Upadacitinib as rescue therapy for corticosteroid failure acute severe ulcerative colitis: an Asian experience from Taiwan
Bibliographic record
Abstract
PURPOSE: Acute severe ulcerative colitis (ASUC) is a medical emergent condition, and approximately one-third of patients with ASUC do not respond to corticosteroid. Whether small molecule drugs are efficient and safe for salvage therapy of ASUC is not well-understood. METHODS: Consecutive patients with ASUC who failed responding to first-line corticosteroid were retrospectively enrolled. Clinical, laboratory, endoscopic, and pathological data were analyzed. RESULTS: Five Asian male patients (median age of 38.9 years old) with ASUC who received salvage therapy with upadacitinib were enrolled. The mean (± standard deviation) disease duration was 3.44 (± 3.30, 0.53 ~ 7.88) years. Baseline Montreal disease extent, C-reactive protein, and erythrocyte sedimentation rate were four (80%) E3 and one (20%) E2 disease, 40.54 (± 74.26) mg/dl, and 24.50 (± 19.09) mm/h, respectively. Daily upadacitinib 45 mg was prescribed for 56 days in all patients. Clinical response, clinical remission, corticosteroid-free remission, and endoscopic improvement at weeks 8 and 12 were achieved in five (100%) and five (100%), four (80%) and five (100%), four (80%) and five (100%), and four (80%) and five (100%) patients, respectively. One (20%) patient achieved histo-endoscopic remission at week 24. None of them had re-hospitalization or colectomy during the follow-up period but one patient developed penile simplex-1 infection which resolved after topical antiviral ointment without upadacitinib discontinuation. CONCLUSIONS: Upadacitinib is an efficient salvage therapy for patients with ASUC. Further investigations are essential to assess long-term durability, safety profile, and viability as a bridging regimen in the treatment of ASUC.

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.
