ALT与AST作为诊断肝功能损伤的敏感指标,在临床诊断中具有十分重要的作用。这两种转氨酶最初以其形成的产物命名,分别为谷丙转氨酶(SGPT)与谷草转氨酶(SGOT),然而在1961年,国际生物化学协会对这些命名进行了修改,它们分别被命名为ALT与AST[5]。 AST是一种I类磷酸吡哆醛依赖的酶,存在于细胞...

ALT 和天冬氨酸转氨酶(aspartate aminotransferase,AST)曾用于筛查血制品是否携带 HCV(以参考上限作为阈值),但筛查阴性的血制品仍导致 0.58% 的感染率[31],同时也有筛查阳性的血制品的浪费。如今,HCV 抗体检测已普及使用,因此基于 ALT 和...

the severity of cirrhosis is measured by the level of the ratio, implying that patients of cirrhosis with a high AST:ALT ratio would probably have a more advanced case of cirrhosis. On the other hand, patients with acute viral hepatitis often have a very low AST:ALT...
AST:天冬氨酸转氨酶;ALT:谷丙氨酸转氨酶;CHB:慢性乙型肝炎;HBV:乙型肝炎病毒;HBeAg:乙型肝炎e抗原;NK:自然杀伤细胞;qHBsAg:乙型肝炎表面抗原定量;ULN:正常上限。 除治疗组肝脏炎症分级较高外,两组间基线参数无显著性差异。治疗组基线HBV DNA为7.99lgIU/ml,对照组为8.53lgIU/ml。治疗组基线ALT为43U/L,对照组为...
AST ALT ratio > 2 strongly suggests alcoholic hepatitis - an inflammation caused by the consumption of too many units of alcohol for a regular period of time. Too high AST ALT ratio with low levels of AST and ALT. Can be caused by factors located outside of the liver, such as hemolysis...

After excluding AST/ALT ratio, multivariate Cox regression analysis showed that high nuclear grade ( HR=5.836, 95% CI 1.867-18.240, P=0.002) and high AST ( HR=1.040, 95% CI 1.017-1.062, P<0.001) were associated with poor CSS. ConclusionsIn patients with non-metastatic renal cell ...
