Hepatitis C recurrence continues to present a major challenge in liver transplantation (LT). Approximately 10% of hepatitis C virus (HCV)-positive recipients will develop fibrosing cholestatic hepatitis (FCH) after LT. FCH is clinically characterized as marked jaundice with cholestatic hepatic dysfunction and high titers of viremia. Pathologically, FCH manifests as marked hepatocyte swelling, cholestasis, periportal peritrabecular fibrosis and only mild inflammation. This progressive form usually involves acute liver failure, and rapidly results in graft loss. A real-time and precise diagnosis based on histopathological examination and viral measurement is indispensable for the adequate treatment of FCH. Typical pathological findings of FCH are shown. Currently, carefully selected combinations of direct-acting antivirals (DAAs) offer the potential for highly effective and safe regimens for hepatitis C, both in the pre- and post-transplant settings. Here, we review FCH caused by HCV in LT recipients, and current strategies for sustained virological responses after LT. Only a few cases of successfully treated FCH C after LT by DAAs have been reported. The diagnostic findings and therapeutic dilemma are discussed based on a literature review.
丙型肝炎复发仍是肝移植(LT)中的一个重大挑战。大约10%的丙型肝炎病毒(HCV)阳性受者在肝移植后会发生纤维性胆汁淤积性肝炎(FCH)。FCH的临床特征为伴有胆汁淤积性肝功能障碍的明显黄疸和高滴度病毒血症。病理上,FCH表现为明显的肝细胞肿胀、胆汁淤积、汇管区小梁周围纤维化且仅有轻度炎症。这种进行性形式通常会导致急性肝衰竭,并迅速导致移植物丢失。基于组织病理学检查和病毒检测的实时精确诊断对于FCH的适当治疗必不可少。展示了FCH的典型病理表现。目前,精心挑选的直接抗病毒药物(DAA)组合为移植前和移植后丙型肝炎的高效安全治疗方案提供了可能。在此,我们回顾肝移植受者中由HCV引起的FCH以及肝移植后实现持续病毒学应答的当前策略。仅有少数关于肝移植后通过DAA成功治疗FCH C的病例报道。基于文献综述讨论了诊断结果和治疗困境。
