Impact of the addition of maintenance steroids to a rapid steroid discontinuation immunosuppressive protocol following acute renal transplant rejection.

OBJECTIVES

Rapid steroid discontinuation immunosuppressive protocols are increasingly used in renal transplant. The optimal immunosuppressive regimen in patients who develop acute rejection while on a rapid steroid discontinuation protocol is less clear. We examined our experience of adding maintenance steroid therapy in renal transplant recipients who developed 1 or more acute rejection episode while on a rapid steroid discontinuation protocol.

MATERIALS AND METHODS

The outcome of 145 patients who underwent renal transplant from 2002 to 2007 and initiated a rapid steroid discontinuation protocol was analyzed. Patients were divided into the following 5 groups: (i): acute rejection X 1 and no maintenance steroids, (ii): acute rejection X 1 and started on maintenance steroids, (iii): acute rejection X 2 and no maintenance steroids (iv): acute rejection X 2 and started on maintenance steroids, and (v): no acute rejection

RESULTS

Compared with patients with no acute rejection, graft survival was significantly inferior in patients who experienced 2 or more acute rejection episodes-whether they were started on maintenance steroids (P = .003) or not (P = .006) - but was similar in patients who experienced only 1 episode of acute rejection, and were started either on maintenance steroids (P = .87) or were continued on the rapid steroid discontinuation protocol (P = .69). In patients who sustained 2 episodes of acute rejection, addition of maintenance steroids had no impact on graft survival (P = .97).

CONCLUSIONS

More than 1 episode of acute rejection in renal transplant recipients on rapid steroid discontinuation protocol is associated with poor, long-term, graft survival, which remains unchanged despite starting maintenance steroids. The use of maintenance steroids may not have a positive impact on graft survival after acute rejection.
