Zepatier是全球第三款突破性鸡尾酒疗法,由Grazoprevir(100 mg,NS3/4A蛋白酶抑制剂)和elbasvir(50 mg,NS5A抑制剂)组成,每日口服一次,疗程共12周。最近的研究证实,合并终末期慢性肾病的1型丙肝患者应用Zepatier治疗安全有效[1]。

为了明确该问题,Roth D等人[1]在欧美等地的68个国际医学中心开展了多中心、3期、双盲研究(C-SURFER研究),证实了Zepatier治疗可使合并4-5期慢性肾病的基因1型HCV患者获得高SVR12率(治疗结束12周时持续病毒学应答)且安全性良好。该研究结果于2015年发表在了医学顶级期刊《Lancet》杂志(IF=47.831)。

注:4期或5期慢性肾病的定义分别是eGFR(根据肾脏病饮食改良[MDRD]-公式4计算)为15–29 mL/min/1.73 m2 和eGFR小于15 mL/min/1.73 m2或者透析。
Roth D等人选择了235例合并4或5期慢性肾病的成年基因1型丙肝患者为研究对象。其中,224例患者随机平分为2组,A组立即给予Zepatier治疗12周;B组先给予安慰剂治疗12周,随访4周后,再给予Zepatier治疗12周;此两组均为盲法,患者不知道自己应用的何种药物。
剩余的11例患者为C组,立即给予Zepatier治疗12周,但此组患者知道自己应用的治疗方案;三组患者治疗结束后均随访24周。通过对A、B两组安全事件发生率的比较可反应Zepatier治疗的安全性,而A、C两组的SVR12可反应Zepatier治疗的疗效。

C-SURFER研究结果:SVR12(%)
既往研究显示,HCV感染并血液透析的患者用干扰素治疗的SVR率为45%[13],但Roth D等人研究发现,Zepatier治疗的122例合并4-5期慢性肾病的1型HCV患者中(其中有6例患者因死亡、失访等原因退出),SVR12率高达99%,远高于既往干扰素的治疗效果。
