Does dialysis modality or duration influence outcomes in simultaneous pancreas-kidney transplant recipients? Single center experience and review of the literature

Abstract

Aim: The influence of dialysis modality and duration on outcomes following simultaneous pancreas-kidney transplantation (SPKT) remains uncertain.

Methods: We performed a single-center retrospective review in 255 SPKT recipients according to dialysis modality (55 preemptive/no dialysis-ND, 70 peritoneal dialysis-PD, 130 hemodialysis-HD) and duration (55 none, 137 < 2 years, 41 2-4 years, 22 > 4 years).

Results: Mean follow-up was 9.4 years (median 9.2 years). Early (3-month) relaparotomy rate (20% ND vs. 36% PD/HD, p = .03) was lower in ND patients. There were no differences in early graft loss, patient survival, overall or death-censored kidney or pancreas graft survival rates (GSR) at 1 or 10 years follow-up. When analyzing dialysis duration, there were no differences in rates of pancreas thrombosis or early pancreas graft loss. Kidney delayed graft function (DGF) was lower in the ND/short dialysis groups combined (1.0%), compared to the intermediate/long dialysis groups combined (9.5%, p = .003). Early relaparotomy rates were higher with longer duration of dialysis (p = .045 between ND and >4 years of dialysis). Patient survival in the long dialysis group was 50% compared to 69.5% in the other three groups combined (p = .09). However, both overall and death-censored kidney and pancreas GSR were comparable.

Conclusions: Preemptively transplanted patients had a lower incidence of kidney DGF and relaparotomy whereas patient survival was slightly lower with longer dialysis vintage prior to SPKT. Dialysis modality and duration did not influence either overall or death-censored pancreas or kidney GSR in patients with short waiting times, low KDPI donor organs, and dialysis duration up to 4 years.
