Medical Honey for Wound Treatment in Intensive Care. (MICARéa) Randomized, Controlled, Single-center Pilot Study.

Wound management is a real public health issue in France. To date, a wide range of devices exists to treat these wounds, depending on their nature and stage of evolution. Honey has been proposed for the care of wounds and is effective in reducing the surface of wounds and the pain perceived by patients. Inanition, its use is very simple compared to usual care, requiring different types of dressing accross time. In the intensive care unit, patients are prone to suffering or developing numerous types of wound, but the interest of honey has not been investigated yet. We propose a prospective, monocentric, randomized, single-blind, controlled clinical trial to assess the efficacy of managing acute cutaneous wounds with honey (Activon®) compared with standard care, in intensive care patients. The primary endpoint is the percentage of wound surface area reduction measured at 15 days from inclusion.

Randomized Controlled Trial on the Efficacy and Safety of Xiang Lei Ointment in Diabetic-related Ulcer Management

Diabetes is one of the major chronic diseases. Diabetic ulcers are important adverse outcomes of diabetes. Approximately 80% of lower - limb amputations are caused by diabetic foot ulcers, which are the main causes of disability and death among patients. Moreover, it places a huge burden on the medical insurance system. Currently, there are western medicine treatment guidelines for diabetic foot, yet the clinical efficacy is less than satisfactory. The amputation rate caused by diabetic foot ulcers continues to rise every year. There is an urgent clinical need for novel and effective intervention measures to address this disease. Macrophages are important cells involved in the inflammatory and proliferative phases of wounds, playing a crucial role in wound repair and reconstruction. Diabetes can cause wounds to remain in the pro - inflammatory stage continuously, leading to the aggregation of M1 macrophages and preventing their timely transformation into the pro - proliferative and repair stage. As a result, wounds exhibit persistent chronic inflammation and delayed tissue proliferation or remodeling. Xianglei Tangzu Ointment is a natural medicine approved for marketing by the National Medical Products Administration in November 2023. Its ingredients include Pogostemon cablin extract and asiaticoside. Research shows that the plant components in Xianglei Tangzu Ointment can promote the transformation of M1 macrophages into M2 macrophages, thereby reducing the inflammatory response and accelerating the proliferative repair of diabetic wounds. It has achieved certain curative effects in the clinical treatment of promoting wound healing. In order to use Xianglei Tangzu Ointment more precisely, accumulate clinical evidence - based medicine evidence, and explore the effectiveness and safety of Xianglei Tangzu Ointment in treating diabetic ulcers under the guidance of the chronic wound staging theory, clinical evidence - based medicine evidence needs to be obtained.

An Exploratory Research on the Efficacy and Safety of Antibacterial Absorbable Dressing in Chronic Non-healing Wounds

Antimicrobial absorbable wound dressing is a novel polyester-based degradable dressing. Previous preclinical studies have demonstrated promising efficacy, with a 3-week wound area reduction rate of 63.53% in large animal models, outperforming foreign counterparts (49.47%), without significant adverse reactions observed during application. Toxicological risk assessment confirms acceptability, and small animal model studies show no abnormalities in toxicity or sensitization. However, current evidence lacks clinical validation, particularly regarding efficacy and safety in chronic non-healing wounds. This study integrates modern clinical evaluation methods with chronic wound staging theory to systematically investigate the effectiveness and safety of antimicrobial absorbable wound repair materials in treating chronic non-healing wounds. The research aims to identify optimal indications and provide robust evidence for its clinical efficacy and safety.

Effect of Ev.FV on Wound Healing in Dystrophic Epidermolysis Bullosa

Epidermolysis bullosa (EB) is a hereditary disease of skin tissues that causes painful bleeding blisters in the skin and mucous membrane. The prevalence of this disease is 1 in 50,000. The severity of the disease varies depending on the type of disease and may even lead to death. This disease is caused by a genetic mutation in keratin or collagen, and its incidence is the same in all men and women of different human races. In these patients, the skin becomes extremely fragile and peels off with the slightest scratch. Many blisters are one of the most obvious symptoms of this disease. The possibility of skin cancer in people suffering from this disease is more than others. Nowadays, the preference of cell therapy methods is to use biological products produced by cells such as extracellular vesicles and mitochondria instead of stem cells. The use of Extracellular vesicles and engineered EVs as messenger carriers can introduce a new treatment method based on cell products for skin regeneration and as an alternative to cell therapy. Therefore, in this study, EV.FV will be applied topically to patients.

COMS for Chronic Ulcers Treatment

Chronic leg and foot ulcers are defined as wounds that fail to heal in a timely manner, typically persisting for over 4 to 8 weeks without substantial healing despite standard care. These ulcers often result from macro- and microvascular disorders, the most common being chronic venous insufficiency (CVI), alone or with peripheral artery disease (PAD) or microangiopathy. Despite different causes, chronic vascular-origin wounds share similar biological traits and require the same physiological processes for healing. Vascular issues hinder blood perfusion, reducing oxygen, nutrients, and growth factors, leading to decreased energy metabolism and impaired cell functions necessary for proliferation, extracellular matrix production, angiogenesis, and tissue regeneration. Reduced blood supply also limits leukocyte function, compromising the immune response and leading to persistent inflammation and infection. Consequently, these wounds cannot effectively heal, showing prolonged inflammation, persistent infections, and cellular senescence. Best practice wound care includes compression therapy and physical activity for venous ulcers, and angioplasty, surgery, or bypass for arterial ulcers. These treatments aim to improve blood flow, reduce venous stasis, and enhance venous return. Compression therapy and physical activity lower hydrostatic pressure in the lower limb, while angioplasty and surgery remove arterial blockages or create new blood flow routes. Recent studies highlight the role of mechano-sensitive (MS) ion channels in skin cell processes and their dysfunction in dermatological disorders. Magnetic stimulation can activate MS TRCP1 channels, enhancing mitochondrial respiration and mitochondriogenesis via the Ca2+/CalModulin(CaM)/NFAT/PGC-1α pathway. Ca2+-activated calmodulin also catalyzes nitric oxide (NO), promoting vasodilation and tissue perfusion. Bimodal red and near-infrared photobiomodulation can further increase mitochondrial respiration and ATP production by activating Cytochrome C oxidase and mitigating NO-induced downregulation. This synergistic mechanism of concurrent optical and magnetic stimulation (COMS) may amplify Ca2+ and NO-mediated processes like cell proliferation, migration, vasodilation, and angiogenesis while resolving inflammation. Thus, COMS may offer a promising therapy for chronic, inflammation-prone wounds. The effectiveness of COMS has yet to be validated in large-scale studies. This proposal aims to assess the impact of COMS therapy combined with standard care versus standard care alone on healing, wound closure, recurrence, pain, quality of life, economic outcomes, and device usability in patients with venous leg ulcers (VLU) and VLU associated with PAD in a large-scale multicentric randomized controlled trial.
