Abstract

BACKGROUND: Limited data exist on the risk of Chlamydia trachomatis and Neisseria gonorrhoeae transmission from oropharynx to urethra. We examined urethral C. trachomatis and N. gonorrhoeae positivity among men who have sex with men (MSM) seen at San Francisco City Clinic (San Francisco, CA) during 2007. METHODS: All patients who sought care at the San Francisco City Clinic (the only municipal sexually transmitted disease clinic in San Francisco) received a standardized interview conducted by clinicians. We estimated urethral C. trachomatis and N. gonorrhoeae positivity for 2 groups of visits by MSM who visited during 2007: (1) men who reported their only urethral exposure was receiving fellatio in the previous 3 months and (2) men who reported unprotected insertive anal sex in the previous 3 months. Additionally, urethral C. trachomatis and N. gonorrhoeae positivity was estimated, stratified by human immunodeficiency virus infection status, urogenital symptom history, and whether the patient had been a contact to a sex partner with either chlamydia or gonorrhea. RESULTS: Among MSM who reported only receiving fellatio, urethral C. trachomatis and N. gonorrhoeae positivity were 4.8% and 4.1%, respectively. These positivity estimates were similar to positivity found among MSM who reported unprotected insertive anal sex. CONCLUSIONS: A more complete understanding of the risks of transmission of C. trachomatis and N. gonorrhoeae from oropharynx to urethra will help inform prevention and screening programs.

  • Pharyngeal infections with gonorrhea or chlamydia might be a principal source of urethral infections.

    “Pharyngeal infections with gonorrhea or chlamydia might be a principal source of urethral infections (209–211).”

    From Sexually Transmitted Infections Treatment Guidelines, 2021 (2021) · cites this paper as [211]

    The Discussion (page unavailable) reports urethral chlamydia and gonorrhea among men whose only reported urethral exposure was receiving oral sex, and describes this route as potentially important. It does not establish that pharyngeal infection is a principal source of urethral infection; the study was limited to men who have sex with men attending an STD clinic. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
