Abstract

Objective Current guidelines for women do not include extragenital screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) and do not mention anal sex behaviour. The objective of this cross-sectional study was to determine the number of potentially missed CT and NG cases by relying on urogenital screening and self-reported anal sex behaviour among women.

Methods Demographic and clinical data of 4658 women attending a community health centre in Los Angeles, California, USA from 2015 to 2018 were examined. CT and NG were detected using nucleic acid amplification test (APTIMA Combo 2, Hologic Gen-Probe, San Diego, California). Demographic and behavioural factors were also examined to assess potentially missed NG/CT cases. Multivariable regression analyses were used to determine whether reported anal sex behaviour predicts NG/CT rectal infection.

Results A total of 193 NG cases and 552 CT cases were identified; however, 53.9% of NG cases and 25.5% of CT cases were identified exclusively through extragenital screening. Of all positive cases of rectal CT, 87.0% did not report anal sex without a condom and 91.3% did not report any anal sex with their last sexual partner. Of all positive cases of rectal NG, 78.9% did not report anal sex without a condom and 76.3% did not report any anal sex with their last sexual partner. Anal sex with last partner was not predictive of NG/CT rectal infection.

Conclusions Relying solely on urogenital screening and reported behaviour misses NG/CT cases. Extragenital NG/CT screening should be conducted in all women regardless of reported anal sex behaviour.
