Abstract: Introduction: Although African Americans (AA) are considered higher risk kidney donors than Caucasians, limited data are available regarding outcomes of AA donors. Methods: We performed a single‐center retrospective review of all kidney donors from 1993 to 2007 and evaluated race/ethnic differences in post‐donation changes in renal function, incident proteinuria, and systolic blood pressure (SBP) using linear mixed models. Results: A total of 336 kidney donors (63 AA, 263 Caucasian, 10 other) were evaluated. Before donation, AA had higher serum creatinine concentrations, estimated glomerular filtration rate (GFR) values, and SBP levels than Caucasians. No significant changes in SBP or renal function were observed between the two groups within the first year after donation, although results were limited by incomplete follow‐up. Conclusion: AA had higher pre‐donation serum creatinine, GFR, and SBP values compared to Caucasians; however, the degree of change in renal function and blood pressure did not differ between groups following kidney donation. Although long‐term studies are needed, our study suggests that AA and Caucasians experience similar short‐term consequences after donation. The incomplete data available on donor outcomes in our center and in prior publications also indicates a global need to implement systems for structured follow‐up of live kidney donors.
