Impact of donation after circulatory death donor allografts on outcomes following liver transplantation for fulminant hepatic failure in the United States.

Limited data exist regarding the impact of donation after circulatory death (DCD) allografts on outcomes following liver transplantation in fulminant hepatic failure (FHF). Utilizing the Scientific Registry of Transplant Recipients (SRTR), we compared outcomes after DCD in FHF to donation after brain death (DBD) in FHF and DCD in non-FHF over a 15-year period. Primary outcome measures were graft and patient survival. A total of 117, 3437, and 4379 recipients underwent DCD-FHF, DBD-FHF and DCD-non-FHF, respectively. One-year graft survival in DCD-FHF was inferior to DBD-FHF (72.9% vs. 83.8%, p = .002), but comparable to DCD-non-FHF (72.9% vs. 82.7%, p = .23). However, 3- and 5-year graft survival in DCD-FHF were comparable to DBD-FHF (67.9 vs. 77.6%, p = .63; 57.8% vs. 73.2%, p = .27) and DCD-non-FHF (67.9% vs. 72.9%, p = .44; 57.8% vs. 66.6%, p = .06). One-, 3-, and 5-year patient survival were also comparable among the three groups. Graft and patient survival in DCD-FHF improved over the study period. Multivariable analysis identified recipient age, male gender, African American ethnicity, donor age, and cold ischemia time as predictors of graft and patient survival in FHF, while DCD status was only predictive of graft survival. Long-term graft survival and patient survival in DCD-FHF are comparable to DBD-FHF and DCD-non-FHF. Consideration of DCD in FHF could help expand the donor pool in this subset of critically ill patients.
