Filter by:The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active ulcerative colitis (UC).
This registry on Tofacitinib and biologics (anti-integrin/anti-TNF) in the treatment of ulcerative colitis (UC) patients in Germany will extend the prospective documentation of safety issues and efficacy in induction and maintenance therapy of Tofacitinib (Xeljanz®) in addition to other biologics used in Germany with a particular interest in predictors of long-term responses and favorable disease outcome or to predict severe side effects caused by therapy with Januskinase(JAK)- inhibitors/biologics.
CytoMegaloVirus (CMV) infection impairs evolution of Ulcerative Colitis (UC) leading to more severe and resistant to immunosuppressive therapies flare-up. CytoMegaloVirus (CMV) reactivation is assessed by the quantification of the CytoMegaloVirus (CMV) DeoxyriboNucleic Acid (DNA) load by real-time PCR (qPCR) in colonic biopsies; this assay is invasive and costly. The QuantiFERON-CytoMegaloVirus (QF-CMV) assay measures the immune response against CytoMegaloVirus (CMV) in a blood specimen.
The aim of this study is to determine the efficacy and safety of Beta-1,3/1,6-D-Glucan from mycelium extract of Ganoderma lucidum on ulcerative colitis
Challenges in the treatment of Helicobacter pylori (H. pylori) include increasing antimicrobial resistance and patient's low tolerance to some regimens. Lactobacillus johnsonii (L. johnsonii) and Immunoglobulin Y (IgY) have been shown to decrease the amount and activity of H. pylori in human stomach and can increase patient's tolerance. We conduct a single-center double-masked randomized controlled trial to evaluate the effectiveness of GastimunHp Plus (a product combining L. johnsonii and IgY) in improving the clearance of H. pylori after six to eight weeks of treatment and side effects of H. pylori treatment. H. pylori is tested by C13- or C14-urea breath test.
This randomised study will assess whether Parafricta bootees, when used in addition to normal standard care, can reduce the incidence of heel PUs in patients at very high risk of skin breakdown. The participant group will be hospital inpatients at high risk of PUs (Waterlow score of 20 or more) who are bedbound and do not have existing heel PUs. The participants will be randomised to an intervention arm using Parafricta plus standard care, or a control arm of standard care only. The primary outcome is incidence of heel PUs at day 3. Secondary outcomes are incidence of PUs at day 14, length of stay, severity of PUs, patient acceptability of device, cost-effectiveness.
A phase 2b study to evaluate the long-term efficacy and safety study of ABX464 50mg as maintenance therapy in patients with moderate to severe Ulcerative Colitis.
Determine if the use of platelet rich fibrin (PRF) improves the rate and quality of healing for intraoral mucosal and epithelial soft tissue defects.
Background and rationale: Venous leg ulcers (VLU) are slow healing wounds with a recurrence rate of 70% and a 60% risk of becoming chronic. The estimated VLU prevalence in the general population is 3%. Current therapeutic approaches are multifaceted and focus on reducing wound size and improving wound healing as well as preventing ulcer recurrence. They require a pluridisciplinary team of health care professionals from the domains of nursing, medicine, physiotherapy and nutrition. Approximately 70% of VLU patients have a knowledge deficit in regards to therapeutic measures and have difficulties with adherence to treatment protocols. However, there are no published studies describing and evaluating the impact of pluridisciplinary educational interventions on adherence to the treatment plan and wound size reduction in VLU patients. Overall objectives: The objectives of the projected study are to evaluate the effectiveness of nurse-led intervention for high-risk patients with VLU in terms of patient knowledge/therapy adherence and to measure the impact of this intervention on wound size reduction and its evolution over time. Methodology of the planned study: An international multicenter randomized controlled trial with 248 participants in three Swiss French (n= 124) and two Australian (n=124) wound clinics is proposed. The sample size assumptions are based on a two-sided alpha level of 0.05, power of 0.8, and a medium effect size. Univariate and bivariate analysis will be conducted according to the data level and distribution. Expected results and impact: The findings of this study will generate new knowledge and the results will contribute to VLU clinical practice guidelines to enhance patient adherence to therapy. Our results will not only help improving patients' quality of life, but also contribute to reducing health expenditure.
Multi-center study on the effectiveness of treatment with a blue light medical device (EmoLED) in the reduction of ulcer surface in 10 weeks. The aim of BLUR clinical trial is to verify if the proposed treatment represents a valid and significant remedy for Chronic Venous Insufficiency ulcers. The effectiveness will be measured through the evaluation of the reduction percentage of the lesion area during 10 weeks of treatment comparing the lesion (or portion of it) treated with EmoLED versus the control lesion (or portion of it) treated only according to current Standards of Care(SOC). In the 10 weeks following the recruitment, the patient continues to follow the usual topical therapy with a frequency of once a week visit. The patient will be monitored up to the first event occurring: Complete healing or ten weeks. During the study, reports and evaluations will be made by medical staff on the device safety and usability. 90 patients will be recruited corresponding to the following criteria: - Subjects suffering from venous, arterial and mixed skin ulcers and surgical dehiscence lesions; - Presence of similar multiple lesions or lesions larger than 5 cm ; - Men and women ≥ 18 years old; - The patient must be able to understand the aims of the clinical study and provide informed consent in writing; - Chronicity of the lesion: at least 8 weeks. The present clinical trial will be a multi-center prospective, controlled study with the aim of verifying the clinical efficacy of a portable battery-powered device based on blue LEDs. We expect to record at least 20% of the difference between treated lesion and untreated lesion on the same patient during observation time. The treatment, additional to the standard therapy for the patient, will be performed at each visit for 60 seconds on each 5 cm diameter sub-area of the selected lesion or on part of it. In case of multiple lesions, one will be treated with EmoLED and one will be selected as a control lesion. In case of a very extensive lesion, it will be divided into two and one half will be the control of the other. All lesions will be cleansed with saline solution and a surgical debridement will be performed with a scalpel if a slough/black base is present. Only then the treatment with EmoLED will begin. If the patient has more than one lesion at the recruitment time, and all lesions are less than 5 cm in diameter, the worst lesions will be treated entirely with the EmoLED device and the others will constitute the control lesions. The evolution of all lesions in the ten weeks of the study duration will be evaluated. If the patient has only one lesion greater than 5 cm in diameter at the recruitment time, the lesion will be divided into two parts along the major side and one half of the lesion area will be treated. The other half of the lesion will be masked with multi-layered sterile gauze during treatment. The point of division of the lesion into two parts will be indicated with an indelible marker and retouched at each visit. If, at the time of recruitment, the patient has more than one lesion with a diameter greater than 5 cm, all lesions will be divided into two along the major side and will be treated as in the previous case. After treatment with EmoLED, a hydrofiber dressing will be applied to the lesion. If clinical signs of infection occur, a hydrofiber dressing with silver will be applied. If necessary, compressive bandage of the limb will be carried out.
