Serum Albumin Is Inversely Associated With Portal Vein Thrombosis in Cirrhosis
Bibliographic record
Abstract
We analyzed whether serum albumin is independently associated with portal vein thrombosis (PVT) in liver cirrhosis (LC) and if a biologic plausibility exists. This study was divided into three parts. In part 1 (retrospective analysis), 753 consecutive patients with LC with ultrasound‐detected PVT were retrospectively analyzed. In part 2, 112 patients with LC and 56 matched controls were entered in the cross‐sectional study. In part 3, 5 patients with cirrhosis were entered in the in vivo study and 4 healthy subjects (HSs) were entered in the in vitro study to explore if albumin may affect platelet activation by modulating oxidative stress. In the 753 patients with LC, the prevalence of PVT was 16.7%; logistic analysis showed that only age (odds ratio [OR], 1.024; P = 0.012) and serum albumin (OR, −0.422; P = 0.0001) significantly predicted patients with PVT. Analyzing the 112 patients with LC and controls, soluble clusters of differentiation (CD)40‐ligand ( P = 0.0238), soluble Nox2‐derived peptide (sNox2‐dp; P < 0.0001), and urinary excretion of isoprostanes ( P = 0.0078) were higher in patients with LC. In LC, albumin was correlated with sCD40L (Spearman’s rank correlation coefficient [ rs ], −0.33; P < 0.001), sNox2‐dp ( rs , −0.57; P < 0.0001), and urinary excretion of isoprostanes ( rs, −0.48; P < 0.0001) levels. The in vivo study showed a progressive decrease in platelet aggregation, sNox2‐dp, and urinary 8‐iso prostaglandin F2α‐III formation 2 hours and 3 days after albumin infusion. Finally, platelet aggregation, sNox2‐dp, and isoprostane formation significantly decreased in platelets from HSs incubated with scalar concentrations of albumin. Conclusion: Low serum albumin in LC is associated with PVT, suggesting that albumin could be a modulator of the hemostatic system through interference with mechanisms regulating platelet activation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
