Active clinical trials for "Ulcer"

This study is designed to evaluate the ability of Spatial Frequency Domain Imaging (SFDI) to measure perfusion in lower extremities for prediction of both healing and formation of diabetic foot ulcers. The investigators will perform longitudinal imaging (for 12 months) in two cohorts of subjects

The study is a randomised controlled trial of patients admitted for a scheduled cardiac surgery at the Clermont-Ferrand hospital. Patients meeting the study inclusion criteria will be allocated to either the control group that will receive pressure ulcer prevention standard care or the intervention group that will receive pressure ulcer prevention standard care plus have a Mepilex® Border dressing applied to their sacrum.

Acute severe ulcerative colitis [ASUC] patients have high risk of no response to medical treatments and might miss the best timing for surgery when waiting for the medical response. Thus, we investigated whether biomarkers which could early predict the surgery risk of patients with ASUC on admission.

The primary objective is to obtain stool samples from post-therapy subjects already undergoing evaluation for an H. pylori infection by upper esophagogastroduodenoscopy (EGD) and gastric biopsy.

Alterations in the intestinal microbiota have been associated to disease pathogenesis in ulcerative colitis. Refractory disease to standard medical therapy as corticosteroids often leads to an unfavourable course in patients suffering from this disorder. This study proposal aims at investigating changes in the intestinal microbiota that can predict a therapy refractory course of ulcerative colitis (UC) and may be used to identify high risk patients in an early phase of their disease.

Vedolizumab is a medicine that helps to reduce symptoms of IBD and the associated inflammation in the digestive system for participants with ulcerative colitis or Crohn's disease. In this study, participants with ulcerative colitis or Crohn's disease will be treated with vedolizumab according to their clinic's standard practice. Participants will receive vedolizumab as either an infusion or an injection just under the skin (subcutaneous). The main aim of the study is to observe real-world treatment patterns in participants treated with vedolizumab. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.

All episodes of patients with acute UC admitted to Tampere University Hospital and treated with intravenous corticosteroids between January 2007 and January 2016 were identified from patient records and reviewed. The risks for colectomy and for continuous use of corticosteroids were evaluated. Predictive factors were analysed.

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. Postoperatively, a detailed software-based assessment of each pouch recording is performed to determine the objective ICG-NIRF perfusion rate, which is then correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.

This project aims to evaluate the data on all patients undergoing endoscopic therapy for upper gastrointestinal bleeding.

Ulcerative colitis (UC) is a chronic remitting and relapsing inflammatory bowel disease. The pathogenesis is multifactorial, involving genetic predisposition, epithelial barrier defects, dysregulated immune responses, and environmental factors. It is diagnosed through colonoscopy and histological evidence of mucosal inflammation involving predominantly the rectum and potentially extending continuously up to the proximal segments of the colon. The patients affected present with severe abdominal pain, bloody diarrhea together with extraintestinal manifestations such as peripheral arthritis, pyoderma gangrenosum, erythema nodosum, ankylosing spondylitis and many others. The last 20 years have been profitable from the therapeutical point of view thanks to the advent of biological drugs which are derived from a living organism or its products including antibodies, interleukins and other molecules capable to target specific cellular pathways and to modulate different mechanisms such as blocking the actions of cytokines or white cells movement in the gut. More recently new promising alternatives seems to be the so-called small molecule drugs which are chemically derived low molecular weight compounds capable to enter the cell to regulate its functions and more generally biological processes like inflammation. In the last years, the therapeutic offer for ulcerative colitis patients has been enriched with the advent of biologics with different mechanism of action and very recently with the availability of the small molecules. Currently the available therapeutic options for ulcerative colitis include topic and systemic mesalazine, topic and systemic glucocorticoids, immunosuppressants (thiopurines), biological drugs (anti-tumor necrosis factor α (TNFα), inhibitor of α4β7 integrin, anti-IL12-23) and small molecules (JAK inhibitors). However, if on the one hand the therapeutical enrichment has clearly improved the disease rate control, still there is the need to perform sequencing study to stratify the available options to provide the best and most appropriate patient-oriented management.
