The role of the skin microbiome in atopic dermatitis

Atopic dermatitis (AD) is a common inflammatory skin disease associated with significant medical burden, affecting 15-20% of children and 1-3% of adults worldwide.1 The prevalence of AD has increased by 2-3 folds during the past decade in Western countries. While the cause of this increase remains unknown, meta-analyses have indicated that the risk of AD is lower when associated with potentially protective environmental factors during childhood such as three or more siblings, day care, pet ownership and farm residence.
