摘要 目的探讨抗髓过氧化物酶(anti-myeloperoxidase,MPO)抗体检测对诊断自身免疫性肝炎(autoimmune hepati-tis,AIH)的临床意义及诊断的评估方法。方法研究对象为56例AIH患者、176例非AIH及40例健康体检者,采用ELISA法检测抗MPO抗体和间接免疫荧光法(IIF)检测抗核抗体(anti-nuclear antibodies,ANA)、抗平滑肌抗体(smoothmuscle antibod-ies,SMA)和抗中性粒细胞胞质抗体(anti-neutrophil cytoplasmic antibodies,ANCA)等自身抗体并观察其临床评估指标,对其结果进行回顾性分析。结果1)56例AIH与176例非AIH检测MPO结果显示其阳性率分别为64.3%(36/56)和1.7%(3/176);组间比较,P<0.01差异有非常显著性意义。2)AIH及非AIH各疾病检测结果为SMA抗体阳性率最高为69.6%(39/56),MPO、ANCA和SMA抗体检测在AIH与PBC中,经χ2检验,P<0.01差异均有非常显著性意义。3)AIH患者的临床评价指标在患病率不改变的情况下,结果显示除阴性似然比外最高均为SMA;阴性似然比ANCA最高为1.25。4)AIH-I患者检测MPO抗体的结果阳性率为87.2%(34/39);AIH-Ⅱ患者无1例阳性;AIH-Ⅲ患者2例阳性。表明AIH-I患者与其密切相关。5)AIH-I患者的临床评价指标在患病率不改变的情况下,结果显示除阴性似然比外亦是SMA最高;阴性似然比ANCA最高为0.19。结论血清抗髓过氧化物酶抗体联合其他自身抗体的检测对诊断、治疗和阻止AIH的发展有着十分重要作用。对提高AIH在临床上同其它肝病鉴别诊断和治疗有着非常重要的意义。 Objective To explore the clinical value of anti-myeloperoxidase (MPO) antibody detection in the diagnosis of autoimmune hepatitis (AIH). Methods In 56 cases of AIH,176 patients of non-AIH,and 40 healthy persons,enzyme-linked immunosorbent assay (ELISA) was used to detect MPO,and indirect immunofluorescence (IIF) was used to detect anti-nuclear antibodies (ANA),smooth muscle antibodies (SMA),and anti-neutrophil cytoplasmic antibodies (ANCA). The result was retrospectively analyzed. Results The positive rate ...
