Abstract
One hundred young patients with recurrent otitis media with effusion (OME) were evaluated for IgE-mediated hypersensitivity by critical analysis of history, physical findings, skin testing for selected antigen, laboratory determination of total IgE, and radioallergosorbent testing (RAST) for six inhalant and two food allergens. The patients could be divided into allergic rhinitis and nonallergic groups. Allergic rhinitis patients had higher total IgE in their serum, and middle ear effusion (MEE). IgE was elevated in 16 of 35 allergic patients. in 8 of these 16 (23% of the allergic group), the IgE/mg protein was higher in the MEE than in the corresponding serum, suggesting local production of IgE. Nasal IgE was substantially increased in the allergic patients; however, in many patients there was no correlation between the corresponding MEE IgE and elevated nasal IgE, suggesting that local production of nasal and middle ear IgE is Independent. We conclude that IgE-mediated allergic reactions may play a role in the pathogenesis of OME in about 23% of young allergic patients.
