C.1. Subtopic 1
D. Detailed Pathophysiology
D.1. IgE-mediated hypersensitivity reaction to a foreign antigen, such as a protein, a hapten, or a pollysaccharide.
a. Initial exposure results in the body making specific IgE antibodies to the specific antigen.
a.1. These antibodies attach to receptors of mast cells and basophils
a.1.1. Mast cells and basophils change their cell membranes and release preformed cytokines, chemical mediators, and generation of new potent mediators. These mediators produce the clinical symptoms of anaphylaxis.
a.1.1.1. Subtopic 1
a.1.2. Baophils have a high-affinity receptor for IgE and contain histamine-rich cytoplasmic granules.
a.1.3. Basophils participate in IgE-mediated reactions similar to mast cells.
a.2. Other chemical mediators
These substances can cause contraction of airway smoothmuscle, increased vascular permeability, goblet and mucosal gland secretion, andperipheral vasodilatation.

b.1.2. Histamine is mediated 4 receptor types
1.1. Cardiac effects of H1 include, coronary artery vasospasm and increased rate of depolarization of the SA node.
1.2. H1 Stimulation of nerve endings; stimulation of nerve endings, pruritis, vagal irritant receptors, increased viscosity mucous from gland secretion
2.1. Cardiac effects of H2 stimulation include, increase in rate and force of atrial and ventricular contraction and also decreases the fibrilation threshold.
