Pilot Study to Evaluate the Appropriate Management of Patients With Coexistent Bacterial Vaginosis and Cervicitis

A pilot study was performed to obtain preliminary data regarding the need for targeted therapy of bacterial vaginosis (BV) when it accompanies clinically defined cervicitis. Specifically, women attending a sexually transmitted disease (STD) clinic with clinically defined BV and cervicitis were treated in the first phase of the study with doxycycline alone. In phase II, the patients received doxycycline and concomitant intravaginal metronidazole gel. All patients were reexamined 3–4 weeks after therapy. Persistence of BV occurred in 18/19 (95%) of women in phase I vs. 1/7 (14%) of women in phase II (P < 0.001). We concluded that, in women with coexistent clinically defined cervicitis and BV, the treatment of cervicitis does not result in a normalization of the vaginal flora

Meatal Swabs Contain Less Cellular Material and Are Associated with a Decrease in Gram Stain Smear Quality Compared to Urethral Swabs in Men

Urethral swabs are the samples of choice for point-of-care Gram stain testing to diagnose Neisseria gonorrhoeae infection and nongonococcal urethritis (NGU) in men. As an alternative to urethral swabs, meatal swabs have been recommended for the collection of urethral discharge to diagnose N. gonorrhoeae and Chlamydia trachomatis infection in certain populations by nucleic acid amplification testing (NAAT), as they involve a less invasive collection method. However, as meatal swabs could be sampling a reduced surface area and result in fewer collected epithelial cells compared to urethral swabs, the adequacy of meatal swab specimens to collect sufficient cellular material for Gram stain testing remains unknown. We enrolled 66 men who underwent either urethral or meatal swabbing and compared the cellular content and Gram stain failure rate. We measured the difference in swab cellular content using the Cepheid Xpert CT/NG sample adequacy control crossing threshold (SACCT) and determined the failure rate of Gram stain smears (GSS) due to insufficient cellular material. In the absence of discharge, meatal smears were associated with a significant reduction in cellular content (P = 0.0118), which corresponded with a GSS failure rate significantly higher than that for urethral swabs (45% versus 3%, respectively; P < 0.0001). When discharge was present, there was no difference among results from urethral and meatal swabs. Therefore, if GSS testing is being considered for point-of-care diagnosis of N. gonorrhoeae infection or NGU in men, meatal swabs should be avoided in the absence of a visible discharge

Delay in Seeking Healthcare Services Following Onset of Urethritis Symptoms in Men

Background: Symptom awareness, behavioral factors, and other barriers associated with timely sexually transmitted infection (STI) health care provision in men is not well studied. Methods: Men attending an STI clinic answered a questionnaire regarding their symptoms, sexual behavior, and sociodemographic and behavioral characteristics. Characteristics of symptomatic men were compared between those who did and did not delay seeking health care services. Delayed care seeking was defined as clinic attendance longer than 7 days after symptoms, whereas early care seeking was defined as clinic attendance of 7 days or less. Results: Over a quarter (n = 43 [27.7%]) of men with urethritis symptoms (urethral discharge or dysuria) delayed seeking care for more than 7 days. Compared with men who sought treatment within 7 days, those that delayed care worried for longer periods that their symptoms were STI-related, were more likely to attempt self-treatment of STI symptoms, were more likely to continue engaging in sexual activity, and were less likely to use a condom during their last sexual encounter. Conversely, men that delayed care seeking were less likely to have urethral discharge on physical examination, to have 5 or more polymorphonuclear leukocytes, and to test positive for Neisseria gonorrhoeae. When compared with men that sought care earlier, men that delayed care seeking had fewer overall and new partners in the past 30 days. Conclusions: Our data suggest that over a quarter of men aware of STI symptoms delay seeking health services. Interventions that promote better patient understanding of the importance of symptom recognition and that facilitate timely access to care may provide new opportunities to reduce STI transmission

Defining the Urethritis Syndrome in Men Using Patient Reported Symptoms

To evaluate self-reported symptoms to guide urethritis diagnosis, symptomatic men being evaluated for urethritis were asked about seven symptoms captured during history-taking. Discharge and dysuria were significantly associated with urethritis and, when combined with genital irritation and itching, identified 95% of urethritis cases; odor and urinary frequency performed poorly

Rapid Diagnosis of Trichomonas vaginalis by Testing Vaginal Swabs in an Isothermal Helicase-Dependent AmpliVue Assay

The AmpliVue™ Trichomonas Assay (Quidel) is a new FDA cleared rapid test for qualitative detection of Trichomonas vaginalis (TV) DNA in female vaginal specimens. The assay is based on BioHelix’s Helicase-Dependent Amplification (HDA) isothermal technology in conjunction with a disposable lateral-flow detection device, with a total turn-around time of approximately 45 minutes

Home Screening for Bacterial Vaginosis to Prevent Sexually Transmitted Diseases

Background. Longitudinal studies have consistently found a significant association between bacterial vaginosis (BV) and acquisition of sexually transmitted diseases. However, there are limited prospective data to confirm these findings

Sexually transmitted infections: challenges ahead.

WHO estimated that nearly 1 million people become infected every day with any of four curable sexually transmitted infections (STIs): chlamydia, gonorrhoea, syphilis, and trichomoniasis. Despite their high global incidence, STIs remain a neglected area of research. In this Commission, we have prioritised five areas that represent particular challenges in STI treatment and control. Chlamydia remains the most commonly diagnosed bacterial STI in high-income countries despite widespread testing recommendations, sensitive and specific non-invasive testing techniques, and cheap effective therapy. We discuss the challenges for chlamydia control and evidence to support a shift from the current focus on infection-based screening to improved management of diagnosed cases and of chlamydial morbidity, such as pelvic inflammatory disease. The emergence and spread of antimicrobial resistance in Neisseria gonorrhoeae is globally recognised. We review current and potential future control and treatment strategies, with a focus on novel antimicrobials. Bacterial vaginosis is the most common vaginal disorder in women, but current treatments are associated with frequent recurrence. Recurrence after treatment might relate to evidence that suggests sexual transmission is integral to the pathogenesis of bacterial vaginosis, which has substantial implications for the development of effective management approaches. STIs disproportionately affect low-income and middle-income countries. We review strategies for case management, focusing on point-of-care tests that hold considerable potential for improving STI control. Lastly, STIs in men who have sex with men have increased since the late 1990s. We discuss the contribution of new biomedical HIV prevention strategies and risk compensation. Overall, this Commission aims to enhance the understanding of some of the key challenges facing the field of STIs, and outlines new approaches to improve the clinical management of STIs and public health

The Association Between Oral Contraceptives, Depot-Medroxyprogesterone Acetate, and Trichomoniasis

Hormonal contraception use by women may increase the risk of acquiring certain sexually transmitted infections. We explored the effect of hormonal contraceptive use, specifically oral contraception (OC), and depot-medroxyprogesterone acetate (DMPA) on Trichomonas vaginalis infections in women

Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis Infections in Men With Nongonococcal Urethritis: Predictors and Persistence After Therapy

Background. Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), and Trichomonas vaginalis (TV) are sexually transmitted infections (STIs) associated with nongonococcal urethritis (NGU). We assessed their predictors and persistence after treatment
