Atopic allergy and immunoglobulins in children with adenoids and recurrent otitis media.

From 274 adenoidectomized children 1-16 years of age two groups were selected: children with a history of recurrent otitis media and/or otosalpingitis (middle ear effusion) and those in which nasal obstruction was the main symptom. In all, 154 children were subjected to an allergy investigation including history, skin tests, eye tests, determination of IgE and RAST, blood eosinophils and immunoglobulins G, A and M. No increased incidence of immunoglobulin deficiency was found in either group in comparison with unselected children. A family history of atopic disease and/or otitis media was highly overrepresented, especially in the children with recurrent otitis media as the reason for the adenoidectomy. Atopic diseases had occurred in 24.4% of the children. Furthermore, in both groups there was a high incidence of positive skin and eye tests. An increased incidence of eosinophila, positive RAST tests and elevated IgE levels were also found. In all, 39.6% of the children had two or more laboratory findings characteristic of the atopic state but no significant difference was found between the two groups. Possible connections between atopic allergy and recurrent otitis media are discussed.
