We hypothesized that predictors of outcome in live donor transplants were likely to differ significantly from deceased donor transplants, in which cold ischaemia time, cause of donor death and other donor factors are the most important predictors. The primary aim was to explore the independent predictors of graft function in recipients of live donor kidneys (LDK). Our secondary aim was to determine which donor characteristics are the most useful predictors. A retrospective analysis was undertaken of all patients receiving live donor (n = 206) renal transplants at our institution between 31 May 1994 and 15 October 2002. Twelve patients were excluded from the analysis. Follow-up was completed on all patients until graft loss, death or 22 November 2003. We explored predictors of Nankivell glomerular filtration rate (GFR) at 6 months by multivariate linear regression. In the 194 patients studied, the mean recipient 6-month Nankivell GFR was 59 +/- 15 ml/min/1.73 m(2). Independent predictors of recipient GFR in at 6 months were donor Cockcroft-Gault GFR (CrCl; beta 0.16; CI 0.13 to 0.29; P < 0.0001), steroid resistant rejection (beta-6.07; CI -12.05 to -0.09; P = 0.006) and delayed graft function (DGF) (beta-10.0; CI -19.52 to -0.49; P = 0.039). Renal function in an LDK transplant recipients is predicted by donor GFR, episodes of steroid resistant rejection and DGF. Importantly, donor Cockcroft-Gault GFR is the most important characteristic for predicting the recipient renal function.
