Abstract
BACKGROUND- OBJECTIVES: Current evidence based on retrospective and prospective studies demonstrates that donation after circulatory death (DCD) grafts are more susceptible to delayed graft function (DGF) than donation after brain death (DBD) grafts. The short- and long-term survival outcomes of the two cohorts are unclear. Therefore, we performed a systematic review and meta-analysis to estimate the patient and allograft survival outcomes for DCD and DBD in renal transplant surgery. METHODS: Systematic literature searches were conducted by searching various databases. Fixed and random effects models were used to assess the accumulation of evidence over time. RESULTS: The five-year patient survival rate was significantly better in the DBD than in the DCD cohort. Non-significant differences were observed in 1-, 3- and 10-year patient survival and in the 1-, 3-, 5-, and 10-year graft survival rates between the two cohorts. The acute rejection rate was lower in the DCD cohort than in the DBD cohort. Extended criteria of donor status, delayed graft function and primary non-function were significantly higher in the DCD cohort than in the DBD cohort. CONCLUSIONS: This study demonstrates that the short- and long-term survival graft and patient benefits are similar between DCD and DBD kidney transplants. Therefore, large, controlled DCD kidney programmes are urgently needed worldwide in order to increase the number of kidney transplants.
