Background: Information on efficacy and predictors of response to adalimumab in ulcerative colitis (UC) clinical practice is limited., Aim: Assessment of response to adalimumab and its predictors in an observational cohort study., Methods: Retrospective cohort study based on data obtained from ENEIDA registry. All patients diagnosed with UC treated with adalimumab were included. Response to adalimumab was evaluated at weeks 12, 28, and 54 according to the partial Mayo score, and requirement of colectomy until end of follow-up., Results: 48 patients with UC treated with adalimumab were included; 39 (81.3%) had previously received infliximab. Response rates at weeks 12, 28 and 54 were 70.8%, 43.2% and 35% respectively. Response to prior treatment with infliximab was the only predictive factor of response to adalimumab at week 12, which was obtained in 90% of infliximab remitters, 53.8% of responders and 33.3% of primary non-responders (p=0.01). Colectomy was required in 11 patients (22.9%), after a mean time of 205 days. The only clinical independent predictor of colectomy was non-response to adalimumab at week 12: colectomy rates were 5/34 (14.7%) in responders and 6/14 (42.9%) in non-responders (p=0.035), time free of colectomy was significantly reduced in non-responders (p=0.01). Adalimumab withdrawal due to adverse events occurred in 4.2% of patients., Conclusion: This study shows that adalimumab is an effective treatment in patients with UC. If used as a second anti-TNF, previous achievement of remission with the first anti-TNF predicts response, and failure to achieve response at week 12 predicts colectomy., (Copyright © 2012 European Crohn's and Colitis Organisation.

Aim: In refractory pouchitis, infliximab (IFX) has been used as rescue therapy; however, there is no clinical evidence for the use of adalimumab (ADA). The aim of this study was to report the efficacy of ADA in patients with refractory pouchitis previously treated with IFX., Methods: A retrospective, open-label, case series was designed. Patients with chronic refractory pouchitis treated with ADA were included. All patients were previously treated with IFX. The short-term and mid-term efficacy of ADA was evaluated., Results: Eight patients with chronic refractory pouchitis treated with ADA were included. After 8 weeks, 13% of the patients achieved remission and 62% showed a clinical response. At week 26, 13% achieved remission and 38% showed a clinical response. At week 52, 50% of the patients avoided a permanent ileostomy but only 25 achieved remission., Conclusion: ADA treatment was found to be an alternative for patients with chronic refractory pouchitis previously treated with IFX.
