There is convincing evidence that primary sclerosing cholangitis (PSC) recurs after deceased donor liver transplantation with an incidence of about 20% after 5 years. This review summarizes data regarding recurrent disease in the setting of live donor liver transplantation.
End-stage liver disease secondary to PSC accounts for less than 3% of all live donor liver transplantations worldwide. Therefore, there are only few data regarding recurrent disease in this setting available, mainly from Japanese transplant centers. Based on these studies, however, only including a small number of patients, recurrent disease was diagnosed in 25-67% of transplant recipients after a mean follow-up of 34 months following transplantation. Cytomegalovirus infection in the early postoperative phase and biologically related donors were found to be statistically significant risk factors for disease recurrence. More than one third of patients with recurrent disease either died or developed graft failure.
These data suggest that patients with PSC undergoing live donor liver transplantation, especially with biologically related donors, may have a higher risk to develop recurrent disease compared with the deceased donor setting. However, this fact has to be interpreted with great caution, primarily due to the rather small number of patients. Further studies analyzing pooled data of all transplant centers performing live donor liver transplantations are needed to confirm these findings.
有确凿证据表明原发性硬化性胆管炎(PSC)在接受尸体供肝移植后会复发,5 年后的复发率约为 20%。本文综述了活体供肝移植背景下疾病复发的数据。
PSC 导致的终末期肝病在全球所有活体供肝移植中所占比例不足 3%。因此,关于该背景下疾病复发的数据非常有限,主要来自日本移植中心。然而,基于这些研究,包括的患者数量较少,在移植后平均随访 34 个月后,有 25%-67%的移植受者被诊断为疾病复发。术后早期巨细胞病毒感染和生物相关供体被发现是疾病复发的统计学显著危险因素。超过三分之一的复发病例患者死亡或发生移植物失功。
这些数据表明,与尸体供肝移植相比,PSC 患者接受活体供肝移植,尤其是接受生物相关供体的患者,可能有更高的疾病复发风险。但必须谨慎解读这些数据,主要是因为患者数量较少。需要进一步分析所有开展活体供肝移植的移植中心的汇总数据来证实这些发现。
