Current Pharmacologic Therapies for Hepatorenal Syndrome-Acute Kidney Injury
Bibliographic record
Abstract
Background & AimsHepatorenal syndrome (HRS) can occur in patients with cirrhosis and ascites due to splanchnic vasodilation, renal hypoperfusion, and vasoconstriction. HRS is a diagnosis of exclusion and portends a poor prognosis, with upward of 80% mortality at 2 weeks without treatment. This review will highlight randomized controlled trials for HRS pharmacotherapy.MethodsA PubMed review of randomized controlled trials conducted over the past 25 years was undertaken; 18 studies were included.ResultsInitial studies showed that norepinephrine is as effective as terlipressin for HRS reversal. Midodrine with octreotide and albumin is less effective than terlipressin but better than albumin alone at improving 30-day mortality. Recently, terlipressin with albumin led to significantly higher rates of HRS reversal compared to albumin alone. Non-response to terlipressin can predict 90-day mortality in acute-on-chronic-liver failure.ConclusionsOur current understanding of HRS treatment is improved by recent randomized clinical trials. Previous studies using varying medication doses along with the “old” definition of hepatorenal syndrome (HRS type 1) rather than HRS-AKI means that there is still a need for future multicenter prospective studies further refining the risk-benefit ratio of vasoconstrictors for HRS-AKI patients. The Food and Drug Administration has approved terlipressin for use in September 2022. Because it will take time to adapt into clinical practice, less cost-prohibitive vasoconstrictors should still be considered. Opportunities also exist to clarify the safety, timing of initiation, as well as possible discontinuation of terlipressin.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
