Occupational allergic rhinitis reaction to psyllium.
We report studies that document a specific rhinitic reaction that developed as a result of occupational exposure to a psyllium-based powdered laxative. This nurse had a nonatopic family history, personal evidence of atopy (skin test reactions to pollen, cat dander, and house dust), and a significant elevation of antipsyllium IgE. Measurements of nasal and lower airway resistance documented only nasal obstruction to brief inhalational challenge to the laxative. Symptomatic relief was achieved with prior treatment with cromolyn. We suggest that nasal airway challenge can document and assess treatment for occupational rhinitis.
