Study Notes
Inflammation Part 2
- Inflammation Part 2 course taught by Neelam Maheshwari, Assoc Prof Pathology, Bond University in 2024
- Course attendance is tracked via Osler
-
Terminologies
- Edema (Odema): Swelling
- Transudate: Fluid-like
- Exudate: Pus-like
- Abscess: Pus in a closed inflamed area
-
Transudate vs. Exudate
- Normal: Hydrostatic pressure = colloid osmotic pressure (fluid balance)
- Transudate: Increased hydrostatic pressure or decreased colloid osmotic pressure; fluid seeps due to pressure difference
- Exudate: Increased interendothelial spaces, loss of cells/proteins, due to inflammation, high protein content
-
Edema Types
- Pitting: indentation remains after slight pressure
- Non-pitting: no indentation
-
Pus
- Exudate rich in pus cells (neutrophils), dead cells, microbes
-
Abscess
- Pus in a closed inflammatory area
-
Morphological Patterns of Acute Inflammation
- Clinical examples discussed
-
Types of Inflammation
- Serous: Thin, pink, watery tissue fluid (low proteins/cells) e.g., Burns, viral blisters, congestive heart failure, peritoneal/pericardial/pleural effusions
- Seropurulent (Exudate): Example given of Appendicitis
- Purulent (Severe): Pyogenic organisms causing central necrosis; walled off by fibrous tissue; antibiotics required e.g., Abscess/Empyema, septic arthritis
- Fibrinous: Severe and longer injury, examples of pericarditis and peritonitis
-
Chronic Inflammation
- Prolonged inflammation (>6 weeks), characterized by mononuclear cell infiltration, tissue destruction, and resolution including angiogenesis and fibrosis
- Causes: Persistent infection (e.g., TB, leprosy, syphilis), exposure to toxins/foreign material (e.g., silicosis, asbestos), autoimmune disorders (e.g., rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease), atherosclerosis, obesity, suture material, or uric acid crystals
-
Example: Mycobacterium tuberculosis
- Slender beaded pink
- Acid-fast bacilli (on ZN stain, not gram stain)
- Cell wall rich in mycolic acid (complex lipids)
- Slow-growing (takes weeks), especially in solid media
- Transmission: airborne
-
Pathogenesis of Tuberculosis (TB)
- Primary Pulmonary TB (0-3 weeks): Mycobacteria enter, macrophages prevent phagolysosome formation, unchecked bacilli replication
- Primary Pulmonary TB (>3 weeks): Alveolar macrophages are activated, CD4+T lymphocytes are recruited and sensitized, forming granulomas;
- Pathology Gross TB lungs: Primary TB (Ghon complex), and secondary TB (re-activated) characterized by caseation and cavities
- Pathology Microscopy Caseating granulomas: Caseous necrosis, epithelioid macrophages, and multinucleate Langhans giant cells are walled-off by fibroblasts
- Non-caseating granulomas: Images provided
- Effects of Inflammation on the body: Include local inflammation (increased permeability, adhesion molecules, and leukocyte activation), systemic protective effects (fever, acute phase proteins), and systemic pathological effects (cardiovascular compromise, multiple tissue involvement)
- Anti-Inflammatory Agents: Degradative enzymes, lipoxins, tyrosine PO4, Aspirin, IL-1 antagonists, corticosteroids (influence prostaglandins, granulocyte distribution, and lysosome stability).
- Summary - Take home message: Inflammation is a complex interplay with a short-term acute phase and a longer-term chronic phase, not always infectious.
- Case Studies (provided): Various case scenarios demonstrating different types and effects of inflammation.
- Key terms: C-reactive protein (CRP), fever, peripheral blood smear, gram stain blood culture, white blood cell count, differentials
