title: A comparison of prednisolone and methylprednisolone for renal transplantation.
abstract: A large difference in immunosuppressive potency between methylprednisolone and prednisolone has been suggested in vitro. However, the selection of the best glucocorticoid for renal transplantation has been seldom considered so far. Thus, the present study was undertaken to compare therapeutic efficacy between prednisolone and methylprednisolone in renal transplantation. We studied 42 renal transplant recipients who were operated on between 1990 and 1994. The patients were divided into two treatment groups: a methylprednisolone/ cyclosporine group (n = 19) and a prednisolone/cyclosporine group (n = 23). Clinical outcome and drug side effects were compared retrospectively between the treatment groups 24-84 months after transplantation. The overall graft survival time in patients treated with methylprednisolone/cyclosporine was superior to that in patients treated with prednisolone/cyclosporine (p < 0.05). Among the recipients from cadaver donors, 5/16 (31.3%) treated with prednisolone required nephrectomy, whereas none of the 10 patients treated with methylprednisolone received nephrectomy (p < 0.01). An examination of the recipients from living related donors revealed that serum creatinine levels 24-36 months after operation were significantly lower in the methylprednisolone group (p < 0.05). Cyclosporine trough levels and glucocorticoid side effects were similar between the treatment groups. The results raised the possibility that methylprednisolone is superior to prednisolone when combined with cyclosporine for maintenance immunosuppressive therapy in renal transplantation.
