Added benefit of nucleic acid amplification testing for the diagnosis of Trichomonas vaginalis among men and women attending a sexually transmitted diseases clinic.
Abstract
BACKGROUND: Trichomonas vaginalis (TV) is the most common nonviral sexually transmitted infection (STI) in the world. However, TV is not a reportable STI and, with the exception of HIV-positive women, there are no guidelines for screening in women or men. The objective of this study was to determine the added value of nucleic acid amplification tests (NAATs) for detection of TV in men and women at high risk for infection as well as correlates of infection. METHODS: This was a review of clinical and laboratory data of men and women presenting to the Jefferson County Department of Health Sexually Transmitted Diseases (STD) Clinic and receiving a TV NAAT. RESULTS: During 2012-2013, 6335 patients (3821 women and 2514 men) received a TV NAAT on endocervical, urethral, or urine specimens. Overall TV prevalence was 20.2%; 27.0% in women and 9.8% in men. Correlates of TV among men included age >40 years, African American race, and ≥5 polymorphonuclear cells per high-power field on urethral Gram stain. Age >40 years, African American race, leukorrhea on wet mount, elevated vaginal pH, positive whiff test, and concurrent gonococcal infection were positively associated with TV among women. TV NAAT detected approximately one-third more infections among women than wet mount alone. CONCLUSIONS: TV prevalence among men and women was high in this study, suggesting that both groups should be routinely screened, including those aged >40 years. Improved detection of TV by routine implementation of NAATs should result in better control of this common, treatable STI.

Trichomonas is a relatively common infection among WSW and WSWM, with prevalence rates higher than for chlamydia or gonorrhea, and direct transmission of trichomonas between female partners has been demonstrated.
“Trichomonas is a relatively common infection among WSW and WSWM, with prevalence rates higher than for chlamydia or gonorrhea (306,307), and direct transmission of trichomonas between female partners has been demonstrated (293,294).”
From Sexually Transmitted Infections Treatment Guidelines, 2021 (2021) · cites this paper as [307]
The Results report trichomonas in 27.0% of women attending the STD clinic; Table 3 gives lower counts for chlamydial and gonococcal infection in that clinic population (page not specified). The paper does not identify WSW or WSWM separately, so it does not establish those prevalence comparisons for either group. The sentence cites different sources (293, 294) for direct transmission between female partners, so that clause is not attributed to this paper. (LLM, conf=0.84)

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.
