Itching for New Help for Eczema: Recently Identified Immune Cells Possible Therapeutic Target, University of Pennsylvania Study

The increasing incidence of allergic skin diseases, and the accompanying economic burden and heightened risk of developing other allergic conditions, have spurred researchers to look for better ways to control these immune system-based disorders. Atopic dermatitis, more commonly called eczema, now affects 10 to 20 percent of children in the United States and direct health-care costs exceed $3 billion, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases.What's more, up to 50 percent of children with atopic dermatitis will develop other allergic diseases, including asthma, a phenomenon termed the "allergic march," the gradual acquisition of co-existing allergic diseases.
