Study Notes
Allergic Asthma
- Exposure to an allergen in a patient with allergic asthma triggers an immediate allergic reaction, leading to an asthma attack.
- The attack is mediated by antibodies, specifically immunoglobulin E (IgE), which recognize the allergen as a foreign substance (antigen).
- The immune response involves an antigen-antibody reaction on the surface of cells, including:
- Mast cells rich in histamines, leukotrienes, and other inflammatory mediators.
- The released inflammatory mediators trigger:
- Mucosal swelling
- Bronchoconstriction
- These two effects are characteristic of an allergic asthma attack.
