BACKGROUND:Inflammatory bowel disease (IBD) management has become increasingly complex, and education varies across fellowship programs. IBD 101 was designed to introduce first-year gastroenterology (GI) fellows to IBD care and training. METHODS:In 2019, a cohort of fellows participated in a 1-day course with small group learning and group observed structured clinical examinations. Pre- and postcourse surveys were administered to evaluate the course. To assess the long-term impact, surveys were emailed in May 2022 to all third-year fellows from previously participating programs. The primary outcome was comfort managing IBD scenarios and information regarding each fellow's exposure to IBD education. RESULTS:Fifty-five fellows from 32 programs participated. A total of 49 (89%) of 55 completed pre- and postcourse surveys. All fellows agreed that the course content was appropriate. In the postcourse survey, all fellows reported increased comfort managing IBD patients. Ninety-six percent of attendees stated that they would strongly recommend this course. Thirty-six fellows completed surveys in 2022, 21 (58%) attendees and 15 (42%) nonattendees. Attendees reported equivalent or higher levels of comfort compared with nonattendees. Higher global competence was noted among attendees (odds ratio, 5.21; 95% confidence interval, 0.91-29.9; P = .06) after adjusting for presence of a local IBD specialist, number of IBD patients seen monthly (≤5 vs >5), and rotation through an IBD service. CONCLUSIONS:IBD 101, an introductory course for first-year GI trainees, was associated with increased comfort managing IBD with a durable benefit independent of individual access to IBD education. Continuation of this program will further enhance the IBD education of future GI fellows.

PURPOSE OF REVIEW/OBJECTIVE:There is an unmet need to adequately identify, describe and treat the musculoskeletal manifestations of patients with inflammatory bowel disease (IBD). At the 2024 SPARTAN annual meeting, we reviewed the current literature on the prevalence and presentation of spondyloarthritis in patients with IBD and discussed screening strategies to select symptomatic patients for further study. The primary goal is to improve understanding and recognition of spondyloarthritis in this patient population. RECENT FINDINGS/RESULTS:In a unique collaboration between U.S. gastroenterologists and rheumatologists, the Gastroenterology and Rheumatology assessment of Spondyloarthritis in Inflammatory Bowel Disease (GRaSp-IBD) study group designed and executed a multi-center study across six institutions that applied a hybrid screening tool to identify patients with musculoskeletal symptoms suggestive of spondyloarthritis. The data was analyzed for confirmed rheumatic disease, treatment history, patient and IBD characteristics. Of the patients that screened positive, the majority (69%) had not seen a rheumatologist within the past year. IBD phenotype did not seem to increase the risk of a positive screen, but a higher number of biologic exposures proved significant. IBD patients report musculoskeletal pain at a high rate but a minority of these patients are seen by rheumatologists. Further study is needed to determine how to optimize screening for IBD arthritis, and to improve referral rates and clinical outcomes.

BACKGROUND/AIM/OBJECTIVE:Spondyloarthritis (SpA), the most common extra-intestinal manifestation of inflammatory bowel disease (IBD), is reported in up to 39% of patients with IBD. Despite this high prevalence, risk factors for developing SpA in patients with IBD are not well described. In this study, we aimed to determine the factors associated with SpA symptoms and their prevalence in an IBD cohort. METHODS:Two validated screening questionnaires for the detection of SpA in IBD (DETAIL = DETection of Arthritis in Inflammatory boweL diseases, IBIS-Q = IBD Identification of Spondyloarthritis Questionnaire) were administered to IBD patients without a prior diagnosis of SpA in six US academic medical centers. Demographic data, IBD characteristics, and medication history were recorded. RESULTS:Screening questionnaires were completed by 588 patients (220 ulcerative colitis, 349 Crohn's disease, 19 IBD-unclassified) with a median age 40 years (IQR 30 - 53) and median disease duration of 12 years (IQR 6 - 22). The number of positive screens was 130 (22%) for DETAIL, 196 (33%) for IBIS-Q and 204 (35%) for either DETAIL or IBIS-Q. Age, female sex, history of smoking, prior bowel surgery, and history of any biologic or targeted small molecule exposure were associated with a positive screen on univariate analysis (Table 1). After multivariate analysis, female sex (OR 2.03; 95% CI 1.41-2.93), older age (OR 1.02; 95% CI 1.01-1.04), history of smoking (OR 1.67; 95% CI 1.04-2.69), and history of any biologic or targeted small molecule exposure (OR 2.27; 95% CI 1.34-3.84) were independently associated with positive screens. Higher number of biologic exposures was associated with higher risk of positive screens, with the highest risk seen with three or more exposures (OR 3.25; 95% CI 1.75-6.03). CONCLUSION/CONCLUSIONS:A substantial number of IBD patients screen positive for SpA symptoms, indicating a potentially high burden of undiagnosed illness. Factors associated with SpA symptoms include older age, female sex, and more severe disease (based on increased number advanced therapies or prior surgery), whereas IBD phenotype does not independently increase the risk of a positive SpA screen. Further studies are needed to confirm these findings and better characterize SpA in IBD.

OBJECTIVE:Spondyloarthritis (SpA) is the most common extraintestinal manifestation of inflammatory bowel disease (IBD). The application of screening tools to detect SpA in patients with IBD may lead to earlier recognition of SpA and affect treatment decisions. METHODS:A combination of two previously described SpA screening questionnaires, the Detection of Arthritis in Inflammatory Bowel Disease (DETAIL) and IBD Identification of Spondyloarthritis Questionnaire (IBIS-Q), was administered to consecutive patients with IBD attending IBD specialty clinics in six US academic medical centers. Demographic data, IBD, and rheumatology history were extracted by chart review. RESULTS:A total of 669 patients were analyzed. The median age was 40 years (interquartile range [IQR] 30-54) with a median disease duration of 12 years (IQR 6-22) and moderate to severe IBD based on medication exposure and history of bowel surgery. A total of 81 patients (12%) carried a diagnosis of an inflammatory rheumatic disease, whereas 75 (11%) had consulted a rheumatologist during the previous year. Using published cutoffs, 180 out of 669 patients (27%) screened positive with DETAIL, 266 (40%) with IBIS-Q, and 275 (41%) with either questionnaire. Axial symptoms were more frequently reported than peripheral musculoskeletal complaints. Notably, 189 out of 275 (69%) screen-positive patients had neither a documented inflammatory rheumatic disease diagnosis nor a visit with a rheumatologist within the past year. CONCLUSION/CONCLUSIONS:A substantial proportion of patients with IBD have symptoms suggestive of SpA, and many of these may have undiagnosed SpA. The IBIS-Q questionnaire appears to identify more potential SpA cases than DETAIL. Strategies are needed to prioritize rheumatology consultations for those patients with IBD who are most likely to benefit.

BACKGROUND:The prognostic significance of histology in ileal pouch-anal anastomosis (IPAA) remains unclear. The aim of this study was to evaluate if histologic variables are predictive of IPAA clinical outcomes and healthcare utilization. METHODS:This was a retrospective cohort study of patients with IPAA undergoing surveillance pouchoscopy at a tertiary care institution. Pouch body biopsies were reviewed by gastrointestinal pathologists, who were blinded to clinical outcomes, for histologic features of acute or chronic inflammation. Charts were reviewed for clinical outcomes including development of acute pouchitis, chronic pouchitis, biologic or small molecule initiation, hospitalizations, and surgery. Predictors of outcomes were analyzed using univariable and multivariable logistic and Cox regression. RESULTS:A total of 167 patients undergoing surveillance pouchoscopy were included. Polymorphonuclear leukocytes (odds ratio [OR], 1.67), ulceration and erosion (OR, 2.44), chronic inflammation (OR, 1.97), and crypt distortion (OR, 1.89) were associated with future biologic or small molecule initiation for chronic pouchitis. Loss of goblet cells was associated with development of chronic pouchitis (OR, 4.65). Pyloric gland metaplasia was associated with hospitalizations (OR, 5.24). No histologic variables were predictive of development of acute pouchitis or surgery. In an exploratory subgroup analysis of new IPAA (<1 year), loss of goblet cells was associated with acute pouchitis (OR, 14.86) and chronic pouchitis (OR, 12.56). Pyloric gland metaplasia was again associated with hospitalizations (OR, 13.99). CONCLUSIONS:Histologic findings may be predictive of IPAA outcomes. Pathologists should incorporate key histologic variables into pouchoscopy pathology reports. Clinicians may need to more closely monitor IPAA patients with significant histologic findings.

In individuals with inflammatory bowel disease (IBD), extraintestinal manifestations (EIMs) represent a significant burden of illness, with reported prevalence rates of up to 50%.¹ Of the various types of EIMs, the most commonly involved organ system is the musculoskeletal system.

BACKGROUND & AIMS:Safety of biologic agents is a key consideration in patients with inflammatory bowel disease (IBD) and active or recent cancer. We compared the safety of tumor necrosis factor (TNF)-α antagonists vs non-TNF biologics in patients with IBD with active or recent cancer. METHODS:We conducted a multicenter retrospective cohort study of patients with IBD and either active cancer (cohort A) or recent prior cancer (within ≤5 years; cohort B) who were treated with TNFα antagonists or non-TNF biologics after their cancer diagnosis. Primary outcomes were progression-free survival (cohort A) or recurrence-free survival (cohort B). Safety was compared using inverse probability of treatment weighting with propensity scores. RESULTS:In cohort A, of 125 patients (483.8 person-years of follow-up evaluation) with active cancer (age, 54 ± 15 y, 75% solid-organ malignancy), 10 of 55 (incidence rate [IR] per 100 py, 4.4) and 9 of 40 (IR, 10.4) patients treated with TNFα antagonists and non-TNF biologics had cancer progression, respectively. There was no difference in the risk of progression-free survival between TNFα antagonists vs non-TNF biologics (hazard ratio, 0.76; 95% CI, 0.25-2.30). In cohort B, of 170 patients (513 person-years of follow-up evaluation) with recent prior cancer (age, 53 ± 15 y, 84% solid-organ malignancy; duration of remission, 19 ± 19 mo), 8 of 78 (IR, 3.4) and 5 of 66 (IR 3.7) patients treated with TNFα antagonists and non-TNF biologics had cancer recurrence, respectively. The risk of recurrence-free survival was similar between both groups (hazard ratio, 0.94; 95% CI, 0.24-3.77). CONCLUSIONS:In patients with IBD with active or recent cancer, TNFα antagonists and non-TNF biologics have comparable safety. The choice of biologic should be dictated by IBD disease severity in collaboration with an oncologist.

BACKGROUND/UNASSIGNED:The COVID-19 pandemic led to the urgent implementation of telehealth visits in inflammatory bowel disease (IBD) care; however, data assessing feasibility remain limited. OBJECTIVES/UNASSIGNED:We looked to determine the completion rate of telehealth appointments for adults with IBD, as well as to evaluate demographic, clinical, and social predictors of incomplete appointments. DESIGN/UNASSIGNED:We conducted a retrospective analysis of all patients with IBD who had at least one scheduled telehealth visit at the NYU IBD Center between 1 March 2020 and 31 August 2021, with only the first scheduled telehealth appointment considered. METHODS/UNASSIGNED:Medical records were parsed for relevant covariables, and multivariable logistic regression was used to estimate the adjusted association between demographic factors and an incomplete telehealth appointment. RESULTS/UNASSIGNED: = 0.22). After adjustment, patients with CD had higher odds of an incomplete appointment as compared to patients with UC [adjusted odds ratio (adjOR): 1.37, 95% confidence interval (CI): 1.10-1.69], as did females (adjOR: 1.26, 95% CI: 1.04-1.54), and patients who had a non-first-degree relative listed as an emergency contact (adjOR: 1.69, 95% CI: 1.16-2.44). While age ⩾60 years was not associated with appointment completion status, we did find that age >80 years was an independent predictor of missed telehealth appointments (adjOR: 2.92, 95% CI: 1.12-7.63) when compared to individuals aged 60-70 years. CONCLUSION/UNASSIGNED:telehealth, particularly those aged 60-80 years, may therefore provide an additional venue to complement in-person care.

BACKGROUND:There is little data regarding the risk of new or recurrent cancer in patients with inflammatory bowel disease (IBD) and a prior history of cancer who are exposed to ustekinumab or vedolizumab. We assessed the risk of subsequent cancer in patients exposed to these agents. METHODS:We performed a retrospective cohort study of patients with IBD and a history of cancer at an academic medical center between January 2013 and December 2020. We collected data on demographics, IBD and cancer disease characteristics, and drug exposures. The primary exposure was immunosuppressive therapy after diagnosis of cancer. The primary outcome was interval development of new or recurrent cancer. RESULTS:Of 390 patients with IBD and a previous history of cancer, 37 were exposed to vedolizumab, 14 ustekinumab, 41 antitumor necrosis factor (anti-TNF), and 31 immunomodulator; and 267 were not exposed to immunosuppression following cancer diagnosis. During a total median follow-up time of 52 months, 81 (20%) patients developed subsequent cancer: 6 (16%) were exposed to vedolizumab, 2 (14%) to ustekinumab, 3 (10%) to immunomodulators, 12 (29%) to anti-TNF, and 56 (21%) with no immunosuppression (P = .41). In a multivariable Cox model adjusting for age, IBD subtype, smoking, cancer recurrence risk, and cancer stage, there was no increase in subsequent cancer with vedolizumab (adjusted hazard ratio, 1.36; 95% CI, 0.27-7.01) or ustekinumab (adjusted hazard ratio, 0.96; 95% CI, 0.17-5.41). Patients with more than 1 biologic exposure also did not have an increased risk of subsequent cancer. CONCLUSIONS:Exposure to ustekinumab or vedolizumab in patients with IBD and a prior history of cancer does not appear to be associated with an increased risk of subsequent new or recurrent cancer.

Introduction: The care of inflammatory bowel disease (IBD) has become increasingly complex and specialized. IBD education of gastroenterology (GI) trainees needs improvement and standardization. IBD 101, an annual course designed to introduce first-year GI fellows to various clinical topics in the management of IBD, was held on September 14, 2019. In this inaugural program, a select group of fellows (N=55 from 32 different programs) participated in a one-day course involving small group didactic sessions and Group Observed Structured Clinical Examinations (OSCEs) led by expert faculty members in seven clinical topics.
Method(s): To assess the long-term impact of IBD 101, email surveys were administered in May 2022 (the graduating year of the inaugural IBD 101 cohort) to all third-year GI fellows from participating programs, inclusive of both attendees and non-attendees. The primary outcome was comfort level discussing the 7 topics addressed at IBD 101, graded using a Likert scale (15 "strongly disagree" to '45 "strongly agree"). Information regarding each fellow's exposure to IBD education was collected.
Result(s): Thirty-six fellows completed surveys, of whom 21 (58%) were IBD 101 attendees and 15 (42%) were non-attendees. Overall, attendees reported equivalent or higher levels of comfort in each of the 7 topics than did non-attendees (Figure). In particular, a higher proportion of attendees strongly agreed with comfort in discussing pregnancy and IBD (43% vs. 13%; P=0.04) and loss of response to biologics (62% vs. 27%; P=0.13) than non-attendees. When assessing overall confidence, 76% of attendees reported comfort in all 7 categories, compared with 53% of non-attendees (P=0.15). Attending IBD 101 was associated with overall confidence (OR 5.21 [95% CI 0.91-29.9]; P=0.06) even after adjusting for presence of an IBD specialist at a fellow's home institution, number of IBD patients seen per month (<=5 vs. >5) and rotating through an IBD-only clinic or inpatient service (Table).
Conclusion(s): IBD 101, a primer for first-year GI trainees, was associated with increased comfort in the management of IBD, with more pronounced impact on challenging topics. IBD 101 is a valuable learning opportunity for first-year GI fellows with a durable benefit independent of individual access to IBD education, and we plan continued development, expansion and assessment of this program in collaboration with the ACG to further enhance the IBD education of the pipeline of GI trainees.
