摘要 目的探讨血浆氨基酸浓度诊断慢性乙型肝炎肝组织病理状态的效能。方法 148例经肝组织病理学检查的慢性乙型肝炎患者入选本研究。血浆氨基酸浓度测定采用Agilent 1100系列高效液相色谱仪,氨基酸标准品及衍生试剂购自Agilent公司。血浆氨基酸浓度诊断肝组织病理状态的效能评价采用ROC曲线法。结果根据相关分析和方差分析,血浆谷氨酸、丝氨酸、苏氨酸、酪氨酸、蛋氨酸、精氨酸浓度变化可能对肝组织炎症活动度有诊断意义,其诊断轻度炎症(分级≥G2)和中度炎症(分级≥G3)的ROC曲线下面积的95%CI分别为0.541~0.756、0.512~0.717、0.517~0.719、0.615~0.804、0.535~0.741、0.543~0.756和0.548~0.733、0.635~0.803、0.631~0.801、0.606~0.785、0.523~0.709、0.484~0.671;血浆丝氨酸、酪氨酸浓度可能对肝组织纤维化程度有诊断意义,其诊断显著纤维化(分期≥S2)ROC曲线下面积的95%CI为0.495~0.719、0.477~0.679,诊断严重纤维化(分期≥S3)和肝硬化(分期=S4)ROC曲线下面积的95%CI分别为0.543~0.722、0.548~0.728和0.526~0.733、0.523~0.734。结论虽然一些血浆氨基酸浓度随肝组织炎症活动度和纤维化程度的增加而出现定向变化,但不能作为诊断慢性乙型肝炎肝组织病理状态的稳定和可靠指标。
