  4. • In UC, mucosal healing is associated with better outcomes • The degree of healing influences the outcomes UC = ulcerative colitis

  9. • In CD mucosal healing is associated with better outcomes • The relationship between the degree of endoscopic healing and outcomes – is not yet established – may be influenced by treatments CD = Crohn’s disease

  15. • In CD mucosal healing is one of the predictors of relapse after anti-TNF withdrawal • Mucosal healing does not predict relapse after corticosteroid or azathioprine withdrawal TNF = tumour necrosis factor

  16. Relapse upon infliximab discontinuation (STORI) Treated with combined scheduled infliximab+immunosuppressive therapy for at ≥1 year In stable remission without steroid for >6 months Factors predicting time to relapse: male gender, surgery, steroids, Hb, WBC, hsCRP, CDEIS Global and individual curves according to predictive index 1.0 Index # relapse 0.8 ≤ 4 2/19 Proportion =5 10/36 0.6 Global 40/107 0.4 =6 13/24 0.2 =7 25/28 0.0 0 3 6 9 12 15 18 21 24 27 30 33 Time since inclusion (months) # at risk: 115 102 79 63 51 47 39 27 20 12 9 HsCRP = high-sensitivity C-reactive protein; CDEIS = CD endoscopic index of severity Louis E, et al. Gastroenterology 2012;142:63-70.

  17. Relapse after steroid withdrawal according to endoscopic remission Prospective study in active colonic or ileocolonic CD patients (n=147), treated with prednisolone 1 mg/kg/d.

  20. What is the definition of mucosal healing ? Ulcerative colitis Crohn’s disease • Normal, improved, no change or • No mucosal ulceration in any of 5 worse segments • Severity of bleeding without • Absence of mucosal ulceration considering ulcers • Disappearance of all ulcerative • UC- DAI≤1 lesions • Mayo≤ 1 • CDEIS ≤2, ≤3, ≤4, ≤6 • UCEIS < ? • SES- CD ≤5 • Rutgeerts score ≤i1 Need for homogenous definition of endoscopic healing

  21. What is the prognostic endoscopic threshold in CD? 38.4 Need for major abdominal 40 30 surgeries 20 14.1 14.0 10 n=12 n=6 n=12 0 Complete Partial mucosal No mucosal mucosal healing healing healing (n=85) (n=43) (n=86) Schnitzler F, et al. Inflamm Bowel Dis 2009;15:1295 – 301

  25. UC: is rectosigmoidoscopy enough to assess mucosal healing ? Proctitis Left-sided colitis Pancolitis • • • Diarrhoea Tenesmus, urgency Bloody diarrhoea • Weight loss • • Faecal incontinence Sometimes proximal • Fever • constipation Passage of mucus and fresh • Clinically significant blood loss blood • Abdominal pain

  26. Colon capsule: next tool for assessing mucosal healing in IBD ? Erosions, oedema, erythema Erosions Performances of colon capsule in detecting inflammation with endoscopy as gold standard Diagnosis of active UC lesions 68 True positive, n 5 False positive, n 15 True negative, n Pseudo polyps Mosaic pattern 8 False negative, n 96 Total, N 89 (80 – 95) Sensitivity, % (95% CI) 75 (51 – 90) Specificity, % (95% CI) 93 (84 – 97) Positive predictive value, % (96% CI) 65 (43 – 83) Negative predictive value, % (96% CI) CI = confidence interval Ksung J, et al Endoscopy 2011
