Trichomoniasis is one of the most common sexually transmitted infections worldwide. In women, Trichomonas vaginalis infection may present with vaginitis, cervicitis, or pelvic inflammatory disease, while in men it is mainly asymptomatic or causes mild and transient symptoms of urethritis, epididymitis, or prostatitis. In the past, little importance had been given to the impact of T. vaginalis infection on men’s health, since it was believed to be a self-limited condition without sequelae. However, there is growing evidence it is associated with more serious disorders in both men and women and efforts to diagnose and treat this parasitic infection have increased. Recent advances in testing for sexually transmitted diseases using multiplex molecular assays have increased diagnostic opportunities for T. vaginalis infection, especially in men, as detection of the parasite by traditional methods is much more challenging. We describe an unusual case of male urethritis caused by T. vaginalis observed in our consultation of Sexually Transmitted Infections.

Abstract Background Sexually transmitted infections (STIs) are mainly transmitted by sexual contact or similar sexual contact, which can cause diseases of genitourinary organs ,accessory lymphatic system and major organs of the whole body. STIs include clinically symptomatic diseases and asymptomatic infections. The World Health Organization (WHO) reports that More than 1 million sexually transmitted infections (STIs) are acquired every day worldwide.By analyzing the temporal trend of the sexually transmitted infections incidence in China in the past 20 years, we can provide a scientific basis for the further development of prevention and control measures related to sexually transmitted infections. Methods Joinpoint regression model is used to fit the incidence data of three sexually transmitted diseases in China from 1999 to 2018. Annual percentage change (APC) and Average annual percentage Change (AAPC) are calculated to evaluate the temporal trend changes of the incidence of three major sexually transmitted diseases. Results The overall incidence of AIDS/HIV has been on the rise for 20 years, rising by an average of 33.7% per year (P < 0.05). The most obvious increase is in 2002–2005, an average annual increase of 102.5%. The overall incidence of gonorrhea is on a downward trend, decreasing by 4.9% per year on average (P < 0.05).However, its incidence shows a slow rising trend from 2012 to 2018, with an average annual increase of 6.0%. The overall incidence of syphilis is also on the rise, increasing by an average of 9.1% per year (P < 0.05). Except 1999–2003, the incidence of syphilis shows a downward trend, and the other time stages shows a significant upward trend. Conclusions In the past 20 years, the corresponding measures have been taken in China for sexually transmitted infections and achieved remarkable results, but the three major sexually transmitted infections are still in the forefront of the reported notifiable infectious diseases incidence in China. At the same time, all sexually transmitted infections are beginning to shift from high-risk population to the general population, especially adolescents and the floating population.Therefore, China should still pay more attention to the prevention and control of STIs to hold back their further spread or epidemic.

Trichomonas vaginalis (TV) has, in the past, been regarded as a useful marker for other asymptomatic sexually transmitted infections such as gonorrhoea and chlamydia in women. The aim of this study was to determ ine whether TV is still such a m arker. All wom en attending the Department of Genito-urinary Medicine at the Leeds General Infirmary with a diagnosis of TV during 1983 and 1993 were identified and concurrent infections were tabulated. In 1993 approximately 30% of women with TV had at least one other sexually transm itted infection. The prevalence of gonorrhoea in women with trichomoniasis fell from 20% in 1983 to 10% in 1993 whilst the prevalence of chlamydia in these wom en remained unchanged at 15%. Thus trichomoniasis is still frequently associated with other pathogens in women and screening of these women for other infections rem ains essential.

IntroductionConventional care packages around screening for sexually transmitted infections (STIs) entail multiple clinic visits and precipitate losses to follow-up. To prevent these losses, multiplexed technologies for STIs (immunochromatographic tests/devices/assays and molecular assays that can screen multiple pathogens or multiple strains of one STI) can yield same-day results in a single visit. Research evidence of patient-centred (preference, satisfaction) and clinical health outcomes (feasibility, case positivity, uptake, impact) has not been synthesised. We conducted a systematic review to fill this gap.MethodsFor the period 2009–2020, two independent reviewers searched PubMed and Embase, retrieved 4440 citations and abstracted data from 42 relevant studies.ResultsOf 42 studies, 10 (23.8%) evaluated multiplexed immunochromatographic and 32 (76.2%) molecular assays. Outcomes were reported as follows: preference (n=3), satisfaction (n=2), uptake (n=1), feasibility (n=2), case positivity (n=42) and impact (n=11). Screened populations included various at-risk groups. A majority (86.1%–92.4%) of participants preferred (60.2%–97.2%) multiplexed technologies (over conventional testing). Compared with conventional lab-based testing, test uptake improved by 99.4% (hepatitis C), 99.6% (Trichomonas vaginalis), 78.6% (hepatitis B) and 42.0% (HIV). Varying case positivities were documented depending on populations screened: HIV (1.8%–29.3%), hepatitis B (1.1%–23.9%), hepatitis C (0.5%–42.2%), Chlamydia trachomatis (2.8%–30.2%), Neisseria gonorrhoeae (0.0%–30.3%) and T. vaginalis (0.0%–32.7%). Regarding impact, 70.0%–100.0% of screened participants were linked to care, with result turnaround times ranging from 14 min (immunochromatographic assays) to 300 min (molecular assays).ConclusionsCompared with conventional lab-based testing, rapid multiplexed technologies were preferred by testees and led to quicker turnaround times for many STIs yielding same-day results thereby allowing to initiate rapid linkages to care. They were further shown to be highly feasible and impactful for detection and treatment facilitation. Based on these promising results, multiplexed technologies offer potential to screen at-risk populations to reduce onward STI transmission worldwide.

AbstractSexually transmitted infections (STIs) have remained a worldwide public health threat. It is difficult to control the spread of STIs, not only because of heterogeneous sexual transmission between men and women but also because of the complicated effects of sexual transmission among men who have sex with men (MSM) and mother-to-child transmission. Many studies point to the existence of a ‘bisexual bridge’, where STIs spread from the MSM network via bisexual connections. However, it is unclear how the MSM network affects heterosexual networks as well as mother-to-child transmission. To analyse the effect of MSM on the spread of STIs, we divided the population into four subpopulations: (i) women, (ii) men who have sex with women only (MSW), (iii) men who have sex with both men and women (MSMW), (iv) men who have sex with men exclusively (MSME). We calculated the type-reproduction numbers of these four subpopulations, and our analysis determined what preventive measures may be effective. Our analysis shows the impact of bisexual bridge on the spread of STIs does not outweigh their population size. Since MSM and mother-to-child transmission rates do not have a strong synergistic effect when combined, complementary prevention measures are needed. The methodologies and findings we have provided here will contribute greatly to the future development of public health.
