Background Pouchitis and other inflammatory disorders of the pouch (IDP), such as Crohn′s-like disease of the pouch (CDP), are frequent in patients operated for a previous diagnosis of ulcerative colitis. Many different therapies have been used, but the effectiveness of immunosupresants (IMM) has been poorly explored in this setting. Our aim was to evaluate the use, efficacy and safety of IMM in patients with pouchitis or another IDP. Methods Retrospective and multicentric study of a Spanish cohort of pouch-carrying patients with previous diagnosis of ulcerative colitis, and subsequent diagnosis of IDP, following ECCO diagnostic criteria. Patients who used IMM to treat these conditions were selected. Clinical effectiveness was evaluated at long-term. We defined clinical remission as returning to the previous stool frequency, no pain or defecatory urgency, clinical response as the improvement in these parameters without the achievement of remission, and non-response as no improvement or worsening symptoms. Endoscopic response was evaluated when possible using modified pouchitis disease activity index (PDAI) endoscopic subscore. Adverse events were collected. We used descriptive statistics. Results In the overall cohort of 338 patients with IDP, 93 (27%) were treated with IMM. Of those, 57% males, median age 40 (20-71) ys, and 72% non-smokers. Colectomy was performed at a median age of 31 (18-63) ys and IPD was diagnosed 25 (1-235) months after ileostomy closure. IMM used were thiopurines (n=86), methotrexate (n=4), cyclosporine (n=2) and tacrolimus (n=1). IMM were used as monotherapy in 66 (71%) cases and were indicated as treatment of pouchitis (n=60, 65%), CDP (n=32, 34.4%) and cuffitis (n=1, 1%). Effectiveness was evaluated only for thiopurine monotherapy (n=62). After a median follow-up of 23 (1-234) months, clinical remission was achieved in 31%, clinical response in 31% and non-response in 38% (Figure 1). There were no differences in effectiveness between pouchitis and CDP (63.9% vs 57.7%, p= 0.62). Endoscopic response was evaluated in 19 (30.6%) cases. After a median of 9 months of follow-up median PDAI endoscopic subscore dropped from 3 (range 2-4) to 1 (range 0-3), (Figure 2). Adverse events related with treatment appeared in 28 patients (45%). Thiopurines were discontinued in 39 cases (63%) due to failure (17), toxicity (16) and long remission (6 cases). Conclusion In our cohort, thiopurines were used in 27% of patients with IDP, with long-term benefit (remission or response) in around two-thirds of them. This therapy could be one more option to manage these disorders.

Background Pouchitis and Crohn′s-like disease of the pouch (CDP) can be refractory to conventional therapy. Evidence of biological therapy has been rarely reported in large patient cohorts. We explored the use and effectiveness of these therapies and compared the success of a second biologic after antiTNF failure. Methods This is a retrospective RESERVO study of the Spanish cohort of GETECCU, that included patients operated for ulcerative colitis, with pouch construction, and subsequent diagnosis of pouchitis, CDP or cuffitis second ECCO diagnostic criteria1. Patients treated with antiTNF, Vedolizumab and/or Ustekinumab were selected. Clinical effectiveness was evaluated at long-term. We defined clinical remission as returning to the previous stool frequency, no pain or defecatory urgency, clinical response as the improvement in these parameters without the achievement of remission and non-response as no change or worsening of these symptoms. We also compared the effectiveness of second biologic (antiTNF vs vedolizumab-ustekinumab) after antiTNF failure, using descriptive and comparative statistics. Results The cohort comprised 145 patients. Demographic and clinical characteristics are represented in Table 1. A total of 232 biologic therapies were indicated. Of the total cohort, 60 (41.3%), 21 (14.4%) and 6 (4.1%) used two, three and four lines, respectively. Biologics used were Infliximab (n=95), Adalimumab (n=69), Vedolizumab (n=35), Ustekinumab (n=26) and Golimumab (n=7). Therapy characteristics, clinical effectiveness, need for intensification, discontinuation, and therapy duration for each biological therapy are represented in Table 2. Global rates of clinical remission, response, non-response and loss of response to a first biologic were 21.8%, 27.5%, 21.1% and 29.6%. Female gender was the only factor associated with effectiveness to a first biologic in univariate analysis (OR 2.16, CI 1.08–4.32, p 0.027). There were no significant differences regarding efectiveness between type of pouch disorder (pouchitis vs CDP, 51.6 vs 47.6%, p 0.48) or biologic agents. Thirty-nine patients received a second biologic after prior antiTNF failure (28 a second antiTNF and 11 non-antiTNF: 6 Vedolizumab, 5 Ustekinumab). Basal characteristics in this subgroup showed no significant differences. Clinical response (21.4 vs 63.6%, p 0.02) and discontinuation therapy rates (82.2 vs 54.5 %, p 0.04) after 11 months showed a more favorable profile for non-antiTNF therapy. Conclusion Biologics represent an effective option in the management of pouchitis and Crohn′s like disease of the pouch. Despite our small sample size, non-antiTNF therapy could be the best option after antiTNF failure. 1Fernando Magro. J Crohns Colitis 2017; 11(6): 649–670.

Background & aims: Disease outcome has been found to be poorer in familial inflammatory bowel disease (IBD) than in sporadic forms, but assessment of phenotypic concordance in familial IBD provided controversial results. We assessed the concordance for disease type and phenotypic features in IBD families. Methods: Patients with familial IBD were identified from the IBD Spanish database ENEIDA. Families in whom at least two members were in the database were selected for concordance analysis (K index). Concordance for type of IBD [Crohn's disease (CD) vs. ulcerative colitis (UC)], as well as for disease extent, localization and behaviour, perianal disease, extraintestinal manifestations, and indicators of severe disease (i.e., need for immunosuppressors, biological agents, and surgery) for those pairs concordant for IBD type, were analyzed. Results: 798 out of 11,905 IBD patients (7%) in ENEIDA had familial history of IBD. Complete data of 107 families (231 patients and 144 consanguineous pairs) were available for concordance analyses. The youngest members of the pairs were diagnosed with IBD at a significantly younger age (p < 0.001) than the oldest ones. Seventy-six percent of pairs matched up for the IBD type (kappa = 0.58; 95%CI: 0.42-0.73, moderate concordance). There was no relevant concordance for any of the phenotypic items assessed in both diseases. Conclusions: Familial IBD is associated with diagnostic anticipation in younger individuals. Familial history does not allow predicting any phenotypic feature other than IBD type. (C) 2013 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.
