Baseline Characteristics of Adult Patients Treated and Never Treated with Teduglutide in a Multinational Short Bowel Syndrome and Intestinal Failure Registry
Bibliographic record
Abstract
The Short Bowel Syndrome (SBS) Registry (NCT01990040) is a multinational real-world study evaluating the long-term safety of teduglutide in patients with SBS and intestinal failure (SBS-IF) in routine clinical practice. This paper describes the study methodology and baseline characteristics of adult patients who have (ever-treated) or have never (never-treated) received teduglutide. A total of 1411 adult patients (679 ever-treated; 732 never-treated) were enrolled at 124 sites across 17 countries. The mean (standard deviation [SD]) age at enrollment was 55.4 (15.46) years, and 60.2% of patients were women. Crohn's disease was the most common cause of major intestinal resection in both ever-treated (34.1%) and never-treated patients (20.4%). A similar proportion of ever-treated and never-treated patients had a prior history of colorectal polyps (2.7% vs. 3.6%), whereas proportionally fewer ever-treated patients reported a history of colorectal cancer (1.8% vs. 6.2%) or any malignancy (17.7% vs. 30.0%) than never-treated patients. Never-treated patients received a numerically greater mean (SD) volume of parenteral nutrition and/or intravenous fluids than ever-treated patients (12.4 [8.02] vs. 10.1 [6.64] L/week). Ever-treated patients received a mean teduglutide dosage of 0.05 mg/kg/day. This is the first report of patient baseline characteristics from the SBS Registry, and the largest cohort of patients with SBS-IF to date. Overall, ever-treated and never-treated patients had similar baseline characteristics. Differences between treatment groups may reflect variations in patient selection and degree of monitoring.

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.
