World J Gastroenterology: 血清铜蓝蛋白可预测乙肝病毒感染患者的肝纤维化程度

全球约有2.92亿人感染过或正感染着乙型肝炎病毒(HBV);但是,只有不到5%的感染者接受了抗病毒治疗。慢性HBV感染可引起纤维化,最终可发展为肝癌。

        全球约有2.92亿人感染过或正感染着乙型肝炎病毒(HBV);但是,只有不到5%的感染者接受了抗病毒治疗。慢性HBV感染可引起纤维化,最终可发展为肝细胞癌,血清丙氨酸氨基转移酶(ALT)水平的评估是一种相对便宜的生化测试,广泛用于检测肝损伤。然而,最近的证据表明,一些患者ALT正常也可以发生严重的肝纤维化。肝活检(LB)是诊断肝纤维化的金标准。然而,它有术后并发症的风险,而血清铜蓝蛋白(CP)是一种由肝细胞分泌的糖蛋白,在健康人体内携带着超过95%的循环铜。有研究表明,CP具有很强的抗氧化功能和禁止显示脂质过氧化。以前的数据显示,CP与肝纤维化呈负相关关系,提示CP是诊断肝纤维化的有用的标志。

 

        研究人员回顾性评估了275名HBV感染者。对CP和纤维化阶段之间的关联进行统计分析。构建了包括CP [铜蓝蛋白乙型肝炎病毒(CPHBV)]的预测指标来预测明显的纤维化,并与先前报道的模型进行了比较。

 

        结果显示:血清CP与肝纤维化呈负相关(r = -0.600)。使用CP,预测严重纤维化,晚期纤维化和肝硬化的曲线下面积(AUC)分别为0.774、0.812和0.853。使用CP,血小板(PLT)和HBsAg水平开发CPHBV模型,以预测明显的纤维化。该模型预测严重纤维化,晚期纤维化和肝硬化的AUC分别为0.842、0.920和0.904。CPHBV在预测HBV感染的显着纤维化方面优于天冬氨酸转氨酶(AST)与PLT比率指数。

 

 

        因此,研究人员说道由CP构建的CPHBV评分可以准确预测HBV感染的患者个体的肝纤维化程度。
