Abstract
BACKGROUND: This study is aimed to determine the impact of living donor (LD) versus deceased donor (DD) kidney transplantation on renal graft survival and patient overall survival rates within Johannesburg, South Africa. MATERIALS AND METHODS: A retrospective assessment was conducted of all 1685 adult first kidney-alone kidney transplant recipients transplanted between the years 1966 and 2013 in a single center. The patients were divided according to the source of the transplant: LD versus DD. Demographics and post-transplantation follow-up data were determined and tabulated. Graft and overall survival plots were generated. RESULTS: Of the recipients enrolled, 84.1% were DD recipients and 15.9% were LD recipients. Living donor recipient status was significantly associated with younger age (p ≤ 0.0001), a higher proportion of white, Asian, or mixed race compared to black race (p ≤ 000.1), a higher proportion of urologic etiology of disease (p = 0.015), and a lower proportion with hypertension (p ≤ 0.0001) as the cause of end stage kidney disease. Results showed a decreased risk of graft failure (hazard ratio, 0.55; 95% confidence interval, 0.45-0.66) and a decreased risk of death (hazard ratio, 0.47; 95% confidence interval, 0.36-0.61) among LD graft recipients as compared to DD graft recipients. CONCLUSIONS: In keeping with internationally reported trends, LD recipients continue to have enhanced patient and graft survival outcomes as compared to DD recipients within our local experience. This Johannesburg experience will serve as a foundation for future related studies in this region of the world.
