Aconitate decarboxylase 1 (ACOD1; also known as IRG-1) is the ubiquitous source of the metabolite itaconate, which dampens inflammasome activation by preventing HIF1α production of IL-1β and prevents TNF production through NRF2 activation…

BACKGROUND: After successful induction, a subset of patients with Crohn’s disease (CD) experience a secondary loss of response (LoR) to ustekinumab (UST) maintenance therapy. Dose intensification may assist in regaining response…

BACKGROUND: Anti-granulocyte macrophage-colony stimulating factor autoantibodies (anti-GM-CSF) have been associated with development of Crohn’s disease (CD) and complications at time of diagnosis. There are limited data on anti-GM-CSF as a prognostic biomarker in CD…

Switching from originator to biosimilar infliximab (IFX) is effective and safe. However, data on multiple switching are scarce. The Edinburgh IBD unit has undertaken three switch programmes: (1) Remicade to CT-P13 (2016), (2) CT-P13 to SB2 (2020), and (3) SB2 to CT-P13 (2021)…

BACKGROUND: Gut dysbiosis is associated with persistent multi-system symptoms following SARS-CoV-2 infection, or post-acute COVID-19 syndrome (PACS). We performed a randomised controlled trial to assess the effects of gut microbiome modulation on alleviation of PACS symptoms…

The Phase 3 QUASAR Maintenance Study (NCT04033445) is a randomized-withdrawal, double-blind, placebo(PBO)-controlled, study that evaluated the efficacy and safety of maintenance treatment with subcutaneous (SC) guselkumab (GUS), an IL-23p19 subunit antagonist, in patients (pts) with moderately to s…

BACKGROUND: The primary objective of the VIVID-1 trial (NCT03926130) was to demonstrate efficacy and safety of mirikizumab (miri), a p19-directed anti-IL-23 antibody, compared to placebo (PBO) in patients (pts) with moderate-to-severe Crohn’s disease…

BACKGROUND: VTX002 is a novel oral selective sphingosine-1-phosphate-1 (S1P1) receptor modulator in development for the treatment of ulcerative colitis (UC)…

Obefazimod is an investigational, oral, once-daily, small molecule which enhances expression of microRNA-124 and is currently in phase 3 clinical trials for the treatment of patients with moderately to severely active ulcerative colitis (UC) [1]…

Background: Inflammatory bowel disease (IBD) monitoring currently relies on patient reported symptoms or cross-sectional assessments of blood, stool, imaging or endoscopy. Advances in wearable technology provide a novel means to monitor IBD activity in real time, remotely and passively…

Background: Inflammatory bowel disease (IBD) flares occur frequently and are typically assessed by biomarkers in the blood or stool or by imaging or endoscopy after a patient presents with symptoms…
