RESUMO
PURPOSE OF REVIEW: This review details the three new agents, including two novel mechanisms of action, approved to treat Crohn's disease in recent years. We review efficacy, safety, prescribing information, and available data on positioning these new therapies. RECENT FINDINGS: Risankizumab and upadacitinib are novel mechanisms of action approved to treat moderate to severe Crohn's disease. Risankizumab targets the cytokine interleukin-23. Upadacitinib is a selective Janus kinase-1 inhibitor approved for use in individuals who have previously failed or are intolerant to an anti-TNF agent. Subcutaneous infliximab provides a novel method of administering maintenance dosing of a longstanding and efficacious therapy. SUMMARY: Risankizumab has shown efficacy in both biologic naïve and biologic experienced populations. The SEQUENCE trial shows superiority of risankizumab over ustekinumab for disease response in patients who have previously failed an anti-tumor necrosis factor agent. Upadacitinib has shown good efficacy in clinical trials even in the setting of a mandated steroid taper during induction. Subcutaneous infliximab maintenance therapy appears noninferior to i.v. infliximab and shows good treatment persistence in real world transitions. Additional data is needed to better understand how to position these therapies.

BACKGROUND: While the pathogenesis of inflammatory bowel disease (IBD) is incompletely understood, disruption of epithelial integrity is suspected to play a prominent role in disease initiation and progression. Currently, there is no convenient way to measure this in vivo. AIMS: Our aim is to determine whether a mucosal integrity (MI) testing device that has been used to measure MI in the esophagus can also be used to measure barrier function in the colon during colonoscopy. METHODS: Mucosal integrity testing was measured in patients with IBD (n = 17) and controls (n = 7) during colonoscopy. During the procedure, an MI catheter was passed down the working channel of the colonoscope and placed along the mucosal wall to measure MI in the rectum, left, transverse, and right colon. In patients with IBD, MI measurements and biopsies were taken in areas which appeared inflamed when present. We then determined if there was a significant difference in MI between patients with IBD and controls. RESULTS: MI was significantly higher in the rectum of patients with IBD (CD and UC combined) versus control colons [767 (618-991) vs. 531 (418-604) ohms, P < 0.01]. There were no significant differences in MI among patients with IBD versus controls in the right, transverse, or left colon. Within the IBD group, there were no significant differences in MI between inflamed versus non-inflamed rectums. There was no correlation between quality of life scores or endoscopic severity with MI, though this study was likely underpowered to detect these differences. CONCLUSION: Rectal MI is significantly higher in patients with IBD versus controls. Future studies are needed to determine how this information can be used clinically.

BACKGROUND: Vedolizumab is a monoclonal antibody used to treat inflammatory bowel disease (IBD). There is little known about the safety and comparative efficacy of this agent in the elderly population. AIMS: Here, we present data on the safety and comparative efficacy of vedolizumab versus tumor necrosis factor α antagonists (anti-TNF) in elderly patients with IBD. METHODS: This retrospective cohort study included IBD patients started on vedolizumab or anti-TNF at age 60 or older at a single tertiary IBD center. Safety was evaluated by assessing for the development of serious infection. The comparative needs for IBD-related surgery, IBD-related hospitalization, and drug discontinuation for any reason were obtained. Efficacy was assessed by comparing changes in endoscopic, histologic, and patient-report outcomes. RESULTS: 212 cases were identified-108 patients treated with vedolizumab and 104 patients treated with anti-TNF. There were no significant differences between cohorts in serious infection, surgical intervention, or IBD-hospitalization-free survival (p = NS). Drug discontinuation survival was different between anti-TNF and vedolizumab (p = 0.02) with more patients remaining on vedolizumab at the time of last follow-up (51.9% vs. 25.9%). Endoscopic remission and response rates were higher in the vedolizumab versus anti-TNF group (65.7% vs. 45.2%, p = 0.02; 80.0% vs. 59.3%, p < 0.001). CONCLUSIONS: In a cohort of IBD patients over age 60, vedolizumab showed no statistically significant differences in infection, hospitalization, or surgical intervention-free survival as compared to anti-TNF. Vedolizumab was discontinued less frequently than anti-TNF. Patients on vedolizumab had higher rates of endoscopic remission and response.

BACKGROUND & AIMS: Countries endemic for parasitic infestations have a lower incidence of Crohn's disease (CD) than nonendemic countries, and there have been anecdotal reports of the beneficial effects of helminths in CD patients. Tuft cells in the small intestine sense and direct the immune response against eukaryotic parasites. We investigated the activities of tuft cells in patients with CD and mouse models of intestinal inflammation. METHODS: We used microscopy to quantify tuft cells in intestinal specimens from patients with ileal CD (n = 19), healthy individuals (n = 14), and TNFΔARE/+ mice, which develop Crohn's-like ileitis. We performed single-cell RNA sequencing, mass spectrometry, and microbiome profiling of intestinal tissues from wild-type and Atoh1-knockout mice, which have expansion of tuft cells, to study interactions between microbes and tuft cell populations. We assessed microbe dependence of tuft cell populations using microbiome depletion, organoids, and microbe transplant experiments. We used multiplex imaging and cytokine assays to assess alterations in inflammatory response following expansion of tuft cells with succinate administration in TNFΔARE/+ and anti-CD3E CD mouse models. RESULTS: Inflamed ileal tissues from patients and mice had reduced numbers of tuft cells, compared with healthy individuals or wild-type mice. Expansion of tuft cells was associated with increased expression of genes that regulate the tricarboxylic acid cycle, which resulted from microbe production of the metabolite succinate. Experiments in which we manipulated the intestinal microbiota of mice revealed the existence of an ATOH1-independent population of tuft cells that was sensitive to metabolites produced by microbes. Administration of succinate to mice expanded tuft cells and reduced intestinal inflammation in TNFΔARE/+ mice and anti-CD3E-treated mice, increased GATA3+ cells and type 2 cytokines (IL22, IL25, IL13), and decreased RORGT+ cells and type 17 cytokines (IL23) in a tuft cell-dependent manner. CONCLUSIONS: We found that tuft cell expansion reduced chronic intestinal inflammation in mice. Strategies to expand tuft cells might be developed for treatment of CD.

Introduction: Varenicline doubles cessation over nicotine replacement therapy (NRT) patch for "normal," but not "slow," nicotine metabolizers, as assessed by the nicotine metabolite ratio (NMR). Metabolism-informed care (MIC) could improve outcomes by matching normal metabolizers with non-nicotine medication (e.g., varenicline) and slow metabolizers with NRT patch. Methods: We conducted a feasibility randomized controlled trial of MIC versus guideline based care (GBC) among 81 outpatient adult daily smokers with medical comorbidity. Participants reported perceptions of MIC, underwent blood draw for NMR, and received expert cessation counseling. For MIC participants, medication selection was informed by NMR result (normal (≥0.31) vs. slow (< 0.31)). The primary outcome was MIC feasibility, reflected by attitudes toward MIC and by match rates between NMR and medication. Secondary endpoints (cessation confidence, medication use, smoking status) were assessed over 6 months to inform future studies. Results: Participants were median age 53 years, 46% female, 28% black, and ~90% endorsed MIC. Despite high varenicline prescription rates (~60%) in both arms, NMR-medication matching was higher in MIC (84%) versus GBC (58%) participants (p=0.02); unadjusted odds ratio (OR) 3.67, 95% confidence interval [1.33, 11.00; p-value=0.02]. Secondary endpoints were similar at 1, 3, and 6 months. Conclusions: MIC, an NMR-based precision approach to smoking cessation, was acceptable to 90% of smokers and improved NMR-medication match rates more than 3-fold compared to GBC, even with generally high use of varenicline. These data support the feasibility of MIC, which could maximize efficacy of smoking cessation medication while minimizing side effects and cost. Implications: Among treatment-seeking daily smokers with medical comorbidity, most viewed metabolism-informed care (MIC), guided by the nicotine metabolism ratio (NMR), favorably, and were willing to accept MIC-guided medication. Compared to GBC participants (58%), more MIC participants (84%) were prescribed NMR-matched medication (i.e., normal metabolizers received varenicline; slow metabolizers received NRT patch). MIC increased the odds of optimized matching between NMR and medication more than 3-fold over GBC. Because the number needed to treat (NNT) to help one normal metabolizer quit smoking is only 4.9 for varenicline versus 26 for patch, broad implementation of MIC will improve drug efficacy in normal metabolizers as well as minimize side effects in slow metabolizers.

BACKGROUND & AIMS: Patients with inflammatory bowel diseases (IBDs) have increased risk for venous thromboembolism (VTE); those who require hospitalization have particularly high risk. Few hospitalized patients with IBD receive thromboprophylaxis. We analyzed the frequency of VTE after IBD-related hospitalization, risk factors for post-hospitalization VTE, and the efficacy of prophylaxis in preventing post-hospitalization VTE. METHODS: In a retrospective study, we analyzed data from a multi-institutional cohort of patients with Crohn's disease or ulcerative colitis and at least 1 IBD-related hospitalization. Our primary outcome was a VTE event. All patients contributed person-time from the date of the index hospitalization to development of VTE, subsequent hospitalization, or end of follow-up. Our main predictor variable was pharmacologic thromboprophylaxis. Cox proportional hazard models adjusting for potential confounders were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: From a cohort of 2788 patients with at least 1 IBD-related hospitalization, 62 patients developed VTE after discharge (2%). Incidences of VTE at 30, 60, 90, and 180 days after the index hospitalization were 3.7/1000, 4.1/1000, 5.4/1000, and 9.4/1000 person-days, respectively. Pharmacologic thromboprophylaxis during the index hospital stay was associated with a significantly lower risk of post-hospitalization VTE (HR, 0.46; 95% CI, 0.22-0.97). Increased numbers of comorbidities (HR, 1.30; 95% CI, 1.16-1.47) and need for corticosteroids before hospitalization (HR, 1.71; 95% CI, 1.02-2.87) were also independently associated with risk of VTE. Length of hospitalization or surgery during index hospitalization was not associated with post-hospitalization VTE. CONCLUSIONS: Pharmacologic thromboprophylaxis during IBD-related hospitalization is associated with reduced risk of post-hospitalization VTE.

Background: Longitudinal research reveals a unidirectional relationship between a nonsomatic symptom of depression, a negative view of the self, and later reported Crohn's disease (CD) activity. We evaluated whether health behaviors mediated this association using a longitudinal design. Methods: We studied 3304 adult volunteers with a self-reported diagnosis of CD who completed a baseline survey that included demographics, CD activity, a symptom-specific index of depression, and measures of physical activity, smoking, and sleep quality. Crohn's disease status and the cognitive index of depression were also measured 6 and 12 months after the baseline evaluation. We specified single-mediator and multiple-mediator models to elucidate the depression-disease activity relationship. Results: Among 2395 females and 909 males, we found a significant mediation effect for activity level (P < .001) after adjusting for age, sex, and body mass index. There was no evidence that sleep quality and smoking are significant single mediators. When we considered multiple mediation models, smoking and less activity partially mediate the depression-CD association. Conclusions: Smoking and lower levels of physical activity are potential mediators of the unidirectional association between a nonsomatic symptom of depression-a negative view of the self-and patient-reported CD activity. Evaluating and treating specific symptoms of depression may reduce the frequency of CD exacerbations.
RESUMO
Background: When it comes to readiness to transition to an adult subspecialty clinic, perspectives between patients with inflammatory bowel disease (IBD) and their caregivers may differ and influence the ability to successfully transition. Patients with IBD have been shown to suffer from poor transfers of care. There is a need to more efficiently and accurately assess transition readiness to improve the transfer process. Methods: Patients transferring to an adult subspecialty clinic and their caregivers were each administered the Transition Readiness Assessment Questionnaire and IBD Self-Efficacy Scale-Adolescent. Differences between patient and caregiver responses and agreement among each dyad were tested. Results: There were 29 dyads of patients and caregivers who enrolled. There was no difference between patient and caregiver total scores. The average level of agreement between patients and caregivers was 78%. There was no association between patient response and their age, gender, ethnicity, age at time of transfer, age at diagnosis, or number of emergency room visits in the prior year. Conclusions: Patient-reported readiness to transition to adult care was confirmed by their caregivers using validated readiness assessment tools. As transition clinics must focus on high-yield interventions, a readiness survey of young adult patients without a survey of their caregivers may be adequate. However, as experts in each patient's journey, caregivers may be utilized when setting goals and priorities for a transition readiness program. The surveys used in this study can be used broadly to aid subspecialty clinics that are trying to improve the transition process.
RESUMO
Crohn's disease (CD) is a complex chronic inflammatory disorder with both gastrointestinal and extra-intestinal manifestations associated immune dysregulation. Analyzing 202,359 cells from 170 specimens across 83 patients, we identify a distinct epithelial cell type in both terminal ileum and ascending colon (hereon as 'LND') with high expression of LCN2, NOS2, and DUOX2 and genes related to antimicrobial response and immunoregulation. LND cells, confirmed by in-situ RNA and protein imaging, are rare in non-IBD controls but expand in active CD, and actively interact with immune cells and specifically express IBD/CD susceptibility genes, suggesting a possible function in CD immunopathogenesis. Furthermore, we discover early and late LND subpopulations with different origins and developmental potential. A higher ratio of late-to-early LND cells correlates with better response to anti-TNF treatment. Our findings thus suggest a potential pathogenic role for LND cells in both Crohn's ileitis and colitis.

INTRODUCTION: The need to rapidly implement telehealth at large scale during the COVID-19 pandemic led to many patients using telehealth for the first time. We assessed the effect of structured pre-visit preparatory telephone calls on success of telehealth visits and examined risk factors for unsuccessful visits. METHODS: A retrospective cohort study was carried out of 45,803 adult patients scheduled for a total of 64,447 telehealth appointments between March and July 2020 at an academic medical center. A subset of patients received a structured pre-visit phone call. Demographic factors and inclusion of a pre-visit call were analysed by logistic regression. Primary outcomes were non-completion of any visit and completion of phone-only versus audio-visual telehealth visits. RESULTS: A pre-visit telephone call to a subset of patients significantly increased the likelihood of a successful telehealth visit (OR 0.54; 95% CI: 0.48-0.60). Patients aged 18-30 years, those with non-commercial insurance or those of Black race were more likely to have incomplete visits. Compared to age 18-30, increasing age increased likelihood of a failed video visit: 31-50 years (OR 1.31; 95% CI: 1.13-1.51), 51-70 years (OR 2.98; 2.60-3.42) and >70 years (OR 4.16; 3.58-4.82). Those with non-commercial insurance and those of Black race (OR 1.8; 95% CI 1.67-1.92) were more likely to have a failed video visit. DISCUSSION: A structured pre-call to patients improved the likelihood of a successful video visit during widespread adoption of telehealth. Structured pre-calls to patients may be an important tool to help reduce gaps in utilization among groups.

Background and Aims: This study aimed to evaluate adherence to subcutaneous biologic therapy and impact of nonadherence including risk factors and outcomes in academic centers with integrated specialty pharmacies for patients with inflammatory bowel disease (IBD). Methods: This was a multicenter, retrospective cohort analysis of patients aged ≥18 years receiving care in 3 tertiary care outpatient IBD clinics with integrated specialty pharmacies. Subjects were prescribed injectable anti-TNF therapy (adalimumab, certolizumab, golimumab) or anti-IL 12/23 therapy (ustekinumab) with at least 3 consecutive prescription claims. The primary outcomes were medication possession ratio (MPR), percent achieving optimal adherence (MPR > 0.86); in addition, we sought to verify a prior risk factor model including smoking status, narcotic use, psychiatric history, and prior biologic use. Secondary outcomes included emergency department visits (ED) and IBD-related hospitalizations. Statistical analysis was performed using Wilcox rank sum test, Pearson's Chi-squared test, and logistic regression model as an unordered, factor variable to flexibly estimate the probabilities of adherence. Results: Six hundred eight subjects were included. Overall median MPR was 0.95 (interquartile range 0.47, 1) and adherence was 68%-70%. When the number of risk factors for nonadherence increased, the likelihood of nonadherence increased (P < .05). In unadjusted and adjusted analysis, nonadherence increased the likelihood of ED visits [rate ratio 1.45 (95% confidence interval 1.05, 1.97)] and hospitalizations [rate ratio 1.60 (95% confidence interval 1.16, 2.10)]. Conclusion: Academic centers with integrated pharmacies had high adherence. Prior risk factors for nonadherence remained significant in this multicenter model. Nonadherence was associated with higher likelihood of hospitalizations and ED visits.
RESUMO
Crohn's disease (CD) is a complex chronic inflammatory disorder that may affect any part of gastrointestinal tract with extra-intestinal manifestations and associated immune dysregulation. To characterize heterogeneity in CD, we profiled single-cell transcriptomics of 170 samples from 65 CD patients and 18 non-inflammatory bowel disease (IBD) controls in both the terminal ileum (TI) and ascending colon (AC). Analysis of 202,359 cells identified a novel epithelial cell type in both TI and AC, featuring high expression of LCN2, NOS2, and DUOX2, and thus is named LND. LND cells, confirmed by high-resolution in-situ RNA imaging, were rarely found in non-IBD controls, but expanded significantly in active CD. Compared to other epithelial cells, genes defining LND cells were enriched in antimicrobial response and immunoregulation. Moreover, multiplexed protein imaging demonstrated that LND cell abundance was associated with immune infiltration. Cross-talk between LND and immune cells was explored by ligand-receptor interactions and further evidenced by their spatial colocalization. LND cells showed significant enrichment of expression specificity of IBD/CD susceptibility genes, revealing its role in immunopathogenesis of CD. Investigating lineage relationships of epithelial cells detected two LND cell subpopulations with different origins and developmental potential, early and late LND. The ratio of the late to early LND cells was related to anti-TNF response. These findings emphasize the pathogenic role of the specialized LND cell type in both Crohn's ileitis and Crohn's colitis and identify novel biomarkers associated with disease activity and treatment response.
RESUMO
Background: Natural language processing models such as ChatGPT can generate text-based content and are poised to become a major information source in medicine and beyond. The accuracy and completeness of ChatGPT for medical queries is not known. Methods: Thirty-three physicians across 17 specialties generated 284 medical questions that they subjectively classified as easy, medium, or hard with either binary (yes/no) or descriptive answers. The physicians then graded ChatGPT-generated answers to these questions for accuracy (6-point Likert scale; range 1 - completely incorrect to 6 - completely correct) and completeness (3-point Likert scale; range 1 - incomplete to 3 - complete plus additional context). Scores were summarized with descriptive statistics and compared using Mann-Whitney U or Kruskal-Wallis testing. Results: Across all questions (n=284), median accuracy score was 5.5 (between almost completely and completely correct) with mean score of 4.8 (between mostly and almost completely correct). Median completeness score was 3 (complete and comprehensive) with mean score of 2.5. For questions rated easy, medium, and hard, median accuracy scores were 6, 5.5, and 5 (mean 5.0, 4.7, and 4.6; p=0.05). Accuracy scores for binary and descriptive questions were similar (median 6 vs. 5; mean 4.9 vs. 4.7; p=0.07). Of 36 questions with scores of 1-2, 34 were re-queried/re-graded 8-17 days later with substantial improvement (median 2 vs. 4; p<0.01). Conclusions: ChatGPT generated largely accurate information to diverse medical queries as judged by academic physician specialists although with important limitations. Further research and model development are needed to correct inaccuracies and for validation.
RESUMO
Importance: Natural language processing tools, such as ChatGPT (generative pretrained transformer, hereafter referred to as chatbot), have the potential to radically enhance the accessibility of medical information for health professionals and patients. Assessing the safety and efficacy of these tools in answering physician-generated questions is critical to determining their suitability in clinical settings, facilitating complex decision-making, and optimizing health care efficiency. Objective: To assess the accuracy and comprehensiveness of chatbot-generated responses to physician-developed medical queries, highlighting the reliability and limitations of artificial intelligence-generated medical information. Design, Setting, and Participants: Thirty-three physicians across 17 specialties generated 284 medical questions that they subjectively classified as easy, medium, or hard with either binary (yes or no) or descriptive answers. The physicians then graded the chatbot-generated answers to these questions for accuracy (6-point Likert scale with 1 being completely incorrect and 6 being completely correct) and completeness (3-point Likert scale, with 1 being incomplete and 3 being complete plus additional context). Scores were summarized with descriptive statistics and compared using the Mann-Whitney U test or the Kruskal-Wallis test. The study (including data analysis) was conducted from January to May 2023. Main Outcomes and Measures: Accuracy, completeness, and consistency over time and between 2 different versions (GPT-3.5 and GPT-4) of chatbot-generated medical responses. Results: Across all questions (n = 284) generated by 33 physicians (31 faculty members and 2 recent graduates from residency or fellowship programs) across 17 specialties, the median accuracy score was 5.5 (IQR, 4.0-6.0) (between almost completely and complete correct) with a mean (SD) score of 4.8 (1.6) (between mostly and almost completely correct). The median completeness score was 3.0 (IQR, 2.0-3.0) (complete and comprehensive) with a mean (SD) score of 2.5 (0.7). For questions rated easy, medium, and hard, the median accuracy scores were 6.0 (IQR, 5.0-6.0), 5.5 (IQR, 5.0-6.0), and 5.0 (IQR, 4.0-6.0), respectively (mean [SD] scores were 5.0 [1.5], 4.7 [1.7], and 4.6 [1.6], respectively; P = .05). Accuracy scores for binary and descriptive questions were similar (median score, 6.0 [IQR, 4.0-6.0] vs 5.0 [IQR, 3.4-6.0]; mean [SD] score, 4.9 [1.6] vs 4.7 [1.6]; P = .07). Of 36 questions with scores of 1.0 to 2.0, 34 were requeried or regraded 8 to 17 days later with substantial improvement (median score 2.0 [IQR, 1.0-3.0] vs 4.0 [IQR, 2.0-5.3]; P < .01). A subset of questions, regardless of initial scores (version 3.5), were regenerated and rescored using version 4 with improvement (mean accuracy [SD] score, 5.2 [1.5] vs 5.7 [0.8]; median score, 6.0 [IQR, 5.0-6.0] for original and 6.0 [IQR, 6.0-6.0] for rescored; P = .002). Conclusions and Relevance: In this cross-sectional study, chatbot generated largely accurate information to diverse medical queries as judged by academic physician specialists with improvement over time, although it had important limitations. Further research and model development are needed to correct inaccuracies and for validation.

Background: A Functional Medicine program was developed at an inflammatory bowel disease (IBD) center with the goal of integrating strategies to address modifiable lifestyle factors and to complete a 6-week elimination diet under the direction of a trained Functional Medicine dietitian and Functional Medicine providers. Methods: From January 2019 to November 2019, patients with controlled, but persistent, symptoms from IBD were offered enrollment. Each of the 5 visits incorporated an educational session focused on nutrition followed by a session focusing on modifiable lifestyle factors. The patients were placed on a supervised 6-week elimination diet. At each visit, patients completed the SIBDQ (Short Inflammatory Bowel Disease Questionnaire), FSS (Fatigue Severity Scale), PSQI (The Pittsburgh Sleep Quality Index), and MSQ (Medical Symptoms Questionnaire). Statistical analysis was performed using the Wilcoxon matched pairs signed-rank test. Results: Nineteen patients enrolled (2 men: 1 ulcerative colitis [UC], 1 Crohn's disease [CD]; 17 women: 3 UC, 14 CD). 15 patients completed all modules. There was improvement in all patient-reported outcomes (PROs) (FSS, P < .001; PSQI, P < .001; SIBDQ, P < .001; MSQ, P < .001). Every patient who completed the last session demonstrated weight loss. Conclusions: The psychoemotional roots to immune disease states, particularly IBD, are complicated and often not addressed in traditional care. We are just beginning to understand the impact of nutrition, sleep, stress, movement, and relationships on IBD. In this cohort, utilizing Functional Medicine as an adjunct to traditional care resulted in improvement in all PROs.
RESUMO
BACKGROUND: This study evaluated synchronous audiovisual telehealth and audio-only visits for patients with inflammatory bowel disease (IBD) to determine frequency of successful telehealth visits and determine what factors increase the likelihood of completion. METHODS: Data were collected from March to July 2020 in a tertiary care adult IBD clinic that was transitioned to a fully telehealth model. A protocol for telehealth was implemented. A retrospective analysis was performed using electronic medical record (EMR) data. All patients were scheduled for video telehealth. If this failed, providers attempted to conduct the visit as audio only. RESULTS: Between March and July 2020, 2571 telehealth visits were scheduled for adult patients with IBD. Of these, 2498 (99%) were successfully completed by video or phone. Sixty percent were female, and the median age was 41 years. Eighty six percent of the population was white, 8% black, 2% other, and 4% were missing. Seventy-five percent had commercial insurance, 15% had Medicare, 5% had Medicaid, and 5% had other insurance. No significant factors were found for an attempted but completely failed visit. Using a multivariate logistic regression model, increasing age (odds ratio, 1.80; 95% CI, 1.55-2.08; Pâ <â 0.05), noncommercial insurance status (odds ratio, 1.89; 95% CI, 1.61-2.21; Pâ <â 0.05), and black race (odds ratio, 2.07; 95% CI, 1.38-3.08; P < 0.05) increased the likelihood of a video encounter failure. CONCLUSIONS: There is a high success rate for telehealth within an IBD population with defined clinic protocols. Certain patient characteristics such as age, race, and health insurance type increase the risk of failure of a video visit.

BACKGROUND: Prior research demonstrates Crohn's disease patients often do well in pregnancy; however, less is known about the risk of flare in the postpartum period. METHODS: A retrospective chart review was conducted at a tertiary care inflammatory bowel disease center. All pregnant women with Crohn's disease who were followed in the postpartum period, defined as 6 months after delivery, were included. Statistical analysis included χâ2 analysis, Wilcoxon rank sum test, and logistic regression analysis. The primary outcome of interest was rate of flare in the postpartum period. RESULTS: There were 105 patients included in the study, with a majority (68%) on biologic medication during pregnancy. Thirty-one patients (30%) had a postpartum flare at a median of 9 weeks (range 2-24 weeks). Twenty-five patients (81%) had their postpartum flare managed in the outpatient setting with medications (only 4 of these patients required prednisone). 6 of 31 patients (19%) were hospitalized at a median of 4 weeks (range 2-26 weeks) after delivery, requiring intravenous corticosteroids or surgery. In multivariable regression, there was no significant increase in risk of postpartum flare with increasing maternal age, flare during pregnancy, or steroid or biologic use during pregnancy. Smoking during pregnancy increased risk of postpartum flare (odds ratio, 16.2 [1.72-152.94], Pâ <â 0.05). CONCLUSION: In a cohort of Crohn's disease patients, 30% experienced a postpartum flare despite being on medical therapy, but most were able to be managed in the outpatient setting.

BACKGROUND: Clinical and molecular subcategories of inflammatory bowel disease (IBD) are needed to discover mechanisms of disease and predictors of response and disease relapse. We aimed to develop a study of a prospective adult research cohort with IBD (SPARC IBD) including longitudinal clinical and patient-reported data and biosamples. METHODS: We established a cohort of adults with IBD from a geographically diverse sample of patients across the United States with standardized data and biosample collection methods and sample processing techniques. At enrollment and at time of lower endoscopy, patient-reported outcomes (PRO), clinical data, and endoscopy scoring indices are captured. Patient-reported outcomes are collected quarterly. The quality of clinical data entry after the first year of the study was assessed. RESULTS: Through January 2020, 3029 patients were enrolled in SPARC, of whom 66.1% have Crohn's disease (CD), 32.2% have ulcerative colitis (UC), and 1.7% have IBD-unclassified. Among patients enrolled, 990 underwent colonoscopy. Remission rates were 63.9% in the CD group and 80.6% in the UC group. In the quality study of the cohort, there was 96% agreement on year of diagnosis and 97% agreement on IBD subtype. There was 91% overall agreement describing UC extent as left-sided vs extensive or pancolitis. The overall agreement for CD behavior was 83%. CONCLUSION: The SPARC IBD is an ongoing large prospective cohort with longitudinal standardized collection of clinical data, biosamples, and PROs representing a unique resource aimed to drive discovery of clinical and molecular markers that will meet the needs of precision medicine in IBD.
