IntroductionCrohn’s disease is a chronic inflammatory disease of the gastrointestinal tract with an increasing incidence and prevalence worldwide. The early use of anti-­tumour necrosis factor agents, such as infliximab, in patients with an aggressive form of Crohn’s disease has become part of routine practice. However, infliximab has limitations, and early surgery might benefit patients more. The objective of this study was to compare laparoscopic bowel resection with infliximab treatment in patients with moderately or severely active Crohn’s disease with respect to endoscopic remission. The laparoscopic bowel resection combined with infliximab treatment trial is the first randomised controlled trial to demonstrate if early surgery can improve the outcome of patients with Crohn’s disease with limited non-stricturing disease treated with infliximab.Methods and analysisThis is a randomised, open-label, controlled trial at Renji Hospital. In this study, a total of 106 adult patients aged 18–80 years with moderately or severely active and steroid-dependent or steroid-resistant Crohn’s disease of the distal ileum will be randomly assigned in a 1:1 ratio to the control and surgery groups. The primary outcome is 12-month endoscopic remission measured by the Simple Endoscopic Score for Crohn’s Disease in the control group and the Rutgeerts score in the surgery group. The secondary outcomes are clinical remission, surgery rate, quality of life, Crohn’s disease-related medical costs and Crohn’s disease-related morbidity. The patients will be followed up every 6 months after randomisation through intestinal magnetic resonance enterography and colonoscopy for either 3 years or until clinical remission.Ethics and disseminationAll participants will provide informed consent. The protocol has been approved by the Medical Ethical Committee of the Academic Medical Center in Shanghai (No KY2019-180). Results will be disseminated through peer-reviewed journals and scientific conference presentations.Trial registration numberChiCTR2000029323.

ObjectiveCrohn’s disease (CD) pathogenesis associated with dysbiosis and presence of pathobionts in the lumen, intracellular compartments and epithelial biofilms. Azithromycin is active in all three compartments. Our goal was to evaluate if azithromycin-based therapy can improve response and induce remission compared with metronidazole alone in paediatric CD.DesignThis blinded randomised controlled trial allocated children 5–18 years with 10<Pediatric Crohn’s Disease Activity Index (PCDAI)≤40 to azithromycin 7.5 mg/kg, 5 days/week for 4 weeks and 3 days/week for another 4 weeks with metronidazole 20 mg/kg/day (group 1) or metronidazole alone (group 2), daily for 8 weeks. Failures from group 2 were offered azithromycin as open label. The primary end point was response defined by a decrease in PCDAI>12.5 or remission using intention to treat analysis.Results73 patients (mean age 13.8±3.1 years) were enrolled, 35 to group 1 and 38 to group 2. Response and remission rates at week 8 were identical 23/35 (66%) in group 1 and 17/38 (45%) and 15/38 (39%) in group 2 (P=0.07 and P=0.025, respectively). The needed to treat for remission was 3.7. Faecal calprotectin declined significantly in group 1 (P=0.003) but not in group 2 (p=0.33), and was lower at week 8 (P=0.052). Additional therapy was required in 6/35(17%) from group 1 versus 16/38(42%) in group 2 (P=0.027) by week 8. Among 12 failures in group 2, open-label azithromycin led to remission in 10/12 (83%).ConclusionsThe combination of azithromycin and metronidazole failed to improve response but was superior for induction of remission and reduction in calprotectin.Trial registration numberNCT01596894.

Abstract Background Crohn's disease (CD) is a principal form of inflammatory bowel disease, affecting approximately 1 in every 650 people in the UK. Vitamin D deficiency is common in approximately 57.7% of CD patients; with anaemia occurring in about 43% of patients. There is growing evidence that supplementing CD patients who are vitamin D deficient may be effective in reducing the severity of CD symptoms and reducing iron-deficiency anaemia. Nevertheless, National Institute for Health and Care Excellence guidance regarding the management of CD does not address vitamin D deficiency in these patients. The aims of the study are (1) to determine the prevalence of vitamin D deficiency in adults with CD in Birmingham, UK and (2) to assess the feasibility of conducting a multi-site randomised controlled trial in adult patients with CD and vitamin D deficiency. Methods D-CODE consists of two parts—a screening study and an open-label randomised controlled feasibility study. Vitamin D screening Three hundred patients, 18 years or older with CD will have a dried blood spot test to measure vitamin D levels. Dietary and sun exposure data will be collected. Eligible patients with low levels of vitamin D will be invited to participate in the feasibility study. Feasibility study Fifty participants with CD and vitamin D deficiency will be randomised to receive either a low (400 IU daily for 24 weeks) or high (3200 IU daily for 12 weeks then vitamin D3 800 IU daily for 12 weeks) dose of vitamin D3 oral supplementation. Patient-reported outcomes (Inflammatory Bowel Disease Questionnaire, EQ-5D-5L and Crohn’s Disease Activity Index Score) will be collected at weeks 0 and 24. Biochemical monitoring will take place at weeks 0, 12 and 24 and will measure 25-hydroxyvitamin D, corrected calcium, albumin, parathyroid hormone, hepcidin, other vitamin D metabolites, iron studies and C-reactive protein. Faecal calprotectin will be measured at weeks 0 and 24. Discussion A key aspect of D-CODE is the identification of vitamin D deficiency prior to supplementation. It is hoped that this feasibility study will lead to a definitive trial that will investigate the benefits of treating vitamin D deficiency in patients with CD. Trial registration The trial has been registered with EudraCT number 2018-003910-42, ClinicalTrials.gov identifier NCT03718182 and ISRCTN number 15717783.

Paediatric Crohn’S Disease

Abstract Background In newly diagnosed paediatric Crohn’s disease (CD) patients current guidelines instruct to start exclusive enteral nutrition (EEN) or oral prednisolone in combination with immunomodulators to achieve remission. Infliximab (IFX) is proven to be highly effective in paediatric CD patients, but mostly used once patients are refractory, the so-called step-up (SU) treatment strategy. However, evidence is emerging IFX is more effective if initiated earlier in the disease course. We investigated whether initiation of IFX directly after diagnosis of moderate-to-severe CD, i.e. top-down (TD) treatment, results in a higher long-term remission rate compared with SU treatment. Methods For this international randomised controlled trial (RCT) patients aged 3–17 years, with new-onset, untreated CD with weighted paediatric CD activity index (wPCDAI) &gt;40 were included. TD treatment consisted of 5 IFX (CT-P13) infusions of 5 mg/kg (0, 2, 6, 14, 22 weeks) combined with azathioprine (AZA). After 5 infusions, IFX was stopped while continuing AZA. SU treatment consisted of induction therapy with EEN or oral prednisolone combined with AZA as a maintenance treatment. In both groups, IFX could be (re)started on predefined conditions. The primary endpoint of this study was sustained clinical remission (wPCDAI &lt;12.5) at week 52 without the need for additional therapy or surgery. Secondary endpoints included patient rate using IFX at week 52, mucosal healing (SES-CD &lt;3) and low faecal calprotectin levels (&lt;250 μg/g) at week 10. Results 100 patients were included in 12 centres. Three out of 100 patients did not start with the study after randomisation (n = 97; 49 TD vs. 48 SU). At 52 weeks, 21/48 (44%) of TD patients were in clinical remission without a need for treatment intensification or surgery, while in the SU group this number was significantly lower (8/48, p = 0.004). After induction therapy, IFX was (re)started in 19/49 (39%) TD patients compared with 30/48 (62%) SU patients within 52 weeks (p = 0.019). At week 10, significantly more TD (27/44, 61%) than SU treated patients (17/44, 39%) were in clinical remission (p = 0.033). Fifty-seven of 97 consented to endoscopy at week 10. Endoscopic remission rates were higher in TD (16/27 [59%], median SES-CD 1 [IQR 0–5]) than SU treated patients (5/30 [17%], median SES-CD 6 [IQR 3–16], p = 0.001). Similarly, low faecal calprotectin levels were more frequent in the TD group (n = 75; TD 21/40 [53%] vs. SU 9/35 [26%], p = 0.027). Conclusion We are the first to compare TD IFX to SU treatment in an RCT of paediatric CD patients. TD treatment was superior to SU in achieving sustained clinical remission. Therefore, we advise to start IFX directly after diagnosis in moderate-to-severe paediatric Crohn’s disease patients.

IntroductionPerianal fistulising Crohn’s disease (pfCD) can be somewhat treatment refractory. Higher infliximab trough levels (TLIs) may improve fistula healing rates; however, it remains unclear whether escalating infliximab therapy to meet higher TLI targets using proactive, or routine, therapeutic drug monitoring (TDM) improves outcomes. This randomised controlled trial aimed to assess whether infliximab therapy targeting higher TLIs guided by proactive TDM improves outcomes compared with standard therapy.Methods and analysisPatients with active pfCD will be randomised 1:1 to either the proactive TDM arm or standard dosing arm and followed up for 54 weeks. Patients in the proactive TDM arm will have infliximab dosing optimised to target higher TLIs. The targets will be TLI ≥ 25 µg/mL at week 2, ≥ 20 µg/mL at week 6 and ≥ 10 µg/mL during maintenance therapy. The primary objective will be fistula healing at week 32. Secondary objectives will include fistula healing, fistula closure, radiological fistula healing, patient-reported outcomes and economic costs up to 54 weeks. Patients in the standard dosing arm will receive conventional infliximab dosing not guided by TLIs (5 mg/kg at weeks 0, 2 and 6, and 5 mg/kg 8 weekly thereafter). Patients aged 18–80 years with pfCD with single or multiple externally draining complex perianal fistulas who are relatively naïve to infliximab treatment will be included. Patients with diverting ileostomies or colostomies and pregnant or breast feeding will be excluded. Fifty-eight patients per arm will be required to detect a 25% difference in the primary outcome measure, with 138 patients needed to account for an estimated 6.1% primary non-response rate and 10% dropout rate.Ethics and disseminationResults will be presented in peer-reviewed journals and international conferences. Ethics approval has been granted by the South Western Sydney Local Health District Human Research Ethics Committee in Australia.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12621000023853); Pre-results.

ObjectiveIn newly diagnosed paediatric patients with moderate-to-severe Crohn’s disease (CD), infliximab (IFX) is initiated once exclusive enteral nutrition (EEN), corticosteroid and immunomodulator therapies have failed. We aimed to investigate whether starting first-line IFX (FL-IFX) is more effective to achieve and maintain remission than conventional treatment.DesignIn this multicentre open-label randomised controlled trial, untreated patients with a new diagnosis of CD (3–17 years old, weighted Paediatric CD Activity Index score (wPCDAI) >40) were assigned to groups that received five infusions of 5 mg/kg IFX at weeks 0, 2, 6, 14 and 22 (FL-IFX), or EEN or oral prednisolone (1 mg/kg, maximum 40 mg) (conventional). The primary outcome was clinical remission on azathioprine, defined as a wPCDAI <12.5 at week 52, without need for treatment escalation, using intention-to-treat analysis.Results100 patients were included, 50 in the FL-IFX group and 50 in the conventional group. Four patients did not receive treatment as per protocol. At week 10, a higher proportion of patients in the FL-IFX group than in the conventional group achieved clinical (59% vs 34%, respectively, p=0.021) and endoscopic remission (59% vs 17%, respectively, p=0.001). At week 52, the proportion of patients in clinical remission was not significantly different (p=0.421). However, 19/46 (41%) patients in the FL-IFX group were in clinical remission on azathioprine monotherapy without need for treatment escalation vs 7/48 (15%) in the conventional group (p=0.004).ConclusionsFL-IFX was superior to conventional treatment in achieving short-term clinical and endoscopic remission, and had greater likelihood of maintaining clinical remission at week 52 on azathioprine monotherapy.Trial registration numberClinicalTrials.gov Registry (NCT02517684).

Background: Thalidomide is effective in inducing and maintaining clinical remission in children and adolescents with refractory Crohn’s disease (CD). However, little is known about the efficacy and safety of thalidomide for adult patients with CD. Methods: We conducted a prospective open-label cohort study between January 2013 and April 2015. A total of 47 adult patients with active CD who were dependent/resistant or intolerant to corticosteroids and/or immunomodulators or biologics received 50–100 mg of thalidomide daily. Primary outcome was clinical remission evaluated at week 8. Endoscopic assessment was performed at week 24 and defined as endoscopic response (decrease in Crohn’s Disease Endoscopic Index of Severity [CDEIS] score > 5 points from baseline CDEIS of 6 or more), complete endoscopic remission (CDEIS score < 3), and mucosal healing (MH) (no ulceration). Results: A total of 47 adults with active CD were enrolled. The clinical remission rate was 14.9% and 23.4% at week 4 and week 8, but increased to 46.8% at week 12 and 53.2% at week 24 out of all the 47 patients included (intention-to-treat analysis). Altogether 32 patients consented and underwent ileocolonoscopy at week 24. The rate of endoscopic response and complete endoscopic remission were 68.4% and 43.8%. MH (no ulceration) was achieved in 28.1% of patients. Adverse events occurred in 27/47 (57.4%) patients but necessitated therapy discontinuation in only 5/47 (10.6%) of patients. Conclusions: Low-dose thalidomide was effective and tolerated for inducing and maintaining clinical remission in adult patients with active CD, but the optimal time frame for thalidomide to induce clinical remission may be longer than previously appreciated and is probably optimal at 12 weeks. MH could reasonably be achievable with thalidomide.

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 &gt;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.
