Atopic dermatitis in older patients: particular points.

Area of Science:

• Dermatology
• Immunology
• Allergology

Background:

• Atopic dermatitis (AD) affects 1-3% of adults globally, appearing as adult-onset or persistent childhood AD.
• Adult AD significantly impacts quality of life, including sexual and occupational aspects, with characteristic affected areas like flexures, head, and hands.
• Elderly adults may experience eczematous erythroderma, and intrinsic eczema subtypes occur in 5-15% of cases.

Purpose of the Study:

• To review and compare the distinct characteristics of atopic dermatitis (AD) in adults with those observed in childhood.
• To highlight the prevalence, clinical presentation, and etiological factors of adult AD.
• To identify specific challenges and research needs for managing AD in the adult population.

Main Methods:

• Literature review focusing on epidemiological data, clinical presentations, and immunological findings in adult atopic dermatitis.
• Comparison of adult AD characteristics with established data from childhood AD.
• Analysis of factors such as aeroallergen sensitivity, microbial colonization, and occupational exposures.

Main Results:

• Adult AD commonly affects flexural areas, head/neck, and hands; elderly adults may present with eczematous erythroderma.
• A majority of adult AD patients show sensitivity to aeroallergens like dust mites.
• Adult skin exhibits higher colonization by Malassezia yeasts compared to children, with specific sensitization noted in head-and-neck eczema.

Conclusions:

• Significant differences exist between adult and childhood atopic dermatitis, necessitating tailored research and clinical approaches.
• Increased prevalence of adult AD warrants further clinical and immunological studies, particularly in older adult populations.
• Understanding adult-specific triggers and management strategies is essential for improving patient outcomes and quality of life.
