title: Use of liver grafts from donation after cardiac death donors for recipients with hepatitis C virus.
abstract: Hepatitis C virus (HCV) infection is the most common indication for orthotopic liver transplantation in the United States. Although studies have addressed the use of expanded criteria donor organs in HCV(+) patients, to date the use of liver grafts from donation after cardiac death (DCD) donors in HCV(+) patients has been addressed by only a limited number of studies. This retrospective analysis was undertaken to study the outcomes of DCD liver grafts used in HCV(+) recipients. Seventy-seven HCV(+) patients who received DCD liver grafts were compared to 77 matched HCV(+) patients who received donation after brain death (DBD) liver grafts and 77 unmatched non-HCV patients who received DCD liver grafts. There were no differences in 1-, 3-, and 5-year patient or graft survival among the groups. Multivariate analysis showed that the Model for End-Stage Liver Disease score [hazard ratio (HR) = 1.037, 95% confidence interval (CI) = 1.006-1.069, P = 0.018] and posttransplant cytomegalovirus infection (HR = 3.367, 95% CI = 1.493-7.593, P = 0.003) were significant factors for graft loss. A comparison of the HCV(+) groups for fibrosis progression based on protocol biopsy samples up to 5 years post-transplant did not show any difference; in multivariate analysis, HCV genotype 1 was the only factor that affected progression to stage 2 fibrosis (genotype 1 versus non-1 genotypes: HR = 2.739, 95% CI = 1.047-7.143, P = 0.040). In conclusion, this match-controlled, retrospective analysis demonstrates that DCD liver graft utilization does not cause untoward effects on disease progression or patient and graft survival in comparison with DBD liver grafts in HCV(+) patients.
