Atopic dermatitis is a chronic inflammatory skin condition characterized by pruritic, eczematous lesions, affecting millions worldwide, particularly children. While the pathogenesis of AD has traditionally been attributed to genetic predisposition and environmental triggers, emerging research has unveiled a significant role of the gut microbiota in modulating immune responses and skin barrier function. Recent studies have illuminated intricate connections between gut dysbiosis, immune dysregulation, and AD pathogenesis, offering novel insights into potential mechanisms driving disease development and progression. Understanding the role of gut microbiota in AD opens new avenues for therapeutic interventions aimed at restoring microbial balance and alleviating disease burden in affected individuals [1].
Beyond its cutaneous manifestations, atopic dermatitis represents a multifaceted disorder with systemic implications, implicating a broader understanding of its aetiology. While genetic predisposition and environmental triggers have long been recognized as key factors in AD pathogenesis, recent attention has turned toward the gut microbiota as a pivotal player in shaping immune responses and skin health. This shift in focus underscores the intricate relationship between the gut microbiome and systemic immune function, with implications extending beyond gastrointestinal health. With the increasing prevalence of AD and its significant impact on patient quality of life, there is a growing urgency to unravel the role of gut microbiota in disease pathogenesis and explore its therapeutic potential in managing this chronic inflammatory condition [2].
The human gut microbiota, comprising trillions of microorganisms, plays a pivotal role in maintaining immune homeostasis and regulating host physiology. Perturbations in gut microbial composition, known as dysbiosis, have been implicated in the pathogenesis of various inflammatory diseases, including AD. In individuals with AD, alterations in gut microbial diversity and composition have been observed, characterized by decreased abundance of beneficial commensal bacteria and enrichment of pathogenic species. These dyspeptic changes can disrupt intestinal barrier integrity, leading to increased intestinal permeability and translocation of microbial products into systemic circulation. Consequently, systemic immune activation and inflammation may exacerbate cutaneous inflammation and compromise skin barrier function, contributing to AD pathogenesis. Furthermore, dysregulated immune responses in AD patients may further perpetuate gut dysbiosis through mechanisms such as altered mucosal immunity and impaired antimicrobial peptide production. Bidirectional communication between the gut and skin, known as the gut-skin axis, underscores the intricate interplay between gut microbiota and cutaneous inflammation in AD. Elucidating the mechanisms underlying gut-skin axis dysfunction in AD holds promise for identifying novel therapeutic targets and developing microbiome-based interventions to modulate disease activity and improve patient outcomes [3].
Recent advancements in high-throughput sequencing and metagenomic analyses have facilitated a deeper understanding of gut microbial composition and its functional implications in health and disease. In the context of AD, studies have revealed distinct microbial signatures associated with disease onset and severity, characterized by alterations in microbial diversity, abundance, and metabolic activity. Symbiosis within the gut microbiota of AD patients is marked by a reduction in beneficial commensal bacteria, such as Bifidobacterium and Faecal bacterium, coupled with an increase in potentially pathogenic species, including Staphylococcus aureus. These microbial imbalances contribute to intestinal barrier dysfunction, leading to increased permeability and systemic dissemination of microbial antigens and inflammatory mediators. Consequently, systemic immune activation and dysregulation may exacerbate cutaneous inflammation and compromise skin barrier function, perpetuating the cycle of AD pathogenesis. Understanding the mechanisms underlying gut symbiosis in AD not only sheds light on disease pathophysiology but also unveils potential targets for therapeutic intervention aimed at restoring microbial balance and modulating immune responses to alleviate disease burden.

Consequently, systemic immune activation and dysregulation may exacerbate cutaneous inflammation and compromise skin barrier function, perpetuating the cycle of AD pathogenesis [4].
Furthermore, emerging evidence suggests that gut microbiota-derived metabolites, such as short-chain fatty acids (SCFAs) and bile acids, play critical roles in modulating immune responses and skin barrier function. SCFAs, produced through fermentation of dietary fibers by gut bacteria, have been shown to exert anti-inflammatory effects by promoting regulatory T cell differentiation and inhibiting pro-inflammatory cytokine production. Conversely, symbiosis-induced alterations in SCFA production may disrupt immune homeostasis and exacerbate inflammatory skin conditions, including AD. Similarly, bile acids, traditionally recognized for their role in lipid digestion and absorption, have recently been implicated in immune regulation and barrier integrity maintenance. Dysregulated bile acid metabolism in AD patients may contribute to intestinal inflammation and barrier dysfunction, thereby exacerbating systemic immune activation and cutaneous inflammation. Understanding the intricate interplay between gut microbial composition, metabolite production, and host immune responses is essential for unraveling the pathophysiology of AD and identifying novel therapeutic targets for intervention. By elucidating these complex mechanisms, researchers aim to develop microbiome-based interventions that restore microbial balance, promote immune tolerance, and alleviate disease burden in AD patients [5].
The burgeoning field of research investigating the role of gut microbiota in AD represents a paradigm shift in our understanding of this complex inflammatory skin disorder. By elucidating the intricate connections between gut dysbiosis, immune dysregulation, and AD pathogenesis, researchers have uncovered novel therapeutic targets and potential interventions for disease management. Strategies aimed at restoring gut microbial balance, such as probiotics, prebiotics, and dietary modifications, hold promise for mitigating disease severity and improving treatment outcomes in AD patients. Moreover, harnessing the gut-skin axis as a therapeutic target may offer innovative approaches for personalized medicine and precision dermatology in AD. Moving forward, continued research efforts aimed at unraveling the mechanisms driving gut-skin axis dysfunction in AD will be crucial for advancing our understanding of disease pathogenesis and developing effective therapeutic strategies to alleviate disease burden and improve the quality of life for individuals living with AD.

Furthermore, strategies targeting the gut-skin axis represent a paradigm shift in dermatological therapeutics, highlighting the interconnectedness of systemic and cutaneous inflammation in AD pathogenesis. Moving forward, collaborative efforts across disciplines will be essential for translating research findings into clinical practice, ultimately improving patient care and enhancing the quality of life for individuals living with AD.
