Why are patients with atopic dermatitis prone to infection?

Factors that contribute to the increased infections in atopic dermatitis (AD) are skin barrier defects, suppression of cutaneous innate immunity by type 2 inflammation, Staphylococcus aureus colonization, and cutaneous dysbiosis. Skin infections in AD increase the risk of life-threatening systemic infections.
