Genetic and Serolgical Markers Associated with Pouchitis and a Crohn's Disease-like Phenotype after Pelvic Pouch Surgery for Ulcerative Colitis
Bibliographic record
Abstract
Objective: Study the clinical, genetic and serological factors associated with new onset ileal inflammation in ulcerative colitis (UC) patients who have undergone ileal pouch-anal anastomosis (IPAA). \nMethods: Retrospective assessment of UC patients registered in the MSH surgical database, questionnaire, chart review and serological and genetic analysis of blood sample. \nResults: There was a positive association between gASCA antibodies, anti-L, smoking status and axial arthritis/ankylosing spondylits with a Crohn’s Disease (CD)-like phenotype post-op in UC/IPAA patients. Associations between alleles of selected genes including ECM1, PTPN2, and CD14 and post-operative phenotype were identified. \nConclusions: gASCA is typically associated with CD rather than UC which raises the possibility that gASCA positivity may delineate a subset of UC patients at risk for developing a CD-like phenotype after IPAA. The identification of genotype/phenotype associations in UC/IPAA will help to find those at risk for poor post-operative outcome. Prospective studies are needed to confirm these findings.

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.
