Abstract

Background: The efficacy of terlipressin in improving pre-liver transplant renal function in hepatorenal syndrome (HRS) has been well documented, however, its impact on post-transplant renal function remains poorly described. This study aims to describe the impact of HRS and terlipressin on post-liver transplant renal function and survival.

Methods: A single-centre, retrospective, observational study was conducted to identify post-transplant outcomes of patients diagnosed with HRS undergoing liver transplant (HRS cohort) and those undergoing transplant for non-HRS, non-hepatocellular carcinoma cirrhotic indications (comparator cohort) between January 1997 and March 2020. The primary outcome was serum creatinine at 180 days post-liver transplant. Other renal outcomes and overall survival were secondary outcomes.

Results: 109 patients with HRS and 502 comparator patients underwent liver transplant. The comparator cohort was younger than the HRS cohort (53 vs. 57 years, P < 0.001). The median creatinine at day 180 post-transplant was higher in the HRS transplant group (119 µmol/L vs. 103 µmol/L, P < 0.001), however, this association lost significance following multivariate analysis. Seven patients (7%) in the HRS cohort received a combined liver-kidney transplant. There was no significant difference in the 12-month post-transplant survival between the two groups (94% vs. 94%, P = 0.5).

Conclusion: Patients with HRS treated with terlipressin who subsequently undergo liver transplantation have post-transplant renal and survival outcomes comparable to patients transplanted for cirrhosis without HRS. This study supports the practice of liver-only transplant in this cohort and the reservation of renal allografts for those who have primary renal disease.
