[Early steroid withdrawal after kidney transplantation].

Background: The side effects of steroid are serious problems in renal transplant patients. However, withdrawal of steroid has been controversial. We evaluated the benefits and risk of early steroid withdrawal after renal transplantation.

Patients And Methods: The outcomes of early steroid withdrawal from triple immunosuppressive drug therapy were analyzed in four living related and one cadaveric renal transplant recipients. The dosage of steroid was gradually reduced and the time of steroid withdrawal after transplantation was 5 to 7.5 months.

Results: Four Patients have been able to be free from steroid and maintained stable graft functions and normal urinary findings for 14 to 33 months after withdrawal. The findings of rejection were not observed in the graft specimens obtained by serial biopsies. One patient who received a living related graft developed an increase in serum creatinine level and proteinuria two weeks after discontinuation of steroid. The serum creatinine level returned to that before withdrawal and proteinuria disappeared by steroid readministration. Long term side effects of steroid were not observed in 4 patients with successful steroid withdrawal.

Conclusion: These results suggest that steroid withdrawal about 6 months after transplantation can be accomplished without jeopardizing graft function in selected renal transplant recipient and the withdrawal in the early stage is preferred for reducing the side effects. Careful and long-term follow up are required to assess the further risk and benefit of steroid withdrawal on immunosuppressive morbidity.
