Primary purpose: TREATMENT

Brief summary: This is a multi-center, longitudinal study which will characterize the gene expression profiles and transcriptomic endotypes that underlie mild and moderate-severe Atopic dermatitis (AD) and will determine changes in these expression patterns and endotypes in response to standard-of-care treatment. Participants will complete up to ten scheduled study visits with assessment of topical steroid response and dupilumab response (if uncontrolled with topical steroids). Skin samples will be collected at all study visits to determine the gene expression profiles and transcriptomic endotypes that underlie mild vs. moderate-severe AD disease. The investigators will also evaluate the lipidomic, metabolomic, proteomic, and microbiome profiles of AD skin endotypes associated with mild and moderate-severe AD disease. Non-AD participants will serve as a control population.

The primary objective of this study is to determine if the type 2-high non-lesional skin (skin tape) endotype is associated with current mild versus moderate-severe AD disease.

    DNAD Participants:
12. DNAD participants must have active lesions on the upper or lower extremities or trunk of sufficient size and in the required locations, as specified in the study manual of procedures (MOP), for specimen collection at the Baseline Assessment and Steroid Initiation (Day 7) Visits.

3. Weight less than 15 kg
4. Known systemic hypersensitivity to any of the excipients of the study treatments (Vanicream (TM), hydrocortisone, triamcinolone, or dupilumab)
5. Have any skin disease other than Atopic dermatitis (AD) that might compromise the stratum corneum barrier (e.g., bullous diseases, psoriasis, cutaneous T cell lymphoma \[also called Mycosis Fungoides or Sezary syndrome\], dermatitis herpetiformis, Hailey-Hailey, or Darier's disease)

7. Known history of human immunodeficiency virus (HIV) infection
8. Ocular disorder that in the opinion of the investigator could adversely affect the individual's risk for study participation. Examples include, but are not limited to, individuals with a history of or active case of herpes keratitis; Sjogren's Syndrome, Keratoconjunctivitis Sicca, or Dry Eye Syndrome that require daily use of supplemental lubrication; or individuals with ocular conditions that require the regular use of ocular corticosteroids or cyclosporine

12. History of alcohol or drug abuse within 2 years before the Screening Visit
13. History of keloid formation (exclusionary for adult participants only)
14. History of hypersensitivity to local anesthetics (e.g., lidocaine or Novocain), bleeding disorders, or treatment with anticoagulants or other conditions in adult participants that would make the biopsy procedure inadvisable
