The simplest classification is ACUTE and CHRONIC inflammation. How do we recognise them?
1. Acute inflammation
Robbins: “Acute inflammation is a rapid host response that serves to deliver leukocytes and plasma proteins, such as antibodies, to sites of infection or tissue injury.”
Examples: Acute appendicitis, abscess
2. Chronic inflammation
Robbins: “Chronic inflammation is inflammation of prolonged duration (weeks or months) in which inflammation, tissue injury and attempts at repair co-exist, in varying combinations.”
Examples: Autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus), tuberculosis infection
