Transplantation of kidneys from paediatric DCD donors: a comparison with DBD donors.

ABSTRACT

BACKGROUND: Although acceptable outcomes have been reported in kidney transplantation from donation after cardiac death (DCD), little is known about kidney transplantation from paediatric DCD. The objective of this study was to compare the outcome of kidney transplantation using paediatric DCD with the outcome of paediatric donation after brain death (DBD). METHODS: Recipients from DCD and DBD donors <18 years of age transplanted in the Netherlands between January 1981 and July 2006 were included in this study. Ninety-one patients were transplanted with kidneys from paediatric DCD donors and 405 patients received grafts from paediatric DBD donors. RESULTS: Grafts from DCD donors were associated with higher percentage of primary non-function (9 versus 2%, P < 0.01) and delayed graft function (48 versus 8%, P < 0.001) compared with DBD donor grafts. Estimated glomerular filtration rate did not differ between groups (57 ± 17 versus 58 ± 21 mL/min at 1 year and 62 ± 14 versus 57 ± 22 mL/min at 5 years, respectively). After correction for confounding variables, the risk of graft failure was higher in the DCD group [hazard ratio 2.440 (95% confidence interval (CI) 1.280-4.650; P = 0.007]. Patient survival, however, was similar between groups [hazard ratio 1.559 (95% CI 0.848-2.867; P = 0.153)]. CONCLUSIONS: Paediatric DCD kidneys represent a valuable source of donor kidneys that has not been fully utilized. Although transplantation of paediatric DCD kidneys is associated with a higher risk of graft failure than transplantation of paediatric DBD kidneys, results are comparable with adult donors. We therefore conclude that paediatric DCD kidneys can be safely added to the donor pool.
