Exploring the Associations Between Mediterranean Diet Adherence and Autoinflammation-Associated Skin Diseases.

Area of Science:

• Immunology
• Dermatology
• Nutritional Science

Background:

• Autoinflammatory diseases (AIDs) involve innate immune system dysregulation without infection.
• Some AIDs manifest with skin conditions resembling acne or hidradenitis suppurativa.
• Acne vulgaris, psoriasis, and hidradenitis suppurativa are complex inflammatory dermatoses with innate and adaptive immune involvement.

Purpose of the Study:

• To review evidence on the Mediterranean diet's (MD) association with acne vulgaris, psoriasis, and hidradenitis suppurativa.
• To explore shared and distinct inflammatory pathways in these conditions.
• To identify research gaps and future directions.

Main Methods:

• Literature review of observational studies.
• Analysis of current evidence on MD adherence and inflammatory skin diseases.
• Synthesis of shared and disease-specific inflammatory mechanisms.

Main Results:

• The Mediterranean diet (MD) shows potential for modulating inflammatory mechanisms in skin conditions.
• Evidence primarily comes from observational studies.
• Shared inflammatory pathways exist across acne vulgaris, psoriasis, and hidradenitis suppurativa.

Conclusions:

• The Mediterranean diet (MD) is a potential dietary intervention for inflammatory dermatoses.
• Further interventional studies are crucial to establish clinical efficacy.
• Understanding the interplay between diet and immunity is key for managing these skin conditions.
