Gut:乙型肝炎相关慢加急性肝衰竭新的诊断标准和预后评分系统

2017-09-28 MedSci MedSci原创

无论肝硬化是否存在,TB≥12 mg/ dL和INR≥1.5的慢性乙型肝炎患者都应该被诊断为ACLF。近20%的HBV-ACLF患者被诊断出,从而增加了他们获得及时治疗管理的机会。

背景和目的:不考虑病因,仅依据肝硬化来定义慢加急性肝衰竭(ACLF),是存在争议的。本研究旨在阐明乙型肝炎相关慢加急性肝衰竭的临床病理特征,为这些患者制定新的诊断标准和预后评分系统。

方法:本研究是一项前瞻性研究,纳入中国13个肝病中心的1322例住院患者。这些患者因慢性乙型病毒性肝炎导致急性失代偿性肝硬化和严重肝损伤。采用这些患者的临床数据制定新的诊断标准和预后评分系统。

结果:采用排除肝硬化的慢性肝功能衰竭联合标准,391例患者被确定为ACLF患者,其中,92例患者是非肝硬化HBV相关慢加急性肝衰竭(HBV-ACLF),271例患者是硬化性HBV相关慢加急性肝衰竭,28例患者非HBV肝硬化性慢加急性肝衰竭(非HBV-ACLF)。HBV-ACLF患者短期(28/90天)死亡率显著高于非HBV-ACLF患者。总胆红素(TB)≥12 mg/dL和国际标准化比率(INR)≥1.5,作为诊断HBV-ACLF的附加指标;由HBV导致疾病,19.3%的患者被诊断为ACLF。新的预后评估系统为:0.741xINR+0.523xHBV-SOFA+0.026xage+0.003xTB。新的预后评估系统在评估早期死亡率方面,优于其他5个依靠发现和外部验证的系统。

无论肝硬化是否存在,TB≥12 mg/ dL和INR≥1.5的慢性乙型肝炎患者都应该被诊断为ACLF。近20%的HBV-ACLF患者被诊断出,从而增加了他们获得及时治疗管理的机会。
