Probiotic preparation VSL#3 induces remission in children with mild to moderate acute ulcerative colitis: A pilot study
Bibliographic record
Abstract
BACKGROUND: Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) that has periods of exacerbated symptoms and periods that are symptom-free. The treatment of active UC with probiotic bacteria could possibly induce remission. We evaluated the clinical efficacy and safety profile of probiotic preparation VSL#3 in the treatment of mild to moderate acute UC in the pediatric population. METHODS: Eighteen eligible patients between the ages of 3-17 with mild to moderate acute UC received open-label VSL#3 daily in 2 divided doses for 8 weeks. The disease activity pre- and post-VSL#3 therapy was assessed by the simple clinical colitis activity index (SCCAI); Mayo ulcerative colitis endoscopic score; inflammatory markers: erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP); serum cytokine profiling; and rectal tissue microbial profiling done at baseline and at week 8. RESULTS: Thirteen patients completed 8 weeks of VSL#3 treatment and 5 patients were withdrawn due to lack of improvement. Remission (defined as SCCAI <or=3) was achieved in 56% of children (n = 10); response (decrease in SCCAI >or=2, but final score <or=5) in 6% (n = 1); and no change or worsening in 39% (n = 7). Post-VSL#3 treatments demonstrated a bacterial taxonomy change in rectal biopsy. The VSL#3 was well tolerated in clinical trials and no biochemical and clinical adverse effects attributed to VSL#3 were identified. CONCLUSIONS: Treatment of pediatric patients diagnosed with mild to moderate UC with VSL#3 resulted in a remission rate of 56% and a combined remission/response rate of 61%.

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.
