[Chlamydia pneumoniae in otorhinolaryngological infection].

I detail clinical observation, examination, and treatment of regional otorhinolaryngological infection 3-cases of acute sinusitis and 1 of acute pharyngitis-due to Chlamydia pneumoniae, occurring between January 2002 and December 2004. Special clinical features by infection with C. pneumoniae were not recognized in the 4 cases, while ordinary clinical features by conventional bacterial infection were recognized, such as pharyngalgia and pyrexia for acute pharyngitis and purulent discharge and headache for acute sinusitis. I diagnosed an infection for C. pneumoniae for 1 case with acute sinusitis by detecting a causative factor gene of C. pneumoniae by PCR. I diagnosed C. pneumoniae for the 2 other cases of acute sinusitis and the case of acute pharyngitis by confirming antibody titer of C. pneumoniae ascending by serological verification. The 1 adult acute sinusitis case and the acute pharyngitis case were treated using a new quinolone antimicrobial agent. I administered macrolides antimicrobial agent to the 2 acute pediatric sinusitis cases and attained good outcomes without recurrence. We wish to emphasize that C. pneumoniae infectionin in the otorhinolaryngological setting has not been adequately reported and has not received the attention it deserved. If a good outcome cannot be attained using the beta-lactam antimicrobial agent for otorhinolaryngological infection, it should be sought using a macrolides antimicrobial agent or the new quinolone antimicrobial agent for adults and with the macrolides antimicrobial agent for pediatric cases.
