title: A prospective study of methylprednisolone and prednisone as immunosuppressive agents in clinical renal transplantation.
abstract: A prospective double blind crossover study was carried out in 65 patients comparing methylprednisolone (Medrol) and prednisone as immunosuppressive agents in clinical renal transplantation to determine their relative merits vis-a-vis graft survival, hypertension, weight gain, sepsis and patient preference in the posttransplant period. Patients receiving renal allografts were randomly assigned to receive initial treatment with one of the drugs. Once maintenance doses were employed, the drug was switched for a 3-month period. There was no difference in overall graft survival at 1 year, 68% versus 56% (p greater than 0.4), for the two patient groups. Likewise, there was no difference in blood pressure during the maintenance therapy crossover period, mean BP 129/86 during Medrol therapy and 129/86 during prednisone therapy. Overall weight gain was not statistically different with the two drugs, 3.8 kg with prednisone and 2.3 kg with Medrol, p greater than 0.1. However, when Medrol was used in the late posttransplant period, the patient had a significantly smaller weight gain, 0.95 kg versus 3.5 kg with prednisone, p greater than 0.05. The incidence of bacterial sepsis was significantly greater (p less than 0.02) during the early posttransplant period in those patients treated with Medrol. Finally, the majority of patients (65%) had no preference for either drug. Of those with a preference, the majority (69%) preferred Medrol. We conclude that therapy with Medrol does not offer superior graft survival, less hypertension or overriding patient preference but does apparently lead to an increased incidence of bacterial sepsis in the early posttransplant period. Thus it appears that prednisone is the initial drug of choice as an immunosuppressive steroid in clinical renal transplantation.
