Peritoneal Dialysis in Orthotopic Liver Transplantation Recipients.

Abstract

In many dialysis programs, there is resistance to initiating peritoneal dialysis (PD) in liver transplant patients needing renal replacement therapy. This retrospective study reviews the outcome of PD in liver transplant patients at a major transplantation and dialysis center. We performed a retrospective cohort study in patients who underwent liver transplants and received PD between 1991 and 2016. Patient demographics, laboratory parameters, and adverse events were collected from our electronic database. Between 1991 and 2016, 14 patients underwent liver transplants and subsequently received PD. The mean age was 59.0 ± 7.1 years; 42.8% women; the mean time from transplant to PD initiation was 9.7 ± 2.8 years; average follow-up on PD was 31.3 months (range: 9 - 87 months). Hepatitis C was the main cause of liver failure necessitating the transplant (8 patients). Calcineurin inhibitor toxicity was the lead cause of end-stage renal disease (ESRD) (12 patients). The overall peritonitis rate was 39.8 patient-months (0.3 episodes per year at risk). There was 1 patient with relapsing peritonitis, and 1 patient had severe peritonitis and died. Mean survival was 58.9 ± 11.3 months, 4 patients died, 4 received a kidney transplant, 1 patient was transitioned to hemodialysis due to poor ultrafiltration, 1 patient was transferred to another program, 2 remained on PD and 2 patients recovered renal function. Eight patients underwent liver biopsies during their time on PD without complication. There appears to be no specific concern related to liver transplant patients undergoing PD. Peritonitis and mortality rates were no different from other solid organ recipients or even from the general PD population. The hepatic graft was never threatened, even during peritonitis. Therefore, these patients should not be denied the option of PD.
