RESUMO
BACKGROUND AND AIMS: Hepatorenal syndrome-acute kidney injury (HRS-AKI) is associated with significant morbidity and mortality. While liver transplantation is the definitive treatment, continuous terlipressin infusion for HRS-AKI may provide benefit and as such was assessed in a population comprised of liver transplant (LT) candidates. METHODS AND RESULTS: Fifty hospitalized, LT-eligible patients with HRS-AKI received a single bolus followed by continuous terlipressin infusion. ACLF grade 3, serum creatinine (SCr)>5.0 mg/dL, or MELD≥35 were exclusions. Fifty hospitalized patients who received midodrine and octreotide (M&O) or norepinephrine (NorEpi) for HRS-AKI served as a historical comparator cohort. Complete response (CR) was defined as ≥30% decrease in SCr with EOT SCr≤1.5, partial response (PR) as ≥30% decrease in SCr with EOT SCr>1.5, and non-response (NR) as <30% decrease in SCr. CR rate was significantly higher in the terlipressin cohort compared to the historical cohort (64% vs. 16%, p<0.001). Survival, while numerically higher in those who received terlipressin, was statistically similar (D30: 94% vs. 82%, p=0.12; D90: 78% vs. 68%, p=0.37). Renal replacement therapy (RRT) was more common among terlipressin NR than CR and PR (70% vs. 3% vs. 13%, p<0.001). EOT MELD and SCr were significantly lower within terlipressin cohort (MELD: 19 vs. 25, SCr: 1.4 vs. 2.1 mg/dL, p<0.001). Sixteen of 40 terlipressin-treated patients received LT-alone (terlipressin CR in 10/16). One patient on terlipressin had hypoxic respiratory failure that responded to diuretics; one possibly had drug-related rash. CONCLUSIONS: With continuous terlipressin infusion, a CR rate of 64% was observed with a favorable safety profile. Terlipressin use was associated with lower EOT MELD and SCr than the historical M&O/NorEpi cohort; LT-alone was accomplished in a high proportion of complete terlipressin responders.
