BACKGROUND AND AIMS
Direct oral anticoagulants (DOACs) may simplify management of Budd-Chiari syndrome (BCS). Here, we report our experience with off-label use of DOACs for anticoagulation in BCS.
METHODS
The safety of DOAC vs vitamin K antagonist treatment as well as associated clinical outcomes were retrospectively assessed in 47 BCS patients treated at 6 Austrian centers.
RESULTS
Mean age at study inclusion was 37.9 ± 14.0 years and mean Model for End-Stage Liver Disease was 13.1 ± 5.1. Overall, 63.8% (n = 30) of patients had decompensated liver disease, and 87.2% (n = 41) showed clinical signs of portal hypertension. During a median follow-up of 82.5 (interquartile range, 43.1-121.8) months, 43 (91.5%) patients received anticoagulation alone or following interventional treatment, including 22 (46.8%) patients treated with DOACs (edoxaban: 10, apixaban: 4, rivaroxaban: 3, dabigatran: 3, more than one DOAC sequentially: 2) for a median of 24.4 (interquartile range, 5.7-35.1) months. While 72.7% (n = 16 of 22) of patients were switched from low-molecular-weight heparin (n = 12) or vitamin K antagonist (n = 4) to DOAC after disease stabilization or improvement, 27.3% (n = 6 of 22) of BCS patients were initially treated with DOAC. Complete response (European Association for the Study of the Liver criteria) was achieved or maintained in 14 (63.6%) of 22 patients, with ongoing response in 2 patients, while disease progressed in 6 patients (including 2 patients with hepatocellular carcinoma). Four major spontaneous bleedings (18.2%; incidence rate 8.8 per 100 patient-years; n = 2 upper gastrointestinal bleeding, n = 1 lower gastrointestinal bleeding, n = 1 hepatocellular carcinoma rupture), 7 minor bleedings, and 1 major procedure-related bleeding (4.5%; 2.2 per 100 patient-years) occurred during DOAC therapy. Overall transplant-free survival was 91.6% at 5 years.
CONCLUSIONS
DOACs seem to be effective and safe for long-term anticoagulation in patients with BCS, but confirmation by larger prospective studies is needed.
背景与目的
直接口服抗凝剂（DOAC）可能简化布加氏综合征（BCS）的管理。在此，我们报告了我们在 6 个奥地利中心使用 DOAC 进行 BCS 抗凝的经验。
方法
回顾性评估了 47 例在 6 个奥地利中心接受治疗的 BCS 患者中 DOAC 与维生素 K 拮抗剂治疗的安全性以及相关临床结局。
结果
研究纳入时的平均年龄为 37.9 ± 14.0 岁，终末期肝病模型平均为 13.1 ± 5.1。总体而言，63.8%（n=30）的患者存在肝功能失代偿，87.2%（n=41）存在门静脉高压的临床征象。中位随访 82.5（四分位间距 43.1-121.8）个月期间，43（91.5%）例患者接受了单独抗凝或介入治疗，其中 22（46.8%）例患者接受了 DOAC 治疗（依度沙班 10 例，阿哌沙班 4 例，利伐沙班 3 例，达比加群 3 例，序贯使用两种 DOAC 各 2 例），中位治疗时间为 24.4（四分位间距 5.7-35.1）个月。在疾病稳定或改善后，72.7%（n=16/22）的患者从低分子肝素（n=12）或维生素 K 拮抗剂（n=4）转换为 DOAC，27.3%（n=6/22）的 BCS 患者初始即接受 DOAC 治疗。22 例患者中，14 例（63.6%）达到或维持完全缓解（欧洲肝脏研究协会标准），2 例患者持续缓解，6 例患者疾病进展（包括 2 例肝细胞癌患者）。在 DOAC 治疗期间，4 例发生自发性大出血（18.2%；发生率 8.8 例/100 患者年；n=2 例上消化道出血，n=1 例下消化道出血，n=1 例肝细胞癌破裂），7 例发生小出血，1 例发生大的与操作相关的出血（4.5%；2.2 例/100 患者年）。5 年时无移植生存为 91.6%。
结论
DOAC 似乎对 BCS 患者的长期抗凝有效且安全，但需要更大规模的前瞻性研究来证实。
