Type II |
IgG & IgM mediated damage (blood type incompatibilities) |
|
|
Type III |
Immune complex (basement membrane inflammation) |
|
|
Type IV |
Cell mediated, cytotoxic, delayed hypersensitivity (contact dermatitis, graft rejection) |
|
|
Atophy |
Any chronic local allergy such as hay fever or ashtma |
|
|
Anaphylaxis |
Systemic, sometimes fatal reaction that involves airway obstruction & circulatory collapse |
|
|
IgE-mediated allergies |
Occur when the allergen is passed to the tissue fluids & lymph after contact with a mucus membrane & ends up in a lymph node where B cell recognizes it & clones plasma cells that produce IgE antibodies |
|
|
Hay fever |
Allergic rhinitis Often a seasonal reaction to inhaled pollen or molds & can become chronic |
|
|
Asthma |
Impaired breathing due to severe bronchoconstriction Can be due to inhaled allergens or other stimuli |
|

Atopic dermatitis Sensitization occurs through ingestion, inhalation, & occasionally skin contact |
|
|
Food allergy |
Mode of action is intestinal Food allergies can also affect the skin & respiratory system |

|
Drug allergy |
Drugs are foreign compounds capable of stimulating allergic reactions that range from mild atophy to fatal anaphylaxis. Most often implicated compounds are antibiotics the actual allergen is a happen given off when the liver process the drug |
|
|
Anaphylaxis |
Can be overpowering systemic reaction, characterized by a sudden respiratory & circulatory disruption that can be fatal in minutes. Here the same events are occurring but the concentrations of the chemical mediators & the strength of the response is greatly amplified |
