Active clinical trials for "Intestinal Diseases"

Summary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.

This study will measure Prostate Specific Antigen (PSA) values in men with Inflammatory Bowel Disease (IBD) before, during, and following a flare. In addition, the effect of any PSA increase will be analyzed and correlated to the location of disease (rectal vs. other). Study findings may help men with IBD by identifying pitfalls in prostate cancer screening for this population and help to stratify and understand the effect IBD has on the prostatic milieu. By optimizing how men with IBD are screened for prostate cancer, future unnecessary healthcare encounters and expenditures may be reduced for this patient group.

Muscle and physical activity play an important role in in growth, development and bone health in healthy children, especially during puberty. Children with inflammatory bowel disease (IBD) have lower level and intensity of physical compared to a control group. Several studies have shown that children with IBD have a lower bone mineral density (BMD) than general population, due to risk factors such as corticosteroid use, disease intensity, inflammation, malnutrition and a vitamin D deficiency. This low BMD is associated with an increased risk of fracture. A recent observational study found a positive and significant correlation between BMD in IBD patients and time spent in moderate to vigorous physical activity for one week (unpublished data).The present study aims to show a benefit of an adapted physical activity program on BMD in children and adolescents with IBD.

Rationale: Acute intestinal ischemia is a life-threatening condition with a short-term mortality that can range up to 80%. Medical diagnosis and treatment have remained troublesome, due to the clinical presentation which is mostly characterized by non-specific signs and symptoms. Early unambiguous diagnosis of acute intestinal ischemia is critical to prevent progression from reversible to irreversible intestinal injury, and henceforth decrease morbidity and improve survival. Objective: We aim to validate a panel of plasma biomarkers and investigate volatile biomarkers that allow early and accurate identification of acute intestinal ischemia in patients. In addition, we aim to identify a volatile organic compound (VOC) profile specific for acute intestinal ischemia in exhaled breath. Study design: Prospective observational study Study population: All patients suspected of acute intestinal ischemia Main study parameters: The primary endpoint of the study is the early and accurate identification of presence and severity of acute intestinal ischemia in patients. The main study parameters are plasma biomarkers indicative for intestinal damage and volatile organic compounds (VOC) in exhaled air of patients suspected of acute intestinal ischemia. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is a minimal amount of risks involved in participating in this study. Blood samples will be obtained with the use of an arterial line, intravenous line (IV), central venous catheter (CVC), peripheral venous catheter (PVC) or a venepuncture. The risk of venepuncture is a small local hematoma. In addition to blood sampling, we will also obtain exhaled air. This non-invasive procedure takes approximately 5 minutes in which patients breath in a 3L Tedlar bag at a normal frequency and volume. This procedure will not cause any physical strain. Collection of samples and data will take place during the hospital stay of the included patients. For this reason, no additional hospital visits are required for this study. Participating patients in this study will have no direct benefits, but in the future the results of our study will likely be useful in the early diagnosis of patients suspected of acute intestinal ischemia. The research goal in this study is the early identification of patients that suffer from acute intestinal ischemia. These patients are difficult to diagnose due to a multitude of non-specific symptoms and the lack of fast and specific tests. In this study we will be able to investigate patients that are admitted with acute abdominal complications and observe them in the early stages of their condition. Accordingly, we will be able to evaluate the proposed panel of biomarkers and to identify VOC patterns in patients with acute abdominal complications.

This is a study of immune responses after eating gluten powder in people with celiac disease and healthy controls.

This study is therefore postulated as a clear alternative that evaluates patients´quality of life, and recognises fecal calprotectin as an inflammatory marker. Longitudinal, prospective, multi-center cohort study to measure the impact that the therapeutic attitude (treatment intensification/de-intensification o escalation/de-escalation) has on the quality of life of patients with UC given a colonoscopy revealing mucosal healing (Mayo 0, Mayo 1); considering as treatment intensification/de-intensification a dose increase or decrease on the same line of treatment, and escalation/de-escalation if there is a change to a new line of treatment.

The aim of the present study is to retrospectively record all the successful pregnancies in Greek IBD patients within the last 10 years and prospectively record all the future pregnancies for the next 4 years. Data will be obtained regarding IBD clinical parameters, before, during and after the pregnancy, pregnancy outcomes, delivery mode, lactation and health status of the offspring. Moreover, the management of the pregnant IBD patients in Greece will be analyzed and compared to the European guidelines, in an effort to develop a position statement applicable to the Greek NHS.

In patients with inflammatory bowel diseases (IBD), characterized by relapsing intestinal inflammation, chronic fatigue is a burdensome and highly prevalent symptom. The aetiology is thought to be multifactorial, including complex interactions of psychological and physical factors such as immunological profiles and gut microbiota. Unfortunately, specific treatment strategies are currently lacking. Since fatigued patients have an impaired physical fitness and are less physically active than patients without fatigue, it is hypothesised that physical exercise might be an effective complementary treatment for patients with IBD suffering from fatigue. During a previous pilot cohort study, significant improvements in fatigue complaints and quality of life were observed following a personalised and intensive exercise program. In this study, a multicenter randomized controlled trial will be performed to further investigate this assumed beneficial effect of intensive physical exercise.

The study participant is being asked to take part in this clinical trial, a type of research study, because the participant has Gastrointestinal (GI) symptoms following a Hematopoietic Cell Transplant (HCT). Primary Objective To determine the safety and feasibility of FMT for treating a GvHD of the gut following HCT. To determine the safety and feasibility of FMT for treating HCT induced gut dysfunction. Secondary Objectives To assess the potential efficacy of FMT for treating a GvHD of the gut following HCT. To assess the potential efficacy of FMT for treating HCT induced gut dysfunction.

The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.
