Abstract

Hepatorenal syndrome with acute kidney injury (HRS-AKI), is a unique subset of AKI representing about 11-20% of HRS-AKI episodes in patients with cirrhosis [1,2]. Before the availability of terlipressin in the US in 2022, HRS-AKI therapeutic options had been limited to off-label use of varied vasopressors primarily midodrine with octreotide combination with albumin [3]. Recent studies have shown low mortality (17.6%) and substantial HRS reversal (47.6%) in patients using terlipressin, however <21% patient receive terlipressin as first-line treatment [4,5]. There is sparse evidence in literature assessing real-world treatment patterns and their impact on HRS-related outcomes. Our study aims to fill this gap prior to 2022 and establish a baseline against which future studies of terlipressin can be evaluated in the United States.

DESCRIPTION

Hepatorenal syndrome with acute kidney injury (HRS-AKI), is a unique subset of AKI representing about 11-20% of HRS-AKI episodes in patients with cirrhosis [1,2]. Before the availability of terlipressin in the US in 2022, HRS-AKI therapeutic options had been limited to off-label use of varied vasopressors primarily midodrine with octreotide combination with albumin [3]. Recent studies have shown low mortality (17.6%) and substantial HRS reversal (47.6%) in patients using terlipressin, however <21% patient receive terlipressin as first-line treatment [4,5]. There is sparse evidence in literature assessing real-world treatment patterns and their impact on HRS-related outcomes. Our study aims to fill this gap prior to 2022 and establish a baseline against which future studies of terlipressin can be evaluated in the United States.

We conducted a retrospective, multicenter medical chart review study across 10 medical centers during a 4-year period from January 1, 2016-June 30, 2019 (data were collected until 2021) in the US. The objective was to describe the experience of HRS AKI treatment, with a focus on patient characteristics, treatment patterns, clinical outcomes and healthcare resource use. In this study, we found that prior to the availability of terlipressin, hospitalized HRS-AKI patients experienced poor complete response with off-label treatments (14.6%) and high in-hospital mortality (33.8%). Median (95% CI) overall and transplant-free survival from vasopressor initiation was 48 (32-81) and 28 (19 36) days.

CONCLUSION

Our study uncovered a high disease burden and suboptimal outcomes in HRS patients before terlipressin approval. Study limitations include transcription errors inherent to using medical chart data and focus on practices of physicians from large academic hospitals where more severe patients are likely admitted. HRS-AKI is acute, difficult to diagnose, and practice patterns vary according to local standards of care. Patients referred to such tertiary centers often have a lack of access to early and approved treatments. With the evolving landscape, it is critical to understand the implication of using non-approved regimens and the barriers to access the current standard of care.
