Impact of Donation After Circulatory Death Allografts on Outcomes After Liver Transplant for Hepatitis C: A Single-Center Experience and Review of the Literature

Objectives: We investigated the impact of liver transplant from donors after circulatory death on incidence and severity of recurrent hepatitis C virus infection, graft and patient survival and aimed to identify predictors of outcomes. Materials and Methods: We retrospectively reviewed all liver transplants performed at a single center (July 2007-February 2014). Patients with hepatitis C who underwent liver transplant from donors after circulatory death (group 1) were compared with hepatitis C patients who received grafts from donors after brain death (group 2) and patients without hepatitis C who received grafts from donors after circulatory death (group 3). We used the Kaplan-Meier method for survival analysis and performed a multivariable analysis for predictors of outcomes using Cox regression. Competing risk was used to analyze hepatitis C recurrence. Results: Of 196 patients, 107 were included: 25 in group 1, 46 in group 2, and 36 in group 3. All 3 groups were comparable, except for longer cold ischemia time (P <.01) in group 1, lower Model for End-Stage Liver Disease score at transplant in groups 1 and 3 (P <.01), and greater proportion of recipients with hepatocellular carcinoma in groups 1 and 2 (P =.02). Hepatitis C recurrence and severe recurrence at 1 and 3 years were higher in group 1 ( but not statistically significant). Severe recurrence was noted in 17% versus 8% at 1 year (P =.12) and 30% versus 14% at 3 years (P =.08). Graft and patient survival rates at 1, 3, and 5 years were comparable in all 3 study groups. Conclusions: Recurrent hepatitis C, including severe recurrence, was greater following donation after circulatory death compared with donation after brain death liver transplant. However, graft survival and patient survival were comparable, including in recipients of donation after circulatory death grafts without hepatitis C.
