  • Whipping Crohn’s With Helminth Therapies' Not Yet
    • Authors: Caenepeel C; Van Assche G.
      Abstract: The complex pathogenesis of inflammatory bowel disease [IBD] remains largely unknown. Current theories support the hypothesis that IBD is a multifactorial disorder that results from an abnormal immune response to commensal and/or pathogenic gut microbes in a genetically susceptible host. Environmental factors are thought to trigger the onset or reactivation of the disease.1

  • Beyond Histological Remission: Intramucosal Calprotectin as a Potential
           Predictor of Outcomes in Ulcerative Colitis
    • Authors: Guirgis M; Wendt E, Wang L, et al.
      Abstract: Background and Aims:Histological remission and low faecal calprotectin are positive prognostic factors in ulcerative colitis [UC]. Intramucosal calprotectin [iMC], which can be readily determined by immunohistochemistry, has not so far been evaluated as a predictor of outcome in UC. We aimed to investigate the relationship between iMC and clinical, endoscopic, and histological measures of remission in UC, and the independent prognostic value of iMC.Methods:Ambulant patients with UC were recruited for a study comparing clinical activity indices. Sigmoidoscopy and biopsy were performed at the index visit. Clinical, endoscopic, and histological activity were scored and iMC semi-quantitatively measured using immunohistochemistry for the S100A8/9 heterodimer on colonic biopsies, scored as the mean number of positive cells in five high-power fields [HPF]. At the end of follow-up [6 years], data on steroid use, hospitalisation, and colectomy [‘adverse outcomes’] were collected.Results:iMC was determined in 83 patients and 20 controls, and correlated with clinical, endoscopic, and histological activity [r = 0.51, 0.65, 0.53, p > 0.001, respectively]. iMC was lowest (median 2.4, interquartile range [IQR]: 5.2–5, p < 0.001) in patients with concordance between clinical, endoscopic, and histological remission. Median iMC > 5/HPF was associated with adverse outcome (hazard ratio [HR] 3.36, confidence interval [CI] 1.58, 7.15, p < 0.001). Only 53%, 33%, and 25% of patients in histological remission with iMC > 5 cells/HPF avoided an adverse outcome after 1, 3, and 6 years, respectively.Conclusions:iMC was lowest in patients with concordant clinical, endoscopic, and histological remission. Median iMC > 5/HPF was associated with adverse outcomes despite histological remission. Therefore iMC is a potentially useful independent marker of activity.

  • Long-term Efficacy of Vedolizumab for Ulcerative Colitis
    • Authors: Loftus EV; Jr, Colombel J, Feagan BG, et al.
      Abstract: Background and Aims:The GEMINI long-term safety [LTS] study is a continuing phase 3 trial investigating the safety and efficacy of vedolizumab, an α4β7 integrin antagonist for ulcerative colitis [UC] and Crohn’s disease. We provide an interim analysis of efficacy in patients with UC.Methods:Patients from the C13004 and GEMINI 1 studies and a cohort of vedolizumab-naïve patients received open-label vedolizumab every 4 weeks. Interim data were collected from May 22, 2009 to June 27, 2013. Clinical response and remission, evaluated using partial Mayo scores, and health-related quality of life [HRQL] were assessed for up to 152 weeks of cumulative treatment in the efficacy population.Results:As of June 27, 2013, 63% of the efficacy population [n = 532/845] were continuing treatment. Among patients who responded to vedolizumab induction and had data available, 88% [n = 120/136] were in remission after 104 weeks of exposure (96% [n = 70/73] after 152 weeks). Among patients who withdrew from every-8-week vedolizumab maintenance in GEMINI 1 [n = 32] before week 52, increased dosing to every 4 weeks in GEMINI LTS resulted in response and remission rates of 41% and 28%, respectively, after 52 weeks, an increase from 19% and 6%, respectively, from before the dose increase. Similar benefits were demonstrated regardless of prior tumour necrosis factor-antagonist exposure. Durable benefits on HRQL were also observed.Conclusions:Patients with UC experienced clinical and HRQL improvements with continued vedolizumab treatment. Increased dosing frequency to every 4 weeks was beneficial in patients who had loss of response to 8-weekly dosing.

  • Characterisation of Mucosal Healing with Adalimumab Treatment in Patients
           with Moderately to Severely Active Crohn’s Disease: Results from the
           EXTEND Trial
    • Authors: Reinisch W; Colombel J, D’Haens G, et al.
      Abstract: Background and Aims:Mucosal healing [MH] is an important goal for patients with Crohn’s disease [CD], yet is incompletely characterised. We investigated whether MH differed by segments across the colon and ileum in patients who received adalimumab maintenance treatment in the EXTEND study.Methods:In this double-blind study in adults with moderate to severe ileocolonic CD and mucosal ulceration, all patients received adalimumab induction [Week 0, 160 mg; Week 2, 80 mg]. At Week 4, patients were randomised to 40 mg adalimumab or placebo every other week until Week 52. In this post-hoc analysis, MH was assessed by CD Endoscopic Index of Severity [CDEIS], Simple Endoscopic Score for CD [SES-CD], and Colonic and Ileal Global Histologic Disease Activity Scores [CGHAS/IGHAS].Results:Baseline endoscopic severity was similar across segments. At Week 52, mean changes in CDEIS surface involved and ulcerated surface were −68.5% to −90.6% in the rectum, sigmoid/left colon, and transverse colon compared with −22.3% to −50.0% in the right colon and ileum. Favourable shifts by Week 52 in ulcer size and ulcerated surfaces per SES-CD were more pronounced in the rectum, sigmoid/left colon, and transverse colon vs the right colon and ileum. At Week 52, CGHAS and IGHAS healing was more common in the colon [28.3%] vs the ileum [21.2%].Conclusions:This analysis suggests differing propensities of the ileocolonic segments to heal endoscopically during adalimumab treatment. In the sigmoid/left and transverse colon, higher MH rates may be achieved, compared with the ileum, in patients with moderate to severe CD.

  • African Americans and Short-Term Outcomes after Surgery for Crohn’s
           Disease: An ACS-NSQIP Analysis
    • Authors: Arsoniadis EG; Ho Y, Melton GB, et al.
      Abstract: Background:Previous reports on racial disparities in the treatment of Crohn’s disease [CD] in African American [AA] patients have shown differences in both medical and surgical treatments in this population. No study thus far has examined the effect of AA race on outcomes after surgery for CD.Methods:Utilizing the National Surgical Quality Improvement Program [NSQIP] Participant User File [PUF] for the years 2005–2013, we examined the effect of AA race on postoperative complications in patients with CD undergoing intestinal surgery.Results:AA patients had a significantly higher rate of complications overall compared to non-AA patients [23.5% vs 18.9%, p = 0.002]. Postoperative sepsis [10.9% vs 6.6%, p < 0.001] and surgical site infection [17.6% vs 14.8%, p = 0.037] were most significant. After adjustment for age, sex, preoperative disease severity and lifestyle factors [smoking], race remained a statistically significant factor in postoperative complication rate. Only after additional adjustment was made for comorbidities and American Society of Anesthesiologists class did race lose significance within our model.Conclusion:African Americans experience a greater amount of postoperative complications following surgery for Crohn’s disease. Preoperative disease management, addressing smoking status and control of comorbid disease are important factors in addressing the racial disparities in the surgical treatment of Crohn’s disease.

  • Accuracy of Faecal Calprotectin and Neutrophil Gelatinase B-associated
           Lipocalin in Evaluating Subclinical Inflammation in UlceRaTIVE
           Colitis—the ACERTIVE study
    • Authors: Magro F; Lopes S, Coelho R, et al.
      Abstract: Background and Aims:Mucosal healing and histological remission are different targets for patients with ulcerative colitis, but both rely on an invasive endoscopic procedure. This study aimed to assess faecal calprotectin and neutrophil gelatinase B–associated lipocalin as biomarkers for disease activity in asymptomatic ulcerative colitis patients.Methods:This was a multicentric cross-sectional study including 371 patients, who were classified according to their endoscopic and histological scores. These results were evaluated alongside the faecal levels of both biomarkers.Results:Macroscopic lesions [i.e. endoscopic Mayo score ≥1] were present in 28% of the patients, and 9% had active disease according to fht Ulcerative Colitis Endoscopic Index of Severity. Moreover, 21% presented with histological inflammation according to the Geboes index, whereas 15% and 5% presented with focal and diffuse basal plasmacytosis, respectively. The faecal levels of calprotectin and neutrophil gelatinase B–associated lipocalin were statistically higher for patients with endoscopic lesions and histological activity. A receiver operating characteristic–based analysis revealed that both biomarkers were able to indicate mucosal healing and histological remission with an acceptable probability, and cut-off levels of 150–250 μg/g for faecal calprotectin and 12 μg/g for neutrophil gelatinase B–associated lipocalin were proposed.Conclusions:Faecal calprotectin and neutrophil gelatinase B–associated lipocalin levels are a valuable addition for assessment of disease activity in asymptomatic ulcerative colitis patients. Biological levels of the analysed biomarkers below the proposed thresholds can rule out the presence of macroscopic and microscopic lesions with a probability of 75–93%. However, caution should be applied whenever interpreting positive results, as these biomarkers present consistently low positive predictive values.

  • Ano-genital Granulomatosis and Crohn’s Disease: A Case Series of Males
           Presenting with Genital Lymphoedema
    • Authors: Alexakis C; Gordon K, Mellor R, et al.
      Abstract: Background and Aims:Ano-genital granulomatosis is a rare chronic granulomatous condition of the skin that causes lymphoedema of the external genitalia. There is a reported association with Crohn’s disease. Mechanisms of disease and optimal methods of treatment are poorly understood.Methods:A retrospective casenote review of 25 male patients with ano-genital granulomatosis presenting with genital lymphoedema was performed to determine the clinical and histopathological features of this condition and its relationship to intestinal Crohn’s disease.Results:A combination of penile and scrotal oedema was reported at presentation in 80% of patients; 40% of patients had associated intestinal Crohn’s disease. The average time from symptom onset to diagnosis was 52.7 months. Half of cutaneous biopsies contained non-caseating granulomas and 14% contained intralymphatic granulomas. In all, 72% of patients responded to oral steroids initially but recurrence was common. Complete or partial response was achieved in 60% of patients treated with azathioprine. Three of six patients responded to anti-tumour necrosis factor [TNF] therapy. A small proportion of patients required circumcision or de-bulking surgery for more debilitating disease.Conclusions:Ano-genital granulomatosis is a rare condition that presents with genital lymphoedema, and there is frequently a protracted delay in diagnosis. There is a very strong association with intestinal Crohn’s disease. Genital lymphoedema associated with gastrointestinal symptoms should prompt careful evaluation to exclude both ano-genital granulomatosis and Crohn’s disease.

  • Cell-specific Activation of the Nrf2 Antioxidant Pathway Increases Mucosal
           Inflammation in Acute but Not in Chronic Colitis
    • Authors: Gerstgrasser A; Melhem H, Leonardi I, et al.
      Abstract: Background and Aims:The transcription factor Nrf2 is a major modulator of the cellular antioxidant response. Oxidative burst of infiltrating macrophages leads to a massive production of reactive oxygen species in inflamed tissue of inflammatory bowel disease patients. This oxidative burst contributes to tissue destruction and epithelial permeability, but it is also an essential part of the antibacterial defence. We therefore investigated the impact of the Nrf2 orchestrated antioxidant response in both acute and chronic intestinal inflammation.Methods:To study the role of Nrf2 overexpression in mucosal inflammation, we used transgenic mice conditionally expressing a constitutively active form of Nrf2 [caNrf2] either in epithelial cells or in the myeloid cell lineage. Acute colitis was induced by dextran sulphate sodium [DSS] in transgenic and control animals, and changes in gene expression were evaluated by genome-wide expression studies. Long-term effects of Nrf2 activation were studied in mice with an IL-10-/- background.Results:Expression of caNrf2 either in epithelial cells or myeloid cells resulted in aggravation of DSS-induced acute colitis. Aggravation of inflammation by caNrf2 was not observed in the IL-10-/- model of spontaneous chronic colitis, where even a trend towards reduced prolapse rate was observed.Conclusions:Our findings show that a well-balanced redox homeostasis is as important in epithelial cells as in myeloid cells during induction of colitis. Aggravation of acute DSS colitis in response to constitutive Nrf2 expression emphasises the importance of tight regulation of Nrf2 during the onset of intestinal inflammation.

  • A Randomised, Double-blind, Placebo-controlled Trial of Trichuris suis ova
           in Active Crohn’s Disease
    • Authors: Schölmerich J; Fellermann K, Seibold FW, et al.
      Abstract: Background and Aims:To investigate the efficacy and safety of three different dosages of embryonated, viable eggs of Trichuris suis [TSO] versus placebo for induction of remission in mildly-to-moderately active ileocolonic, uncomplicated Crohn’s disease [CD].Methods:Adults with active CD [n = 252] randomly received six fortnightly doses of 250, 2500, or 7500 TSO/15 ml suspension/day [TSO 250, TSO 2500, TSO 7500], or 15 ml placebo solution/day, in a double-blind fashion, with 4 weeks’ follow-up. Primary endpoint was the rate of clinical remission [Crohn’s Disease Activity Index [CDAI] < 150] at end of treatment, ie at Week 12 or withdrawal. Secondary endpoints included the course of clinical remission, rate of clinical response, change in CDAI, change in markers of inflammation, mucosal healing, and Physician’s Global Assessment.Results:Clinical remission at Week 12 occurred in 38.5%, 35.2%, and 47.2% of TSO 250, TSO 2500, and TSO 7500 patients, respectively, and in 42.9% of placebo recipients. TSO induced a dose-dependent immunological response. There was no response regarding laboratory markers of inflammation. Other secondary efficacy variables also showed no advantage of TSO over placebo for treatment of active CD. Administration of TSO did not result in any serious adverse drug reaction. Review of non-serious suspected adverse drug reactions following TSO did not reveal any safety concerns.Conclusions:Administration of 250–7500 TSO fortnightly over 12 weeks was safe and showed a dose-dependent immunological response, but no TSO dose showed a clinically relevant effect over placebo for induction of clinical remission or response in mildly-to-moderately active, ileocolonic CD.

  • Integrative Network-based Analysis of Colonic Detoxification Gene
           Expression in Ulcerative Colitis According to Smoking Status
    • Authors: Ding Y; Ladeiro Y, Morilla I, et al.
      Abstract: Backgrounds and Aims:The effect of cigarette smoking [CS] is ambivalent since smoking improves ulcerative colitis [UC] while it worsens Crohn’s disease [CD]. Although this clinical relationship between inflammatory bowel disease [IBD] and tobacco is well established, only a few experimental works have investigated the effect of smoking on the colonic barrier homeostasis focusing on xenobiotic detoxification genes.Methods:A comprehensive and integrated comparative analysis of the global xenobiotic detoxification capacity of the normal colonic mucosa of healthy smokers [n = 8] and non-smokers [n = 9] versus the non-affected colonic mucosa of UC patients [n = 19] was performed by quantitative real-time polymerase chain reaction [qRT PCR]. The detoxification gene expression profile was analysed in CD patients [n = 18], in smoking UC patients [n = 5], and in biopsies from non-smoking UC patients cultured or not with cigarette smoke extract [n = 8].Results:Of the 244 detoxification genes investigated, 65 were dysregulated in UC patients in comparison with healthy controls or CD patients. The expression of ≥ 45/65 genes was inversed by CS in biopsies of smoking UC patients in remission and in colonic explants of UC patients exposed to cigarette smoke extract. We devised a network-based data analysis approach for differentially assessing changes in genetic interactions, allowing identification of unexpected regulatory detoxification genes that may play a major role in the beneficial effect of smoking on UC.Conclusions:Non-inflamed colonic mucosa in UC is characterised by a specifically altered detoxification gene network, which is partially restored by tobacco. These mucosal signatures could be useful for developing new therapeutic strategies and biomarkers of drug response in UC.

  • Long-term Efficacy of Vedolizumab for Crohn’s Disease
    • Authors: Vermeire S; Loftus EV, Jr, Colombel J, et al.
      Abstract: Background and Aims:Vedolizumab is a gut-selective α4β7 integrin antagonist therapy for ulcerative colitis and Crohn’s disease. The GEMINI long-term safety [LTS] trial is an ongoing open-label study investigating the safety of vedolizumab. We present interim exploratory analyses of efficacy in patients with Crohn’s disease.Methods:Patients from the C13004, GEMINI 2 and GEMINI 3 studies and vedolizumab-naïve patients could enrol in GEMINI LTS and received vedolizumab every 4 weeks. Data were collected from May 22, 2009 to June 27, 2013. Outcomes of clinical response and remission, defined by the Harvey-Bradshaw Index, and health-related quality of life [HRQL] were assessed for up to 152 weeks of treatment in the efficacy population.Results:Among patients with response at week 6 in GEMINI 2 who received vedolizumab continuously, 83% [n=100/120] and 89% [n=62/70] of patients with available data were in remission after 104 and 152 weeks, respectively. Increased dosing frequency from every 8 weeks [GEMINI 2] to every 4 weeks [GEMINI LTS] improved outcomes in patients who had withdrawn early from GEMINI 2, with 47% [n=27/57] experiencing clinical response and 32% [n=18/57] in remission at week 52 of GEMINI LTS [up from 39% and 4% before the dose increase]. Similar improvements were observed regardless of prior tumour necrosis factor [TNF] antagonist exposure. Long-term benefits of HRQL were also observed.Conclusions:The clinical benefits of vedolizumab continued with long-term treatment regardless of prior TNF antagonist exposure. Increased dosing frequency might improve outcomes in patients who lose response to conventional 8-weekly dosing.

  • Development and Validation of Risk Matrices for Crohn’s Disease Outcomes
           in Patients Who Underwent Early Therapeutic Interventions
    • Authors: Dias C; Rodrigues P, Coelho R, et al.
      Abstract: Introduction:The establishment of prognostic models for Crohn’s disease [CD] is highly desirable, as they have the potential to guide physicians in the decision-making process concerning therapeutic choices, thus improving patients’ health and quality of life. Our aim was to derive models for disabling CD and reoperation based solely on clinical/demographic data.Methods:A multicentric and retrospectively enrolled cohort of CD patients, subject to early surgery or immunosuppression, was analysed in order to build Bayesian network models and risk matrices. The final results were validated internally and with a multicentric and prospectively enrolled cohort.Results:The derivation cohort included a total of 489 CD patients [64% with disabling disease and 18% who needed reoperation], while the validation cohort included 129 CD patients with similar outcome proportions. The Bayesian models achieved an area under the curve of 78% for disabling disease and 86% for reoperation. Age at diagnosis, perianal disease, disease aggressiveness and early therapeutic decisions were found to be significant factors, and were used to construct user-friendly matrices depicting the probability of each outcome in patients with various combinations of these factors. The matrices exhibit good performance for the most important criteria: disabling disease positive post-test odds = 8.00 [2.72–23.44] and reoperation negative post-test odds = 0.02 [0.00–0.11].Conclusions:Clinical and demographical risk factors for disabling CD and reoperation were determined and their impact was quantified by means of risk matrices, which are applicable as bedside clinical tools that can help physicians during therapeutic decisions in early disease management.

  • Fluoxetine for Maintenance of Remission and to Improve Quality of Life in
           Patients with Crohn’s Disease: a Pilot Randomized Placebo-Controlled
           Trial
    • Authors: Mikocka-Walus A; Hughes PA, Bampton P, et al.
      Abstract: Background and Aims:Previous studies have shown that antidepressants reduce inflammation in animal models of colitis. The present trial aimed to examine whether fluoxetine added to standard therapy for Crohn’s disease [CD] maintained remission, improved quality of life [QoL] and/or mental health in people with CD as compared to placebo.Methods:A parallel randomized double-blind placebo controlled trial was conducted. Participants with clinically established CD, with quiescent or only mild disease, were randomly assigned to receive either fluoxetine 20 mg daily or placebo, and followed for 12 months. Participants provided blood and stool samples and completed mental health and QoL questionnaires. Immune functions were assessed by stimulated cytokine secretion [CD3/CD28 stimulation] and flow cytometry for cell type. Linear mixed-effects models were used to compare groups.Results:Of the 26 participants, 14 were randomized to receive fluoxetine and 12 to placebo. Overall, 14 [54%] participants were male. The mean age was 37.4 [SD=13.2] years. Fluoxetine had no effect on inflammatory bowel disease activity measured using either the Crohn’s Disease Activity Index [F(3, 27.5)=0.064, p=0.978] or faecal calprotectin [F(3, 32.5)=1.08, p=0.371], but did have modest effects on immune function. There was no effect of fluoxetine on physical, psychological, social or environmental QoL, anxiety or depressive symptoms as compared to placebo [all p>0.05].Conclusions:In this small pilot clinical trial, fluoxetine was not superior to placebo in maintaining remission or improving QoL.

  • The Complexity of alpha E beta 7 Blockade in Inflammatory Bowel Diseases
    • Authors: Smids C; Horjus Talabur Horje CS, van Wijk F, et al.
      Abstract: Monoclonal antibodies targeting integrins are emerging as new treatment option in inflammatory bowel diseases. Integrins are molecules involved in cell adhesion and signalling. After the successful introduction of anti-α4β7, currently anti-β7 is under evaluation in a phase three trial. Anti-β7 blocks both α4β7/MAdCAM-1 and αEβ7/E-cadherin interaction, targeting both the homing to and the retention in the gut of potential pathological T cells. Since the physiological and potential pathological roles of immune cells expressing αEβ7 are less distinct than of those expressing α4β7, an overview of the current state of knowledge on αEβ7 in mice and humans in both health and inflammatory bowel diseases is presented here, also addressing the potential consequences of anti-β7 treatment.
