Abstract :

Atopic dermatitis is a chronic, relapsing inflammatory skin disease characterized by skin barrier defects and the burden of itch. In order to increase patients´quality of life, emollient-based skin care is the basis of all treatments. We provide clinical and scientific evidence that tailored skin care adapted to the phases of atopic dermatitis is able to break the itch-scratch cyle in a targeted way. To investigate anti-pruritic pathways and mechanisms in atopic skin, we developped an innervated atopic 3-dimensional skin model allowing the investigation of the cross-talk between sensory nerve endings and atopic skin cells (Roggenkamp et al, JID 2013). In this model, atopic keratinocytes released elevated level of nerve growth factor (NGF) resulting in nerve fiber sprouting, enhanced release of the neuropeptide calcitonin-gene-related peptide (CGRP) and epidermal thickening. Consequently, the atopic innervated skin model resembled the atopic phenotype in vivo with hyperinniveration and epidermal hyperplasia. Further studies implied that theactivation of the cold receptor TRPM8 can modulate NGF expression in atopic skin cells. The menthol-derivative and TRPM8 activator Menthoxypropanediol (MPD) reduced NGF expression and consequently hyperinnervation in atopic skin models(Roggenkamp. et al, EXP DERM 2016). As hyperinnervation has been associated with itch in atopic dermatitis, these results mechanistically indicate anti-itch efficacy of MPD in vitro. a proof of concept study (randomized, double blind, vehicle controlled) demonstrated that the treatment with a cooling compound including TRPM8 agonist MPD reduces chronic pruritus in xerotic skin (Ständer et al, JEADV 2016). Theses results were confirmed in a investigator-blinded study to assess the efficacy of a water-in-oil emulsion containing anti-inflammtory licochalcone A, anti-bacterial 1,2-Decanediol, anti-itch active MPD demonstrating a reduction in the lesional severity and S.aureus colonization as well as improvement of the barrier function parameters in volunteers with mild to moderately severe AD (Angelova-Fischer et al., JEADV 2014). These results emphazise that application of clinical evidence-based pro-active skin care significantly improves atopic dermatitis patient´s quality of life.
