The Itch: Allergies, Asthma, Eczema & Immunology

#102 - Comorbidities of Type 2 Inflammation

Why do conditions like asthma, nasal polyps, or eczema become more severe when they coexist?

Kortney and Dr. Payel Gupta are joined by Dr. Michael Blaiss to explore the common thread linking multiple allergic and inflammatory diseases: Type 2 Inflammation. If you’ve ever wondered why certain conditions often appear together, this deep dive will help you connect the dots.

Type 2 Inflammation is a hot topic in immunology because it’s the engine that drives many allergic and inflammatory diseases. It’s also the key to modern treatment strategies, including targeted biologic therapies. Dr. Blaiss explains how clinicians recognize multiple Type 2-driven conditions in the same patient, why it is important to know the connection between multiple conditions and Type 2 inflammation, and the big-picture benefits of treating inflammation aggressively to prevent complications.

What We Cover in our Episode about The Diseases Related to Type 2 Inflammation

• Conditions Related to Type 2 Inflammation: Explore how chronic rhinosinusitis with nasal polyps (CRSwNP), rhinitis, asthma, atopic dermatitis (eczema), prurigo nodularis, eosinophilic esophagitis (EoE), and food allergies can all share a common inflammatory pathway.
• The Likelihood of Having Multiple Type 2 Conditions: How often do patients have more than one condition related to Type 2 Inflammation, and why is recognizing overlap a potential game-changer for diagnosis and treatment?
• Treating the Root Inflammation vs. Individual Symptoms: Discover how clinicians decide whether to address each condition separately or tackle the underlying Type 2 inflammatory process affecting them all.
• Markers & Personalized Medicine: Dr. Blaiss discusses whether potential tests, such as eosinophil counts or IgE levels, can confirm Type 2 inflammation. He also explains how knowing you have Type 2 Inflammation can help guide targeted therapy.
• Prevention & Aggressive Intervention: Understand why it’s crucial to treat inflammation early to reduce the risk of developing multiple Type 2 conditions and how this proactive approach benefits long-term health.
