Low-level laser therapy for the treatment of epidermolysis bullosa: A case report

Innovations in the Treatment of Dystrophic Epidermolysis Bullosa (DEB): Current Landscape and Prospects

Dystrophic epidermolysis bullosa (DEB) is one of the major types of EB, a rare hereditary group of trauma-induced blistering skin disorders. DEB is caused by inherited pathogenic variants in the COL7A1 gene, which encodes type VII collagen, the major component of anchoring fibrils which maintain adhesion between the outer epidermis and underlying dermis. DEB can be subclassified into dominant (DDEB) and recessive (RDEB) forms. Generally, DDEB has a milder phenotype, while RDEB patients often have more extensive blistering, chronic inflammation, skin fibrosis, and a propensity for squamous cell carcinoma development, collectively impacting on daily activities and life expectancy. At present, best practice treatments are mostly supportive, and thus there is a considerable burden of disease with unmet therapeutic need. Over the last 20 years, considerable translational research efforts have focused on either trying to cure DEB by direct correction of the COL7A1 gene pathology, or by modifying secondary inflammation to lessen phenotypic severity and improve patient symptoms such as poor wound healing, itch, and pain. In this review, we provide an overview and update on various therapeutic innovations for DEB, including gene therapy, cell-based therapy, protein therapy, and disease-modifying and symptomatic control agents. We outline the progress and challenges for each treatment modality and identify likely prospects for future clinical impact.

Improved erythema and decreased blister formation in dominant dystrophic epidermolysis bullosa following treatment with pulsed dye laser

Dominant dystrophic epidermolysis bullosa (DDEB), an inherited disorder due to type VII collagen mutations, is characterized by blisters and erosions that heal with scarring, atrophy, and milia. There is no established role for laser in the management of patients with DDEB. Pulsed dye laser (PDL) is most often used to target vascular skin lesions. We describe a patient with DDEB with marked improvement in erythema as well as fewer and less symptomatic episodes of blistering following treatment with PDL.

Recessive dystrophic epidermolysis bullosa: a case study

The article presents a description of an inherited disease, recessive dystrophic epidermolysis bullosa, in a patient aged 19. The treatment with antibacterial, antiseptic, antianemic and wound-healing drugs, non-adhesive surgical dressings and lowintensive laser light substantially improved the patient’s condition.

Low-level laser therapy on the treatment of oral and cutaneous pemphigus vulgaris: case report

Pemphigus vulgaris is a chronic autoimmune mucocutaneous disease that initially is manifested by painful intraoral erosions and ulcers which spread to other mucosa and the skin, generally more than 5 months after oral lesion manifestation. The treatment consists of prednisone alone or in combination with an immunosuppressive agent, and the clinical response is perceived within 2 to 4 weeks. Low-level laser therapy has been effective in accelerating the healing of injured tissue, thus inducing cell proliferation and increasing ATP, nucleic acid, and collagen synthesis. We reported two cases of pemphigus vulgaris that received systemic treatment associated with low-level laser therapy for oral and cutaneous lesions. We observed prompt analgesic effect in oral lesions and accelerated healing of oral and cutaneous wounds. Therefore, the present report suggests LLLT as a noninvasive technique that should be considered as an adjuvant therapy in oral and skin disorders in patients with PV.
