Description détaillée
Patients with UC requiring endoscopy (colonoscopy or recto sigmoidoscopy) in their management and with endoscopic activity (Mayo endoscopic score ≥ 2) will be offered inclusion in this study.
Blood and faecal samples will be taken in addition to the usual care measurements for the determination of biomarkers under study. Routine care biopsies will be performed in each patient during endoscopy to assess histologic activity.
Because of endoscopic activity, treatment will be changed (start, increase or change treatment) according to current recommendations. After several weeks of treatment (8 ± 4 weeks for 5-ASA and corticosteroids, 12 to 24 weeks for immunosuppressants and 12 ± 2 weeks for biotherapies), patients will have an evaluation performed by endoscopy (colonoscopy or rectosigmoidoscopy) with biopsies for histological analysis (routine care). Blood and faecal samples will be taken in addition to the usual care measurements (blood count, albumin, CRP and faecal calprotectin...) for the determination of biomarkers under study.
Every patient will have a follow-up every 3 months for 1 year with clinical evaluation, blood and faecal biomarker assays and each patient will have a new endoscopic evaluation with biopsies for histological analysis at 12 months.
