Abstract:

Statement of the Problem: The endocannabinoid system is ubiquitous throughout the human body and has recently been found to have a significant representation throughout the integumentary system, both cutaneous membranes and mucous membranes. Topical medical cannabis (TMC) based medicines are intrinsically lipophilic and contain both delta-9- tetrahydrocannabinols (THC) and cannabidiol (CBD) in varying proportions. Given that wound beds are largely lipophilic absorption of lipophilic agents, such as cannabinoids, is enhanced.

Methodology & Theoretical Orientation: A series of n=1 trials were initiated on a cohort of stalled recalcitrant wounds, composed of cases of greater than 12 months duration, were treated with TMC based medicines. All cases were previously afforded with all available evidence-based treatments that confirmed with local best practices and wound-bed preparation principles. Ten cases were studied for wound analgesia, ten cases for wound healing, and four cases for disease modulation. Etiologies represented within the cohort understudy included: pyoderma gangrenosum, leukocytoclastic vasculitis, cryoglobulinemia, antiphospholipid syndrome, sickle cell disease, Bowen’s disease, and squamous cell cancer. Clinically significant analgesia, wound healing, and disease was noted in all cases. The TMC medicines were applied directly applied to wound beds. TMC was very well tolerated and no adverse reactions were observed.

Conclusion & Significance: The highly positive results observed in a cohort of the most challenging recalcitrant cases provoke realistic interpolation that TMC based medicines may be effective for a broader context within wound management. The endocannabinoid system is a viable epigenetic target and platform for exploring therapeutic options for skin and wound conditions. Therapies based on topical medical cannabis that interact at the level of the endocannabinoid system have significant potential to improve the three main target outcomes in wound management, namely, wound analgesia, wound healing and disease modulation that includes antineoplastic action.
