Biomarkers of Th2 polarity are predictive of staphylococcal colonization in subjects with atopic dermatitis.
Br J Dermatol. 2009 Jan;160(1):183-5
Authors: Warner JA, McGirt LY, Beck LA
BACKGROUND: Staphylococcal colonization of the skin is commonly observed in subjects with atopic dermatitis (AD) and correlates with disease severity. Little is known about whether the degree of T-helper 2 (Th2) polarity in these subjects can also affect the frequency of bacterial colonization in this disease. OBJECTIVES: To determine if there is a correlation between markers of Th2 polarity [serum total IgE, eosinophilia and presence of another atopic disease (allergic rhinitis)] and skin colonization with Staphylococcus aureus in subjects with AD. METHODS: A retrospective chart review was performed of an academic dermatology clinic focused on the treatment of AD with a single provider. RESULTS: Staphylococcus aureus colonization was more commonly observed in subjects with AD who had peripheral eosinophilia, elevated serum IgE levels, and/or a history of or active allergic rhinitis. CONCLUSIONS: Results suggest that Th2 polarity may enhance subjects' risk for bacterial colonization.
