Hypersensitivity is a thingy one may get quized on.
Gell & Goombs classification
| Type (I-IV) | Formal name[1] | Name | Example | Mediator | Pathology |
|---|---|---|---|---|---|
| I | Immediate h. | Allergic h. | anaphylaxis, (atopic) bronchial asthma, allergies | antibodies (IgE) | mast cells, inflammation (esp. eosinophils), edema |
| II | Antibody mediated h. | Cytotoxic antibody dependent h. | Goodpasture syndrome, Graves disease | antibodies (IgG, IgM) | (antibody-mediated) phagocytosis & lysis |
| III | Immune complex mediated h. | Immune complex mediated h. | systemic lupus erythematosus, hypersensitivity pneumonitis,[2] rheumatoid arthritis | antigen-antibody complex | inflammation, vasculitis with fibrinoid necrosis |
| IV | Cell-mediated h. | Delayed-type hypersensitivity | tuberculosis, contact dermatitis, chronic transplant rejection | activated T cells | perivascular inflammation, granulomas |
Memory device ACID:[3]
- Allergic, Cytotoxic-mediated, Immune-complex disease, Delayed hypersensitivity.
