Exploring the skin microbiome in atopic dermatitis pathogenesis and disease modification.

Area of Science:

• Dermatology and Microbiology
• Immunology

Background:

• Atopic dermatitis (AD) involves a compromised skin barrier, influenced by genetic, chemical, immunologic, and microbial factors.
• Increased skin pH in AD promotes Staphylococcus aureus overgrowth, exacerbating skin barrier deficiencies and immune dysregulation.
• Commensal skin bacteria can inhibit S. aureus through quorum sensing, highlighting the microbiome's role in AD pathogenesis.

Purpose of the Study:

• To review current and emerging strategies for modulating the skin microbiome in atopic dermatitis.
• To explore therapeutic approaches targeting skin pH, microbial balance, and immune responses in AD.

Main Methods:

• Review of direct and indirect methods for targeting the skin microbiome.
• Discussion of pH modulation, UV treatment, prebiotics, probiotics, and postbiotics.
• Exploration of novel therapies including microbiome transplantation, ozone therapy, and phage therapy.

Main Results:

• The skin microbiome plays a critical role in atopic dermatitis (AD) pathogenesis.
• Various therapeutic strategies, from prebiotics to phage therapy, aim to restore a healthy skin microbiome.
• Emerging treatments focus on microbiome modification alongside immunomodulatory therapies.

Conclusions:

• Targeting the skin microbiome is a promising therapeutic avenue for atopic dermatitis (AD).
• A multi-faceted approach, including microbiome modulation, is essential for successful AD treatment.
• Future AD management should integrate microbiome-targeted therapies for improved patient outcomes.
