IMMUNOGLOBULINS IN SERUM AND NASAL SECRETION. A COMPARISON BETWEEN PATIENTS WITH ASPIRIN HYPERSENSITIVITY AND ALLERGIC RHINITIS.

Immunoglobulins A, E and G were studied in serum and nasal secretion from patients with allergic rhinitis, chronic rhinitis and aspirin hypersensitivity, and normal controls. The allergic patients differed from the other groups in having higher IgE values, both in serum and in nasal secretion. The patients with aspirin hypersensitivity did not differ from the control group regarding the IgE values. No difference between the groups was found with respect to IgA and IgG. The results indicate that reaginic antibodies are not involved in causing aspirin hypersensitivity. [ABSTRACT FROM AUTHOR]
