Filter by:The investigators propose the use of a 20 week physician-derived exercise programme will lead to an improvement in physical fitness which will in turn lead to an increase in muscle mass, a reduction in visceral obesity resulting in an improvement in biologic response, disease biomarkers (including a reduction in circulating pro-inflammatory cytokines), fatigue scores and quality of life.
Researchers want to understand if a combination of usual medical care along with a wellness program designed for women with Inflammatory Bowel Disease diagnosis will have an effect on quality of life, stress, and disease activity.
The inflammatory bowel diseases (IBD) are lifelong, relapsing-remitting diseases. As the timing of relapse is unpredictable, and current monitoring is symptoms-based, there remains a window between the initial upregulation of the inflammatory response and the onset of clinical symptoms at which point the inflammatory episode is well established. The use of endoscopy as means of predicting relapse is not suitable for regular use. The potential role of Fecal calprotectin (FC) in IBD in predicating the risk of relapse has been well investigated with key studies. Its fecal concentration is proportional to neutrophilic influx into the intestinal tract, which is a feature of active IBD. FC correlates well with the severity of endoscopic lesions. After excretion, FC remains stable in the feces for 1 week at room temperature. However, its considerable daily variation suggests interfering factors discrete from inflammatory disease. There is increasing research into novel markers with high correlation to the presence of mucosal healing constitute a cost-effective substitute to repeated endoscopies. Recent studies have reported that the prostaglandin E-major urinary metabolite (PGE-MUM) level was significantly higher in the active phase of patients with ulcerative disease (UC) than those in the remission phase. In the active UC phase, the stimulation of inflammatory cytokines, such as tumor necrosis factor-α, leads to the upregulation of cyclooxygenase-2 (COX-2) leading to PGE2 secretion in mucosal tissue. PGE2 plays an important role in the progression of inflammation. A precise measure of serum PGE2 is difficult due to the short half-life of PGE2 in the blood. Conversely, the urinary metabolite of prostaglandin E-major (PGE-MUM, 7-hydroxy-5,11-diketotetranor-prosta-1,16-dioic acid) is stable and may reflects the histological severity of inflammation. The aim of this concept study is to evaluate the PGE-MUM concentration in urine of patients with IBD in parallel with the standard investigation of Calprotectin in stool and to assess if urinary PGE-MUM should be able to serve as a simple and robust substitutive biomarker for the non-invasive evaluation of the inflammation of the mucous membrane tissues. The measurement of PGE-MUM in urine could give patients with IBD more comfort than the measurement of calprotectin in stool.
Inflammatory bowel disease (IBD) is considered a risk factor for the development of osteoporosis, which leads to an increased risk of fractures. There is no data on bone quality obtained with imaging techniques other than bone densitometry such as Trabecular Bone Score (TBS), 3D bone densitometry (DXA-3D) or quantitative bone ultrasound (QUS). The TBS study can provide information on bone microarchitecture in these patients, with TBS values expected to be lower than those of subjects without IBD, with a decrease of up to 50 points in this parameter. Primary objective: to evaluate and compare TBS values in patients with IBD and in a control group of volunteers without IBD or known metabolic bone pathology, adjusted for age, sex and body mass index (BMI). Secondary objectives: to evaluate and compare results in DEXA parameters, QUS, DEXA-3D, biochemical parameters and FRAX data between patients with IBD and controls. To evaluate the prevalence of vertebral fractures analyzed by VFA. As well as to evaluate the evolution in one year of all these parameters in patients with IBD. Prospective observational study with a cohort of patients with IBD and another of volunteers without IBD or metabolic bone pathology, adjusted for age, sex and BMI. Baseline bone quality data will be analyzed by bone densitometry, TBS, DEXA-3D and QUS, fractures assessed by VFA and bone remodeling markers in both cohorts. Subsequently, a one-year analysis of the parameters of the IBD cohort will be performed.
This study will investigate the correlation of fecal calprotectin (FC) values to quiescent ulcerative colitis and to disease activity (relapse) as assessed by clinical data and endoscopy.
The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.
Inflammatory activities in the gastrointestinal tract are accompanied by an increase in blood flow in the intestinal wall layers of the respective organs. Also in chronic inflammatory bowel diseases, the release of vasoactive inflammatory mediators leads to vasodilation and consecutive increase of blood flow in the bowel wall. So far, these changes in blood flow can be detected by power Doppler sonography without being part of routine clinical diagnostics. Another promising option for non-invasive measurement of blood flow in the intestinal wall is Multispectral Optoacoustic Tomography (MSOT). Previous studies have shown that MSOT can be used to quantitatively measure hemoglobin in the bowel wall and thus provide information on blood flow and inflammatory activity in the intestines of patients with Crohn's disease. This is currently being further investigated in a pivotal study (Euphoria, H2020) and could lead to the possibility of non-invasive assessment of disease activity in inflammatory bowel disease (IBD) in the future. The regional blood flow in the intestinal wall and the distribution of gastrointestinal blood flow are also subject to strong postprandial changes. During absorption of food components, blood flow increases sequentially in the respective sections of the gastrointestinal tract, leading to postprandial hyperemia. Because postprandial hyperemia is particularly regulated locally by the presence of dietary components, there is a relationship between the sequential increase in blood flow in the intestinal wall and the peristaltic transport of chyme through the gastrointestinal tract. Postprandial hyperemia could also lead to an increase in the optoacoustic hemoglobin signal of the intestinal wall and thus have an impact on the assessment of inflammatory activity in IBD using MSOT. Additionally, MSOT allows the identification of non-absorbable exogenous chromophores, such as indocyanine green (ICG), which could allow co-localization of the chyme in the intestinal lumen after oral application of ICG. This pilot study investigates whether postprandial blood flow changes can be quantitatively measured using MSOT and whether these changes occur simultaneously with the gastrointestinal passage of the chyme as measured by the ICG signal in the intestinal lumen.
Descriptive : A 12-months multicenter, observational, prospective cohort study. Population : IBD patients under stable clinical and biological remission will be proposed to switch from the IV vedolizumab to the SC vedolizumab as part of routine care. All consecutive IBD patients in IBD centers participating in the study will be proposed to participate in the study during their regular outpatients' visits. Objectives : The primary objective of DOPER study is to describe SC vedolizumab persistence after switching from IV vedolizumab to SC vedolizumab at month 12.
Within this study, the investigators aim to directly compare the value of endoscopic remission, histologic remission and barrier healing for predicting long-term disease behavior in a large cohort of clinically remittent IBD patients.
Ulcerative colitis (UC) and Crohns disease (CD) represent the two major forms of inflammatory bowel disease (IBD), characterized by epithelial cell damage and prominent mucosal infiltration by inflammatory cells including granulocytes, macrophages, lymphocytes, and plasma cells.
