Filter by:The primary objectives of this study are as follows: 1) To evaluate the efficacy of andecaliximab to induce endoscopy, rectal bleeding, and stool frequency (EBS) clinical remission at Week 8 (Cohort 1); 2) To evaluate the efficacy of andecaliximab to maintain EBS clinical remission at Week 52 (Cohort 2); and 3) To evaluate the safety and tolerability of andecaliximab. The study will consist of 3 parts: Induction Phase (Cohort 1), Maintenance Phase (Cohort 2), and an optional Extended Treatment Phase.
To evaluate the VAC (Vacuum Assisted Closure) therapy in transplants of leg ulcers versus usual dressing method. The VAC Therapy system consists of: - A unit delivering a precise under atmospheric pressure, controlled and regulated in the wound site, - Consumables necessary for the implementation of the dressing, - Collecting tanks exudates with gel. VAC therapy is a system using negative pressure. It is known to be efficient into care of chronic wounds and ulcerous wounds by increasing the cicatrisation. This system is systematically used into the dermatology unit of the CHU of Saint-Etienne after transplants of leg ulcers, but no data confirms the interest of this method compared to usual dressing method. This study will provide this data.
Ulcerative colitis (UC) is an immune mediated chronic inflammatory bowel disease that results at least in part of an abnormal immune response to environmental factors including the intestinal microbiota. Thus, use of probiotics (microorganisms that are believed to provide health benefits when consume) may restore the gastrointestinal microbiota and reduce intestinal inflammation. Propionibacterium freudenreichii is used for the production of fermented food products (cheese). Some selected strains have strong anti-inflammatory properties. Use of cheese based on a monoxenic culture of anti-inflammatory strain of Propionibacterium freudenreichii may decrease disease activity during ulcerative colitis.
The purpose of this study is to compare how well two products, Active Leptospermum Honey (ALH) (MEDIHONEY® Gel) and Collagenase (Santyl®), in removing the nonviable (non living) tissue.
The main objective of this study is to document the effectiveness of a honey-based medical device (Hyalumel) in the management of pressure ulcers. The effectiveness of the medical device will be judged according to the evolution of the surface of the wound at the end of 12 weeks of treatment.
A prospective, multicenter, randomised controlled phase II study in which patients with therapy resistant (arterio-) venous leg/foot ulcers are treated with Tiscover® (test group) or with AS210 (control group) to determine the safety and relative efficacy of both products.
Bleeding peptic ulcer is a common medical emergency. Endoscopic treatment stops bleeding in those actively bleeding from their peptic ulcers, reduces further bleeding, transfusion, surgery and deaths. After initial endoscopic control of bleeding, approximately 10% of them will develop recurrent bleeding. Mortality rate in this group of patients is at least 4 fold higher. In the few who need surgery, mortality approaches 30%. Prevention of further bleeding is therefore a major treatment objective. Currently the investigators use a high dose infusion of proton pump inhibitor (PPI) for 72 hours to render gastric pH neutral. In a previous randomized trial, the investigators showed that the rate of bleeding in 30 days was around 7% with such an approach. In a small subgroup of high risk patients defined by presentation with shock and ulcers > 2 cm in size, 1 in 6 would re-bleed. An alternate strategy is to select those at especially high risk of further bleeding and repeat endoscopic treatment the next morning. The investigators have shown that persistence of major bleeding stigmata, i.e. a visible vessel, during a second endoscopy predicts further bleeding. It is therefore logical that by repeating endoscopic treatment the next morning, the investigators can prevent further bleeding and possibly surgery and deaths. The current study proposes to develop a score to identify those at risk of further bleeding after endoscopy. The investigators used a historical cohort with carefully collected clinical data to derive a risk score. In this derivation phase of 939 patients, the investigators have developed a 9 point risk score which consists of the following parameters (Age>60, Male sex, ulcer>2cm, posterior bulbar in location, spurting or Forrest Ia bleeding and admission hemoglobin of < 8 g/dl). Using AUROC and Youden J statistics, a score of 5 or above has been shown to highly predictive of further bleeding. The score will then be validated in a prospective cohort of patients with bleeding peptic ulcers. In the final phase of this study, the investigators propose a randomized controlled trial to test the hypothesis that a second look endoscopy with treatment in selected high risk patients can further reduce bleeding and improve their outcomes. After endoscopic hemostasis to their bleeding peptic ulcers, patients are risk stratified based on the score. Those with a score of 5 or more are randomized to receive the standard treatment (a high dose PPI infusion) or a second look endoscopy with treatment in addition to PPI infusion. The primary outcome to the trial is further significant clinical bleeding.
This efficacy study evaluates the safety and effectiveness of aspirin for venous leg ulcer healing. The study also examines whether patients can be recruited to a larger study. Patients with chronic venous leg ulceration presenting and undergoing care in leg ulcer community clinics or hospital out-patient clinics, or registered with a clinic but are receiving care at home will be recruited. All patients will receive standard compression bandaging. Half of the participants will be randomised to receive aspirin, while the other half will receive a placebo.
