Antimicrobial Response to Oral Vitamin D3 in Patients with Psoriasis (CATH 03)

Atopic Dermatitis (AD) is a skin disorder in which people often have swelling and skin infection. People with this disease cannot receive the smallpox vaccine because it could cause them to have a fatal reaction known as eczema vaccinatum (EV). AD subjects have a lack of antimicrobial peptides (AMPs) under inflammatory conditions. This is a substudy to the ADVN Vitamin D3 study (ADVN CATH 03).
