A purified reconstituted bilayer matrix shows improved outcomes in treatment of non-healing diabetic foot ulcers when compared to the standard of care: Final results and analysis of a prospective, randomized, controlled, multi-centre clinical trial.

As the incidence of diabetic foot ulcers (DFU) increases, better treatments that improve healing should reduce complications of these ulcers including infections and amputations. We conducted a randomized controlled trial comparing outcomes between a novel purified reconstituted bilayer membrane (PRBM) to the standard of care (SOC) in the treatment of non-healing DFUs. This study included 105 patients who were randomized to either of two treatment groups (n = 54 PRBM; n = 51 SOC) in the intent to treat (ITT) group and 80 who completed the study per protocol (PP) (n = 47 PRBM; n = 33 SOC).

The Use of Active Coagulation Whole Blood-An Innovative Treatment Strategy for Hard-To-Heal Wounds.

Background: Deep and tunneling wounds are a challenge to apply and maintain most advanced wound dressings to promote effective healing. An autologous whole blood clot is a topical treatment and has been found to be safe and effective in healing cutaneous wounds. The active coagulation whole blood (ACWB) clot treatment, using the patient's own blood, is used to treat deep and tunneling wounds, by mixing the blood with coagulation components and applying it into the wound cavity allowing the clot to re-form inside the wound.

Topical autologous blood clot therapy: consensus panel recommendations to guide use in the treatment of complex wound types.

The etiology of acute and chronic wounds goes beyond those often reported in the literature, including those with exposed structures, those in which the entire wound bed cannot be visualized, and patients who are not candidates for typical standard of care. Treatment options for these patients may be limited. TABCT is a viable option for these complex wound types and is not hindered by logistical, procedural, or patient factors.

Topical autologous blood clot therapy: an introduction and development of consensus panel to guide use in the treatment of complex wound types.

Complex or hard-to-heal wounds can be acute or chronic; the complexity is based on patient-specific local, systemic, and psychosocial factors. Use of autologous tissue can be a significant adjunct to wound closure. Grafts and flaps are the most common autologous tissue used in wound reconstruction.

A Multicenter, Randomized, Controlled, Clinical Trial Evaluating Dehydrated Human Amniotic Membrane in the Treatment of Venous Leg Ulcers.

Background: This randomized controlled trial evaluated the safety and effectiveness of weekly and biweekly applications of dehydrated human amnion and chorion allograft (dHACA) plus standard of care compared to standard of care alone on chronic venous leg ulcers.

Methods: This open-label randomized controlled trial included patients with chronic venous leg ulcers at eight wound care centers across the United States. The primary endpoint was the proportion of healed ulcers at 12 weeks.

Use of a purified reconstituted bilayer matrix in the management of chronic diabetic foot ulcers improves patient outcomes vs standard of care: Results of a prospective randomised controlled multi-centre clinical trial.

Diabetic foot infections continue to be a major challenge for health care delivery systems. Following encouraging results from a pilot study using a novel purified reconstituted bilayer matrix (PRBM) to treat chronic diabetic foot ulcers (DFUs), we designed a prospective, multi-centre randomised trial comparing outcomes of PRBM at 12 weeks compared with a standard of care (SOC) using a collagen alginate dressing. The primary endpoint was percentage of wounds closed after 12 weeks.

Functional Properties of a Purified Reconstituted Bilayer Matrix Design Support Natural Wound Healing Activities.

Unlabelled: Biomaterial engineering has produced numerous matrices for use in tissue repair, utilizing various materials and processing methods, which can impact the ability of the products to encourage wound healing. Recently, we observed favorable clinical outcomes, using a novel purified reconstituted bilayer matrix (PRBM; Geistlich Derma-Gide) to treat chronic diabetic foot ulcers.

Methods: Evaluations of the structural and functional characteristics of PRBM in vitro were performed to assess how this biomaterial may affect the favorable clinical results observed by influencing the wound environment and key physiologic mechanisms necessary for the healing process.

An observational pilot study using a purified reconstituted bilayer matrix to treat non-healing diabetic foot ulcers.

Diabetic foot ulcers (DFUs) have significant clinical impact and carry a substantial economic burden. Patients with DFUs that are refractory to standard wound care are at risk for major complications, including infection and amputation and have an increased risk of mortality. This study evaluated the safety and preliminary efficacy of a novel decellularised purified reconstituted bilayer matrix (PRBM) in treating DFUs.

Placental Membrane Provides Improved Healing Efficacy and Lower Cost Versus a Tissue-Engineered Human Skin in the Treatment of Diabetic Foot Ulcerations.

Unlabelled: Aseptically processed dehydrated human amnion and chorion allograft (dHACA) (AmnioBand) has shown great promise in the treatment of recalcitrant diabetic foot ulcers (DFUs) when compared with standard wound care but has not yet been compared to any other tissue forms used in treating DFUs. The hypothesis was to conduct a randomized controlled trial in which dHACA was compared to one of the earliest and most commonly accepted tissue-engineered skin substitutes (TESS) (Apligraf) in the treatment of nonhealing DFUs over a period of 12 weeks to assess the superiority of healing.

Methods: Following a 2-week screening period during which subjects with DFUs were treated with collagen alginate dressing, 60 subjects were randomized at 5 sites to receive either dHACA or TESS applied weekly, with weekly follow-up for up to 12 weeks.

Evaluating the Impact of Technique and Mesh Type in Complicated Ventral Hernia Repair: A Prospective Randomized Multicenter Controlled Trial.

Background: To our knowledge, there is an absence of prospective randomized multicenter controlled trials evaluating both the impact of technique and mesh type on outcomes in complicated ventral hernia repair.

Study Design: A prospective randomized multicenter controlled trial of 120 patients at 3 sites was conducted in which patients were randomized to either overlay (anterior component separation) or underlay mesh placement (posterior component separation) and mesh type (human acellular dermis [HADM] vs porcine acellular dermis [PADM]). Key inclusion criteria included hernia size (>200 cm), BMI < 40 kg/m, hemoglobin A1C < 7%, tobacco free > 6 weeks and primary fascial closure.

Use of an aseptically processed, dehydrated human amnion and chorion membrane improves likelihood and rate of healing in chronic diabetic foot ulcers: A prospective, randomised, multi-centre clinical trial in 80 patients.

Amnion and chorion allografts have shown great promise in healing diabetic foot ulcers (DFUs). Results from an interim analysis of 40 patients have demonstrated the accelerated healing ability of a novel aseptically processed, dehydrated human amnion and chorion allograft (dHACA). The goal of this study was to report on the full trial results of 80 patients where dHACA was compared with standard of care (SOC) in achieving wound closure in non-healing DFUs.

An aseptically processed, acellular, reticular, allogenic human dermis improves healing in diabetic foot ulcers: A prospective, randomised, controlled, multicentre follow-up trial.

Aseptically processed human reticular acellular dermal matrix (HR-ADM) has been previously shown to improve wound closure in 40 diabetic patients with non-healing foot ulcers. The study was extended to 40 additional patients (80 in total) to validate and extend the original findings. The entire cohort of 80 patients underwent appropriate offloading and standard of care (SOC) during a 2-week screening period and, after meeting eligibility criteria, were randomised to receive weekly applications of HR-ADM plus SOC or SOC alone for up to 12 weeks.

Human Reticular Acellular Dermal Matrix in the Healing of Chronic Diabetic Foot Ulcerations that Failed Standard Conservative Treatment: A Retrospective Crossover Study.

Background: Acellular matrices have been successfully used to heal indolent diabetic foot ulcers (DFUs). These tissues include allogenic dermis as well as xenograft dermis, pericardium, and small intestine submucosa. While all of these tissues show promise for healing DFUs, dermal-derived matrices have shown considerable potential.
