Should urologists care for the pharyngeal infection of Neisseria gonorrhoeae or Chlamydia trachomatis when we treat male urethritis?
Detection of Neisseria gonorrhoeae (NG) or Chlamydia trachomatis (CT) from the pharynx of women or men is not uncommon. However, there is no recommendation how urologists should care for the pharyngeal infection of men with urethritis in Japan. The aim of this study is to clarify the prevalence of NG or CT infection in the pharynx of men and to show a recommendation for urologists. The Japanese reports about the detection of NG or CT from the pharynx or the oral cavity of men in Japan are reviewed in the literature from 1990 to 2011. The prevalence of NG or CT in the pharynx was 4% or 6% in men who attended clinics, and 20% or 6% in men who were positive for NG or CT from genital specimens, respectively. Single 1-g dose ceftriaxone was recommended to treat pharyngeal NG, but no evidence was found for pharyngeal CT. There was not enough evidence for recommendation. However, when men with urethritis only caused by NG or CT are treated through the guideline of the Japanese Society of Sexually Transmitted Infection, we do not think additional tests or treatment for the pharynx are needed when a single 1-g dose ceftriaxone for gonococcal urethritis or a single 1- or 2- g dose azithromycin is prescribed for chlamydial urethritis in Japan.
