Abstract
BACKGROUND AND AIMS Persons with inflammatory bowel disease (IBD) may be particularly vulnerable to COVID-19 either because of their underlying disease or its management. Guidance has been presented on the management of persons with IBD in the time of this pandemic by different groups. We aimed to determine how gastroenterologists around the world were approaching the management of IBD. METHODS Members of the World Gastroenterology Organization (WGO) IBD Task Force contacted colleagues in countries largely beyond North America and Europe, inviting them to review the WGO website for IBD and COVID-19 introduction, with links to guideline documents, and then to respond to 9 ancillary open-ended management questions. RESULTS Fifty-two gastroenterologists from 33 countries across 6 continents completed the survey (April 14 to May 16, 2020). They were all adhering for the most part to published guidelines on IBD management in the COVID-19 era. Some differences and reductions in services related to access, and some related to approach within their communities in terms of limiting virus spread. In particular, most gastroenterologists reduced in-person clinics (43 of 52), limited steroid use (47 of 51), limited elective endoscopy (45 of 52), and limited elective surgeries (48 of 51). If a patient was diagnosed with COVID-19, immunomodulatory therapy was mostly held. CONCLUSIONS In most countries, the COVID-19 pandemic significantly altered the approach to persons with IBD. The few exceptions were mostly based on low burden of COVID-19 in individual communities. Regardless of resources or health care systems, gastroenterologists around the world took a similar approach to the management of IBD.

Abstract
BACKGROUND AND AIM It is unclear whether vedolizumab therapy can be discontinued in patients with inflammatory bowel disease [IBD] after achieving steroid-free clinical remission. The aim was to assess the risk of relapse after vedolizumab therapy was discontinued. METHODS This was a retrospective observational study, collecting data from 21 tertiary centres affiliated with the GETAID from January 2017 to April 2019. Consecutive patients with IBD, who were in steroid-free clinical remission for at least 3 months and were treated with vedolizumab for at least 6 months, were included at the time of vedolizumab discontinuation. RESULTS A total of 95 patients [58 with Crohn's disease] discontinued vedolizumab after a median duration of therapy of 17.5 [10.6-25.4] months. After a median follow-up period of 11.2 [5.8-17.7] months, 61 [64%] patients experienced disease relapse. The probabilities of relapse-free survival were 83%, 59%, and 36% at 6, 12, and 18 months, respectively. According to the multivariate analysis, a C-reactive protein level less than 5 mg/L at vedolizumab discontinuation (hazard ratio [HR] = 0.56, 95% confidence interval [CI] [0.33-0.95], p = 0.03) and discontinuation due to patients' elective choice (HR = 0.41, 95% CI [0.21-0.80], p = 0.009) were significantly associated with a lower risk of relapse. Re-treatment with vedolizumab was noted in 24 patients and provided steroid-free clinical remission in 71% and 62.5% at Week 14 and after a median follow-up of 11.0 [5.4-13.3] months, respectively, without any infusion reactions. CONCLUSIONS In this retrospective study, two-thirds of patients with IBD treated with vedolizumab experienced relapse within the first year after vedolizumab discontinuation. Re-treatment with vedolizumab was effective in two-thirds of patients.

Abstract
BACKGROUND While Helicobacter pylori (H. pylori) is the major cause of gastric cancer, it has also been suggested to be involved in colorectal cancer development. However, prospective studies addressing H. pylori and colorectal cancer are sparse and inconclusive. We assessed the association of antibody responses to H. pylori proteins with colorectal cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. METHODS We applied H. pylori multiplex serology to measure antibody responses to 13 H. pylori proteins in prediagnostic serum samples from 485 colorectal cancer cases and 485 matched controls nested within the EPIC study. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariable conditional logistic regression to estimate the association of H. pylori overall and protein-specific seropositivity with odds of developing colorectal cancer. RESULTS Fifty-one percent of colorectal cancer cases were H. pylori seropositive compared with 44% of controls, resulting in an OR of 1.36 (95% CI, 1.00-1.85). Among the 13 individual H. pylori proteins, the association was driven mostly by seropositivity to Helicobacter cysteine-rich protein C (HcpC; OR: 1.66; 95% CI, 1.19-2.30) and Vacuolating cytotoxin A (VacA) (OR: 1.34; 95% CI, 0.99-1.82), the latter being nonstatistically significant only in the fully adjusted model. CONCLUSIONS In this prospective multicenter European study, antibody responses to H. pylori proteins, specifically HcpC and VacA, were associated with an increased risk of developing colorectal cancer. IMPACT Biological mechanisms for a potential causal role of H. pylori in colorectal carcinogenesis need to be elucidated, and subsequently whether H. pylori eradication may decrease colorectal cancer incidence.

Abstract
BACKGROUND The long-term outcome of patients with acute severe ulcerative colitis (ASUC) responding to intravenous steroids (IVS) has been poorly reported. AIMS To assess relapse-free survival in patients with ASUC responding to IVS. METHODS Between January 2006 and December 2017, 142 consecutive patients with ASUC (according to modified Truelove-and-Witts criteria) responding to IVS were included in this multicentre retrospective study. Relapse was defined by a partial Mayo Clinic score >4 and/or the need for another maintenance therapy. RESULTS Among the 142 included patients (100 naïve of immunomodulator and/or biological agent) hospitalised for ASUC, 59 (41.5%) were treated at discharge with 5-aminosalicylic acid, 60 (42%) with immunomodulators, 18 (13%) with anti-tumour necrosis factor (TNF) agents and 5 (3.5%) with vedolizumab. After a median follow-up of 4.8 (2.6-7.3) years, 90 (63.4%) had relapsed and 12 (8.5%) had required colectomy. The probabilities of relapse-free survival were 58%, 48% and 40% at 1, 2 and 5 years respectively. The multivariate analysis demonstrated that patients with <6 liquid stools per day at day 3 (hazard ratio 0.56, 95%CI [0.34-0.91]), a partial Mayo Clinic score <2 at day 5 (0.41 [0.21-0.80]) and anti-TNF maintenance therapy (0.37 [0.16-0.87]) were less likely to relapse. The probabilities of colectomy-free survival were 96%, 95% and 91% at 1, 2 and 5 years respectively. CONCLUSION Despite a high relapse rate, patients with ASUC responding to IVS had a low rate of colectomy after 5 years of follow-up. Early response to IVS and maintenance therapy with biological agents were associated with a lower rate of relapse.

Abstract
Background:Articular manifestations are the most frequent extra-digestive manifestations of Inflammatory Bowel Disease (IBD). Anti-TNF have proved to be as effective on articular symptoms as on IBD’s ones, but have been suspected to induce paradoxical articular manifestations.Objectives:The aims of this study were to describe the frequency, the type and the management of all articular manifestations occurring in patients treated with anti-TNF for IBD and to look for factors associated with their occurrence.Methods:In this retrospective monocentric study, we included all patients who received an anti-TNF for an IBD in our tertiary hospital referent for inflammatory rheumatic and bowel diseases. We searched for all incident articular manifestations occurring during treatment with anti-TNF, including new or recurrent articular manifestations. Characteristics of patients with paradoxical articular manifestations (defined as inflammatory articular symptoms occurring while IBD was in remission, without immunization against anti-TNF) were compared to that of patients without articular manifestations to identify factors associated with their occurrence.Results:Through a systematic search of all IBD patients seen in our tertiary hospital between February 2013 and May 2017, we identified 442 patients (36.2±15 years, 50.5% men) who had ever received an anti-TNF for IBD: Crohn’s disease (n=277), ulcerative colitis (154) and undetermined colitis (n=11). 74 (16.7%) had already a history of inflammatory articular manifestations including 37 patients with a diagnosis of spondyloarthritis (SpA) made before anti-TNF’s beginning.Among them, 115 (26%) patients developed a new articular manifestation after a mean of 20 (±22) months of treatment: mechanical in 56 (12.6%) and inflammatory in 59 (13.3%). Within patients with new inflammatory articular manifestations: 39% were paradoxical, 27% were concomitant of an IBD flare, 27% were associated to an immunization against anti-TNF, 3% were induced lupus, 2% were chondrocalcinosis and 2% were polymyalgia rheumatic. Articular manifestations associated to an immunization were linked to a loss of efficiency of the treatment for 62%, with (42%) or without (20%) associated digestive symptoms and 38% were due to delayed hypersensitivity reaction. Among paradoxical articular manifestations, 83% were new articular symptoms, including 35% of SpA de novo, and 17% were recurrence of known articular manifestations. The only predictive factor of paradoxical articular manifestation was a previous diagnosis of SpA (21.7% vs 6.8%; p=0.02). Paradoxical manifestations improved in 17 patients despite continuation of anti-TNF, methotrexate was added in 2 and anti-TNF was discontinued in only 4 patients.Conclusion:Inflammatory articular manifestations occurred in about 13% of patients treated with anti-TNF for IBD. More than a quarter were linked to an immunization against anti-TNF, which has to be searched in this situation. Less than half of them (39%) were paradoxical. In most of cases, they were transitory and did not require anti-TNF’s discontinuation. The only predictive factor of paradoxical articular manifestations was having a history of SpA.References:[1]Thiebault H, et al.

Abstract
BACKGROUND Interstitial lung [ILD] disease and granulomatous lung disease [GLD] are rare respiratory disorders that have been associated with inflammatory bowel disease [IBD]. Clinical presentation is polymorphic and aetiology is unclear. METHODS This was an ECCO-CONFER project. Cases of concomitant ILD or GLD and IBD, or drug-induced ILD/GLD, were collected. The criteria for diagnosing ILD and GLD were based on definitions from the American Thoracic Society and the European Respiratory Society and on the discretion of reporting clinician. RESULTS We identified 31 patients with ILD. The majority had ulcerative colitis [UC] [n = 22]. Drug-related ILD was found in 64% of these patients, 25 patients [80.6%] required hospitalisation, and one required non-invasive ventilation. The causative drug was stopped in all drug-related ILD, and 87% of patients received systemic steroids. At follow-up, 16% of patients had no respiratory symptoms, 16% had partial improvement, 55% had ongoing symptoms, and there were no data in 13%. One patient was referred for lung transplantation, and one death from lung fibrosis was reported. We also identified 22 GLD patients: most had Crohn's disease [CD] [n = 17]. Drug-related GLD was found in 36% of patients and 10 patients [45.4%] required hospitalisation. The causative drug was stopped in all drug-related GLD, and 81% of patients received systemic steroids. Remission of both conditions was achieved in almost all patients. CONCLUSIONS ILD and GLD, although rare, can cause significant morbidity. In our series, over half of cases were drug-related and therefore focused pharmacovigilance is needed to identify and manage these cases.

Abstract
Immune checkpoint inhibitors (ICIs) have improved the treatment of several cancers. These drugs increase T-cell activity and the antitumor immune response but also have immune-related adverse effects that can affect the gastrointestinal (GI) tract. These adverse effects have been observed in 7% to 30% of patients treated with ICIs. As the number of diseases treated with ICIs increases, gastroenterologists will see more patients with ICI-induced GI adverse events. We performed a systematic review of the incidence, risk factors, clinical manifestations, and management of the adverse effects of ICIs on the GI tract. Treatment with anti-cytotoxic T-lymphocyte-associated antigen-4 often causes severe enterocolitis, whereas treatment with inhibitors of programmed cell death 1 have less frequent and more diverse adverse effects. Management of patients with GI adverse effects of ICIs should involve first ruling out other disorders, followed by assessment of severity, treatment with corticosteroids, and rapid introduction of infliximab therapy for nonresponders.

Abstract
BACKGROUND There is no head-to-head trial comparing ustekinumab and vedolizumab in patients with Crohn's disease (CD) refractory to anti-tumour necrosis factor (anti-TNF). AIM To compare the effectiveness and safety of ustekinumab and vedolizumab in patients with CD refractory to anti-TNF in a multicentre retrospective observational cohort. METHODS All consecutive patients with CD refractory or intolerant to anti-TNF who initiated either vedolizumab or ustekinumab were included between May 2014 and August 2018. Clinical remission, steroid-free clinical remission (SFCR) and treatment persistence were assessed at week 48 with intention-to-treat analysis and propensity scores weighted comparison. RESULTS A total of 239 patients were included, 107 received ustekinumab and 132 received vedolizumab. At week 48, ustekinumab was associated with a higher clinical remission rate (54.4% vs 38.3%; odds ratios, OR = 1.92, 95% CI [1.09-3.39]) and treatment persistence (71.5% vs 49.7%; OR = 2.54, 95% CI [1.40-4.62]) than vedolizumab. The rate of SFCR did not differ significantly between ustekinumab and vedolizumab (44.7% vs 34.0%; OR = 1.57, 95% CI [0.88-2.79]). Subgroup analyses showed that ustekinumab was associated with a higher clinical remission rates at week 48 in patients with ileal location (OR = 3.49, 95% CI [1.33-9.17) and penetrating behaviour (OR = 6.58, 95% CI [1.91-22.68]). Regardless of the treatment group, combination therapy at initiation was associated with a higher clinical remission rate at week 48 (OR = 1.93, 95% CI [1.09-3.43]). CONCLUSION This study suggests that ustekinumab is associated with a higher rate of clinical remission and treatment persistence than vedolizumab after 48 weeks of follow-up, in patients with CD refractory or intolerant to anti-TNF. The rate of SFCR was not significantly different.

Abstract
Gut microbiota composition influences the clinical benefit of immune checkpoints in patients with advanced cancer but mechanisms underlying this relationship remain unclear. Molecular mechanism whereby gut microbiota influences immune responses is mainly assigned to gut microbial metabolites. Short-chain fatty acids (SCFA) are produced in large amounts in the colon through bacterial fermentation of dietary fiber. We evaluate in mice and in patients treated with anti-CTLA-4 blocking mAbs whether SCFA levels is related to clinical outcome. High blood butyrate and propionate levels are associated with resistance to CTLA-4 blockade and higher proportion of Treg cells. In mice, butyrate restrains anti-CTLA-4-induced up-regulation of CD80/CD86 on dendritic cells and ICOS on T cells, accumulation of tumor-specific T cells and memory T cells. In patients, high blood butyrate levels moderate ipilimumab-induced accumulation of memory and ICOS + CD4 + T cells and IL-2 impregnation. Altogether, these results suggest that SCFA limits anti-CTLA-4 activity. The gut microbiota has been reported to regulate the efficacy of cancer therapy. Here, the authors show that short-chain fatty acids, which are generated through bacterial fermentation, increases immune tolerance leading to resistance to anti-CTLA-4 immunotherapy in mice and patients with metastatic melanoma.

Abstract
Abstract
Objective
Vedolizumab (VDZ) has been incriminated in the occurrence of articular manifestations in patients with inflammatory bowel diseases (IBDs). The aim of this study was to describe musculoskeletal manifestations occurring in IBD patients treated by VDZ and to identify risk factors.
Methods
In this retrospective monocentric study, we included all consecutive patients treated by VDZ for IBD in our hospital. Incident musculoskeletal manifestations occurring during VDZ treatment were analysed and characteristics of patients with and without articular inflammatory manifestations were compared.
Results
Between 2013 and 2017, 112 patients were treated with VDZ for IBD: ulcerative colitis (n = 59), Crohn’s disease (n = 49) and undetermined colitis (n = 4). Four patients (3.6%) had a history of SpA, whereas 13 (11.6%) had a history of peripheral arthralgia. Some 102 (91.1%) patients had previously received anti-TNF. After a mean (S.d.) follow-up of 11.4 (8.6) months, 32 (28.6%) patients presented 35 musculoskeletal manifestations, of which 18 were mechanical and 17 inflammatory. Among the latter, 11 had axial or peripheral SpA, 5 had early reversible arthralgia and 1 had chondrocalcinosis (n = 1). Among the 11 SpA patients, only 3 (2.6%) had inactive IBD and may be considered as paradoxical SpA. The only factor associated with occurrence of inflammatory manifestations was history of inflammatory articular manifestation [7/16 (43.8%) vs 10/80 (12.5%), P = 0.007].
Conclusion
Musculoskeletal manifestations occurred in almost 30% of IBD patients treated with VDZ, but only half of them were inflammatory. Since most of the patients previously received anti-TNF, occurrence of inflammatory articular manifestations might rather be linked to anti-TNF discontinuation than to VDZ itself.

Abstract
BACKGROUND A clinical decision support tool (CDST) has been validated for predicting treatment effectiveness of vedolizumab (VDZ) in Crohn's disease. AIM To assess the utility of this CDST for predicting exposure-efficacy and disease outcomes. METHODS Using data from three independent datasets (GEMINI, GETAID and VICTORY), we assessed clinical remission rates and measured VDZ exposure, rapidity of onset of action, response to dose optimisation and progression to surgery by CDST-defined response groups (low, intermediate and high). RESULTS A linear relationship existed between CDST-defined groups, measured VDZ exposure, rapidity of onset of action and efficacy in GEMINI through week 52 (P < 0.001 at all time points across three CDST-defined groups). In GETAID, CDST predicted differences in clinical remission at week 14 (AUC = 0.68) and rapidity of onset of action (P = 0.04) between probability groups. The high-probability patients did not benefit from shortening of infusion intervals, and differences in onset of action between the high-intermediate and low-probability groups within GETAID were no longer significant when including low-probability patients who received a week 10 infusion. CDST predicted a twofold increase in surgery risk over 12 months of VDZ therapy among low- to intermediate-probability vs high-probability patients (adjusted HR 2.06, 95% CI 1.33-3.21). CONCLUSIONS We further extended the clinical utility of a previously validated VDZ CDST, which accurately predicts at baseline exposure-efficacy relationships and rapidity of onset of action and could be used to help identify patients who would most benefit from interval shortening and those most likely to require surgery while on active therapy.

Abstract
BACKGROUND Phase III trials demonstrated effectiveness of tofacitinib, an oral Janus kinase inhibitor, to induce and maintain remission in patients with moderate-to-severe active ulcerative colitis (UC). AIMS We report the real-world effectiveness and safety of tofacitinib in patients with UC in France. METHODS From February 2017 to December 2018, we performed a national French cohort study, which included all consecutive patients with an active UC refractory to anti-TNF and vedolizumab, who received tofacitinib. Outcomes were survival without colectomy, survival without tofacitinib discontinuation and steroid-free clinical remission at weeks 14, 24 and 48. RESULTS Thirty-eight patients were included, with a median follow-up of 41.5 (18.5-56.8) weeks. Survival without colectomy was 77% [95% confidence interval (95%CI): 59.3-87.9] at week 24 and 70% (95%CI: 50.9-82.8) at week 48. Survival without treatment discontinuation was 70% (95%CI: 52.6-82.3) at week 24. Steroid-free clinical remission was observed in 13 (34%) patients at week 48. Adverse events occurred in 14 (37%) patients, including 6 severe adverse events and three herpes zoster infections. CONCLUSION In a highly refractory UC population, one third of patients treated with tofacitinib achieved steroid-free clinical remission at week 14 and 70% of patients avoided colectomy at one year, with an acceptable safety profile. These data confirm tofacitinib effectiveness in UC, especially after multiple biologic failures.

Abstract
Obesity has been associated with upper gastrointestinal cancers; however, there are limited prospective data on associations by subtype/subsite. Obesity can impact hormonal factors, which have been hypothesized to play a role in these cancers. We investigated anthropometric and reproductive factors in relation to esophageal and gastric cancer by subtype and subsite for 476,160 participants from the European Prospective Investigation into Cancer and Nutrition cohort. Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox models. During a mean follow-up of 14 years, 220 esophageal adenocarcinomas (EA), 195 esophageal squamous cell carcinomas, 243 gastric cardia (GC) and 373 gastric noncardia (GNC) cancers were diagnosed. Body mass index (BMI) was associated with EA in men (BMI ≥30 vs. 18.5-25 kg/m2 : HR = 1.94, 95% CI: 1.25-3.03) and women (HR = 2.66, 95% CI: 1.15-6.19); however, adjustment for waist-to-hip ratio (WHR) attenuated these associations. After mutual adjustment for BMI and HC, respectively, WHR and waist circumference (WC) were associated with EA in men (HR = 3.47, 95% CI: 1.99-6.06 for WHR >0.96 vs. <0.91; HR = 2.67, 95% CI: 1.52-4.72 for WC >98 vs. <90 cm) and women (HR = 4.40, 95% CI: 1.35-14.33 for WHR >0.82 vs. <0.76; HR = 5.67, 95% CI: 1.76-18.26 for WC >84 vs. <74 cm). WHR was also positively associated with GC in women, and WC was positively associated with GC in men. Inverse associations were observed between parity and EA (HR = 0.38, 95% CI: 0.14-0.99; >2 vs. 0) and age at first pregnancy and GNC (HR = 0.54, 95% CI: 0.32-0.91; >26 vs. <22 years); whereas bilateral ovariectomy was positively associated with GNC (HR = 1.87, 95% CI: 1.04-3.36). These findings support a role for hormonal pathways in upper gastrointestinal cancers.

Abstract
BACKGROUND Acute severe ulcerative colitis (ASUC) is a life-threatening condition. Mortality in ASUC decreased in published series but there is uncertainty as to whether this also applies to the real-life setting. AIM To perform a systematic review and meta-analysis of mortality in ASUC in studies from referral centres and in population-based studies, separately and combined. A second aim was to identify risk factors of mortality in ASUC. METHODS We searched pubmed and embase from 1998 to 2016, to identify studies that reported 3-month or 12-month mortalities of acute UC in adult patients treated in referral centres, and in population-based studies. RESULTS Six population-based studies with 741 743 patients and 47 referral centre-based studies with 2556 patients were included. The pooled 3-month and 12-month mortalities were respectively 0.84% and 1.01%. Advanced age was significantly associated with both 3 month and 12 month mortalities (OR = 1.15 per year, 95% CI: 1.10-1.20 and OR = 1.19 per year, 95% CI: 1.15-1.23 respectively). The pooled 3-month and 12-month mortalities were 0.78% and 0.85% in studies with median age of less than 50 and 2.81% and 4.17% in studies with median age of 50 or more, respectively. After adjustment for age, 3-month and 12-month mortalities did not differ between population-based and referral centre-based studies. CONCLUSIONS Mortality in acute severe ulcerative colitis is approximately 1%; it is higher in older patients. Efforts should be made to improve the care of elderly patients with severe UC.

Abstract
Abstract
Background
More than one million colonoscopies are performed every year in France. They are associated with risks of mechanical and systemic serious adverse events (SAEs) which can be associated with patient, procedure, endoscopist, and facility characteristics. We tried to identify the factors associated with colonic perforation, gastrointestinal bleeding, splenic injury, shock, myocardial infarction, stroke, pulmonary embolism, acute renal failure, and urolithiasis after colonoscopy.
Methods
We analysed data from the French national claims databases (SNDS). A total of 4,088,799 patients, 30 years or older, undergoing a first screening or diagnostic colonoscopy between 2010 and 2015 were identified. SAE rates were estimated, and risk factors associated with SAEs were identified using multilevel logistic regression models, adjusted for patient, colonoscopy, endoscopist, and facility characteristics.
Results
Increasing age was associated with an increasing incidence of mechanical and systemic SAEs. Cancer and cardiovascular comorbidities were associated with mechanical SAEs, and a higher number of pre-existing conditions was associated with shock and acute renal failure. Polypectomy, especially of polyps larger than 1 cm, was associated with an increased risk of perforation (OR = 4.1; 95% CI, 3.4-5.0) and bleeding (OR = 13.3; 95% CI, 11.7-15.1). Mechanical SAEs were associated with the endoscopist’s experience, while systemic SAEs were more frequent in public hospitals than in private clinics.
Conclusions
SAEs related to colonoscopy were more frequent in older patients and in those with comorbidities. Mechanical SAEs were more frequent when colonoscopy was performed by less experienced endoscopists. Systemic SAEs were more frequent in public hospitals, reflecting patient selection processes. The risk of both mechanical and systemic SAEs should be taken into account when deciding to perform colonoscopy, particularly in older patients with multiple pre-existing conditions.
Key messages
Systemic SAEs are not uncommon after colonoscopy and, together with intestinal SAEs, should be considered when considering the need for colonoscopy. Patients at risk of SAEs should be identified and colonoscopy should be performed by experienced endoscopists in these patients. Less invasive alternatives should also be considered in these patients.

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
Gallstones, a common gastrointestinal condition, can lead to several digestive complications and can result in inflammation. Risk factors for gallstones include obesity, diabetes, smoking and physical inactivity, all of which are known risk factors for colorectal cancer (CRC), as is inflammation. However, it is unclear whether gallstones are a risk factor for CRC. We examined the association between history of gallstones and CRC in the European Prospective Investigation into Cancer and Nutrition (EPIC) study, a prospective cohort of over half a million participants from ten European countries. History of gallstones was assessed at baseline using a self-reported questionnaire. The analytic cohort included 334,986 participants; a history of gallstones was reported by 3,917 men and 19,836 women, and incident CRC was diagnosed among 1,832 men and 2,178 women (mean follow-up: 13.6 years). Hazard ratios (HR) and 95% confidence intervals (CI) for the association between gallstones and CRC were estimated using Cox proportional hazards regression models, stratified by sex, study centre and age at recruitment. The models were adjusted for body mass index, diabetes, alcohol intake and physical activity. A positive, marginally significant association was detected between gallstones and CRC among women in multivariable analyses (HR = 1.14, 95%CI 0.99-1.31, p = 0.077). The relationship between gallstones and CRC among men was inverse but not significant (HR = 0.81, 95%CI 0.63-1.04, p = 0.10). Additional adjustment for details of reproductive history or waist circumference yielded minimal changes to the observed associations. Further research is required to confirm the nature of the association between gallstones and CRC by sex.

Abstract
BACKGROUND There is a lack of prospective data on the potential association of Fusobacterium nucleatum (F. nucleatum) and colorectal cancer risk. In this study, we assessed whether antibody responses to F. nucleatum are associated with colorectal cancer risk in prediagnostic serum samples in the European Prospective Investigation into Nutrition and Cancer (EPIC) cohort. METHODS We applied a multiplex serology assay to simultaneously measure antibody responses to 11 F. nucleatum antigens in prediagnostic serum samples from 485 colorectal cancer cases and 485 matched controls. Conditional logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CI). RESULTS We observed neither a statistically significant colorectal cancer risk association for antibodies to individual F. nucleatum proteins nor for combined positivity to any of the 11 proteins (OR, 0.81; 95% CI, 0.62-1.06). CONCLUSIONS Antibody responses to F. nucleatum proteins in prediagnostic serum samples from a subset of colorectal cancer cases and matched controls within the EPIC study were not associated with colorectal cancer risk. IMPACT Our findings in prospectively ascertained serum samples contradict the existing literature on the association of F. nucleatum with colorectal cancer risk. Future prospective studies, specifically detecting F. nucleatum in stool or tissue biopsies, are needed to complement our findings.

Abstract
Higher circulating 25-hydroxyvitamin D levels (25(OH)D) have been found to be associated with lower risk for colorectal cancer (CRC) in prospective studies. Whether this association is modified by genetic variation in genes related to vitamin D metabolism and action has not been well studied in humans. We investigated 1307 functional and tagging single-nucleotide polymorphisms (SNPs; individually, and by gene/pathway) in 86 vitamin D-related genes in 1420 incident CRC cases matched to controls from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. We also evaluated the association between these SNPs and circulating 25(OH)D in a subset of controls. We confirmed previously reported CRC risk associations between SNPs in the VDR, GC, and CYP27B1 genes. We also identified additional associations with 25(OH)D, as well as CRC risk, and several potentially novel SNPs in genes related to vitamin D transport and action (LRP2, CUBN, NCOA7, and HDAC9). However, none of these SNPs were statistically significant after Benjamini-Hochberg (BH) multiple testing correction. When assessed by a priori defined functional pathways, tumor growth factor β (TGFβ) signaling was associated with CRC risk (P ≤ 0.001), with most statistically significant genes being SMAD7 (PBH = 0.008) and SMAD3 (PBH = 0.008), and 18 SNPs in the vitamin D receptor (VDR) binding sites (P = 0.036). The 25(OH)D-gene pathway analysis suggested that genetic variants in the genes related to VDR complex formation and transcriptional activity are associated with CRC depending on 25(OH)D levels (interaction P = 0.041). Additional studies in large populations and consortia, especially with measured circulating 25(OH)D, are needed to confirm our findings.

Abstract
BACKGROUND CT-P13, a biosimilar of the reference product infliximab, has been approved for the treatment of ulcerative colitis on the basis of the results of trials conducted in patients with spondyloarthritis and rheumatoid arthritis. AIM To compare the effectiveness and safety of CT-P13 and the reference product in infliximab-naive patients with ulcerative colitis METHODS: A comparative real-life equivalence cohort study was conducted using the French nationwide health administrative database. Infliximab-naive patients with ulcerative colitis over 15 years of age who started infliximab with no other indications for infliximab were included. The primary outcome was a composite endpoint (death, ulcerative colitis-related surgery, all-cause hospitalisation and reimbursement for other biologics). Equivalence was defined as a 95% CI of the hazard ratio (HR) of CT-P13 vs the reference product, in a multivariable marginal Cox model situated within prespecified margins of (0.80-1.25). RESULTS A total of 3112 patients were included between 1 January 2015 and 30 June 2017: 1434 received the reference product, 1678 received CT-P13. Overall, 710 patients in the reference product group and 743 patients in the CT-P13 group met the composite endpoint. In multivariable analysis of the primary outcome, CT-P13 was equivalent to the reference product (HR 1.04; 95% CI: 0.94-1.15). The number of serious infections was lower in the CT-P13 group (HR 0.65; 95% CI: 0.48-0.88). There was no difference in the incidence of solid or haematologic malignancy (HR 0.81; 95% CI: 0.41-1.60). CONCLUSIONS The effectiveness of CT-P13 is equivalent and the risk of serious infections could be lower than that of the reference product for infliximab-naive patients with ulcerative colitis.
