Allergic rhinitis due to ragweed pollen

Allergic rhinitis due to ragweed pollen is a seasonal, immunoglobulin E (IgE)–mediated inflammatory disorder of the upper respiratory tract triggered by airborne pollen from the *Ambrosia* species Primarily affecting sensitized children and adults during the late summer and autumn pollination seasons, it involves the nasal mucosa and frequently extends to the conjunctiva

Allergic rhinitis due to ragweed pollen is a seasonal, immunoglobulin E (IgE)–mediated inflammatory disorder of the upper respiratory tract triggered by airborne pollen from the *Ambrosia* species Pathophysiologically, the inhalation of ragweed allergens induces cross-linking of specific IgE on mucosal mast cells and basophils, prompting the release of histamine, leukotrienes, and inflammatory cytokines This acute- and late-phase inflammation classically produces paroxysmal sneezing, nasal conge...
