Renal Transplantation
Conditions
Brief summary
Part 1 of the study is to gradually withdraw steroids in a group of 50 older renal transplant recipients, converting then from the 3 drug regimen to a 2 drug regimen (cyclosporine and MMF), while carefully monitoring their graft function. 25 subjects would serve as control patients in the study and would remain on the 3 drug regimen (steroids, cyclosporine and MMF). Immunologic status will be determined before and after IS withdrawal using a delayed-type hypersensitivity (DTH) transfer test previously described in the original submission. Both the steroid withdrawal subjects and the control subjects will undergo the DTH testing throughout the 3 years of study participation.
Interventions
prednisone withdrawal, with maintenance mycophenolate mofetil therapy and either cyclosporine or tacrolimus

Eligibility
Inclusion criteria
* Patient who have received a kidney transplant during the MMF era * Patients who have stable graft function indicated by a serum creatinine of \< 1.8 mg/dl, or a calculated creatinine clearance of \> 50 ml/minute
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence of Allograft rejection | 3 years |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Renal function as determined by serum creatinine | measure after 36 months | — |
| Allograft Survival | 3 years | — |
| Immunological function as determined by Trans-vivo delayed hypersensitivity assay (TV-DTH) | Day 0 (pre-transplant) | Research assay done to determine correlation between the status of donor specific regulation (DSR) and rates of rejection in both arms of the study. |
