Patients denied symptoms, including vaginal or penile discharge or itching, dysuria, or lower abdominal pain.
Observed by clinician during physical exam.
Elevated WBC is defined as >5 or >4 WBC/hpf for cervical or urethral Gram stain, respectively.
T. vaginaliswas diagnosed by vaginal swab wet mount or culture for women and urethral, urine, or semen culture or urine or semen PCR for men. N. gonorrhoeae and C. trachomatiswere diagnosed by Amplicor CT/NG PCR from first-void urine for men and according to routine clinic protocols for women. Syphilis was diagnosed by positive rapid plasma reagin and confirmed by positive Treponema pallidum hemagglutination assay. HIV was diagnosed by ELISA and confirmed by Western blotting.
