Abstract Background The association between inflammatory bowel disease (IBD) and dementia remains uncertain. We aim to investigate whether IBD is associated with higher dementia risk. Methods Using multivariable Cox regression models, we analyzed the onset of all-cause dementia among 497,775 participants, including 5778 IBD patients in the UK Biobank as primary analysis. In secondary analysis, we further examined the difference in brain structure and cognitive function changes between IBD and non-IBD individuals. The diagnosis of IBD and dementia was confirmed with combination of primary care data, hospital inpatient data, death registry, and self-report data. Brain structure was measured by brain MRI as anatomic and tissue-specific volumes; cognitive function was tested in terms of reaction, visual episodic memory, verbal-numerical reasoning, and prospective memory. Results During a mean follow-up of 11.58 years, 100 and 6709 incident all-cause dementia with or without IBD were documented, respectively. In multivariable Cox regression model, hazard ratio for incident dementia among IBD patients was 1.14 (95% confidence interval [CI], 0.94-1.39; P=.182) comparing with non-IBD participants; no statistically significant difference was observed in their brain MRI measures of anatomic and tissue-specific volumes, whereas IBD patients had a significantly increased reaction time (β=12.32; 95% CI, 1.97, 22.67; P = .020). Results of subgroup and sensitivity analyses were consistent with the main analysis. Conclusions Our study does not support a significant association between IBD and dementia. Further studies with better design and longer follow-up are needed to elucidate the association.

Abstract Background Previous studies suggested that patients with autoimmune hepatitis (AIH) and inflammatory bowel disease (IBD) have poorer outcomes; however, the significance of this association is limited. Aims To describe the phenotype of AIH-associated IBD and assess the impact of IBD on the response to treatment and risk of adverse liver outcomes in patients with AIH. Methods In our retrospective cohorts, we identified patients with concomitant diagnoses of IBD and a definite AIH. The comparison cohort consisted of AIH patients matched by gender, age at diagnosis, ethnicity, and time to follow-up. Chi-square and Mann-Whitney tests were used to assess differences. Univariate analysis was performed using the Cox proportional hazards model. Results We identified a total of 16 patients (9 males, 56.3%) with AIH-associated IBD from a cohort of 6006 IBD patients (0.27%) and 357 AIH patients (4.5%). All patients were Caucasians. Twelve patients (75.0%) had ulcerative colitis with a pancolonic extent; 4 (25.0%) – Crohn’s disease: one patient had ileitis, three – ileocolitis with one having stricturing and fistulising gastroduodenal, ileocolonic and perianal disease. The median age at IBD diagnosis was 26.5 years old and varied from 2 to 53. The age at AIH diagnosis ranged from 7 to 59 years old (median 21.1) and median follow-up time was 11.1 years ranging from 11 days to 35.2 years. The matching cohort of 113 AIH-IBD- patients was comparable to the AIH-IBD+ cohort by gender (44 males, 38.9%; p=0.188), age at diagnosis (median 28.4, IQR 32; p=0.442), ethnicity, and the follow-up time (median 8.7 years, IQR 10.2; p=0.764). There was no difference in AST, ALT and ALP at diagnosis. Complete response rates were similar in AIH-IBD+ and AIH-IBD- groups (50.0% vs. 53.1%; p=0.816). The risk of developing cirrhosis and a median time to its onset did not differ significantly: 28.6% vs. 31.0% (p=0.853) and 11.8 vs. 8.2 years (p=0.359), respectively. In univariate Cox regression, IBD was not a predictor of progression to cirrhosis (HR 0.45; 95% CI 0.13–1.50; p=0.192). The risk of developing decompensation and a median time was also comparable between groups: 21.4% vs. 33.0% (p=0.384) and 18.4 vs. 9.8 years (p=0.053), supported by the Cox regression analysis (HR 0.44; 95% CI 0.13–1.48; p=0.187). The presence of IBD was not associated with higher need in liver transplant (18.8% vs. 30.1%; p=0.348), median time was slightly shorter (1.48 vs. 4.73 years; p=0.542), also evidenced by Cox regression (HR 1.40; 95% CI 0.42–4.65; p=0.578). The risk of liver-related death was also not different among the two groups (6.3% vs. 4.4%; p=0.746), and IBD was not a predictor of it (HR 1.94; 95% CI 0.17–21.69; p=0.589). Conclusions The presence of IBD in patients with AIH is rare and do not identify a subgroup of patients with worse response to treatment or poor clinical outcomes. Funding Agencies AbbVie

Antidepressant Use

Background and Aims. Mood may have an important role in the natural history of inflammatory bowel disease (IBD). However, the impact of antidepressant use on prognosis is unknown. We aimed to address this in a longitudinal study in a referral population. Methods. We collected demographic data, clinical disease activity and mood using validated questionnaires, and antidepressant use at baseline. Longitudinal disease activity was defined by disease flare or need for glucocorticosteroids, escalation of medical therapy, hospitalisation, or intestinal resection. We compared rates of these over a minimum period of 2 years according to antidepressant use at baseline. Results. In total, 331 patients provided complete data, of whom 54 (15.8%) were taking an antidepressant at study entry. Older age, female gender, and abnormal mood scores were associated with antidepressant use. During longitudinal follow-up, there was a trend towards lower rates of any of the four endpoints of IBD activity of interest in patients with abnormal anxiety scores at baseline and who were receiving an antidepressant (42.3% versus 64.6%, P = 0.05). Based on univariate Cox regression analysis, there was a trend towards lower rates of escalation of medical therapy among patients receiving antidepressants at baseline (hazard ratio (HR) = 0.59; 95% confidence interval (CI) 0.35-1.00, P = 0.05). None of the differences observed persisted after multivariate Cox regression. Conclusions. Antidepressants may have some beneficial effects on the natural history of IBD, but larger studies with longer follow-up are required. Whether these effects are limited to patients with abnormal mood remains uncertain.

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.

Mucocutaneous Symptoms

Background: Anti-tumor necrosis factor (TNF) agents are increasingly used for rheumatic diseases and inflammatory bowel disease (IBD), but are associated with the development of anti-TNF-induced lupus (ATIL). Nonetheless, few ATIL studies on non-Caucasian IBD patients exist. Here, we investigated the incidence, clinical features, and risk factors of ATIL in Korea. Methods: We retrospectively reviewed the medical records of IBD patients undergoing anti-TNF therapy at our tertiary IBD center between 2008 and 2020. ATIL was diagnosed as a temporal association between symptoms and anti-TNF agents, and the presence of at least one serologic and non-serologic American College of Rheumatology criterion. The risk factors for ATIL occurrence were assessed using multivariate Cox regression analysis. Results: Of 1362 IBD patients treated with anti-TNF agents, 50 (3.7%) ATIL cases were suspected, of which 14 (1.0%) received a definitive diagnosis. Arthritis and mucocutaneous symptoms were observed in 13 and 4 patients, respectively. All ATIL cases were positive for anti-nuclear and anti-dsDNA antibodies. Four patients (30.8%) improved while continuing anti-TNF therapy. At the final follow up, the ATIL group ( n = 14) had a lower IBD remission rate (30.8% versus 68.8%, p = 0.019) than the non-ATIL group ( n = 36). Ulcerative colitis and longer disease duration were associated with ATIL occurrence, with hazard ratios of 7.017 ( p = 0.005) and 1.118 ( p = 0.002), respectively. Conclusion: Although rare, ATIL is associated with poor treatment response to IBD in Korean patients. ATIL should be considered if arthritis and mucocutaneous symptoms develop during anti-TNF therapy for IBD.

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

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.
