“…The incidence within the first 12 months after ileostomy closure was as high as 40% according to a clinical trial [16]. In patients with pouchitis, 70% had the initial episode during the first 12 months after ileostomy closure [17], although late-onset pouchitis can occur years afterwards. …”

Background: Pouchitis is the most common long-term complication in ulcerative colitis that follows restorative proctocolectomy. Clinical evidence suggests that dysbiosis plays a key role in its pathogenesis. Methods: Current literature on the topic was reviewed. A therapeutic approach was proposed based on the literature along with personal experience from the subspecialty Pouchitis Clinic. Results: Pouchitis represents a disease spectrum in the reservoir, with ranging etiopathogenesis, clinical phenotypes, disease courses and prognoses. Dysbiosis plays a critical role in disease initiation and progress, with antibiotic therapy as the mainstay for treatment. On the other hand, superimposed infection from pathogens contributes to flare-up of the disease. Pouchitis can progress into an ‘IBD-like’ condition, requiring anti-inflammatory, immunomodulator or even biological therapy. Conclusion: Pouchitis represents a unique form of IBD. Investigation on the evolution from an antibiotic-responsive phenotype to chronic antibiotic-refractory pouchitis may shed some light on the pathogenesis and therapeutic targets of IBD.

“…The reported cumulative frequencies of developing pouchitis 10-11 years after IPAA are 23-46%, and approximately 50% of patients with UC who undergo IPAA develop at least one episode of pouchitis [2,3,4,5]. Approximately 20-45% of patients diagnosed with pouchitis have chronic inflammation that requires long-term courses of antibiotics and other medications [2,6,7,8]. …”

“…[2,5,8,9,10,11,12,13,14,15,16]. Some of these studies evaluated predictive factors for the development of both acute and chronic pouchitis in combination [2,9,11], but other studies focused on predictive factors for acute and chronic pouchitis individually [8,10,12,13,14,15,17,18]. It was suggested that acute and chronic pouchitis may have different risk factors and pathogeneses [8,12,13].…”

Background: No previous studies have examined predictive factors for chronic pouchitis after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) with consideration of changes in pouchitis subtypes during follow-up. This study evaluated the independent predictive factors for chronic pouchitis. Methods: A total of 244 consecutive patients who underwent IPAA were enrolled. We assessed the possible associations between pouchitis and clinical factors using Cox proportional hazard regression. Results: 231 patients met the inclusion criteria. 66 (28.5%) patients developed pouchitis. In 9 of 44 (20.4%) patients, antibiotic-responsive pouchitis at the first episode changed into chronic pouchitis after the occurrence of a subsequent episode. The median duration from occurrence of antibiotic-responsive pouchitis to alteration into chronic pouchitis was 502 (range 147-1,697) days. Overall pouchitis was finally classified into 35 acute pouchitis and 31 chronic pouchitis cases. Multivariate analysis revealed that a ≥7.5-g cumulative steroid dose before colectomy and a ≥500-mg monthly steroid dose just before colectomy were significant predictive factors for chronic pouchitis (p = 0.0001 and 0.0095, respectively). Conclusion: Patients with UC and a higher cumulative steroid dose before colectomy or higher monthly steroid dose just before colectomy may have a predictive factor for developing chronic pouchitis.

BackgroundUlcerative colitis (UC) is the most common form of inflammatory bowel disease in the UK. UC can have a considerable impact on patients’ quality of life. The burden for the NHS is substantial.ObjectivesTo evaluate the clinical effectiveness and safety of interventions, to evaluate the incremental cost-effectiveness of all interventions and comparators (including medical and surgical options), to estimate the expected net budget impact of each intervention, and to identify key research priorities.Data sourcesPeer-reviewed publications, European Public Assessment Reports and manufacturers’ submissions. The following databases were searched from inception to December 2013 for clinical effectiveness searches and from inception to January 2014 for cost-effectiveness searches for published and unpublished research evidence: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and NHS Economic Evaluation Database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science and Bioscience Information Service Previews. The US Food and Drug Administration website and the European Medicines Agency website were also searched, as were research registers, conference proceedings and key journals.Review methodsA systematic review [including network meta-analysis (NMA)] was conducted to evaluate the clinical effectiveness and safety of named interventions. The health economic analysis included a review of published economic evaluations and the development of a de novo model.ResultsTen randomised controlled trials were included in the systematic review. The trials suggest that adult patients receiving infliximab (IFX) [Remicade®, Merck Sharp & Dohme Ltd (MSD)], adalimumab (ADA) (Humira®, AbbVie) or golimumab (GOL) (Simponi®, MSD) were more likely to achieve clinical response and remission than those receiving placebo (PBO). Hospitalisation data were limited, but suggested more favourable outcomes for ADA- and IFX-treated patients. Data on the use of surgical intervention were sparse, with a potential benefit for intervention-treated patients. Data were available from one trial to support the use of IFX in paediatric patients. Safety issues identified included serious infections, malignancies and administration site reactions. Based on the NMA, in the induction phase, all biological treatments were associated with statistically significant beneficial effects relative to PBO, with the greatest effect associated with IFX. For patients in response following induction, all treatments except ADA and GOL 100 mg at 32–52 weeks were associated with beneficial effects when compared with PBO, although these were not significant. The greatest effects at 8–32 and 32–52 weeks were associated with 100 mg of GOL and 5 mg/kg of IFX, respectively. For patients in remission following induction, all treatments except ADA at 8–32 weeks and GOL 50 mg at 32–52 weeks were associated with beneficial effects when compared with PBO, although only the effect of ADA at 32–52 weeks was significant. The greatest effects were associated with GOL (at 8–32 weeks) and ADA (at 32–52 weeks). The economic analysis suggests that colectomy is expected to dominate drug therapies, but for some patients, colectomy may not be considered acceptable. In circumstances in which only drug options are considered, IFX and GOL are expected to be ruled out because of dominance, while the incremental cost-effectiveness ratio for ADA versus conventional treatment is approximately £50,300 per QALY gained.LimitationsThe health economic model is subject to several limitations: uncertainty associated with extrapolating trial data over a lifetime horizon, the model does not consider explicit sequential pathways of non-biological treatments, and evidence relating to complications of colectomy was identified through consideration of approaches used within previous models rather than a full systematic review.ConclusionsAdult patients receiving IFX, ADA or GOL were more likely to achieve clinical response and remission than those receiving PBO. Further data are required to conclusively demonstrate the effect of interventions on hospitalisation and surgical outcomes. The economic analysis indicates that colectomy is expected to dominate medical treatments for moderate to severe UC.Study registrationThis study is registered as PROSPERO CRD42013006883.FundingThe National Institute for Health Research Health Technology Assessment programme.
