The growing prevalence of hepatitis C virus (HCV) infection in the general population has resulted in an increased frequency of potential organ donors that carry the virus. Given the significant disparity between organ supply and demand for transplantation, it becomes essential to consider whether livers from anti-HCV-positive donors may be considered suitable for transplantation.
Based on a multicenter European database, 694 patients with HCV-related cirrhosis underwent liver transplantation and 11% of them received the graft from anti-HCV-positive donors. Of this group, we selected 63 patients (study group) and, after a 1:1 case-control approach, compared them with 63 patients that received an anti-HCV-negative donor graft (control group). Only grafts with preperfusion liver biopsy results with a fibrosis score of not more than 1 were used for transplantation.
Patients who received anti-HCV-positive grafts had a cumulative survival rate of 83.6% and 61.7% at 1 and 5 years, respectively, vs. 95.1% and 68.2% for the control group. In comparing overall patient and graft survival, there was no statistically significant difference between the two groups (P=0.22 and 0.11). Recurrence of hepatitis C tended to be more rapid in the group of patients who received anti-HCV-positive grafts, although it did not reach statistical significance (P=0.07).
We do not recommend the indiscriminate use of anti-HCV-positive donors, especially if HCV-RNA positive, as the use of this kind of graft could be linked to an advanced stage of fibrosis, the main risk factor we observed for earlier hepatitis C recurrence.
丙型肝炎病毒(HCV)感染在普通人群中的发病率不断上升,导致潜在的携带病毒的器官供体数量增加。鉴于器官供应与移植需求之间存在显著差异,有必要考虑来自抗-HCV 阳性供体的肝脏是否适合移植。
基于多中心欧洲数据库,694 名丙型肝炎相关肝硬化患者接受了肝移植,其中 11%的患者接受了抗-HCV 阳性供体的移植物。在这一组中,我们选择了 63 名患者(研究组),并采用 1:1 病例对照的方法,将他们与 63 名接受抗-HCV 阴性供体移植物的患者(对照组)进行比较。仅使用预灌注肝活检结果纤维化评分不超过 1 的移植物进行移植。
接受抗-HCV 阳性移植物的患者累积生存率分别为 1 年时 83.6%和 5 年时 61.7%,而对照组分别为 95.1%和 68.2%。在比较两组患者和移植物的总体生存率时,两组之间无统计学差异(P=0.22 和 0.11)。尽管差异无统计学意义(P=0.07),但接受抗-HCV 阳性移植物的患者中丙型肝炎的复发速度往往更快。
我们不建议不加选择地使用抗-HCV 阳性供体,特别是如果 HCV-RNA 阳性,因为使用这种移植物可能与纤维化的晚期有关,这是我们观察到的丙型肝炎复发的主要危险因素。
