Integrative Allergy Support: Skin Microbiome, Gut-Skin Axis, and Stress

Learning Objectives

• 1Explain the gut-skin axis and the evidence linking intestinal microbiome dysbiosis to skin barrier dysfunction and atopic dermatitis severity
• 2Analyze the current evidence for specific probiotic strains (Lactobacillus rhamnosus GG, Bifidobacterium animalis AHC7) in preventing and managing canine atopic dermatitis
• 3Apply a skin barrier restoration protocol using topical ceramide/sphingolipid products, appropriate bathing regimens, and essential fatty acid supplementation
• 4Evaluate the role of chronic stress and HPA axis dysregulation in allergic disease flares, and identify behavioral and pharmacologic interventions
• 5Integrate probiotics, prebiotics, skin barrier repair, stress management, and environmental controls into a complete integrative allergy management protocol

Course Syllabus

1. 1
   Meet NalaPreview

   5-year-old female Boxer with atopic dermatitis and seasonal flares despite Cytopoint injections every 4-5 weeks. Requires Apoquel rescue during fall and spring flares. Also has a chronic history of loose stools and intermittent GI upset. Owner asks if there is a connection between gut health and skin disease.

   The Gut-Skin Axis

   Intestinal microbiome composition and diversity. Tight junction proteins maintaining barrier integrity. Leaky gut mechanism and systemic immune activation. Evidence linking microbiome dysbiosis to skin barrier dysfunction. Role of intestinal dysbiosis in atopic dermatitis severity.
