RESUMO
BACKGROUND: Although ulcerative proctitis [UP] can dramatically impair quality of life, treatment efficacy has been poorly investigated in UP as it was historically excluded from phase 2/3 randomised controlled trials in ulcerative colitis. Our aim was to assess the effectiveness and safety of tofacitinib for the treatment of UP. METHODS: We conducted a retrospective, multicentre study in 17 GETAID centres, including consecutive patients with UP treated with tofacitinib. The primary endpoint was steroid-free remission between Week 8 and Week 14, defined as a partial Mayo score of 2 [and no individual subscore above 1]. Secondary outcomes included clinical response and steroid-free remission after induction and at 1 year. RESULTS: All the 35 enrolled patients previously received anti-tumour necrosis factor [TNF] therapy and 88.6% were exposed to at least two lines of biologics. At baseline, the median partial Mayo score was 7 (intequartile range [IQR] [5.5-7]). After induction [W8-W14], 42.9% and 60.0% of patients achieved steroid-free remission and clinical response, respectively. At 1 year, the steroid-free clinical remission and clinical response rates were 39.4% and 45.5%, respectively, and 51.2% [17/33] were still receiving tofacitinib treatment. Survival without tofacitinib withdrawal was estimated at 50.4% (95% confidence interval [CI] [35.5-71.6]) at 1 year. Only a lower partial Mayo at baseline was independently associated with remission at induction (0dds ratio [OR]â =â 0.56 for an increase of 1, (95% CI [0.33-0.95], pâ =â 0.03). Five [14.3%] adverse events were reported, with one leading to treatment withdrawal [septic shock secondary to cholecystitis]. CONCLUSION: Tofacitinib may offer a therapeutic option for patients with refractory UP.

BACKGROUND: IBD is associated with an increased risk of developing lymphoma. Although recent data clarifies lymphoma epidemiology in IBD patients, clinical and pathological characteristics of lymphoma occurring in IBD remain ill-known. METHODS: Patients with IBD and lymphoma were retrospectively identified in the framework of a national collaborative study including the Groupe d'Étude Thérapeutique des Affections Inflammatoires du Tube Digestif (GETAID) and the Lymphoma Study Association (LYSA). We characterized clinical and prognostic features for the 3 most frequent lymphoma subtypes occurring in IBD. We performed a multicentric case-control study. Controls (lymphoma de novo) were matched (5:1) to cases on gender, age at diagnosis, lymphoma subtype, year of diagnosis, IPI/FLIPI indexes. Overall survival (OS) and progression free survival were compared between cases and controls. RESULTS: 133 IBD patients with lymphoma were included (males = 62.4 %, median age at lymphoma diagnosis = 49 years in males ; 42 in females). Most had Crohn's disease (73.7 %) and were exposed to thiopurines (59.4 %). The most frequent lymphoma subtypes were diffuse large B cell lymphoma (DLBCL, 45.1 %), Hodgkin lymphoma (HL, 18.8 %), and follicular lymphoma (FL, 10.5 %). When matched with 365 controls, prognosis was improved in IBD patients with DLBCL compared to controls (p = 0.0064, hazard ratio = 0.36) or similar (HL and FL). CONCLUSION: Lymphomas occurring in IBD patients do not seem to have a worse outcome than in patients without IBD. Due to the scarcity of this situation, those patients should be managed in expert centers.
RESUMO
BACKGROUND: Numerous biologic drugs, including etanercept and adalimumab, are administered subcutaneously. This study reviewed the evidence on the usability and preference of self-injection devices of SB4 and SB5 compared with the reference product injectors. METHODS: A systematic search was conducted in PubMed using the search string "(Imraldi OR Hadlima OR SB5 OR Benepali OR Brenzys OR SB4) AND (preference) AND (device)" covering the period from 28 January 2016 (first introduction of SB4) to 31 May 2022. Only articles and abstracts on usability or preference-rating of SB4 and SB5 autoinjectors (AI) written in English were selected. Additional papers identified via manual search supplemented the retrieved papers. RESULTS: A total of nine articles and one conference poster were selected (seven surveys, one observational study, and two phase II studies). Overall, participants of the studies included nurses and rheumatologists, as well as patients who were from three medical specialties where these medicines are most commonly used (rheumatology, gastroenterology, and dermatology). The majority of patients and healthcare professionals rated ease of use and ease of grip as the most important device attributes. SB4/Pen and SB5/Pen were mostly preferred over their prefilled syringes (PFS), Enbrel/Pen, and Humira/Pen. CONCLUSION: The analyzed data on usability and device preference indicate that SB4/Pen and SB5/Pen were preferred over the other reference product autoinjectors, thanks to their button-free design, auditory and visual injection feedback, and overall ease of use. Therefore, they were preferred over the other reference product autoinjectors. Because user-friendly devices can improve treatment adherence, pharmaceutical companies should consider patient convenience when developing medical devices.

BACKGROUND: SB5 is an EMA-approved adalimumab biosimilar, having demonstrated bioequivalence, equivalent efficacy, and similar safety and immunogenicity to the reference product. AIMS: Describe patient training and satisfaction using patient-reported outcome measures (PROMs) and assess their impact on 12-month persistence on SB5. METHODS: The observational PERFUSE study included 318 Crohn's disease (CD) patients and 88 ulcerative colitis (UC) patients in 27 sites across France between October 2018 and December 2020. PROMs were collected at 1-month post-baseline using an online questionnaire (ePRO) designed with patient associations. Treatment persistence was collected during routine visits (up to 15 months post-initiation). Results are presented by prior experience with subcutaneous biologics and training in proper use of the injection device. RESULTS: 57.1% (n = 145) and 44.1% (n = 67) of naïve and pre-treated patients, respectively, answered the ePRO. Naïve patients were offered training more often (86.9% vs 31.3% respectively, p < 0.05), with disparities between sites. All subgroups' satisfaction scores were high. 12-month persistence on SB5 was significantly higher for respondents than for non-respondents (68.0% [60.9; 74.1] vs 52.3% [44.5; 59.6]; p < 0.05) and in patients with a better perception of their illness (OR=1.02, [1.0; 1.05]; p < 0.05). CONCLUSIONS: Early patient questionnaires may be useful to identify patients at higher risk of treatment discontinuation.

BACKGROUND: In recent years, an increasing prevalence of obesity in inflammatory bowel disease (IBD) has been observed. However, only a few studies have focused on the impact of overweight and obesity on IBD-related disability. AIMS: To identify the factors associated with obese and overweight patients with IBD, including IBD-related disability. PATIENTS AND METHODS: In this cross-sectional study, we included 1704 consecutive patients with IBD in 42 centres affiliated with the Groupe d'Etude Therapeutique des Affections Inflammatoires du tube Digestif (GETAID) using a 4-page questionnaire. Factors associated with obesity and overweight were assessed using univariate and multivariate analyses (odds ratios (ORs) are provided with 95% confidence intervals). RESULTS: The prevalence rates of overweight and obesity were 24.1% and 12.2%, respectively. Multivariable analyses were stratified by age, sex, type of IBD, clinical remission and age at diagnosis of IBD. Overweight was significantly associated with male sex (OR = 0.52, 95% CI [0.39-0.68], p < 0.001), age (OR = 1.02, 95% CI [1.01-1.03], p < 0.001) and body image subscore (OR = 1.15, 95% CI [1.10-1.20], p < 0.001) (Table 2). Obesity was significantly associated with age (OR = 1.03, 95% CI [1.02-1.04], p < 0.001), joint pain subscore (OR = 1.08, 95% CI [1.02-1.14], p < 0.001) and body image subscore (OR = 1.25, 95% CI [1.19-1.32], p < 0.001) (Table 3). CONCLUSION: The increasing prevalence of overweight and obesity in patients with IBD is associated with age and poorer body image. A holistic approach to IBD patient care should be encouraged to improve IBD-related disability and to prevent rheumatological and cardiovascular complications.

Objective: PERFUSE is a non-interventional study of 1233 adult patients (rheumatology, n = 496; IBD, n = 737) receiving routine infliximab (IFX) biosimilar SB2 therapy. The aim of this report was to investigate the 12-month persistence, effectiveness and safety outcomes of routine SB2 treatment in patients with chronic inflammatory rheumatic disease. Methods: Patients with a diagnosis of RA, PsA or axial spondyloarthritis (axSpA) were assigned to one of three study cohorts according to whether SB2 treatment initiated after September 2017 had been the first IFX treatment (IFX naïve) or followed transition from reference IFX (IFX ref) or another IFX biosimilar (IFX bs). Outcomes to month 12 (±2) included persistence (primary outcome), SB2 dose, disease status, immunogenicity and safety. Results: At month 12, persistence on SB2 in IFX-naïve, IFX ref and IFX bs cohorts, respectively, [mean percentage (95% CI)] by indication was as follows: 59% (36.1, 76.2), 75% (57.5, 86.1) and 85% (69.6, 93.0) for RA (n = 98); 64% (34.3, 83.3), 87% (65.6, 95.7) and 83% (60.0, 93.1) for PsA (n = 62); and 56% (44.4, 66.5), 80% (70.8, 86.1) and 80% (72.5, 85.6) for axSpA (n = 336). Disease activity was comparable at baseline and month 12 within the IFX ref and bs subgroups of all cohorts by indication. No immunogenicity concerns or new safety signals were detected. Conclusion: SB2 was safe and effective in IFX-naïve patients and in patients transitioned from prior IFX ref or bs. Trial registration: clinicaltrials.gov, NCT03662919.
RESUMO
Background: FlixabiTM (SB2) is a biosimilar of the reference infliximab (IFX), Remicade®. Published evidence on long-term, real-world use of SB2 in patients either IFX naive or transitioned from prior IFX is scarce. Objectives: We evaluated persistence, effectiveness, and safety of SB2 over 12 months in adults with IBD [Crohn's disease (CD) and ulcerative colitis (UC)], participating in PERFUSE. Design: PERFUSE is a long-term, non-interventional, multicenter study of patients receiving SB2 at specialist sites across France. Methods: SB2 treatment was initiated in September 2017, either as first IFX treatment (IFX naive), after transition from treatment with reference IFX (IFX ref) or another IFX biosimilar (IFX bs), or both IFX ref and IFX bs (IFX multiswitch). Outcomes up to Month 12 (±2) include persistence on SB2 (primary outcome measure), SB2 dose, disease status, immunogenicity, and safety. Results: This final 12-month analysis of patients with IBD includes 569 with CD and 168 with UC. Persistence [95% confidence interval (CI)] at Month 12 was CD: 89% (77.2; 94.9), UC: 78.5% (58.2; 89.8) for IFX naive; CD: 94% (91.0; 96.1), UC: 92.8% (84.8; 96.7) for IFX ref; CD: 91.6% (86.0; 95.0), UC: 94.2% (83.1; 98.1) for IFX bs; and CD 100% (100; 100), UC 100% (100; 100) for IFX multiswitch. In the CD and UC cohorts, disease activity among IFX naive patients declined from baseline to Month 12; with any prior IFX, the proportions of patients in remission at baseline, Month 6, and Month 12 remained unchanged in the UC cohort, and were comparable or higher in the CD cohort. No immunogenicity or safety signals were detected. Conclusions: Patients with IBD can be initiated on SB2 or transitioned from IFX ref and/or IFX bs to SB2, with no loss of disease control or safety concerns, with >75% of naive and >90% of transitioned patients continuing on SB2 treatment at 12 months.
RESUMO
BACKGROUND: Fatigue is commonly reported by patients with inflammatory bowel disease [IBD], but the determinants of IBD-related fatigue have yet to be determined. AIMS: To identify the factors associated with fatigue in a large population of patients with IBD. PATIENTS AND METHODS: Fatigue and nine other IBD-related disability dimensions were assessed in a cohort of 1704 consecutive patients with IBD using the IBD-disk questionnaire in a cross-sectional survey of 42 French and Belgian centres. Fatigue and severe fatigue were defined as energy subscores >5 and >7, respectively. Determinants of fatigue were assessed using univariate and multivariate analyses (odds ratios [ORs] are provided with 95% confidence intervals). RESULTS: The prevalence rates of fatigue and severe fatigue were 54.1% and 37.1%, respectively. Both fatigue and severe fatigue were significantly higher in patients with active disease than in patients with inactive disease [64.9% vs 44.7% and 47.4% vs 28.6%, respectively; pâ <â 0.001 for both comparisons]. In the multivariate analysis stratified by age, sex, type of IBD and IBD activity, fatigue was associated with age >40 years (ORâ =â 0.71 [0.54-0.93]), female sex (ORâ =â 1.48 [1.13-1.93]) and IBD-related sick leave (ORâ =â 1.61 [1.19-2.16]), and joint pain (ORâ =â 1.60 [1.17-2.18]), abdominal pain (ORâ =â 1.78 [1.29-2.45]), regulating defecation (ORâ =â 1.67 [1.20-2.32]), education and work (ORâ =â 1.96 [1.40-2.75]), body image (ORâ =â 1.38 [1.02-1.86]), sleep (ORâ =â 3.60 [2.66-4.88]) and emotions (ORâ =â 3.60 [2.66-4.88]) subscores >5. CONCLUSION: Determinants of fatigue are not restricted to IBD-related factors but also include social factors, sleep and emotional disturbances, thus supporting a holistic approach to IBD patient care.
RESUMO
BACKGROUND & AIMS: The management of intra-abdominal abscesses complicating Crohn's disease (CD) is challenging, and surgery with delayed intestinal resection is often recommended. The aims of this study were to estimate the success rate of adalimumab (ADA) in patients with CD with an intra-abdominal abscess resolved without surgery, and to identify predictive factors for success. METHODS: A multicenter, prospective study was conducted in biologic-naïve patients with CD with resolved intra-abdominal abscess treated with ADA with a 2-year follow-up. The primary endpoint was ADA failure at week (W) 24 defined as a need for steroids after W12, intestinal resection, abscess recurrence, and clinical relapse. Secondary post-hoc endpoint was the long-term success defined as the survival without abscess relapse or intestinal resection at W104. The factors associated with ADA failure at W24 and W104 were identified using a logistic and a Cox regression, respectively. RESULTS: From April 2013 to December 2017, 190 patients from 27 GETAID centers were screened, and 117 were included in the analysis. Fifty-eight patients (50%) were male, and the median age at baseline was 28 years. At W24, 87 patients (74%; 95% confidence interval [CI], 65.5%-82.0%; n = 117) achieved ADA success. Among the 30 patients with ADA failure, 15 underwent surgery. At W104, the survival rate without abscess recurrence or surgery was 72.9% (95% CI, 62.1%-79.8%; n = 109). Abscess drainage was significantly associated with ADA failure at W24 (odds ratio, 4.18; 95% CI, 1.06-16.5; P =0 .043). Disease duration (hazard ratio [HR], 1.32; 95% CI, 1.09-1.59; P = .008), abscess drainage (HR, 5.59; 95% CI, 2.21-14.15; P = .001), and inflammatory changes in mesenteric fat (HR, 0.4; 95% CI, 0.17-0.94; P = .046) were significantly associated with ADA failure at W104. CONCLUSION: Provided that the abscess was carefully managed before initiating medical treatment, this study showed the high efficacy of ADA in the short and long term in biologic-naïve patients with CD complicated by an intra-abdominal abscess.

BACKGROUND: Rates of enrolment in clinical trials in inflammatory bowel disease [IBD] have decreased dramatically in recent years. This has led to delays, increased costs and failures to develop novel treatments. AIMS: The aim of this work is to describe the current bottlenecks of IBD clinical trial enrolment and propose solutions. METHODS: A taskforce comprising experienced IBD clinical trialists from academic centres and pharmaceutical companies involved in IBD clinical research predefined the four following levels: [1] study design, [2] investigative centre, [3] physician and [4] patient. At each level, the taskforce collectively explored the reasons for declining enrolment rates and generated an inventory of potential solutions. RESULTS: The main reasons identified included the overall increased demands for trials, the high screen failure rates, particularly in Crohn's disease, partly due to the lack of correlation between clinical and endoscopic activity, and the use of complicated endoscopic scoring systems not reflective of the totality of inflammation. In addition, complex trial protocols with restrictive eligibility criteria, increasing burden of procedures and administrative tasks enhance the need for qualified resources in study coordination. At the physician level, lack of dedicated time and training is crucial. From the patients' perspective, long washout periods from previous medications and protocol requirements not reflecting clinical practice, such as prolonged steroid management and placebo exposures, limit their participation in clinical trials. CONCLUSION: This joint effort is proposed as the basis for profound clinical trial transformation triggered by investigative centres, contract research organizations, sponsors and regulatory agencies.

OBJECTIVES: PERFUSE is a non-interventional study of 1233 patients [inflammatory rheumatic disease, n = 496; inflammatory bowel disease (IBD), n = 737] receiving infliximab (IFX) biosimilar SB2 therapy. This analysis describes response to treatment and persistence on SB2 for up to 12 months in pediatric IBD patients (n = 126). METHODS: Pediatric IBD patients with Crohn disease (CD) or ulcerative colitis (UC), either naïve or switched from originator IFX, who started SB2 in routine practice after September 2017 were eligible. Data were captured for 12 months following SB2 initiation. Disease activity was measured using C-reactive protein (CRP) levels and the Harvey-Bradshaw Index or Pediatric Ulcerative Colitis Activity Index for CD and UC patients, respectively. Body mass index and height z scores were used to assess patient growth between initiation (M0) and month 12 (M12). RESULTS: One hundred twenty-six pediatric IBD patients were included (102 CD patients, 51 naïve and 51 switched; 24 UC patients, 9 naïve and 15 switched). Naive patients' disease scores decreased between M0 and M12. CRP measurements also decreased in naïve CD patients. Switched patients' disease scores and CRP levels remained stable between M0 and M12. Height z scores improved significantly over the course of the treatment for all groups except for naïve UC patients. CONCLUSIONS: SB2 provides effective disease control for naïve and switched pediatric patients. Clinical remission rates improved in naïve patients and no loss of control was observed in switched patients after 1 year. Growth failure is not observed in IBD patients under SB2 treatment.

BACKGROUND: The combination of infliximab and immunosuppressant therapy is a standard management strategy for patients with Crohn's disease. Concerns regarding the implications of long-term combination therapy provided the rationale for a formal clinical trial of treatment de-escalation. Our aim was to compare the relapse rate and the time spent in remission over 2 years between patients continuing combination therapy and those stopping infliximab or immunosuppressant therapy. METHODS: This multicentre, open-label, randomised controlled trial was performed in 64 hospitals in seven countries in Europe and Australia. Adult patients with Crohn's disease in steroid-free clinical remission for more than 6 months, on combination therapy of infliximab and immunosuppressant therapy for at least 8 months were randomly assigned (1:1:1) to either continue combination therapy (combination group), discontinue infliximab (infliximab withdrawal group), or discontinue immunosuppressant therapy (immunosuppressant withdrawal group). Randomisation was stratified according to disease duration before start of first anti-TNF treatment (≤2 or >2 years), failure of immunosuppressant therapy before start of infliximab, and presence of ulcers at baseline endoscopy. The patient number and group of each stratum were assigned by a central online randomisation website. Treatment was optimised or resumed in case of relapse in all groups. Participants, those assessing outcomes, and those analysing the data were not masked to group assignment. The coprimary endpoints were the relapse rate (superiority analysis) and time in remission over 2 years (non-inferiority analysis, non-inferiority margin 35 days). Analyses were done on an intention-to-treat basis. This study is registered with ClinicalTrials.gov, NCT02177071, and with EU Clinical Trials Register, EUDRACT 2014-002311-41. The trial was completed in April, 2021. FINDINGS: Between Nov 2, 2015, and April 24, 2019, 254 patients were screened. Of these, 211 were randomised and 207 were included in the final analysis (n=67 in the combination group, n=71 in the infliximab withdrawal group, and n=69 in the immunosuppressant withdrawal group). 39 patients had a relapse (eight [12%] of 67 in the combination group, 25 [35%] of 71 in the infliximab withdrawal group, six [9%] of 69 in the immunosuppressant withdrawal group). 2-year relapse rates were 14% (95% CI 4-23) in the combination group, 36% (24-47) in the infliximab withdrawal group, and 10% (2-18) in the immunosuppressant withdrawal group (hazard ratio [HR] 3·45 [95% CI 1·56-7·69], p=0·003, for infliximab withdrawal vs combination, and 4·76 [1·92-11·11], p=0·0004, for infliximab withdrawal vs immunosuppressant withdrawal). Of 28 patients who had a relapse and were retreated or optimised according to protocol, remission was achieved in 25 patients (one of two in the combination group, 22 of 23 in the infliximab withdrawal group, and two of three in the immunosuppressant withdrawal group). The mean time spent in remission over 2 years was 698 days (95% CI 668-727) in the combination group, 684 days (651-717) in the infliximab withdrawal group, and 706 days (682-730) in the immunosuppressant withdrawal group. The difference in restricted mean survival time in remission was -14 days (95% CI -56 to 27) between the infliximab withdrawal group and the combination group and -22 days (-62 to 16) between the infliximab withdrawal group and the immunosuppressant withdrawal group. The 95% CIs contained the non-inferiority threshold (-35 days). We recorded 31 serious adverse events, in 20 patients, with no difference in frequency between groups. The most frequent serious adverse events were infections (four in the combination group, two in the infliximab withdrawal group, and one in the immunosuppressant withdrawal group) and Crohn's disease exacerbation (three in the combination group, four in the infliximab withdrawal group, and one in the immunosuppressant withdrawal group). No death nor malignancy was recorded. INTERPRETATION: In patients with Crohn's disease in sustained steroid-free remission under combination therapy with infliximab and immunosuppressant therapy, withdrawal of infliximab should only be considered after careful assessment of risks and benefits for each patient, whereas withdrawal of immunosuppressant therapy could generally represent a preferable strategy when considering treatment de-escalation.

INTRODUCTION: Multiple chronic ulcers of small intestine are mainly ascribed to Crohn's disease. Among possible differential diagnoses are chronic ulcers of small bowel caused by abnormal activation of the prostaglandin pathway either in the archetypal but uncommon non-steroidal anti-inflammatory drug [NSAID]-induced enteropathy, or in rare monogenic disorders due to PLA2G4A and SLCO2A1 mutations. SLCO2A1 variants are responsible for CEAS [chronic enteropathy associated with SLCO2A1], a syndrome which was exclusively reported in patients of Asian origin. Herein, we report the case of two French female siblings, P1 and P2, with CEAS. CASE REPORT: P1 underwent iterative bowel resections [removing 1 m of small bowel in total] for recurrent strictures and perforations. Her sister P2 had a tight duodenal stricture which required partial duodenectomy. Next-generation sequencing was performed on P1's DNA and identified two compound heterozygous variants in exon 12 in SLCO2A1, which were also present in P2. CONCLUSION: CEAS can be detected within the European population and raises the question of its incidence and recognition outside Asia. Presence of intractable recurrent ulcerations of the small intestine, mimicking Crohn's disease with concentric strictures, should motivate a genetic search for SLCO2A1 mutations, particularly in the context of family history or consanguinity.

BACKGROUND: Inflammatory bowel disease (IBD) guidelines recommend tumor necrosis factor-α inhibitors (TNFis) for patients who have not responded to conventional therapy, and vedolizumab in case of inadequate response to conventional therapy and/or TNFis. Recent studies have shown that vedolizumab may also be effective in the earlier treatment lines. Therefore, we conducted cost-effectiveness analyses to determine the optimal treatment sequence in patients with IBD. METHODS: A Markov model with a 10-year time horizon compared the cost-effectiveness of different biologic treatment sequences in patients with moderate to severe ulcerative colitis (UC) and Crohn's disease (CD) from the UK and French perspectives. Subcutaneous formulations of infliximab, vedolizumab, and adalimumab were evaluated. Comparative effectiveness was based on a network meta-analysis of clinical trials and real-world evidence. Costs included pharmacotherapy, surgery, adverse events, and disease management. RESULTS: The results indicated that treatment sequences starting with infliximab were less costly and more effective than those starting with vedolizumab for patients with UC in the United Kingdom and France, and patients with just CD in France. For patients with CD in the United Kingdom, treatment sequences starting with infliximab resulted in better health outcomes with incremental cost-effectiveness ratios (ICERs) near the threshold. CONCLUSIONS: Based on the ICERs, treatment sequences starting with infliximab are the dominant option for patients with UC in the United Kingdom, and patients with UC and CD in France. In UK patients with CD, ICERs were near the assumed "willingness to pay" threshold. These results reinforce the UK's National Institute for Health and Care Excellence recommendations for using infliximab prior to using vedolizumab in biologics-naïve patients.
A Markov model compared the cost-effectiveness of biologic treatment sequences in patients with moderate to severe inflammatory bowel diseases from a European perspective. The results indicated that treatment sequences starting with infliximab are the dominant option than those starting with vedolizumab.

OBJECTIVE: Despite being in sustained and stable remission, patients with Crohn's disease (CD) stopping anti-tumour necrosis factor α (TNFα) show a high rate of relapse (~50% within 2 years). Characterising non-invasively the biological profiles of those patients is needed to better guide the decision of anti-TNFα withdrawal. DESIGN: Ninety-two immune-related proteins were measured by proximity extension assay in serum of patients with CD (n=102) in sustained steroid-free remission and stopping anti-TNFα (infliximab). As previously shown, a stratification based on time to clinical relapse was used to characterise the distinct biological profiles of relapsers (short-term relapsers: <6 months vs mid/long-term relapsers: >6 months). Associations between protein levels and time to clinical relapse were determined by univariable Cox model. RESULTS: The risk (HR) of mid/long-term clinical relapse was specifically associated with a high serum level of proteins mainly expressed in lymphocytes (LAG3, SH2B3, SIT1; HR: 2.2-4.5; p<0.05), a low serum level of anti-inflammatory effectors (IL-10, HSD11B1; HR: 0.2-0.3; p<0.05) and cellular junction proteins (CDSN, CNTNAP2, CXADR, ITGA11; HR: 0.4; p<0.05). The risk of short-term clinical relapse was specifically associated with a high serum level of pro-inflammatory effectors (IL-6, IL12RB1; HR: 3.5-3.6; p<0.05) and a low or high serum level of proteins mainly expressed in antigen presenting cells (CLEC4A, CLEC4C, CLEC7A, LAMP3; HR: 0.4-4.1; p<0.05). CONCLUSION: We identified distinct blood protein profiles associated with the risk of short-term and mid/long-term clinical relapse in patients with CD stopping infliximab. These findings constitute an advance for the development of non-invasive biomarkers guiding the decision of anti-TNFα withdrawal.

Inflammatory bowel diseases (IBDs) can be associated with various musculoskeletal (IBD-MSK) manifestations that could be difficult to classify for gastroenterologists. We aimed to evaluate the characteristics of patients with IBD-MSK and the prevalence of spondyloarthritis (SpA). In this observational cross-sectional study, we included patients with IBD-MSK complaints (peripheral or back pain). All patients underwent a standardized rheumatology evaluation including clinical, biological and imaging evaluations (MRI of spine and sacroiliac joints and ultrasonography of enthesis). We included 183 IBD patients (60.7% women; median [interquartile range] age 45 [36-56] years); 159 (87%) had joint pain. In 43 (23.5%) and 25/175 (14.3%) patients, enthesis abnormalities were found on ultrasonography and sacroiliitis on MRI, respectively. SpA was diagnosed in 54 (29.5%) patients. IBD-related arthralgia and degenerative spine disease were diagnosed in 105 (57.4%) and 72 (39.3%) patients. Sixteen (29.6%) SpA patients initiated a new conventional synthetic disease modifying anti-rheumatic drug (DMARD). A biologic DMARD was initiated in 10 patients or changed in 3. More than half of IBD-MSK patients had IBD-related arthralgia, and about one-third had definite SpA. Ultrasonography of enthesis and systematic MRI of sacroiliac joints seem useful for SpA classification and differential diagnosis in these patients who often have musculoskeletal pain complaints. Therapeutics were changed in most patients, which highlights the need for a multidisciplinary approach for managing IBD with extra-intestinal symptoms.

BACKGROUND: Despite regular need for colonoscopy in patients with Crohn's disease (CD), the efficacy and tolerability of bowel preparation (BP) agents is rarely assessed in this population. Assessing BP quality with existing scales may be challenging in CD due to presence of inflammation, bowel resection, and strictures. AIMS: To provide recommendations for assessing BP quality in clinical trials for CD using a modified Research and Development/University of California, Los Angeles appropriateness process. METHODS: Based on systematic reviews and a literature search, 110 statements relating to BP quality assessment in CD were developed. A panel of 15 gastroenterologists rated the statements as appropriate, uncertain, or inappropriate using a 9-point Likert scale. RESULTS: Panelists considered it appropriate that central readers, either alone or with local assessment, score BP quality in clinical trials. Central readers should be trained on scoring BP quality and local endoscopists on performing high-quality video recording. Both endoscope insertion and withdrawal phases should be reviewed to score BP quality in each colonic segment and segments should align with endoscopic disease activity indices. The Harefield Cleansing Scale and the Boston Bowel Preparation Scale were considered appropriate. The final score should be calculated as the average of all visualized segments. Both total and worst segment scores should also be assessed. CONCLUSIONS: We developed a framework for assessing BP quality in patients with CD based on expert feedback. This framework could support the development or refinement of BP quality scales and the integration of BP quality assessment in future CD studies.

Management of intra-abdominal abscesses complicating Crohn's disease (CD) is challenging. After initial drainage and antibiotherapy treatment, surgery with delayed intestinal resection is often recommended but new data suggests efficacy of biotherapies in this context. This review aims to summarize new data regarding efficacy and safety of anti-TNF in the management of intra-abdominal abscesses complicating CD. We performed a review of the literature on medical management of intra-abdominal abscesses complicating CD. After effective drainage of abscess, treatment with anti-TNF can allow resolving of abscess. In some patients and at a specific timing, the use of biotherapies could avoid delayed surgery and long-term abscess recurrence.

INTRODUCTION: The objective of this study was to describe the efficacy and safety of infliximab (IFX) reintroduction in Crohn's disease (CD) after stopping for loss of response or intolerance. METHODS: We conducted a prospective multicenter observational cohort study including adult patients with clinically (CD Activity Index >150) and objectively active luminal CD in whom IFX was reintroduced after at least 6 months of discontinuation. The reasons for the initial discontinuation could be a secondary loss of response or IFX intolerance. The reintroduction schedule included 3 IFX infusions at weeks 0, 4, and 8, after a systematic premedication. The primary end point was the efficacy of IFX retreatment at week 26 defined by a CD Activity Index of <150 in the absence of IFX discontinuation or use of corticosteroids, surgery, or other biologic. RESULTS: At week 26, 24 patients (35%) among the 69 analyzed reached the primary end point. No significant difference was observed between rates of clinical remission at week 26 in patients with prior LOR (n = 48) and those with IFX intolerance (n = 21) (35% and 33%, P = 0.87, respectively). Thirty-two acute infusion reactions were recorded in 27 patients, leading to withdrawal of IFX in 20 patients. No pharmacokinetic characteristic at baseline but detection of positive anti-drug antibodies at week 4 was predictive of IFX failure or infusion reaction at week 26. DISCUSSION: In this first prospective cohort study, IFX retreatment was safe and effective in one-third of the patients with CD, regardless the reason of prior discontinuation. Early detection of anti-drug antibodies can predict subsequent IFX reintroduction failure and infusion reactions.
