Abstract
OBJECTIVE Male genital infections are a major problem due to their high frequency and morbidity and their role in cases of male infertility. We studied the presence, in males assisted in specialized care, of non-ulcerative genital tract infections-producing agents. METHODS We studied descriptively and retrospective microbiological results of 3,066 samples of male patients, with diagnosis of genital tract infection episode, received between January 1, 2016 and December 31, 2017. Detection of microorganisms in the sample was performed using techniques of artificial culture and PCR (BD-MAX). RESULTS Positive results were obtained in 451 samples (14.71%). By culture, the most frequent pathogens were Enterobacterales (18.40%), Enterococcus (13.75%), Haemophilus (8.65%), Neisseria gonorrhoeae (8.43%), Ureaplasma (5.10%), and Candida (3.77%). By polymerase chain reaction (PCR), the most frequent were N. gonorrhoeae (28.37%), Chlamydia trachomatis (26.95%), Ureaplasma urealyticum (17.73%), Mycoplasma hominis/Ureaplasma parvum (10.64%), and Mycoplasma genitalium (7.10%). The age was older in patients infected with Enterobacterales, Candida, or Enterococcus and younger in those infected with N. gonorrhoeae. CONCLUSIONS N. gonorrhoeae and C. trachomatis are still more common in male genital infection pathogens, although other culturable microorganisms have an important role. These findings demonstrate the importance of systematically applying both conventional culture and PCR techniques for pathogen detection.

Abstract
BackgroundSexually transmitted infection (STI) diagnoses are increasing and efforts to reduce transmission have failed. There are major uncertainties in the evidence base surrounding the delivery of STI care for men.AimTo improve the sexual health of young men in the UK by determining optimal strategies for STI testing and careObjectivesTo develop an evidence-based clinical algorithm for STI testing in asymptomatic men; model mathematically the epidemiological and economic impact of removing microscopy from routine STI testing in asymptomatic men; conduct a pilot randomised controlled trial (RCT) of accelerated partner therapy (APT; new models of partner notification to rapidly treat male sex partners of people with STIs) in primary care; explore the acceptability of diverse venues for STI screening in men; and determine optimal models for the delivery of screening.DesignSystematic review of the clinical consequences of asymptomatic non-chlamydial, non-gonococcal urethritis (NCNGU); case–control study of factors associated with NCNGU; mathematical modelling of the epidemiological and economic impact of removing microscopy from asymptomatic screening and cost-effectiveness analysis; pilot RCT of APT for male sex partners of women diagnosed withChlamydia trachomatisinfection in primary care; stratified random probability sample survey of UK young men; qualitative study of men’s views on accessing STI testing; SPORTSMART pilot cluster RCT of two STI screening interventions in amateur football clubs; and anonymous questionnaire survey of STI risk and previous testing behaviour in men in football clubs.SettingsGeneral population, genitourinary medicine clinic attenders, general practice and community contraception and sexual health clinic attenders and amateur football clubs.ParticipantsMen and women.InterventionsPartner notification interventions: APTHotline [telephone assessment of partner(s)] and APTPharmacy [community pharmacist assessment of partner(s)]. SPORTSMART interventions: football captain-led and health adviser-led promotion of urine-based STI screening.Main outcome measuresFor the APT pilot RCT, the primary outcome, determined for each contactable partner, was whether or not they were considered to have been treated within 6 weeks of index diagnosis. For the SPORTSMART pilot RCT, the primary outcome was the proportion of eligible men accepting screening.ResultsNon-chlamydial, non-gonococcal urethritis is not associated with significant clinical consequences for men or their sexual partners but study quality is poor (systematic review). Men with symptomatic and asymptomatic NCNGU and healthy men share similar demographic, behavioural and clinical variables (case–control study). Removal of urethral microscopy from routine asymptomatic screening is likely to lead to a small rise in pelvic inflammatory disease (PID) but could save > £5M over 20 years (mathematical modelling and health economics analysis). In the APT pilot RCT the proportion of partners treated by the APTHotline [39/111 (35%)], APTPharmacy [46/100 (46%)] and standard patient referral [46/102 (45%)] did not meet national standards but exceeded previously reported outcomes in community settings. Men’s reported willingness to access self-sampling kits for STIs and human immunodeficiency virus infection was high. Traditional health-care settings were preferred but sports venues were acceptable to half of men who played sport (random probability sample survey). Men appear to prefer a ‘straightforward’ approach to STI screening, accessible as part of their daily activities (qualitative study). Uptake of STI screening in the SPORTSMART RCT was high, irrespective of arm [captain led 28/56 (50%); health-care professional led 31/46 (67%); poster only 31/51 (61%)], and costs were similar. Men were at risk of STIs but previous testing was common.ConclusionsMen find traditional health-care settings the most acceptable places to access STI screening. Self-sampling kits in football clubs could widen access to screening and offer a public health impact for men with limited local sexual health services. Available evidence does not support an association between asymptomatic NCNGU and significant adverse clinical outcomes for men or their sexual partners but the literature is of poor quality. Similarities in characteristics of men with and without NCNGU precluded development of a meaningful clinical algorithm to guide STI testing in asymptomatic men. The mathematical modelling and cost-effectiveness analysis of removing all asymptomatic urethral microscopy screening suggests that this would result in a small rise in adverse outcomes such as PID but that it would be highly cost-effective. APT appears to improve outcomes of partner notification in community settings but outcomes still fail to meet national standards. Priorities for future work include improving understanding of men’s collective behaviours and how these can be harnessed to improve health outcomes; exploring barriers to and facilitators of opportunistic STI screening for men attending general practice, with development of evidence-based interventions to increase the offer and uptake of screening; further development of APT for community settings; and studies to improve knowledge of factors specific to screening men who have sex with men (MSM) and, in particular, how, with the different epidemiology of STIs in MSM and the current narrow focus on chlamydia, this could negatively impact MSM’s sexual health.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Abstract
We present the updated International Union against Sexually Transmitted Infections (IUSTI) guideline for the management of non-gonococcal urethritis in men. This guideline recommends confirmation of urethritis in symptomatic men before starting treatment. It does not recommend testing asymptomatic men for the presence of urethritis. All men with urethritis should be tested for Chlamydia trachomatis and Neisseria gonorrhoeae and ideally Mycoplasma genitalium using a nucleic acid amplification test (NAAT) as this is highly likely to improve clinical outcomes. If a NAAT is positive for gonorrhoea, a culture should be performed before treatment. In view of the increasing evidence that azithromycin 1 g may result in the development of antimicrobial resistance in M. genitalium, azithromycin 1 g is no longer recommended as first line therapy, which should be doxycycline 100 mg bd for seven days. If azithromycin is to be prescribed an extended course of 500 mg stat, then 250 mg daily for four days is to be preferred over 1 g stat. In men with persistent NGU, M. genitalium NAAT testing is recommended if not previously undertaken, as is Trichomonas vaginalis NAAT testing in populations where T. vaginalis is detectable in >2% of symptomatic women.

Abstract
OBJECTIVES To measure the effect of changing the point-of-care (POC) testing algorithm of urogenital chlamydia for all male high-risk patients to those with only symptoms with respect to: diagnostic accuracy, loss to follow-up, correctly managed consultations and costs. METHODS Retrospective comparison of the diagnostic accuracy and cost-effectiveness of Gram-stained urethral smear analysis for the POC management of urogenital Chlamydia trachomatis infections. Between 2008 and 2009 Gram-stained urethral smear analysis was offered to all men irrespective of symptoms; between 2010 and 2011 only to those with symptoms. The Aptima CT assay was the reference diagnostic test. RESULTS The number of examined Gram-stained smears in the two periods was respectively 7185 (2008-2009 period) and 18,852 (2010-2011 period). The sensitivity of the Gram stain analysis was respectively 83.8% (95% CI 81.2% to 86.1%) and 91.0% (95% CI 89.5% to 92.3%) (p<0.001). The specificity was respectively 74.1% (95% CI 73.0% to 75.2%) and 53.1% (95% CI 51.8% to 54.4%) (p<0.001). The positive predictive value was low in both periods, respectively 31.7% (95% CI 29.8% to 33.6%) and 35.6% (95% CI 34.1% to 37.1%) (p=0.002), whereas the negative predictive value was high, respectively 97.0% (95% CI 96.4% to 97.4%) and 95.4% (95% CI 94.6% to 96.1%) (p=0.002). The loss to follow-up rate between 2008-2009 and 2010-2011 was, respectively, 1.8% (95% CI 1.0% to 2.9%) vs 2.3% (95% CI 1.7% to 3.0%) (p=0.36). There was a small difference in overtreatment, 68.0% (95% CI 66.0% to 69.8%) vs 64.1% (95% CI 62.6% to 65.5%) (p=0.001). The cost per correctly managed consultation was 14.3% lower in the 2010-2011 period (€94.31 vs €80.82). The percentage of delayed treated infections was significantly lower in the 2008-2009 period (10.5%) compared with the 2010-2011 period (22.8%) (p<0.001). CONCLUSIONS With a high sensitivity in male high-risk patients, the Gram-stained urethral smear is a useful POC test to detect urogenital C. trachomatis. When offered only to men with urogenital symptoms the specificity decreases but the cost per correctly managed consultation is reduced with 14.3% without a significant difference in loss to follow-up but with a significantly higher rate of delayed treatment.

Abstract
Opinions are divided on whether to screen asymptomatic men for non-chlamydial non-gonococcal urethritis (NCNGU). We systematically reviewed the literature to determine whether male asymptomatic NCNGU is associated with significant clinical outcomes for men and/or their sexual partners. We searched electronic databases and reference lists from retrieved articles and reviews. No studies reporting clinical outcomes in men with asymptomatic NCNGU were identified. Two eligible studies report rates of sexually transmitted infections (STIs) in female partners of men with asymptomatic NCNGU; Chlamydia trachomatis was detected in 2.4% and 8.3% of these women. The evidence available is insufficient in quality and breadth to enable us to conclude whether asymptomatic NCNGU is associated with significant health consequences for men or their sexual partners; however, clinical consequences of asymptomatic NCNGU are poorly investigated. Clinicians should be aware of the limitations of the evidence on which current screening guidelines for asymptomatic men are based.

Abstract
We collected data from 218 HIV-infected men to assess the usefulness of the urethral smear and symptoms in predicting Chlamydia trachomatis infection. Prevalence of urethral chlamydia was 9%. A polymorphonuclear leucocyte (PMNL) count ≥5 was 73% sensitive and 71% specific for C. trachomatis infection. Adjusted odds ratio for risk of chlamydial infection was significant for urethral irritation (7.48; 1.54–36.4), a PMNL count of 20 or more (9.83; 2.52–8.4) and a PMNL count of 5–19 (4.10; 1.34–12.5). We had to perform 50 urethral smears in HIV-positive men without symptoms to treat one case of C. trachomatis at the time of visit. Findings suggest that the presence of symptoms, in particular urethral irritation may be associated with chlamydial urethritis and that the higher the urethral PMNL count, the more likely it is for C. trachomatis to be detected. The findings in this study also lend further support to recent guidelines that urethral microscopy is not useful in asymptomatic men and hence should be abandoned.
