Prospective randomised trial of the use of Daclizumab in renal transplantation using kidneys from non heart beating donors

Transplantation using non-heart beating donors (NHBD) is one way of reducing the global kidney shortage. Unfortunately the large warm ischaemic insult sustained by the graft leads to a high rate of delayed graft function (DGF). We have investigated the use of a regimen utilising an II-2r blocker (DZB) in place of Tacrolimus for the initial post-operative immunosupression with the aim of reducing the incidence of DGF.Prospective randomised controlled trial based in two NHBD UK centres (Leicester and Newcastle). 51 patients were enrolled over two years and randomised into two treatment arms: 1. DZB/MMF/Steroids (Tacrolimus started when creatinine dropped below 350 micromol/l) 2. Tacro/MMF/Steroids.There was one death, during the study period, in a patient who had had a non-functioning graft removed. The overall incidence of immediate function (IF) was higher than expected (28%), no significant difference was found in the incidence of immediate graft function between the two groups (35% group 1 and 22% group 2). Sub-group analysis however has shown a significant advantage for the delayed introduction of Tacrolimus for machine perfused grafts (IF: 53% vs 13%, chi2 p=0.015). There was no difference in the rate of rejection.The delayed introduction of Tacrolimus reduces the incidence of DGF in machine-perfused NHBD kidney transplantation.
