Filter by:The purpose of this pilot study is to compare the dynamic response of microcirculation in the skin on the bottom of the big toe after applying controlled plantar stress in 25 diabetic subjects with a history of foot ulcer and 25 age-matched healthy controls to better understand the role of local hypoxia in neuropathic foot ulceration in subjects with diabetes. The investigators hypothesize that if they apply a gait simulating load to the plantar foot and measure microvascular function, diabetic individuals will demonstrate an increased delay in reestablishing microvascular flow compared to healthy individuals.
The purpose of this study is to determine whether the EpiFix human amniotic membrane is effective in the treatment of diabetic foot ulcers.
The primary objective of this study is to detect differences in anti-S. aureus antibody assays (IgM, IgA, IgG and its subclasses) between (1) a group of patients with bacteremia due to a chronic wound (cases) and (2) a group of patients with localized chronic wound infections (control).
Diabetic foot (DF) is a common, severe and costly complication of diabetes. DF is underlied by neuropathy, atherosclerosis of distal arteries and infection, which result in tissue ulcers and necrosis. Alterations in microcirculatory function and in blood rheology may concur in causing tissue damage. In recent years there has been accumulating evidence that LDL apheresis (LA) does not only reduce cholesterol but also has a series of pleiotropic effects that improve the microcirculation, increasing peripheral tissue perfusion. HADIF is a randomized, multicentric, prospective clinical study aimed at assessing the effect of LDL apheresis treatment in association with traditional therapy for ulcers, in patients with an ischemic diabetic foot ulcer (class I and II Texas Wound Classification System)and peripheral vasculopathy not susceptible to revascularization. A total of 132 patients will be enrolled. Participants will be centrally randomized to receive traditional therapy alone (TT) or in association with LA. TT includes standard medication of ulcers, antiaggregant therapy and statins. LA will be performed with HELP system, for a total of 10 sessions in 9 weeks. The primary end-point of the study is ulcer healing; secondary endpoints include improvements of peripheral oxygenation, resolution of pain, reduction of circulating inflammatory markers, cardiovascular events during one year's follow-up. This clinical Study has been approved by local EC on 25 may 2011 (Study number 1953). TO BE NOTED: since diabetic patients in our "Diabetic-Foot UNIT" often presented foot ulcers more severe than class II Texas, a formal amendment has been submitted to EC for recruiting patients with diabetic foot ulcer of class III Texas. The amendment was already approved on 5 may 2012.
This study is for Type I or Type II diabetic subjects with with a diabetic foot ulcer. The study is being done to determine if Nexagon® plus standard of care is more effective than placebo plus standard of care. Standard of care will include debridement of the ulcer, standardized dressings and standardized off-loading using a Removable Cast Walker.
On behalf of a consortium of 19 health insurance companies the Institute for Research in Operative Medicine as part of the University of Witten / Herdecke gGmbH is planning and conducting a clinical study evaluating the efficacy and effectiveness of negative pressure wound therapy in the treatment of wound healing disorders of the foot, which are caused by diabetes mellitus. This german multicenter study is due to evaluate whether the negative pressure wound therapy or the control therapy (standard wound therapy following the guidelines) is superior. Patients will be randomly assigned to the two study arms. Both patients and the treatment staff know about the specific allocation to the negative pressure wound therapy or standard wound therapy arm. A photo documentation and a computer-based evaluation of the wound images will be performed. This is done centrally by independent examiners, who don`t know neither the patient nor the treatment assignment. It is believed that the application of the negative pressure wound therapy systems compared to standard therapy of diabetic foot wounds will lead more frequent and more rapid to the achievement of complete wound closure and that the use of negative pressure wound therapy is an effective and safe therapy option for the treatment of diabetic foot wounds in inpatient and outpatient care. Patient´s to be included into the study should have either a chronic diabetic foot wound existing longer than 4 weeks whereas dead tissue components must be completely removed by the doctor or a wound after amputation of foot parts. The study treatment may have already started in the hospital if applicable. The further wound treatment will be mainly performed within outpatient care. Study Participants will return to the study centre for regular study visits or even for wound treatment. The comparison of the outcomes of both study arms will give valuable information about the efficacy of negative pressure wound therapy in inpatient as well as outpatient care. These results should be provided until the end of 2016 as a basis for the decision of the Federal Joint Committee to answer the question if the negative pressure wound therapy can be approved as a standard service for reimbursement by health insurance companies.
CACIPLIQ20 is a nanopolymer engineered to mimic glycosaminoglycans such as heparan sulfates. Glycosaminoglycans are implied 1) in the stabilization of the micro-environment of cells, known as extracellular matrix, by binding to structural proteins, and 2) in the cell communication by protecting growth factors. At the site of a lesion, glycosaminoglycans are degraded, thereby the extracellular matrix is disorganized and the tissue is destroyed. By replacing damaged glycosaminoglycans, CACIPLIQ20 provides a protective function and restores the matrix architecture and the cell communication, a process known as Matrix Therapy. As for now, three non-controlled pilot studies have been carried out on small populations. They have shown a substantial enhancement of chronic wounds state after treatment with CACIPLIQ20. Therefore, the purpose of this new controlled study is to determine whether CACIPLIQ20 can shorten diabetic neuropathic plantar ulcers healing when the off-loading is mandatory. The study's main hypothesis is that CACIPLIQ20 application on a non-healing diabetic plantar ulcer in an off-loading mandatory context would reinitiate the natural process of tissue regeneration and lead to total wound closure faster than following standard wound care.
The LeucoPatch™ study goal is to investigate whether the fully autologous growth factor-containing dressing LeucoPatch™ has a positive effect on healing rates of diabetic foot ulcers. The study seeks to gather data for comparison with previous data from similar wounds (historical controls). By subgrouping of the treated wounds (similar to the historical controls used) an assessment of which of the patient and wound-related factors that might indicate a beneficial effect of LeucoPatch™ is sought.
The primary objective of this study is to assess the effectiveness of cellular dermal replacement tissue vs. non-viable extracellular matrix (ECM) for the treatment of non-healing diabetic foot ulcers. Our hypothesis is that these devices are of equal efficacy.
The purpose of this study is to determine if topical application of a hydrogel that contains plant extracts will improve healing of diabetic foot ulcers when compared to treatment with a hydrogel alone.
