摘  要:目的:探讨自身抗体测定对诊断自身免疫性肝炎的临床意义.方法:采用间接免疫荧光法(IIF)检测47例自身免疫性肝炎患者、158例非自身免疫性肝炎患者及40例健康体检者体内抗核抗体(ANA)、抗平滑肌抗体(SMA)、抗中性粒细胞胞质抗体(ANCA)、抗线粒体抗体(AMA)等自身抗体,ELISA法检测抗MPO抗体,并对结果进行回顾性分析.结果:ANA、SMA及ANCA检出率的比较,结果显示AIH中阳性率最高为SMA(66.0%, 31/47),而非AIH中则为6.3%(10/158),两组差异有非常显著性意义(P<0.01).经X2检验, SMA、AMA和MPO抗体检测在AIH与PBC中,均有非常显著性意义(P<0.01).AIH各型自身抗体检测结果表明,AIH-Ⅰ与ANA、SMA和ANCA相关,AIH-Ⅱ与LKM相关,而AIH=Ⅲ与SLA和ANCA相关.结论:血清自身抗体的检测对诊断、治疗和阻止自身免疫性肝炎的发展有着十分重要作用,对提高AIH在临床上同其他肝病鉴别诊断和治疗有着非常重要的意义.AIM: To evaluate the clinical significance of autoantibody detection in the diagnosis of autoimmune hepatitis (AIH). METHODS: Indirect immunofluorescence was used to detect the expression of anti-nuclear antibody (ANA), anti-smooth muscle antibody (SMA), antineutropil cytoplasmic antibody (ANCA), and anti-mitochondrial antibody (AMA) in patients with autoimmune hepatitis (AIH, n = 47), non-autoimmune hepatitis (n = 158) and healthy controls (n = 40). Enzyme linked immunosorbent assay (ELISA) was used to examine the content of anti-myeloperoxidase (MPO) antibody. The result was retrospectively analyzed. RESULTS: Comparison between the rates of ANA, SMA and ANCA showed that SMA was found the highest in AIH patients (66.0%, 31/47), significantly higher than that in non-AIH patients (6.3%, 10/158). After chi-square test, SMA and AMA and MPO were markedly different between AIH and primary biliary cirrhosis (PBC) patients (P 〈 0.01). Finally, ANA, SMA and ANCA were correlated with AIH- Ⅰ, anti- liver/kidney microsomal antibody (LKM) with AIH-Ⅱ, and anti-soluble liver antigen antibody (SLA), ANCA with AIH-Ⅲ. CONCLUSION: Detection of autoantibodies is helpful in the diagnosis and therapy of AIH.
