Background: Recipient hepatitis C virus (HCV) seropositivity has been associated with inferior outcomes in renal transplantation (RTx). We sought to determine whether donor HCV+ status influenced the incidence of rejection, liver dysfunction, and graft survival in HCV+ recipients.
Methods: We reviewed 44 HCV+ recipients (R+) receiving RTx from HCV+ (D+) and HCV- (D-) donors between February 1991 and September 1996. All patients were followed to the end of the study period (mean=36 months, range=12-60 months). We compared the R+ group with a demographically matched cohort of 44 HCV- recipients (R-).
Results: Of the 44 R+, 25 (57%) had a total of 48 rejection episodes. Among the 44 R-, 32 (73%) had 58 rejection episodes (P>0.1). Within the R+ group, 28 were D+/R+; of these 14 (50%) had 27 rejection episodes, whereas among the 16 D-/R+, 11 (68%) had 21 rejection episodes (P>0.3). Graft and patient survival was similar in both the groups (86.4% and 91%, respectively). Liver dysfunction was slightly increased in the R+ group (4/44 vs. 0/44, P>0.1), with one death due to liver failure in this group.
Conclusion: Donor HCV+ status had no influence on outcomes in HCV+ recipients after kidney transplantation in the short term. The incidence of rejection, graft loss, and mortality was comparable between the D+/R+ and D-/R+ groups. Furthermore, rejection, graft loss, and death were identical in R+ and R-groups throughout the 5-year study period. We therefore conclude that HCV+ recipients can safely receive kidney transplants without concern about donor HCV status or fear of adverse events from their own HCV+ status.
