BACKGROUND & AIMS: Many patients with inflammatory bowel diseases (IBD) have ongoing bowel symptoms of diarrhea or abdominal pain despite mucosal healing. We investigated whether impaired intestinal permeability contributes to these symptoms. METHODS: We performed a prospective study of intestinal permeability, measured by endoscopic confocal laser endomicroscopy in 110 consecutive subjects (31 with ulcerative colitis [UC], 57 with Crohn's disease [CD], and 22 healthy individuals [controls]) in Sydney, Australia from May 2009 and September 2015...

Background and study aims Current guidelines recommend the use of pancolonic chromoendoscopy for surveillance of patients with inflammatory bowel disease (IBD). It is currently unknown whether low grade dysplasia (LGD) found using chromoendoscopy carries a similar risk of high grade dysplasia (HGD) or colorectal cancer (CRC) compared with LGD detected using white-light endoscopy (WLE). The aim of this study was to compare the risk of advanced neoplasia, a combined endpoint of HGD and CRC, during follow-up after detection of lesions containing LGD identified with either chromoendoscopy or WLE...

Oral mesalazine (also known as mesalamine) is a 5-aminosalicylic acid compound used in the treatment of mild to moderate ulcerative colitis, with high rates of efficacy in induction and maintenance of remission. The therapeutic effect of mesalazine occurs topically at the site of diseased colonic mucosa. A myriad of oral mesalazine preparations have been formulated with various drug delivery methods to minimize systemic absorption and maximise drug availability at the inflamed colonic epithelium. It remains unclear whether different oral mesalazine formulations are bioequivalent...

BACKGROUND & AIMS: Giant inflammatory polyposis (GIP), characterized by mass-like agglomerations of inflammatory polyps, is a rare complication of inflammatory bowel disease (IBD). We reviewed a series of cases of GIP to determine its diagnostic impact on the clinical and pathologic distinction between ulcerative colitis (UC) and colonic Crohn's disease (CD). METHODS: All colons with GIP resected over a 13-year period were identified prospectively and the corresponding clinical and pathologic records were reviewed...

BACKGROUND: Mucosal healing (MH) as a treatment target for ulcerative colitis is of growing interest because it is associated with improved clinical outcomes. However, the feasibility and probability of reaching MH in clinical practice is unknown. We therefore evaluated the feasibility of "treating to target" according to endoscopic findings to reach MH. METHODS: All endoscopic outcomes of patients with ulcerative colitis followed in a single inflammatory bowel disease unit from 2011 to 2012 were reviewed and subsequent therapeutic management...

Crohn's disease is characterised by recurrent and/or chronic inflammation of the gastrointestinal tract leading to cumulative intestinal tissue damage. Treatment tailoring to try to prevent this tissue damage as well as achieve optimal benefit/risk ratio over the whole disease course is becoming an important aspect of Crohn's disease management. For decades, clinical symptoms have been the main trigger for diagnostic procedures and treatment strategy adaptations. However, the correlation between symptoms and intestinal lesions is only weak...

Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, has multifactorial aetiology with complex interactions between genetic and environmental factors. Over 150 genetic loci are associated with IBD. The genetic contribution of the majority of those loci towards explained heritability is low. Recent studies have reported an increasing spectrum of human monogenic diseases that can present with IBD-like intestinal inflammation. A substantial proportion of patients with those genetic defects present with very early onset of intestinal inflammation...

BACKGROUND: The impact of pregnancy on the course of IBD is still controversial. AIM: To investigate the impact of pregnancy on IBD and to search for factors with potential impact on remission. METHODS: Pregnant IBD women from 12 European countries were enrolled between January 2003 and December 2006 and compared at conception (1:1) with nonpregnant IBD women. Data on disease course were prospectively collected at each trimester during pregnancy and in the postpartum (6 months) using a standardised questionnaire...

BACKGROUND: Tumour necrosis factor (TNF)-antagonists have an established role in the treatment of inflammatory bowel diseases (IBDs), however, subtherapeutic drug levels and the formation of anti-drug antibodies (ADAs) may decrease their efficacy. AIM: The evidence supporting the use of therapeutic drug monitoring (TDM) based clinical algorithms for infliximab (IFX) and their role in clinical practice will be discussed. METHODS: The literature was reviewed to identify relevant articles on the measurement of IFX levels and antibodies-to-infliximab...

BACKGROUND: Up to 40% of patients who present with acute severe ulcerative colitis (UC) fail to make an adequate response to intravenous corticosteroids. Ciclosporin or infliximab are currently employed as salvage therapy in this clinical scenario. AIM: To compare clinical outcomes in patients treated with ciclosporin or infliximab in the setting of steroid-refractory acute severe UC. METHODS: A prospective study of 83 consecutive presentations of steroid-refractory acute severe UC from 1999 to 2009 was conducted...

BACKGROUND & AIMS: A small placebo-controlled trial reported the efficacy of mercaptopurine therapy for children newly diagnosed with Crohn's disease, yet little is known about the efficacy of early thiopurine therapy in adults. METHODS: We performed a prospective double-blind trial of adult patients with a recent (<8 weeks) diagnosis of Crohn's disease. Patients were randomly assigned to groups given azathioprine (2.5 mg · kg(-1) · day(-1), n = 68) or placebo (n = 63) at 31 hospitals from February 2006 to September 2009...

BACKGROUND: Recent evidence suggests that embryonated eggs of the porcine whipworm Trichuris suis ova (TSO) may be an effective treatment for inflammatory bowel disease (IBD). AIM: To assess the safety and tolerability of TSO following a single dose in patients with Crohn's disease. METHODS: This was a sequential dose-escalation (500, 2500 and 7500 viable embryonated TSO), randomised, double-blind, placebo-controlled study to evaluate the safety of a single dose of oral suspension TSO in patients with Crohn's disease...

BACKGROUND: Predictors of complicated Crohn's disease (CD), defined as stricturing or penetrating behaviour, and surgery have largely been derived from referral centre populations. AIM: To investigate whether serological markers, susceptibility genes or psychological characteristics are associated with complicated CD or surgery in a population-based cohort. METHODS: One hundred and eighty-two members of the Manitoba IBD Cohort with CD phenotyped using the Montreal classification underwent genetic and serological analysis at enrolment and after 5 years...

BACKGROUND: Chronic active ulcerative colitis (UC) is associated with significant morbidity, loss of productivity, increased colorectal cancer risk and cost. Up to 18% of patients suffer chronic active disease, with 30% requiring colectomy at 10 years. The management remains challenging given the relatively few clinical trials in this area. AIM: To summarise the evidence regarding optimal management strategies for patients with chronic active UC of differing disease extents and degrees of treatment refractoriness...

BACKGROUND: Although infliximab is widely accepted as a therapeutic option for inflammatory bowel disease, its therapeutic efficacy for the treatment of intestinal Behçet's disease (BD) is unknown. We investigated the short-term and long-term response rates to infliximab in intestinal BD and predictive factors of sustained treatment response following infliximab treatment. METHODS: This study was conducted using a retrospective noncontrolled review of medical records from 8 tertiary hospitals in Korea...

BACKGROUND: For patients with ulcerative colitis (UC) who have colonoscopy while their disease is in clinical remission, the clinical implications of finding histologic abnormalities of colitis are not clear. METHODS: We reviewed the medical records of patients with UC who had elective colonoscopy at our VA Medical Center while their UC was in clinical remission and who had at least 6 months of follow-up data available. The Mayo endoscopic subscore was used to assess endoscopic disease activity...
