Filter by:This is a twelve-week single-center, randomized, double-blind, clinical study to evaluate the safety and efficacy of a folic acid wound treatment (FAWT) versus Placebo in the promotion of healing of chronic, early stage diabetic foot ulcer (ES-DFU) wounds. Male and female Veterans with type-2 diabetes mellitus and chronic ES-DFUs acceptable to the study inclusion/exclusion criteria will be considered for enrollment.
Approximately 20-40% of patients with ulcerative colitis (UC) are obese. The investigators have demonstrated that obesity adversely impacts disease course in patients with UC, leading to higher risk of persistently active disease, surgery, hospitalization, and treatment failure, particularly in biologic-treated patients. Intentional weight loss is effective in improving disease outcomes in patients with inflammatory arthritis, but there is limited data on its impact in UC. While dietary interventions for weight loss have limited efficacy and endoscopic bariatric interventions may be too invasive in patients with UC with active gastrointestinal symptoms, pharmacological weight loss with a highly effective oral agent may be a novel strategy to induce weight loss and augment the efficacy of biologic therapy in UC. Hence, the investigators are conducting a pilot, phase 2A, 22-week, randomized, placebo-controlled clinical trial of phentermine-topiramate in obese patients with active UC starting on a new biologic agent (infliximab, adalimumab, golimumab, vedolizumab). The overall objective is to (1) evaluate the efficacy, safety and tolerability of phentermine-topiramate, and (2) to assess the impact of pharmacological weight loss on clinical outcomes, inflammatory burden and biologic trough concentration in patients with UC. The central hypothesis is that phentermine-topiramate will be safe, effective, and well tolerated in patients with UC, and weight loss would achieve higher rates of clinical and biochemical remission, and higher biologic trough concentration.
The present study D5272C00001 (Legacy # 3151-201-008) seeks to evaluate the efficacy and safety of brazikumab versus placebo in patients with moderately to severely active UC and will include assessments of clinical responses as demonstrated by improvement of symptoms and of colonic mucosal appearance as observed on endoscopy.
The investigators aimed to elucidate the effects of ultrasound debridement on the area and healing of diabetic foot ulcers compared to their conventional treatment.
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.

Umbilical cord blood mononuclear cells (MNC) may improve the wound repair ability. This study aims to investigate the role of MNC in refractory diabetic foot ulcer by comparing the combination of PRP and MNC with PRP alone.
Skin ulcer is a common disease with complicated etiopathogenes, which makes it hard to be cured. It has been reported that photodynamic therapy (PDT) can be used to treat skin ulcers which were caused by different diseases. However, PDT is an expensive treatment and patients always experience obvious pain during or after the treatment, which hinders the application of PDT in skin ulcer. Our previous study found that PDT using a low concentration of 5-Aminolevulinic acid (ALA) could promote the healing of skin ulcer without obvious adverse reactions, which suggests us that low concentration ALA-PDT might be an efficient and cost effective treatment in skin ulcer. To further investigate the use of low concentration ALA-PDT in skin ulcer, we plan to recruit patients with skin ulcers caused by different diseases, and divide these patients into different groups according to their causes of disease, and then treat them using low concentration ALA-PDT to observe the healing process of skin ulcer. This study could further optimize and promote the use of low concentration ALA-PDT in skin ulcer.
Multi-center, prospective,randomized controlled study on the speed of healing, life quality and cost-effectiveness of the treatment with a blue light medical device (EmoLED) versus existing Standards Of Care (SOC) for patients with leg ulcers. The aim of LUCE - "Leg Ulcers Standards of Care Enhancement" clinical trial is to verify the clinical efficacy of a portable battery-powered device blue LEDs based. This study aims to compare the existing SOC (consisting in two visits per week) to a protocol that requires only one visit per week, during which the EmoLED treatment is administered in addition to the current therapy. It is expected to register a difference in efficacy between EmoLED Group and SOC Group, in terms of "healing rate", intended as a reduction of the wound area, but also as a progress, in a broad sense, of the overall clinical situation of the lesion, in terms of pain and quality of life. -Endpoint- The primary endpoint is the comparison of the outcomes in terms of healing rate of lesions treated with SOC (SOC Group) versus lesions treated with EmoLED (EmoLED Group), on week 16th. Patients 80 patients will be recruited (40 patients per group), following these inclusion/exclusion criteria: Inclusion criteria: - Subjects suffering from venous and mixed skin ulcers; - Presence of a lesion < 100 cm² of area and < 1 cm in depth; - Men and women ≥ 18 years old; - The patient must be able to understand the aims of the clinical trial and provide informed consent in writing; - Chronicity of the lesion: at least 8 weeks. Exclusion criteria: - Patients who participated in clinical trials about skin ulcers healing during the previous month; - Patients who are not able to understand the aims of the trial; - Patients with pressure ulcers; - Patients with diabetic foot ulcers; - Patients with circumferential leg ulcer (due to the difficulties in analysing the pictures); - Patients with clearly infected ulcers or with systemic infection; - Patients with ulcers caused by critical ischemia; - Patients with a self-harm past that can purposely alter the process of healing; - Patients with psychiatric disorders; - Pregnancy or breast feeding; - Patients with neoplasms or other diseases involving the use of cytostatic or immunosuppressive drugs; - Patients with limited lifespan; - Patients with photosensitizing illnesses or that take photosensitizing drugs. All inclusion and exclusion criteria must be satisfied before recruitment. Any concomitant phar-macological therapy must be maintained. -Medical and surgical procedures- The lesions will be cleansed with saline solution and, if necessary, surgical debridement will be performed with the most suitable method. At this point, if patient is included in EmoLED Group, the EmoLED treatment starts. After EmoLED application (EmoLED Group) or after cleansing (SOC Group), a polyurethane foam dressing will be applied on the lesion. In case of clinical signs of infection, a silver dressing will be applied. Then an elasto-compressive double layer dressing of the limb with cohesive fixation bielastic la-tex-free bandage will be carried out. The treatment with EmoLED, in addition to the SOC, will be performed during each visit for 60 seconds on each 5 cm diameter sub-area of the selected lesion. In case of multiple lesions matching with both inclusion and exclusion criteria, they will be all treated following the same protocol, depending on the group to which the patient belongs; in this case the Principal Investigator will fill out a data-collection form and take pictures just of the le-sion with the wider area. -Follow up procedure- The patient is called upon to go to the follow-up check after 4 weeks from the healing or, other-wise, from the end of the trial (16 weeks). The follow-up visit will be used to confirm the occurred healing and verify the absence of relapses and/or undesirable effects (if the wound appeared completely healed) or to value the healing progress for the unhealed lesions.
In this FinUC study we are trying to find out the efficacy and safety of the Fecal microbiota transplantation (FMT) in newly diagnosed active ulcerative colitis patients. The study group with newly diagnosed active ulcerative colitis receive an FMT via colonoscopy from a tested general donor, frozen and thawed from a fecal bank at week 0 and at week 4 as an enema at the study nurse´s visit. The control group will be given colored water. The main aim of the FinUC study is to determine how the FMT change of the gut microbiota composition in newly diagnosed active ulcerative colitis patients. The other aim is to determine efficacy and mechanisms of fecal microbiota transplantation.
