Infliximab Salvage Therapy after Cyclosporine in an Acute Flare of Chronic Ulcerative Colitis
Bibliographic record
Abstract
Although infliximab (Remicade, Schering Canada Inc, Quebec) therapy has been well studied in steroid refractory Crohn's disease, its use remains controversial in chronic ulcerative colitis. A 24-year-old woman with a 14-year history of well controlled left sided ulcerative colitis presented with an acute flare. Clinical, endoscopic and biopsy evidence of an acute flare of ulcerative pancolitis were present. There was no response to intravenous steroids but improvement was seen after receiving 14 days of intravenous cyclosporine (4 mg/kg/day continuous infusion). The patient was discharged from hospital with azathioprine (2.5 mg/kg/day) and low dose oral cyclosporine (4 mg/kg/day). She presented with worsening symptoms seven days after discharge. Because of the patient's unwillingness for surgery, she instead received two injections of infliximab 5 mg/kg at week 0 and week 2. An initial response occurred, but her clinical improvement was not durable. Colectomy was performed four weeks later. This is the first report of infliximab as a salvage therapy in an acute flare of chronic ulcerative colitis following failure of cyclosporine.

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.
