Background: Studies using tacrolimus and corticosteroids or the combination of cyclosporine, mycophenolate mofetil, and corticosteroids have been shown to reduce the incidence of biopsy-proven acute rejection episodes in cadaveric kidney recipients compared with cyclosporine-based immunosuppression. The current study is a retrospective analysis of our experience with tacrolimus combined with mycophenolate mofetil and steroids as primary immunosuppression for kidney transplant recipients.
Methods: In a retrospective analysis, 72 patients who received primary therapy with tacrolimus, mycophenolate mofetil, and corticosteroids (triple therapy) were compared with a control group of 98 kidney recipients who received tacrolimus and corticosteroids (double therapy).
Results: There was a significant reduction in the incidence of biopsy-confirmed acute rejection in the triple therapy group (8.2%) compared with the double therapy group (21%; P=0.003). One-year patient and graft survival did not differ between groups. The incidence of posttransplant diabetes mellitus was 18% and 21% in the triple and double therapy groups, respectively. Leukopenia and gastrointestinal side effects were the most common cause for discontinuation of mycophenolate mofetil.
Conclusions: The combination of tacrolimus with mycophenolate mofetil and corticosteroids is more effective at preventing early acute rejection than tacrolimus and corticosteroids alone. The use of mycophenolate mofetil was associated with a higher incidence of leukopenia and diarrhea, often leading to discontinuation of the drug.
