BACKGROUND AND AIMS/OBJECTIVE:In patients with inflammatory bowel disease (IBD) and a history of cancer, retrospective studies suggest that exposure to immunosuppressive agents does not increase the risk of incident (recurrent or new) cancer compared to unexposed patients. SAPPHIRE is a prospective registry aimed at addressing this issue. METHODS:Since 2016, patients with IBD and confirmed index cancer prior to enrollment were followed annually. Patients receiving chemotherapy or radiation at enrollment, or recurrent cancer within five years were excluded. Primary outcome was development of incident cancer related to exposure to immunosuppressive medications. RESULTS:Among 305 patients (47% male, 88% white), median age at IBD diagnosis and cancer were 32 and 52 years, respectively. Index cancers were solid organ (46%), dermatologic (32%), gastrointestinal (13%), and hematologic (9%). During median follow-up of 4.8 years, 210 (69%) were exposed to immunosuppressive therapy and 46 (15%) developed incident cancers (25 new, 21 recurrent). In unadjusted analysis, the crude rate of incident cancer in unexposed patients was 2.58/100 person-years versus 4.78/100 PY (relative risk 1.85, 95% CI 0.92-3.73) for immunosuppression exposed patients. In a proportional hazards model adjusting for sex, smoking history, age and stage at index malignancy, and non-melanoma skin cancer, no significant association was found between receipt of immunosuppression and incident cancer (adjusted hazard ratio, aHR, 1.41, 95% CI: 0.69-2.90), or with any major drug class. CONCLUSION/CONCLUSIONS:In this interim analysis of patients with IBD and a history of cancer, despite numerically elevated aHRs, we did not find a statistically significant association between subsequent exposure to immunosuppressive therapies and development of incident cancers.

BACKGROUND:Inflammatory bowel disease (IBD) is a chronic, immune-mediated inflammatory disorder of the gastrointestinal tract. In IBD, systemic inflammation and immune dysregulation may also impact extraintestinal organs, such as the thyroid gland. Despite this, little is known about the influence of concomitant hypothyroidism on the clinical course of IBD. METHODS:A retrospective analysis was conducted among adult patients with IBD and at least one thyroid stimulating hormone (TSH) measurement within a large healthcare network. Patient charts were reviewed, and baseline demographics, disease characteristics, biomarkers, healthcare utilization, medication use, and other comorbidities were extracted. Patients were stratified by those with IBD only and those with concomitant IBD and hypothyroidism. Multivariable logistic regression was used to identify factors associated with concomitant hypothyroidism. Concomitant disease as an independent predictor for lab abnormalities and increased healthcare utilization was also assessed using multivariable logistic and negative binomial regression. RESULTS:IRR: 1.89, 95% CI 1.08, 3.32). CONCLUSION/CONCLUSIONS:Patients with both IBD and hypothyroidism have an increased likelihood of other extraintestinal manifestations compared to individuals who have IBD without hypothyroidism. Furthermore, patients with concomitant disease exhibited greater healthcare utilization, specifically, increased rates of RBAI studies. The presence of concomitant hypothyroidism may be associated with a more severe course of IBD.

INTRODUCTION/UNASSIGNED:Cryptogenic multifocal ulcerative stenosing enteritis (CMUSE) is a rare and underrecognized small bowel disorder that often mimics Crohn's disease, leading to delays in diagnosis and misdirected treatment. Given its relapsing nature and resistance to conventional inflammatory bowel disease (IBD) therapies, CMUSE presents significant diagnostic and therapeutic challenges. CASE PRESENTATION/UNASSIGNED:We present the case of a 41-year-old male with chronic anemia, fatigue, weight loss, and intermittent abdominal pain with melena, who remained undiagnosed for 9 years despite extensive evaluations. Imaging and endoscopy failed to identify a definitive cause, and management with TNF inhibitors and IL-12/IL-23 blockade provided only temporary relief. The patient required multiple surgical resections due to recurrent strictures. Pathological examination consistently revealed multifocal jejunal ulceration with stenosis but lacked granulomas, vasculitis, or systemic inflammatory markers, ultimately confirming CMUSE. Given its distinct pathology and treatment resistance, differentiating CMUSE from Crohn's disease is essential. The patient's ongoing management includes upadacitinib, a JAK1 inhibitor, which may help modulate immune pathways contributing to ulcer formation and stricture development. CONCLUSION/UNASSIGNED:This case underscores the need for heightened clinical recognition of CMUSE, particularly in patients with unexplained small bowel strictures and ulceration unresponsive to standard IBD therapies. Genetic testing may aid in distinguishing CMUSE from Crohn's disease, preventing unnecessary immunosuppressive treatments. Further research is necessary to establish effective, targeted therapies and improve outcomes for patients with this rare condition.

INTRODUCTION/UNASSIGNED:Chronic gastrointestinal bleeding in patients with Crohn's disease presents diagnostic challenges. Adult intussusception is rare and typically caused by a pathological lead point, such as a tumor or inflammatory lesion. Lipomas, though benign, can lead to obstruction and bleeding, requiring differentiation from inflammatory causes for appropriate management. CASE PRESENTATION/UNASSIGNED:A 70-year-old male with Crohn's disease and chronic anemia presented with recurrent obscure gastrointestinal bleeding. Initial endoscopy was unremarkable, but capsule endoscopy identified a bleeding jejunal lesion. Double-balloon enteroscopy and imaging confirmed a jejunal lipoma causing intermittent intussusception. Due to persistent anemia, the patient underwent laparoscopic resection, with pathology confirming an ulcerated lipoma. His anemia resolved postoperatively. CONCLUSION/UNASSIGNED:This case underscores the importance of considering structural lesions like lipomas in patients with chronic bleeding and Crohn's disease. A multimodal approach, including advanced imaging and enteroscopy, is crucial for accurate diagnosis and management. Surgical resection remains the preferred treatment for symptomatic small bowel lipomas.

BACKGROUND:As the inflammatory bowel disease (IBD) patient population is aging, the prevalence of polypharmacy is rising. However, data exploring the prevalence, risk factors, and clinical outcomes associated with polypharmacy among older adults with IBD are limited. AIMS/OBJECTIVE:To determine (i) prevalence of polypharmacy (≥5 medications) and potentially inappropriate medication (PIM) utilization in older adults with IBD, (ii) changes in medications over time (iii) predictors of polypharmacy, and (iv) the impact of polypharmacy/PIMs on one-year hospitalization rates. METHODS:We conducted a retrospective single-center study of older adults with IBD from September 1st 2011 to December 31st 2022. Wilcoxon-signed rank and McNemar's tests were used to assess changes in polypharmacy between visits, with ordinal logistic regression and Cox proportional hazards models used to determine risk factors for polypharmacy and time to hospitalization, respectively. RESULTS:Among 512 older adults with IBD, 74.0% experienced polypharmacy at initial visit, with 42.6% receiving at least one PIM. Additionally, severe polypharmacy (≥10 medications) was present among 28.6% individuals at index visit and increased to 38.6% by last visit (p<0.01). Multivariable analysis revealed that age ≥70 years, BMI ≥30.0 kg/m2, prior IBD-related surgery, and the presence of comorbidities were associated with polypharmacy. Moreover, severe polypharmacy (adjHR 1.95, 95%CI 1.29-2.92), as well as PIM use (adjHR 2.16, 95%CI 1.37-3.43) among those with polypharmacy, were significantly associated with all-cause hospitalization within a year of index visit. DISCUSSION/CONCLUSIONS:Severe polypharmacy was initially present in more than 25% of older adults with IBD and increased to 34% within 4 years of index visit. Severe polypharmacy, as well as PIM utilization among those with polypharmacy, were also associated with an increased risk of hospitalization at one-year, highlighting the need for deprescribing efforts in this population.

Juvenile polyposis syndrome lies within the family of hamartomatous polyposis syndromes characterized by polyps that appear benign but harbor an increased risk of colorectal and gastric cancer. This 27-year-old man with severe ulcerative colitis was discovered to have concomitant juvenile polyposis syndrome during diagnostic workup for gastrointestinal bleeding. The implications of this rare association complicate both diagnostic and treatment modalities since both diseases confer an increased risk of cancer.

Spirochete colonization of the gastrointestinal tract is a poorly understood phenomenon presenting with varying signs and symptoms. Due to the lack of a unified approach and its varying presentations, the management decision for intestinal spirochetosis (IS) has always been challenging. While metronidazole is the commonly preferred antimicrobial treatment, it remains unclear if therapeutic intervention is indicated for everyone, especially asymptomatic patients. We present three patients, diagnosed with IS. They presented with varying demographics, clinical presentations, and past medical histories and underwent different clinical managements. Our decisions for treatment not only included presenting symptoms but also factors like history of pre-existing gastrointestinal diseases, age, and immune status.

As the prevalence of older adults with inflammatory bowel disease (IBD) is rising, understanding the unique challenges in both diagnosis and management is becoming increasingly important. Knowledge of phenotypic differences as well as overlapping symptoms with other medical conditions is critical to obtaining a timely diagnosis of IBD in older adults. Although older adults with IBD are at higher risk for adverse events compared with younger adults with IBD, recent data have suggested that ongoing disease activity may be a significant driver of adverse clinical outcomes rather than use of current treatment modalities. Ultimately, earlier and effective treatments can improve outcomes and quality of life for older adults with IBD. However, to help improve medical decision-making, clinicians must move away from the use of chronological age alone and begin to integrate measures of biological age, such as frailty and sarcopenia, into risk stratification tools. This article reviews the management considerations for older adults with IBD and provides the rationale for incorporating measures of biological age into current practice.

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.
