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.

Comparative Safety of Biologic Agents in Patients With Inflammatory Bowel Disease With Active or Recent Malignancy: A Multi-Center Cohort Study

Holmer, Ariela K; Luo, Jiyu; Russ, Kirk B; Park, Sarah; Yang, Jeong Yun; Ertem, Furkan; Dueker, Jeffrey; Nguyen, Vu; Hong, Simon; Zenger, Cameron; Axelrad, Jordan E; Sofia, Anthony; Petrov, Jessica C; Al-Bawardy, Badr; Fudman, David I; Llano, Ernesto; Dailey, Joseph; Jangi, Sushrut; Khakoo, Nidah; Damas, Oriana M; Barnes, Edward L; Scott, Frank I; Ungaro, Ryan C; Singh, Siddharth
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.

Risk factors for incomplete telehealth appointments among patients with inflammatory bowel disease

Stone, Katherine L; Kulekofsky, Emma; Hudesman, David; Kozloff, Samuel; Remzi, Feza; Axelrad, Jordan E; Katz, Seymour; Hong, Simon J; Holmer, Ariela; McAdams-DeMarco, Mara A; Segev, Dorry L; Dodson, John; Shaukat, Aasma; Faye, Adam S
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.

Ustekinumab and Vedolizumab Are Not Associated With Subsequent Cancer in IBD Patients with Prior Malignancy

Hong, Simon J; Zenger, Cameron; Pecoriello, Jillian; Pang, Alice; Vallely, Margaret; Hudesman, David P; Chang, Shannon; Axelrad, Jordan E
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.

Level and Change of CRP Are Associated With 30-Day Risk of Colectomy in Patients Hospitalized With Acute Severe Ulcerative Colitis Receiving Infliximab [Meeting Abstract]

Kahan, T F; Hong, S; Holmer, A K; Axelrad, J; Faye, A
Introduction: Infliximab (IFX) has been efficacious in reducing colectomy rates among patients with moderate-to severe ulcerative colitis, but predictors of colectomy within 30 days of IFX among patients with acute severe ulcerative colitis (ASUC) are less established.
Method(s): We performed a single-center retrospective analysis of patients who received at least one dose of IFX while admitted between 2011-2022. We assessed demographic, clinical and laboratory predictors of colectomy within 30 days of first IFX dose. Multivariable and time-to-event analysis using Kaplan-Meier with log-rank statistics were used to assess risk factors for colectomy within 30 days.
Result(s): A majority of the 172 patients hospitalized with ASUC who received IFX received 10 mg/kg (87.79%). Overall, 22/172 patients (12.79%) underwent colectomy within 30 days of first IFX dose. On univariable analysis, age, sex, race, ethnicity, BMI and smoking status were not associated with risk of colectomy. Higher initial CRP was significantly associated with 30-day risk of colectomy (106.17 vs. 65.10 mg/dL among patients who did not undergo colectomy; p< 0.01), as was a decrease of CRP <=50% prior to discharge (p< 0.01). Lower initial albumin [< 3 (36.36%), 3.0-3.5 (40.91%), >3.5 g/dL (22.73%)] was associated with our primary outcome (p=0.046), as was a higher number of bowel movements in a 24-hour period prior to discharge (5.6 vs. 3.9 among patients who did not undergo colectomy; p=0.0256). On multivariable analysis, higher initial CRP (aOR 1.01, 95% CI 1.00 - 1.02), <=50% change in CRP after first dose of IFX (aOR 9.00, 95% CI 2.43 - 33.29) and higher number of bowel movements in a 24-hour period prior to discharge (aOR 1.24, 95% CI 1.01- 1.52) remained significantly associated with risk of colectomy when adjusting for relevant covariables (Table). On Kaplan-Meier analysis, initial CRP >100 mg/ dL, albumin < 3 g/dL and change in CRP <=50% prior to discharge were significantly associated with decreased time to colectomy (Figure).
Conclusion(s): Among patients with ASUC, higher CRP, decrease of CRP <=50% and higher number of bowel movements prior to discharge were associated with increased risk of colectomy within 30-days of receiving IFX. Initial CRP >100 mg/dL, albumin < 3 g/dL and decrease of <=50% in CRP prior to discharge were associated with decreased time to colectomy. These results can identify patients at highest risk and impact clinical decision-making regarding need for and timing of colectomy in patients with ASUC receiving IFX. (Table Presented)

Impact of Concomitant Hypothyroid Disease and Inflammatory Bowel Disease [Meeting Abstract]

Ahsan, M; Udaikumar, J; Hong, S; Faye, A; Katz, S; Axelrad, J
Introduction: Inflammatory bowel disease (IBD), comprised of Ulcerative Colitis (UC) and Crohn's Disease (CD), is caused by a combination of environmental factors, immune dysregulation, and genetic susceptibility. Other immune-mediated phenomena, like hypothyroidism, have also been observed in this population. Thus, we sought to explore clinical characteristics and outcomes among IBD patients with hypothyroidism compared to IBD patients without hypothyroidism.
Method(s): In a retrospective chart review from a large, tertiary, academic medical center, baseline demographics and clinical data were extracted for patients diagnosed with either UC or CD and having at least one thyroid stimulating hormone (TSH) measurement from prior to 2016. Based on the presence of a documented hypothyroidism ICD-10 code, patients were then divided into two groups, those with IBD alone and those with both IBD and hypothyroidism, as described in Figure. Individual charts were then further examined for disease characteristics, biomarkers, healthcare utilization, medication use, and other comorbidities from 2016 to 2022. Demographic and clinical variables were then compared between the two groups, as seen in Table.
Result(s): We identified 166 adult IBD patients (CD 53%, UC 47%). The mean age was 62.9 years. Among these patients, 116 patients (69.9%) had IBD and hypothyroidism. The most common causes of hypothyroidism were Hashimoto, subclinical, and acquired hypothyroidism. No differences were noted in race, smoking status, or BMI. IBD disease location, behavior, and prevalence of extra-intestinal manifestations did not significantly differ between the two study groups. Both groups had similar number of colonoscopies, hospitalizations, as well as comparable medication use (SSRI/SNRI, steroids, 5-ASA, immunomodulators, biologics). However, patients with IBD and hypothyroidism had higher rates of anemia (p=0.03), hypoalbuminemia (p=0.007), and CRP elevations (p=0.002). Furthermore, patients with both IBD and hypothyroidism had a greater median number of emergency department visits (p=0.039) and axial radiography (p=0.002).
Conclusion(s): IBD patients with hypothyroidism experience a more severe disease course with higher biomarkers of inflammation and healthcare utilization than those without hypothyroidism despite similar IBD phenotype and therapy exposures. This highlights a potential subgroup of IBD patients who may be at risk for increased disease severity and associated poor outcomes. (Table Presented)

IBD 101: Three-Year Follow-Up of a Primer for First-Year GI Fellows [Meeting Abstract]

Hong, S; Kane, S; Hudesman, D; Rubin, D T; Malter, L
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.

Older Adults Are at Higher Risk for Developing Anti-TNF Antibodies [Meeting Abstract]

Faye, A; Hong, S; Axelrad, J; Katz, S; Hudesman, D; Dervieux, T
Introduction: As the inflammatory bowel disease (IBD) patient population ages, there will be an increasing number of individuals requiring advanced therapies. Although older age is thought to be associated with immunosenescence, there are data suggesting that older adults may be at higher risk for antibody development as the result of biologic use.
Method(s): Using a large commercial laboratory database (Prometheus Laboratories), we extracted infliximab (IFX) dosing as well as antibody to infliximab (ATI) levels for all individuals using this assay from 2015-2021. Our primary outcome was the presence of ATI (titer >3.1 U/mL). Frequencies were recorded as categorical variables with chi-square analysis used, and multivariable logistic regression was employed to assess the impact of IFX dose, age (< 60 years-old v. >=60 years-old), and IBD subtype on the development of ATI.
Result(s): Overall, there were 22,197 unique specimens, with 3,028 (13.6%) having ATI. When stratified by age, individuals >=60 years-old developed ATI 18.1% (473/2,612) of the time as compared to 15.0% (2,555/17,030) for individuals < 60 years of age (p< 0.01, Figure). Among all individuals with IFX dose < 10mg q8 weeks, older adults (>=60 years of age) were more likely to develop ATI as compared to younger adults (22.8% vs. 16.2%, respectively, p< 0.01); however, when IFX dose was >=10mg/kg q8 weeks, age >= 60 years-old was no longer significantly associated with the development of ATI (9.9% if < 60 years-old vs. 10.6% if >=60 years-old) on univariable analysis. Overall, older adults were less likely to receive IFX doses >=10mg/kg q8 weeks (38.4% in older adults vs. 49.7% in younger adults; p< 0.01). On multivariable analysis, age >=60 years-old (adjOR 1.35, 95%CI 1.20-1.51), IFX dose >= 10mg/kg q8 weeks (adjOR 0.53, 95%CI 0.49-0.57) and having ulcerative colitis as compared to Crohn's disease (adjOR 1.44, 95%CI 1.33-1.57) were independently associated with the development of ATI.
Conclusion(s): Older adults with IBD develop ATI more frequently than younger adults when adjusting for IFX dose and IBD subtype. However, when IFX dose >=10mg/kg q8 weeks, ATI was significantly less likely to develop among older adults, and occurred in a similar proportion of younger individuals. Further education is needed, highlighting that older adults with IBD are more likely to develop ATI as compared to younger adults, particularly when using lower doses of IFX, and that higher doses may decrease this likelihood.

Gastroenterology Fellowship Virtual Interviews: Applicant and Faculty Perceptions on Virtual Interview Advantages and Barriers [Meeting Abstract]

Khoudari, G; Eltelbany, A; Salem, G; Hakim, S; Narayanan, S; Abegunde, A T; Mahmood, S; Hong, S; Khan, F; Bhurwal, A; Meriwether, M; Haddad, N; Alishahi, Y; Ghali, M P; Tierney, W; Sifuentes, H; DuPont, A W; Vega, K J; Regueiro, M; Mattar, M C
Introduction: During the COVID-19 pandemic, virtual interviews for resident and fellowship applicants became the standard. However, studies evaluating the experience of virtual interviews format are lacking. Accordingly, we sought to survey both gastroenterology fellowship applicants and interviewing faculty members about their experiences with the virtual interview process.
Method(s): Interviewees and faculty at 13 different gastroenterology fellowship programs at academic medical centers across the United States completed a post-interview survey. The online survey was conducted during the 2020 ERAS fellowship interview season via Google Forms. The survey responses were anonymously collected and reported.
Result(s): A total of 177 gastroenterology fellowship applicants and 83 faculty members completed the electronic surveys. Most participants reported a positive experience with 91% and 84% of applicants and faculty respectively, scoring at least 4 points on a 5-point scale. Eighty-8 percent and 85% of applicants and faculty respectively, reported that they had enough insight about the applicant or the fellowship program during the interview. Over 67% of applicants reported cost-savings of greater than $1,000 per interview. Thirty-6 percent of applicants reported that they missed the personal interaction with the current gastroenterology fellows in the respective programs and the experience of physically touring the facility. Twenty-7 percent and 25% of applicants and faculty experienced technical difficulties during the interview process, respectively. Thirty-one percent and 22% of applicants and faculty would like for the virtual interviews to be the standard of future fellowship interviews, while 35% and 42% of applicants and faculty would consider it in the future, respectively. Figure 1 shows the ranking process for both applicants and faculty.
Conclusion(s): Virtual interviews were perceived as effective and cost-saving by both gastroenterology fellowship applicants and faculty members. The virtual experience was widely accepted by most applicants and faculty, with high potential to become the standard of fellowship interview process in the future. However, a substantial portion experienced technical difficulty. Further improvements in technology are needed to optimize the process and increase the acceptance of the virtual interview experience.
