Impact of Bowel Urgency on Quality of Life and Clinical Outcomes in Patients With Ulcerative Colitis
Bibliographic record
Abstract
Background: Bowel urgency is commonly experienced by patients with ulcerative colitis (UC) and is associated with reduced health-related quality of life (QoL). Mirikizumab, a humanized monoclonal antibody directed against the p19 subunit of IL-23, significantly reduced bowel urgency in a double-blind, randomized, placebo-controlled Phase 2 clinical trial in patients with moderate-to-severe UC (NCT02589665). Methods: = 249) reported symptoms including absence or presence of bowel urgency. Absence of urgency was defined as no urgency for the 3 consecutive days prior to each scheduled visit. Missing urgency data were imputed as present. After 12 weeks of induction treatment, patients who achieved clinical response continued maintenance mirikizumab treatment through Week 52. We assessed the relationship of urgency with QoL, clinical outcomes, and inflammatory biomarkers at Weeks 12 and 52. Results: Patients with absence of urgency demonstrated significantly greater improvement in Inflammatory Bowel Disease Questionnaire (IBDQ) scores even after adjusting for rectal bleeding (RB) and stool frequency (SF), significantly higher rates of all clinical outcomes at Weeks 12 and 52, and a greater decrease in inflammatory biomarkers C-reactive protein and fecal calprotectin compared to those with presence of urgency. Absence of urgency at Week 12 was associated with improved IBDQ scores at Week 52, while Week 12 RB or SF status was not. Conclusions: Absence of urgency is strongly associated with improvement in QoL as well as clinical measures of UC disease activity. These findings suggest urgency may be a useful surrogate marker of disease activity and an important treatment target for UC.

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.
