Impact of Hepatitis C Virus on Renal Transplantation: Association With Poor Survival

Data concerning the effect of hepatitis C virus (HCV) infection on the long-term outcome of patient and allograft survival are conflicting. We performed a retrospective study including all renal transplant recipients who underwent the procedure at our center between July 1983 and December 2004. We compared HCV-positive (n = 155) versus HCV-negative (n = 1044) recipients for the prevalence of anti-HCV, patient/donor characteristics, and graft/patient survival. The prevalence of HCV-positive patients was 12%. The anti-HCV positive recipients displayed a longer time on dialysis (P < .001), more blood transfusions prior to transplant (P < .001), and a higher number of previous transplants (P < .001). There were no differences in the incidence of acute rejection between the two groups. Patient (P = .006) and graft survival (P = .012) were significantly lower in the HCV-positive than the HCV-negative group. Graft survival censored for patient death with a functioning kidney did not differ significantly between HCV-positive and HCV-negative recipients (P = .083). Death from infectious causes was significantly higher among the HCV-positive group (P = .014). We concluded that HCV infection had a significant detrimental impact on patient and renal allograft prognosis. Death from infectious causes was significantly more frequent among HCV-positive than the non-HCV population.
