Bleach baths provide temporary control of eczema.[1] Ciprofloxacin is an allergen that may cause contact dermatitis, symptoms of which are indistinguishable from eczema.[2] Filaggrin mutations are associated with atopic eczema and may contribute to the excessive dryness of the skin and the loss of the barrier function of normal skin.[3] It may be possible that the filaggrin mutations and the loss of the normal skin barrier expose crevices that make it possible for Staphylococcus aureus to colonize the skin.[4] Atopic eczema is often associated with genetic defects in genes that control allergic responses. Thus, some investigators have proposed that atopic eczema is an allergic response to increased Staphylococcus aureus colonization of the skin.[5] A hallmark indicator of atopic eczema is a positive “wheal-and-flare” reaction to a skin test of S. aureus antigens. In addition, several studies have documented that an IgE-mediated response to S. aureus is present in people with atopic eczema.[6][7]
