From the Guidelines
Mirragen and ACell are both effective advanced wound care products, but the most recent and highest quality study 1 suggests that the choice between them should be based on wound type, location, and patient-specific factors.
Key Differences
- Mirragen is a glass-fiber-based product that contains borate bioactive glass fibers which gradually dissolve and release elements that stimulate cell growth and angiogenesis.
- ACell, on the other hand, is derived from porcine urinary bladder matrix and contains intact extracellular matrix components that promote site-specific tissue remodeling rather than scar formation.
Clinical Applications
- Mirragen is particularly effective for chronic wounds like diabetic ulcers and provides a scaffold that mimics the extracellular matrix.
- ACell is often used for complex wounds, burns, and surgical applications.
Considerations for Use
- Both products support moist wound healing environments, but Mirragen may be preferred for wounds requiring bioactive stimulation and mineral delivery, whereas ACell excels in promoting constructive remodeling with minimal scarring.
- The choice between these products should consider cost differences as well.
- Both require proper wound bed preparation before application and should be part of a comprehensive wound care approach that addresses underlying causes of poor healing, as emphasized by studies on debridement and wound care 1.
Evidence-Based Recommendation
- Given the limited high-quality evidence on the specific comparison of Mirragen and ACell, the decision should prioritize patient-specific factors, wound characteristics, and the comprehensive approach to wound care 1.
From the Research
Comparison of Mirragen and ACell
- Mirragen is a resorbable glass microfiber matrix used in wound healing, as studied in 2.
- ACell is not directly mentioned in the provided studies, but its comparison to Mirragen can be inferred in the context of wound healing and tissue repair.
- The study 2 shows that Mirragen, when used in conjunction with standard diabetic foot care, significantly improved wound healing compared to standard of care alone, with 70% of wounds healed at 12 weeks.
Wound Healing and Tissue Repair
- The effectiveness of wound dressings in promoting wound healing is discussed in 3, which evaluated the performance of polyabsorbent fibre dressings in a large prospective observational study.
- The study 3 found that the dressings were efficient in removing sloughy tissue and promoting wound healing, regardless of wound type or infection status.
- However, there is no direct comparison between Mirragen and ACell in the provided studies, making it difficult to determine their relative effectiveness in wound healing and tissue repair.
Treatment of Chronic Wounds
- The treatment of chronic wounds is discussed in 4, which provides a consensus on the best treatment approaches for chronic wounds.
- The study 5 highlights the importance of considering the microbiome of chronic wounds, as certain microbial predictors can influence healing outcomes.
- While these studies provide valuable insights into wound healing and tissue repair, they do not directly compare Mirragen and ACell, and therefore do not provide a clear answer to the question of how they compare in terms of wound healing and tissue repair 2, 3, 4, 5, 6.
