Background
Recipients with a failing kidney transplant (RFKT) receive worse care than those with native disease and outcomes on dialysis after graft loss (DAGL) are poor. Dedicated low clearance transplant clinics (LCTC) are recommended for the management of RFKT but data to support their use is limited. We assessed the management of RFKT at two London transplant centres, one with a dedicated LCTC (Centre A) and one without (Centre B).
Methods
Transplant patients at Bart’s Health (Centre A) and the Royal Free Hospital (Centre B) who transitioned to an alternative form of renal replacement therapy (RRT) between 01/01/2012-30/11/2016 were included. Patients with graft failure within a year of transplantation or due to an unpredictable acute event were excluded. Data were recorded after review of medical records.
Results
179 patients were included; mean age at dialysis restart was 48.6 (+/- 13.4) years, 99 (55.3%) were male, and mean transplant duration was 3678 (+/- 2851) days. Pre-dialysis counseling was documented in 79 (91%) and 68 (74%) patients at Centre A and B respectively (p=0.003). Listing for re-transplantation at restart occurred in 61 (34.1%) patients across both groups. Table 1 outlines clinical parameters at restart and modes of RRT restarted. Outcomes at 1 year after initiation of DAGL were determined in 136 patients; 1-year mortality was 6.6% overall.
Conclusion
A dedicated LCTC improved pre dialysis care. Rates of pre-emptive re-transplantation were low, but 1-year mortality across both centres was better than published estimates.
