Failure of immune system
This section introduces the basic elements of the immune system and immune response. Shown in the slide are the three major mechanisms for immunological failure. There are hypersensitivity reactions in which there is an exaggerated immune response as seen with allergic rhinitis. There is a relative lack of immune response (as in cases of immuno-deficiency) as seen when the body succumbs to infections. Finally, there is the possibility that the immune system reacts to the body’s own tissues (auto-immunity) such as in the case of rheumatoid arthritis.
Examples of an auto-immune disease includes all of the following EXCEPT:
Extra info: Asthma is an example of a hypersensitivity disorder. Rheumatoid arthritis is probably the most widely recognized auto-immune disorder, and Hashimoto’s and lupus demonstrate the spectrum of which auto-immune disorders can be localized.
The following diseases are mediated by IgE antibodies except
