[Immunologic studies of secretory otitis].

Evaluation of total serum proteins and RIST immunoelectrophoresis of immunoglobulins IgG, IgA and IgM were carried out on a group of 35 children of both sexes suffering from secretory otitis. The transudate aspirated from the middle ear was examined only by immunoelectrophoresis. The values for albumin and gammaglobulins were decreased for all the patients. The values for RIST were significantly lower than those where an allergic cause was present. The values for immunoglobulins in transudate were also significantly lower than normal.
