Efficacy of PDT in vulvar LS treatment based on immunohistochemical analysis of CD3, CD4, CD8, CD57, Granzyme B and Fascin expression

Abstract: 155 SummaryBackground: Lichen sclerosus (LS) is an immune-mediated chronic dermatosis of perimenopausal women. Inflammatory infiltration has been suggested as a potential cause of LS changes in epidermis and dermis. Photodynamic therapy (PDT) is a specific noninvasive treatment based on detection and subsequent selective destruction of LS-affected tissues that are marked by a photosensitizer. Immunomodulatory and cytotoxic effects of PDT are responsible for inducing several immunologic reactions which leads to… Show more

“…Less commonly used measures of disease severity included the description of histological features such as epidermal atrophy, hyperkeratosis, and dermal inflammation 14 , 25 , 48 53 and the measurement of various inflammatory marks with immunohistochemical staining. 14 , 20 , 21 , 26 , 46 , 48 , 51 , 54 58 Finally, some studies focused on the quality-of-life effects of this disease as well as interference with sexual functioning. 18 , 22 , 35 , 48 , 59 , 60 …”

“…There is no dosimetric protocol established for the treatment of VLS with PDT, nor with PBM. According to the literature, energy densities range from 9 to 150 J/cm 2 and power densities from 40 to 700 mW/cm 2 [ 16 21 ], without mentioning the studies that do not report the dosimetry used [ 22 , 23 ].…”

“…There are few references in the literature about the action of PDT in vulvar lichen sclerosus [ 16 20 , 22 , 23 ], and till now there is no reference concerning PBM, although the anti-inflammatory and healing effects of PBM are documented in various medical and biological applications [ 24 ]. It is hoped that a prospective clinical study would contribute to more effective action in the control of this chronic skin disease, and possible understanding the mechanisms of action of these treatments.…”
