Case Report: Secukinumab (Interleukin-17 Inhibitor) and Ulcerative Colitis Flare – the Double-Edged Sword
Bibliographic record
Abstract
Introduction: Secukinumab is an interleukin (IL)-17A inhibitor approved for psoriatic arthritis (PsA) and ankylosing spondylitis (AS). Its use has been reported to be associated with inflammatory bowel disease (IBD) flare and new onset. Case Presentation: We report a case of a 56-year-old woman with longstanding ulcerative colitis (UC) in remission, who developed a severe UC flare after initiating secukinumab for refractory PsA. She presented with extensive ulcerations, systemic inflammation needing hospitalization, and change of treatment to risankizumab. Conclusion: This case highlights the emerging evidence of IL-17A blockade in IBD, potentially leading to adverse events, and adds to the growing body of evidence regarding the management of such complications with novel therapeutic approaches in severe cases. Physicians should be aware of this possibility when using IL-17A blockade in patients with pre-existing IBD.

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.
