Filter by:The management of anal fistula in Crohn Disease is complex. In aim to obtain the healing of the anal fistula, different approaches can be proposed but the best strategy is not yet determined. The aim was to describe the therapeutic management of anal fistula in Crohn Disease.
The current available therapies for inflammatory bowel disease (IBD), including immunomodulator and biologic medications may have toxicities limiting use or inadequate effect. We propose a novel approach to the treatment of IBD by using transcutaneous vagal nerve stimulation (VNS). Research has previously identified that VNS using a surgically implanted stimulator can improve symptoms and decrease inflammation in people with inflammatory diseases. This study will evaluate the use of non-invasive nerve stimulation through the skin (rather than through an implanted device) as a potential therapy in pediatric patients with Crohn Disease or ulcerative colitis. We will be evaluating how this nerve stimulation affects symptoms, markers of inflammation found in the blood and stool including cytokine levels, and heart rate variability. The primary hypothesis of the study is the use of transcutaneous VNS will decrease inflammation in people with IBD leading to improved signs and symptoms of disease. The primary endpoint of the study is to evaluate the change in fecal calprotectin after 16 weeks of nerve stimulation. Secondary endpoints include changes in symptom scores, blood cytokine levels, and heart rate variability.
The MELODY Trial: Modulating Early Life Microbiome through Dietary Intervention in Crohn's Disease, will test whether a non-invasive dietary intervention during pregnancy can improve the gut microbiota composition in both pregnant Crohn's disease patients and their babies during the sensitive time window of infant immune system development, and whether this can lead to decreased risk of maternal disease relapse postpartum and decreased functional gastrointestinal disorders and gut inflammation in their babies. Through this trial, the study team hopes to better understand the origin of the initial gut bacterial colonization in babies, providing potential intervention targets to prevent Crohn's disease development in high risk individuals.
For patients with Crohn's diseases，whether prophylactic abdominal drainage is necessary need further exploration. the present study is focusing on the necessity of prophylactic abdominal drainage in CD patients after surgery.
Inflammatory bowel disease (IBD) is a chronic inflammatory state of the gastrointestinal tract(1) affecting 1.6-3.1 million people in the United States. Patients with IBD are treated with immunosuppressants that increase their risk of herpes zoster (HZ), also known as shingles. Those with IBD have a two-fold increased risk for HZ compared to age matched controls. Because most IBD patients are treated with systemic immunosuppressants, which are an independent risk factor for HZ, the live attenuated HZ vaccine was not recommended. However, the release of the new inactivated HZ vaccine, Shingrix (GlaxoSmithKline), presents new opportunities for preventive care.
This study will randomize all patients who are new to the Mayo Clinic HPN team to either standard lipid emulsion (Intralipid) or SMOFLipid.
Crohn's disease affects 200,000 people in the UK (~1 in 500), most are young (diagnosed < 35 years) with costs of direct medical care exceeding £500 million. Crohn's disease is caused by an auto-immune response and affects any part of the digestive tract, most commonly the last segment of the small bowel (the terminal ileum). Magnetic resonance imaging (MRI) plays a role in 3 areas: Crohn's disease diagnosis , monitoring treatment response & assessing development of complications. To evaluate the small bowel using MRI, Radiologists visually examine the scan slice-by-slice. The interpretation is time consuming and error-prone because of disease presentation variability and differentiation of diseased segments from collapsed segments. Deep learning for image analysis is based on a computer algorithm "learning" from human (Radiologist) generated training data. This method has been successfully applied to medical imaging, for example computer detection of lung cancer on chest X-rays. This pilot study investigates if a deep learning algorithm can identify and score segments of inflamed terminal ileum affected by Crohn's disease. To our knowledge this is the first project attempting to develop such an algorithm.The study will retrospectively review MR images obtained as part of standard care from patients being investigated for, Crohn's or being followed up with Crohn's disease. 226 patients' images will be used for the study. On fully anonymised images two Radiologists working at Northwick Park Hospital will score and outline normal and abnormal loops of terminal ileum. Imperial College computer science department will then develop a deep learning algorithm from imaging features of normal and abnormal loops. The study end-point is algorithm performance vs. images labelled by Radiologists. The eventual aim is to develop an algorithm that assists Radiologists in the accurate diagnosis and follow-up of patients with Crohn's disease.
The investigators plan to compare contrast-enhanced ultrasound to CT and MRI for the detection and quantification of intestinal inflammation in the the setting of pediatric small bowel Crohns disease
Crohn's disease (CD) is a chronic inflammatory disease in the gastrointestinal (GI) tract. It is characterized by an alternating course between remission and relapse, which necessitates subsequent adjustments in medical therapy. Thus, it is important to have suitable tools to assess disease activity, and currently the reference standard is using ileocolonoscopy. However, ileocolonoscopy causes major patient discomfort and due to logistic reasons, it cannot be performed on a regular basis. High frequency ultrasound (US) is a potentially useful tool to evaluate changes in disease activity in affected bowel segments. Although there are some studies using US in CD patients to construct ultrasonographic scoring systems, there are no validated scores in daily clinical practice. In a recent study by Nylund et al, we used multiple linear regression to select which simple conventional ultrasound parameters that should be included in an ultrasound scoring system (Simple Ultrasound Score of Crohn's Disease (SUS-CD)) using endoscopy as a reference (unpublished data). In this study, we aim to validate this scoring system using an endoscopic score (Simple endoscopic activity score for Crohn's disease (SES-CD)) as reference standard and to assess interobserver variability. The scoring system might be a useful supplement to endoscopy to follow up CD patients.
The purpose of this study is to evaluate the clinical efficacy (GALAXI 1), clinical and endoscopic efficacy (GALAXI 2 and GALAXI 3) and safety of guselkumab in participants with Crohn's disease.
