Abstract Background Current evidence regarding the association of serum zonulin-related proteins (ZRP) levels with prevalent inflammatory bowel disease (IBD) is contradictory. Moreover, the association with the subsequent risk of incident IBD is still unexplored. This study aimed to investigate the association of serum ZRP levels with both prevalent and incident IBD. Method The study included a total of 130 women (51–61 years) from the Women’s Health in Lund Area (WHILA) study, which included 18 prevalent IBD (diagnosed before baseline) and 47 incident IBD diagnosed during the 17 years (median) follow-up and age- and sampling time-matched controls. Serum ZRP was tested in all participants by ELISA. Results The serum ZRP levels were significantly higher in prevalent IBD compared to their matched controls (63.2 ng/ml vs 57.0 ng/ml, p = 0.02), however, no evidence of a difference in ZRP levels was found between the women who developed IBD during the follow-up period and their matched controls (61.2 ng/ml vs 59.7 ng/ml, p = 0.34). Using linear mixed models, we found that the association between serum ZRP levels and prevalent IBD (β = 6.2, p = 0.01), remained after adjusting for potential confounders. Conditional logistic regression models showed no evidence of an association between ZRP level and incident IBD (OR 1.03, p = 0.34). Conclusion Higher serum ZRP levels were associated with prevalent IBD, but not with incident IBD in our study samples.

Abstract Background The specific contribution of anti-TNF therapy to the onset of herpes zoster (HZ) in patients with inflammatory bowel disease (IBD) remains uncertain. Thus, the purpose of this nested case-control study was to explore whether the use of anti-TNF therapy is associated with an increased risk of HZ. Methods Using the Regie de l’Assurance Maladie du Québec, we identified incident cases of IBD between 1998 and 2015. We matched IBD cases of HZ with up to 10 IBD HZ-free controls on year of cohort entry and follow-up. Current use was defined as a prescription for anti-TNF therapy 60 days before the index date, with nonuse as the comparator. We conducted conditional logistic regression to estimate odds ratios (ORs) with 95% confidence intervals (CIs), adjusting for potential confounders. Results The cohort consisted of 15,454 incident IBD patients. Over an average follow-up of 5.0 years, 824 patients were diagnosed with HZ (incidence of 9.3 per 1000 person-years). Relative to nonuse, current use of anti-TNF therapy was associated with an overall increased risk of HZ (OR, 1.5; 95% CI, 1.1–2.1). The risk was increased among those older than 50 years (OR, 2.1; 95% CI, 1.2–3.6) and those additionally using steroids and immunosuppressants (OR, 4.1; 95% CI, 2.3–7.2). Conclusions Use of anti-TNF therapy was associated with an increased risk of HZ among patients with IBD, particularly among those older than 50 years and those on combination therapy. Prevention strategies for HZ ought to be considered for younger IBD patients commencing treatment.

ObjectivesElectronic health records (EHR) are receiving growing attention from regulators, biopharmaceuticals and payors as a potential source of real-world evidence. However, their suitability for the study of diseases with complex activity measures is unclear. We sought to evaluate the use of EHR data for estimating treatment effectiveness in inflammatory bowel disease (IBD), using tofacitinib as a use case.MethodsRecords from the University of California, San Francisco (6/2012 to 4/2019) were queried to identify tofacitinib-treated IBD patients. Disease activity variables at baseline and follow-up were manually abstracted according to a preregistered protocol. The proportion of patients meeting the endpoints of recent randomised trials in ulcerative colitis (UC) and Crohn’s disease (CD) was assessed.Results86 patients initiated tofacitinib. Baseline characteristics of the real-world and trial cohorts were similar, except for universal failure of tumour necrosis factor inhibitors in the former. 54% (UC) and 62% (CD) of patients had complete capture of disease activity at baseline (month −6 to 0), while only 32% (UC) and 69% (CD) of patients had complete follow-up data (month 2 to 8). Using data imputation, we estimated the proportion achieving the trial primary endpoints as being similar to the published estimates for both UC (16%, p value=0.5) and CD (38%, p-value=0.8).Discussion/ConclusionThis pilot study reproduced trial-based estimates of tofacitinib efficacy despite its use in a different cohort but revealed substantial missingness in routinely collected data. Future work is needed to strengthen EHR data and enable real-world evidence in complex diseases like IBD.

The assessment and management of patients with known, or suspected, paediatric inflammatory bowel disease (PIBD) has been hugely impacted by the COVID-19 pandemic. Although current evidence of the impact of COVID-19 infection in children with PIBD has provided a degree of reassurance, there continues to be the potential for significant secondary harm caused by the changes to normal working practices and reorganisation of services.Disruption to the normal running of diagnostic and assessment procedures, such as endoscopy, has resulted in the potential for secondary harm to patients including delayed diagnosis and delay in treatment. Difficult management decisions have been made in order to minimise COVID-19 risk for this patient group while avoiding harm. Initiating and continuing immunosuppressive and biological therapies in the absence of normal surveillance and diagnostic procedures have posed many challenges.Despite this, changes to working practices, including virtual clinic appointments, home faecal calprotectin testing kits and continued intensive support from clinical nurse specialists and other members of the multidisciplinary team, have resulted in patients still receiving a high standard of care, with those who require face-to-face intervention being highlighted.These changes have the potential to revolutionise the way in which patients receive routine care in the future, with the inclusion of telemedicine increasingly attractive for stable patients. There is also the need to use lessons learnt from this pandemic to plan for a possible second wave, or future pandemics as well as implementing some permanent changes to normal working practices.In this review, we describe the diagnosis, management and direct impact of COVID-19 in paediatric patients with IBD. We summarise the guidance and describe the implemented changes, evolving evidence and the implications of this virus on paediatric patients with IBD and working practices.

Abstract Background The relationship between older age and extraintestinal manifestations (EIMs) in patients with inflammatory bowel disease (IBD) remains unknown. Aims This study aims to determine whether older age is associated with increased risk of EIMs in IBD patients. Methods This was a retrospective study of IBD patients seen at the McMaster University Medical Centre, in Hamilton, ON, Canada from 2012–2020. Patients were identified to have the primary outcome of interest if their gastroenterologist documented the presence of any EIM either during the baseline assessment or during the period of follow up. The independent variable, age at start of follow-up, was dichotomized into two categories age >=40 vs. <40.Prior knowledge in combination with forward selection was used to develop a logistic regression model. The variables utilized for the forward selection model included gender, disease duration, and current biologic use. Results A total of 995 IBD patients (625 with CD) were considered for the regression analysis, all for whom the EIM status was recorded. Out of the 995 patients, 270 patients reported at least one EIM – 99 with arthritis/arthralgia, 79 with dermatologic manifestations, 16 with ophthalmic manifestations, 30 with liver manifestations, and 116 with other EIMs. A univariate regression analysis foundincreased odds of EIMs in older patientsas compared to younger patients (odds ratio (OR) 1.41 (95% CI, 1.05 – 1.89)). In the multivariate regression analysis, current biologic use was found to have a significant relationship with odds of having EIMs (OR 1.49; 95% CI, 1.06 – 2.09). After adjustment for biologic use, patients aged 40 or over had 1.46 times higher odds of having EIMs (95% CI 1.03 – 2.05). A sub-analysis of individual EIM categoriesdid not show a significant association with older age. Conclusions Older age is associated with increased risk of EIMs in IBD patients. Patients with EIMs were also more likely to be treated with biological therapies. Clinicians should inquire about the presence of EIMs in older IBD patients. Funding Agencies None

Diet plays a pivotal role in the onset and course of inflammatory bowel disease (IBD). Patients are keen to know what to eat to reduce symptoms and flares, but dietary guidelines are lacking. To advice patients, an overview of the current evidence on food (group) level is needed. This narrative review studies the effects of food (groups) on the onset and course of IBD and if not available the effects in healthy subjects or animal and in vitro IBD models. Based on this evidence the Groningen anti-inflammatory diet (GrAID) was designed and compared on food (group) level to other existing IBD diets. Although on several foods conflicting results were found, this review provides patients a good overview. Based on this evidence, the GrAID consists of lean meat, eggs, fish, plain dairy (such as milk, yoghurt, kefir and hard cheeses), fruit, vegetables, legumes, wheat, coffee, tea and honey. Red meat, other dairy products and sugar should be limited. Canned and processed foods, alcohol and sweetened beverages should be avoided. This comprehensive review focuses on anti-inflammatory properties of foods providing IBD patients with the best evidence on which foods they should eat or avoid to reduce flares. This was used to design the GrAID.

Abstract Background The aim of the present study was to investigate outcomes of anti-TNF-alpha (ATA) withdrawal in selected pediatric patients with inflammatory bowel disease who achieved clinical remission and mucosal and histological healing (MH and HH). Methods A retrospective analysis was performed on children and adolescents affected by Crohn disease (CD) and ulcerative colitis (UC) who were followed up at 2 tertiary referral centers from 2008 through 2018. The main outcome measure was clinical relapse rates after ATA withdrawal. Results One hundred seventy patients received scheduled ATA treatment; 78 patients with CD and 56 patients with UC underwent endoscopic reassessment. We found that MH was achieved by 32 patients with CD (41%) and 30 patients with UC (53.6%); 26 patients with CD (33.3%) and 22 patients with UC (39.3%) achieved HH. The ATA treatment was suspended in 45 patients, 24 affected by CD and 21 by UC, who all achieved concurrently complete MH (Simplified Endoscopic Score for CD, 0; Mayo score, 0, respectively) and HH. All the patients who suspended ATA shifted to an immunomodulatory agent or mesalazine. In contrast, 17 patients, 8 with CD and 9 with UC, continued ATA because of growth needs, the persistence of slight endoscopic lesions, and/or microscopic inflammation. Thirteen out of 24 patients with CD who suspended ATA experienced disease relapse after a median follow-up time of 29 months, whereas no recurrence was observed among the 9 patients with CD who continued treatment (P = 0.05). Among the patients with UC, there were no significant differences in relapse-free survival among those who discontinued ATA and those who did not suspend treatment (P = 0.718). Conclusions Despite the application of rigid selection criteria, ATA cessation remains inadvisable in CD. In contrast, in UC, the concurrent achievement of MH and HH may represent promising selection criteria to identify patients in whom treatment withdrawal is feasible.
