Effects of satavaptan, a selective vasopressin V2 receptor antagonist, on ascites and serum sodium in cirrhosis with hyponatremia
Bibliographic record
Abstract
UNLABELLED: Hyponatremia in cirrhosis is associated with significant morbidity and mortality and complicates ascites management. Vasopressin receptor antagonists improve serum sodium concentration by increasing renal solute-free water excretion, but their effects on the management of ascites have not been assessed. Our aim was to investigate the effects of satavaptan, a highly selective vasopressin V(2) receptor antagonist, on ascites management and serum sodium in hyponatremic patients with cirrhosis. A total of 110 patients with cirrhosis, ascites, and hyponatremia (serum sodium < or =130 mmol/L) were included in a multicenter, double-blind, randomized, controlled study comparing three fixed doses of satavaptan (5 mg, 12.5 mg, or 25 mg once daily) versus placebo. Duration of treatment was 14 days and all patients received spironolactone at 100 mg/day. Satavaptan treatment was associated with improved control of ascites, as indicated by a reduction in body weight (mean change at Day 14 was +0.49 kg [+/-4.99] for placebo versus +0.15 kg [+/-4.23], -1.59 kg [+/-4.60] and -1.68 kg [+/-4.98] for the 5 mg, 12.5 mg, and 25 mg doses, respectively; P = 0.05 for a dose-effect relationship overall) and a parallel reduction in abdominal girth. This beneficial effect on ascites was associated with improvements in serum sodium (mean change from baseline to day 5 was 1.3 +/- 4.2, 4.5 +/- 3.5, 4.5 +/- 4.8, and 6.6 +/- 4.3 mmol/L for the placebo group and the groups on satavaptan at 5 mg, 12.5 mg, and 25 mg/day, respectively; P < 0.01 for all compared to placebo). Thirst was significantly more common in patients treated with satavaptan compared to those treated with placebo, whereas the frequency of other adverse events was similar among groups. CONCLUSION: The V(2) receptor antagonist satavaptan improves the control of ascites and increases serum sodium in patients with cirrhosis, ascites, and hyponatremia under diuretic treatment.

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.
