This study was done to examine the intestinal absorption and cleavage of 9-cis-beta-carotene in vivo. A micellar solution, containing either no addition or 10 mumol of 9-cis- or all-trans-beta-carotene, was perfused for 2 h through the upper portion of the small intestine of ferrets. The effluent of a mesenteric lymph duct cannulation was collected, as well as intestinal mucosa scrapings, a portal blood sample, and a liver biopsy, both before and after perfusion. Carotenoids and retinoids were measured by reverse-phase, high performance liquid chromatography. 9-Cis- and all-trans-beta-carotene were transported equally well into mesenteric lymph, although the intestinal concentration of the corresponding isomer was tenfold higher after perfusion of the 9-cis- isomer than after perfusion of all-trans-beta-carotene. Regardless of which isomer was used, perfusion of beta-carotene resulted in the biosynthesis of similar amounts of retinoic acid in portal blood, liver, and intestine. However, after the perfusion of all-trans-beta-carotene, all the retinoic acid formed was in the all-trans- form, whereas the perfusion of 9-cis-beta-carotene resulted in the biosynthesis of about 50% of the total retinoic acid as the 9-cis-isomer. We conclude that in the in vivo ferret model, 9-cis-beta-carotene has a good bioavailability and is a precursor of 9-cis-retinoic acid.

Background: Inflammatory bowel disease [IBD] is associated with an increased risk of developing lymphoma. Although recent data have clarified the epidemiology of lymphoma in IBD patients, the clinical and pathological characteristics of lymphoma in IBD remain poorly 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 three most frequent lymphoma subtypes occurring in IBD. We performed a multicentre case-control study. Controls [lymphoma de novo] were matched [5:1] to cases on gender, age at diagnosis, lymphoma subtype, year of diagnosis, and IPI/FLIPI indexes. Overall survival and progression-free survival were compared between cases and controls., Results: In total, 133 IBD patients with lymphoma were included [males = 62.4%, median age at lymphoma diagnosis = 49 years in males; 42 years 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]., Conclusions: Lymphomas occurring in IBD patients do not seem to have a worse outcome than in patients without IBD. Due to the rarity of this situation, such patients should be managed in expert centres., (© The Author(s) 2023.

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., (Copyright © 2022 by The American College of Gastroenterology.)

Background and Aims: Patients with inflammatory bowel diseases (IBD) are exposed to drug-related nephrotoxicity and kidney-related extra-intestinal manifestations (EIMs). Patients should be monitored but guidance is lacking in current international recommendations. The objective of the Kidney Function Monitoring in Inflammatory Bowel Disease (MONITORED) initiative was to achieve an expert consensus about monitoring kidney function in IBD., Methods: A literature review was first conducted. Then, an expert consensus meeting, involving 28 attendees representing French-speaking gastroenterologists and nephrologists, was held as part of an academic initiative on May 28, 2021. An anonymous Delphi process was used to discuss and vote on statements. Agreement was defined as at least 75% of participants voting for any one statement., Results: Experts reached consensus on 11 criteria for referral to the nephrologist. Concerning kidney function monitoring, participants unanimously validated the use of serum creatinine with estimation of the glomerular filtration rate via the MDRD or CKD-EPI equations. A blood ionogram and a urine sample with measurement of a protein-to-creatinine ratio were also broadly agreed validated. Experts recommended performing this monitoring at IBD diagnosis, prior introducing a new treatment, and annually for EIMs screening and evaluation of treatment tolerance. An evaluation 3 months after starting mesalamine and then every 6 months was felt necessary, while for biologics an annually monitoring was deemed sufficient., Conclusion: The MONITORED consensus proposed guidelines on how to monitor kidney function in IBD. These recommendations should be considered in clinical practice to preserve kidney function and ensure the best approach to our patients., Competing Interests: Conflict of interest L Guillo declares consulting fees for Abbvie.

Background and Aims: The identification of Crohn's disease (CD)-associated adherent and invasive Escherichia coli (AIEC) is time-consuming and requires ileal biopsies. We aimed to identify a faster and less invasive methods to detect ileal colonization by AIEC in CD patients., Methods: CD patients requiring ileo-colonoscopy were consecutively enrolled in this prospective multicenter study. Samples from saliva, serum, stools, and ileal biopsies of CD patients were collected., Results: Among 102 CD patients, the prevalence of AIEC on ileal biopsies was 24.5%. The abundance and global invasive ability of ileal-associated total E. coli were respectively ten-fold (p = 0.0065) and two-fold (p = 0.0007) higher in AIEC-positive (vs. AIEC-negative), while abundance of total E. coli in the feces was not correlated with AIEC status in the ileum. The best threshold of ileal total E. coli was 60 cfu/biopsy to detect AIEC-positive patients, with high negative predictive value (NPV) (94.1%[80.3-99.3]), while the global invasive ability (>9000 internalized bacteria) was able to detect the presence of AIEC with high positive predictive value (80.0% [55.2-100.0]). Overall, 78.1% of the AIEC + patients were colonized by two or less different AIEC strains. The level of serum anti-total E. coli antibodies (AEcAb) was higher in AIEC-positive patients (p = 0.038) with a very high negative predictive value (96.6% [89.9-100.0]) (p = 0.038) for a cut-off value > 1.9 × 10 -3 ., Conclusions: More than two thirds of AIEC-positive CD patients were colonized by two or less AIEC strains. While stools samples are not accurate to screen AIEC status, the AEcAb level appears to be an attractive, rapid and easier biomarker to identify patients with Crohn's disease harboring AIEC., (© 2021 The Authors.

Introduction: While endoscopic balloon dilation (EBD) is widely used to manage ileal strictures, EBD of colorectal strictures remains poorly investigated in Crohn's disease (CD)., Methods: We performed a retrospective study that included all consecutive CD patients who underwent EBD for native or anastomotic colorectal strictures in 9 tertiary centers between 1999 and 2018. Factors associated with EBD failure were also investigated by logistic regression., Results: Fifty-seven patients (25 women, median age: 36 years (InterQuartile Range, 31-48) were included. Among the 60 strictures, 52 (87%) were native, 39 (65%) measured < 5 cm and the most frequent location was the left colon (27%). Fifty-seven (95%) were non-passable by the scope and 35 (58%) were ulcerated. Among the 161 EBDs performed (median number of dilations per stricture: 2, IQR 1-3), technical and clinical success were achieved for 79% (n = 116/147) and 77% (n = 88/115), respectively. One perforation occurred (0.6% per EDB and 2% per patient). After a median follow-up of 4.3 years (IQR 2.0-8.4), 24 patients (42%) underwent colonic resection and 24 (42%) were asymptomatic without surgery. One colon lymphoma and one colorectal cancer were diagnosed (3.5% of patients) from endoscopic biopsies and at the time of surgery, respectively. No factor was associated with technical or clinical success., Conclusion: EDB of CD-associated colorectal strictures is feasible, efficient and safe, with more than 40% becoming asymptomatic without surgery., (Copyright © 2020.

Background: Preventing postoperative recurrence (POR) is a major concern in Crohn's disease (CD). While azathioprine is an option, no data is available on ustekinumab efficacy in this situation., Aims: We compared the effectiveness of ustekinumab versus azathioprine in preventing endoscopic POR in CD., Methods: We retrospectively collected data from all consecutive CD patients treated with ustekinumab after intestinal resection in 9 centers. The control group (azathioprine alone) was composed of patients who participated in a randomized controlled trial conducted in the same centers comparing azathioprine alone or in combination with curcumin. Propensity score analyses (inversed probability of treatment weighting = IPTW) were applied to compare the two groups. The primary endpoint was endoscopic POR (Rutgeerts' index ≥ i2) at 6 months., Results: Overall, 32 patients were included in the ustekinumab group and 31 in the azathioprine group. The propensity score analysis was adjusted on the main risk factors (smoking, fistulizing phenotype, prior bowel resection, resection length >30 cm and ≥2 biologics before surgery) and thiopurines or ustekinumab exposure prior to surgery making the two arms comparable (∣d∣ < 0.2). After IPTW, the rate of endoscopic POR at 6 months was lower in patients treated with ustekinumab compared to azathioprine (28.0% vs. 54.5%, p = 0.029). After IPTW, the rates of i2b-endoscopic POR (Rutgeerts' index ≥ i2b) and severe endoscopic POR (Rutgeerts' index ≥ i3) were 20.8% versus 42.5% (p = 0.066) and 16.9% versus 27.9% (p = 0.24), in the ustekinumab and azathioprine groups, respectively., Conclusion: Ustekinumab seemed to be more effective than azathioprine in preventing POR in this cohort of CD patients., (© 2021 The Authors.

Background: Abdominal or pelvic radiotherapy in inflammatory bowel disease (IBD) patients raises concerns regarding the risk of worsening of underlying disease., Aim: To assess the impact of radiotherapy on IBD course., Methods: A retrospective multicentre study including IBD patients exposed to abdominal or pelvic irradiation was conducted, retrieving IBD activity by semester (6-month periods) before (from S-4 to S-1) and after (from S + 1 to S + 6) radiotherapy and IBD flare during follow-up., Results: Sixty-one patients (32 women, mean age 59 years), with 467 patient semesters of follow-up, treated for digestive (n = 31), urinary tract (n = 23) and gynaecological cancers (n = 7) were included. Rates of IBD activity per semester were, respectively, 21% (95% CI: 16-27) from S-4 to S-1; 12% (7-19) from S + 1 to S + 3 (P = 0.15 vs S-4 to S-1) and 16% (10-25) from S + 4 to S + 6 (P = 0.45 vs S-4 to S-1). With a median follow-up of 156 weeks (interquartile range: 82-365), rates of survival without IBD flare at 1 and 3 years after radiotherapy were 82.5% (73.2-93.0) and 70.6% (58.8-84.7). Moderate-to-severe acute radiotherapy-induced gut toxicity and the absence of concomitant chemotherapy were independently associated with an increased risk of flare., Conclusion: Most patients with non-active IBD can be safely treated with abdominal or pelvic radiotherapy. Patients having acute gut toxicity and those without concomitant chemotherapy should be more closely monitored in the post-radiotherapy period., (© 2020 John Wiley & Sons Ltd.)

Background: Crohn's disease (CD) is a chronic disorder requiring long-term treatment. However, up to 20% of patients interrupt temporarily or permanently anti-TNFα. Primary aim was to identify internal and external factors influencing patient's motivation to pursue anti-TNFα in active CD., Methods: This was a French, multicentre, prospective study enrolling CD patients on anti-TNFα therapy since more than 3 months. Patients completed the Satisfaction of Patients with Crohn's Disease questionnaire (SPACE-Q) and other patient-reported-outcome tools at inclusion visit, and after 6 and 12 months., Results: A total of 274 patients were included: 146 (53.3%) received adalimumab, while 128 (46.7%) infliximab. Most patients (78%) were still treated with anti-TNFα 12 months after enrolment. Patients' perception of necessity (p = 0.01) and concerns (p<0.0001) regarding medication, evaluated through the Belief about Medicines Questionnaire (BMQ), and expectation confirmation towards treatment convenience (p = 0.02), towards efficacy (p = 0.04), and treatment satisfaction (p = 0.03) according to SPACE-Q, correlated with motivation to pursue treatment. Patients with higher treatment satisfaction (p = 0.0004), stronger belief in treatment necessity (p<0.0001) and fewer concerns (p = 0.0002) were more likely to be very motivated., Conclusion: Treatment satisfaction, treatment necessity, and concerns are correlated to motivation to pursue anti-TNFα. Specific questions focused on these patients' perceptions could help physicians to identify patients at risk of non-adherence and prevent therapy interruption., Competing Interests: Declaration of Competing Interest F.

For inflammatory bowel disease, traditional dose escalation approaches that are based on clinical symptoms are being replaced by more aggressive treat-to-target approaches, in which treatment is adjusted promptly when predefined clinical and mucosal targets are not met. There is, however, an ongoing need to combine up-to-date treat-to-target strategies with easy-to-implement recommendations. Herein, we present consensus-recommendations for treatment targets that reflect current best practices in France. Methods Thirty-four gastroenterologists practicing in France participated in a meeting during which consensus statements about treat-to-target strategies for following patients with Crohn's disease (CD) and ulcerative colitis were developed. Targets, their definitions, and the timeframes for reaching them were defined. Consensus was defined as ≥66% of experts agreeing with a statement. Results For both diseases, the agreed targets were: patient related outcomes on disease (PRO-1), patient related outcomes on gastrointestinal symptoms (PRO-2), endoscopic healing and biomarkers of inflammation. Nutritional status has been defined as a target for CD only. Histological healing and transmural healing were not defined as targets. Deadlines to achieve targets and monitoring frequency have been agreed as well. Conclusions These consensus statements provide simple, easy-to-follow guidelines that should help gastroenterologists in France implement treat-to-target approaches, optimize treatments, and thus, reduce the burden of disease., Competing Interests: Declaration of Competing Interest Guillaume BONNAUD: AbbVie, Alfa Sigma, AMGEN, Bouchara-recordati, Ferring, IPSEN, Janssen, Medtronic, MSD, Mylan, Norgine, Pfizer, Takeda, TILLOTS, Vifor Yoram BOUHNIK: AbbVie, Biogaran, Biogen, Boehringer Ingelheim, Celgene, Ferring, Gilead, Hospira, Janssen, Mayoli Spindler, MSD, Norgine, Pfizer, Roche, Samsung Bioepis, Sandoz, Sanofi, Shire, Takeda, UCB.

Background: Early prediction of postoperative recurrence (POR) remains a major concern in Crohn's disease (CD)., Aims: To assess serial faecal calprotectin (Fcal) monitoring within the first three months to predict CD endoscopic POR., Methods: In a multicenter randomized controlled trial, CD patients received azathioprine 2.5 mg/kg/day with oral curcumin (3 g/day) or placebo. Fcal was measured at baseline, one month (M1) and M3. Endoscopic POR at M6 was defined as Rutgeerts' index ≥ i2b (central reading)., Results: Among the 48 patients included, there was no significant difference of median Fcal levels at baseline (p = 0.15), M1 (p = 0.44) and M3 (p = 0.28) between patients with or without endoscopic POR at M6. Fcal kinetics during the first 3 months after surgery was significantly different between the patients with or without POR at M6 (p = 0.021). The median variation between Fcal level at baseline and M3 (ΔFcal M3-M0) was significantly higher in patients with endoscopic POR compared to those without POR (p = 0.01). ΔFcal M3-M0 >+10% demonstrated the best performances to predict endoscopic POR at M6 (AUC=0.73, sensitivity=64.7%[41.1-82.7], specificity=87.5%[68.0-96.3], negative predictive value=77.8%[57.5-91.4] and positive predictive value=78.6%[49.2-95.3])., Conclusion: Fcal variation within the first three months after ileocolonic resection is a promising predictor of early endoscopic POR in CD patients., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

Background and Aims: Recurrence of Crohn's disease (CD) after surgery is a major concern. Curcumin has anti-inflammatory properties and induces endoscopic remission in patients with ulcerative colitis. We investigated the efficacy of curcumin vs placebo in preventing post-operative recurrence of CD, based on endoscopic and clinical indices, in patients receiving concomitant thiopurine therapy., Methods: We conducted a double-blind randomized controlled trial at 8 referral centers in France, from October 2014 through January 2018, of 62 consecutive patients with CD undergoing bowel resection. Patients received azathioprine (2.5 mg/kg) and were randomly assigned to groups given oral curcumin (3 g/day; n = 31) or an identical placebo (n = 31) for 6 months, and were then evaluated by colonoscopy. We also collected data on CD activity index, results from laboratory tests, and answers to quality of life questionnaires during this 6-month period. The primary endpoint was postoperative recurrence of CD in each group (Rutgeerts' index score ≥i2) at month 6 (determined by central reading). An interim analysis (intent to treat) was scheduled after 50% of the patients were enrolled., Results: At month 6, postoperative recurrence (Rutgeerts' index score ≥i2) occurred in 18 patients (58%) receiving curcumin and 21 patients (68%) receiving placebo (P = .60). A significantly higher proportion of patients receiving curcumin (55%) had a severe recurrence of CD (Rutgeerts' index score ≥i3) than patients receiving placebo (26%) (P = .034). We observed a clinical recurrence of CD (CD activity index score >150) at month 6 in 45% of patients receiving placebo and 30% of patients receiving curcumin (P = .80). Quality of life scores at month 6 did not differ significantly between groups (P = .80). Severe adverse events developed in 6% of patients receiving placebo and 16% of patients receiving curcumin (P = .42)., Conclusions: In a randomized controlled trial of patients who underwent surgery for CD and received thiopurine treatment, we found that curcumin was no more effective than placebo in preventing CD recurrence. There were no significant differences between groups in quality of life or severe adverse events. The study was discontinued after interim analysis due to futility.

Background and Aims: Colon capsule endoscopy (CCE) has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk people. Our aim was to prospectively assess the accuracy of CCE as a screening tool in first-degree relatives (FDRs) of people with CRC by using optical colonoscopy (OC) with segmental unblinding as the reference standard., Methods: Consecutive patients admitted with a CRC diagnosis (index cases) were prospectively evaluated and invited to contact their FDRs. Available FDRs were invited to undergo CCE and OC on the following day, with segmental unblinding of CCE results. Sensitivity, specificity, and predictive values/negative predictive values (PPV/NPV) of CCE were assessed for detecting patients with any polyp ≥6 mm and ≥10 mm., Results: A total of 177 FDRs (median age 57.0 years, 54.8% female) identified from 211 index cases were included. Both CCE and OC were completed in all the included FDRs. Overall, CCE identified 51 of 56 FDRs with polyps ≥6 mm (sensitivity 91%; 95% CI, 81-96) and correctly classified as negative 107 of 121 participants without lesions ≥6 mm (specificity 88%; 95% CI, 81-93). Per-patient positive and negative predictive values for ≥6 mm lesions were 78% (95% CI, 67-87) and 95% (95% CI, 90-98), respectively. CCE detected 24 of 27 patients with polyps ≥10 mm and correctly classified as negative 142 of 150 patients, corresponding to 89% sensitivity and 95% specificity. Post-CCE referral rates to colonoscopy were 37% and 18%, respectively., Conclusions: CCE is an accurate method to screen FDRs of patients with CRC and could be offered as an alternative to those who decline or are unfit for colonoscopy screening.

Objectives: To compare the prevalence of malnutrition and nutritional management between elderly (≥70years old) and younger patients (<70years) with cancer., Patients and Methods: This is a post-hoc analysis of NutriCancer 2012 study; a one-day cross-sectional nationwide survey conducted to assess malnutrition in adult patients with cancer in France. Patients diagnosed with cancer at the study date in both inpatient and outpatient settings were included. Data collection was performed by means of questionnaires completed by the physician, the patient and the caregiver., Results: This post-hoc analysis compared 578 elderly patients (27.6%) vs. 1517 younger patients (72.4%). There were significant differences in cancer localization between the groups particularly in gastrointestinal cancer (27% in younger patients vs. 42% in elderly), breast cancer (17% vs 8% in elderly) and oropharyngeal (15% vs. 9% in elderly). Weight loss was significantly more reported in the elderly than in younger patients (73.6% vs. 67.6%, p=0.009). Elderly patients were more frequently malnourished than younger patients (44.9% vs. 36.7%, p=0.0006). Food intake was comparable between the groups; however, physicians overestimated the food intake, particularly in the elderly. The malnutrition management was more frequently proposed in elderly, as dietary advice and oral nutritional supplements, than in younger patients; however, enteral nutrition was significantly less undertaken in the elderly., Conclusion: Malnutrition is prevalent in elderly patients with cancer, and more frequent than in younger patients. There is a need for an early integration of the nutritional counselling in patients with cancer, and particularly in the elderly., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: The Inflammatory bowel disease (IBD) Disability Index is a validated tool that evaluates functional status; however, it is used mainly in the clinical trial setting. We describe the use of an iterative Delphi consensus process to develop the IBD Disk-a shortened, self-administered adaption of the validated IBD Disability Index-to give immediate visual representation of patient-reported IBD-related disability., Methods: In the preparatory phase, the IBD CONNECT group (30 health care professionals) ranked IBD Disability Index items in the perceived order of importance. The Steering Committee then selected 10 items from the IBD Disability Index to take forward for inclusion in the IBD Disk. In the consensus phase, the items were refined and agreed by the IBD Disk Working Group (14 gastroenterologists) using an online iterative Delphi consensus process. Members could also suggest new element(s) or recommend changes to included elements. The final items for the IBD Disk were agreed in February 2016., Results: After 4 rounds of voting, the following 10 items were agreed for inclusion in the IBD Disk: abdominal pain, body image, education and work, emotions, energy, interpersonal interactions, joint pain, regulating defecation, sexual functions, and sleep. All elements, except sexual functions, were included in the validated IBD Disability Index., Conclusions: The IBD Disk has the potential to be a valuable tool for use at a clinical visit. It can facilitate assessment of inflammatory bowel disease-related disability relevant to both patients and physicians, discussion on specific disability-related issues, and tracking changes in disease burden over time.

Background: Filgotinib (GLPG0634, GS-6034) is a once-daily, orally administered, Janus kinase 1 (JAK1)-selective inhibitor. The FITZROY study examined the efficacy and safety of filgotinib for the treatment of moderate-to-severe Crohn's disease., Methods: We did a randomised, double-blind, placebo-controlled phase 2 study, which recruited patients from 52 centres in nine European countries. We enrolled eligible patients aged 18-75 years with a documented history of ileal, colonic, or ileocolonic Crohn's disease for 3 months or more before screening, as assessed by colonoscopy and supported by histology, and a Crohn's Disease Activity Index (CDAI) score during screening between 220 and 450 inclusive. Patients were randomly assigned (3:1) to receive filgotinib 200 mg once a day or placebo for 10 weeks. Patients were stratified according to previous anti-tumour necrosis factor alpha exposure, C-reactive protein concentration at screening (≤10 mg/L or >10 mg/L), and oral corticosteroid use at baseline, using an interactive web-based response system. The primary endpoint was clinical remission, defined as CDAI less than 150 at week 10. After week 10, patients were assigned based on responder status to filgotinib 100 mg once a day, filgotinib 200 mg once a day, or placebo for an observational period lasting a further 10 weeks. The filgotinib and placebo treatment groups were compared using ANCOVA models and logistic regression models containing baseline values and randomisation stratification factors as fixed effects. Analyses were done on the intention-to-treat non-responder imputation set. The trial was registered at ClinicalTrials.gov, number NCT02048618., Findings: Between Feb 3, 2014, and July 10, 2015, we enrolled 174 patients with active Crohn's disease confirmed by centrally read endoscopy (130 in the filgotinib 200 mg group and 44 in the placebo group). In the intention-to-treat population, 60 (47%) of 128 patients treated with filgotinib 200 mg achieved clinical remission at week 10 versus ten (23%) of 44 patients treated with placebo (difference 24 percentage points [95% CI 9-39], p=0·0077). In a pooled analysis of all periods of filgotinib and placebo exposure over 20 weeks, serious treatment-emergent adverse effects were reported in 14 (9%) of 152 patients treated with filgotinib and three (4%) of 67 patients treated with placebo., Interpretation: Filgotinib induced clinical remission in significantly more patients with active Crohn's disease compared with placebo, and had an acceptable safety profile., Funding: Galapagos., (Copyright © 2017 Elsevier Ltd.

Capsule endoscope aspiration is an increasingly reported complication, potentially responsible for respiratory distress and asphyxia. This adverse event is primarily managed by rigid bronchoscopy when spontaneous expulsion does not occur. This complication is all the more detrimental to patients as it can delay or jeopardize further digestive exploration. We report direct repositioning of the capsule in the stomach at the same time as bronchoscopy, thus making second-line gastrointestinal endoscopy needless., (© 2017 S. Karger AG, Basel.)

Background: Fecal markers might predict the response to anti-TNFα in ulcerative colitis (UC)., Aims: To compare the performance of fecal calprotectin (fCal), lactoferrin (fLact), M2-PK (fM2-PK), neopterin (fNeo), and zonulin (fZon) to predict the response to therapy in active UC patients., Methods: Disease activity from 31 consecutive patients with an active UC, treated with infliximab (IFX) was assessed by the Mayo score at baseline and at week 14 and by the partial Mayo score at W52 and stool samples collected for fecal marker measurements at W0, W2, and W14., Results: At W14, 19 patients (61%) were responders to IFX induction. The median levels of fCal, fLact and fM2-PK drop dramatically from baseline to W14 in clinical responders. At W2, fM2-PK, fLact and fCal levels predicted accurately the response to IFX induction. At W14, fLact, fCal, and fM2-PK were individually reliable markers to predict sustained response at W52. The performances of fNeo and fZon were weaker in this setting., Conclusions: The performance of fM2-PK at W2 to predict response to induction therapy with IFX was superior to that of fLact and fCal, whereas monitoring fLact was the best tool to predict adequately the course of the disease at one year under maintenance IFX in UC., (Copyright © 2016.

Background: Recently, treatment algorithms were developed in France additionally to ECCO recommendations that should be used as reference for ulcerative colitis (UC) management. Nevertheless, their implementation in clinical practice remains challenging., Aims: To evaluate the prevalence of the use of these UC management algorithms in 127 patients followed by private gastroenterologists., Methods: Charts of all UC patients seen during the year 2015 (n=127) by 10 gastroenterologists were reviewed. The gastroenterologist's management was then compared to the corresponding algorithm situation and, in case of disagreement, analysed by an expert committee., Results: 94.5% of patients corresponded to a clinical situation described in algorithms. Gastroenterologist's management was adequate to the corresponding algorithm situation in 74.2% of cases. Among the 31 cases of disagreement, the gastroenterologist's decision differed from the algorithm position in 21 cases, and in 76.2% of cases the expert committee would have made the same decision. In the remaining 10 cases, the decision differed from the corresponding algorithm for reasons independent from the gastroenterologist (patient's choice etc.)., Conclusions: French national algorithms for UC management allowed coverage of 95% of clinical cases in real world. In three quarters of cases, these algorithms were strictly followed by private gastroenterologists. Dissemination of these algorithms could optimize and strengthen the practitioner's choice., (Copyright © 2016 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.
