Filter by: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 Recent unpublished data from Dr.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.
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 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.
Monocentric, prospective interventional study to assess the degree of disease activity with a multispectral optoacoustic tomography (MSOT) handheld scanner in patients with Crohn's disease or ulcerative colitis.
The purpose of this is to formally assess health literacy and medication adherence in participants with Inflammatory bowel disease (IBD). The study also aims to improve medication adherence, health-related quality of life, and disease activity through a 24-week intervention.
Crohn's disease is a chronic inflammatory condition of the intestines that causes abdominal pain, diarrhea, tunnels around the anus (fistulas), and extraintestinal symptoms. Effective medical treatments exist to treat the disease; however they can have significant side effects. Previous studies have shown that sexual function is impaired in patients with Crohn's disease. It is likely that both the symptoms related to the disease, medications used to treat the disease, and surgery all impair sexual function in a variety of ways. For example, body image may be impaired, patients may be worried about bowel incontinence or unpleasant odors associated with diarrhea, patients may have significant pelvic pain secondary to perianal fistulas, or they may have painful intercourse from adjacent inflammation or scarring in the pelvis. The impact of medical treatment on patient's ability to regain sexual function is not known. The investigators propose a 6 month study to compare sexual function before and after treatment in patients with Crohn's disease about to initiate therapy with an anti-TNF drug for treatment of perianal fistula or intestinal Crohn's or about to initiate therapy with steroids. The investigators anticipate that the investigators will show that therapy with an anti TNF agent will result in a more rapid and greater return of sexual function than steroids. This information will be important to help counsel patients about the optimal treatment to begin for treatment of their Crohn's disease. Furthermore, it would be the first study to evaluate the impact of medical therapy on sexual function.
This is a randomized, double-blind placebo-controlled trial of high dose vitamin D3 at 10,000 International Units (IU) daily compared to low dose at 1000 IU daily in patients with Crohn's disease in remission.
