Cure8 research brief
Why This Matters
Perianal fistulizing Crohn's disease is difficult to treat and many patients have failed anti-TNF therapy. Evidence that ustekinumab achieves high clinical fistula response and remission rates in a real-world multicenter cohort could influence treatment choices and discussions about expected outcomes.
Who Should Pay Attention
Adult Crohn's patients with perianal fistulas, clinicians who manage complex perianal Crohn's disease, and researchers studying medical and surgical approaches to fistulizing disease.
Study Snapshot
What To Know
This paper pooled real-world data from 163 patients treated with UST between 2020–2023 and reports improvements in inflammatory blood markers (CRP, ESR) and hemoglobin. Clinical response and remission rates reported are based on the study's clinical definitions; objective MRI-confirmed fistula healing was much lower than clinical response rates.
The authors performed multivariate analyses to identify independent predictors of healing and built a predictive nomogram (AUC 0.852 for 24-week remission) intended to help individualize treatment decisions.
Safety signals were limited in this cohort (adverse event rate 7.4%) and no severe safety issues were reported in the abstracted data, but retrospective design and follow-up length are important to consider.
Keep In Mind
This is a retrospective multicenter study (2020–2023) with median 15-month follow-up and an abstract-level structured summary. MRI-confirmed healing was much lower than clinical remission, and retrospective designs can include selection and measurement biases. The nomogram requires external validation before routine clinical use.
