|Brief Title||Studies of Skin Microbes in Healthy People and in People With Skin Conditions|
|Official Title||Studies of Skin Microflora in Healthy Individuals and Atopic Dermatitis Patients|
This study will examine microbes (e.g., bacteria, fungi, viruses) that live on human skin and how microbes contribute to health and disease. It will analyze healthy human skin and how the these microorganisms might change in patients with atopic dermatitis (AD), a skin condition also known as eczema.
Healthy volunteers, as well as patients with moderate to severe eczema (AD), between 2 and 40 years of age may be eligible for this study.
We also wish to enroll children and adults aged 2-40 who have been diagnosed with inherited immune disorders known as HIES (hyperimmunoglobulin-E syndrome), WAS (Wiskott-Aldrich syndrome), or DOCK8 immunodeficiency because they frequently have skin problems similar to AD.
Eligible participants undergo the following tests and procedures:
Participants may be contacted periodically for follow-up studies. Patients with atopic dermatitis may have additional skin samples collected to examine changes in the skin bacteria over time and during all of the stages of eczema. In addition, patients who have a flare of their eczema are asked to undergo a skin sample collection as soon as possible.

Inclusion Criteria for all groups
Must have a primary care professional who will continue standard of care/evaluation in tandem with the protocol to whom information and recommendations can be communicated.
Inclusion Criteria for Group 1: Healthy Volunteers
Adult males or females aged 18-50 at time of enrollment.
Inclusion Criteria for Group 2: AD patients
A. Confirmed diagnosis of AD (UK Working Party s Diagnostic Criteria)24
B. Moderate to severe AD SCORAD greater than or equal to 25(25)
C. Greater than or equal to 1 affected antecubital (or popliteal) fossae at time of enrollment to serve as a target site.
Inclusion Criteria for Group 3: Healthy (pediatric) Controls
A. Males or females 2 18 years of age.
Inclusion Criteria for Groups 4, 5, & 6: AD/HIES/WAS/DOCK8 patients
A. Must have mutation-proven diagnosis, with or without eczematous dermatitis.
Exclusion Criteria for all groups:
Exclusion Criteria specific for Group 2: AD patients
A. Unable to remain off systemic (oral) antibiotics or systemic (oral) steroids for at least 7 days prior to body site sampling. Unable to temporarily discontinue use of topical steroids or calcineurin inhibitors for 7 days to small areas of skin intended for sampling. (Topical therapies/emollients for AD may be continued to non-adjacent, nontarget sites.)
B. Underlying immunodeficiency, either as primary disease or secondary to treatment.
Exclusion Criteria specific for Groups 4, 5, & 6: HIES/WAS/DOCK8 patients:
A. Unable to remain off topical steroids and emollients for preferably 7 days but at least 24 hours prior to body site sampling.
Exclusion Criteria specific for Groups 1 & 3: Healthy Volunteers and Healthy (pediatric) Controls:
A. Underlying immunodeficiency, either as primary disease or secondary to treatment.
B. Other documented chronic dermatologic disease, such as AD or psoriasis that may interfere with evaluation of the cutaneous microbiome. Common transient conditions, such as acne, are permissible.
C. Subjects who provide direct healthcare or reside in healthcare facilities or in non-hospital settings such as assisted living facilities, homeless shelters, jails and prisons as well as subjects with frequent exposure to laboratory animals.
D. Subjects with asthma.
