Patients with a body mass index (BMI) less than 30 kg/m2 and a history of atopic dermatitis on long-term (greater than 6 months) treatment with dupilumab. Researchers will compare in vivo evaluations of insulin sensitivity in subjects on dupilumab vs subjects matched for similar weight and BMI, with atopic dermatitis, but without dupilumab therapy (phototherapy).
The purpose of this study is to better understand the interactions between the innate immune system, in particular eosinophils, their secreted cytokines (interleukin-4), and metabolism in human health and disease states such as obesity and insulin resistance.
