BACKGROUND & AIMS: Studies of the effects of direct oral anticoagulants (DOACs) in patients with cirrhosis have been limited by their small sample size, inclusion of patients with well-compensated cirrhosis, short follow-up times, inadequate validation of cirrhosis diagnoses, and non-standard definitions of bleeding. We aimed to systematically determine the characteristics, indications, and outcomes of patients with cirrhosis of all severity classes who received DOACs.
We performed a retrospective study of 138 patients with confirmed cirrhosis (93 with Child-Turcotte-Pugh scores of B or C) at a single center who started DOAC therapy (58,984 person-days; median, 181 days per patient) from September 2011 through April 2019. We collected data on clinical characteristics, indications for DOAC use, and outcomes. Standardized and validated definitions for bleeding complications were used.
Twenty-nine patients (21%) stopped therapy due to a diagnosis of or perceived bleeding. The most common bleeding events were non-variceal upper and lower intestinal bleeding. No pretreatment laboratory parameters were associated with bleeding while patients received treatment, including platelet count (P = .50), international normalized ratio (P = .34), creatinine (P = .27), and model for end-stage liver disease score (P = .22). Frequency of bleeding events related to DOAC did not differ significantly among patients of different Child-Turcotte-Pugh classes (P = .81), DOAC indications (P = .60), or DOAC dosages (P = .10). Higher proportions of patients with hepatocellular carcinoma (P = .01) had major bleeding while receiving.
Patients with decompensated cirrhosis have significant bleeding and rates of discontinuation of DOACs when they take them long term. Pretreatment laboratory parameters, DOAC dose, and Child-Turcotte-Pugh class were not associated with bleeding; hepatocellular carcinoma was associated with major bleeding.
关于直接口服抗凝剂(DOAC)在肝硬化患者中的作用的研究受到样本量小、纳入代偿良好的肝硬化患者、随访时间短、肝硬化诊断验证不足以及出血定义不标准等因素的限制。我们旨在系统地确定所有严重程度级别的肝硬化患者接受 DOAC 治疗的特征、适应证和结局。
我们对单中心 138 例经证实的肝硬化患者(93 例患者的 Child-Turcotte-Pugh 评分 B 或 C)进行了回顾性研究,这些患者自 2011 年 9 月至 2019 年 4 月开始接受 DOAC 治疗(58984 人日;每位患者的中位数为 181 天)。我们收集了临床特征、DOAC 使用适应证和结局的数据。使用标准化和验证的出血并发症定义。
29 例患者(21%)因诊断或认为出血而停止治疗。最常见的出血事件是非静脉曲张性上消化道和下消化道出血。在患者接受治疗期间,没有任何预处理的实验室参数与出血相关,包括血小板计数(P=0.50)、国际标准化比值(P=0.34)、肌酐(P=0.27)和终末期肝病模型评分(P=0.22)。不同 Child-Turcotte-Pugh 级别的患者(P=0.81)、DOAC 适应证(P=0.60)或 DOAC 剂量(P=0.10)之间,DOAC 相关出血事件的频率无显著差异。接受治疗的肝细胞癌患者(P=0.01)发生大出血的比例较高。
失代偿期肝硬化患者长期服用 DOAC 时会发生严重出血和停药。预处理实验室参数、DOAC 剂量和 Child-Turcotte-Pugh 分级与出血无关;肝细胞癌与大出血有关。
