Serum levels of soluble receptor for advanced glycation endproducts (sRAGE) are higher in ulcerative colitis and correlate with disease activity
Bibliographic record
Abstract
UNLABELLED: Interaction of the receptor for advanced glycation endproducts (RAGE) with its ligands results in expression of inflammatory mediators, activation of NF-κB, and induction of oxidative stress, all of which have been implicated in the pathogenesis of inflammatory bowel diseases (IBD). Soluble receptor for advanced glycation endproducts (sRAGE) has recently emerged as a reliable biomarker of inflammation in numerous RAGE-mediated disorders. OBJECTIVE: To assess sRAGE levels in adult patients with IBD. METHOD: Serum was collected from adult patients with Crohn's disease (CD, 56 patients), ulcerative colitis (UC, 60 patients), and healthy controls (HC, 113 subjects). Levels of sRAGE were determined by enzyme-linked immunosorbent assay. RESULTS: Serum sRAGE levels were elevated in IBD compared to HC and were higher in UC patients compared to CD and HC. Levels of sRAGE were significantly higher in the serum of UC patients with active disease compared to patients with inactive disease, but no association with the Montreal Classification was evident. Serum sRAGE was lower in CD patients with biological therapies. CONCLUSIONS: These findings suggest that serum levels of sRAGE are altered in patients with intestinal inflammation and may reflect distinct immunoinflammatory pathogenesis of UC and CD.

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.
