Study Notes
Extrinsic Asthma (Atopic Asthma)
- Another name for extrinsic asthma is atopic asthma.
- Extrinsic asthma is most commonly initiated by a type I hypersensitivity reaction.
- It is usually initiated by a reaction to an extrinsic antigen.
- Extrinsic asthma usually starts in childhood.
- Eczema may precede the onset of extrinsic asthma in childhood.
- Extrinsic asthma is associated with a genetic predisposition to develop IgE antibodies.
- Common allergens associated with extrinsic asthma include pollen, dust, fungi, and mites.
- The prognosis for extrinsic asthma is generally good.
- A skin test with the offending antigen is usually positive in individuals with extrinsic asthma.
Intrinsic Asthma
- Intrinsic asthma is initiated by non-immune mechanisms.
- It typically develops later in life.
- Intrinsic asthma is characterized by a lack of atopy in family history.
- The prognosis for intrinsic asthma is generally worse compared to extrinsic asthma.
- Intrinsic asthma is commonly associated with chronic bronchitis.
Comparison of Extrinsic and Intrinsic Asthma
