World-first burn treatment shows ‘remarkable’ results in Canadian patient

Burn specialists in Ontario have performed a groundbreaking medical procedure, using a novel biological therapy known as exosomes to treat a young woman severely injured in a house fire.

The treatment, a world-first for burn patients, involved injecting exosomes, tiny particles released by cells that help coordinate healing and reduce inflammation, into the injured areas of an 18-year-old Western University student, Kaitlin Jeffrey. The goal was to speed up the healing process and minimize the need for skin grafts, which can result in scarring and uneven skin texture.

My vision for Kaitlin was to avoid skin graft surgery to her face and neck at any cost.

Exosomes have been a subject of burn research for years, showing promise in other types of wound healing, but this marks their first application in human burn cases. Dr. Marc Jeschke, a burn surgeon at Hamilton Health Sciences and professor at McMaster University, led the procedure after receiving approval from Health Canada on compassionate grounds. He expressed a strong desire to avoid skin graft surgery for Jeffrey's face and neck.

You can do the best graft on the planet, but you won’t return the skin to normal.

Jeffrey underwent two treatments using approximately one trillion exosomes sourced from the United States. Doctors reported that she healed more quickly and achieved better results compared to another student injured in the same fire who did not receive the exosome therapy. Jeschke noted that even the best skin grafts cannot fully restore normal skin, especially on the face, which can be particularly challenging for younger patients.

Jeffrey described the outcome as "honestly a miracle," highlighting the positive impact on her recovery, particularly for her face, and aiding her psychological healing. Hamilton Health Sciences conducted the procedure at its regional burn program at Hamilton General Hospital. While further research is needed, Jeschke hopes this exosome treatment could eventually become a standard of care in Canada, a sentiment echoed by Jeffrey and her family.
