Area of Science:

• Immunology and Pharmacology
• Rheumatology, Dermatology, and Gastroenterology

Background:

• Immune-mediated inflammatory diseases (IMIDs) represent a spectrum from autoinflammatory to autoimmune conditions.
• These diseases involve distinct components of the innate and adaptive immune systems.
• Understanding these distinctions is crucial for effective therapeutic strategies.

Purpose of the Study:

• To present a simplified model for understanding the mechanisms of disease-modifying anti-inflammatory drugs (DMAIDs).
• To correlate DMAID action with specific immune system involvement in various IMIDs.
• To provide a framework for the application of DMAIDs in rheumatology, dermatology, and gastroenterology.

Main Methods:

• Categorization of IMIDs along an autoinflammatory-autoimmune spectrum based on immune system involvement.
• Classification of DMAIDs based on their targeted immune components.
• Review of existing literature on DMAID efficacy in distinct IMIDs.

Main Results:

• IMIDs can be effectively modeled on a spectrum defined by innate versus adaptive immune system dominance.
• Specific classes of DMAIDs, including TNF blockers, IL-1 blockers, IL-6 receptor blockers, IL-17 blockers, IL-23 blockers, and janus kinase inhibitors, target distinct immune pathways.
• DMAIDs demonstrate efficacy in specific IMIDs aligned with their targeted immune mechanisms.

Conclusions:

• The proposed model simplifies the understanding of DMAID action in IMIDs.
• Targeting specific immune pathways with appropriate DMAIDs is key to successful treatment across rheumatology, dermatology, and gastroenterology.
• This framework aids in optimizing therapeutic selection for patients with IMIDs.
