[Measuring of immune complexes and antinuclear antibodies in effusion of secretory otitis media].
Immune complexes (IC) and antinuclear antibodies (ANA) in middle ear effusions from 40 cases (45 ears) of secretory otitis media were measured using PEG precipitation method and fluorescent microscopy. The range of absorbence for IC varies between 0.124-0.512 in patients and is higher than those (0.132) in normal human sera. Thirty-two ears (71.1%) are ANA positive. The result indicates that secretory otitis media is related with autoimmunity. The deposit of IC may be one of the causes of effusion in otitis media.
