faecal calprotectin in ulcerative colitis

BACKGROUND AND AIMS: Digital collection of patient reported outcome measures (PROMs) is largely unexplored as a basis for follow up for patients with ulcerative colitis (UC). Our aim was to develop a model to predict the likelihood of escalation of therapy or intervention at an outpatient appointment that may be used to rationalise follow up. METHODS: TrueColours-IBD is web-based, real-time, remote monitoring software that allows longitudinal collection of ePROMs...

BACKGROUND: Birth cohort studies with linked register-based data on inflammatory bowel disease (IBD) provide opportunities to prospectively study early-life determinants of the disease. However, register-based data often lack information on clinical characteristics and rely on diagnostic algorithms. Within the All Babies in Southeast Sweden (ABIS) cohort, we examined the validity of a register-based definition of IBD, its incidence, and clinical and therapeutic characteristics at diagnosis...

BACKGROUND: Real-world data on long-term outcomes of vedolizumab (VDZ) are scarce. OBJECTIVE: To assess long-term outcomes (up to 3 years) of VDZ in treating inflammatory bowel disease (IBD). DESIGN: A nationwide, prospective multicentre extension of a Swedish observational study on VDZ assessing Effectiveness And Healthcare resource utilization in patients with IBD (SVEAH). METHODS: After re-consent, data of patients with Crohn's disease (CD) ( n  = 68) and ulcerative colitis (UC) ( n  = 46) treated with VDZ were prospectively recorded using an electronic case report form integrated with the Swedish IBD Register (SWIBREG)...

Background and aims: Point-of-care tests (POCT) allow instant measurement of inflammatory markers and drug concentrations. Here, we studied agreement between a novel POCT device and reference methods of measuring infliximab (IFX) and adalimumab (ADL) serum concentrations and C-reactive protein (CRP) and faecal calprotectin (FCP) concentrations of patients with inflammatory bowel disease (IBD). Methods: In this single-centre validation study, IBD patients were recruited in which IFX, ADL, CRP and/or FCP tests were required...

BACKGROUND: Curcumin and QingDai (QD, Indigo) have been shown to be effective for treating active ulcerative colitis (UC). AIM: To evaluate the real-world experience with the Curcumin-QingDai (CurQD) herbal combination to induce remission in active UC. METHODS: A retrospec-tive multicentre adult cohort study from five tertiary academic centres (2018-2022). Active UC was defined as a Simple Clinical Colitis Activity Index (SCCAI) ≥ 3...

BACKGROUND AND AIMS: The Milan ultrasound criteria [MUC] is a validated score to assess endoscopic activity in ulcerative colitis [UC]. MUC > 6.2 detects Mayo endoscopic score [MES] > 1. In this study we evaluated the predictive value of MUC for biologic treatment response, using colonoscopy [CS] as a reference standard. METHODS: Consecutive UC patients starting biologic therapy were included, and underwent CS, IUS, clinical assessment and faecal calprotectin [FC] measurement at baseline and within 1 year...

BACKGROUND: Despite advances in ulcerative colitis (UC) therapies, a relatively undefined proportion of patients experience faecal incontinence (FI) in the absence of active inflammation. For this group, there remains a significant unmet need with a limited evidence base. AIMS: We aimed to estimate the prevalence and impact of FI in UC. METHODS: In a prospective cross-sectional study, patients with UC completed a series of validated questionnaires, including Rome IV FI criteria, an inflammatory bowel disease (IBD)-specific FI questionnaire (ICIQ-IBD), Hospital Anxiety and Depression Scale and IBD-Control...

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) remains the preferred surgical option for medically refractory ulcerative colitis. Management of individuals with an IPAA prior to and during pregnancy presents challenges that can have serious consequences. Infertility, mechanical obstructive and inflammatory pouch complications are frequently encountered in pregnant women with an IPAA. Mechanical obstructions occur due to a variety of underlying aetiologies, including stricturing disease, adhesions and pouch twists...

BACKGROUND: Switching from originator infliximab (IFX) to biosimilar IFX is effective and safe. However, data on multiple switching are scarce. The Edinburgh inflammatory bowel disease (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). OBJECTIVE: The primary endpoint of this study was to assess CT-P13 persistence following switch from SB2. Secondary endpoints included persistence stratified by the number of biosimilar switches (single, double and triple), effectiveness and safety...

BACKGROUND AND AIMS: Ulcerative colitis [UC] impacts patients' health-related quality of life [HRQoL]. We assessed HRQoL and an exploratory patient-level composite endpoint ('Comprehensive Disease Control' [CDC]) in individuals receiving filgotinib [an oral JAK1 preferential inhibitor] in the SELECTION trial. METHODS: In SELECTION [NCT02914522], a double-blind, randomized, placebo-controlled, phase 2b/3 trial, adults with moderately to severely active UC received once-daily filgotinib 200 mg, filgotinib 100 mg or placebo for 11 weeks in Induction Study A [biologic-naïve] or B [biologic-experienced]...

BACKGROUND: Endoscopic and histological activity scores in ulcerative colitis (UC) are associated with clinical outcomes and have become important targets of clinical trials. However, these endpoints have been scarcely investigated in patients receiving only conventional treatment. OBJECTIVE: We aimed to assess the deep and complete remission rates after 3 months of conventional treatment in patients with newly diagnosed UC with moderate to severe endoscopic activity...

BACKGROUND: Inflammatory bowel disease (IBD), which is an umbrella term used for ulcerative colitis (UC) and Crohn's disease (CD), is associated with an increased risk for atherosclerotic cardiovascular disease (CVD). We aimed to investigate the association of local and systemic biomarkers of inflammation and gut microbiota-derived metabolite trimethylamine N-oxide (TMAO) with endothelial and coronary microvascular dysfunction in IBD. METHODS: A total of 56 patients with IBD (20 with UC and 36 with CD) and 34 age and gender matched controls were included...

BACKGROUND: There are no data to assess the value associated with a treat-to-target (T2T) strategy based on tight control of mild-moderate ulcerative colitis (UC). AIM: To assess the cost-effectiveness of a T2T approach based on the normalisation of clinical signs and faecal calprotectin (FC) METHODS: A decision analytical Markov model was developed to compare T2T algorithm combining clinical symptoms and FC levels to define treatment response and the possible switch to the next treatment line (T2T-FC), and the reference strategy based only on symptoms...

BACKGROUND: Scarce data are available on the use of vedolizumab in children with inflammatory bowel disease (IBD). We aimed to evaluate the safety, effectiveness, and dosing of vedolizumab to induce remission of IBD. METHODS: VEDOKIDS was a paediatric, multicentre, prospective cohort study done in 17 centres in six countries. We report the 14-week outcomes as the first analyses of the planned 3-year follow-up of the VEDOKIDS cohort. Children (aged 0-18 years) with IBD who had commenced vedolizumab were followed up at baseline and at 2, 6, and 14 weeks...

BACKGROUND: Tofacitinib is an oral Janus kinase (JAK) inhibitor and is registered for the treatment of ulcerative colitis (UC). The effectiveness of tofacitinib has been evaluated up to 12 months of treatment. AIM: The aim of this study was to assess the effectiveness and safety of 24 months of tofacitinib use in UC patients in the Netherlands. METHODS: Patients initiating tofacitinib treatment were included in the ICC Registry, a nationwide, observational registry...

Objective: Ustekinumab is an interleukin-12/interleukin-23 receptor antagonist licensed for the treatment of ulcerative colitis (UC). Clinical trial data were promising; however, real-world data are limited. We assessed the safety and effectiveness of ustekinumab in UC in a real-world setting. Design/method: This was a multicentre, retrospective, observational cohort study between February 2020 and January 2022. Disease activity was assessed using the Simple Clinical Colitis Activity Index (SCCAI)...

Objective: Faecal calprotectin (fCAL) is an established marker of intestinal inflammation in inflammatory bowel disease (IBD). Disproportionally high fCAL levels, for the severity of intestinal inflammation, have been previously observed in primary sclerosing cholangitis associated IBD (PSC-IBD). The aim of this study was to test the hypothesis that fCAL is a marker of biliary injury in PSC-IBD. Methods: We used two cohorts: (1) post hoc analysis of a colonoscopic surveillance study allowing correlation of fCAL to endoscopic severity as measured by the ulcerative colitis endoscopic index of severity (UCEIS) in PSC-IBD (n=20) and ulcerative colitis (UC, n=20) and (2) prospective recruitment of patients attending for endoscopic retrograde cholangiopancreatography allowed the correlation of fCAL to biliary calprotectin (n=8)...

BACKGROUND: The Inflammatory Bowel Disease Symptom Inventory (IBDSI) is a validated patient self-reported measure used to assess IBD disease activity. There has yet to be more granular analyses on which symptoms are most associated with active disease. AIMS: To assess the prevalence of symptoms, and examine which symptoms are most associated with disease activity as measured by a symptom index and objective measure of inflammation. METHODS: The Manitoba Living with IBD Study is a prospective study of 156 participants with confirmed IBD who completed bi-weekly IBDSI...

BACKGROUND AND AIMS: To advance the understanding of inflammatory bowel disease [IBD] pathophysiology, we compared the mucosal and plasma metabolomes between new-onset paediatric IBD patients and symptomatic non-IBD controls, and correlated plasma inflammation markers and disease characteristics with the altered metabolites. METHODS: Paired colonic and ileal biopsies and plasma from 67 treatment-naïve children with incident Crohn's disease [CD; n = 47], ulcerative colitis [UC; n = 9], and non-IBD controls [n = 11] were analysed using ultra-performance liquid chromatography-mass spectrometry [UPLC-MS/MS]...

BACKGROUND AND AIMS: The utility of real-world data is dependent on the quality and homogeneity of reporting. We aimed to develop a core outcome set for real-world studies in adult patients with inflammatory bowel disease (IBD). METHODS: Candidate outcomes and outcome measures were identified and categorised in a systematic review. An international panel including patients, dietitians, epidemiologists, gastroenterologists, nurses, pathologists, radiologists and surgeons participated in a modified Delphi consensus process...
