Filter by:The IBSEN III study will investigate the incidence of inflammatory bowel disease in South Eastern Norway and describe the clinical course of the disease. The investigators will map newly diagnosed and treatment naive IBD patients at various levels (epidemiological, clinical, psychosocial and nutritional as well as immunological, genetic, epigenetic and microbial) as a basis to improve targeted and individualized treatment and care. The investigators will include incident IBD patients at all local- and university hospitals in the South Eastern Health Region in 2016-2018 and follow-up prospectively for five years. The investigators will use standardized and validated registration methods allowing comparability with previous national and international IBD cohorts, link data to national health registries and collect blood, feces and biopsies for bio banking.
In patients with Crohn's Disease, symptoms of inflammatory back pain (IBP) precede changes on plain X-rays by years, and MRI changes of axial inflammation precede development of X-ray changes. Sacroiliitis on MRI without x-ray changes (i.e.Non radiographic SpA) is a valid diagnostic criterion for Spondyloarthritis (SpA) and leads to earlier diagnosis of SpA in patients with IBP. It is unclear when MRI changes occur, and if they precede clinical symptoms of IBP. There are reports of asymptomatic sacroiliitis noted on MRI in Crohn's patients. This is important, as MRI evidence of inflammation may be the first sign of incipient SpA. Inflammation in other regions of the axial skeleton in SpA patients has also been documented, but its significance is unknown. The prospect of undiagnosed and untreated inflammation is concerning, as it can lead to significant morbidity. Moreover, relationship between MRI evidence of axial inflammation-likely a proxy for systemic inflammation- and patient reported outcomes (e.g. ASDAS-CRP= Ankylosing Spondylitis Disease Activity Score- C reactive protein, BASDAI= Bath Ankylosing Spondylitis Disease Activity Index, SF-12 = Short Form- 12, HBI= Hervey Bradshaw Index and PROMIS-29= Patient Reported Outcome Measurement Information System-29), has not been reported. Recent unpublished data from Dr. Longman's lab (collaborator) suggest a distinct intestinal dysbiosis in Crohn's associated SpA. But relationship between this microbiome and MRI changes is yet to be determined. Identifying inflammation earlier on MRI- in the absence of clinical symptoms will provide an opportunity to intervene early with available therapies, such as- biologics etc. Asymptomatic MRI changes could be a marker of underlying systemic inflammation- which is a risk factor for poor outcomes in Crohn's associated SpA. Studying association between whole spine MRI changes with patient reported outcomes) may facilitate informed clinical decision making to initiate targeted therapy to prevent progression of structural damage. Understanding microbial dysregulation in this population, and correlation with MRI changes, could lead to development of therapy targeted to restore intestinal symbiosis.
Up to two hundred un-identified PillCam SB movies will be collected from 2 clinical sites, during up to 3 years and transferred to Given Imaging. Demographical data and medical history will be collected. Capsule transit time in the different sections of the GI will be evaluated.
The purpose of this study is to assess the safety and tolerability of Bacteroides thetaiotaomicron (Thetanix®)) capsules in young people aged 16 to 18 years with stable Crohn's disease.
The purpose of this study is to compare the efficacy of ferric maltol and intravenous iron (IVI) Ferric Carboxy Maltose in the treatment of iron deficiency anaemia (IDA) and subsequent maintenance of haemoglobin in subjects with Inflammatory Bowel Disease (IBD).
The purpose of this study is to assess the prevalence of major structural birth defects in infants of female participants with ulcerative colitis (UC) or Crohn's disease (CD) exposed to vedolizumab during pregnancy, compared to participants with UC or CD exposed to other biologic agents.
The purpose of this study is to assess the long-term safety of vedolizumab versus other biologic agents in participants with Ulcerative Colitis (UC) or Crohn's Disease (CD).
This multi-centre open label study will involve a minimum of 260 patients in 2 cohorts: 86 patients with 'early CD' defined as disease duration < 24 months and no other treatments than corticosteroids and/or thiopurines and 174 patients with 'late CD' defined as active disease despite treatment with immunosuppressives and anti-TNF. Patients with intolerance to IS and anti-TNF will also be allowed in the latter group. Participants will be treated with 12 months of open label vedolizumab (study medication followed by commercial medication once reimbursement is available) and undergo monitoring of endoscopic, histological and clinical disease parameters. No randomization or blinding will be performed but the study management will ensure that recruitment in either study group is comparable for number and profile of patients (on/off steroids).
The purpose of this study is to evaluate the percentage of participants with perianal fistula healing at Week 30 in 2 different dose regimens of vedolizumab intravenous (IV) 300 milligram (mg) in participants with fistulizing Crohn's disease (CD).
Aims: - To study the feasibility of capsule colonoscopy in patients with Crohn's Disease (CD). - To compare the results of capsule colonoscopy with conventional colonoscopy in assessing mucosal healing. - To correlate the level of faecal calprotectin with the results of capsule colonoscopy and conventional colonoscopy. - To document changes in clinical practice attributable to the capsule colonoscopy findings a) concordant with and b) in addition to the parallel findings at colonoscopy and ileoscopy. Project design: Cross sectional, prospective, comparative study Methodology: Patients of the Royal Melbourne Hospital (RMH) and other associated speciality clinics with an established diagnosis of CD who need assessment of mucosal healing and have consented to be part of the study will undergo capsule colonoscopy and conventional colonoscopy on the same day after undergoing bowel preparation. The images of both the conventional and capsule colonoscopies will be recorded. In addition calprotectin (an inflammatory marker in faeces) will be measured in a sample of faeces collected by the patients prior to the colonoscopy day. Professor Macrae and the scholarly selective student researcher will assess the recorded images obtained from capsule colonoscopies once the images have been deidentified. To assess the level of mucosal disease they will use the Simple Endoscopic Score for CD (SESCD). The results of the assessment of mucosal healing obtained from conventional colonoscopy will be compared with those of capsule colonoscopy and levels of faecal calprotectin will then be correlated.
