Managing the failing renal allograft: navigating a complex topography

Area of Science:

• Nephrology
• Transplantation Medicine
• Immunology

Background:

• Kidney transplant recipients often outlive renal allograft function, necessitating end-stage renal disease (ESRD) management.
• Transitioning from a failing allograft to dialysis presents elevated mortality risks.
• Long-term immunosuppression increases risks of cardiovascular disease, infections, and cancer, impacting patient outcomes.

Purpose of the Study:

• To review the management of kidney transplant recipients with failing allografts.
• To evaluate the benefits and considerations of retransplantation in this patient population.
• To inform clinical decision-making regarding dialysis initiation and immunosuppression management.

Main Methods:

• Literature review and synthesis of current clinical practices.
• Analysis of outcomes associated with different dialysis modalities (hemodialysis vs. peritoneal dialysis).
• Evaluation of retransplantation candidacy and timing.

Main Results:

• Patients with failing transplants often have poorer CKD complication control and higher rates of catheter-based hemodialysis initiation.
• Peritoneal dialysis outcomes are generally comparable to hemodialysis in failing allograft settings.
• Retransplantation can offer a survival benefit, even in older patients, though benefits may diminish after age 70.

Conclusions:

• Proactive assessment for retransplantation before dialysis initiation is vital for optimizing waitlist times and donor identification.
• Management within specialized transplant center clinics focusing on failing allografts may improve outcomes.
• Immunosuppression reduction decisions post-dialysis initiation require careful, patient-centered consideration, particularly regarding retransplantation potential.
