PATHOPHYSIOLOGY Phase 1 : Sensitization to allergens Phase 1 : Sensitization to allergens In susceptible individuals, exposure to certain foreign proteins leads to allergic sensitization, which is characterized by the production of specific IgE directed against this proteins. Phase 2 : Early and late reactions Phase 2 : Early and late reactions Produced antigen-specific IgE binds to high-affinity IgE receptors on mast cells or basophils, which are present on the nasal mucosa. When the specific protein is inhaled into the nose, it can bind to the IgE on the mast cells, leading to immediate and delayed release of a number of mediators.

CONT’ Sneezing Rhinorrhea Develops in 30 minutes then disappear Due to release of chemical mediators by mast cells such as histamine, prostaglandin and leukotrienes in response to exposure to allergens (type I hypersensitivity). Immediate or early reaction Chronic nasal blockage, congestion approximately 6 hours after exposure to allergens and subsides slowly Due to infiltration of inflammatory cells at site of antigen deposition eosinophil chemotaxis is the main mechanism in the late reaction Delayed or late reaction
