This literature review explores the complex interplay between atopic dermatitis (AD) and the microbiota, highlighting the role of the gut microbiome in AD pathogenesis and treatment. AD is a chronic inflammatory skin condition with a high prevalence, influenced by genetic and environmental factors, including immune system dysregulation and impaired skin barrier. The review emphasizes the importance of the gut microbiota in modulating skin conditions, particularly in AD. Dysbiosis of the gut microbiota, characterized by an imbalance of bacterial species, is a significant factor contributing to the development and exacerbation of AD. Probiotics, dietary adjustments, hygiene, and living conditions are discussed as potential strategies for modulating AD. The review also highlights the role of short-chain fatty acids (SCFAs) produced by gut bacteria in regulating immune responses and skin barrier function. Additionally, the review examines the bidirectional relationship between gastrointestinal and skin disorders, suggesting that modulating the gut microbiota can improve skin conditions, especially in AD patients. While probiotics show promise in managing AD symptoms, further research is needed to establish their efficacy and optimal usage. Factors such as hygiene, breastfeeding, residency conditions, antibiotic intake, dietary changes, and formula use are also discussed as influences on the development of AD and the microbiota. The review concludes by emphasizing the need for further research to understand the mechanisms of these interactions and to develop new therapies for AD.This literature review explores the complex interplay between atopic dermatitis (AD) and the microbiota, highlighting the role of the gut microbiome in AD pathogenesis and treatment.
