  • Budesonide MMX Add-on to 5-Aminosalicylic Acid Therapy in Mild-to-Moderate
           Ulcerative Colitis: A Favourable Risk-Benefit Profile
    • Authors: Danese S; Bonovas , Peyrin-Biroulet L.
      First page: 767
      Abstract: Current clinical practice guidelines recommend 5-aminosalicylic acids [5-ASA] as first-line therapy for induction and maintainance of remission in active, mild-to-moderate ulcerative colitis [UC].1,2 Systemic corticosteroids are prescribed when symptoms of active colitis do not respond to 5-ASA.1,2 However, the high frequency of adverse effects that are associated with short- and long-term use of systemic corticosteroids, including ocular, dermatological, metabolic, gastrointestinal, musculoskeletal, and central nervous system effects, as well as hypertension, hypothalamic-pituitary-adrenal axis suppression, and infections,3 prompted the development of a new generation of less toxic steroid compounds, such as budesonide. These are characterised by high topical anti-inflammatory activity and low systemic bioavailability aimed at minimising the amount of drug that reaches the systemic circulation.4,5

  • Budesonide Multimatrix Is Efficacious for Mesalamine-refractory, Mild to
           Moderate Ulcerative Colitis: A Randomised, Placebo-controlled Trial
    • Authors: Rubin DT; Cohen RD, Sandborn WJ, et al.
      First page: 785
      Abstract: AbstractBackground and Aims:Safety and efficacy of budesonide multimatrix, an oral extended-release second-generation corticosteroid designed for targeted delivery throughout the colon, were examined for induction of remission in patients with mild to moderate ulcerative colitis refractory to baseline mesalamine therapy.Methods:A randomised, double-blind, placebo-controlled, multicentre trial evaluated efficacy and safety of budesonide multimatrix for induction of remission [ulcerative colitis disease activity index score ≥ 4 and ≤ 10] in 510 adults randomised to once-daily oral budesonide multimatrix 9 mg or placebo for 8 weeks. Patients continued baseline treatment with oral mesalamine ≥ 2.4 g/day.Results:Combined clinical and endoscopic remission at Week 8 was achieved by 13.0% and 7.5% of patients receiving budesonide multimatrix [n = 230] or placebo [n = 228], respectively, in the modified intention-to-treat population [p = 0.049]. Clinical remission [ulcerative colitis disease activity index rectal bleeding and stool frequency subscale scores of 0] was similar in both groups [p = 0.70]. More patients receiving budesonide multimatrix vs placebo achieved endoscopic remission [ulcerative colitis disease activity index mucosal appearance subscale score of 0; 20.0% vs 12.3%; p = 0.02] and histological healing [27.0% vs 17.5%; p = 0.02]. Adverse event rates were similar [budesonide multimatrix, 31.8%; placebo, 27.1%]. Mean morning cortisol concentrations decreased at Weeks 2, 4, and 8 with budesonide multimatrix but remained within the normal range.Conclusion:Budesonide multimatrix was safe and efficacious for inducing clinical and endoscopic remission for mild to moderate ulcerative colitis refractory to oral mesalamine therapy.

  • Early Tuberculin Skin Test for the Diagnosis of Latent Tuberculosis
           Infection in Patients with Inflammatory Bowel Disease
    • Authors: Taxonera C; Ponferrada Á, Bermejo F, et al.
      First page: 792
      Abstract: AbstractBackground and Aim:Sensitivity of tuberculin skin test [TST] during screening for latent tuberculosis infection [LTBI] is affected by steroid and/or immunosuppressant therapy. The aim of this study was to compare performance of the two-step TST in inflammatory bowel disease patients immediately before anti-tumour necrosis factor [TNF] therapy as part of routine screening for LTBI vs control patients when the TST was carried out at an early stage.Methods:In this multicentre prospective controlled study, we evaluated the performance of two-step TST with 5-mm threshold. Factors associated with TST results were determined by logistic regression.Results:We evaluated 243 candidates for anti-TNF therapy and 337 control patients. Overall, 105 patients [18.1%] had an induration ≥ 5 mm in the first TST or in TST retest. LTBI was diagnosed in 25% of patients by TST retest. Twenty-eight [11.5%] anti-TNF group patients vs 77 [22.8%] control patients had a positive TST (odds ratio [OR] 0.44, 95% confidence interval [CI] 0.28–0.70; P < 0.001]. In multivariate analysis, positive TST was associated with higher age [OR 2.63, 95% CI 1.21–5.72; P < 0.001] and 5-aminosalicylate therapy [OR 1.86, 95% CI 1.14–3.05; P = 0.013]. Negative TST was associated with steroid therapy [OR 0.36, 95% CI 0.16–0.83; P = 0.016], immunosuppressant therapy [OR 0.36, 95% CI 0.21–0.62; P < 0.001], or steroids + immunosuppressant therapy [OR 0.20, 95% CI 0.07–0.59; P = 0.004].Conclusions:The sensitivity of routine TST performed just before starting anti-TNF therapy is low. TST performed at an early stage enables screening in the absence of immunosuppressive treatment and thus maximises the diagnostic yield of TST for detecting LTBI.

  • Machine Learning Algorithms for Objective Remission and Clinical Outcomes
           with Thiopurines
    • Authors: Waljee AK; Sauder K, Patel A, et al.
      First page: 801
      Abstract: AbstractBackground and Aims:Big data analytics leverage patterns in data to harvest valuable information, but are rarely implemented in clinical care. Optimising thiopurine therapy for inflammatory bowel disease [IBD] has proved difficult. Current methods using 6-thioguanine nucleotide [6-TGN] metabolites have failed in randomized controlled trials [RCTs], and have not been used to predict objective remission [OR]. Our aims were to: 1) develop machine learning algorithms [MLA] using laboratory values and age to identify patients in objective remission on thiopurines; and 2) determine whether achieving algorithm-predicted objective remission resulted in fewer clinical events per year.Methods:Objective remission was defined as the absence of objective evidence of intestinal inflammation. MLAs were developed to predict three outcomes: objective remission, non-adherence, and preferential shunting to 6-methylmercaptopurine [6-MMP]. The performance of the algorithms was evaluated using the area under the receiver operating characteristic curve [AuROC]. Clinical event rates of new steroid prescriptions, hospitalisations, and abdominal surgeries were measured.Results:Retrospective review was performed on medical records of 1080 IBD patients on thiopurines. The AuROC for algorithm-predicted remission in the validation set was 0.79 vs 0.49 for 6-TGN. The mean number of clinical events per year in patients with sustained algorithm-predicted remission [APR] was 1.08 vs 3.95 in those that did not have sustained APR [p < 1 x 10-5]. Reductions in the individual endpoints of steroid prescriptions/year [-1.63, p < 1 x 10-5], hospitalisations/year [-1.05, p < 1 x 10-5], and surgeries/year [-0.19, p = 0.065] were seen with algorithm-predicted remission.Conclusions:A machine learning algorithm was able to identify IBD patients on thiopurines with algorithm-predicted objective remission, a state associated with significant clinical benefits, including decreased steroid prescriptions, hospitalisations, and surgeries.

  • Eldelumab [anti-interferon-γ-inducible protein-10 antibody] Induction
           Therapy for Active Crohn’s Disease: a Randomised, Double-blind,
           Placebo-controlled Phase IIa Study
    • Authors: Sandborn WJ; Rutgeerts P, Colombel J, et al.
      First page: 811
      Abstract: AbstractBackground and Aims:This 11-week Phase IIa induction study evaluated the efficacy and safety of eldelumab in patients with active Crohn’s disease.Methods:Adults with Crohn’s Disease Activity Index 220–450 were randomised 1:1:1 to placebo or eldelumab 10 or 20 mg/kg intravenously on Days 1 and 8, and alternate weeks thereafter. All patients underwent ileocolonoscopy at baseline. Patients with active inflammation according to the Simplified Endoscopic Score for Crohn’s Disease criteria [the originally planned endoscopy cohort] underwent another ileocolonoscopy at Week 11 at the investigator’s discretion. All ileocolonoscopies were centrally read. The primary objective was identification of the eldelumab target exposure for induction of remission [absolute Crohn’s Disease Activity Index score < 150]. Rates of clinical response [reduction of ≥ 100 from baseline or absolute score < 150 Crohn’s Disease Activity Index], remission, and endoscopic improvements were also assessed.Results:A total of 121 patients were randomised. The eldelumab exposure–remission relationship was not significant at Week 11. Numerically higher remission and response rates were reported with eldelumab 20 mg/kg [29.3% and 41.5%, respectively] and 10 mg/kg [22.5% and 47.5%] versus placebo [20.0% and 35.0%]. A higher proportion of patients with a baseline Simplified Endoscopic Score for Crohn’s Disease > 2 who received eldelumab achieved a 50% improvement in score and greater reductions from baseline endoscopy scores overall versus placebo. Adverse events were comparable across treatment groups.Conclusions:No exposure–remission relationship was seen with eldelumab. Eldelumab induction treatment demonstrated trends towards clinical and endoscopic efficacy. Safety was consistent with that reported identifier: NCT01466374.

  • X Chromosome-wide Association Study Identifies a Susceptibility Locus for
           Inflammatory Bowel Disease in Koreans
    • Authors: Lee H; Oh H, Yang S, et al.
      First page: 820
      Abstract: AbstractBackground and Aims:Genome-wide association studies of inflammatory bowel disease identified > 200 susceptibility loci only in autosomes. This study aimed to identify inflammatory bowel disease susceptibility loci on the X chromosome.Methods:We performed an X chromosome-wide association study in Korean patients with inflammatory bowel disease. We analysed X chromosome data from our recent genome-wide association studies, including 1505 cases [922 Crohn’s disease and 583 ulcerative colitis] and 4041 controls during the discovery phase, followed by replication in additional 1989 cases [993 Crohn’s disease, 996 ulcerative colitis] and 3491 controls. Sex-related differential effects of single nucleotide polymorphisms on disease were also evaluated.Results:We confirmed a significant association of a previously reported inflammatory bowel disease susceptibility locus at chromosome Xq26.3 [CD40LG-ARHGEF6; odds ratio, 1.22; 95% confidence interval, 1.16–1.28; combined p = 3.79 × 10−15]. This locus accounted for 0.18% and 0.12% of genetic variance in Crohn’s disease and ulcerative colitis, respectively, and increased the total autosomal chromosome genetic variance from 6.65% to 6.83% and from 5.47% to 5.59% for Crohn’s disease and ulcerative colitis risk, respectively, in the Korean population. Sex-stratified analyses did not reveal sex-related differences in effect sizes.Conclusions:We confirmed the association of rs2427870 at the CD40LG-ARHGEF6 locus with an inflammatory bowel disease through an X chromosome-wide association study in a Korean population. Our data suggest that the CD40LG-ARHGEF6 locus on the X chromosome might play a role in inflammatory bowel disease pathogenesis in the Korean population.

  • Profoundly Expanded T-cell Clones in the Inflamed and Uninflamed Intestine
           of Patients With Crohn’s Disease
    • Authors: Doorenspleet ME; Westera LL, Peters CP, et al.
      First page: 831
      Abstract: AbstractBackground and Aim:T cells are key players in the chronic intestinal inflammation that characterises Crohn’s disease. Here we aim to map the intestinal T-cell receptor [TCR] repertoire in patients with Crohn’s disease, using next-generation sequencing technology to examine the clonality of the T-cell compartment in relation to mucosal inflammation and response to therapy.Methods:Biopsies were taken from endoscopically inflamed and uninflamed ileum and colon of 19 patients with Crohn’s disease. From this cohort, additional biopsies were taken after 8 weeks of remission induction therapy from eight responders and eight non-responders. Control biopsies from 11 patients without inflammatory bowel disease [IBD] were included. The TCRβ repertoire was analysed by next-generation sequencing of biopsy RNA.Results:Both in Crohn’s disease patients and in non-IBD controls, a broad intestinal T-cell repertoire was found, with a considerable part consisting of expanded clones. Clones in Crohn’s disease were more expanded [p = 0.008], with the largest clones representing up to as much as 58% of the total repertoire. There was a substantial overlap of the repertoire between inflamed and uninflamed tissue and between ileum and colon. Following therapy, responders showed larger changes in the T-cell repertoire than non-responders, although a considerable part of the repertoire remained unchanged in both groups.Conclusions:The intestinal T-cell repertoire distribution in Crohn’s disease is different from that in the normal gut, containing profoundly expanded T-cell clones that take up a large part of the repertoire. The T-cell repertoire is fairly stable regardless of endoscopic mucosal inflammation or response to therapy.

  • Bacteriophages Targeting Adherent Invasive Escherichia coli Strains as a
           Promising New Treatment for Crohn’s Disease
    • Authors: Galtier M; Sordi L, Sivignon A, et al.
      First page: 840
      Abstract: AbstractBackground and Aims:Adherent invasive Escherichia coli [AIEC] are abnormally predominant on the ileal mucosa of Crohn’s disease [CD] patients. They bind to the CEACAM6 receptor expressed on the surface of epithelial cells. We aimed to assess the potential of bacteriophages, viruses infecting bacteria, to decrease the levels of AIEC bacteria associated with the intestinal mucosa.Methods:We combined ex vivo and in vivo experiments with murine and human intestinal samples to quantify the ability of virulent bacteriophages to target the prototype AIEC strain LF82.Results:We found that three virulent bacteriophages were able to replicate in ileal, caecal and colonic sections and faeces homogenates from murine gut samples colonised with the prototype AIEC strain LF82. A single day of per os treatment with the three bacteriophages cocktail given to LF82-colonised CEABAC10 transgenic mice, expressing the human CEACAM6 receptor for AIEC, decreased significantly the number of AIEC in faeces and in the adherent flora of intestinal sections. In addition, a single dose of the cocktail reduced dextran sodium sulphate-induced colitis symptoms on conventional mice colonised with the strain LF82 over a 2-week period. The cocktail targeted also LF82 bacteria in homogenates of ileal biopsies taken from CD patients.Conclusions:These findings demonstrate that bacteriophages are a new treatment option for targeting AIEC in CD patients and represent a strong basis for a clinical trial evaluation.

  • Identification of Antibody Against SNRPB, Small Nuclear

           Marker in Crohn’s Disease using an Immunoproteomics Approach
    • Authors: Wang H; Demirkan G, Bian X, et al.
      First page: 848
      Abstract: AbstractBackground:Current non-invasive biomarkers for Crohn’s disease are limited in their utility. Progress in identifying individual autoantigens and autoantibodies in Crohn’s disease has been challenging due to limitations of available immunoassays.Aims:Our aim was to identify autoantibodies associated with Crohn’s disease that may be useful in diagnosis and management using an innovative protein array technology, namely nucleic acid programmable protein arrays [NAPPA].Methods:Serum samples of 96 patients with established Crohn’s disease and 96 healthy controls were included and evenly split into discovery and validation sets randomly. Autoantibodies of both IgG and IgA classes were profiled against ~1900 human proteins in the discovery set on NAPPA. Autoantibodies discovered to be Crohn’s disease-specific were further validated in the independent validation set by enzyme-linked immunosorbent assay.Results:Overall, reactivity of IgG autoantibodies was stronger than that of IgA autoantibodies; however, IgA autoantibodies showed greater differential reactivity between cases and controls. Four IgA autoantibodies against SNRPB, PRPH, PTTG1 and SNAI1 were newly identified with sensitivities above 15% at 95% specificity, among which anti-SNRPB-IgA had the highest sensitivity of 24.0%. Autoantibodies associated with specific disease subtypes were also found.Conclusions:As one of the first studies to use immunoproteomics for the identification of autoantibodies in Crohn’s disease, our results support the utility of NAPPA in implementing future expanded studies with better coverage of the human proteome and microbial proteomes relevant to Crohn’s disease and identifying antibody markers that may have clinical impact in diagnosis and management.

  • Prdx6 Deficiency Ameliorates DSS Colitis: Relevance of Compensatory
           Antioxidant Mechanisms
    • Authors: Melhem H; Spalinger MR, Cosin-Roger J, et al.
      First page: 871
      Abstract: AbstractBackground and Aims:An imbalance between cellular antioxidant defence system[s] and reactive oxygen species [ROS]-driven oxidative stress has been implicated in the pathogenesis of inflammatory bowel disease. Peroxiredoxin [PRDX] 6 contributes to an appropriate redox balance by clearing ROS and reducing peroxidized membrane phospholipids. We here studied the role of PRDX6 in acute and chronic dextran sodium sulphate [DSS]-induced colitis.Methods:To investigate the impact of PRDX6 on intestinal inflammation, we used wild type [WT], Prdx6 knock-out mice [Prdx6-/-] and transgenic mice [Prdx6tg/tg], overexpressing Prdx6. Acute and chronic colitis was induced by DSS in WT, Prdx6-/- and Prdx6tg/tg mice. Colitis was evaluated by endoscopy, colon length, histopathological assessment and myeloperoxidase [MPO] activity. Changes in mRNA and protein expression of pro-inflammatory cytokines and antioxidant enzymes were evaluated by real-time quantitative polymerase chain reaction [RT-qPCR] and western blot. Total glutathione [GSH] levels in colon samples were determined.Results:Prdx6-/- mice exposed to acute and chronic DSS showed a significant decrease in the clinical parameters and in colonic expression of pro-inflammatory cytokines compared with WT mice. mRNA expression of antioxidant enzymes in colon samples was significantly increased in Prdx6-/- compared with WT mice exposed to acute and chronic DSS. In addition, total GSH levels were increased in Prdx6-/- mice treated with DSS in comparison with WT. Overexpression of Prdx6 did not significantly influence acute and chronic colitis.Conclusions:Our data indicate that a lack of the antioxidant enzyme PRDX6 protects against the development of acute and chronic experimental colitis and is associated with increased expression and function of other antioxidant enzymes, suggesting effective compensatory mechanisms.

  • The Future of Janus Kinase Inhibitors in Inflammatory Bowel Disease
    • Authors: De Vries LS; Wildenberg ME, De Jonge WJ, et al.
      First page: 885
      Abstract: AbstractInflammatory bowel diseases, such as ulcerative colitis and Crohn’s disease, are disabling conditions characterised by chronic, relapsing inflammation of the gastrointestinal tract. Current treatments are not universally effective or, in the case of therapeutic antibodies, are hampered by immune responses. Janus kinase inhibitors are orally delivered small molecules that target cytokine signalling by preventing phosphorylation of Janus kinases associated with the cytokine receptor. Subsequently, phosphorylation of signal transducers and activators of transcription that relay Janus kinase signalling and transcription of cytokines in the nucleus will be diminished. Key cytokines in the pathogenesis of inflammatory bowel diseases are targeted by Janus kinase inhibitors. Several Janus kinase inhibitors are in development for the treatment of inflammatory bowel diseases. Tofacitinib, inhibiting signalling via all Janus kinase family members, was effective in phase 2 and 3 trials in moderate-severe ulcerative colitis. GSK2586184, a Janus kinase 1 selective inhibitor, induced clinical and endoscopic response in ulcerative colitis; however, the study was discontinued at an early stage due to liver toxicity observed in systemic lupus patients receiving the drug. Filgotinib, a Janus kinase 1 selective inhibitor investigated in treatment of Crohn’s disease, was superior to placebo. As adverse events associated with the broad immunological effect of these agents have been reported, the future application of these drugs is potentially limited. We will discuss the treatment efficacy of Janus kinase inhibition in inflammatory bowel diseases, how current Janus kinase inhibitors available target immune responses relevant in inflammatory bowel disease, and whether more specific kinase inhibition could be effective.

  • Completion Proctectomy for Crohn’s Colitis: Lessons Learned
    • Authors: Mihes Y; Hogan NM, Egan L, et al.
      First page: 894
      Abstract: AbstractSurgical management of Crohn’s disease is reserved for patients refractory to medical therapy and those who develop complications alleviated by surgery. Surgical resection may be the most efficient way to restore health in patients with stricturing and or fistulizing disease of the terminal ileum / small bowel. However, decision-making in patients with Crohn’s colitis is more difficult. The merits of segmental resection versus subtotal/total colectomy versus total proctocolectomy with end ileostomy are affected by a myriad of factors, including extent of colon involvement, the patient’s age, and the patient’s degree of desire to avoid an ileostomy. In patients undergoing a total proctocolectomy for Crohn’s colitis, the anal canal should be removed. The following case highlights the potential difficulty that may arise when the anal canal is left in situ.

      Abstract: We read with interest the article by Antonina Mikocka-Walus et al., examining whether fluoxetine added to standard therapy for Crohn’s disease [CD] maintained remission, and/or improved quality of life [QoL] and/or mental health in people with CD as compared with placebo.1 The authors found that fluoxetine was not superior to placebo in maintaining remission or improving QoL. Because their findings are important to both current practice and future research, several questions deserve attention.

  • Tissue Non-specific Alkaline Phosphatase Expression is Needed for the Full
           Stimulation of T Cells and T Cell-Dependent Colitis
    • Authors: Hernández-Chirlaque C; Gámez-Belmonte R, Ocón B, et al.
      First page: 857
      Abstract: AbstractBackground and Aims:Two alkaline phosphatase isoforms, intestinal [IAP] and tissue non-specific alkaline phosphatase [TNAP], are coexpressed in mouse colon, with the latter predominating in colitis. We aimed to examine the role of TNAP in T lymphocytes, using heterozygous TNAP+/- mice [as TNAP-/- mice are non-viable].Methods:In vitro primary cultures and in vivo T cell models using TNAP+/- mice were used.Results:Stimulated splenocytes [lipopolysaccharide and concanavalin A] and T lymphocytes [concanavalin A and a-CD3/a-CD28] showed a decreased cytokine production and expression when compared with wild-type [WT] cells. Decreased T cell activation was reproduced by the TNAP inhibitors levamisole, theophylline, and phenylalanine in WT cells. Intraperitoneal administration of anti-CD3 in vivo resulted in reduced plasma cytokine levels, and decreased activation of splenocytes and T cells ex vivo in TNAP+/- mice. We further tested the hypothesis that TNAP expressed in T lymphocytes is involved in T cell activation and inflammation, using the lymphocyte transfer model of colitis. Rag1-/- mice were transferred with T naïve cells [CD4+ CD62L+] from TNAP+/- or WT mice and developed colitis, which was attenuated in the group receiving TNAP+/- cells. Compared with WT, T cells from TNAP+/- mice showed a decreased capacity for proliferation, with no change in differentiation.Conclusions:Our results offer clear evidence that TNAP modulates T lymphocyte function and specifically T cell-dependent colitis. This was associated with distinct changes in the type of TNAP expressed, probably because of changes in glycosylation.
