Active clinical trials for "Intestinal Diseases"

The purpose of this study is to confirm the sensitivity and specificity of the BÜHLMANN fCAL™ ELISA as an aid in diagnosis to differentiate between Inflammatory Bowel Disease (IBD; Crohn's Disease (CD), Ulcerative Colitis (UC), or indeterminate colitis) and Irritable Bowel Syndrome (IBS). To estimate the predictive value of a positive test (positive predictive value (PPV)) and the predictive value of a negative test (Negative Predictive Value (NPV)) using the proposed test outcomes for BÜHLMANN Calprotectin Test results when used in patients referred for diagnostic evaluation with signs and symptoms suggestive of either IBS or IBD. To confirm the inter-laboratory consistency of test results for the BÜHLMANN fCAL™ ELISA. To provide exploratory observations of test results in patients between the age of 2 and 21 years. To provide a sample set from normal subjects with no symptoms or signs of gastrointestinal disease for use in Expected Value Testing.

Background: The immunologic response to stress is regulated by the cytokines. Anti-Tumor Necrosis Factor-α agents are antibodies directed against a key cytokine in the process angiogenesis and collagen synthesis. It is not known whether they intervene with surgical stress response increasing the rate of postoperative complications. Method: Un-blinded prospective, non-interventional cohort single centre study including all the patients with Crohn's disease and Ulcerative Colitis undergoing abdominal surgery. Immunological and endocrinological parameters will measured in blood samples taken from these patients before and after surgery. Power calculations showed that 17 patients in each arm are needed.

Significance: Biopsy of potentially benign pseudopolyps and the surrounding mucosa adds expense and prolongs the time of endoscopic procedures. Use of endoscopic technologies could decrease the need and expense of endoscopic biopsy for these lesions. Hypothesis: Pseudopolyps will have a distinctive pattern with the specialized imaging techniques of high definition imaging, narrow band imaging, and endoscopic dye-spraying techniques using indigo carmine which will predict diagnosis without biopsy. 100 patients with inflammatory bowel disease will be enrolled in the study. Following a standard bowel preparation, each patient will be evaluated using standard endoscopic equipment. All patients will receive a standard bowel preparation (sodium phosphate, PEG-3350, or magnesium citrate based preparations). All colonoscopic evaluations will be performed for indications unrelated to the present study, including evaluation of response to medical treatment, routine surveillance exams for dysplasia, diarrhea, or rectal bleeding. Polypoid lesions will be examined using four consecutive methods: (a) high definition white light, (b) narrow band imaging, (c) chromoendoscopy (high definition white light with indigo carmine dye-spraying), and (d) histologic examination following biopsy. The flat mucosa surrounding the polypoid lesions will also be examined using theses four techniques in an effort to identify dysplastic tissue associated with these polypoid growths. High definition white light is the standard imaging modality used for colonoscopy. Narrow band imaging (blue wavelength of light) is also used routinely and is available on all current generation colonoscopes with the press of a button. Our division routinely uses chromoendoscopy as part of surveillance for dysplasia in patients with inflammatory bowel disease. Dye spraying catheters or flushing will be utilized for dye application to mucosa. The dye used will be indigo carmine. Directed biopsy specimens will then be performed using a multibite forceps for targeted biopsies. Routine biopsies will be performed as clinically indicated. Pathology slides will be reviewed by the gastrointestinal pathologists at the University of Miami. The gastroenterologist's interpretation based on each of the three successive endoscopic methods will then be compared to the histologic evaluation with each individual lesion serving as its own control.

The purpose of this study is to evaluate the percentage of moderate to severe IBD participants with active disease at Day 1.

The goal of the proposed study is to assess the prevalence of intestinal parasitic diseases in adults and children. These invasions are included to "dirty hand diseases" (per os invasions), therefore it applies mainly preschool children.

The purpose of this study is to evaluate the development of anti-drug antibody to biosimilar CT-P13 and to assess the change of drug concentration for 1 year in patients with moderately to severe inflammatory bowel disease.

The purpose of this study is to characterize the treatment patterns associated with biologics agents use or non-biological therapy in participants with moderate to severe Ulcerative Colitis (UC) and Crohn's Disease (CD).

An ileostomy is a surgical opening established by bringing the end or a loop of the ileum to discharge directly outside the body. This is typically done when part or the entire colon is removed because of IBD, cancer, or familial adenomatous polyposis. Reversal of this procedure, an ileostomy closure, may be done if possible. Ileostomy closure involves reconnecting the ileum to the remaining colon, allowing normal bowel movements again. This study will look at the outcomes of these surgeries in patients who were seen and operated on by the investigators.

To find out what adaptations have been made by Inflammatory bowel disease physicians and patients in relation to therapies in flaring IBD patients during severe acute respiratory syndrome 2-COV and what the impact of these is on IBD patients with no symptomatic COVID-19 and in suspected/confirmed COVID-19. Also whether there any IBD related factors impacting the outcome of patients with COVID-19 symptoms or COVID-19 disease
