Study Notes
Chronic Inflammation
- The characteristic feature of chronic inflammation is the persistence of inflammation over a prolonged period of time, often lasting from months to years.
Causal Factors of Chronic Inflammation
- Primary chronic inflammation can be caused by microorganisms such as Mycobacterium tuberculosis, Mycobacterium leprae, and certain fungi.
- Persistence of acute inflammation can lead to chronic inflammation, stimulated by factors such as continuous exposure to toxic substances, foreign bodies, or infectious agents.
Immune-Mediated Inflammatory Diseases
- Chronic inflammation is associated with immune-mediated inflammatory diseases such as Rheumatoid Arthritis (RA).
Chronic Inflammation Caused by Toxic Agents
- A characteristic feature of chronic inflammation caused by toxic agents is the formation of granulomas, which are distinct areas of inflammation containing macrophages and other immune cells.
