End-stage liver disease secondary to hepatitis C virus (HCV) infection is the leading indication for liver transplantation in the United States. Recurrence of HCV infection is nearly universal. We studied the patients enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Liver Transplantation Database to determine whether pretransplantation patient or donor variables could identify a subset of HCV-infected recipients with poor patient survival. Between April 15, 1990, and June 30, 1994, 166 HCV-infected and 509 HCV-negative patients underwent liver transplantation at the participating institutions. Median follow-up was 5.0 years for HCV-infected and 5.2 years for HCV-negative recipients. Pretransplantation donor and recipient characteristics, and patient and graft survival, were prospectively collected and compared. Cumulative patient survival for HCV-infected recipients was similar to that of recipients transplanted for chronic non-B-C hepatitis, or alcoholic and metabolic liver disease, better than that of patients transplanted for malignancy or hepatitis B (P = .02 and P = .003, respectively), and significantly worse than that of patients transplanted for cholestatic liver disease (P = .001). Recipients who had a pretransplantation HCV-RNA titer of > or = 1 x 10(6) vEq/mL had a cumulative 5-year survival of 57% versus 84% for those with HCV-RNA titers of < 1 x 10(6) vEq/mL (P = .0001). Patient and graft survival did not vary with recipient gender, HCV genotype, or induction immunosuppression regimen among the HCV-infected recipients. While long-term patient and graft survival following liver transplantation for end-stage liver disease secondary to HCV are generally comparable with that of most other indications, higher pretransplantation HCV-RNA titers are strongly associated with poor survival among HCV-infected recipients.
丙型肝炎病毒(HCV)感染所致终末期肝病是美国肝移植的主要适应证。HCV感染复发几乎普遍存在。我们研究了国立糖尿病、消化和肾脏疾病研究所肝移植数据库中的患者,以确定移植前患者或供体变量是否能识别出患者生存率低的HCV感染受者亚组。在1990年4月15日至1994年6月30日期间,166例HCV感染患者和509例HCV阴性患者在参与研究的机构接受了肝移植。HCV感染受者的中位随访时间为5.0年,HCV阴性受者为5.2年。前瞻性收集并比较了移植前供体和受者的特征以及患者和移植物的生存率。HCV感染受者的累积患者生存率与因慢性非B-C型肝炎、酒精性和代谢性肝病接受移植的受者相似,优于因恶性肿瘤或乙型肝炎接受移植的患者(分别为P = 0.02和P = 0.003),且显著低于因胆汁淤积性肝病接受移植的患者(P = 0.001)。移植前HCV-RNA滴度≥1×10⁶ vEq/mL的受者5年累积生存率为57%,而HCV-RNA滴度<1×10⁶ vEq/mL的受者为84%(P = 0.0001)。在HCV感染受者中,患者和移植物的生存率并不随受者性别、HCV基因型或诱导免疫抑制方案而变化。虽然HCV所致终末期肝病肝移植后的长期患者和移植物生存率通常与大多数其他适应证相当,但移植前较高的HCV-RNA滴度与HCV感染受者的低生存率密切相关。
