Natural history of cadaveric kidney transplants in the absence of early acute rejection.

Overview

The foremost goal in organ transplantation is to achieve normal graft function without rejection. 31 (8.7%) of 357 cadaveric kidney transplant had no evidence of rejection for the first 3 months. Among these, 2 patients died with a functioning graft and four grafts failed during the 1- to 7-year follow-up period. Actuarial graft survival rates of these patients were 96.8 and 79.0% at 2 and 5 years, respectively, as compared with 64.6 and 51.2%, respectively, for the controls (p less than 0.01). Multiple preoperative blood transfusions and the adjunctive immunosuppressive therapy with retroplacental gamma globulin appeared to be playing a role for the induction of the 'no-rejection' state. However, continuous immunosuppressive therapy is necessary to maintain graft function.
