In the UK, around 120,000 people visit A&E annually due to burn injuries, with 72% resulting in hypertrophic scarring, a type of raised scar that forms within the boundaries of the original wound due to excessive collagen production during healing. While traditional wound dressings effectively promote healing, there’s growing interest in innovative approaches that address post-burn scarring more effectively.
What We Know:
Traditional dressings help close and heal wounds by providing hydration and antimicrobial protection, but they aren’t designed to prevent or treat post-burn scarring. Burns disrupt the skin’s microbial balance, favouring heat-loving microbes like Aeribacillus, Caldalkalibacillus and Nesterenkonia while reducing beneficial bacteria such as Cutibacterium, Staphylococci and Corynebacteria. Increased levels of Corynebacterium are linked to higher infection risks, whereas Staphylococci and Cutibacterium are associated with lower infection rates post-burn (Yang et al., 2024).
Despite reduced bacterial richness at the genus level, burn patients exhibit increased microbial community diversity and evenness. This altered microbial landscape, marked by a lower overall bacterial burden and an overgrowth of Staphylococcus species, highlights a persistent dysbiotic state in the skin microbiota during the subacute phase of wound healing (Liu et al., 2018).
Industry Impact and Potential:
@Healome Therapeutics has developed a groundbreaking bioactive skin dressing technology, recently cleared by the @Medicines and Healthcare products Regulatory Agency (MHRA) for a phase I trial aimed at reducing scarring. The trial, conducted at Queen Elizabeth Hospital in Birmingham, UK, involves 25 patients with burns covering 3-20% of their body surface.
Healome’s innovative dressing is a clear film that not only offers the benefits of traditional wound dressings but also incorporates synthetic human-derived decorin protein, which plays a critical role in wound healing. This protein reduces the inflammatory response and regulates the wound’s microenvironment. Early research suggests that this approach may reduce fibrosis and promote tissue regeneration, offering new hope for scar management in burn patients.
Products like Healome’s dressing showcase the exciting potential of using the microbiome and skin environment to enhance wound healing, paving the way for future innovations in burn care.
