Background And Aims: We evaluated the association between endoscopic outcomes following risankizumab induction and subsequent rates of hospitalization and surgery through 52 weeks of risankizumab (both doses) maintenance therapy in patients with Crohn's disease (CD).

Methods: Patients with moderately to severely active CD and clinical response to 12-week risankizumab induction were rerandomized to continued therapy or drug withdrawal in the phase 3 FORTIFY maintenance trial. Incidence rates (events/100 person-years) of CD-related hospitalization and surgery, and the composite of both, through 52 weeks of maintenance were compared between patients achieving vs not achieving predefined endoscopic outcomes following induction.

Introduction: Bowel urgency has recently been recognized as a Crohn's disease (CD) symptom that substantially impacts patients' quality of life. The Urgency NRS is a single-item patient-reported outcome measure assessing bowel urgency severity in the past 24 h (0-10 scale). We aimed to evaluate the psychometric properties of the Urgency Numeric Rating Scale (NRS) in adults with moderately to severely active CD and to estimate thresholds for meaningful improvement and bowel urgency remission.

Article Synopsis
  • Therapeutic drug monitoring (TDM) for biologic therapies in inflammatory bowel disease (IBD) focuses on optimizing medication doses but faces challenges like identifying ideal drug levels and dealing with variability in drug response.
  • Recent advancements, including population pharmacokinetic/pharmacodynamic (PK/PD) modeling and model-informed precision dosing (MIPD) tools, as well as point-of-care testing and new software, present promising solutions to these challenges.
  • Implementing these innovations could lead to personalized dosing strategies, moving away from the current one-size-fits-all approach that doesn't meet the diverse needs of IBD patients.

Despite the fundamental role of bacterial strain variation in gut microbiota function, the number of unique strains of a species that can stably colonize the human intestine is still unknown for almost all species. Here we determine the strain richness (SR) of common gut species using thousands of sequenced bacterial isolates with paired metagenomes. We show that SR varies across species, is transferable by faecal microbiota transplantation, and is uniquely low in the gut compared with soil and lake environments.

Article Synopsis
  • Etrasimod is a selective oral drug that has been linked to a potential increased risk of macular edema, a condition affecting the eye.
  • In a clinical study focusing on patients with conditions like ulcerative colitis and Crohn's disease, the rate of macular edema associated with etrasimod was similar to that of a placebo, with very few cases reported.
  • Overall, macular edema and other eye-related issues were rare among patients taking etrasimod, and most related side effects were not serious.

Background: Bowel urgency, the sudden and immediate need to have a bowel movement, is common in patients with ulcerative colitis (UC) and Crohn's disease (CD). While its impact in UC is well established, less is known about its importance in CD. Further, what level of bowel urgency control patients with UC or CD would consider to be acceptable or in remission has not been established.

Background: Small bowel obstructions (SBOs) are a common complication following staged IPAA. Our goal was to compare early post-operative SBO outcomes between different staged ileal pouch-anal anastomosis (IPAA) and to further analyze the type of procedures required in patients who needed operative management of SBO.

Methods: In this retrospective cohort study, we selected all patients who presented to our tertiary care center between 2008 and 2017, with ulcerative colitis or IBD-Unspecified colitis and who underwent a primary total proctocolectomy with IPAA for medically refractory disease or dysplasia (n = 623).

Background: Children with inflammatory bowel disease (IBD) may have diminished serologic response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and increased risk for subsequent severe coronavirus disease 2019 (COVID-19) infection. We sought to describe outcomes among those who developed SARS-CoV-2 infection following vaccination, characterize SARS-CoV-2 antibodies 1 year post-vaccination, and identify factors associated with durable serologic response.

Methods: We recruited children with IBD who received ≥2 doses of SARS-CoV-2 vaccine and prospectively collected data on (1) demographics, IBD characteristics, and therapy and (2) SARS-CoV-2 vaccination, testing, and infection symptoms.

Background: Treatment of inflammatory bowel disease-Crohn's disease (CD) and ulcerative colitis (UC)-is dependent on healthcare providers' (HCPs') clinical assessment of patient symptoms. We therefore evaluated which CD and UC symptoms impact HCPs' treatment choices and assessed the impact of those symptoms on treatment decision-making. We also examined the role of complete control (mucosal/histologic healing, clinical remission, no bowel urgency) in treatment decision-making, considerations for dose escalation or switching treatments, and HCPs' willingness to use the Urgency Numeric Rating Scale (NRS) to assess bowel urgency severity.
