The study aimed to determine coagulation factor abnormalities in alcoholic liver disease (ALD) and correlate these with severity of liver dysfunction (Child's class) and gastrointestinal (GI) bleeding.
60 patients of ALD (alcohol intake >10years and clinical, biochemical or radiological evidence of chronic liver disease) were included. Patients with Hepatitis B, Hepatitis C, HIV infection, DIC, low platelet count due to other causes, or on drugs which affect coagulation profile were excluded.
Age was 44.42 ± 10.26 years (100% males), 53% in Childs class C. Severity of liver dysfunction showed a significant association (p<0.05) with prolongation of prothrombin time (PT), activated partial thromboplastin time (aPTT) and thrombin time (TT), increasing factor VIII and D-Dimer level, low platelet counts, low protein S and factor VII activity; as well as decreasing fibrinogen levels, protein C and antithrombin (AT) III. GI bleed is associated significantly (p<0.05) with PT >20 sec and decreased plasma fibrinogen levels, while normal protein C, normal AT III, normal factor VII, normal factor VIII, normal TT, increased plasma fibrinogen levels, normal PT and normal platelet count appeared to be protective.
Several coagulation parameters are altered in ALD variably. Alterations in PT, aPTT, TT, factor VIII, D-Dimer, fibrinogen, protein C and AT III levels can be used for grading severity of liver disease. Decreased fibrinogen, protein C activity, AT III activity, factor VII activity, and increased factor VIII activity, are associated with GI bleed.
本研究旨在确定酒精性肝病(ALD)患者的凝血因子异常情况,并将这些异常与肝功能障碍的严重程度(Child分级)及胃肠道(GI)出血相关联。
纳入60例ALD患者(饮酒史>10年且有慢性肝病的临床、生化或影像学证据)。排除患有乙型肝炎、丙型肝炎、HIV感染、弥散性血管内凝血(DIC)、因其他原因导致血小板计数低或正在使用影响凝血指标药物的患者。
患者年龄为44.42±10.26岁(均为男性),53%为Child C级。肝功能障碍的严重程度与凝血酶原时间(PT)延长、活化部分凝血活酶时间(aPTT)延长、凝血酶时间(TT)延长、因子VIII水平升高、D-二聚体水平升高、血小板计数降低、蛋白S降低及因子VII活性降低显著相关(p<0.05);同时与纤维蛋白原水平降低、蛋白C及抗凝血酶(AT)III降低也显著相关。胃肠道出血与PT>20秒及血浆纤维蛋白原水平降低显著相关(p<0.05),而蛋白C正常、AT III正常、因子VII正常、因子VIII正常、TT正常、血浆纤维蛋白原水平升高、PT正常及血小板计数正常似乎具有保护作用。
ALD患者的多种凝血参数存在不同程度的改变。PT、aPTT、TT、因子VIII、D-二聚体、纤维蛋白原、蛋白C及AT III水平的改变可用于评估肝病的严重程度分级。纤维蛋白原降低、蛋白C活性降低、AT III活性降低、因子VII活性降低以及因子VIII活性升高与胃肠道出血相关。
