Abstract Background Observational data in children and RCT data in adults indicate that methotrexate (MTX) is associated with induction and maintenance of clinical remission in luminal Crohn’s disease, but efficacy in achieving intestinal healing has not been examined. Aims To examine the evolution of MRE signs of inflammation in children treated with MTX. Methods In this retrospective cohort study, we reviewed paediatric CD patients on maintenance MTX monotherapy for >4 months who underwent serial MREs between July 2010 and October 2015. MREs were reviewed by a radiologist blind to clinical data. Overall inflammatory activity on each MRE was scored as minimal, mild, moderate or severe, informed by the presence of bowel wall thickness, wall enhancement, T2 hyperintensity, comb sign, mesenteric edema, penetrating disease, stricturing, diffusion restriction and motility. The radiologist’s global assessment of change from MRE 1 to MRE 2 was scored as improved, unchanged or worsened. Clinical findings, disease activity (assessed by weighted paediatric CD activity index [wPCDAI]) and surgical history were also extracted from medical records by a clinician blind to MRE results. Results Thirty-five patients were included (median age at diagnosis 12 [IQR 11–14] years; 77% male; 60% inflammatory (B1), 17% stricturing (B2), 23% penetrating (B3) disease). Between baseline and follow-up MRE, wPCDAI (median 15 [IQR 7–43] decreased to 8 [IQR 0–18]; p=0.006) and CRP (median 9 [IQR 2–36] decreased to 5 [IQR 5–9]; p=0.013) and 74% (N=26) were in clinical remission (wPCDAI < 12.5) at MRE 2. MRE features that significantly improved from MRE 1 to 2 were comb sign from 63% (N=37) to 38% (N=14) (p=0.02) and penetrating disease from 14% (N=8) to 0 (p=0.03). After a median of 17 months (IQR 13–23), 51% (N=18) of patients improved, 29% (N=10) worsened and 20% (N=7) had no change based on the radiologist’s global assessment. Of the 21 patients with moderate/severe disease at MRE 1, 33% (N=7) had minimal/mild disease by MRE 2. 66% (N=14/21) continued to have moderate/severe disease at MRE 2. Additionally, a further 14% (N=2/14) of those with minimal/mild disease at baseline MRE progressed to moderate/severe disease at MRE 2. Complete details of change between MRE 1 and MRE 2 are displayed in Figure 1. Conclusions Despite signs of clinical improvement, many paediatric CD patients on maintenance MTX therapy for >4 months have unchanged or worsened MRE findings. This underscores the need for follow-up imaging in these cases. Funding Agencies None

Abstract Background The α4β7 integrin monoclonal antibody vedolizumab (VDZ) has been shown to be efficacious for patients with moderate-to-severe Crohn’s disease (CD). This study aimed to analyse the added value of budesonide in combination with VDZ as an induction treatment for this indication. Methods A multicentre, retrospective chart review study was conducted in Belgium, Israel, and Switzerland. Adult patients with moderately to severely active CD (defined as an abdominal pain [AP] score of ≥2 and/or a mean daily loose stool frequency [LSF] score of ≥4 for the previous 7 days) who initiated induction therapy with either VDZ monotherapy (mono) or a combination therapy (combo) of VDZ with budesonide (index date) between 1 January 2015 and 31 January 2019 were included. Patients who received VDZ by IV infusion at weeks 0, 2, 6, 10 (only some patients received VDZ during week 10), and 8 weeks thereafter were assessed for time to patient-reported outcome (PRO) clinical remission (Kaplan-Meier curves), defined as an average daily composite score of AP ≤1 and LSF ≤31 within 14 weeks. Regression models were used to assess differences and associations. Results Overall, 123 patients were included (mono, n=73; combo, n=50). Patients initiating combo presented with more severe disease at index date than patients initiating mono. PRO clinical remission rates were estimated at 71.4% (50/70) in the mono and 68.0% (34/50) in the combo groups, with a similar median time to PRO remission of 91 days (95% CI: 70–98) and 95 days (95% CI: 70–98), respectively (Figure 1). Figure 2 shows the mean % change in AP and LSF from baseline to week 14, which was comparable for mono and combo. The variables associated with mean % change were moderate and severe AP scores for AP and being a current smoker for LSF. One patient in each group discontinued VDZ before week 14 (due to lack of effectiveness [mono] and adverse event [AE; combo]); 68.0% of patients in the combo group discontinued budesonide by the end of the follow up period. The reasons for discontinuation were routine treatment regimen (8 weeks 9 mg/day+subsequent tapering-off) in 85.3% of the patients, lack of effectiveness in 5.9% and AEs in 2.9% (5.8% other reasons). Safety event rates were similar among the groups for overall AEs (mono, 23.3%; combo, 26.0%), with the majority designated as mild to moderate in severity, and 83.3% resolved within the follow-up period. Conclusion Comparable effectiveness and safety outcomes were observed with mono and combo therapy in patients with CD; however, disease state among patients receiving combo was more refractory/severe at baseline. Further evidence is needed to corroborate these findings. Reference

Ileal Stricture

Abstract Background Stricturing Crohn’s disease (CD) constitutes a severe phenotype often associated with a high degree of morbidity (3). Surgical resection is first-line therapy for symptomatic strictures, but most patients relapse without subsequent medical therapy (4–5). Biologics are the mainstay for inducing and maintaining remission, but some cases are refractory despite maximum dosage of therapy. Reports of dual biological therapy (DBT) in refractory, stricturing CD are sparse, and prior case reports document only clinical remission (1). To contribute further knowledge regarding the use of DBT in stricturing CD, we present the case of a refractory CD patient who achieved deep remission with ustekinumab and vedolizumab. Case Presentation A 35 year old non-smoking, Caucasian male was referred to our clinic in 2014 for refractory CD complicated by multiple strictures. Prior to establishing care with us, he received two jejunal resections and a sigmoid resection. Previously failed therapies included azathioprine with infliximab, adalimumab, and certolizumab. He continued to progress under our care despite combination methotrexate/certolizumab, as well as methotrexate/golimumab. He underwent proctocolectomy with end ileostomy in 2015 and initiated vedolizumab q8weeks post-operatively. He reoccurred in 2018, when he presented with an ulcerated ileal stricture. He was switched from vedolizumab to ustekinumab q8weeks and placed on prednisone, but continued to progress, developing significant hematochezia requiring hospitalization and blood transfusions. Ileoscopy performed during hospital admission confirmed severe, ulcerating disease in the ileum with stricture. Ustekinumab dosing was increased to q4weeks, azathioprine was initiated, and he underwent stricturoplasty. Follow-up ileoscopy three months later revealed two ulcers in the neo- TI (Figure 1). Vedolizumab q8weeks was initiated in addition to ustekinumab q4weeks and azathioprine 125mg. After four months on this regimen the patient felt better, but follow-up ileoscopy showed two persistent ulcers in the neo-TI. Vedolizumab dosing interval was increased to q4weeks. After four months, subsequent ileoscopy demonstrated normal neo-TI (Figure 2). Histologic evaluation of biopsies confirmed deep remission of crohn’s disease. No adverse side effects have occurred with maximum doses of both ustekinumab and vedolizumab combination therapy. Discussion This case supports both the safety and efficacy of ustekinumab and vedolizumab dual biologic therapy for treatment of severe, refractory Crohn’s disease. While there are reports of DBT inducing clinical remission, this case supports efficacy for vedolizumab and ustekinumab combination therapy to induce deep histologic remission. Large practical clinical trials are needed to better investigate the safety and efficacy of DBT with vedolizumab and ustekinumab, but our case suggests this combination may be a safe and efficacious therapy for refractory CD patients.

Abstract Background Vedolizumab (VDZ) is an effective treatment for Crohn’s disease (CD); however, inadequate and loss of response is common. Pivotal VDZ trials evaluated alternative dosing intervals, demonstrating numeric but not statistical superiority in efficacy as compared to FDA-approved dosing. The safety and effectiveness of FDA-approved and modified-dosing schedules in a real-world population are unknown. We aimed to evaluate clinical and endoscopic effectiveness & safety of standard and modified maintenance VDZ dosing in a real world cohort. Methods We retrospectively reviewed CD patients (pts) treated with >3 months VDZ, assessing Harvey Bradshaw Index (HBI), Simple Endoscopic Score for Crohn’s disease (SESCD), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), C-reactive protein (CRP), albumin and hematocrit prior to and following standard VDZ dosing, and prior to and following modified VDZ maintenance dosing. We measured duration on therapy and adverse events. Results We identified 226 eligible pts, mean age 41.5 years, 55.3% female, median disease duration 10 years, 88.9% with prior biologic exposure. Mean duration on VDZ was 28.3 months. Standard VDZ dosing: 61.5% of pts with active clinical disease and adequate follow up data achieved clinical response after 3–12 months; 41.0% had clinical remission. 51.9% of pts with active endoscopic disease and adequate follow up data achieved mucosal improvement; 42.3% had endoscopic remission; 26.0% had mucosal healing after 3–24 months. 50.0% of pts with elevated CRP and adequate follow up data normalized CRP after 3–12 months. Modified maintenance dosing: 72 non-remitters to standard VDZ dosing received modified VDZ maintenance dosing. 51.5% of pts with active clinical disease prior to starting dose modification and adequate follow up data achieved clinical response after 3–12 months of modified maintenance dosing; 42.4% had clinical remission. 22.2% of pts with SESCD ≥3 prior to starting dose modification achieved mucosal improvement after 3–24 months; 22.2% had mucosal healing. 26.7% of pts with SESCD ≥4 prior to starting modified dosing had endoscopic remission after 3–24 months. 50.0% of pts with elevated CRP and adequate follow up data normalized their CRP after 3–12 months. Safety: 82.7% of pts reported ≥1 adverse events, most commonly infection and worsening CD symptoms. Discussion Standard VDZ dosing resulted in clinical and endoscopic improvement in pts with moderate-severe CD, with prior exposure to multiple advanced therapies. For non-remitters to standard dosing, modified VDZ maintenance dosing improved clinical disease activity in ∼50% of pts and improved endoscopic disease activity in ∼20% of pts, suggesting that for pts who did not achieve remission with standard VDZ dosing, modified VDZ dosing may result in clinical and endoscopic improvement.

Abstract Background Present therapies leave an unmet need for early and effective treatment for patients with Crohn’s disease (CD). Risankizumab (RZB), a humanized immunoglobulin G1 monoclonal antibody against the p19 subunit of interleukin-23, was evaluated as an induction therapy to induce early clinical remission and response in patients with moderate-to-severe CD in two double-blind, randomized, placebo (PBO)-controlled studies (ADVANCE [NCT03104413] and MOTIVATE [NCT03105128]). Methods Patients with moderate-to-severe CD (CD Activity Index [CDAI] of 220–450, Simple Endoscopic Score for CD [SES-CD] ≥ 6 [≥ 4 for isolated ileal disease] excluding the narrowing component, and average daily [liquid/very soft] stool frequency [SF] ≥ 4 and/or average daily abdominal pain [AP] score ≥ 2) who had inadequate response or intolerance to conventional and/or biologic treatment (ADVANCE), or biologic treatment only (MOTIVATE) were randomised 2:2:1 (ADVANCE) or 1:1:1 (MOTIVATE) to receive intravenous RZB 600 mg, RZB 1200 mg, or PBO as induction therapy at weeks 0, 4, and 8. Clinical remission (per either CDAI or a composite of SF and AP criteria), clinical response (per CDAI criterion), and enhanced clinical response (per a composite of SF and AP criteria) were evaluated at weeks 4, 8, and 12 (endpoints defined in Figure 1 footnotes). Safety was assessed throughout the studies. Results A total of 1419 patients from ADVANCE (N = 850) and MOTIVATE (N = 569) respectively, were randomised and included in the intention-to-treat population. In both studies, starting at week 4 (the first prespecified measurement), greater proportions of RZB 600 mg or RZB 1200 mg- vs PBO-treated patients achieved clinical remission per either CDAI (P = .01/P < .05) or SF/AP criteria (P < .01/P < .01), clinical response per CDAI criterion (P = .001/P < .01), and enhanced clinical response per SF/AP criteria (P < .01/P = .14) (Figure 1). For both RZB 600 mg and RZB 1200 mg, the efficacy and treatment effect increased through week 12 (P ≤ .001/P ≤ .001) (Figure 1). Treatment with RZB 600 mg or 1200 mg was well tolerated, and no new safety risks were identified.1,2 Conclusion Induction therapy with both RZB 600 mg and 1200 mg intravenous resulted in significantly greater clinical remission and response vs PBO as early as week 4 and sustained through week 12 in patients with moderate-to-severe CD who had inadequate response or intolerance to conventional and/or biologic treatment.

The isolated appendiceal Crohn’s disease without preceding bowel symptoms is a rare phenomenon, especially in older patients. In this case report, we present a 60-year-old female with isolated appendiceal Crohn’s disease presenting with acute appendicitis. She presented with classical features of appendicitis with elevated inflammatory markers. She underwent an appendectomy which showed an excessively swollen, oedematous, and reddish appendix with swelling extending to the base of the caecum. Histological evaluation was suggestive of Crohn’s disease, and subsequent colonoscopy was unremarkable. Following appendectomy, she was asymptomatic without any recurrence of disease. The atypical morphological appearance of the appendix should raise suspicion of Crohn’s disease. This case highlights the importance of histopathological analysis of the specimen, especially in abnormal clinical findings. The prognosis of such patients seems to be good, and additional treatment is rarely needed.

Abstract Background In Crohn’s disease (CD), the extensive and potentially transmural inflammation results in increased activity of both matrix metalloproteases (MMPs) and serine proteases, causing a higher degree of intestinal tissue remodelling. This increased proteolytic activity could potentially cause degradation and loss of function of mechanical and functional matrix proteins, such as elastin. Therefore, we sought to investigate the association between biomarkers of elastin degradation and the disease activity in CD patients. Methods Seventy-two CD patients and 29 healthy donors (HD) were included in the study. Disease activity was determined according to the Crohn’s disease activity index score (CDAI >150) and/or a faecal calprotectin (fCALP >250). Additionally, CD patients were endoscopically assessed according to the simple endoscopic score (SES) for CD. Different protease derived biomarkers of elastin degradation: protease-3 (ELP-3), MMP-7 (ELM-7) and cathepsin-G (EL-CG) was measured in serum by ELISA. One-way ANOVA (Kruskal–Wallis) was applied for the statistical analysis. Results The levels of ELP-3 was significantly elevated in active CD when compared with the HD (p < 0.001), and inactive CD (p < 0.01). Levels of EL-G were significantly elevated when comparing active CD and HD (p < 0.05), with the same result observed for the levels of EL-CG when comparing active CD and the HD (p < 0.05). Endoscopically, ELP-3 was shown significantly elevated in moderate–to-severe CD patients when compared with the HD (p < 0.01). Conclusion In this study, measurements of the elastin degradation markers were capable of differentiating between CD patients with either a clinically active or biochemically active disease, with the biomarker levels being significantly highest in the patients with an active disease. This was also the case when assessing endoscopic disease activity, where the protease-3-derived biomarker levels were highest in patients of moderate-to-severe disease activity. As such, the data provide indications of the beneficial use of these serum biomarkers as additional disease activity assessment tools for CD patients.

Abstract Intestinal dysbiosis in inflammatory bowel disease (IBD) patients depend on disease activity. We aimed to characterize the microbiota after 7 years of follow-up in an unselected cohort of IBD patients according to disease activity and disease severity. Fifty eight Crohn’s disease (CD) and 82 ulcerative colitis (UC) patients were included. Disease activity was assessed by the Harvey-Bradshaw Index for CD and Simple Clinical Colitis Activity Index for UC. Microbiota diversity was assessed by 16S rDNA MiSeq sequencing. In UC patients with active disease and in CD patients with aggressive disease the richness (number of OTUs, p = 0.018 and p = 0.013, respectively) and diversity (Shannons index, p = 0.017 and p = 0.023, respectively) were significantly decreased. In the active UC group there was a significant decrease in abundance of the phylum Firmicutes (p = 0.018). The same was found in CD patients with aggressive disease (p = 0.05) while the abundance of Proteobacteria phylum showed a significant increase (p = 0.03) in CD patients. We found a change in the microbial abundance in UC patients with active disease and in CD patients with aggressive disease. These results suggest that dysbiosis of the gut in IBD patients is not only related to current activity but also to the course of the disease.
