The effect of 1 month of therapy with midodrine, octreotide‐LAR and albumin in refractory ascites: a pilot study
Bibliographic record
Abstract
BACKGROUND: The pathogenesis of refractory ascites (RA) is linked to splanchnic vasodilation. We hypothesized that a combination of midodrine, octreotide long-acting release (LAR) and albumin would result in increased natriuresis, better control of ascites and an improvement in renal function in patients with RA+/-Type 2 hepatorenal syndrome. METHODS: A prospective pilot study in patients with RA as defined by the International Ascites Club. Consecutive patients received an intramuscular injection of octreotide-LAR, 50 g of albumin three times per week and midodrine titrated to increase the systolic blood pressure for 1 month. RESULTS: Ten patients with RA were enrolled and eight with complete data to 1 month post-treatment were included in the analysis. There was no change in renal function but there was a trend towards a reduction in the volume of ascites removed by paracentesis (P=0.08) and a significant reduction in the plasma renin (P=0.01) and aldosterone concentrations (P=0.01). Interestingly, there was a transient worsening in the model for end-stage liver disease (MELD) score (P=0.01). The deterioration in MELD was completely reversible after discontinuation of therapy. CONCLUSIONS: To our knowledge, this is the first study of prolonged midodrine, octreotide and albumin therapy in RA. We observed a significant reduction in the plasma renin and aldosterone concentrations and a trend towards a reduction in the volume of ascites removed by paracentesis without an effect on renal function. The beneficial effects are at the expense of a reversible deterioration in the MELD score. Large controlled trials are needed before this therapy can be routinely recommended.

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.
