摘要
目的:探讨慢性肝炎、肝硬化和原发性肝癌患者血清中自身抗体的变化规律。方法:收集342例慢性肝病和肝癌血清标本,以 Hep-2细胞和猴肝组织为抗原基质,采用间接免疫荧光法检测自身抗体。结果:慢性肝炎、肝硬化、肝癌患者抗核抗体(ANA)的阳性检出率分别为21.8%(35/160),27.5%(30/109)和34.2%(25/73),均明显高于对照组的3%(6/200)。3组ANA核型种类较多,但均以颗粒型为主。以蛋白质印迹法检测抗可提取性核抗原(ENA)抗体。发现40例ANA颗粒型的患者,有12例nRNP/Sm和(或)SSA阳性,3例Scl-70和2例Jo-1阳性;15例ANA均质型有7例为抗双链DNA抗体和1例抗组蛋白抗体。对照组中2例ANA颗粒型分别为nRNP/Sm和SSA阳性。3组病例的胞质抗体有多种,以抗线粒体抗体阳性率最高,肝硬化和肝癌组分别达12.8%和12.3%;慢性肝炎组为8.9%。结论:慢性肝炎、肝硬化、肝癌患者血清中不仅存在着自身抗体,而且显著高于正常人。ANA的靶抗原中除一部分是目前已鉴定的外,大部分有待于进一步鉴定。
Objective: To analyze autoantibodies in patients with chronic liver diseases and hepatocellular carcinoma (HCC). Methods: Immunofluoresence and Western blot were used to detect the autoantibodies on Hep-2 cells and monkeys liver tissue substrates. Results:The frequencies of ANA were significantly higher (P<0. 001 ) in patients with HCC (25/73 = 34. 2% ),cirrhosis (30/109 = 27. 5 % ) and chronic hepatitis (35/160 =21. 8 % ) than in normal control. Although a rage of fluorescence patterns was observed, the percentage of granular fluorescence was highest in the 3 groups. The result of ENA showed there were 12 cases nRNP/Sm and SS-A, 3 cases Scl-70, 2 cases Jo-1, 7 cases ds-DNA and 1 cases Histone. Several fluorescence patterns were observed in cytoplasmic, the frequency of anti-mitochondrial antibody was highest in all anti- cytoplasmic antibodies. Conclusion:These changes in ANA has a close relationship with transformation from chronic liver disease to HCC.
