Living donor liver transplantation versus donation after brain death and donation after circulatory death liver transplantation in the US

Abstract

While previous research has compared outcomes between living donor liver transplantation (LDLT) and deceased donor liver transplantation, evidence is lacking regarding how donation after circulatory death (DCD) vs donation after brain death (DBD) affects this comparison. Using data from the Scientific Registry of Transplant Recipients for adults listed for liver transplant from 2012 to 2018, we compared 5-year patient and graft survival, readmissions, posttransplant chronic kidney disease (CKD), and return to work for 25,151 patients who underwent LDLT (1223 [4.9%]), DCD-LT (1431 [6.4%]), and DBD-LT (22,497 [89.4%]). LDLT recipients were significantly more likely to have a Model for End-Stage Liver Disease (MELD) score < 15 and to be working prior to transplant (P < 0.001 for both). At 5 years posttransplant, LDLT recipients had significantly more readmissions, but significantly less CKD and better survival than DBD-LT and DCD-LT recipients, as well as significantly better graft survival than DCD-LT recipients (P ≤ 0.01 for all). Significantly more LDLT recipients also returned to work for income (P < 0.01). This study shows a clear advantage of LDLT vs DCD-LT. This information should be weighed in transplantation decisions for patients such as those with low MELD scores who will realistically only be considered for DCD-LT.
