Innovative microbial strategies in atopic dermatitis.

Area of Science:

• Dermatology and immunology, focusing on the skin microbiome's role in inflammatory conditions.

Background:

• Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by severe itching and a significant disease burden.
• Current treatments, primarily corticosteroids, manage inflammation but carry adverse side effects.
• Understanding AD pathogenesis reveals dysbiosis and immune imbalance (Th2 skewing) as key drivers, especially in mild-to-moderate cases.

Purpose of the Study:

• To review emerging microbiome manipulation strategies for atopic dermatitis (AD).
• To highlight the potential of these interventions in modulating the Th1/Th2 immune balance.
• To discuss the application of microbiome-based therapies for AD treatment and prevention.

Main Methods:

• Review of preclinical and clinical studies on various microbiome manipulation approaches.
• Analysis of methods including probiotics, prebiotics, postbiotics, fecal microbiota transplantation, and phage therapy.
• Discussion of herbal fermentation technology involving microorganisms.

Main Results:

• Microbiome manipulation demonstrates potential in improving AD disease states.
• These strategies can regulate the inflammatory system and modulate Th1/Th2 balance.
• Promising results observed across diverse interventions, including those for refractory AD cases.

Conclusions:

• Microbiome-based interventions offer a novel therapeutic strategy for AD with potentially fewer side effects.
• Modulating the gut-skin axis through microbiome manipulation can help control inflammation in AD.
• Further translational research is crucial to optimize the application and efficacy of these therapies for AD treatment and prevention.
