Active clinical trials for "Inflammatory Bowel Diseases"

Inflammatory bowel disease (IBD) is a common chronic inflammatory disorder, but a noninvasive method of assessing disease location, severity, and extent is currently not available. Recently published animal data suggests that using transabdominal ultrasound enhanced with encapsulated gaseous microbubbles may provide a reliable, noninvasive means to detect and quantify areas of intestinal inflammation. This study will evaluate the role of Contrast-enhanced ultrasonography (CEU) for use as a diagnostic tool in patients with IBD. We hypothesize that the severity and extent of chronic intestinal inflammation, as quantified by CEU-derived video intensity scores, will correlate with endoscopically-derived measures of intestinal inflammation as obtained from the Crohn's Disease Endoscopic Inflammatory Index (CDEIS). A total of 40 patients will be enrolled in the study, 30 patients with IBD and 10 patients undergoing colonoscopy for other reasons. Prior to colonoscopy CEU assessment of small and large intestine will be performed to evaluate neoangiogenesis and intestinal blood flow. The correlation between the CEU-derived video intensity score and CDEIS will be assessed using Pearson's correlation coefficient. Subjects may also undergo scoring using the Rutgeerts Score, an endoscopic disease assessment index used to score disease activity in patients with previous ileocolonic resection. Comparing video intensity between IBD and non-IBD subjects will be performed using the Wilcoxon rank sum test, with a secondary aim of establishing preliminary estimates of the sensitivity of the microbubble scoring system.

The aim of this study is to evaluate the treatment of iron deficiency in IBD patients.

Subjects must be 18- 75 years old and have a history of both inflammatory bowels disease (Crohn's or ulcerative colitis) and pyoderma gangrenosum. This is a 6 month open label study of an intravenous (IV) medication. Visits occur every 2 weeks initially, then every 1-2 months later in the study.

Our objective is to determine whether a specific dietary intervention or a fructooligosaccharide (FOS) supplement has anti-oxidant or prebiotic effects and whether it is beneficial in the treatment of Crohn's Disease (CD.

Role of C-Reactive Protein /Albumin Ratio in evaluation of Disease Activity in Patients with Inflammatory Bowel Disease.

Methotrexate is one of the immunosuppressants used in chronic inflammatory bowel disease (IBD). It is indicated as monotherapy for induction and maintenance treatment of Crohn's disease (CD), or in combination with anti-tumor necrosis factor (TNF) agents for prevention of immunization. The main objective is to assess the persistence rate of methotrexate treatment in patients followed for chronic inflammatory bowel disease (IBD).

This is a multicentre, phase IV, prospective, interventional cohort study to evaluate the safety and effectiveness of switching from Originator (Humira®) to Biosimilar (Imraldi®) adalimumab in routine clinical practice. The study will include approximately 170 patients (100 patients treated in OLV Aalst and 70 patients treated in AZ Maria Middelares Gent). The study collects baseline clinical characteristics and assessment of parameters regarding switch and overall satisfaction. For patients who are willing to switch, there is a 12-month follow-up (study) period. During the follow-up (study) period patients will continue their treatment with adalimumab, i.e. Imraldi®, except if good clinical practice for the patient would oblige the treating physician to change treatment regimen.

The inflammatory bowel diseases (IBD) are chronic inflammatory disorders of the gastrointestinal tract that manifests as Crohn's disease (CD) and Ulcerative colitis (UC . Over the last two decades the incidence pattern of UC showed significant increase in previously low incidence areas such as Asia and the Middle East. In addition to microbial and environmental factors influencing IBDs, they are complex genetically, where hundreds of genetic loci contribute to disease susceptibility . Genome-wide association studies (GWAS) have identified several genetic susceptibility loci for UC and CD. Among the genetic factors involved, there are several single nucleotide polymorphisms (SNP) in molecules of the immune system associated with either susceptibility or protective effects to IBD progression, but with contradictory associations, mainly depending on the onset (adult or pediatric), sample size differences, inadequate statistical power and on the ethnicity-dependent genetic background. Growing evidence indicates that (RAGE) is involved in chronic inflammation and cancer. It is a transmembrane receptor normally expressed at low levels on a wide range of cells, bind a broad spectrum of ligands. Activated RAGE induces the synthesis of proinflammatory molecules resulting in magnifying rather than dampening inflammation . The human RAGE gene is located on chromosome 6p21.3, in the so-called class III of the major histocompatibility complex. The SNP at the -374A/T and -429T/C of the promoter region have been shown to increase protein synthesis threefold and twofold, respectively. Few studies found that RAGE is up-regulated in IBD, and it appears to play a role in the mechanisms involved in chronic inflammation Little information is available on the possible association of such polymorphisms with IBD. Few studies was carried out in different countries to assess these polymorphisms in IBD, resulting in conflicting results, between supporting and denial of the association. Due to this discrepancy we aimed to study this gene in our community including IBD patients.

The study aims to evaluate the clinical efficacy and safety of fecal microbiota transplantation by automatic methods in the treatment of moderate to severe active ulcerative colitis. There are two groups according to FMT pathway ( through a naso-jejunal tube or transendoscopic enteral tubing). Patients were followed up until 2 weeks after the final FMT in hospital.

The study is planned as a randomised control trial to study the adjuvant use of antibiotics (ceftriaxone and metronidazole) to achieve a clinical response in hospitalised patients with acute severe ulcerative colitis
