BACKGROUND/AIMS: Direct-acting antivirals (DAAs) play a key role in the eradication of hepatitis C virus (HCV) infection. However, limited data are available on DAA for treating HCV infection in hemodialysis (HD) patients. This study was to evaluate the pharmacokinetic characteristics and effectiveness of daclatasvir/sofosbuvir (DAC/SOF) and ledipasvir/SOF (LDV/SOF) in HD patients.
Seven patients were given SOF coadministered with DAC or LDV once daily for 12 weeks. The plasma concentrations of SOF007, DAC, and LDV were determined by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry.
A sustained virologic response in week 12 (SVR12) was achieved in 6 (100%) patients, except for 1 patient dying due to severe cerebral hemorrhage not related to antiviral therapy. The extraction ratio of SOF007 was 66.67%, and the estimated HD clearance of SOF007 was 5.65 L/h.
The combination of SOF with either DAC or LDV is well tolerated and offers high SVR12 in HD patients.
背景/目的：直接作用抗病毒药物（DAAs）在消除丙型肝炎病毒（HCV）感染方面发挥着关键作用。然而，关于 DAA 治疗血液透析（HD）患者 HCV 感染的数据有限。本研究旨在评估达卡他韦/索磷布韦（DAC/SOF）和来迪派韦/索磷布韦（LDV/SOF）在 HD 患者中的药代动力学特征和疗效。
7 名患者每日一次给予 SOF 联合 DAC 或 LDV 治疗 12 周。采用高效液相色谱-电喷雾串联质谱法测定 SOF007、DAC 和 LDV 的血浆浓度。
6 名（100%）患者获得了第 12 周持续病毒学应答（SVR12），除了 1 名因与抗病毒治疗无关的严重脑出血死亡的患者。SOF007 的提取率为 66.67%，估计 SOF007 的 HD 清除率为 5.65 L/h。
SOF 联合 DAC 或 LDV 治疗具有良好的耐受性，并可在 HD 患者中获得高 SVR12。
