Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract that is associated with malnutrition. Malnutrition is associated with poor clinical outcomes in patients with IBD and therefore early identification of those at risk for malnutrition is crucial. We aimed to evaluate how frequently nutrition screening occurs in a large, tertiary care outpatient IBD center and to initiate an intervention to improve malnutrition screening for patients with IBD.We used a traditional plan-do-study-act quality improvement technique to understand our current malnutrition screening practices and institute an intervention to improve screening. To do this, we utilized a modified Malnutrition Universal Screening Tool (mMUST) and integrated this into the electronic health record. We then evaluated the intervention and the impact on IBD related clinical outcomes.Prior to the intervention, few patients with IBD were screened for malnutrition. However, the number of patients screened for malnutrition significantly improved with the study intervention and those who were identified as high-risk had increased nutrition follow up including serum micronutrient evaluations and referral to a dedicated registered dietician.This study demonstrated the feasibility and impact of a malnutrition screening program in ambulatory IBD patients. Those patients identified as high risk for malnutrition who engaged in nutrition care had improved clinical outcomes including reduced hospitalizations and emergency room visits.

Background and Aims Integrated IBD care is effective but not routinely implemented. Validated methods that simultaneously address mind and body targets such as resilience may improve access and outcomes. We describe the development and implementation of the GRITTTM Method and its impact on resilience, health care resource utilization (HCRU) and opioid use in IBD. Methods Consecutive patients from an academic IBD center were evaluated for low resilience based on provider referral. Low resilience patients were invited to participate in the GRITTTM program. Primary outcome was % reduction in HCU. Secondary outcomes were change in resilience, corticosteroid and opioid use. Patients were allocated into 2 groups for analysis: GRITT Participants (GP) and Non-Participants (NP). Clinical data and HCU in the year prior to enrollment were collected at baseline and 12 months. One-way repeated measures MANCOVA evaluated group X time interactions for the primary outcome. Effect size was calculated for changes in resilience over time. Results Of 456 screened IBD patients 394 were eligible; 184 GP and 210 NP. GP had greater reduction in HCU than NP: 71% reduction in ED visits; 94% reduction in unplanned hospitalizations. There was a 49% reduction in opioid use and 73% reduction in corticosteroid use in GP. Resilience increased by 27.3 points (59%), yielding a large effect size (d=2.4). Conclusion Mind-body care that focuses on building resilience in the context of IBD care may be a novel approach to reduce unplanned health care utilization and opioid use but large, multi-center, randomized, controlled trials are needed.

BACKGROUND: Disability in patients with medically refractory ulcerative colitis (UC) after total proctocolectomy (TPC) with ileal pouch anal anastomosis (IPAA) is not well understood. The aim of this study was to compare disability in patients with IPAA vs medically managed UC, and identify predictors of disability. METHODS: This was a multi-center cross-sectional study performed at five academic institutions in New York City. Patients with medically or surgically treated UC were recruited. Clinical and socioeconomic data were collected and the inflammatory bowel disease disability index (IBD-DI) was administered to eligible patients. Predictors of moderate-severe disability (IBD-DI≥35) were assessed in univariable and multivariable models. RESULTS: A total of 94 patients with IPAA and 128 patients with medically managed UC completed the IBD-DI. Among patients with IPAA and UC, 35 (37.2%) and 30 (23.4%) had moderate-severe disability, respectively. Patients with IPAA had significantly greater IBD-DI scores compared to patients with medically managed UC (29.8 vs 17.9, p

Background & Aims We aimed to compare safety and effectiveness of vedolizumab to tumor necrosis factor (TNF)-antagonist therapy in ulcerative colitis in routine practice. Methods A multicenter, retrospective, observational cohort study (May 2014 to December 2017) of ulcerative colitis patients treated with vedolizumab or TNF-antagonist therapy. Propensity score weighted comparisons for development of serious adverse events and achievement of clinical remission, steroid-free clinical remission, and steroid-free deep remission. A priori determined subgroup comparisons in TNF-antagonist–naive and –exposed patients, and for vedolizumab against infliximab and subcutaneous TNF-antagonists separately. Results A total of 722 (454 vedolizumab, 268 TNF antagonist) patients were included. Vedolizumab-treated patients were more likely to achieve clinical remission (hazard ratio [HR], 1.651; 95% confidence interval [CI], 1.229-2.217), steroid-free clinical remission (HR, 1.828; 95% CI, 1.135-2.944), and steroid-free deep remission (HR, 2.819; 95% CI, 1.496-5.310) than those treated with TNF antagonists. Results were consistent across subgroup analyses in TNF-antagonist–naive and −exposed patients, and for vedolizumab vs infliximab and vs subcutaneous TNF-antagonist agents separately. Overall, there were no statistically significant differences in the risk of serious adverse events (HR, 0.899; 95% CI, 0.502-1.612) or serious infections (HR, 1.235; 95% CI, 0.608-2.511) between vedolizumab-treated and TNF-antagonist−treated patients. However, in TNF-antagonist−naive patients, vedolizumab was less likely to be associated with serious adverse events than TNF antagonists (HR, 0.192; 95% CI, 0.049-0.754). Conclusions Treatment of ulcerative colitis with vedolizumab is associated with higher rates of remission than treatment with TNF-antagonist therapy in routine practice, and lower rates of serious adverse events in TNF-antagonist−naive patients.

Inflammatory bowel diseases (IBDs), including Crohn’s disease and ulcerative colitis, are chronic, progressive, immune-mediated diseases of adults and children that have no cure. IBD can cause significant morbidity and lead to complications such as strictures, fistulas, infections, and cancer. In children, IBD can also result in growth impairment and pubertal delays. IBD is highly heterogenous, with severity ranging from mild to severe and symptoms ranging from mild to debilitating. Delay in IBD diagnosis, especially in Crohn’s disease, is common and associated with adverse outcomes. Early diagnosis and prompt institution of treatment are the cornerstones for improving outcomes and maximizing health. Early diagnosis requires a low threshold of suspicion and red flags to guide early specialist referral at the primary provider level. Although the armamentarium of IBD medications is growing, many patients will not respond to treatment, and the selection of first-line therapy is critical. Risk stratification of disease severity, based on clinical, demographic, and serologic markers, can help guide selection of first-line therapy. Clinical decision support tools, genomics, and other biomarkers of response to therapy and risk of adverse events are the future of personalized medicine. After starting appropriate therapy, it is important to confirm remission using objective end points (treat to target) with continued control of inflammation with adjustment of therapy using surrogate biomarkers (tight control). Lastly, IBD therapy extends far beyond medications, and other aspects of the overall health and wellbeing of the patient are critical. These include preventive health, nutrition, and psychobehavioral support addressing patients’ concerns around complementary therapy and medication adherence, prevention of disability, and ensuring open communication.

On March 11, 2020 the World Health Organization declared the 2019 novel coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) epidemic a global pandemic. Physicians, scientists, and patients scrambled to gain an understanding of the implications of this dire situation, and societies and organizations tried to provide guidance of best practices and precautions. In the inflammatory bowel disease community (IBD), the International Organization for the study of IBD (IOIBD) convened their expert members and performed a RAND panel assessment to develop recommendations for patients and providers. Others developed an international open registry to collect data about patients with IBD who developed Coronavirus Disease (COVID-19), the Surveillance Epidemiology of COVID-19 Under Research Exclusion (SECURE-IBD), in order to collect evidence on how COVID-19 impacted IBD patients. To date, SECURE-IBD has amassed 3,493 cases with outcomes3 and published initial analyses. In addition, there were multiple articles published with individual or multi-center experiences, city or regional experiences, and many case reports about IBD or immunemediated disease outcomes. Separately, there was significant activity by translational and basic scientists working to define and describe the pathophysiology of SARS-CoV-2 infections.

Approximately 20% of patients with ulcerative colitis (UC) who undergo total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA) develop chronic pouch inflammation (CPI).

Patients with immune-mediated inflammatory diseases such as inflammatory bowel disease (IBD) on immunosuppressive and biologic therapies were largely excluded from severe acute respiratory syndrome coronavirus-2 messenger RNA vaccine trials.We evaluated adverse events (AE) after messenger RNA vaccination in 246 adults with IBD participating in a longitudinal vaccine registry.In general, AE frequency was similar to that reported in the general population. AEs were more common among younger patients and those with previous COVID-19. AEs were less common in individuals receiving advanced therapies with biologics or small-molecule inhibitors.Those with IBD and other immune-mediated inflammatory diseases can be reassured that the AE risk is likely not increased, and may be reduced, while on advanced therapies.

We have previously described a prognostic transcriptional signature in CD8 T cells that separates patients with IBD into two phenotypically distinct subgroups, termed IBD1 and IBD2. Here we sought to develop a blood-based test that could identify these subgroups without cell separation, and thus be suitable for clinical use in Crohn's disease (CD) and ulcerative colitis (UC).Patients with active IBD were recruited before treatment. Transcriptomic analyses were performed on purified CD8 T cells and/or whole blood. Phenotype data were collected prospectively. IBD1/IBD2 patient subgroups were identified by consensus clustering of CD8 T cell transcriptomes. In a training cohort, machine learning was used to identify groups of genes ('classifiers') whose differential expression in whole blood recreated the IBD1/IBD2 subgroups. Genes from the best classifiers were quantitative (q)PCR optimised, and further machine learning was used to identify the optimal qPCR classifier, which was locked down for further testing. Independent validation was sought in separate cohorts of patients with CD (n=66) and UC (n=57).In both validation cohorts, a 17-gene qPCR-based classifier stratified patients into two distinct subgroups. Irrespective of the underlying diagnosis, IBDhi patients (analogous to the poor prognosis IBD1 subgroup) experienced significantly more aggressive disease than IBDlo patients (analogous to IBD2), with earlier need for treatment escalation (hazard ratio=2.65 (CD), 3.12 (UC)) and more escalations over time (for multiple escalations within 18 months: sensitivity=72.7% (CD), 100% (UC); negative predictive value=90.9% (CD), 100% (UC)).This is the first validated prognostic biomarker that can predict prognosis in newly diagnosed patients with IBD and represents a step towards personalised therapy.

Polygenic and environmental factors are underlying causes of inflammatory bowel disease (IBD). We hypothesized that integration of the genetic loci controlling a metabolite's abundance, with known IBD genetic susceptibility loci, may help resolve metabolic drivers of IBD.We measured the levels of 1300 metabolites in the serum of 484 patients with ulcerative colitis (UC) and 464 patients with Crohn's disease (CD) and 365 controls. Differential metabolite abundance was determined for disease status, subtype, clinical and endoscopic disease activity, as well as IBD phenotype including disease behavior, location, and extent. To inform on the genetic basis underlying metabolic diversity, we integrated metabolite and genomic data. Genetic colocalization and Mendelian randomization analyses were performed using known IBD risk loci to explore whether any metabolite was causally associated with IBD.We found 173 genetically controlled metabolites (metabolite quantitative trait loci, 9 novel) within 63 non-overlapping loci (7 novel). Furthermore, several metabolites significantly associated with IBD disease status and activity as defined using clinical and endoscopic indexes. This constitutes a resource for biomarker discovery and IBD biology insights. Using this resource, we show that a novel metabolite quantitative trait locus for serum butyrate levels containing ACADS was not supported as causal for IBD; replicate the association of serum omega-6 containing lipids with the fatty acid desaturase 1/2 locus and identify these metabolites as causal for CD through Mendelian randomization; and validate a novel association of serum plasmalogen and TMEM229B, which was predicted as causal for CD.An exploratory analysis combining genetics and unbiased serum metabolome surveys can reveal novel biomarkers of disease activity and potential mediators of pathology in IBD.

The coronavirus disease 2019 (COVID-19) has affected more than 29 million people and led to more than 542,000 deaths in the United States.1 Older age, comorbidities, and racial and ethnic minority status are associated with severe COVID-19.2 Among patients with inflammatory bowel disease (IBD), racial and ethnic minorities have worse outcomes, mediated in part by inequitable health care access.3 Racial and ethnic minority patients with IBD and COVID-19 may be an especially vulnerable population. The purpose of this study was to evaluate racial and ethnic disparities in COVID-19 outcomes among IBD patients and the impact of non-IBD comorbidities on observed disparities.

Introduction The emotional health of patients with IBD has been difficult to elucidate in routine IBD care, but is critical to medication adoption, adherence and self-management. Patients often are unsure how to communicate their preferences and concerns to their providers in ways that could directly inform shared decision making. Photovoice is an established research methodology used to give vulnerable patients a voice through alternative communication strategies, but has not been previously used in IBD. Aim Our goal was to determine the acceptability and feasibility of developing a communication tool using photovoice in an IBD clinic. The ultimate goal is to adapt Photovoice to facilitate doctor – patient communication around treatment and wellness goals in the clinic setting. Methods We recruited patients at a single tertiary care IBD center in 2019 to participate in a pilot Photovoice study. Patients received a digital camera, training on basic usage and 10 disease specific prompts focused on goals/strategies they used to manage IBD. For example, “What is the most important thing for your doctor to know about you?” Patients then participated in in-depth interviews where they shared the photos they took and described rationale for their photo choice. The interviews lasted approximately one hour and were audio recorded and professionally transcribed. Three analysts coded transcripts for themes using qualitative analysis software QSR NVivo 11. Subsequently, five physicians were recruited and also participated in in-depth interviews to gauge provider feasibility of incorporating Photovoice into clinical practice. Results Fifteen patients were enrolled, median age 28 IQR (24–40), 66% women, 86% white. Three patients (20%) identified as Hispanic and six (40%) identified as Ashkenazi Jewish. Fourteen transcripts were available for analysis (9 patient and 5 providers). A total of 87 photos were taken and reviewed with patients, with a subset of 15 photos reviewed with physicians. The general themes from patients were physical and psychological aspects of disease, logistical/practical aspects, and future with IBD. Physician response was overwhelmingly supportive of incorporating Photovoice into clinical practice and suggested several ways to incorporate: 1. As discrete parts of visits to foster goal-setting and identify patient priorities. 2. Displayed in the hallways of the clinic to foster community among patients. 3. As part of electronic medical records or as prompts in the waiting room to generate referrals to other resources like psychotherapy, social work and diet consults. Conclusions Photovoice is a feasible methodology for patients with IBD and acceptable to providers to use in a clinical setting. Photovoice may help providers identify patient concerns and tailor their communication and enhance approaches to shared decision making.

Despite improvements in medical management, 10%-15% of patients with ulcerative colitis (UC) require total proctocolectomy (TPC) with ileal pouch anal anastomosis (IPAA) for refractory disease.1 Acute pouchitis is the most common post-IPAA inflammatory condition, with cumulative incidence of 45% at 5 years.2 Up to 20%-30% of patients develop chronic pouch inflammation (CPI), categorized as antibiotic responsive, antibiotic refractory, or Crohn's disease-like (CDL).3.

The coronavirus disease 2019 (COVID-19) pandemic caused by the highly infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) presents most often with mild clinical symptoms, but the severe forms are of major concern.1 SARS-CoV-2 enters human cells via the angiotensin-converting enzyme 2 receptor, expressed on epithelial and endothelial cells.2 Because the highest angiotensin-converting enzyme 2 expression is in the terminal ileum and colon, and up-regulated further during inflammation, and many COVID-19 patients experience gastrointestinal symptoms, longitudinal data are necessary to determine whether inflammatory bowel disease (IBD) patients are at risk for severe or complicated COVID-19. A recent analysis in IBD patients from the Surveillance Epidemiology of Coronavirus Under Research Exclusion for Inflammatory Bowel Disease (SECURE-IBD) registry showed older age, steroid medication, and comorbidities as risk factors for severe evolution, and the same study showed that the 29 IBD patients younger than age 20 had only mild disease courses.3 This report describes the disease course of COVID-19 in an expanded sample of pediatric IBD patients from 2 international databases.

Despite the recent developments in the diagnosis and management of inflammatory bowel diseases (IBD), patients still suffer from disabling bowel symptoms and significant disease complications and many questions remain to improve their care. IBD is a chronic disease, whose management could be divided into the five different stages of chronic diseases, ranging from the pre-treatment evaluation phase to the induction therapy, maintenance therapy, monitor and re-establishment of control and the cessation of the disease. Reconciling these phases with the current unmet needs in IBD could help tailor priorities for research. In this review, some of the unanswered questions in the management of both Crohn’s Disease and Ulcerative Colitis will be addressed, by following this paradigm of chronic diseases’ management.

Background & aimsWe created and validated a clinical decision support tool (CDST) to predict outcomes of vedolizumab therapy for ulcerative colitis (UC).MethodsWe performed logistic regression analyses of data from the GEMINI 1 trial, from 620 patients with UC who received vedolizumab induction and maintenance therapy (derivation cohort), to identify factors associated with corticosteroid-free remission (full Mayo score of 2 or less, no subscore above 1). We used these factors to develop a model to predict outcomes of treatment, which we called the vedolizumab CDST. We evaluated the correlation between exposure and efficacy. We validated the CDST in using data from 199 patients treated with vedolizumab in routine practice in the United States from May 2014 through December2017.ResultsAbsence of exposure to a tumor necrosis factor (TNF) antagonist (+3 points), disease duration of 2 y or more (+3 points), baseline endoscopic activity (moderate vs severe) (+2 points), and baseline albumin concentration (+0.65 points per 1 g/L) were independently associated with corticosteroid-free remission during vedolizumab therapy. Patients in the derivation and validation cohorts were assigned to groups of low (CDST score, 26 points or less), intermediate (CDST score, 27-32 points), or high (CDST score, 33 points or more) probability of vedolizumab response. We observed a statistically significant linear relationship between probability group and efficacy (area under the receiver operating characteristic curve, 0.65), as well as drug exposure (P < .001) in the derivation cohort. In the validation cohort, a cutoff value of 26 points identified patients who did not respond to vedolizumab with high sensitivity (93%); only the low and intermediate probability groups benefited from reducing intervals of vedolizumab administration due to lack of response (P = .02). The vedolizumab CDST did not identify patients with corticosteroid-free remission during TNF antagonist therapy.ConclusionsWe used data from a trial of patients with UC to develop a scoring system, called the CDST, which identified patients most likely to enter corticosteroid-free remission during vedolizumab therapy, but not anti-TNF therapy. We validated the vedolizumab CDST in a separate cohort of patients in clinical practice. The CDST identified patients most likely to benefited from reducing intervals of vedolizumab administration due to lack of initial response. ClinicalTrials.gov no: NCT00783718.

Background and Aims The impact of Coronavirus disease 2019 (COVID-19) on patients with inflammatory bowel disease (IBD) is unknown. We sought to characterize the clinical course of COVID-19 among patients with IBD and evaluate the association among demographics, clinical characteristics, and immunosuppressant treatments on COVID-19 outcomes. Methods Surveillance Epidemiology of Coronavirus Under Research Exclusion for Inflammatory Bowel Disease (SECURE-IBD) is a large, international registry created to monitor outcomes of patients with IBD with confirmed COVID-19. We calculated age-standardized mortality ratios and used multivariable logistic regression to identify factors associated with severe COVID-19, defined as intensive care unit admission, ventilator use, and/or death. Results 525 cases from 33 countries were reported (median age 43 years, 53% men). Thirty-seven patients (7%) had severe COVID-19, 161 (31%) were hospitalized, and 16 patients died (3% case fatality rate). Standardized mortality ratios for patients with IBD were 1.8 (95% confidence interval [CI], 0.9–2.6), 1.5 (95% CI, 0.7–2.2), and 1.7 (95% CI, 0.9–2.5) relative to data from China, Italy, and the United States, respectively. Risk factors for severe COVID-19 among patients with IBD included increasing age (adjusted odds ratio [aOR], 1.04; 95% CI, 1.01–1.02), ≥2 comorbidities (aOR, 2.9; 95% CI, 1.1–7.8), systemic corticosteroids (aOR, 6.9; 95% CI, 2.3–20.5), and sulfasalazine or 5-aminosalicylate use (aOR, 3.1; 95% CI, 1.3–7.7). Tumor necrosis factor antagonist treatment was not associated with severe COVID-19 (aOR, 0.9; 95% CI, 0.4–2.2). Conclusions Increasing age, comorbidities, and corticosteroids are associated with severe COVID-19 among patients with IBD, although a causal relationship cannot be definitively established. Notably, tumor necrosis factor antagonists do not appear to be associated with severe COVID-19.
