Efficacy and Safety of Terlipressin Infusion in Hepatorenal Syndrome-Acute Kidney Injury (HRS-AKI): A Retrospective Observational Study
Bibliographic record
Abstract
Background Hepatorenal syndrome-acute kidney injury (HRS-AKI) is an event that occurs in chronic liver disease (CLD) and is associated with high morbidity and mortality. Terlipressin, a vasopressin analog, is used for the treatment of portal hypertension-related gastrointestinal (GI) bleeding and is found to be effective in the management of HRS-AKI. Continuous infusion of terlipressin maintains a high mean arterial pressure while reducing adverse events. It is better tolerated and equally effective at lower doses than intravenous boluses in patients with HRS-AKI. Aim of the study This study aimed to evaluate the safety and efficacy of terlipressin infusion at the rate of 4 mg/day in the treatment of HRS-AKI. Methods This retrospective study included patients who had HRS-AKI according to the modified International Club of Ascites (ICA) definition. Patients were started on a continuous intravenous infusion. The included patients received terlipressin 1 mg stat followed by a 4 mg infusion over 24 hours, and the infusion was continued until specific response criteria were met or for a maximum of seven days. Results In total, 136 patients were included in this study. The mean age of the study group was 45 years, the mean Child-Turcotte-Pugh (CTP) score was 11, the mean model for end-stage liver disease (MELD) score was 30, and the mean serum creatinine was 2.46 mg/dl. A response to treatment in the form of reduction of serum creatinine was observed in 94 (69.1%) patients, 30 (22%) patients showed no response, and worsening of creatinine was seen in 12 (8.8%) patients. The mean duration of hospital stay was 7.6 days, the mean serum creatinine was 1.17 mg/dl at the end of treatment, and the mean CTP and MELD scores in treatment responders were nine and 27, respectively. A total of 29 (21.3%) of 136 patients had adverse events during the terlipressin infusion therapy. Conclusion Terlipressin infusion has sustained effects on splanchnic hemodynamics with fewer and less severe adverse events than intravenous bolus doses. Terlipressin infusion at a dose of 4 mg/day appeared to be well tolerated, with similar outcomes to that of 2 mg/day with a significantly lower albumin dose. These findings emphasize the importance of optimizing treatment protocols, particularly those favoring infusion methods, to enhance efficacy and minimize adverse effects.

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.
