Lung transplant outcome following donation after euthanasia.
Journal Contribution - Journal Article
BACKGROUND: Organ transplantation is hampered by shortage of suitable organs. In countries with a legal framework, organ donation following euthanasia is an option labeled "donation after cardio-circulatory death category V" (DCD-V). We describe our experience with lung transplantation (LTx) after euthanasia and evaluate post-transplant outcome using a matched comparison to DCD-III (withdrawal from life-sustaining therapy) and donation after brain death (DBD). METHODS: All bilateral LTx between 2007 and 2020 were retrospectively analyzed. Matching was performed for recipient age and gender, indication for LTx, mean pulmonary artery pressure, extracorporeal life support, and donor age, which resulted in 1:2 DCD-III and 1:3 DBD matching. Primary graft dysfunction (PGD), chronic lung allograft dysfunction (CLAD), and patient survival were analyzed. RESULTS: A total of 769 LTx were performed of which 22 from DCD-V donors (2.9%). Thirteen women and 9 men expressed their wish to become organ donor after euthanasia. Euthanasia request was granted for irremediable neuromuscular (N = 9) or psychiatric (N = 8) disorder or unbearable and unrecoverable pain (N = 5). PGD (grade 3, within 72 hours post-transplant) was 23.8% in the DCD-V cohort, which is comparable to DCD-III (27.9%; p = 1.00) and DBD (32.3%; p = .59). CLAD-free 3- and 5-year survival were 86.4% and 62.8%, respectively, and comparable to DCD-III (74.4% and 60.0%; p = .62) and DBD (72.6% and 55.5%; p = .32). Five-year patient survival was 90.9%, not significantly different from both DCD-III (86.0%; p = 1.00) and DBD (78.1%; p = .36). CONCLUSIONS: We observed that LTx with DCD-V allografts is feasible and safe, yielding no evidence for differences in short- and long-term outcome compared to matched cohorts of DCD-III and DBD.
