JGH OPEN:丙氨酸转氨酶长期> 1000 IU / L的后果

2020-04-12 MedSci原创 MedSci原创

丙氨酸氨基转移酶(ALT)的明显升高是由基础疾病引起的,这些病理改变包括肝缺血,药物/毒素,病毒性肝炎,以及罕见的自身免疫性肝炎。

背景与目标:丙氨酸氨基转移酶(ALT)的明显升高是由基础疾病引起的,这些病理改变包括肝缺血,药物/毒素,病毒性肝炎,以及罕见的自身免疫性肝炎。本项研究的目的是确定导致ALT大于1000IU/L的病因相对发生率,以及临床预后的因素。

方法:研究人员在2013年1月至2015年12月之间,对澳大利亚所有大型教学医院网络中所有ALT水平高于1000IU/L的成年患者进行了一项回顾性队列研究。多变量logistic回归分析用于确定病因和死亡率的预测指标。

结果:有287名患者的ALT水平高于1000IU/L。最常见的原因是缺血(44%),药物/毒素(19%),胆道梗阻(16%)和病毒性肝炎(7%)。诊断为缺血性肝炎的独立预测因素包括:低血压(29.2; 8.2-104.7),冠状动脉疾病(12.9; 1.7–98.9),充血性心力衰竭(7.8; 1.2–49.2),糖尿病(7.4; 1.6–33.9),代谢性酸中毒(6.2; 2.0–19.4),γ-谷氨酰转移酶<135 IU / L(5.1; 1.5–17.6) )和白蛋白<34g/L(3.4; 1.1-11.0)。全天28天致死的独立危险因素包括:败血性休克(14.7; 4.3-50.7),代谢性酸中毒(7.3; 2.5-21.3),COPD病史(5.4; 1.6-17.8),心源性休克(4.3; 1.6–11.7),

结论:缺血性肝炎是ALT水平高于1000IU/L的最常见病因,并且与高死亡率相关。

综述:慢性丙肝患者的规范化治疗

       我国是一个乙型肝炎(简称乙肝)大国,临床医师及公众对乙肝的认知度、警觉度均较高,而丙型肝炎(简称丙肝)却往往被忽视,以致其早期发现率和诊断率均较低。事实上,丙肝在世界范围呈广泛流行,是欧美及日本等国家终末期肝病的最主要原因。在我国一般人群中,抗-HCV阳性率也有0.43%。丙肝病毒(HCV)感染的慢性化率(50%~85%)远
