ABSTRACT
BACKGROUND: Anti-TNF are usually maintained during pregnancy in patients with inflammatory bowel disease (IBD) but safety is still a concern for them. AIMS: To provide data on management of anti-TNF agents during pregnancy, safety of live vaccines (BCG-MMR-rotavirus) and breastfeeding in newborns and dedicated information delivered to IBD women. METHODS: We performed an observational study in 25 centers from 2016 to 2018. We administered questionnaires to women with IBD receiving anti-TNF during pregnancy with newborn follow-up ≥ one year. RESULTS: Of 153 patients, 52 % maintained anti-TNF during the third trimester. Anti-TNF was shortly resumed in 79 % (58/73) after delivery. The rate of breastfeeding was 44 % (68/153) without any complication; 38 % of the mothers denied to breastfeed based on physician's advice. 26 % (34/129) of the newborns received live vaccines before 6 months-old (BCG:30 %; MMR:63 %; Rotavirus:8 %) and only 3 complications occurred (local BCGitis=1, fever=2). Information concerning anti-TNF during pregnancy/post-partum was delivered to 92 % of the patients, mainly by a gastroenterologist (97 %) who discussed with the obstetrician or the paediatrician in only 48 % and 25 %. CONCLUSION: In IBD patients, maintaining anti-TNF during pregnancy and breastfeeding is safe. Accidental live vaccines before 6 months did not lead to significant adverse events. The communication about these questions remains to improve.
ABSTRACT
BACKGROUND: Infliximab and vedolizumab are widely used to treat Crohn's disease (CD) and ulcerative colitis (UC). AIMS: This systematic review and network meta-analysis evaluated comparative efficacy of various regimens for intravenous or subcutaneous infliximab and vedolizumab during maintenance treatment in CD and UC. METHODS: Parallel-group randomized controlled trials (RCTs) were identified by a systematic literature review (CRD42022383401) and included if they evaluated therapeutics of interest for maintenance treatment of adults with moderate-to-severe luminal CD or UC and assessed clinical remission between Weeks 30 and 60. Clinical remission rates in CD or UC and mucosal healing rates in UC were analyzed in a Bayesian network meta-analysis model. Endoscopic outcomes in CD were synthesized by proportional meta-analysis. RESULTS: Overall, 13 RCTs were included in the analyses. All vedolizumab studies randomized induction responders to maintenance treatment; infliximab studies used a treat-through design. Subcutaneous infliximab 120 mg every 2 weeks had the highest odds ratio (OR) [95% credible interval] versus placebo for clinical remission during the maintenance phase (CD: 5.90 [1.90-18.2]; UC: 5.45 [1.94-15.3]), with surface under the cumulative ranking curve (SUCRA) values of 0.91 and 0.82, respectively. For mucosal healing in UC, subcutaneous infliximab 120 mg every 2 weeks showed the highest OR (4.90 [1.63-14.1]), with SUCRA value of 0.73, followed by intravenous vedolizumab 300 mg every 4 weeks (SUCRA value, 0.70). Endoscopic outcomes in CD were better with subcutaneous infliximab 120 mg every 2 weeks than intravenous infliximab 5 mg/kg every 8 weeks. CONCLUSIONS: Subcutaneous infliximab showed a favorable efficacy profile for achieving clinical remission and endoscopic outcomes during maintenance treatment in CD or UC.

INTRODUCTION: Knowledge about the cancer risk when initiating a biologic in inflammatory bowel disease [IBD] patients with prior malignancy remains scarce, especially for vedolizumab. Our aim was to evaluate the rate of incident cancer in a cohort of IBD patients with prior non-digestive malignancy, according to the subsequent treatment given. METHODS: A multicentre retrospective study included consecutive IBD patients with prior non-digestive malignancy. Inclusion date corresponded to the diagnosis of index malignancy. Patients were categorized into different cohorts according to the first treatment [none, conventional immunosuppressant, anti-TNF, or vedolizumab] to which they were exposed after inclusion and before incident cancer [recurrent or new cancer]. RESULTS: Among the 538 patients {58% female; mean (standard deviation [SD]) age inclusion: 52 [15] years} analyzed, the most frequent malignancy was breast cancer [25%]. The first immunomodulator given after inclusion was a conventional immunosuppressant in 27% of patients, anti-TNF in 21%, or vedolizumab in 9%. With a median (interquartile range [IQR]) follow-up duration of 55 [23-100] months, 100 incident cancers were observed. Crude cancer incidence rates per 1000 person-years were 47.0 for patients receiving no immunomodulator, 36.6 in the anti-TNF cohort, and 33.6 in the vedolizumab cohort [p = 0.23]. Incident-cancer free survival rates were not different between patients receiving anti-TNF and those receiving vedolizumab [p = 0.56]. After adjustment, incidence rates were not different between patients receiving no immunomodulator, anti-TNF, or vedolizumab. CONCLUSIONS: In this large multicentre cohort study, there was no difference of cancer incidence in those IBD patients with prior non-digestive malignancy, treated with vedolizumab or anti-TNF.

BACKGROUND AND AIMS: Optimal management of patients with inflammatory bowel disease [IBD] after anti-tumour necrosis factor [TNF] discontinuation due to severe induced skin lesions is unclear. Our study aimed to describe dermatological and IBD evolution after anti-TNF discontinuation for this side effect. METHODS: We conducted a multicentre retrospective study including consecutive IBD patients who discontinued anti-TNF due to severe induced skin lesions. Our objectives were to determine factors associated with dermatological remission [complete disappearance of skin lesions] and with IBD relapse in patients with inactive disease at inclusion, notably the impact of an early switch to another biological agent within 3 months of anti-TNF discontinuation. RESULTS: Among the 181 patients [134 women, 160 Crohn's disease] included in the 13 participating centres, dermatological remission occurred in 110 [62%] patients with a median [interquartile range, IQR] interval of 8.0 [6.8-11.0] months. Scalp location was independently associated with less remission of skin lesions (hazard ratio [HR] = 0.64 [95% CI 0.43-0.94], p = 0.02) while early switch was independently associated with a higher probability of remission of skin lesions (HR = 1.64 [95% CI 1.1-2.5], p = 0.02). Among the 148 patients with inactive IBD at inclusion, disease relapse occurred in 75 [51%] patients with a median [IQR] interval of 26.0 [23.0-39.1] months. Survival rates without IBD relapse at 1 year were 85.8% [95% CI 77.5-94.9] in the early switch group and 59.3% [95% CI 48.9-71.9] in the other group [p < 0.01]. CONCLUSIONS: Early switch to a new biological is associated with a higher probability of healing of anti-TNF-induced skin lesions and significantly reduces the risk of IBD relapse.

In inflammatory bowel disease [IBD], mucosal healing is a major therapeutic target and a reliable predictor of clinical course. However, endoscopic mucosal healing is not synonymous with histological healing, and the additional benefits of including histological remission as a target are unclear. In Crohn´s disease [CD], there are few studies highlighting the value of histological remission as a therapeutic target. Histological activity can persist in CD patients who are in endoscopic remission, and the absence of histological activity may be associated with lower relapse rates. Therefore, standardisation of procedures to evaluate CD histological activity is desirable. Topics that would benefit from standardisation and harmonisation include biopsy procedures, biopsy processing techniques, the content of histological scores, and the definitions of histological remission, histological response, and histological activity. In line with these needs, the European Crohn's and Colitis Organisation [ECCO] assembled a consensus group with the objective of developing position statements on CD histology based on published evidence and expert consensus. There was agreement that definitions of histological remission should include absence of erosion, ulceration, and mucosal neutrophils; that the absence of neutrophilic inflammation is an appropriate histological target in CD; that CD histological scores, such as the Global Histological Disease Activity Score, lack formal validation; and that histological scoring systems for ulcerative colitis, including the Geboes Score, Robarts Histopathology Index, and Nancy Histological Index, can be used for scoring intestinal biopsies in CD patients.

BACKGROUND: Better patient knowledge on inflammatory bowel disease [IBD] could improve outcome and quality of life. The aim of this study was to assess if an education programme improves IBD patients' skills as regards their disease. METHODS: The GETAID group conducted a prospective multicentre randomised controlled study. IBD patients were included at diagnosis, or after a significant event in the disease course. Patients were randomised between 'educated' or control groups for 6 months. Education was performed by trained health care professionals. A psycho-pedagogic score [ECIPE] was evaluated by a 'blinded' physician at baseline and after 6 and 12 months [M6 and M12]. The primary endpoint was the increase of ECIPE score at M6 of more than 20%. RESULTS: A total of 263 patients were included in 19 centres (male:40%; median age:30.8; Crohn's disease [CD]:73%). Of these, 133 patients were randomised into the educated group and 130 into the control group. The median relative increase in ECIPE score at M6 was higher in the educated group as compared with the control group (16.7% [0-42.1%] vs 7% [0-18.8%], respectively, p = 0.0008). The primary endpoint was met in 46% vs 24% of the patients in the educated and control groups, respectively [p = 0.0003]. A total of 92 patients met the primary endpoint. In multivariate analysis, predictors of an increase of at least 20% of the ECIPE score were randomisation in the educated group (odds ratio [OR] = 2.59) and no previous surgery [OR = 1.92]. CONCLUSIONS: These findings support the set-up of education programmes in centres involved in the management of IBD patients.

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] [pâ =â 0.001], 0.607 [±0.043] [pâ =â 0.001], and 0.782 [±0.064][pâ =â 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.

Our knowledge of COVID-19 is changing and evolving rapidly, with novel insights and recommendations, almost on a daily basis. It behooves the medical community to provide updated information on a regular basis, on best practice to facilitate optimal care of infected patients and on appropriate advice for the general population. This is particularly important in the case of patients with chronic conditions, such as inflammatory bowel disease [IBD]. In this review, we have compiled existing evidence on the impact of COVID-19 in IBD patients and provide guidance on the most appropriate care to adopt during the pandemic. Our review highlights that IBD, per se, is not a risk factor for COVID-19. However, all IBD patients with symptoms should be tested for SARS-CoV-2 and the procedures for disease management should be carefully adapted: [i] in SARS-CoV-2-positive IBD patients, medical treatments should be re-evaluated [with a particular focus on corticosteroids] always with the purpose of treating active disease and maintaining remission; [ii] non-urgent surgeries and endoscopic procedures should be postponed for all patients; [iii] online consultancy should be implemented; and [iv] hospitalization and surgery should be limited to life-threatening situations.

The coronavirus 2019 [COVID-19] pandemic has posed challenges in the routine care of patients with inflammatory bowel disease [IBD]. One of the key challenges is quantification of the risks of immunosuppressive and biological therapies in IBD patients during the pandemic. The similarities and differences between previous coronavirus outbreaks and the pathobiology of the infections can give useful information in understanding the risks, and perhaps potential beneficial aspects of drugs used in IBD. Although clinical, immunological and pharmacological data from the experience with previous coronavirus outbreaks cannot be automatically translated to predict the safety of IBD therapies during the COVID-19 pandemic, the signals so far from these outbreaks on IBD patients who are on immunomodulators and biologics are reassuring to patients and clinicians alike.

BACKGROUND: Standard high-volume polyethylene glycol [PEG] bowel preparations [PEG-4L] are recommended for patients with inflammatory bowel disease [IBD] undergoing colonoscopy. However, low-volume preparations [≤2 L of active volume] are often used in clinical practice. The aim of this study was to evaluate the efficacy, tolerability, and safety of the various bowel preparations for patients with IBD, including low-volume preparations. METHODS: We conducted a French prospective multicentre observational study over a period of 1 month. Patients aged 18-75 years with IBD with an indication of colonoscopy independent of the study were enrolled. The choice of the preparation was left to the investigators, as per their usual protocol. The patients' characteristics, disease, and colonoscopy characteristics were recorded, and they were given self-reported questionnaires. RESULTS: Twenty-five public and private hospitals enrolled 278 patients. Among them, 46 had a disease flare and 41 had bowel stenoses. Bowel preparations for colonoscopy were as follows: 42% received PEG-2L, 29% received sodium picosulfate [Pico], 15% received PEG-4L, and 14% had other preparations. The preparation did not reach the Boston's score efficacy outcome in the PEG-4L group in 51.2% of the patients [p = 0.0011]. The preparation intake was complete for 59.5% in the PEG-4L group, compared with 82.9% in the PEG-2L group and 93.8% in the Pico group [p < 0.0001]. Tolerability, as assessed by the patients' VAS, was significantly better for both Pico and PEG-2L compared with PEG-4L, and better for Pico compared with PEG-2L [p = 0.008; p = 0.0003]. In multivariate analyses, low-volume preparations were independent factors of efficacy and tolerability. Adverse events occurred in 4.3% of the patients. CONCLUSIONS: Preparations with PEG-2L and Pico were equally safe, with better efficacy and tolerability outcomes compared with PEG-4L preparations. The best efficacy/tolerance/safety profile was achieved with the Pico preparation.

BACKGROUND: IBD diagnosed after the age of 60 is increasing. Data on post-operative complications in elderly onset IBD are scarce. AIM: To describe the incidence of and factors associated with post-operative complications in elderly onset IBD, diagnosed after the age of 60. METHODS: Using EPIMAD Cohort (1988-2006), among 841 incident IBD patients, 139 (17%) underwent intestinal surgery, including 100 Crohn's disease (CD) and 39 ulcerative colitis (UC). RESULTS: After a median post-operative follow-up of 6 years (2-10), 50 (36%) patients experienced at least 1 complication with a total of 69. During the first 30 post-operative days, the mortality rate was 4%. Thirty-two early complications (<30 days) were observed in 23 patients (17%), with 15 infectious, without significant difference between CD and UC. More than half early post-operative complications (n = 19, 59%) were severe (>grade 2) without significant difference between CD and UC (P = 0.28). Thirty-seven long-term adverse effects of surgical therapy (≥30 days) were observed in 33 patients (24%). Multivariate analysis found (1) acute severe colitis (OR = 7.84 [2.15-28.52]) and emergency surgery (OR = 4.46 [1.75-11.36]) were associated with early post-operative complications, and (2) Female gender (HR = 2.10 [1.01-4.37]) and delay before surgery >3 months (HR = 2.09 [1.01-4.31]) with long-term adverse effects of surgical therapy. CONCLUSIONS: One-third of elderly IBD patients experienced at least 1 post-operative complication. Half of the early complications were severe, and infectious. Emergency surgery was the key driver for post-operative complication.

Introduction: A new clinician-administered inflammatory bowel disease (IBD) Disability Index (IBDDI) was recently developed and validated among a population in France. We aimed to validate the IBDDI in a North American setting and adapt for use as a self-report tool. Methods: Persons 18-65 years old from the population-based University of Manitoba IBD Research Registry were mailed a self-administered survey. This survey included the IBDDI and several scales that should correlate with a disability measure- the World Health Organization (WHO) Disability Assessment Scale (WHODAS) 2.0, Work and Social Adjustment Scale (WSAS), the Inflammatory Bowel Disease Questionnaire (IBDQ), and the K6-Kessler Emotional Distress Scale. We used Pearson correlation coefficients to assess construct validity, Cronbach's alpha to assess internal consistency, and Factor analysis to assess which of the IBDDI items likely belonged to a single IBD-related disability factor. Results: In response to the survey request,1143 (46% of those contacted) participated (61% female, mean age 51, 52% with Crohn's disease). On an index scale from 0-100, 14% had a score ≥50 (extreme disability, 18% of those with Crohn's disease; 10% of those with ulcerative colitis). There were strong correlations between IBDDI and WSAS (0.76), WHODAS (0.76), K6 (0.73), and an inverse correlation with IBDQ (-0.86). The Cronbach's alpha was high (0.88). All but 2 items (number of liquid stools in the past week and arthritis/arthralgia) of the 14 identified for IBDDI loaded highly onto a single factor (factor loading > 0.40). Conclusions: The findings support the validity of this new self-report version of the IBDDI as a sound measure of disability in IBD.

BACKGROUND: The correlation between vedolizumab trough levels during induction therapy and mucosal healing remains unknown. AIM: To compare early vedolizumab trough levels in patients with and without mucosal healing within the first year after treatment initiation. METHODS: We prospectively collected vedolizumab trough levels in all inflammatory bowel disease patients at weeks 2, 6 and 14 of vedolizumab treatment in three French referral centres between 1 June 2014 and 31 March 2017. Results of every patient that underwent mucosal assessment by magnetic resonance imaging and/or endoscopy in the first year after treatment initiation were analysed. RESULTS: Median vedolizumab trough levels in the overall population (n = 82) were 27 µg/mL (interquartile range, IQR 21.2-33.8 µg/mL) at week 2, 23 µg/mL (IQR 15-34.5 µg/mL) at week 6 and 10.7 µg/mL (IQR 4.6-20.4 µg/mL) at week 14. Only median vedolizumab trough levels at week 6 differed between patients with and without mucosal healing within the first year after treatment initiation (26.8 vs 15.1 µg/mL, P = 0.035). A cut-off trough level of 18 µg/mL at week 6 predicted mucosal healing within the first year after the start of vedolizumab with an area under the receiver operating curve of 0.735 (95% confidence interval 0.531-0.939). A vedolizumab trough level above 18 µg/mL at week 6 was the only independent variable associated with mucosal healing within the first year of treatment (odds ratio 15.7, 95% confidence interval 2.4-173.0, P = 0.01). CONCLUSION: Early therapeutic drug monitoring might improve timely detection of vedolizumab-treated patients in need for an intensified dosing regimen.

BACKGROUND: Several novel compounds are being developed for inflammatory bowel diseases (IBD). In addition, biosimilar drugs are being approved. An increasing number of head-to-head, superiority and non-inferiority trials in patients with IBD are expected in the future. The clinical relevance of the magnitude of the effect size is often debated. AIM: To better understand physicians' perspectives on the clinical meaningfulness of IBD trial results. METHODS: We conducted an online survey among all IOIBD (International Organization for the Study of Inflammatory Bowel Diseases) members, asking their opinion on the clinical relevance of the results of IBD trials. RESULTS: Forty-six IOIBD members responded to the survey (52.3%). In biologic-naïve ulcerative colitis (UC) and Crohn's disease (CD) patients, most of the participants considered a 15% difference with placebo for clinical remission and endoscopic remission to be clinically relevant. In head-to-head trials, most of participants considerer a 10% difference between groups for clinical remission and endoscopic remission to be clinically relevant. Half of respondents considered 10% to be an adequate margin in non-inferiority trials. In bioequivalence studies, most of the participants considered adequate a ± 5% difference between a biosimilar and the originator for pharmacokinetic parameters, efficacy, safety and immunogenicity. Regarding safety, the difference between two drugs considered clinically relevant varied from 1% to 5%, depending on the type of adverse event. CONCLUSIONS: This is the first survey exploring how physicians perceive IBD trial results, providing an estimation of the magnitude of the difference between treatment arms that may directly influence clinical practice.

BACKGROUND: Long-term outcome of ustekinumab in Crohn's disease (CD) has not been evaluated. AIM: To evaluate the long-term efficacy and safety of ustekinumab and identify the predictive factors of ustekinumab failure-free persistence in a cohort of anti-TNF refractory CD patients. METHODS: We performed a retrospective multicentre cohort study including all consecutive CD patients who began subcutaneous ustekinumab and presented a clinical response (defined as a significant improvement of CD-related clinical symptoms assessed by the patient's physician leading to continued ustekinumab) during the first year of treatment. Primary outcome was treatment failure defined as withdrawal of treatment due to loss of response, intolerance or need for surgery. RESULTS: Eighty-eight of the 122 (72%) CD patients beginning ustekinumab from March 2011 to December 2014, responded to ustekinumab and were followed up until November 2016. Median time on ustekinumab was 26.6 (13.4-34.4) months. Forty-seven patients (54%) continued ustekinumab with a clinical response and 38 (43%) stopped treatment (32 for failure, five for remission and one for pregnancy). Endoscopic response was observed in 82% of patients with endoscopic evaluation and mucosal healing in 39%. Ustekinumab failure-free persistence rates were 78% at 12 months, 66% at 24 months and 55% at 36 months. No predictive factor of ustekinumab failure-free persistence was identified. One severe adverse event was observed (anal adenocarcinoma). CONCLUSION: In this cohort of refractory CD patients receiving long-term ustekinumab therapy, more than 50% of patients continued ustekinumab treatment with no loss of response, intolerance or surgery and with a good safety profile.

BACKGROUND: The effectiveness of vedolizumab as a treatment for extraintestinal manifestations (EIM) is questionable due to its gut-specificity. AIM: To assess effectiveness of vedolizumab for EIM in patients with inflammatory bowel disease (IBD) in a large real-life experience cohort. METHODS: Between June and December 2014, 173 patients with Crohn's disease and 121 with ulcerative colitis were treated with vedolizumab. Patients were followed until week 54. EIM activity was assessed at weeks 0, 6, 14, 22, 30 and 54 by using a 3-step scale: complete remission, partial response and no response. RESULTS: At baseline, 49 (16.7%) patients had EIMs of which 47 had inflammatory arthralgia/arthritis, four had cutaneous lesions and two had both rheumatologic and skin EIM. At week 54, 21 (44.7%) patients had complete remission for inflammatory arthralgia/arthritis and three (75%) for cutaneous EIM. In multivariate analysis, complete remission of inflammatory arthralgia/arthritis was associated with clinical remission of IBD (OR = 1.89, IC95% [1.05-3.41], P = .03) and recent onset of inflammatory arthralgia/arthritis (OR = 1.99, IC95% [1.12-3.52], P = .02). During the follow-up period, 34 (13.8%) patients without any EIM at baseline, developed incident cases of inflammatory arthralgia/arthritis consisting mostly of peripheral arthralgia without evidence of arthritis and 14 (4.8%) incident cases of paradoxical skin manifestation. CONCLUSION: Vedolizumab therapy is commonly associated with improvement in EIM. This was associated with quiescent IBD and recent EIM. However, paradoxical skin manifestation and inflammatory arthralgia/arthritis may occur upon vedolizumab therapy.
