Background: Infiltration of GI by T lymphocytes is a pathogenic mechanism both in ulcerative colitis (UC) and in Crohn's disease (CD). Vedolizumab (VDZ) is a humanized monoclonal antibody binding with high affinity to α4β7 integrin blocking α4β7+-MAdCAM-1 interaction, hence blocking a key step in GI lymphocytes T infiltration. VDZ has demonstrated a therapeutic effect in UC and CD. Investigators still lack of adequate biomarkers to predict clinical response to biological treatments, specially avoiding invasive procedures. Objective: Study whether circulating CD4+ and CD8+ α4β7+ memory T lymphocytes and some of their surface markers might be molecular markers of response to VDZ treatment in patients with UC and CD. Methods: Prospective (pilot) study including 24 adult IBD patients (12 UC patients and 12 CD patients (patients with fistulizing perianal disease will be excluded) with active disease and prior failure to anti-TNFα treatments starting treatment with VDZ. They will received VDZ in standard induction (300mg intravenously, 0-2-6 weeks) and maintenance schemes (300mg intravenously, every 8 weeks). Epidemiological and clinical data from every patient will be recorded prospectively. Disease activity at weeks 0, 2, 6 and 14 weeks will be evaluated through validated clinical scores, biological parameters and fecal biomarkers. At week 14 response to the treatment will be evaluated by ileocolonoscopy or enteroMRI. Peripheral blood will be obtained from every patient at baseline, before the third infusion of VDZ (6th week) and before the first maintenance dose (14th week). Blood lymphocytes will be isolated and multicolor flow cytometry will be performed on stored circulating memory T cells. Percentage and absolute values of circulating CD4+ and CD8+ α4β7+ memory T lymphocytes as well as several surface markers related to their activation state (HLA-DR, CD25), Th17 phenotype (IL23R, CCR6, intracellular IL17A) and Th1 phenotype (INFγ)will be assessed on α4β7+ memory T cells.
This study seeks to test the feasibility of a self-management manual with minimal telephone support by a healthcare professional. The study will also explore the acceptability of the intervention manual to patients.
Malnutrition and growth retardation are common in children with inflammatory bowel disease (IBD), especially in Crohn's Disease (CD). Malnutrition is associated with disease type, anatomical location, severity of disease and age of patient. Recently, it is reported that almost all children with CD and half with Ulcerative Colitis (UC) have reduced lean mass, however, body fat alteration are not well defined. The aim of this prospective and observational study was to evaluate nutritional and growth status and body composition of children with IBD using anthropometric measurement and bioelectrical impedance during 1 year follow-up.
This is a placebo controlled, cross-over, randomized, double blinded study. The intervention food products will be taken as diet prebiotic supplements: 1. Wheat Bran Extract rich in arabinoxylan oligosaccharides : 15g/d (up to 10 g total additional dietary fibre per day). 2. Placebo product maltodextrin:equal amounts of a digestible carbohydrate. Primary endpoints are faecal microbiota analysis and faecal metabolite analysis (particularly, short chain fatty acid). Secondary endpoint is serum cholesterol, glucose, HDL and bowel function, gastrointestinal tolerance, quality of life and food frequency (by the use of questionnaires).
The purpose of this research study is to improve the understanding of irritable bowel syndrome (IBS) and its underlying cause. The investigators will use magnetic resonance imaging (MRI) to observe differences in the brain between people diagnosed with IBS compared to healthy controls and people with ulcerative colitis, a disease group that has already been characterized. By doing this correlative and comparative study, the investigators hope to gain knowledge on IBS in order to keep the field moving in the right direction and becoming one step closer to discovering effective treatments.
This is a prospective, observational, multicenter, population-based incidence cohort study which will enroll cases of IBD (CD, UC, or indeterminate colitis) diagnosed in adults over 1 year in Spain. In addition, each incident case that gave his/her informed consent, will be followed up for 12 months to determine changes in phenotype or disease location, the need for immunosuppressive and biologic treatments, and the need for hospital admissions and surgery during the first year after diagnosis.
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 determine the safety and tolerability of administration of multiple ascending doses of KHK4083 and to select the highest dose tolerated by subjects with moderately active Ulcerative Colitis (UC) followed by a Long-term Extension Therapy (LTE) phase for eligible subjects with a clinical response.
The investigators are testing the effect of electrical stimulation of the rectum on colonic motility. Most individuals with spinal cord injury develop neurogenic bowel dysfunction, which includes slowed colonic motility, which means that stools take longer than normal to pass through the colon. This slowed movement may result in chronic constipation and difficulty emptying the bowels. Individuals typically (without or without caregiver assistance) insert a gloved finger into the rectum and gently stretch it to improve colonic motility for a brief period to empty the bowels. The investigators hypothesize that electrically stimulating the rectum, instead of mechanically stretching it, will produce the same beneficial effect of improving colonic motility. Therefore, this study will compare the two methods. If electrical stimulation effectively improves colonic motility, then the investigator shall develop the approach as a therapeutic intervention in future studies.
