Abstract:
Loss-of-function FLG mutation (FLGmut) carriers are at an increased risk of developing atopic dermatitis (AD), characterized by earlier onset and more severe disease. AD is driven by a complex interplay between skin barrier function, TH2 and TH2-dominant immune dysregulation, and dysbiosis. Results from the Short-Term Topical Application for Prevention of Atopic Dermatitis study suggest 2 early initiating AD pathogenetic pathways: an FLGmut-related skin barrier deficiency pathway and an immune function-related inflammatory pathway. The Short-Term Topical Application for Prevention of Atopic Dermatitis study suggested that early preventative intervention with specialized emollients for barrier function augmentation may benefit newborns with FLGmut. This requires early identification of FLGmut carriers, for which noninvasive Raman spectroscopic determination of natural moisturizing factor (NMF) levels in the stratum corneum of the thenar eminence provides a surrogate marker.
