A symbiotic association between humans and microbes has been established over time. Disruptions in gut homeostasis have been linked to immune-mediated inflammatory diseases. Factors such as genetics, environment, diet, age, and medication play a major role in shaping the intestinal microbiome. An altered gut microbiome seems to modulate the progression and severity of inflammatory rheumatic diseases. Disruptions in the eubiotic state of the intestinal microbiome might promote intestinal and extraintestinal autoimmune and inflammatory disorders, although the mechanisms involved are not well understood. In this review, we provide a general overview of several studies concerning intestinal microbiome perturbations and their implications in rheumatoid arthritis, ankylosing spondylitis, and systemic lupus erythematosus. Furthermore, we discuss the relationship between diet, intestinal microbiota, and inflammation.
Atopic dermatitis (AD) is the most common chronic inflammatory skin condition, characterized by multiple recurrent eczematous lesions and intense itchiness. It is a multifactorial skin disorder involving an association between genetic and environmental factors that lead to a defect of the epithelial barrier in conjunction with immunological dysregulation. Over the last decade, there has been an increasing understanding of the role of the human microbiota in preserving skin integrity and that a shift in the homeostasis of these microorganisms may lead to dysbiosis and disease. Diversity in the intestinal microbiome and its role in the etiopathogenesis of AD has been described and has become of great interest. In this report, we have reviewed the importance of the gut microbiome and the possible mechanism in the pathogenesis of AD as well as the therapeutic impact of probiotics and prebiotics.
