Immunosuppression in the failing and failed transplant kidney: optimizing outcomes.

There is little data to guide clinicians on the optimal management of immunosuppression in patients whose kidney transplant has failed and who have returned to dialysis. Nor is there robust data on whether to perform a transplant nephrectomy. Finally, management of late stage chronic kidney disease, including deciding on dialysis initiation, modality and access planning, must occur simultaneously with efforts aimed at preserving the failing kidney and residual renal function for as long as possible. In this article, we will review the evidence on these topics and suggest areas for improvement.
