Summary

The objective of this study is to examine the effect on allograft function and histology of converting African American renal transplant recipients with chronic allograft nephropathy (CAN) from a tacrolimus-based regimen to a sirolimus-based maintenance immunosuppression regimen.

The investigators hypothesize that the conversion from tacrolimus to sirolimus in African American renal recipients will stabilize or improve renal allograft function, and stabilize the histological progression of CAN. This conversion will have the potential to prolong long-term graft survival in African American renal transplant patients.

GFR measurements, histological parameters on the allograft biopsy, as well as patient and graft survival, incidence of acute rejection, and specific side effects will be monitored and compared between the sirolimus conversion group and the patients who will be maintained on tacrolimus.

Conditions

  • Glomerular Filtration Rate
  • Chronic Allograft Nephropathy

Interventions

DRUG

sirolimus

The subjects assigned to the sirolimus conversion group will be initiated on sirolimus 5mg po daily at which time their tacrolimus dose will be decreased by 50%. Sirolimus levels will be checked within a week and adjusted in a linear fashion to achieve a trough goal of 12-15ng/ml in subjects within 1 year post-transplant, and 8-12 ng/ml in subjects more than 1 year post-transplant. Tacrolimus will be continued in these subjects until sirolimus target trough levels are achieved. Thereafter, tacrolimus will be discontinued indefinitely. The subjects assigned to the tacrolimus maintenance group (control group) represent our present standard of care.
