Does donor race still make a difference in deceased-donor African-American renal allograft recipients?

BACKGROUND

Prior studies have demonstrated that African-American (AA) donor kidneys are independently associated with an increased risk for graft loss.

METHODS

We examined outcomes in comparable groups of AA deceased-donor (DD) kidney transplant patients receiving an AA donor (n=35) versus a Caucasian donor (C group; n=150) organ.

RESULTS

There were no differences between AA and C groups in patient survival, new-onset diabetes, or BK nephropathy. The AA group demonstrated a significantly higher 6-month and overall incidence of acute rejection (AR), increased cytomegalovirus (CMV) infection, and decreased graft survival. Recurrent or de novo focal segmental glomerulosclerosis (FSGS) accounted for a significantly higher fraction of graft losses in the AA versus C group.

CONCLUSIONS

AA DD renal allograft recipients have equivalent patient but decreased graft survival when transplanted with an AA versus C kidney using current immunosuppression. This may be the result of increased AR, CMV infection, and recurrence/development of FSGS.
