Incidence of leukopenia and cytomegalovirus disease in kidney transplants treated with mycophenolate mofetil combined with low cyclosporine and steroid doses.

Abstract：

:Mycophenolate mofetil (MMF) combined with conventional cyclosporine and steroids doses efficiently prevents acute rejection in kidney transplants. However, this regimen has been associated with an increased incidence of cytomegalovirus (CMV) disease and leukopenia, specially in patients receiving MMF at 3 g/d, suggesting that the combination of two powerful immunosuppressants carries the risk of overimmunosuppression. For this reason, we treated a group of patients with MMF 3 g/d combined with low cyclosporine and steroids doses. Eighty-two kidney transplants performed at two centers and enrolled in the European Mycophenolate Mofetil Cooperative Study were randomized to receive: A) placebo (n = 27); B) MMF 2 g/d (n = 27); and C) MMF 3 g/d (n = 28). In this double blind study all patients received cyclosporine and steroids at conventional doses. Fifteen kidney transplants enrolled in an MMF open pharmacokinetic study were treated with MMF 3 g/day combined with low cyclosporine and steroid doses (group D). Efficacy was evaluated as the incidence of biopsy proven acute rejection, and safety focused on CMV disease and leukopenia. Patients receiving MMF showed a low incidence of biopsy proven rejection (B) 18.5%; C) 10.7%; and D) 13.3%). Patients of group C had a high incidence of CMV disease (35.7%) when compared with the other groups (lower than 8%). Incidence of leukopenia was higher in patients treated with MMF (B) 25.9%; C) 39.3%; and D) 40%) than in placebo treated patients (7.4%). Patients in group (C) displayed leukopenia mainly in the context of CMV disease, while patients of group (D) had leukopenia not related to CMV infection. All patients of group (D) who presented leukopenia recovered after MMF reduction dose, while in group (C) there were 5 out of 28 patients who required MMF withdrawal. We propose that a reasonable approach to take advantage of a powerful non-nephrotoxic immunosuppressant such as MMF, could be the administration of this drug at 3 g/d from the time of transplantation combined with low CsA and steroid doses.
