Background:
Mycophenolate mofetil (MMF) has been previously shown to prevent functional deterioration in an experimental model of chronic renal allograft rejection.
Methods:
In this retrospective case-control study, patients with chronic rejection who were receiving cyclosporine or tacrolimus and who had MMF added to their immunosuppressive regimen were compared with patients with chronic rejection who were not receiving MMF. Patients were matched for serum creatinine levels and transplant duration at the time MMF was begun.
Results:
In the MMF group, the average dose of MMF was 1482 mg/day with an average duration of 19.3 months. Over 36 months, including 12 months before MMF and up to 24 months on MMF, there was no difference in serum creatinine levels between the two groups. Cyclosporine levels and dose were no different.
Conclusions:
In this small, retrospective, preliminary study, adding MMF to maintenance immunosuppression provided no clear benefit to renal allograft recipients with established chronic rejection. Larger prospective randomized studies are needed.
