Filter by:Ulcerative colitis is a chronic idiopathic inflammatory disease of the colon that is characterized by abdominal pain and bloody diarrhea. The pathogenesis of UC involves a complex interplay of genetic factors, immune dysregulation and environmental triggers. Conventional therapies for UC (including 5-aminosalicylates, corticosteroids, azathioprine or 6-mercaptopurine and biologics) focus on altering the immune response by suppression of immune cells. However, the primary pathogenic mechanism underlying UC maybe gut microbiota dysbiosis and a dysfunctional intestinal barrier resulting in an aberrant host immune response. Several studies have shown reduced microbial diversity in UC patients with under representation of anti-inflammatory phyla (Bacteroides and Firmicutes), and a relative increase of pro-inflammatory phyla (Proteobacteria and Actinobacteria). Motivated by this, therapies targeting intestinal dysbiosis (prebiotics, probiotics, synbiotics and fecal microbiota transplant (FMT)) have thus been tried in patients with UC. Though several case series and subsequently four high quality randomized controlled trails have established the efficacy of FMT in induction of remission in active UC, all these studies have used it as an add-on therapy, along with the previously ongoing conventional therapies. The investigators aim to assess the safety and efficacy of FMT as the sole modality for induction of remission in patients with newly diagnosed active UC.
The laser emits an infrared light that heats the skin and underlying tissues with the purpose of temporary relief of minor muscle and joint pain, as well as stiffness associated with arthritis. The laser also causes a temporary increase in blood flow. The purpose of this study is to evaluate whether laser therapy can provide pain relief and speed the healing of venous leg ulcers.
Negative Pressure Wound Therapy (NPWT), is a non invasive wound management tool which develops from negative pressure being applied to the wound. This promotes healing through the removal of infectious materials and enhancing granulation tissue formation. NPWT eases debridement as well as promoting healing of different types of wounds.
Mucosal healing or histological remission is an important target for the treatment of inflammatory bowel disease. In this study, patients with mucosal healing are defined as a control group, observing their clinical outcomes for 3 years, and describing the recurrence rate. The secondary objective is to study the operative rate, glucocorticoid utilization rate, treatment escalation rate, hospitalization rate and incidence of related complications.
The aim of this study is to assess the ability of miR-320a and other specific microRNAs to follow the disease course in patients with Crohn`s disease (CD) and ulcerative colitis (UC), and to distinguish both entities, infectious colitis and healthy controls. Furthermore, the accuracy of miRNA-320a to distinguish CD or UC from irritable bowel syndrome (IBS) should be evaluated . The study is designed as a single center non-randomised prospective trial.
The global prevalence of diabetes is on the rise and with it increase in prevalence of diabetic foot ulcers (DFU). These recalcitrant wounds are difficult to manage and pose a heavy economic burden. Photobiomodulation (low level laser) is used for acceleration of wound healing. The current study is designed to evaluate the effectiveness of B-cure laser, a home-use low-level laser device, for acceleration of diabetic foot ulcer healing over standard treatment.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that results from immune dysregulation. Arguably, the development of Tumor Necrosis Factor (TNF) antagonists (including infliximab, adalimumab and golimumab) revolutionized the management of immune-mediated chronic diseases in the past two decades. However, about one third of patients will not respond to a first anti-TNF treatment and 10% to 30% will loose response to anti-TNF during the follow-up. Historically, a switch between anti-TNF was performed to recapture remission and response to anti-TNF. Recently, a new biologic therapy blocking another target has been approved and is now reimbursed during ulcerative colitis, namely vedolizumab. Vedolizumab is an anti-integrin agent avoiding the recruitment of lymphocytes specifically in inflamed gut tissue. Emerging data suggest that a switch of therapeutic class (meaning a change of biologic target with Non-TNF-targeted biologic) in case of clinical failure or insufficient response to anti-TNF may be the best choice. This idea of a switch out of the anti-TNF class is also supported by data on drug monitoring that may help physician decision making in case of loss of response. However, no trial is currently available and ongoing to assess the best therapeutic strategy. The aim of the proposed study is to assess the best biological based strategy in patient losing response to a first subcutaneous anti-TNF (golimumab and/or adalimumab).
Patients with a history of idiopathic gastroduodenal ulcer bleeding face an increased risk of recurrent ulcer gastrointestinal bleeding. Our ongoing clinical trial demonstrates a possible reduced risk of recurrent idiopathic gastroduodenal ulcer bleeding with proton pump inhibitor (PPI), yet there is a significant risk of recurrent ulcer bleeding as PPI may increase the risk of small bowel bleeding. Our preliminary data provide strong plausibility that a combination therapy of misoprostol (MISO) with a PPI reduces the recurrent ulcer bleeding as well as clinical gastrointestinal bleeding. The investigators are going to provide the definitive answer to this important clinical question through a randomised trial.
Ulcerative colitis (UC) is a chronic, progressive immunologically mediated disease affecting nearly 1 million Americans. Up to one third of patients with UC will require hospitalization for severe disease (termed 'acute severe colitis (ASUC)'), often within the first year after diagnosis. Investigators will develop a large multi-center cohort of patients with ASUC with homogeneously collected detailed longitudinal clinical and laboratory data.
