〈0.01)。结论抗LCl抗体、抗SLA抗体和抗LKM—1抗体在PBC和AIH中阳性率较低,筛查这3种抗体的临床意义可能不大。临床筛查抗GP210抗体和AMA对PBC诊断有重要意义。
Objective To explore the prevalence and study the clinic significance of autoimmune liver disease-related antibod- ies in patients with primary biliary cirrhoses (PBC). Methods 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. Results The positive rates of anti-AMA,anti-AMA-M2,anti- GP210 ,anti-SP100,anti-LC1, anti-SLA 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 :[requently in PBC group than AIH group( f = 101.1,100. 8 and 11.2, P〈0. 01), while anti-SLA was detected more frequently in AIH group than PBC group ( x2 = 9.5, P〈0.01). Conclusion Anti-LC1, anti-SLA and anti- LKM-I 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-I antibodies in patients with antoimmune liver diseases. It is of importance to detect anti-AMA and anti-GP210 antibodies for diagnosis of PBC.
