Atopic dermatitis (AD), also called eczema, makes skin dry, red, and itchy. People with AD are more
likely to get a food allergy than people without AD. But some food allergy tests are not always
accurate in people with AD. Researchers want to study if people with AD and high total IgE levels are
truly allergic to milk and/or peanuts with the aim of improving the ways doctors test for food allergy
in people with AD.

What Does the Study Involve?

In this study, participants aged 3-21 years (n = 175) with elevated total serum IgE levels and a history
of AD will receive a comprehensive allergy evaluation including food allergy testing, a plan and
medications to treat their AD, and a nutritional assessment and counseling sessions with a dietitian.
Additionally, participants will undergo open feedings and/or double-blind, placebo-controlled food
challenges (DBPCFCs) to peanuts and/or milk. The challenges will conclusively determine if the
participant is truly allergic to milk and/or peanuts and whether they can safely reintroduce the food(s)
into their diet or if they need to continue avoiding the food(s). The challenges are done in an inpatient
unit at the NIH Clinical Center with staff who have expertise in performing food challenges.
