Why Symptoms Linger in Quiescent Crohn's Disease: Investigating the Impact of Sulfidogenic Microbes and Sulfur Metabolic Pathways.

Introduction: Even in the absence of inflammation, persistent symptoms in patients with Crohn's disease (CD) are prevalent and worsen quality of life. We previously demonstrated enrichment in sulfidogenic microbes in quiescent Crohn's disease patients with ( qCD+S ) vs. without persistent GI symptoms ( qCD-S ). Thus, we hypothesized that sulfur metabolic pathways would be enriched in stool while differentially abundant microbes would be associated with important sulfur-metabolic pathways in qCD+S. Methods: We performed a multi-center observational study nested within SPARC IBD. Quiescent inflammation was defined by fecal calprotectin level <150 mcg/g. Persistent symptoms were defined by CD-PRO2. Active CD ( aCD ) and non-IBD diarrhea-predominant irritable bowel syndrome ( IBS-D ) were included as controls. Results: Thirty-nine patients with qCD+S, 274 qCD-S, 21 aCD, and 40 IBS-D underwent paired shotgun metagenomic sequencing and untargeted metabolomic profiling. The fecal metabolome in qCD+S was significantly different relative to qCD-S and IBS-D but not aCD. Patients with qCD+S were enriched in sulfur-containing amino acid pathways, including cysteine and methionine, as well as serine, glycine, and threonine. Glutathione and nicotinate/nicotinamide pathways were also enriched in qCD+S relative to qCD-S, suggestive of mitochondrial dysfunction, a downstream target of H 2 S signaling. Multi-omic integration demonstrated that enriched microbes in qCD+S were associated with important sulfur-metabolic pathways. Bacterial sulfur-metabolic genes, including CTH , isfD , sarD , and asrC , were dysregulated in qCD+S. Finally, sulfur metabolites with and without sulfidogenic microbes showed good accuracy in predicting presence of qCD+S. Discussion: Microbial-derived sulfur pathways and downstream mitochondrial function are perturbed in qCD+S, which implicate H 2 S signaling in the pathogenesis of this condition. Future studies will determine whether targeting H 2 S pathways results in improved quality of life in qCD+S. Key Messages: What is Already Known Even in the absence of inflammation, persistent gastrointestinal symptoms are common in Crohn's disease.The microbiome is altered in quiescent Crohn's disease patients with persistent symptoms, but the functional significance of these changes is unknown. What is New Here Sulfur metabolites and sulfur metabolic pathways were enriched in stool in quiescent Crohn's disease patients with persistent symptoms.Multi-omic integration showed enriched microbes were associated with important sulfur metabolic pathways in quiescent Crohn's disease patients with persistent symptoms. How Can This Study Help Patient Care Strategies to decrease sulfidogenic microbes and associated sulfur metabolic pathways could represent a novel strategy to improve quality of life in quiescent Crohn's disease with persistent GI symptoms.

Understanding the Perspectives and Experiences of Patients with Acute Severe Ulcerative Colitis in the Hospital: A Qualitative Analysis.

INTRODUCTION: Acute severe ulcerative colitis (ASUC) is a life-treating presentation of ulcerative colitis (UC) that requires prompt initiation of treatment to avoid complication. Unfortunately, outcomes for ASUC are suboptimal, with as many as 20-30% of patients requiring colectomy. This can be challenging for patients and highlights the need to understand patient experiences and perspectives navigating ASUC. METHODS: A qualitative descriptive study utilizing semi-structured interviews was conducted to understand perspectives and experiences of patients navigating ASUC. Adult patients hospitalized for ASUC between January 2017 and March 2024 were eligible. Interviews were conducted both retrospectively among patients with a recent hospitalization and prospectively among patients within 24 h of hospitalization for ASUC. Interviews were analyzed using a well-established hybrid inductive-deductive approach. RESULTS: Thirty-four patients (44.2% response rate) hospitalized for ASUC were interviewed. Hybrid thematic analysis uncovered five major themes: (1) the pervasive impact of UC on QoL and mental health, (2) challenges associated with navigating uncertainty, (3) prioritizing colon preservation, (4) bridging the divide between outpatient expectations and inpatient realities, and (5) balancing rapid symptom improvement with steroid safety. Our findings advocate for transparent approach to care, emphasizing the need for effective communication, education, and better alignment with patient values and expectations. CONCLUSION: Five key themes were identified, each with significant implications for developing a more patient-centered approach to ASUC care. These themes captured meaningful insight into patient perceptions and experiences, identifying multiple areas for actionable interventions to improve care.

User guide for Social Determinants of Health Survey data in the All of Us Research Program.

OBJECTIVES: Integration of social determinants of health into health outcomes research will allow researchers to study health inequities. The All of Us Research Program has the potential to be a rich source of social determinants of health data. However, user-friendly recommendations for scoring and interpreting the All of Us Social Determinants of Health Survey are needed to return value to communities through advancing researcher competencies in use of the All of Us Research Hub Researcher Workbench. We created a user guide aimed at providing researchers with an overview of the Social Determinants of Health Survey, recommendations for scoring and interpreting participant responses, and readily executable R and Python functions. TARGET AUDIENCE: This user guide targets registered users of the All of Us Research Hub Researcher Workbench, a cloud-based platform that supports analysis of All of Us data, who are currently conducting or planning to conduct analyses using the Social Determinants of Health Survey. SCOPE: We introduce 14 constructs evaluated as part of the Social Determinants of Health Survey and summarize construct operationalization. We offer 30 literature-informed recommendations for scoring participant responses and interpreting scores, with multiple options available for 8 of the constructs. Then, we walk through example R and Python functions for relabeling responses and scoring constructs that can be directly implemented in Jupyter Notebook or RStudio within the Researcher Workbench. Full source code is available in supplemental files and GitHub. Finally, we discuss psychometric considerations related to the Social Determinants of Health Survey for researchers.

The Microbiome in Quiescent Crohn's Disease With Persistent Symptoms Show Disruptions in Microbial Sulfur and Tryptophan Pathways.

Background and Aims: Even in the absence of inflammation, persistent symptoms in Crohn's disease (CD) are prevalent and worsen quality of life. Amongst patients without inflammation (quiescent CD), we hypothesized that microbial community structure and function, including tryptophan metabolism, would differ between patients with persistent symptoms (qCD + S) and without persistent symptoms (qCD-S). Methods: We performed a multicenter observational study nested within the Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease. Quiescent inflammation was defined by fecal calprotectin level <150 mcg/g. Persistent symptoms were defined by Crohn's Disease Patient-Reported Outcome-2. Active CD, diarrhea-predominant irritable bowel syndrome, and healthy controls were included as controls. Stool samples underwent whole-genome shotgun metagenomic sequencing. Results: Thirty-nine patients with qCD + S, 274 qCD-S, 21 active CD, 40 diarrhea-predominant irritable bowel syndrome, and 50 healthy controls were included for analysis. Patients with qCD + S had a less-diverse microbiome. Furthermore, patients with qCD + S showed significant enrichment of bacterial species that are normal inhabitants of the oral microbiome (eg Rothia dentocariosa, Fusobacterium nucleatum) and sulfidogenic microbes (eg Prevotella copri, Bilophila spp.). Depletion of important butyrate and indole producers (eg Eubacterium rectale, Faecalibacterium prausnitzii) was also noted in qCD + S. Potential metagenome-related functional changes in cysteine and methionine metabolism, ATP transport, and redox reactions were disturbed in qCD + S, also suggestive of altered sulfur metabolism. Finally, qCD + S showed significant reductions in bacterial tnaA genes, which mediate tryptophan metabolism to indole, and significant tnaA allelic variation compared with qCD-S. Conclusion: The microbiome in qCD + S showed significant differences in sulfidogenesis, butyrate producers, and typically oral microbes compared to qCD-S and active CD. These results suggest that inflammation may lead to durable microbiome alterations which may mediate persistent symptoms through testable mechanisms.

Remote Between Visit Monitoring in Inflammatory Bowel Disease Care: A Qualitative Study of CAPTURE-IBD Participants and Care Team Members.

Introduction: We recently showed that CAPTURE-inflammatory bowel disease (IBD)-a care coordination intervention comprised of routine remote monitoring of patient-reported outcomes (PRO) and a care coordinator-triggered care pathway-was more effective at reducing symptom burden for patients with IBD compared to usual care. We aimed to understand how patients and care team providers experienced the intervention and evaluate purported mechanisms of action to plan for future implementation. Methods: In this study, 205 patients were randomized to CAPTURE-IBD (n = 100) or usual care(n = 105). We conducted semi-structured interviews with 16 of the 100 participants in the CAPTURE-IBD arm and 5 care team providers to achieve thematic saturation. We used qualitative rapid analysis to generate a broad understanding of experiences, perceived impact, the coordinator role, and suggested improvements. Results: Findings highlight that the intervention was acceptable and user-friendly, despite concerns regarding increased nursing workload. Both participants and care team providers perceived the intervention as valuable in supporting symptom monitoring, psychosocial care, and between-visit action plans to improve IBD care and health outcomes. However, few participants leveraged the care coordinator as intended. Finally, participants reported that the intervention could be better tailored to capture day-to-day symptom changes and to meet the needs of patients with specific comorbid conditions (eg, ostomies). Conclusions: Remote PRO monitoring is acceptable and may be valuable in improving care management, promoting tight control, and supporting whole health in IBD. Future efforts should focus on testing and implementing refined versions of CAPTURE-IBD tailored to different clinical settings.

Insurer-Mandated Medication Utilization Barriers are Associated With Decreased Insurance Satisfaction and Adverse Clinical Outcomes: An Inflammatory Bowel Disease Partners Survey.

INTRODUCTION: Insurer-mandated barriers to timely initiation of advanced therapies used to treat inflammatory bowel disease (IBD) have been shown to worsen clinical outcomes and increase healthcare utilization, yet rarely alter the medication ultimately prescribed. METHODS: We conducted a survey within the IBD Partners longitudinal cohort to evaluate the frequency and patient-reported impacts of medication utilization barriers on insurance satisfaction and clinical outcomes. Barriers included medication denials, prior authorizations, and forced medication switches. Variables associated with insurance satisfaction, measured on a 1-7 Likert scale, were identified. The association between insurance-related barriers and downstream clinical outcomes (surgery, corticosteroid requirement, and disease activity) were evaluated. RESULTS: Two thousand seventeen patients (age 45 [interquartile range 34-58] years, 73% female) were included. Seventy-two percent experienced an insurer-mandated barrier, most commonly prior authorizations (51%). Fifteen percent were denied an IBD medication by their insurer, 22% experienced an insurance-related gap in therapy, and 8% were forced by their insurer to switch from an effective medication. Insurance satisfaction was negatively associated with medication denials, prior authorization-related delays, gaps in therapy, and high-deductible health plan coverage. In the year following the initial survey, several insurance barriers were linked to negative downstream clinical outcomes, including prior authorizations associated with corticosteroid rescue (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.25-4.00), forced medication switches associated with continued disease activity (OR 3.28, 95% CI 1.56-6.89), and medication denials associated with IBD-related surgery (OR 8.92, 95% CI 1.97-40.39). DISCUSSION: These data illustrate the frequency and negative impacts of insurer-mandated medication barriers on patients with IBD, including decreased insurance satisfaction and negative downstream clinical outcomes.

Legalization of Cannabis Does Not Reduce Opioid Prescribing in Patients With Inflammatory Bowel Disease: A Difference-in-Difference Analysis.

INTRODUCTION: Cannabis may provide inflammatory bowel disease (IBD) patients with an alternative to opioids for pain. METHODS: We conducted a difference-in-difference analysis using MarketScan. Changes over time in rates of opioid prescribing were compared in states with legalized cannabis to those without. RESULTS: We identified 6,240 patients with IBD in states with legalized cannabis and 79,272 patients with IBD in states without legalized cannabis. The rate of opioid prescribing decreased over time in both groups and were not significantly different (attributed differential = 0.34, confidence interval -13.02 to 13.70, P = 0.96). DISCUSSION: Opioid prescribing decreased from 2009 to 2016 among patients with IBD in both states with legalized and state without legalized cannabis, similar to what has been observed nationally across a variety of diseases. Cannabis legalization was not associated with a lower rate of opioid prescribing for patients with IBD.

Association of Bowel Urgency With Quality-of-Life Measures in Patients With Moderately-to-Severely Active Ulcerative Colitis: Results From Phase 3 LUCENT-1 (Induction) and LUCENT-2 (Maintenance) Studies.

Background: Improvement in bowel urgency (BU) was associated with better clinical outcomes in phase 3 LUCENT-1 (induction) and LUCENT-2 (maintenance) studies in moderately-to-severely active ulcerative colitis (UC). We assessed association of BU with quality-of-life (QoL) outcomes. Methods: LUCENT-1: 1162 patients randomized 3:1 to intravenous mirikizumab 300 mg or placebo every 4 weeks (Q4W) for 12 weeks. LUCENT-2: 544 mirikizumab induction responders re-randomized 2:1 to subcutaneous mirikizumab 200 mg or placebo Q4W through Week (W) 40 (W52 of continuous treatment). Patients reported BU severity in the past 24 hours using a validated Urgency Numeric Rating Scale (NRS). In patients with baseline Urgency NRS ≥3, the association between BU Clinically Meaningful Improvement (CMI; ≥3-point decrease) and remission (score 0 or 1) with patient-reported outcomes was assessed at W12 and W52. Results: A significantly greater proportion of patients with versus without BU Remission achieved IBDQ remission (W12: 87.3% vs 42.7%, P < .0001; W52: 91.4% vs 45.5%, p < .0001). Similarly, BU Remission was associated with more patients achieving CMI in SF-36 Physical Component Summary (W12: 69.0% vs 44.4%, P < .0001; W52: 77.5% vs 42.1%, P < .0001) and Mental Component Summary (W12: 53.5% vs 41.0%, P = .0019; W52: 62.0% vs 38.3%, P < .0001) scores. At W12 and W52, patients with BU CMI or Remission showed significant improvements in EQ-5D-5L and Work Productivity and Activity Impairment:UC scores. Significant improvements were also seen in fatigue, abdominal pain, and nocturnal stool. Conclusions: In patients with moderately-to-severely active UC, improvement in BU was associated with improved QoL in phase 3 LUCENT-1 and LUCENT-2 studies. Clinical Studies: LUCENT-1: NCT03518086; LUCENT-2: NCT03524092.

Humoral immune response and safety of SARS-CoV-2 vaccination in very early onset inflammatory bowel disease.

Children with very early onset inflammatory bowel disease (VEO-IBD) may respond differently to coronavirus disease 2019 (COVID-19) immunization compared to healthy children or other patients with IBD. We recruited children with VEO-IBD <6 years of age and younger following receipt of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Demographics, IBD characteristics, medication use, adverse events (AEs) and IBD exacerbations were collected. Blood draws (optional) were obtained for measurement of antireceptor binding domain (RBD) IgG antibodies following vaccination. Of 41 participants, none required emergency department visit or hospitalization due to AE, and only one experienced IBD exacerbation. Detectable antibody was present in 19/19 participants who provided blood sample; 6/7 participants (86%) had durable humoral response 12 months postvaccination. Children with VEO-IBD experience robust humoral immune response to COVID-19 immunization. Severe AEs were rare. These findings provide reassurance that children with VEO-IBD respond well and safely to SARS-CoV-2 vaccination.

Long-Term Effectiveness and Durability of COVID-19 Vaccination Among Patients With Inflammatory Bowel Disease.

BACKGROUND AND AIMS: COVID-19 vaccination prevents severe disease in most patients with inflammatory bowel disease (IBD), but immunosuppressive medications can blunt serologic response. We followed adults with IBD for >1 year post-COVID-19 vaccination to describe factors associated with SARS-CoV-2 infection after vaccination, evaluate for a protective SARS-CoV-2 antibody level, characterize SARS-CoV-2 antibody persistence, and identify factors associated with humoral immune response durability. METHODS: Using a prospective cohort of COVID-19 immunized adults with IBD, we analyzed factors associated with SARS-CoV-2 infection after vaccination. We evaluated for an association between SARS-CoV-2 antibody level 12 weeks postvaccination and subsequent SARS-CoV-2 infection and assessed for a threshold of protection using receiver-operating characteristic curve analysis. We then conducted a separate analysis evaluating factors associated with persistence of SARS-CoV-2 antibodies 52 weeks postimmunization. RESULTS: Almost half (43%) of 1869 participants developed COVID-19 after vaccination, but most infections were mild, and <1% required hospitalization. Older age and corticosteroid use were associated with a decreased risk of SARS-CoV-2 infection postvaccination (50-59 years of age vs 18-29 years of age: adjusted hazard ratio, 0.57; 95% confidence interval, 0.44-0.74; steroid users vs nonusers: adjusted hazard ratio, 0.58; 95% confidence interval, 0.39-0.87). Most (98%) participants had detectable antibody levels at 52 weeks postvaccination. Antibody levels at 12 weeks and number of vaccine doses were positively associated with higher antibody levels at 52 weeks, while anti-tumor necrosis factor α therapy was negatively associated. CONCLUSIONS: COVID-19 vaccination generates an effective and durable protective response for the vast majority of adults with IBD, including vulnerable populations such as corticosteroid users and older individuals. Patients with IBD benefit from COVID-19 booster vaccination.

Extended Induction and Prognostic Indicators of Response in Patients Treated with Mirikizumab with Moderately to Severely Active Ulcerative Colitis in the LUCENT Trials.

BACKGROUND: Efficacy and safety of mirikizumab, a p19-targeted anti-interleukin-23 monoclonal antibody, for moderately to severely active ulcerative colitis was demonstrated previously. We evaluated clinical response, baseline characteristics, and clinical status in patients not responding by 12 weeks (W) of induction who then received extended induction treatment. METHOD: Patients unresponsive to 300 mg of intravenous (IV) mirikizumab every 4 weeks by W12 received 3 additional 300 mg IV doses every 4 weeks. Week-4 responders received 200 mg mirikizumab every 4 weeks subcutaneously until W52. Patients responding by W12 but subsequently losing response received rescue therapy with 300 mg IV for 3 doses every 4 weeks. Logistic regression modelling was performed for patients not achieving W12 clinical response to assess baseline characteristics and W12 efficacy parameters and potential prognostic factors of clinical response at W24. RESULTS: Of patients not achieving clinical response during induction, 53.7% achieved response following extended induction. After 52W, 72.2%, 43.1%, and 36.1% of patients achieved clinical response, endoscopic, and clinical remission, respectively. Of induction responders who subsequently lost response, 63.2% and 36.8% achieved symptomatic response and remission, respectively, after receiving rescue therapy No prior biologic or tofacitinib treatment, no immunomodulators at baseline, age older than 40 years, and W12 modified Mayo Score improvement were positively associated with a response to extended induction. The safety profile was similar to initial induction, with 38.3% treatment emergent adverse events, mostly mild. CONCLUSION: With "extended induction," total of 80.3% mirikizumab-treated patients achieved clinical response by W24. Potential prognostic factors determining response include disease severity, disease phenotype, C-reactive protein, and previous biologic therapy.

Extended induction with mirikizumab led to clinical response in more than half of primary nonresponders. Intravenous reinduction therapy in patients losing response during treatment led to more than 60% achieving symptomatic response, confirming the clinical benefit of these treatment strategies for harder to treat patients.

Effectiveness of Upadacitinib for Patients With Acute Severe Ulcerative Colitis: A Multicenter Experience.

INTRODUCTION: A significant proportion of patients with acute severe ulcerative colitis (ASUC) require colectomy. METHODS: Patients with ASUC treated with upadacitinib and intravenous corticosteroids at 5 hospitals are presented. The primary outcome was 90-day colectomy rate. Secondary outcomes included frequency of steroid-free clinical remission, adverse events, and all-cause readmissions. RESULTS: Of the 25 patients with ASUC treated with upadacitinib, 6 (24%) patients underwent colectomy, 15 (83%) of the 18 patients with available data and who did not undergo colectomy experienced steroid-free clinical remission (1 patient did not have complete data), 1 (4%) patient experienced a venous thromboembolic event, while 5 (20%) patients were readmitted. DISCUSSION: Upadacitinib along with intravenous corticosteroids may be an effective treatment for ASUC.

Changes in Therapy Are Not Associated With Increased Remission in Patients With Crohn's Disease of the Pouch.

INTRODUCTION: There is a paucity of data on the real-world effectiveness of therapies in patients with Crohn's disease of the pouch. METHODS: This was a prospective multicenter study evaluating the primary outcome of remission at 12 months of therapy for Crohn's disease of the pouch. RESULTS: One hundred thirty-four patients were enrolled. Among the 77 patients with symptoms at baseline, 35 (46.7%) achieved remission at 12 months. Of them, 12 (34.3%) changed therapy. There was no significant association between therapy patterns and remission status. DISCUSSION: Approximately 50% with symptoms at enrollment achieved clinical remission at 12 months, most of whom did so without a change in therapy.

Efficacy and safety of upadacitinib for 16-week extended induction and 52-week maintenance therapy in patients with moderately to severely active ulcerative colitis.

BACKGROUND: Upadacitinib is an oral, selective Janus kinase inhibitor. AIM: To assess the efficacy and safety of upadacitinib in patients with moderate-to-severe ulcerative colitis following 16-week extended induction therapy, and 52-week maintenance therapy in patients achieving clinical response after 16-week extended induction therapy METHODS: Patients without clinical response to 8 weeks' upadacitinib 45 mg once daily induction therapy in two induction trials were eligible for an additional 8 weeks of therapy. Patients achieving clinical response at Week 16 were subsequently re-randomised (1:1) to upadacitinib 15 or 30 mg once daily for 52-week maintenance therapy. Efficacy was assessed at induction Week 16 (integrated) and maintenance Week 52; safety was assessed throughout. RESULTS: Overall, 127/663 (19.2%) patients did not achieve clinical response to upadacitinib 45 mg at Week 8 and received an additional 8 weeks of therapy; 75/127 (59.1%) subsequently achieved clinical response at Week 16 and entered the maintenance trial. At Week 52, 26.5% of patients receiving upadacitinib 15 mg, and 43.6% receiving 30 mg, achieved clinical remission; efficacy was observed across all other endpoints with both doses. Herpes zoster rates increased with longer duration (16 weeks) of exposure to upadacitinib 45 mg during induction compared with the same population during the first 8 weeks. No other new safety signals were observed, and results are otherwise consistent with the known safety profile of upadacitinib. CONCLUSIONS: Patients without clinical response after 8 weeks' upadacitinib 45 mg induction therapy, may benefit from an additional 8 weeks of therapy. CLINICAL TRIAL REGISTRATION: NCT02819635; NCT03653026.

Profiles of Web-based Portal Users with Inflammatory Bowel Disease.

BACKGROUND: Web-based portals can enhance communication between patients and providers to support IBD self-management and improve care. We aimed to identify portal use patterns of patients with inflammatory bowel disease (IBD) to inform future web portal-based interventions and portal design. METHODS: Patients with IBD receiving care at the University of Michigan between 2012 and 2021 were identified. Meta-data from electronic logs of each patient's most recent year of portal use were abstracted. Portal engagement was characterized in terms of intensity (ie, frequency of use); comprehensiveness (ie, number of portal functions used); and duration (ie, quarters per year of portal use). We used k-means clustering, a machine-learning technique, to identify groupings of portal users defined in terms of engagement features. RESULTS: We found 5605 patients with IBD who had accessed their portal account at least once. The average age was 41.2 years (SD 16.7), 3035 (54.2%) were female, and 2214 (39.5%) received immune-targeted therapies. We identified 3 patterns of portal engagement: (1) low intensity users (29.5%); (2) moderate intensity, comprehensive, and sustained users (63.3%); and (3) high intensity, comprehensive, sustained users (7.2%). Patients with more intense, comprehensive, and sustained use of the portal were older, female, with more comorbidities, and were more likely to receive immune-targeted therapies. CONCLUSION: Understanding distinct patterns of portal use can inform portal-based interventions and portal design. Patient portals may be particularly helpful in delivering assistance to those with comorbidities and those receiving immune-targeted therapies-many of whom demonstrate more intense, comprehensive, and sustained portal use.

Inflammatory bowel disease patients have varying patterns of web-based portal engagement that can be characterized into distinct groupings. Portals-based interventions may be particularly helpful for those with comorbidities or receiving immune-targeted therapies­many of whom demonstrate more intense, comprehensive, and sustained use.

Fecal calprotectin level is nonlinearly associated with GI pathogen detection in patients with and without inflammatory bowel disease.

Fecal calprotectin (FCP) is used to monitor inflammatory bowel disease (IBD) activity and can also be elevated in gastrointestinal infections. Our study's objective was to quantify the relationship between FCP levels and lab-confirmed infections in people with and without IBD. We performed a cross-sectional study at a tertiary-care center of all encounters during which FCP and gastrointestinal pathogen polymerase-chain reaction (GI PCR) panel testings were conducted. Using non-parametric tests and quantile regression, we compared the FCP levels by IBD status and pathogen detection. There were 3,347 encounters with FCP and GI PCR testings from 2,780 unique individuals between 1 August 2016 and 17 February 2022. Overall, 54.4% had IBD (n = 1,819). Pathogens were detected in 744 encounters (22.2%), and the detection rate did not differ by IBD status. Median FCP without IBD was significantly elevated when a pathogen was detected (64 vs 41 mg/kg, P = 0.0003, normal ≤50.0 mg/kg), but FCP with IBD was not significantly elevated when a pathogen was detected (299 vs 255 mg/kg, P = 0.207). In quantile regression adjusted for age and IBD, pathogen detection was only significantly associated with higher FCP in the lower two quartiles, though IBD remained significantly associated with higher FCP at all levels (P > 0.001). Pathogen detection by GI PCR is associated with elevated FCP, though this relationship is nonlinear and varies by IBD status. Our findings indicate that FCP may be an adjunct to, but not a substitute for, stool pathogen testing.

Use of Upadacitinib in 16 Tofacitinib-refractory Ulcerative Colitis Patients: A Single-center Case 2Series.

We present a case series of 16 patients with ulcerative colitis who received upadacitinib after failing tofacitinib. Five patients (36%) achieved steroid-free clinical remission. Five (62%) demonstrated endoscopic response, while 2 patients (25%) achieved endoscopic remission. Adverse events were low.

Are Depression and Anxiety Underdiagnosed in Socially Vulnerable Patients With Inflammatory Bowel Disease?

INTRODUCTION: Depression and anxiety are highly prevalent among individuals with inflammatory bowel disease (IBD); however, little is understood about how social determinants of health (SDOH) may impact mental health diagnoses in this population. The social vulnerability index (SVI) is a publicly available tool that can be used to study SDOH in IBD patients. METHODS: Home addresses from a retrospective cohort of IBD patients at a single center were used to geocode patients to their individual census tract and corresponding SVI. We used multivariable logistic regression to examine the relationship between SVI and comorbid mental health diagnoses in patients with IBD. Secondarily, data from standardized health questionnaires were then used to determine if patients were adequately screened for depression and anxiety. RESULTS: In all, 9644 patients were included; 18% had a diagnosis of depression, 21% anxiety, and 32% had a composite of "any mental health diagnosis." Depression (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.02-1.56) but not anxiety (OR, 0.87; 95% CI, 0.71-1.06) nor "any mental health diagnosis" (OR, 1.09; 95% CI, 0.92-1.30) was associated with higher levels of social vulnerability. However, overall rates of screening for depression and anxiety were low (15% and 8%, respectively), with the lowest screening rates among the most socially vulnerable (depression 8.2%, anxiety 6.3%). CONCLUSIONS: Disparities in the diagnoses of depression and anxiety for socially vulnerable patients with IBD exist. Awareness of these inequities is the first step toward developing interventions to improve mental health screening, eliminate barriers and bias, and promote referrals for appropriate mental health management.

Socially vulnerable patients with inflammatory bowel disease are more likely to be diagnosed with depression but not anxiety. However, overall rates of screening for depression and anxiety are low, particularly among more socially vulnerable patients.
