In January 2007, our centre changed from a cyclosporine (CyA)/azathioprine (Aza)/ prednisolone (Pred) primary immunosuppression regimen (with basiliximab induction and mycophenolate mofetil [MMF] for those at immunologically high risk) to a tacrolimus (Tac) (low dose)/MMF/Pred regimen with basiliximab induction, following presentation of Symphony trial results. This analysis assesses the impact of this change on 5-year outcomes. Three hundred consecutive renal-only transplants were identified: 140 from the 2005-06 era and 160 from the 2007-08 era. The proportions of living donor (37.5 vs. 22.9%; p = 0.04) and donors after circulatory death (11.9 vs. 5.0%; p = 0.03) were higher in the 2007-08 cohort. Five-year actuarial patient survival was higher in the 2007-08 cohort (96.8 vs. 87.1%; p = 0.003), with a trend toward higher 5-year transplant survival (84.7 vs. 76.3%; p = 0.08). Estimated glomerular filtration rate (eGFR) was higher than in the 2005-06 era at 1 (53.5 vs. 44.5 ml/min/1.73m2; p = 0.0006) and 3 years (50.9 vs. 43.4 ml/min/1.73m2; p = 0.02), with a trend toward higher eGFR at 5 years (41.8 vs. 49.6 ml/min/1.73m2; p = 0.09). Differences were consistent when living donor and deceased donor transplants were analysed separately. In a \real world\" population
