Metabolic Profiling of Immune Responses in Immune-mediated Diseases
Primary ImmunodeficiencyPsoriasis2 moreBackground: The immune system is the part of the body that fights infection. Some people have immune deficiencies that cause skin rashes, make them get sick often with infections, or make it difficult for their skin to heal. Researchers want to learn more to better treat conditions that affect immune response. Objective: To learn about how the immune system and skin healing are related to each other. Eligibility: People ages 18-75 with primary immune deficiency, eczema, or psoriasis. Healthy volunteers are also needed. Design: Participants will be screened with a medical and medicine history and a physical exam. They may take a pregnancy test. Participants will discuss the medicines or supplements they take as well as skin products they use, such as soaps and lotions. Participants will have up to 4 skin biopsies taken from the forearm. A needle will inject an anesthetic into the skin where the biopsy will be done. A sharp tool that looks like a tiny cookie cutter will be used to remove a round plug of skin a bit smaller than the tip of a pencil. Participants will give at least 1 blood sample. Participants may have optional skin swab collection. A cotton swab will be used to swab the skin on the arm. Participants may have optional skin tape collection. A sticky strip of tape will be placed on the arm and then removed. Participants may give leftover samples taken as part of their regular medical care. Participation will last for about 4 days. Participants will have 2 visits that each last about 1 hour. They may be asked to repeat the study in the future.
10 Year Registry of Children (Ages 2-17 Years) With Eczema That Have Used Pimecrolimus
Atopic DermatitisThis study will examine the risk of systemic malignancies in pediatric patients with atopic dermatitis exposed to Elidel 1% cream.
An Observational Retrospective Cohort Study Being Conducted in Women With Atopic Dermatitis (AD)...
Adverse Pregnancy OutcomesAtopic DermatitisThe objective of this study is to describe and compare the incidence of adverse pregnancy outcomes (spontaneous abortion/miscarriage, stillbirth) and prevalence of infant outcomes (major congenital malformations [MCMs], small for gestational age [SGA]) in women with AD who are treated with dupilumab during pregnancy relative to women with AD who are not treated with dupilumab during pregnancy.

Insulin Resistance in Atopic Dermatitis Patients
Atopic DermatitisThe aim of the study is to determine the relationship between insulin resistance and disease duration and severity of atopic dermatitis.
Studies of Skin Microbes in Healthy People and in People With Skin Conditions
Atopic DermatitisEczema1 moreThis 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: Medical family and medication history Skin examination Blood tests (research blood as well as serum IgE, and complete blood count) Skin samples to analyze microbes. Samples are obtained by the following methods: swabbing the skin with a cotton swab; scraping (scratching) the skin gently with a blade to remove only the outermost skin layers; and, only in adults, biopsy (surgical removal) of a small skin sample less than 1/4-inch (5 mm) in diameter. Nose swabs to analyze microbes. Patients with eczema may have photographs of their skin taken to help monitor the skin rashes. 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.
Extrinsic and Intrinsic Factors in Atopic Dermatitis Upon Systemic Immune Modulation
Atopic DermatitisCurrently, patients with moderate to severe atopic dermatitis are treated with dupilumab if unresponsive to topical treatment. However, not all patients who suffer from atopic dermatitis respond similarly to this treatment. Pattern recognition of immune cells (PRI) is an efficient method to screen patients to allow a more personalized therapy. The main aim of this scientific explorative study is to unravel the changes in peripheral blood immune cell compositions in patients with atopic eczema undergoing dupilumab treatment. This allows the identification of phenotypes of treatment responders and non-responders and possible approaches of treatment modifications for non-responders.
A Prospective Sample Collection Study Using Non-invasive Methods to Investigate Biomarkers in AD...
Atopic DermatitisThis is a prospective, multicenter, sample collection study using DermTech's non-invasive skin collection kits to evaluate genomic biomarkers and microbiome information from pediatric and adult subjects with atopic dermatitis(AD). Samples collected will be analyzed to detect gene signatures and microbiome populations associated with AD and sub-populations of AD.
Assessing SleeP IN Infants With Atopic Dermatitis by Longitudinal Evaluation
Atopic DermatitisSleep DisturbanceThe SPINDLE study will examine sleep in infants with atopic dermatitis by serial assessment over the first year of life, in comparison to infants without atopic dermatitis. Sleep will be assessed using electroencephalography, actigraphy, and sleep questionnaires.
Monitoring Pregnancy and Infant Outcomes Following Tralokinumab Exposure During Pregnancy in the...
Atopic DermatitisEczemaThe goal of this observational study is to learn about exposure to tralokinumab during pregnancy, as well as atopic dermatitis (AD) during pregnancy. The main question the study aims to answer is whether pregnant people who have been exposed to tralokinumab during pregnancy experience any differences in pregnancy and infant outcomes compared to women with atopic dermatitis who have not been exposed to tralokinumab during pregnancy. Participants are not required to take tralokinumab during the study. Participants will be asked to: Complete 1-3 phone interviews during pregnancy and 1-2 phone interviews after delivery Release medical records for pregnancy and for their child Complete an online survey about their baby's development at 4 months and 12 months of age May be asked to have a study doctor examine their child All information is collected remotely, and no visits to the study site are required.
