Five-year results of kidney transplantation under tacrolimus-based regimes: the persisting significance of vascular rejection

Transplantation. 2003 Oct 15;76(7):1120-3. doi: 10.1097/01.TP.0000076474.76480.A4.

Abstract

Background: Acute rejection has been the major risk factor for medium-term kidney graft loss because of chronic allograft nephropathy. We investigated whether the use of improved immunosuppression has altered the relationship between acute and chronic rejection by analyzing data from 245 renal transplant patients receiving Tacrolimus-based immunosuppression.

Results: Five-year graft survival (censored for death with functioning graft) was 88.8% with no significant difference between living and cadaveric kidney transplants. The only significant predictor of medium-term graft loss was acute vascular rejection.

Conclusion: Under Tacrolimus-based immunosuppression, the occurrence of acute interstitial rejection, even when occurring late, repeatedly, or with failure of graft function to return to baseline, was not associated with chronic allograft nephropathy or medium-term graft loss. Vascular rejection remains the major immunological obstacle to long-term transplant success. Five-year overall survival rates with a functioning graft of 80% with 90% graft survival censored for death with function seem to be realistic and achievable goals.
