Filter by:This is a pilot study to evaluate the treatment effect of INP on wound healing and tissue perfusion for a larger randomized controlled trial (RCT). This randomized cross-over pilot study will look at the effects of intermittent negative pressure (INP) therapy wound healing and the peripheral macro- and microcirculation in spinal cord injured patients with chronic leg and foot ulcers (6 weeks or more at inclusion). The project is designed as a randomized clinical trial with single-subject multiple baseline design. We will perform convenience sampling of spinal cord injured patients with leg and foot ulcers, with the last recruitment by the end of december 2016.To ensure equal distribution of participants in each study arm, we will perform block randomization. A statistician will randomized patients to either intervention arm or control arm before start of the study: At baseline, each participants will be randomized into either A) 8 weeks without intervention OR B) 8 weeks with start INP therapy 2 hours per day divided into 2-3 timed sections. After the 8 weeks, participants in the the control group (A) will be re-examined, and start 8-week INP therapy. Also the intervention (INP) will be subjected to the same lower limb in each individual throughout the study period. The other leg will act as a intra-individual control. At baseline (week 0), and during the course of the study (every 4th week), the participants' wounds will be measured by a wound nurse. Baseline (before start of INP therapy) and after intervention the following measures will be performed: Demographic data (weight, height, ABI), Segmental pulse-volume-recording, Segmental skin perfusion pressure with a laser Doppler sensor and a pressure cuff to evaluate reactive hyperemia (Sensilase, Väsamed) and health surveys (SF-36/EQ-5D-5L and customized wound questionnaire) or similar will be examined at baseline and and the end of the study period. Otivio AS has supplied the FlowOx devices and provided the necessary training to perform this project. Outcome variables assessed before and after the study period will be: wound healing (primary endpoint), quality of life (secondary endpoint), skin perfusion pressure (secondary endpoint), ankle-brachial pressure (secondary endpoint) and segmental pulse-volume recording (secondary endpoint). The aim of this project is to prospectively examine and elucidate the effect of intermittent negative pressure therapy applied to a limited part of the lower limb on clinically relevant measures related to wound healing and peripheral macro- and microcirculation in patients with spinal cord injury. The hypotheses of the study are: - Application of INP in patients with spinal cord injury, by the use of the FlowOx™ device, will improve wound healing in the foot compared to before treatment (baseline) and compared to standard wound care alone. - Application of INP in patients with spinal cord injury, by the use of the FlowOx™ device, will improve macro- and microcirculation in the foot compared to before treatment (baseline) and compared to standard wound care alone in patients with spinal cord injury. - Application of INP in patients with spinal cord injury, by the use of the FlowOx™ device, will improve macro- and microcirculation in the intervention foot compared to the control foot and compared to standard wound care alone in patients with spinal cord injury.
Diabetic foot ulcer (DFU) is a major complication and the leading cause of hospitalization among people with diabetes mellitus. It occurs in 15% of all patients with diabetes and precedes 84% of all lower leg amputations. Despite many therapeutic advances over the past decades, including dressings (hydrocolloids, alginate, skin substitutes) and growth factors, healing rates of DFU remain low. Mechanisms of faulty wound healing in diabetic patients are complex, related to both intrinsic and extrinsic factors. The main reasons for impaired healing appears to be: 1/exhaustion of local cell populations that promote wound healing; 2/excessive production of matrix metalloproteases (MMPs) coupled with reduced expression of the tissue inhibitors of MMPs; 3/impaired neovascularisation coupled with reduced numbers of endothelial progenitor cells and impairment of their functioning. These imbalances may result in excessive degradation of extracellular matrix components, as well as an inappropriate local inflammatory response . Adipose-derived stroma vascular fraction provides a rich and easily accessible source of autologous cells for regenerative medicine applications. Il contains multipotent stem cells and progenitors called adipose-derived regenerative cells (ADRCs) able to stimulate wound healing. There are attracted to the wound site where they supplement the wound bed with similar cell types, secrete numerous growth factors and cytokines, increase macrophage recruitment, enhance granulation tissue, and improve vascularisation . The reparative capabilities coupled with good safety of ADRCs have been illustrated in a study for treating severe and irreversible radiation-induced lesions, and in a study for treating sclerodactyly in patients with diffuse scleroderma. Numerous case reports showing healing of refractory wounds following treatment with autologous ADRCs have also been reported. Based on these previous reports, the present study aims to assess the efficacy and tolerance of injection of ADRCs for the local treatment of neuropathic or neuro-ischemic DFU.
The aim of the study is to evaluate participant reported quality of life, safety, and overall performance with ACTICOAT in a clinical setting.
Leg and foot ulcers due to venous disease or diabetes are chronic wounds that can take 6 or more months to heal. Growth factors have been used to try and improve this healing, however, many such studies have failed, and that is thought to be due enzymes in the wound that degrade the growth factors and prevent them from working. This is a proof of concept study that will evaluate the treatment of chronic leg ulcers with topically applied growth factors that are combined with a therapy to prevent their inactivation in the wound.
A Multicenter, Prospective, Randomized Controlled Comparative Parallel Study To determine the safety and effectiveness of EpiCord as compared to standard of care (SOC) therapy for the treatment of chronic, non-healing diabetic foot ulcers (DFUs)
This study will compare the proportion of patients who have wound closure within 12 weeks as well as the time to wound closure in patients receiving Artacent™ versus standard of care for treatment of non-healing lower extremity wounds. The recurrence of healed wounds will be assessed at 6 months via a telephone survey
This trial will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of repeat dosing of UTTR1147A in participants with neuropathic diabetic foot ulcers that do not respond adequately to standard wound care. Participants across multiple sites will be assigned to one of five cohorts (Cohort A, B, C, D, and E) based on the eligibility criteria and randomized to receive subcutaneous (SC) injections of either UTTR1147A or placebo over 12 weeks in addition to standard wound care.
This is a prospective study of participants with diabetic foot ulcers who will receive either maggot debridement therapy (MDT) or conventional dressing therapy (CDT). Wound healing time is the main outcome measure to compare the clinical efficacy of these two therapies. The investigators developed a hypothesis that MDT could achieve remarkable shorter time and better healing rate for wound closure when compared with CDT.
This is an observational, longitudinal real world registry of diabetic foot ulcers created from electronic health record data obtained in the course of clinical care. Data from certified electronic health records transmit data as part of the requirement to share data with a specialty registry under Objective 10 of Meaningful Use of an EHR.
This prospective case series is to gain additional clinical experience in the treatment of diabetic foot ulcers, by documenting and relating patient history (including baseline wound characteristics) and clinical outcomes (incidence of healing, rate of healing, and patient and physician satisfaction) in a group of study participants for whom the ReGenerCell™ Autologous Cell Harvesting Device (ReGenerCell™) is used in combination with conventional therapy for the closure of diabetic foot ulcers (DFUs). Participants will receive ReGenerCell™ treatment in addition to standard care (debridement, cleansing, dressings, offloading).
