11-year experience of kidney retransplantation in elderly recipients in Sklifosovsky Research Institute for Emergency Medicine

Introduction. In spite of improvements in quality of life and lifetime of kidney transplant recipients the limited time of kidney transplant survival dictate the need for returning back to dialysis or repeat kidney transplantation. In respect that the need of repeat kidney transplantation usually observed in elderly recipients we attach importance in the analysis of outcomes of kidney retransplantation in patients over 60-s.

Aim: to analyse the early outcomes of kidney re-transplantations in middle-aged and elderly recipients.

Material and methods: the retrospective analysis of outcomes of 124 repeat kidney transplantations was made (16 transplantations in elderly recipients -Group I; 108 transplantations in recipients aged 20-59 yrs - Group II). The recovery of kidney transplants, acute rejection rates, the causes and the rate of kidney transplant dysfunction and failure, early patient’s and kidney transplant’ survival rates were analyzed. We used clinical, laboratory, histological and instrumental diagnostics.

Results: in both groups there were no differences in kidney transplant recovery rates (p = 0,546), kidney transplant function (normal function 81,2% vs 86,1%, dysfunction 6,3% vs 4,3%, graft failure 12,5% vs 9,3% (p = 0,876), recipient 100% vs 99,1% (p = 0,34) and graft survival rates 87,5% vs 90,7% (p = 0,30). There were no episodes of acute rejection in patients of group I (0% vs 30,6% (p = 0,006). The reason of graft failure in group I - the graft’s pathology (nephroangiosclerosis (12,5%), group II - intractable acute rejection (4,6%), graft’s pathology (3,7%), patient’s death with functioning graft (0,9%).

Conclusion: there were similar recipient and graft survival rates in both groups. We observed lower acute rejection rate in patients of group I using sufficient immunosuppressive regimens.
