The investigators analyze the clinical outcome of steroid withdrawal protocol starting at 3 months after kidney transplantation using tacrolimus, Mycophenolate Mofetil (MMF), and basiliximab. This study is an open-label, prospective, controlled clinical trial in a single center. Those patients who fulfill the entry criteria could enter in this prospective controlled trial of steroid withdrawal three months after transplantation.

Primary Outcome Measures:
  • the incidence of biopsy-confirmed acute rejection. [ Time Frame: 12 months ]
    The primary efficacy variable was the incidence of biopsy-confirmed acute rejection.

Secondary Outcome Measures:
  • death, graft loss [ Time Frame: 12 months ]
    The secondary efficacy variables included the cumulative incidence of a composite endpoint of death, and graft loss;

  • adverse events and serious adverse events [ Time Frame: 6 months , 12 months ]
    The proportion of successfully steroid-withdrawn and steroid-free population at 6 months and at 12 months post-transplantation as well as the safety variables including the incidence of adverse events and serious adverse events, [blood pressure, lipid levels (total cholesterol), BUN (blood urea nitrogen) and blood glucose levels]

Estimated Enrollment: 30
Study Start Date: May 2008
Estimated Study Completion Date: July 2012
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: steroid withdrawal
The clinical outcome after kidney transplantation, under the immunosuppression of steroid withdrawal starting at 3 months post-transplantation using tacrolimus, mycophenolate mofetil, and basilixumab should be analyzed.
Drug: Prednisolone
Those patients who fulfill the entry criteria enter in this prospective controlled trial of steroid withdrawal starting at three months after transplantation

Detailed Description:

Those patients who fulfill the entry criteria enter in this prospective controlled trial of steroid withdrawal starting at three months after transplantation. The entry criteria include 1) no episode of clinically treated nor biopsy confirmed acute rejection up to entry; 2) serum creatinine level equal to or less than 2 mg/mL on three separate measurements; 3) no proteinuria (urine protein less than 1000 mg/24 hours; 4) tacrolimus trough level > 5 ng/ml without signs of nephrotoxicity; 5) agreement to follow the study protocol.

For the patients who enter into the protocol, prednisolone would be slowly withdrawn by 2.5 mg in every two weeks until 8 weeks after entering the protocol (5 months post-transplantation). The patients visit every week, and they are closely monitored with symptoms and signs, blood cell count, chemistry, and urinalysis.
