Evaluating Skin Barrier Dysfunction in Infants at High Risk of Atopy
Study Details
Study Description
Brief Summary
It is hypothesized that food allergy is preceded by atopic dermatitis (AD), due to a disruption of skin barrier which can predispose one to food sensitization through the skin. The central hypothesis is that increased transepidermal water loss (TEWL) assessment and skin tape strip analysis (STS) of lipid and filaggrin breakdown products will be predictive markers for the development of AD. Additionally, the associated changes in TEWL and STS will further improve the identification of infants at risk of early food sensitization, compared to family history alone.

Other: High Risk Atopic Infants Infants, who are at high risk of atopy, which will be determined by a validated questionnaire, will be enrolled. Infants will undergo skin tape stripping (STS), transepidermal water loss assessment (TEWL), bacterial swabs, and parental questionnaires at each visit (3 visits total). At the latter 2 visits, infants will also undergo skin prick testing to evaluate for food sensitization. |
Other: Evaluating atopy in infants
This study does not have an intervention. There is the evaluation of the predictive value of TEWL and STS in atopic infants at risk of developing eczema and TEWL and STS in parents of infants.

Other: Atopic Adults Parents of infants enrolled in the study will undergo skin tape stripping (STS), transepidermal water loss assessment (TEWL), and complete questionnaires at the first visit. |
Other: Evaluating TEWL and STS in adults
This study does not have an intervention. There is the evaluation of the predictive value of TEWL and STS in atopic infants at risk of developing eczema and TEWL and STS in parents of infants.

Outcome Measures
Primary Outcome Measures
- Serial Transepidermal Water Loss (TEWL) [12 months]
Skin Barrier Assessment measured through serial transepidermal water loss (TEWL) in grams of water/meters-squared/hour
Secondary Outcome Measures
- Skin Tape Stripping (STS) and Filaggrin(FLG) breakdown products [Up to 12 months]
Risk of atopic dermatitis as evaluated through FLG breakdown products, lipid composition in the skin, and skin ape strip samples
- Skin prick testing to milk, egg, and peanut [12 months]
Food Allergen Sensitization measured by positive skin prick testing to milk, egg, and peanut measured as positive or negative
Eligibility Criteria
Criteria
Inclusion Criteria:
- Women with physician confirmed pregnancy at a gestational age of ≥ 34 weeks. Infants at high risk for atopy will have one or both parents affected by an allergic disease. Infants at low risk for atopy will have no parent or sibling affected by allergic disease. Biologic parent(s) of infants at high risk of atopy will also be enrolled in the study.
Exclusion Criteria:
- Pregnancy loss or delivery prior to a gestational age of ≥ 34 weeks, a history of substance or alcohol abuse, psychiatric and developmental co-morbidities that would render a subject unable to provide informed consent or perform study-related procedures, AIDS and HIV infection, or a fetus with chromosomal or congenital abnormalities.
