For patients who meet the inclusion criteria and who agree to participate in this study, the investigators sampled peripheral blood 10cc and performed the analysis for immunologic profile just before the conversion of immune suppressant. At 1 month, 6 month, and 1 year from the conversion of Immune suppressant (CNI to rapamune), the investigators performed tha analysis fo immune profile again. During the study period, the interval of the visit of subclinic and the kinds of laboratory test (Blood and urine test) would not change compared to before the start of this study.

    Number of episode of biopsy proven acute rejection

Secondary Outcome Measures:
  • Serum Creatinine, MDRD eGFR [ Time Frame: Study duration is 12 months ]
    Mean diurnal Serum Creatinine, MDRD eGFR change of greater than or equal to 20% at month 12 vs baseline

Estimated Enrollment: 50
Study Start Date: May 2012
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Sirolimus
    Beginning on day, an initial maintenance dose of 2mg/day should be given. A trough level should be obtained between days 3 and 8, and the daily dose of sirolimus should be adjusted thereafter.
