The virologic and histologic outcomes of a hepatitis C virus (HCV)-infected liver graft into an HCV-negative recipient are not well understood. We aimed to evaluate the sustained virologic response (SVR) rate and the liver histology at 1 year post-Orthotopic liver transplantation (OLT) with an HCV-infected graft.
A total of 33 patients received the HCV antibody (Ab)+/nucleic acid amplification test (NAT)+ graft. Of these patients, 23 were HCV-negative recipients and 10 were HCV-positive recipients. The 1-year biopsy data were available for 24 patients: 15 patients in HCV-negative group who received an HCV Ab+/NAT+graft and 9 patients in HCV-positive group who received an HCV Ab+/NAT+ graft. Patients with (+) HCV ribonucleic acid (RNA) were started on direct-acting antiviral (DAA) treatment approximately 107 days after OLT using either a Glecaprevir-Pibrentasvir or Sofosbuvir-Velpatasvir or Sofosbuvir-Ledipasvir.
All patients (n = 33) were treated with DAA and achieved SVR. The 1-year post-OLT liver biopsies were available in 24 patients: 9 patients had F1 and F2 fibrosis and 17 patients had minimal to moderate inflammation. There was no statistical difference in fibrosis and inflammation between the HCV-negative vs. HCV-positive recipients. All patients who received the NAT+ graft developed viremia and subsequently achieved SVR with treatment.
At 1 year protocol liver biopsy, patients had inflammation consistent with viral hepatitis despite the successful eradication of HCV.
HCV 感染的肝移植物移植到 HCV 阴性受者的病毒学和组织学结果尚不清楚。我们旨在评估 HCV 感染的移植物肝移植(OLT)后 1 年的持续病毒学应答(SVR)率和肝组织学。
共有 33 例患者接受了 HCV 抗体(Ab)+/核酸扩增试验(NAT)+移植物。其中 23 例为 HCV 阴性受者,10 例为 HCV 阳性受者。24 例患者获得了 1 年活检数据:15 例 HCV 阴性组患者接受 HCV Ab+/NAT+移植物,9 例 HCV 阳性组患者接受 HCV Ab+/NAT+移植物。移植后约 107 天,(+)HCV 核糖核酸(RNA)的患者开始使用 Glecaprevir-Pibrentasvir、Sofosbuvir-Velpatasvir 或 Sofosbuvir-Ledipasvir 进行直接作用抗病毒(DAA)治疗。
所有患者(n=33)均接受 DAA 治疗并获得 SVR。24 例患者获得了 OLT 后 1 年的肝活检:9 例患者存在 F1 和 F2 纤维化,17 例患者存在轻微至中度炎症。HCV 阴性与 HCV 阳性受者的纤维化和炎症无统计学差异。所有接受 NAT+移植物的患者均发生病毒血症,并随后通过治疗获得 SVR。
在 1 年的方案肝活检中,尽管 HCV 已被成功清除,但患者仍存在与病毒性肝炎一致的炎症。
