Logistic回归分析评价血清免疫球蛋白预测乙型肝炎相关肝硬化

目的 探讨血清免疫球蛋白G(IgG)、免疫球蛋白A(IgA)、免疫球蛋白M(IgM)对乙型肝炎相关肝硬化的诊断价值.方法 慢性乙型肝炎172例,其中病理诊断为肝硬化的患者28例,非肝硬化的患者144例.血清免疫球蛋白采用免疫透射比浊法测定.统计分析采用SPSS 12.0软件.肝硬化与非肝硬化患者之间血清IgG、IgA和IgM水平的比较采用两独市样本t检验;血清IgG、IgA和IgM水平诊断肝硬化的评价采用二分类Logistic回归分析.结果 肝硬化患荇血清IgG和IgA水平显著高于非肝硬化患者(t=4.702和3.034,P=0.000和0.003),血清IgM水平相近于非肝硬化患者(t=0.132,P=0.895).血清免疫球蛋白中,只有IgG符合Logistic回归分析纳入自变量标准(P<0.05).基于血清IgG建立的Logistic同归模型预测肝硬化的灵敏度、特异度、阻性预测值、阴性预测值、准确度分别为0.107、0.986,0.600、0.850、0.843.结论 血清IgG可作为预测乙型肝炎相关肝硬化的一项重要指标.

Appraisement of Serum Immunoglobulins for Prediction of Hepatitis B Associated Cirrhosis by Binary Logistic Regression Analysis

Objective To explore the diagnostic efficacy of serum immunoglobulins(IgG,IgA,IgM)for prediction of hepatitis B associated cirrhosis.Methods 172 consecutive patients were retrospectively studied,in which 28 patients and 144 patients were pathologically diagnosed as cirrhosis and non-cirrhosis.Serum immunoglobulins were determined by immunotrbidimetric assay.SPSS 12.0 software was used for statistical analyses.Independent samples test was used for comparisons of serum IgG,IgA,IgM levels between cirrhosis and...
