Abstract
BACKGROUND Recruitment for randomized controlled trials [RCTs] in inflammatory bowel diseases [IBD] has substantially dropped over time. This study aimed to assess reasons why IBD patients are not included in sponsored multicentre phase IIb-III RCTs. METHODS All IOIBD members [n = 58] were invited to participate. We divided barriers to participation as follows: [1] reasons patients with active IBD were not deemed appropriate for an RCT; [2] reasons qualified patients did not wish to participate; and [3] reasons for screen failure [SF] in patients agreeing to participate. We assess these in a 4-week prospective study including, consecutively, all patients with symptomatic disease for whom a treatment change was required. In addition, we performed a 6-month retrospective study to further evaluate reasons for SF. RESULTS A total of 106 patients (60 male [56.6%], 63 Crohn's disease [CD] [59.4%]), from ten centres across the world, were included in the prospective study. An RCT has not been proposed to 65 of them [mainly due to eligibility criteria]. Of the 41 patients to whom an RCT was offered, eight refused [mainly due to reluctance to receive placebo] and 28 agreed to participate. Among these 28 patients, five failed their screening and 23 were finally included in an RCT. A total of 107 patients (61 male [57%], 67 CD [62.6%]), from 13 centres worldwide, were included in our retrospective study of SFs. The main reason was insufficient disease activity. CONCLUSION This first multicentre study analysing reasons for non-enrolment in IBD RCTs shows that we lose patients at each step. Eligibility criteria, the risk of placebo assignment, and insufficient disease activity were part of the main barriers.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) can have an impact on pregnancy outcomes due to the effect of the disease activity and medication use. This study aimed to evaluate the pregnancy outcomes in IBD patients treated at a multidisciplinary clinic. METHODS This study was a retrospective cohort study including consecutive pregnant patients with IBD having a singleton gestation attending a multidisciplinary clinic between 2012 and 2019. The IBD activity and management throughout gestation were assessed. The pregnancy outcomes included: adverse neonatal and maternal outcomes, mode of delivery, and three integrative outcomes: (1) a favorable pregnancy outcome, (2) a poor pregnancy outcome, and (3) an unfavorable maternal outcome. The IBD pregnant cohort was compared with a cohort of non-IBD pregnant women delivering at the same shift. Multivariable logistic regression was used for risk assessment. RESULTS Pregnant women with IBD (141) and without (1119) were included. Mean maternal age was 32 [±4] years. Patients with IBD had a higher rate of nulliparity (70/141 (50%) vs. 340/1119 (30%), p < 0.001) and lower BMI (21.42 kg/m2 (19.18-23.44) vs. 22.48 (20.31-25.59), p = 0.002). All the other characteristics were comparable. Most patients with IBD 124/141 (88%) were in clinical remission at conception; with maintenance therapy in 117/141 patients (83%). A third of the patients, 43/141 (30.5%), were treated with biologics. Exacerbation occurred during pregnancy in 51/141 (36%). The majority of the maternal and neonatal outcomes and all the composite outcomes were comparable between the patients with IBD and the women without IBD. Cesarean delivery was more frequent in patients with IBD (49/141 (34.8%) vs. 270/1119 (24.1%), p = 0.021). IBD was not associated with composite outcomes. CONCLUSIONS In pregnant patients with IBD followed at a multidisciplinary clinic, the pregnancy outcomes were encouraging and comparable to those of the women without IBD.

Abstract
BACKGROUND AND AIMS Patients with inflammatory bowel disease [IBD] are often affected during their reproductive years and may have many perinatal queries that require the comprehensive perspectives of a multidisciplinary team [MDT]. The purpose of this topical review is to assess the scientific evidence and provide expert opinion related to nutritional, psychological, and supportive care of women and their infants throughout the prenatal, antenatal, and infant periods. METHODS A consensus expert panel of a paediatrician, gastroenterologists, nurses, and dietitians was convened by the European Crohn's and Colitis Organisation. This panel critically reviewed literature related to the non-medical management of patients with IBD during preconception, pregnancy, the postnatal period, and the first years of the infant's life. Statements were developed using an e-Delphi process over two rounds and were confirmed when ≥80% of experts agreed with the statements. RESULTS A total of 19 current practice positions were developed that cover the preconception period, pregnancy and lactation, and early life exposures associated with risk of IBD. Development of the infant microbiome and its role in the immune system and topics including nutritional optimization, psychological support, and education relating to early life were reviewed. CONCLUSIONS Patients with IBD have unique nutritional and psychosocial needs that may affect fertility and pregnancy outcomes. The early life environment of infants born to parents with IBD may be associated with subsequent development of IBD in offspring. A MDT is the optimal setting to support and counsel patients throughout the perinatal period.

Abstract
INTRODUCTION Regulatory agencies supported vaccination of pregnant women with SARS-CoV-2 mRNA vaccines, including patients with IBD. No data exist regarding these vaccines in IBD during pregnancy. AIM To assess the serologic response to two doses of the mRNA SARS-CoV-2 BNT162b2 vaccine in pregnant women with IBD vaccinated during pregnancy, compared to that of pregnant women without IBD, and non-pregnant women with IBD. METHODS Anti-spike antibody levels were assessed in all women and in cord blood of consenting women. RESULTS From December 2020 to December 2021, 139 women were assessed: pregnant with IBD-36, pregnant without IBD-61, and not pregnant with IBD-42. Antibodies were assessed in cords of two and nine newborns of women with and without IBD, respectively. Mean gestational ages at administration of the second vaccine doses were 22.0 weeks in IBD and 23.2 weeks in non-IBD, respectively. Mean (SD) duration from the second vaccine dose to serology analysis in pregnant women with IBD, without IBD, and in non-pregnant women with IBD was 10.6 (4.9), 16.4 (6.3), and 4.3 (1.0) weeks, respectively. All women mounted a serologic response. In multivariable analysis, no correlation was found between the specific group and antibody levels. In both pregnancy groups, an inverse correlation between antibody levels and the interval from the second vaccine dose was demonstrated. Cord blood antibody levels exceeded maternal levels in women with and without IBD. CONCLUSION All patients with IBD mounted a serologic response. The interval between vaccine administration to serology assessment was the most important factor determining antibody levels. A third vaccine dose should be considered in pregnant women with IBD vaccinated at early stages of pregnancy.

Abstract
AIMS i] To evaluate the evolution of pregnancies and offspring after inflammatory bowel disease [IBD] surgery during pregnancy; and ii] to describe the indications, the surgical techniques, and the frequency of caesarean section concomitant with surgery. METHODS Patients operated on due to IBD during pregnancy after 1998 were included. Participating clinicians were asked to review their databases to identify cases. Data on patients' demographics, IBD characteristics, medical treatments, IBD activity, pregnancy outcomes, surgery, delivery, and foetal and maternal outcomes, were recorded. RESULTS In all, 44 IBD patients were included, of whom 75% had Crohn's disease; 18% of the surgeries were performed in the first trimester, 55% in the second, and 27% in the third trimester. One patient had complications during surgery, and 27% had postsurgical complications. No patient died. Of deliveries, 70% were carried out by caesarean section. There were 40 newborns alive. There were four miscarriages/stillbirths [one in the first, two in the second, and one in the third trimester]; two occurred during surgery, and another two occurred 2 weeks after surgery; 14% of the surgeries during the second trimester and 64% of those in the third trimester ended up with a simultaneous caesarean section or vaginal delivery. Of the 40 newborns, 61% were premature and 47% had low birth weight; 42% of newborns needed hospitalisation [25% in the intensive care unit]. CONCLUSIONS IBD surgery during pregnancy remains an extremely serious situation. Therefore, surgical management should be performed in a multidisciplinary team, involving gastroenterologists, colorectal surgeons, obstetricians, and neonatal specialists.

Abstract
BACKGROUND Evidence regarding the risk of immunogenicity in patients with inflammatory bowel disease (IBD) who switched anti-tumor necrosis factor alpha (anti-TNFα) therapies to a subsequent anti-TNFα (either infliximab or adalimumab) is conflicting. We aimed to assess the risk of consecutive immunogenicity to anti-TNFα in a large cohort of patients. METHODS This was a multicenter retrospective study. Medical records of adult and pediatric IBD switchers who had pharmacokinetic data for both agents between 2014 and 2020 were retrieved. Data including age, sex, disease type, duration of therapies, and concomitant use of immunomodulators (IMMs) were recorded. RESULTS Overall, 164 patients were included [52% female; 88% Crohn's disease; mean age = 24.4 ± 14.6 years; 108 (66%) switched from infliximab to adalimumab and 56 (34%) vice versa]; 120 (73.1%) patients switched due to an immunogenic failure. Among patients switching therapy from infliximab to adalimumab due to an immunogenic failure immunogenicity to infliximab was significantly associated with consecutive immunogenicity to adalimumab (p = 0.026). Forthy four out of 120 patients (36.6%) with an immunogenic failure to the first anti-TNFα started an IMM with the second anti-TNFα. This combination with IMM was not associated with reduction of consecutive immunogenicity (p = 0.31), but it was associated with longer drug retention (p = 0.007). Multivariate analysis demonstrated that older age at second anti-TNFα, adjusted to the chronology of therapy and sex, was associated with increased immunogenicity to the second anti-TNFα. CONCLUSION Patients with IBD who switch from infliximab to adalimumab following an immunogenic failure are at increased risk for consecutive immunogenicity to adalimumab. IMM use after a switch prolongs drug retention.

Abstract
BACKGROUND AND AIMS Skin eruptions are prevalent among patients with inflammatory bowel diseases (IBD), often associated with therapies and frequently leading to dermatological consults and treatment interruptions. We aimed to assess the impact of joint shared decision-making in a multidisciplinary (MDT) IBD-DERMA clinic. METHODS This retrospective cohort study assessed a consecutive group of patients with IBD who were referred for consultation in an MDT clinic at a tertiary referral center in Israel. RESULTS Over 1 year, 118 patients were evaluated in the MDT-IBD-DERMA clinic: 68 (57.6%) males; age - 35.2 ± 13.5 years, disease duration - 7.1 (interquartile range: 3.7-13.9) years; Crohn's disease - 94/118 (79.6%). Skin eruption induced by an anti-tumor necrosis factor (TNF) were the most common diagnoses [46/118 (39%)], including psoriasiform dermatitis (PD) - 31/46 (67.4%) and inflammatory alopecia (IA) - 15/46 (32.6%). Of these, 18 patients (39.1%) continued the anti-TNF agent concomitantly with a topical or systemic anti-inflammatory agent to control the eruption. The remaining 28 patients (60.9%) discontinued the anti-TNF, of whom 16/28 (57.1%) switched to ustekinumab. These strategies effectively treated the majority [38/46 (82.6%)] of patients. Continuation of the anti-TNF was possible in a significantly higher proportion of patients with PD: 12/31 (38.7%) than only one in the IA group, p = 0.035. There was a higher switch to ustekinumab among the IA 7/15 (46.6%) compared with the PD 7/31 (22.6%) group, P = .09. Following IBD-DERMA advised intervention, IBD deteriorated in 9/4 6(19.5%) patients, 5/9 on ustekinumab (PD versus IA, P = NS). CONCLUSION Shared decision-making in an integrated IBD-DERMA clinic allowed successful control of skin eruptions while preserving control of the underlying IBD in more than 80% of cases. Patients with IA profited from a switch to ustekinumab.

Abstract
BACKGROUND & AIMS The early stages of Crohn's disease (CD) course are heterogeneous, and it is a challenge to predict the course of disease in patients with new diagnosis. METHODS We performed an observational longitudinal study of 156 adults (79 male; median age, 27.7 years; 57 treatment naïve) with newly diagnosed CD (within 6 months of enrollment), referred from medical centers and community clinics in Israel from 2013 through 2017. Study participants each received semi-annual scheduled evaluations. Indolent disease was defined as a disease course without need for strict interventions to control complicated course of CD (hospitalization or surgery, or decision to start steroid, immunomodulator, or biologic therapy). Cox regression and receiver operating characteristic analyses were used to identify factors associated with early indolent or complicated course of CD. We validated our findings in an independent cohort of patients with CD from a separate medical center in Israel in 2018. RESULTS Over a median follow-up period of 17.2 months (interquartile range, 8.8-23.8 months), 52 patients (33.3%) had an indolent course of CD, 29 (18.5%) required hospitalizations, and 75 (48%) were recommended to start steroid, immunomodulator, or biologic therapies. The median time to first intervention was 3.4 months (95% CI, 2.4-4.4). We developed a model based on clinical factors that identified 4 factors associated with complicated course in treatment-naïve patients: body mass index <25 kg/m2 (hazard ratio [HR], 2.45; 95% CI, 1.07-5.43; P = .033), serum level of vitamin B12 <350 pg/mL (HR, 2.78; 95% CI, 1.21-6.41; P = .016), white blood cells ≥7 × 103/μL (HR, 2.419; 95% CI, 1.026-5.703; P = .044), and serum level of ALT ≥25 IU/L (HR, 2.680; 95% CI, 1.186-6.058; P = .018). This model discriminated between patients with vs without a complicated course of disease with 90% and 89% accuracy at 6 and 12 months after diagnosis, respectively. A validation cohort demonstrated a discriminatory ability of 79% at 3 months after diagnosis, and a nomogram was constructed. CONCLUSIONS In an observational longitudinal study of 156 patients with newly diagnosed CD, we found that one third have an early indolent course of disease. We identified factors that can be measured at diagnosis to identify patients at risk for an early complicated course-these might be used in patient management and selection of treatment.

Abstract
BACKGROUND This European Crohn's and Colitis Organisation [ECCO] topical review focuses on the transition of adolescents with inflammatory bowel disease [IBD] from child-centred to adult-oriented care. The aim was to provide evidence-supported, expert consensus for health professionals taking part in the transition. METHODS An online survey determined the areas of importance for health professionals involved in the transition of adolescents with IBD. Thereafter an expert panel of nine paediatric and five adult gastroenterologists was formed to identify the critical elements of the transition programme, and to prepare core messages defined as 'current practice points'. There is limited literature about transition, therefore this review is mainly based on expert opinion and consensus, rather than on specific evidence. RESULTS A total of 21 practice points were generated before the first [online] voting round. Practice points that reached >80% agreement were accepted, while those that did not reach 80% agreement were refined during a consensus meeting and subjected to voting. Ultimately, 14 practice points were retained by this review. CONCLUSION We present a consensus-based framework for transitional care in IBD that provides a guidance for clinical practice.
