1. Prevalence of the Oral Corticosteroid Exposure and Excessive Use in Patients with Inflammatory Bowel Disease: Data from Four French Referral Centers of the International DICE Study

Author: Stéphane Nancey, Xavier Hébuterne, Cyrielle Gilletta, Evguenia Hacques, and Xavier Roblin
Subjects: corticosteroids, Crohn’s disease, inflammatory bowel disease, ulcerative colitis, Medicine
Abstract: Background: Corticosteroids used to induce a response in Crohn’s disease (CD) and ulcerative colitis (UC) may cause adverse reactions. The DICE study aimed to quantify and investigate factors associated with their use. Methods: This cross-sectional, non-interventional study conducted in seven countries allowed us to collect data on oral corticosteroid exposure and excessive use (cf. British Society of Gastroenterology) over the past 12 months in adult patients with CD or UC for more than a year. The factors associated with these practices were investigated using marginal logistic models. We present the results from the four participating French expert centers. Results: Corticosteroid exposure over the past 12 months was observed in 20.1% of 324 CD patients and 30.2% of 205 UC patients. Excessive use was reported in 13.3% and 17.1% of patients, respectively. Corticosteroid exposure and excessive use were less frequently observed in CD than in UC (OR: 0.56, p < 0.0001, and 0.69, p = 0.0042). A disease activity assessment at patient’s last visit was the main factor (p < 0.01) associated with the risk of corticosteroid exposure and excessive use in CD (OR: 3.41 and 3.44) and UC (OR: 7.29 and 6.90). Conclusions: Corticosteroid exposure and excessive use continue to be frequently observed in CD and UC in France.

Subjects: Crohn’s disease, ulcerative colitis, infliximab, vedolizumab, SARS-CoV-2, trough levels, Immunologic diseases. Allergy, RC581-607
Abstract: BackgroundPatients with inflammatory bowel disease (IBD) may have a modified immune response to SARS-CoV-2. The objectives were to evaluate the prevalence of COVID-19 in patients treated with infliximab or vedolizumab, to analyze the factors associated with the infection, the impact of treatments and trough levels.MethodsPatients with IBD treated with intravenous biologics in 14 French centers were included between March and June 2020 and followed-up for 6 months. Blood samples were collected for serologies and trough levels. The analysis of factors associated with COVID-19 was conducted in a matched 1:1 case-control sub-study with positive patients.ResultsIn total, 1026 patients were included (74.9% infliximab). Over the follow-up period, 420 patients reported the occurrence of COVID-19 symptoms; 342 had been tested of whom 18 were positive. At the end of follow-up, 38 patients had a positive serology. Considering both nasal tests and serologies together, 46 patients (4.5%) had been infected. The risk of COVID-19 was related neither to the use of treatments (whatever the trough levels) nor to disease activity. Infections were more frequent when using public transport or living in flats in urban areas.ConclusionsThe prevalence rate of COVID-19 in this IBD population treated with intravenous infliximab or vedolizumab was the same as the one in the French population before the start of the vaccination campaign. The risk was increased by urban living and was not influenced by disease activity or biologics. Sanitary barrier measures remain the best way to protect against SARS-CoV-2 in patients with IBD in biological therapy.

3. Serum calprotectin is useful to confirm inflammatory bowel disease activity but not to predict relapse

Author: Pauline Veyrard, Xavier Roblin, Céline Pansart, Ren Mao, Stéphane Nancey, Martin Killian, Louis Waeckel, Anne-Emmanuelle Berger, Nicolas Williet, Laetitia Bastide, Mathilde Barrau, Quentin Tournier, and Stéphane Paul
Subjects: Serum calprotectin, Inflammatory bowel diseases, Crohn's disease, Ulcerative colitis, Relapse, Mucosal healing, Immunologic diseases. Allergy, RC581-607
Abstract: Aim: Serum calprotectin (SC), a novel biomarker of inflammatory bowel diseases (IBD), has been recently investigated with conflicting results. The purpose of this study was to assess the ability of SC to predict relapse in IBD patients treated by biologic therapies, and to evaluate the correlation between SC, clinical and endoscopic relapse and other biomarkers as fecal calprotectin (FC) and C-reactive protein (CRP). Methods: All consecutive IBD patients in deep remission (clinical, endoscopic or imaging remission) were followed 12 months in this prospective study. Blood and stool samples were collected for SC, serum CRP and FC. SC was measured the day of inclusion (baseline, D0), 3 months (M3) and at 6 months (M6) or during the study period for clinical relapse. Relapse was defined as clinical, biomarkers, or endoscopic/imaging activities. Evolution of SC was quantified before relapse to analyze a predicting value of loss of response (LOR). SC for patients with active IBD and those with symptoms without inflammation were also compared. Results: Among the 119 patients included, 54 (46.4%) patients experienced a disease relapse during follow-up. Median SC levels did not increase in patients with clinical relapse (3.15 µg/ml at baseline, 3.38 µg/ml at M3, 3.33 µg/ml at M6 and 3.99 µg/ml in case of relapse (p = 0.63)). SC were compared during relapse in patients with endoscopic remission but clinical symptoms defined as secondary Irritable Bowel Syndrome (IBS). SC levels were higher in active IBD and similar between the groups of patients with IBS or deep remission (3.05 µg/ml IBS vs 2.99 µg/ml remission vs 5.1 µg/ml for clinical relapse, p = 0.04). In patients with clinical symptoms, SC presents a good predictive value for relapse (AUROC 0.764, IC95: 0.68–0.88), with a sensitivity of 72%, a specificity of 77%, using a cut-off value of 4.45 µg/ml. A weak, but significant correlation was found between SC and FC levels (r = 0.35, P = 0.001). A combined score with CRP, FC and SC is not efficient to improve IBD diagnostic. Conclusion: SC was significantly higher in patients with clinical relapse compared to those with endoscopic remission with or without clinical symptoms. SC allow to discriminate patients with active IBD or with IBS but failed to predict relapse.

4. What Should We Know about Drug Levels and Therapeutic Drug Monitoring during Pregnancy and Breastfeeding in Inflammatory Bowel Disease under Biologic Therapy?

Author: Mathilde Barrau, Xavier Roblin, Leslie Andromaque, Aurore Rozieres, Mathias Faure, Stéphane Paul, and Stéphane Nancey
Subjects: therapeutic drug monitoring, pregnancy, breastfeeding, inflammatory bowel disease, Medicine
Abstract: Data on the real long-term influences of in utero drug exposure in pregnant women on childhood development are scarce and remain not well determined and depend on the duration of in utero drug exposure and maternal drug levels. Therapeutic drug monitoring (TDM) during pregnancy may help limit fetal drug exposure while maintaining an effective dose for the treatment of the underlying inflammatory bowel disease (IBD) in women. Most antibody therapies used in patients with IBD are IgG molecules which are actively transported across the placenta, especially during the third trimester of the pregnancy. Here, we propose an up-to-date clinical review to summarize the available findings of serum drug levels in maternal blood during pregnancy, in the cord blood, infants at delivery and in breast milk of patients with IBD treated with biologics. Conversely, in comparison to adalimumab (ADA) levels, which are relatively stable during pregnancy, infliximab (IFX) drug clearance decreased significantly during the last two trimesters of the pregnancy, leading to increasing drug concentrations in the blood of the pregnant women. As most guidelines recommend using live vaccines in infants at the age of one or earlier in case of negative serum drug levels in newborns, statistical models could help clinicians in making a decision to adjust the last dose of the biologic during pregnancy and to determine the optimal date to vaccinate. Altogether, data from the literature offers strong reassurance in terms of safety for anti-TNFα therapies during pregnancy not only for IBD patients who intend to conceive, but also for pregnant women and for the physicians taking care of these patients. ADA and IFX levels in breast milk are detectable, but at very low levels, and therefore, it is recommended to pursue breast feeding under anti-TNFα therapy. Our knowledge on ustekinumab or vedolizumab levels in pregnant women remains unclear and scarce. These drugs are currently not recommended for patients with IBD in clinical practice. Therefore, TDM and proactive dose adjustment are not necessary during pregnancy since its impact on making a clinical decision have not yet been clearly demonstrated in routine practice. Overall, drug concentrations in the cord blood, an infant at birth and postpartum serum concentrations in infants, due to active placental drug transfer, may have a greater impact than the limited drug transfer in breast milk during lactation on the risk of infection and developmental outcomes. Ustekinumab and vedolizumab exposure during pregnancy and lactation are both considered low risk by the recent ECCO guidelines despite the limited data that are currently available.

5. Use of imaging modalities for decision-making in inflammatory bowel disease

Author: Stéphane Nancey, Mathurin Fumery, Mathias Faure, Gilles Boschetti, Claire Gay, Laurent Milot, and Xavier Roblin
Subjects: Diseases of the digestive system. Gastroenterology, RC799-869
Abstract: Cross-sectional magnetic resonance enterography (MRE) and intestinal ultrasonography (IUS) provide valuable and noninvasive information to accurately assess disease activity, severity, and extent; detect complications; and monitor the response to treatment, as well as predict the postoperative recurrence of Crohn’s disease and a negative disease course. Therefore, both imaging modalities are emerging as pivotal diagnostic tools to achieve the emerging therapeutic target of transmural healing associated with better disease outcomes. Despite its numerous potential advantages over endoscopy and even MRE and its good availability, IUS is still widely underused to monitor and manage inflammatory bowel disease (IBD) patients and help in making clinical decisions in routine practice. This situation is clearly due to the absence of validated, reliable, and responsive indices, as well as the lack of trained gastroenterologists and radiologists, as IUS is a component of radiologist expertise in several countries but not yet integrated into the training program of gastroenterologists. However, there is an increasing body of evidence in the literature that IUS and MRE are both becoming essential imaging resources to help clinicians in making reliable decisions. Here, we discuss the up-to-date evidence about the usefulness and performance of cross-sectional imaging, focusing on the ability of bowel US and MRE to aid clinical decision-making for the optimal management and monitoring of IBD.

Author: Aonghus Lavelle, Stéphane Nancey, Jean-Marie Reimund, David Laharie, Philippe Marteau, Xavier Treton, Matthieu Allez, Xavier Roblin, Georgia Malamut, Cyriane Oeuvray, Nathalie Rolhion, Xavier Dray, Dominique Rainteau, Antonin Lamaziere, Emilie Gauliard, Julien Kirchgesner, Laurent Beaugerie, Philippe Seksik, Laurent Peyrin-Biroulet, and Harry Sokol
Subjects: Gut microbiota, inflammatory bowel disease, dysplasia, colitis-associated colorectal cancer, crohn’s disease, ulcerative colitis, Diseases of the digestive system. Gastroenterology, RC799-869
Abstract: Due to the potential role of the gut microbiota and bile acids in the pathogenesis of both inflammatory bowel disease (IBD) and sporadic colorectal cancer, we aimed to determine whether these factors were associated with colorectal cancer in IBD patients. 215 IBD patients and 51 non-IBD control subjects were enrolled from 10 French IBD centers between September 2011 and July 2018. Fecal samples were processed for bacterial 16S rRNA gene sequencing and bile acid profiling. Demographic, clinical, endoscopic, and histological outcomes were recorded. Characteristics of IBD patients included: median age: 41.6 (IQR 22); disease duration 13.2 (13.1); 47% female; 21.9% primary sclerosing cholangitis; 109 patients with Crohn’s disease (CD); 106 patients with ulcerative colitis (UC). The prevalence of cancer was 2.8% (6/215: 1 CD; 5 UC), high-grade dysplasia 3.7% (8/215) and low-grade dysplasia 7.9% (17/215). Lachnospira was decreased in IBD patients with cancer, while Agathobacter was decreased and Escherichia-Shigella increased in UC patients with any neoplasia. Bile acids were not associated with cancer or neoplasia. Unsupervised clustering identified three gut microbiota clusters in IBD patients associated with bile acid composition and clinical features, including a higher risk of neoplasia in UC in two clusters when compared to the third (relative risk (RR) 4.07 (95% CI 1.6–10.3, P

Subjects: Crohn’s disease, CD4+ T cells, FOXP3, interleukin 17A, relapse, Immunologic diseases. Allergy, RC581-607
Abstract: Background and aimsWe aimed to analyze circulating CD4+ T cell subsets and cytokines during the course of Crohn’s disease (CD).Methods and resultsCD4+ T cell subsets, ultrasensitive C-reactive protein (usCRP), and various serum cytokines (IL-6, IL-8, IL-10, IL-13, IL-17A, IL-23, TNFα, IFNγ, and TGFβ) were prospectively monitored every 3 months for 1 year, using multicolor flow cytometry and an ultrasensitive Erenna method in CD patients in remission at inclusion. Relapse occurred in 35 out of the 113 consecutive patients (31%). For patients in remission within 4 months prior to relapse and at the time of relapse, there was no significant difference in Th1, Th17, Treg, and double-positive CD4+ T cell subsets co-expressing either IFNγ and FOXP3, IL-17A and FOXP3, or IFNγ and IL-17A. On the contrary, in patients who remained in remission, the mean frequency and number of double-positive IL-17A+FOXP3+ CD4+ T cells and the level of usCRP were significantly higher (p ≤ 0.01) 1 to 4 months prior to relapse. At the time of relapse, only the IL-6 and usCRP levels were significantly higher (p ≤ 0.001) compared with those patients in remission. On multivariate analysis, a high number of double-positive IL-17A+FOXP3+ CD4+ T cells (≥1.4 cells/mm3) and elevated serum usCRP (≥3.44 mg/L) were two independent factors associated with risk of relapse.ConclusionsDetection of circulating double-positive FOXP3+IL-17A+ CD4+ T cell subsets supports that T cell plasticity may reflect the inflammatory context of Crohn’s disease. Whether this subset contributes to the pathogenesis of CD relapse needs further studies.

8. Regulation of anti-microbial autophagy by factors of the complement system

Author: Christophe Viret, Aurore Rozières, Rémi Duclaux-Loras, Gilles Boschetti, Stéphane Nancey, and Mathias Faure
Subjects: autophagy, complement, immunity, infection, bacteria, virus, homeostasis, Biology (General), QH301-705.5
Abstract: The complement system is a major component of innate immunity that participates in the defense of the host against a myriad of pathogenic microorganisms. Activation of complement allows for both local inflammatory response and physical elimination of microbes through phagocytosis or lysis. The system is highly efficient and is therefore finely regulated. In addition to these well-established properties, recent works have revealed that components of the complement system can be involved in a variety of other functions including in autophagy, the conserved mechanism that allows for the targeting and degradation of cytosolic materials by the lysosomal pathway after confining them into specialized organelles called autophagosomes. Besides impacting cell death, development or metabolism, the complement factors-autophagy connection can greatly modulate the cell autonomous, anti-microbial activity of autophagy: xenophagy. Both surface receptor-ligand interactions and intracellular interactions are involved in the modulation of the autophagic response to intracellular microbes by complement factors. Here, we review works that relate to the recently discovered connections between factors of the complement system and the functioning of autophagy in the context of host-pathogen relationship.

9. The Kynurenine Pathway and Cancer: Why Keep It Simple When You Can Make It Complicated

Subjects: NAD, kynurenine, tumor initiation and progression, Neoplasms. Tumors. Oncology. Including cancer and carcinogens, RC254-282
Abstract: The kynurenine pathway has been highlighted as a gatekeeper of immune-privileged sites through its ability to generate from tryptophan a set of immunosuppressive metabolic intermediates. It additionally constitutes an important source of cellular NAD+ for the organism. Hijacking of its immunosuppressive functions, as recurrently observed in multiple cancers, facilitates immune evasion and promotes tumor development. Based on these observations, researchers have focused on characterizing indoleamine 2,3-dioxygenase (IDO1), the main enzyme catalyzing the first and limiting step of the pathway, and on developing therapies targeting it. Unfortunately, clinical trials studying IDO1 inhibitors have thus far not met expectations, highlighting the need to unravel this complex signaling pathway further. Recent advances demonstrate that these metabolites additionally promote tumor growth, metastatic dissemination and chemoresistance by a combination of paracrine and autocrine effects. Production of NAD+ also contributes to cancer progression by providing cancer cells with enhanced plasticity, invasive properties and chemoresistance. A comprehensive survey of this complexity is challenging but necessary to achieve medical success.

10. Toll-Interacting Protein Regulates Immune Cell Infiltration and Promotes Colitis-Associated Cancer

Author: Christina Begka, Céline Pattaroni, Catherine Mooser, Stéphane Nancey, Kathy D. McCoy, Dominique Velin, and Michel H. Maillard
Subjects: Science
Abstract: Summary: Expression of Toll-interacting protein (Tollip), a potent TLR modulator, decreases in patients with inflammatory bowel diseases (IBD), whereas Tollip−/− mice are susceptible to colitis. Tollip expression was shown to be reduced in sporadic adenoma. In contrast, we found variable Tollip expression in patients with colitis-associated adenomas. In Tollip−/− mice challenged to develop colitis-associated cancer (CAC), tumor formation was significantly reduced owing to decreased mucosal proliferative and apoptotic indexes. This protection was associated with blunt inflammatory responses without significant changes in microbial composition. mRNA expression of Cd62l and Ccr5 homing receptors was reduced in colons of untreated Tollip−/− mice, whereas CD62L+ CD8+ T cells accumulated in the periphery. In Tollip-deficient adenomas Ctla-4 mRNA expression and tumor-infiltrating CD4+ Foxp3+ regulatory T cell (Treg) were decreased. Our data show that protection from CAC in Tollip-deficient mice is associated with defects in lymphocyte accumulation and composition in colitis-associated adenomas. : Biological Sciences; Immunology; Cancer Subject Areas: Biological Sciences, Immunology, Cancer

Abstract: Yersinia are common contaminants of food products, but their prevalence in the human gut is poorly documented. Yersinia have been implicated in Crohn's Disease (CD, an inflammatory bowel disease) however their role in CD is controversial. We performed highly sensitive PCR assays of specific sequences for the gyrB gene of Y. aldovae, Y. bercovieri, Y. enterocolitica, Y. intermedia, Y. mollaretii and the inv gene of Y. pseudotuberculosis. We analyzed a total of 470 ileal samples taken from 338 participants (262 CD patients and 76 controls) belonging to three independent cohorts. All patients and controls were phenotyped and genotyped for the main CD susceptibility variants: NOD2, ATG16L1, and IRGM. Yersinia were found in 7.7% of ileal samples (respectively 7.9 and 7.6% in controls and CD patients) corresponding to 10% of participants (respectively 11.8 and 9.5% in controls and CD patients). Y. enterocolitica, Y. pseudotuberculosis and Y. intermedia were the most frequently identified species. The bacteria were more frequent in resected specimens, lymph nodes and Peyer's patches. Yersinia were no more likely to be detected in CD tissues than tissues from inflammatory and non-inflammatory controls. CD patients treated with immunosuppressants were less likely to be Yersinia carriers. In conclusion, this work shows that Yersinia species are frequently found at low levels in the human ileum in health and disease. The role of Yersinia species in this ecosystem should now be explored.

12. Oral probiotic control skin inflammation by acting on both effector and regulatory T cells.

Subjects: Medicine, Science
Abstract: Probiotics are believed to alleviate allergic and inflammatory skin disorders, but their impact on pathogenic effector T cells remains poorly documented. Here we show that oral treatment with the probiotic bacteria L. casei (DN-114 001) alone alleviates antigen-specific skin inflammation mediated by either protein-specific CD4(+) T cells or hapten-specific CD8(+) T cells. In the model of CD8(+) T cell-mediated skin inflammation, which reproduces allergic contact dermatitis in human, inhibition of skin inflammation by L. casei is not due to impaired priming of hapten-specific IFNgamma-producing cytolytic CD8(+) effector T cells. Alternatively, L. casei treatment reduces the recruitment of CD8(+) effector T cells into the skin during the elicitation (i.e. symptomatic) phase of CHS. Inhibition of skin inflammation by L. casei requires MHC class II-restricted CD4(+) T cells but not CD1d-restricted NK-T cells. L casei treatment enhanced the frequency of FoxP3(+) Treg in the skin and increased the production of IL-10 by CD4(+)CD25(+) regulatory T cells in skin draining lymph nodes of hapten-sensitized mice. These data demonstrate that orally administered L. casei (DN-114 001) efficiently alleviate T cell-mediated skin inflammation without causing immune suppression, via mechanisms that include control of CD8(+) effector T cells and involve regulatory CD4(+) T cells. L. casei (DN-114 001) may thus represent a probiotic of potential interest for immunomodulation of T cell-mediated allergic skin diseases in human.

Abstract: International audience; BACKGROUND: Use of a combination of targeted therapies (COMBIO) in patients with refractory/overlapping immune-mediated inflammatory diseases (IMIDs) has increased, but reported data remain scarce. We aimed to assess effectiveness and safety of COMBIO in patients with IMIDs. METHODS: We conducted a French ambispective multicenter cohort study from September 2020 to May 2021, including adults' patients with 1 or 2 IMIDs and treated at least 3-month with COMBIO. RESULTS: Overall, 143 patients were included. The most common IMIDs were Crohn's disease (63.6%), axial spondyloarthritis (37.7%), and ulcerative colitis (14%). Half of patients had only one IMID, of which 60% were Crohn's disease. Mean duration of COMBIO was 274.5±59.3 weeks, and COMBIO persistence at 104 weeks was estimated at 64.1%. The most frequent COMBIOs combined anti-TNF agents with vedolizumab (30%) or ustekinumab (28.7%). Overall, 50% of patients achieved significant and 27% mild-to-moderate improvement in patient-reported outcomes. Extended duration of COMBIO (aOR=1.09; 95% CI: 1.03-1.14; p=0.002) and diagnoses of two IMIDs (aOR=3.46; 95%CI: 1.29-9.26; p=0.013) were associated with significant improvement in patient-reported outcomes. Incidence of serious infection during COMBIO was 4.51 per 100 person-years (95% CI 2.20-8.27) and 5 COMBIOs were discontinued due to adverse events. CONCLUSIONS: COMBIO can be effective and safe in patients with refractory/overlapping IMIDs.

Abstract: Introduction: Loss of response to golimumab occurs in nearly 40% of patients with ulcerative colitis (UC). Unlike others anti-TNF, no study has reported a correlation between serum golimumab level and response to drug intensification. The objective of this study was to evaluate the effectiveness and safety of golimumab intensification and to identify the best threshold of serum golimumab before drug intensification predictive of response.Patients and methods: We included all consecutive patients with active UC with loss of response to golimumab in a prospective multicentric cohort study. Patients with loss of response at 50 mg q4 weeks (W) and 100 mg q4W underwent therapeutic intensification at 100 mg q4W and 100 mg q2W, respectively. Effectiveness and safety were assessed between Weeks 2 and 4 (visit 2) and between Weeks 4 and 8 (visit 3) after intensification. Serum level and anti-golimumab antibodies were evaluated at each medical visit (Lisa Tracker, Theradiag France).Results: A total of 47 UC patients (Female, 50%; median age, 39 years (IQR, 27-52)) treated with golimumab for a median of 20.4 weeks (IQR, 10.7-38.3) were included. The median partial Mayo score was 6 (IQR, 5-7), and the median endoscopic Mayo score was 3 (IQR, 2-3). The median golimumab serum level before intensification was 2.23 μg/mL (IQR, 1.02-3.96) and only one patient (2.1%) had anti-drug antibodies. At Visit 2 (Week 2-4), 40% patients experienced clinical response, 10% clinical remission, 33% endoscopic response and 23% endoscopic remission. At Visit 3 (Week 4-8), 44% of patients had clinical response, 22% of patients had clinical remission, 45% of patients had endoscopic response, and 41% of patients had endoscopic remission. The median golimumab levels before intensification do not differ between responders and non-responders (2.13 μg/ml (0.76-2.76) and 3.37 μg/ml (IQR, 1.08-4.67), respectively; p = 0.14) assessed at Visit 3. Golimumab intensification to 100 mg q4W (vs q2W) (OR 1.98, 95% CI [1.06-3.70]; p = 0.032) was significantly associated with clinical remission at Visit 3. Serum drug level at baseline or the presence of antidrug antibodies were not associated with clinical or endoscopic remission/response. Two serious adverse events (one infection and one UC flare) were reported during the 24-week follow-up.Conclusion: In this prospective multicentric study, half of patients recaptured response following golimumab intensification in UC. Therapeutic drug monitoring did not predict response after optimisation of golimumab.

Abstract: International audience; 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 CD patients 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 CD patients with resolved intra-abdominal abscess treated with ADA with a two-year follow-up. The primary endpoint was ADA failure at W24 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 (50%) patients were male and the median age at baseline was 28 years. At W24, 87 (74%, 95%CI: 65.5-82.0, n=117) patients 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 (OR=4.18; 95%CI: 1.06-16.5; p=0.043). Disease duration (HR=1.32, 95%CI: 1.09-1.59, p=0.008), abscess drainage (HR=5.59, 95%CI: 2.21-14.15, p=0.001), and inflammatory changes in mesenteric fat (HR=0.4, 95%CI: 0.17-0.94, p=0.046) 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.

Abstract: International audience; Background and AimsThe 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.MethodsCD 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.ResultsAmong 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.ConclusionsMore 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.

Abstract: Objective The association of IgA vasculitis (IgAV) and IBD is rarely described, mainly during anti-TNF-α therapy. We aimed to describe the association of IgAV and IBD. Methods We retrospectively analysed the association of IgAV and IBD through the implication of the GETAID and FVSG networks. Characteristics of IBD and IgAV were collected using a standardized case report form. Results Forty-three cases were included. IBD [mainly Crohn’s disease (CD) in 58%] preceded IgAV in 38 (88%), with median interval of 9.2 (IQR 5.4–15.4) years. In these 38 patients, at IgAV diagnosis, five (13%) had active IBD and 28 (74%) were treated with anti-TNF-α for a median duration of 31.5 (IQR 19–56) months. Main IgAV manifestations were purpura all patients (100%), joints in 20/35 (57%), renal in 15/35 (43%) and gastrointestinal in 11/35 (31%) involvement. IgAV was treated with glucocorticoids in 25 (66%), colchicine in six (16%), CYC in six (16%) and anti-TNF-α were discontinued in 15/28 (54%). No IgAV relapse occurred when TNF-α blockers were stopped, vs 23% in patients pursuing it. Conversely, five (33%) had IBD flare or complication after anti-TNF-α cessation vs one (8%) in those continuing biologics. Anti-TNF-α were resumed in six (40%), with subsequent IgAV relapse in four (67%). Conclusions This large cohort suggests that TNF-α blockers may promote the onset of IgAV in IBD. Discontinuation of anti-TNF-α was associated with vasculitis remission but increased risk of IBD relapses, whereas continuation of anti-TNF-α was associated with IBD remission but vasculitis relapse.

Abstract: Background In cases of loss of response due to mechanistic failure under antitumor necrosis factor agents, it is recommended to switch to another class of biologics. Two different strategies were compared in patients with inflammatory bowel disease (IBD) who were treated with nonoptimized adalimumab (ADA) and experienced a loss of response despite therapeutic trough levels of adalimuma—either ADA dose optimization or switching to vedolizumab or ustekinumab. Methods Patients under maintenance therapy with ADA monotherapy (40 mg every 14 days) and who experienced a secondary loss of response with trough levels > 4.9 μg/mL were included prospectively in this nonrandomized study. The primary end point was the survival rate without therapeutic discontinuation after ADA dose optimization or switching to another class of biologics. Results Adalimumab was optimized (n = 61 patients, 42 Crohn’s disease, 19 ulcerative colitis) or swapped for vedolizumab (n = 40, 20 ulcerative colitis) or ustekinumab (n = 30, 30 Crohn’s disease). At 24 months, 11 out of 70 patients (14.8%) in the swap group discontinued treatment compared with 36 out of 61 (59.6%) patients in the optimization group (P 24 months) than in the optimization group (13.3 months, P 500 μg/g (HR, 3.53; 95% CI, 1.16–10.72; P = 0.026) and inversely associated with variation of trough levels of adalimumab (>2 µg/mL from baseline to week 8 after optimization; HR, 0.51; 95% CI, 0.13–0.82; P = 0.03). In the swap group, no factor was associated with treatment discontinuation. Conclusion In IBD patients under ADA maintenance therapy who experience a secondary loss of response and in whom trough levels are >4.9µg/mL, swapping to another class is better than optimizing ADA, which is, however, appropriate in a subgroup of patients.

Abstract: Background and Aims Defining and assessing the reproducibility of Crohn’s disease [CD] endoscopic lesions is essential in assessing endoscopic healing. Methods Twelve endoscopic CD experts from the GETAID defined aphthoid erosions [AE], superficial ulcerations [SU], deep ulcerations [DU], stenosis, and fistulas according to a Delphi-like method. Thirty different GETAID physicians declared if they found acceptable each definition. Intra- and inter-observer agreements were investigated using 100 videos with one tagged specific lesion [AE, SU, DU, or sham lesion] read by 15 independent endoscopists at baseline and 1 month later in a randomised order. Video quality was determined by an external reader. According to kappa estimate [κ ±standard error], intra or inter-observer agreement was qualified as ‘moderate’ [0.4–0.6], ‘substantial’ [0.6–0.8], or ‘almost perfect’ [0.8–1.0]. Results Among 30 different experts, 83% to 97% found acceptable the definitions retrieved from the Delphi-like method. Intra-observer κ was 0.717 [±0.019] for SU, 0.681 [±0.027] for AE, 0.856 [±0.014] for DU, showing ‘substantial’ agreement. It was 0.801 [±0.016] for any ulceration [DU or SU]. There was a high variability across readers from ‘moderate’ to ‘almost perfect’ agreement. Inter-observer κ was 0.548 [±0.042] for SU, 0.554 [±0.028] for AE 0.694 [±0.041] for DU, and 0.705 [±0.042] for any ulceration. Inter-observer agreement increased when reading the 53 high-quality videos: 0.787 [±0.064] [p = 0.001], 0.607 [±0.043] [p = 0.001], and 0.782 [±0.064][p = 0.001] for DU, AE, and any ulceration, respectively. Conclusions Despite variable intra-agreement level across readers, the GETAID definitions for CD endoscopic lesions provided ‘substantial’ inter-observer agreements, especially in case of high-quality videos.

Abstract: Background: Several adalimumab preparations are now available for patients with inflammatory bowel disease (IBD). Comparative satisfaction and tolerability are unknown. Objectives: This study investigated IBD patient satisfaction with approved adalimumab biosimilars and their originator. Design: In this cross-sectional study, we included 941 consecutive adalimumab-treated patients with IBD across 45 centres affiliated with the Groupe d’Etude Therapeutique des Affections Inflammatoires du tube Digestif who completed a satisfaction questionnaire comprising four items each rated by a 10-point scale. Methods: The differences in responses were performed using a one-way analysis of variance followed by Tukey’s honest significant difference test.

Abstract: The pharmacokinetic equivalence of dose intensification with adalimumab (ADA) 80 mg every other week (EOW) compared to weekly 40 mg has only been supported by modeling systems. To compare the trough levels of ADA (TLA) and the occurrence of anti-ADA antibodies (AAA) between these two treatment regimens. This was a prospective study including all consecutive patients with inflammatory bowel disease (IBD) who had reached a longstanding and deep remission under treatment with ADA 40 mg once a week. In these patients, the ADA regimen was changed from 40 mg/week to 80 mg EOW. TLA and AAA levels using a drug-tolerant assay were monitored before and ten weeks after from the change in the ADA regimen and the results compared by a Wilcoxon paired test. Sixty-two patients (60% CD, mean age 35 years) were included. Before and ten weeks after the changes of ADA regimen, the median TLA were (6.9 µg/mL versus 7.0 µg/mL, respectively; P = 0.34) and the AAA levels (3.4 µg/ml-eq versus 3.0 µg/ml-eq, respectively; P = 0.25.) were quite similar.

Abstract: Background The approved maintenance regimens for ustekinumab in Crohn’s disease [CD] are 90 mg every 8 or 12 weeks. Some patients will respond partially to ustekinumab or will experience a secondary loss of response. It remains poorly known if these patients may benefit from shortening the interval between injections. Methods All patients with active CD, as defined by Harvey–Bradshaw score ≥ 4 and one objective sign of inflammation [C-reactive protein > 5 mg/L and/or faecal calprotectin > 250 µg/g and/or radiological and/or endoscopic evidence of disease activity] who required ustekinumab dose escalation to 90 mg every 4 weeks for loss of response or incomplete response to ustekinumab 90 mg every 8 weeks were included in this retrospective multicentre cohort study. Results One hundred patients, with a median age of 35 years [interquartile range, 28–49] and median disease duration of 12 [7–20] years were included. Dose intensification was performed after a median of 5.0 [2.8–9.0] months of ustekinumab treatment and was associated with corticosteroids and immunosuppressants in respectively 29% and 27% of cases. Short-term clinical response and clinical remission were observed in respectively 61% and 31% after a median of 2.4 [1.3–3.0] months. After a median follow-up of 8.2 [5.6–12.4] months, 61% of patients were still treated with ustekinumab, and 26% were in steroid-free clinical remission. Among the 39 patients with colonoscopy during follow-up, 14 achieved endoscopic remission [no ulcers]. At the end of follow-up, 27% of patients were hospitalized, and 19% underwent intestinal resection surgery. Adverse events were reported in 12% of patients, including five serious adverse events. Conclusion In this multicentre study, two-thirds of patients recaptured response following treatment intensification with ustekinumab 90 mg every 4 weeks.

Abstract: BACKGROUND AND AIMS: Crohn’s disease (CD) frequently affects young women and may require surgery during pregnancy. Data regarding operation for CD in expectant mothers are scare. MATERIALS AND METHODS: This was a retrospective nationwide survey from the GETAID Chirurgie. Any woman with CD undergoing surgery during pregnancy was eligible. RESULTS: A total of 15 cases were collected between 1992 and 2015. Most operations were performed due to penetrating or stricturing complications. Mean gestational age at delivery was 34 weeks, with a mean birth weight of 2507 g. Maternal post-operative complications occurred in two-thirds of cases. Maternal mortality rate was 6.7% and neonatal mortality rate 9.1%. CONCLUSIONS: This is the largest case series of surgery for CD during pregnancy. This operation may have significant morbidity and mortality for mother, fetus, and newborn. Indication needs to be tailored to maternal status, disease severity, and gestational age. Surgery should be managed by experienced gynecologists, physicians, and surgeons. Active CD may be associated with a greater risk to the fetus than the surgical procedure itself.

Abstract: International audience; Background - Few data exist to help select a second biologic agent in patients with refractory ulcerative colitis (UC). Aim - To compare the efficacy of infliximab (IFX) and vedolizumab (VDZ) in UC patients who failed a first subcutaneous anti-tumor necrosing factor (TNF) agent. Methods - Consecutive UC patients from 12 French centres starting IFX or VDZ after at least one injection of adalimumab or golimumab have been included in a retrospective study. Outcomes were clinical remission at week 14, survival without treatment discontinuation and survival without UC-related event. Results - Among the 225 patients included, clinical remission at week 14 was achieved in 40/154 (26%) patients treated with IFX and in 35/71 (49%) treated with VDZ (P = 0.001). After a propensity score matching analysis, this difference remained significant (odds ratio: 1.67; 95% confidence interval: 1.08-2.56; P = 0.02). With a median follow-up of 117 weeks, survival rates without treatment discontinuation at years 1 and 3 were 50% and 29% with IFX, and 80% and 55% with VDZ, respectively (P

Abstract: Background Endoscopic-post-operative-recurrence [ePOR] in Crohn’s disease [CD] after ileocecal resection [ICR] is a major concern. We aimed to evaluate the effectiveness of early prophylaxis with biologics and to compare anti-tumour necrosis factor [anti-TNF] therapy to vedolizumab [VDZ] and ustekinumab [UST] in a real-world setting. Methods A retrospective multicentre study of CD-adults after curative ICR on early prophylaxis was undertaken. ePOR was defined as a Rutgeerts score [RS] ≥ i2 or colonic-segmental-SES-CD ≥ 6. Multivariable logistic regression was used to evaluate risk factors, and inverse probability treatment weighting [IPTW] was applied to compare the effectiveness between agents. Results The study included 297 patients (53.9% males, age at diagnosis 24 years [19–32], age at ICR 34 years [26–43], 18.5% smokers, 27.6% biologic-naïve, 65.7% anti-TNF experienced, 28.6% two or more biologics and 17.2% previous surgery). Overall, 224, 39 and 34 patients received anti-TNF, VDZ or UST, respectively. Patients treated with VDZ and UST were more biologic experienced with higher rates of previous surgery. ePOR rates within 1 year were 41.8%. ePOR rates by treatment groups were: anti-TNF 40.2%, VDZ 33% and UST 61.8%. Risk factors for ePOR at 1 year were: past-infliximab (adjusted odds ratio [adj.OR] = 1.73 [95% confidence interval, CI: 1.01–2.97]), past-adalimumab [adj.OR = 2.32 [95% CI: 1.35-4.01] and surgical aspects. After IPTW, the risk of ePOR within 1 year of VDZ vs anti-TNF or UST vs anti-TNF was comparable (OR = 0.55 [95% CI: 0.25–1.19], OR = 1.86 [95% CI: 0.79–4.38]), respectively. Conclusion Prevention of ePOR within 1 year after surgery was successful in ~60% of patients. Patients treated with VDZ or UST consisted of a more refractory group. After controlling for confounders, no differences in ePOR risk were seen between anti-TNF prophylaxis and other groups.

Abstract: Although it is admitted that secondary infection can complicate viral diseases, the consequences of viral infection on cell susceptibility to other infections remain underexplored at the cellular level. We though to examine whether the sustained macroautophagy/autophagy associated with measles virus (MeV) infection could help cells oppose invasion by Salmonella Typhimurium, a bacterium sensitive to autophagic restriction. We report here the unexpected finding that Salmonella markedly replicated in MeV-infected cultures due to selective growth within multinucleated cells. Hyper-replicating Salmonella localized outside of LAMP1-positive compartments to an extent that equaled that of the predominantly cytosolic sifA mutant Salmonella. Bacteria were subjected to effective ubiquitination but failed to be targeted by LC3 despite an ongoing productive autophagy. Such a phenotype could not be further aggravated upon silencing of the selective autophagy regulator TBK1 or core autophagy factors ATG5 or ATG7. MeV infection also conditioned primary human epithelial cells for augmented Salmonella replication. The analysis of selective autophagy receptors able to target Salmonella revealed that a lowered expression level of SQSTM1/p62 and TAX1BP1/T6BP autophagy receptors prevented effective anti-Salmonella autophagy in MeV-induced syncytia. Conversely, as SQSTM1/p62 is promoting the cytosolic growth of Shigella flexneri, MeV infection led to reduced Shigella replication. The results indicate that the rarefaction of dedicated autophagy receptors associated with MeV infection differentially affects the outcome of bacterial coinfection depending on the nature of the functional relationship between bacteria and such receptors. Thus, virus-imposed reconfiguration of the autophagy machinery can be instrumental in determining the fate of bacterial coinfection.Abbreviations: ACTB/β-ACTIN: actin beta; ATG: autophagy related; BAFA1: bafilomycin A1; CFU: colony-forming units; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; FIP: fusion inhibitory peptide; GFP: green fluorescent protein; LAMP1: lysosomal associated membrane protein 1; LIR: MAP1LC3/LC3-interacting region; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MeV: measles virus; MOI: multiplicity of infection; OPTN: optineurin; PHH: primary human hepatocyte; SCV: Salmonella-containing vacuoles; SQSTM1/p62: sequestosome 1; S. flexneri: Shigella flexneri; S.

Abstract: Background and aims Inflammatory bowel diseases (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), and human immunodeficiency virus (HIV) both impact innate and adaptive immunity in the intestinal mucosa. As it is a rare situation, the intersection between HIV and IBD remains unclear, especially the impact of HIV infection on the course of IBD, and the drug safety profile is unknown. Methods We conducted a multicenter retrospective cohort study between January 2019 and August 2020. All adult patients with IBD and concomitant HIV infection were included. Each IBD patient with HIV was matched to two HIV-uninfected IBD patients. Results Overall, 195 patients with IBD were included, including 65 HIV-infected patients and 130 without HIV infection. Of the 65 infected patients, 22 (33.8%) required immunosuppressants and 31 (47.7%) biologics. In the HIV-infected group, the need for immunosuppressants (p = 0.034 for CD and p = 0.012 for UC) and biologics (p = 0.004 for CD and p = 0.008 for UC) was significantly lower. The disease course, using a severity composite criterion, was not significantly different between the two groups for CD (hazard ration (HR) = 1.3 [0.7; 2.4], p = 0.45) and UC (HR, 1.1 [0.5; 2.7], p = 0.767). The overall drug safety profile was statistically similar between the two groups. Conclusion Although HIV-infected patients receive less treatments, the course of their IBD did not differ than uninfected, suggesting that HIV infection might attenuate IBD. The drug safety profile is reassuring, allowing physician to treat these patients according to current recommendations.

Abstract: Background Owing to growing number of therapeutic options with similar efficacy and safety, we compared the acceptability of therapeutic maintenance regimens in inflammatory bowel disease (IBD). Methods From a nationwide study (24 public or private centers), IBD patients were consecutively included for 6 weeks. A dedicated questionnaire including acceptability numerical scales (ANS) ranging from 0 to 10 (highest acceptability) was administered to both patients and related physicians. Results Among 1850 included patients (65.9% with Crohn’s disease), the ANS were 8.68 ± 2.52 for oral route (first choice in 65.8%), 7.67 ± 2.94 for subcutaneous injections (first choice in 21.4%), and 6.79 ± 3.31 for intravenous infusions (first choice in 12.8%; P < .001 for each comparison). In biologic-naïve patients (n = 315), the most accepted maintenance regimens were oral intake once (ANS = 8.8 ± 2.2) or twice (ANS = 6.9 ± 3.4) daily and subcutaneous injections every 12 or 8 weeks (ANS = 7.9 ± 3.0 and ANS = 7.2 ± 3.2, respectively). Among 342 patients with prior exposure to subcutaneous biologics, the preferred regimens were subcutaneous injections (≥2 week-intervals; ANS between 9.1 ± 2.3 and 8.1 ± 2.7) and oral intake once daily (ANS = 7.7 ± 3.2); although it was subcutaneous injections every 12 or 8 weeks (ANS = 8.4 ± 3.0 and ANS = 8.1 ± 3.0, respectively) and oral intake once daily (ANS = 7.6 ± 3.1) in case of prior exposure to intravenous biologics (n = 1181). The impact of usual therapeutic escalation or de-escalation was mild (effect size Conclusions Although oral intake is overall preferred, acceptability is highly impacted by the rhythm of administration and prior medication exposures. However, SC treatment with long intervals between 2 injections (≥8 weeks) and oral intake once daily seems to be the most accepted modalities.

Abstract: Autophagy ensures the degradation of cytosolic substrates by the lysosomal pathway. Cargoes destined to be eliminated are confined within double-membrane vesicles called autophagosomes, prior to fusion with endolysosomal vacuoles. Autophagy receptors selectively interact with cargoes and route them to elongating autophagic membranes, a process referred to as selective autophagy. Besides contributing to cell homeostasis, selective autophagy constitutes an important cell-autonomous defense mechanism against viruses. We review observations related to selective autophagy receptor engagement during host cell responses to virus infection. We examine the distinct roles of autophagy receptors in antiviral autophagy, consider the strategies viruses have evolved to escape or oppose such restrictions, and delineate the contributions of selective autophagy to the tailoring of antiviral innate responses. Finally, we mention some open and emerging questions in the field.

Abstract: We used the postoperative recurrence model to better understand the role of adherent and invasiveFrom a prospective, multicentre cohort of operated patients with CD, AIEC identification was performed within the surgical specimen (M0) (N=181 patients) and the neoterminal ileum (n=119 patients/181) during colonoscopy performed 6 months after surgery (M6). Endoscopic postoperative recurrence was graded using Rutgeerts' index. The mucosa-associated microbiota was analysed by 16S sequencing at M0 and M6. Relative risks or ORs were adjusted on potential confounders.AIEC prevalence was twofold higher within the neoterminal ileum at M6 (30.3%) than within the surgical specimen (14.9%) (p0.001). AIEC within the neoterminal ileum at M6 was associated with higher rate of early ileal lesions (i1) (41.6% vs 17.1%; aRR 3.49 (95% CI 1.01 to 12.04), p=0.048) or ileal lesions (i2b+i3) (38.2% vs 17.1%; aRR 3.45 (95% CI 1.06 to 11.30), p=0.040) compared with no lesion (i0). AIEC within the surgical specimen was predictive of higher risk of i2b-endoscopic postoperative recurrence (POR) (aOR 2.54 (95% CI 1.01 to 6.44), p=0.049) and severe endoscopic POR (aOR 3.36 (95% CI 1.25 to 9.06), p=0.017). While only 5.0% (6/119) of the patients were AIEC-positive at both M0 and M6, 43.7% (52/119), patients with history of positive test for AIEC (M0 or M6) had higher risk of ileal endoscopic POR (aOR 2.32 (95% CI 1.01 to 5.39), p=0.048)), i2b-endoscopic postoperative recurrence (aOR 2.41 (95% CI 1.01 to 5.74); p=0.048) and severe endoscopic postoperative (aOR=3.84 (95% CI 1.32 to 11.18), p=0.013). AIEC colonisation was associated with a specific microbiota signature including increased abundance ofBased on the postoperative recurrence model, our data support the idea that AIEC are involved in the early steps of ileal CD.NCT03458195.

Abstract: Patients with inflammatory bowel disease have an increased risk of venous thromboembolism (VTE) and cardiovascular disease (CVD). The study aims to determine the prevalence of CVD and VTE risk factors in a large population of patients with ulcerative colitis (UC).We conducted a cross-sectional study in 33 French and Belgium referral centers. A questionnaire was developed to explore self-reported risk factors for VTE and CVD, based on the latest international guidelines, in consecutive patients with UC.A total of 1071 patients with UC were included. There were 539 women (50.3%), and the median age of patients was 44 years [32; 57]. The median disease duration was 10 years [6; 17]. In the cohort, 36.5% of patients reported no cardiovascular risk factor (CVRF) and 72% had ≤ 1 CVRF. Regarding cardiovascular risk markers (CVRM) 36.9% of patients reported no CVRM and 78% had ≤ 1 CVRM. Of the 1071 patients, 91.3% of patients reported no VTE strong risk factor and 96% had ≤ 1 VTE moderate risk factor.This is the first cohort specifically designed to assess both VTE and CVD risks in patients with UC. More than one third of patients with UC had no CVRF and around three quarters had ≤ 1 CVRF. In addition, more than nine out of ten patients had no VTE strong risk factor and ≤ 1 moderate risk factor. Physicians should be aware of these factors in their patients.

Abstract: Golimumab is a monoclonal anti-tumor necrosis factor alpha antibody, which is used in ulcerative colitis with an exposure-response relationship. The goal of this study was to compare results obtained with different immunoassays (golimumab and antigolimumab antibodies trough levels).This study was based on samples from 78 ulcerative colitis patients on golimumab treatment. Golimumab was quantified by either an anti-IgG detection antibody (Theradiag, Marne la Vallée, France) or an antibody directed against golimumab (Sanquin, Amsterdam, The Netherlands, KU Leuven, Leuven, Belgium, and Janssen RD, San Diego, CA). Bridging drug-sensitive enzyme-linked immunosorbent assays (Theradiag, Janssen RD, and KU Leuven), a bridging drug-tolerant enzyme-linked immunosorbent assay (Janssen RD), and a radioimmunoassay (Sanquin) were used to quantify antidrug antibody.Median serum golimumab levels were 4.5, 3.5, 4.9, and 2.4 mcg/mL with Theradiag, Sanquin, KU Leuven, and Janssen RD assay, respectively (P0.05). Correlation coefficients between assays ranged from 0.9 to 0.97. When using the KU Leuven and Janssen RD assays, 86% of samples were in the same quartile of distribution of values, and for Sanquin and Janssen RD assays, this overlap was 80%. The concordance observed for the other pairs was 83% (Sanquin/KU Leuven RD), 71% (Theradiag/KU Leuven), and 68% (Theradiag/Janssen RD and Theradiag/Sanquin). The specificity of assays for golimumab was demonstrated. Antidrug antibodies were detected in 28.2% of the samples with the Janssen RD drug-tolerant assay and in the same 2 patients by the 3 other assays.Performances of these immunoassays were similar in terms of quality, but differences in the quantitative results point to the importance of using the same assay consistently to monitor a patient's treatment.

Abstract: Confocal laser endomicroscopy (CLE) has been shown to predict relapse in inflammatory bowel disease, but its value in the detection of postoperative recurrence in Crohn's disease (CD) is unknown. The aims of this pilot study performed in patients with CD after ileocolonic resection were to compare the macroscopic appearance of the neoterminal ileum, according to the endoscopic Rutgeerts score, with the microscopic findings provided by CLE 6 to 12 months after surgery and to assess the predictive values of CLE-generated parameters for predicting further recurrence in patients with postoperative endoscopic remission.In 25 consecutive patients with CD within 6 to 12 months of surgery, the neoterminal ileum was examined by standard white-light endoscopy (Rutgeerts scale) followed by CLE (Watson grade). Only patients without endoscopic recurrence (Rutgeerts i0 and i1) were then followed endoscopically and clinically (median follow-up 38 months).At the time of the first postoperative colonoscopy, 18 patients (72%) were in endoscopic remission, and 7 (28%) experienced an endoscopic recurrence (Rutgeerts ≥i2). The Rutgeerts score was significantly correlated with the Watson score (ρ = 0 .73; P .0001). The Watson scores at baseline were significantly higher in patients with further endoscopic recurrence (median 2.0; interquartile range [IQR] 1.5-2.0) than in those with endoscopic remission (median 1.0; IQR 1.0-1.0; P = .032) and were significantly higher in patients with clinical relapse (medium 2.0, IQR 2.0-2.0) compared with those in clinical remission (median 1.0; IQR 1.0-1.0; P = .036).CLE could be useful in monitoring patients with CD after intestinal resection. Further studies with a larger population are necessary to confirm these preliminary results.

Abstract: Background Whether vedolizumab may be effective as a treatment for primary sclerosing cholangitis [PSC] in patients with inflammatory bowel disease [IBD] remains controversial. Methods We performed a retrospective observational study of consecutive patients with IBD and PSC, treated with vedolizumab for at least 30 weeks in 22 centres of GETAID from January 2015 to June 2016. The outcomes included a decrease in the serum alkaline phosphatase [ALP] concentration of at least 50% from baseline to Week 30 or 54, a change in any serum liver enzymes concentrations, and an assessment of the efficacy and safety of vedolizumab in IBD. Results Among 75 patients with active IBD and PSC treated with vedolizumab, 21 patients discontinued vedolizumab before Week 30 [due to lack of efficacy in 19 and malignancy in two patients]. In the remaining 54 patients, a decrease in the serum ALP concentration of at least 50% from baseline to Weeks 30 and 54 was observed in four [7%] and four [11%] patients, respectively. No significant change was observed in serum liver enzyme concentrations at week 30 or 54. After a median follow-up period of 19.4 [14.0–29.9] months, nine cases of digestive neoplasia [colorectal neoplasia in seven and cholangiocarcinoma in two] were reported. Conclusions In patients with IBD and PSC, vedolizumab did not improve serum liver enzyme concentrations at week 30 or 54. Nine cases of digestive cancer occurred during the follow-up period, confirming the need for a tight surveillance programme in this population.

Abstract: Introduction: The coronavirus disease 2019 (COVID-19) pandemic poses a challenge to healthcare. Staff and patients are at increased risk during an examination or intervention, so certain restrictions ought to be introduced. Hence, we aimed to measure the effect of the pandemic on endoscopy units in real-life settings. Methods: This was an observational, cross-sectional, questionnaire-based study, carried out between 7 April and 15 June 2020. Responds came from many countries, and the participation was voluntary. The survey contained 40 questions, which evaluated the effect of the COVID-19 pandemic on the endoscopy units and assessed the infection control. Results: A total of 312 questionnaires were filled, 120 from Hungary, and 192 internationally, and 54 questionnaires (17.3%) were sent from high-risk countries; 84.9% of the gastroenterologists declared that they read the European Society of Gastrointestinal Endoscopy (ESGE) statement, while only 32.1% participated in any advanced training at their workplace. Overall, 92.1% of gastroenterologists realized risk stratification, and 72.1% claimed to have enough protective equipment. In 52.6% of the endoscopy units, at least one endoscopist had to discontinue the work due to any risk factor, while 40.6% reported that the reduced staff did not affect the workflow. Gastroenterologists considered that the five most important examinations both in low and high-risk patients are the following: lower/upper gastrointestinal (GI) bleeding with hemodynamic instability, endoscopic retrograde cholangiopancreatography (ERCP) in obstructive jaundice, foreign body in the esophagus, ERCP in acute biliary pancreatitis, and iron deficiency anemia with hemodynamic instability, which correlates well with the ESGE recommendation. Significant correlation was found in the usage of the necessary protective equipment in high-risk patients depending on the countries ( p Conclusions: The survey found weak correlation in preliminary training depending on countries; nevertheless, in Hungary during the examined period, endoscopists considered the recommendations more strictly than in other countries. Although many physicians left the endoscopy lab, the workflow was not affected, probably due to the reduced number of examinations.

Abstract: Background and Aims Faecal calprotectin [FC] is a valid and non-invasive marker of mucosal inflammation. It is widely used both in clinical trials and in daily clinical practice for patients with inflammatory bowel diseases, but currently no accepted standardization for FC testing is available. Our primary aim here was to provide a clinician’s guide containing all the practical information on FC measurement in order to avoid any confounding factors, to minimize intra- and inter-individual variability in dosage, and to ensure a better and adequate interpretation of the results. Methods We conducted a detailed search of the scientific literature in the PubMed/MEDLINE, EMBASE and Cochrane databases up to January 2020 to find all relevant and available articles on pre-analytical and analytical phases of FC measurement. Results FC testing is a multi-step procedure consisting of a pre-analytical phase aimed to collect and process the stool sample and a subsequent analytical phase of FC measurement. Several factors can influence test results determining false positives or false negatives. Importantly, this faecal marker is mostly used for patient follow-up and as a predictor of treatment response. For this reason, any altered data may affect the physicians’ decisions, negatively impacting on patient management. Conclusions This review provides for the first time practical advice to minimize dosage variability, although further dedicated studies are needed to compare commercially available tests and identify the best tools for the most precise and accurate FC measurement.

Abstract: Background: Multiple studies have described the effectiveness of ustekinumab (UST) and vedolizumab (VDZ) in patients with Crohn’s disease (CD) failing anti- Tumor necrosis factors (TNFs), however, the effectiveness of VDZ or UST as a third-class biologic has not yet been described. Aims and Methods: In this retrospective multicenter cohort study, we aimed to investigate the effectiveness of VDZ and UST as a third-class biologic in patients with CD. Results: Two-hundred and four patients were included, 156/204 (76%) patients received VDZ as a second- and UST as a third-class therapy (group A), the remaining 48/204 (24%) patients received UST as a second- and VDZ as a third-class therapy (group B). At week 16–22, 87/156 (55.5%) patients and 27/48 (56.2%) in groups A and B, respectively, responded to treatment (p = 0.9), 41/156 (26.2%) and 15/48 (31.2%) were in clinical remission (p = 0.5). At week 52, 89/103 (86%) patients and 25/29 (86.2%) of the patients with available data had responded to third-class treatment in groups A and B, respectively (p = 0.9), 31/103 (30%) and 47/29 (24.1%) were in clinical remission (p = 0.5). Conclusion: Third-class biological therapy was effective in more than half of the patients with CD. No differences in effectiveness were detected between the use of VDZ and UST as a third-class agent.

Abstract: International audience; BACKGROUND/AIMS: In Crohn's disease (CD) few data are available on the usefulness of monitoring fecal calprotectin (FC) in the early postoperative setting. We assessed prospectively the accuracy of FC measured 3 months after surgery to predict the risk of endoscopic postoperative recurrence (POR) within 1 year after resection. METHODS: In 55 consecutive CD patients who had undergone ileocolonic resection samples were collected 3 months after surgery for measuring serum CRP and FC. Endoscopic POR was assessed by ileocolonoscopy within 6-12 months (median 7 months). Receiver operating characteristic (ROC) curves were generated to assess accuracy of the markers, to determine the best threshold and to calculate sensitivity, specificity, positive and negative predictive values. RESULTS: In contrast with median CRP levels, median FC concentrations measured 3 months after surgery were significantly higher in patients who later experienced endoscopic POR (Rutgeerts ≥ i2) compared with those who stayed in endoscopic remission within the following 6-12 months (205 μg/g IQR [106-721] vs. 103 μg/g IQR [60-219], p = 0.008). Area under the ROC curve for FC was 0.71. The best cutoff value of FC to identify patients in subsequent endoscopic remission 3 months after surgery was 65 μg/g (96% sensitivity, 31% specificity, 50% positive and 91% negative predictive values). In multivariate analysis, FC \textless 65 µg/g at 3 months was the only factor associated with subsequent endoscopic remission. CONCLUSION: FC measured 3 months after surgery below 65 μg/g is an accurate marker to identify CD patients who will later stay in endoscopic remission within 1 year after resection.
