Atopic Dermatitis: Disease Background and Risk Factors

Area of Science:

• Dermatology
• Genetics
• Allergology

Background:

• Atopic dermatitis (AD) is a complex skin condition with multiple known risk factors.
• Genetic factors, particularly filaggrin (FLG) gene mutations, are significant contributors to AD development.
• A family history of atopic or allergic diseases increases an individual's risk for developing AD.

Purpose of the Study:

• To comprehensively review the established and emerging risk factors for atopic dermatitis.
• To explore the common comorbidities associated with atopic dermatitis.
• To provide an overview of the genetic and environmental influences on AD pathogenesis.

Main Methods:

• Literature review of genetic studies on filaggrin (FLG) and atopic dermatitis (AD).
• Analysis of epidemiological data on family history and AD prevalence.
• Compilation of reported comorbidities associated with AD, including allergic, infectious, and neuropsychiatric conditions.

Main Results:

• Filaggrin (FLG) gene mutations are a primary genetic risk factor for atopic dermatitis (AD).
• Positive family history of atopic diseases significantly elevates AD risk.
• AD is associated with an increased incidence of asthma, allergic rhinitis, food allergies, skin infections, ADHD, ASD, and poorer sleep quality.

Conclusions:

• Understanding the multifaceted risk factors for atopic dermatitis is crucial for early diagnosis and intervention.
• The 'atopic march' highlights the progression from AD to other allergic diseases.
• Associated comorbidities underscore the systemic impact of AD, affecting physical and mental health.
