Extragenital Screening Is Essential for Comprehensive Detection of Chlamydia trachomatis and Neisseria gonorrhoeae in the Pediatric Population [Bacteriology]

Chlamydia trachomatis and Neisseria gonorrhoeae are the two most common causes of sexually transmitted disease in the United States. Studies in adults, mostly in men who have sex with men, have shown that the prevalence of C. trachomatis and N. gonorrhoeae infections is much higher in extragenital sources compared to urogenital sources. A similar large sample of data on the burden of C. trachomatis and N. gonorrhoeae infections by anatomic site is lacking in children. We retrospectively analyzed data from 655 patients tested for C. trachomatis (887 specimens) and N. gonorrhoeae (890 specimens) at the Children’s Hospital of Philadelphia. We restricted the analysis to include patients between 2 and 17 years of age that had all three sources (urine, oropharynx, and rectum) collected at the same visit. The final data set included specimens from all three sources from 148 and 154 patients for C. trachomatis and N. gonorrhoeae, respectively. Specimens were tested for C. trachomatis and N. gonorrhoeae using a Gen-Probe Aptima Combo 2 assay. The burden of C. trachomatis and N. gonorrhoeae infection was significantly higher in the 14- to 17-year age group (24.7%, P = 0.041; 25.8%; P = 0.001) compared to the 10- to 13-year (5.9%; 5.6%), 6- to 9-year (4.6%; 4.6%), and 2- to 5-year (8.3%; 0%) age groups, respectively. The positivity rate for C. trachomatis was highest for rectal (16.2%), followed by urine (5.4%) and oropharyngeal (0.7%) sites. The positivity rate for N. gonorrhoeae...
