The frequency of otitis media with effusion (serous otitis media, secretory otitis media) detected after conventional antibiotic treatment of acute otitis media is approximately 50%. The relationship between pharmacologic compliance and the frequency of otitis media with effusion was studied. A Micrococcus lutea bioinhibition test was used to detect the presence of a substances in the urine that inhibited the growth of this antibiotic-sensitive organism. On the fourth, seventh, and tenth days of antibiotic treatment for acute otitis media urine specimens were collected. Otitis media with effusion was detected in 53% of 66 children who had positive results for M lutea bioinhibition compliance test for all three urine specimens. Electro-acoustic impedance measurements (tympanograms) confirmed the presence of effusion in all children in the effusion group tested by this method. The M lutea bioinhibition assay is a practical, in-office method to validate periodically, during treatment, pharmacologic compliance with antibiotics used for treatment of acute otitis media.
