Exosomes derived from human adipose tissue-derived mesenchymal stem cells for the treatment of dupilumab-related facial redness in patients with atopic dermatitis: A report of two cases

초록

Background Atopic dermatitis is a chronic, pruritic, and inflammatory dermatosis that affects approximately 20% of children and 10% of adults worldwide. Dupilumab facial redness is gaining attention as additional cases are coming to light in the medical literature. Objectives and methods Exosomes are nano-sized vesicles that are constantly released by almost all cells. They can travel between cells and transport their cargo (lipids, proteins, and nucleic acids), making them a possible cell-free therapeutic option for various diseases. Herein, we investigated whether topical application of human adipose tissue-derived mesenchymal stem cell-derived exosomes could reduce dupilumab facial redness in patients with severe atopic dermatitis. Results Two patients with atopic dermatitis and refractory dupilumab facial redness were successfully treated with electroporation-assisted topical application of human adipose tissue-derived mesenchymal stem cell-derived exosomes. Six repeated sessions of treatment, with an interval of 1 week between each session, led to marked improvement in erythematous facial lesions. Conclusions We suggest that human adipose tissue-derived mesenchymal stem cell-derived exosomes may serve as an effective agent in the management of dupilumab facial redness. However, further controlled studies with a larger number of patients are necessary to confirm the efficacy and safety of this agent, as well as the optimal treatment protocol.
