Active clinical trials for "Inflammatory Bowel Diseases"

Infections after elective intestinal surgery remain a significant burden for patients and for the health care system. The cost of treating a single surgical site infection is estimated at approximately $27,000. In adult patients, there is good evidence that the combination of oral antibiotics and mechanical bowel preparation is effective at reducing infections after intestinal surgery. In children, the body of evidence is much weaker. In this population, little evidence exists for oral antibiotics reducing infections and no data exists as to the effect of combining antibiotics with mechanical bowel preparation (such as polyethylene glycol (PEG)). The goal of the proposed study is to examine the effects of oral antibiotics with and without the combined use of mechanical bowel preparation on the rate of post-operative infectious complications in children aged 6 months to 18 years. This will be compared to the institution's current standard of care, which is to abstain from any type of mechanical bowel preparations or oral antibiotic administration before intestinal surgery.

Crohn's disease (CD) is a chronic recurrent intestinal inflammation involving the whole digestive tract, with high disability rate, high surgical rate and high recurrent rate postoperatively. Preventing postoperative recurrence in CD patients is an important clinical problem needed urgent intervention. Azathioprine (AZA) and infliximab (IFX) effectively prevent postoperative recurrence in CD patients, but the postoperative recurrence rate is still as high as 41%. Oral supplement of n-3 polyunsaturated fatty acids (n-3 PUFA) owns the advantages of high compliance and low economic cost. We aim to evaluate the effect of routine treatment (AZA/IFX) combined with long-term dietary n-3PUFA on the prevention and treatment of postoperative recurrence of CD, which help optimize the treatment strategy for the prevention of postoperative recurrence.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a idiopathic, chronic and frequently disabling inflammatory disorder of the intestines characterized by a dysregulated mucosal immune response that affect more than a million Americans. This protocol is aimed at obtaining tissue samples to test for expression of genes associated with IBD and to better understand the pathogenesis of IBD with the study of genetics, proteomics, physiologic processes and microbiomes (microbiology).

This will be a randomized placebo-controlled trial in inflammatory bowel disease patients before initiation of anti-tumor necrosis factor-α (anti-TNF) therapy that aims to test the effect of a pre-treatment short course of azithromycin therapy on immunogenicity

This is a prospective, randomized study to assess the impact of telemedicine (telemonitoring, tele-education and tele-consultation) on the patients with Inflammatory Bowel Disease (IBD). The main study objective is to evaluate the impact of telemedicine on the quality of life in IBD. The secondary study endpoints are to minimize adverse drug reactions, to reduce the number of IBD relapses, to improve medication adherence, to improve satisfaction with medical care, to minimize the use of healthcare resources. It is planned to enroll 60 patients. The study duration is 1 year (6 months - patient enrollment, 6 months - telemedical intervention). The study consists of 3 stages. The first stage is selection of patients with IBD after treatment in the gastroenterology department. The second stage is face-to-face appointment and general recommendations (for the observation group); monthly completion of questionnaires on the web-platform, possibility to contact with doctor via chat or phone call, access to educational information (for the intervention group). The third stage is the evaluation of IBD activity (re-hospitalization after 6 months), psychological well-being, quality of life, medication adherence, etc.

Inflammatory bowel disease ((IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC)), is a chronic, immune-mediated disease characterized by recurrent episodes of relapse. The incidence of IBD is increasing worldwide and poses as a burden that reduces quality of life and has a significant impact on health care resources. The advent of monoclonal antibodies to tumor necrosis factor-α (anti-TNF) has revolutionized treatment of IBD, improving rates of remission and reducing hospitalizations and surgeries. Nevertheless, many patients do not adequately respond to these therapies or lose response over time. Thus, there is an important need for novel immunomodulating agents to improve our ability to achieve remission. Besides its traditional role in bone homeostasis, several studies have recognized the important role Vitamin D plays in modulating the immune response, cancer, and cardiovascular disease. Specifically, Vitamin D may mediate immunity by modulating autophagy in leukocytes and regulating the gut microbiome. Thus, Vitamin D may play an important role in IBD. Furthermore, evidence suggests that the effect of vitamin D may be mediated through the TNF-α pathway, suggesting a synergy with anti-TNF therapy. This is a randomized, double blind, placebo-controlled trial to study the effect of Vitamin D3 as an adjunct therapy for patients with active CD, UC, or IBD unspecified who are undergoing anti-TNF induction therapy.

Inflammatory bowel disease consists of ulcerative colitis (UC) or Crohn's disease (CD). The main aim of this study is to describe real-world data on vedolizumab serum concentration and treatment outcomes in cohort of patients treated at the Department of Gastroenterology and Hepatology of University Hospital Center Osijek. Study will be recruiting patients who switched from intravenous to subcutaneous vedolizumab according to routine clinical practice.

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.

Detection of Volatile Organic Compounds (VOC) directly from tissue by headspace analysis (skin, surgery material, other tissue) and exhaled breath is feasible using affordable user-friendly novel nano-chemo sensors that can accurately be used for screening and monitoring purpose

The goal of the Precision Diagnosis in Inflammatory Bowel Disease, Cellular Therapies, and Transplantation (PREDICT) trial is to apply a systems-biology approach to enable precision diagnostics for the key immunologic outcomes for patients with Inflammatory Bowel Disease, Cellular Therapeutics and Transplantation. This approach will deepen the understanding of the molecular mechanisms driving auto- and allo-immune diseases and serve as a critical platform upon which to design evidence-based treatment paradigms for these patients. This research study will examine the immunology of auto- and allo-immune gastrointestinal disturbances such as Inflammatory Bowel Disease (IBD), Graft-versus-Host Disease (GVHD), and Functional Gastrointestinal Disorder (FGID), as well as the immune manifestations after CAR-T and other cellular therapeutics. The Investigators seek to use blood and tissue samples in order to better understand the mechanisms driving these diseases and their therapies. The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD, GVHD and the response to cellular therapeutics, as well post-transplant defects in protective immunity, and determine which pathways, when perturbed, can cause clinical disease. The discovery of these pathways will lead to improved diagnostic, prognostic and treatment approaches, and to personalized therapeutic decision-making for these patients.
