National Institute of Allergy and Infectious Diseases (NIAID)
  Purpose
People with atopic dermatitis (AD), or eczema, are susceptible to skin infections and inflammations. Some individuals with AD develop a condition known as eczema herpeticum (EH) following exposure to the herpes simplex virus (HSV). The purpose of this study is to identify the genetic determinants that lead people with AD to develop EH and similar conditions caused by other viruses.

Condition
Atopic Dermatitis

Study Type: Observational
Study Design: Time Perspective: Cross-Sectional

Further study details as provided by National Institute of Allergy and Infectious Diseases (NIAID):

Primary Outcome Measures:
  • Identification of variants/haplotypes in EH-associated genes and characterization of frequencies of variants in priority candidate genes for EH [ Time Frame: Throughout Study ]

Secondary Outcome Measures:
  • Identification and prioritization of novel genes induced in response to viral infection (HSV/Vaccinia and MCV) in AD participants and relevant control groups [ Time Frame: Throughout Study ]

Biospecimen Retention:   Samples With DNA
Skin scrapings and blood collection may occur

Enrollment: 900
Study Start Date: May 2006
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts
Eczema Herpeticum (EH)
Participants with AD who currently have or have had EH
Non-EH
Participants with AD who do not have and have never had EH
Healthy Controls
Healthy participants without a history of AD

Detailed Description:

AD is a chronic inflammatory skin disorder characterized by recurrent viral skin infections. However, people with AD do not all develop the same infections. For example, some people with AD who receive the smallpox vaccine develop a life-threatening condition known as eczema vaccinatum (EV). This study focuses on individuals with AD who also have a history of eczema herpeticum (ADEH+), a condition similar to EV. It is unlikely that the differences in the development of skin infections are due to differences in viral exposure, and instead due to differences in each individual's response to viruses. The purpose of this study is to determine the genetic pathways which are responsible for the development of viral skin infections in people with AD.

Participants in this study will also be enrolled in the ADVN Biomarker Registry Study. There will be only one clinical visit for this study at which blood and/or skin samples may be collected. The samples will then have high-throughput genotyping to define genetic markers in individuals susceptible to viral infections.
