abstract

  • BACKGROUND: Associations between patient-reported outcomes and mucosal healing have not been established in ulcerative colitis (UC). AIM: To evaluate relationships of rectal bleeding and stool frequency with mucosal healing and quality of life (QoL) in patients with UC in two Phase 3 studies (ULTRA 1 and 2). METHODS: Associations of patient-reported rectal bleeding and stool frequency subscores with mucosal healing (Mayo endoscopy subscore = 0 or 0/1) and QoL [inflammatory bowel disease questionnaire (IBDQ)] were assessed in adalimumab-randomised patients (160/80 mg at Weeks 0/2 followed by 40 mg biweekly or weekly) at Weeks 8 (n = 433) and 52 (n = 299), and in patients with mucosal healing [endoscopy subscore = 0 (n = 17); 0/1 (n = 52)] at Weeks 8 and 52. RESULTS: At Week 8, the positive predictive values (PPVs) of rectal bleeding subscore = 0, stool frequency subscore = 0 or both scores = 0 for endoscopy subscore = 0/1 were 69%, 84% and 90% respectively; all proportions increased at Week 52. Equivalent PPVs for these subscores in patients with endoscopy subscore = 0 were 26%, 37% and 46% respectively. Among patients with endoscopy subscore = 0 at Week 8, 87% reported no rectal bleeding, while only 29% reported normal stool frequency; these proportions had increased to 94% and 41% respectively, at Week 52. Among patients with mucosal healing, IBDQ scores trended highest for patients with both rectal bleeding and stool frequency subscores = 0. CONCLUSIONS: Absence of rectal bleeding and normal stool frequency are often predictive of mucosal healing and QoL, but complete normalisation of stool frequency is encountered rarely in patients with mucosal healing.
