The goals and outcomes of immunosuppression in renal transplantation have changed significantly over the last 30 years. When graft survival rates were relatively low and acute rejection was a frequent occurrence in the early era of transplantation, the goal of immunosuppression was to improve survival and reduce the rate of acute rejection. Today, with excellent graft survival rates and a low incidence of acute rejection, the goal of immunosuppression has shifted toward not only eliminating acute rejection, but also toward reducing the side effects of medications, and maintaining long-term graft function by decreasing chronic nephropathy. Between September 1982-December 2004, 3,211 primary kidney transplant procedures were performed at The Ohio State University. We excluded from analysis all combined transplants as well as patients who were involved in clinical research protocols. Our immunosuppressive protocol changed substantially over this 24-year period, which can be divided into 5 eras in time. Each era is defined by a distinct immunosuppressive protocol that resulted in an incremental improvement in outcomes of patient and graft survival rates. In the present study, the outcomes of each era in patients with previous kidney transplant only are compared and future directions are discussed. The incidence of acute rejection episodes and graft survival from each era are compared and demonstrate the substantial improvement in results that have been achieved over the past 24 years.
