Association between atopic dermatitis and thyroid disease among U.S. adults in the 2001-2006 National Health and Nutrition Examination Survey

To the Editor: Atopic dermatitis (AD) is a common and chronic inflammatory dermatological condition that affects the daily life of individuals in various ways. Many studies have discussed the numerous autoimmune conditions that are potentially associated with AD.1 Recent research has suggested that the underlying pathophysiology of AD may contribute to the development of autoimmunity.2 In addition, our group has reported that psoriasis is associated with thyroid dysfunction.3 In 2012, Pedullà et al4 reported a significant association between AD and autoimmune thyroid disease in children from Naples, Italy.
