Objectives

  • Describe the symptoms and treatment for allergic rhinitis, asthma, food allergies, atopic dermatitis, and anaphylaxis.
  • Explain the basic steps in the immune pathway that leads to allergy.
  • Explain the pathophysiology of asthma and apply it to the physical changes that occur in the lungs.
  • Evaluate the treatments for the allergic diseases and what aspect of the immune response they target.
  • Describe some examples of genetic and epigenetic changes that can lead to allergy.
  • Compare and contrast skin testing versus blood testing for allergies, as well as different methods for performing allergy tests.
