[Daclizumab in combination with mycophenolate mofetil and a late introduction of Tacrolimus at low doses, as a therapeutic approach in the elderly renal transplant donor-recipients pairs in kidney transplant].
BACKGROUND
Nowadays, it is more frequent the use of kidneys from older donors in the renal transplantation. Moreover, it is also increasing the age of the recipients due to the ageing of the population treated with hemodialysis. This makes that recipients become older more commonly. This situation raises specific problems in the renal graft and in the recipient as well. In this manuscript we present the results of a multicenter study that analyzed an immunosuppressive strategy specifically designed to elderly renal transplant donor-recipients.


METHODS
Patients > or =50 years were transplanted from donors > or =55 years. Immunosuppressive strategy consisted of daclizumab (2 doses of 1mg/Kg) in combination with steroids, mycophenolate mofetil (2g/daily during the first 45 days and then adjusted according to local practice) and Tacrolimus. Tacrolimus was introduced between 5 and 7 day post-transplantation, adjusting the predose levels between 4-8 ng/mL. Mean follow-up was 12 months.


RESULTS
A total of 133 patients were included in the study. Mean age of recipients and donors was 61.3+/-6.2 years and 64.4+/-5.3, respectively. 42.9% of patients needed dialysis during the first week (median 4 days). Between first month and first year, serum creatinine improved from 2.0+/-1.0 mg/dl to 1.5+/-0.4 mg/dl. Similar improvements were observed when creatinine clearance (Cockroft-Gault) was calculated. The survival of patient and renal graft at 12 months was 97.7% and 96.1%, respectively. The acute rejection rate was 13.5%. Security profile was good, as expected.


CONCLUSIONS
The Daclizumab and mycophenolate mofetil regimen with a late introduction of Tacrolimus at low doses is a good alternative in the elderly renal transplant recipients with a low immunologic risk.
