Purpose: To study the sexual behavior and status of sexually transmitted urethritis (STU) in the elderly population of South Korea., Materials and Methods: Congregating places for elderly population, which were selected on the expected risk of sexually transmitted infections, were visited to study their sexual behavior, awareness on sexually transmitted diseases (STDs), and STU status using a specially developed survey and urine polymerase chain reaction (PCR) test. In addition, analysis of the Health Insurance Review & Assessment Service (HIRA) database was done to study the nationwide status and trends of STU of the elderly population., Results: The study found that approximately 42% of elderly South Koreans were sexually active. Elderlies in the high-risk group showed a higher percentage of multiple sexual partners and prostitution than elderlies in the low-risk group. Only 3% and 14% in the low-risk group and high-risk group used condoms, showing a very low rate of condom use. Both the urine PCR results and HIRA database analysis showed that the prevalence of STU was not high and it remained stable in recent years, implying that currently, STU is not a significant burden on public health in the elderly population of South Korea., Conclusions: The current study presented the sexual behavior in the elderly population of South Korea, as well as the recent prevalence and trend of STU in the elderly population. These results may be used as baseline data for future study, education, prevention and public campaign plan for STDs in the elderly population., Competing Interests: CONFLICTS OF INTEREST: The authors have nothing to disclose.

Objective: Although Chlamydia trachomatis (CT) and Mycoplasma genitalium (MG) are major causes of non-gonococcal urethritis (NGU), up to 50% of cases are of unknown aetiology. We sought to identify urethral exposures at last sexual episode associated with NGU and non-CT/non-MG NGU to identify anatomical sites from which aetiologically relevant micro-organisms may be acquired., Methods: We enrolled STD clinic patients with and without NGU assigned male sex at birth and age ≥16 into a cross-sectional study. NGU was urethral symptoms or visible discharge plus ≥5 polymorphonuclear leucocytes without Neisseria gonorrhoeae . Urine was tested for CT and MG (Aptima). We used logistic regression to estimate the association between urethral exposures at last sex and NGU separately among cisgender men and transgender women who have sex with men (MSM/TGWSM) and cisgender men who have sex with women (MSW)., Results: Between 8 August 2014 and 1 November 2017, we enrolled 432 patients, including 183 MSM/TGWSM (118 NGU+, 65 NGU-) and 249 MSW (126 NGU+, 123 NGU-). The mean age was 34; 59% were white. CT and MG were detected in 72 (30%) and 49 (20%) NGU+ participants, respectively. Compared with MSM/TGWSM reporting only non-urethral exposures at last sex, those reporting insertive anal intercourse (IAI) only (adjusted OR (AOR)=4.46, 95% CI 1.09 to 18.19) and IAI with insertive oral sex (IOS) (AOR=7.88, 95% CI 2.67 to 23.26) had higher odds of NGU. MSM/TGWSM reporting IOS only had no significant increased odds (AOR=1.67, 95% CI 0.58 to 4.85). Compared with MSW whose only urethral exposure at last sex was vaginal sex (VS), MSW reporting IOS and VS had similar odds of NGU (OR=0.84, 95% CI 0.50 to 1.41). The results were similar for non-CT/non-MG NGU., Conclusions: Among MSM/TGWSM, IAI may lead to transmission of yet-unidentified rectal micro-organisms that cause non-CT/non-MG NGU, in addition to transmission of known pathogens. Sites of urethral exposure appear less important for understanding NGU risk among MSW due to minimal variation in behaviour., Competing Interests: Competing interests: CMK and LEM have received donations of test kits and reagents from Hologic.

Purpose: Evaluate the main etiologies and clinical characteristics of male urethral stricture disease (USD) in Brazil., Methods: This multicentric study was performed using retrospective data collected from six Brazilian referral centers of urethral reconstruction. The database comprised data from 899 patients with USD who had undergone surgical treatment from 2008 to 2018. Age, stricture site and primary stricture etiology were identified for each patient., Results: The mean age was 52.13 ± 16.9 years. The most common etiology was iatrogenic (43.4%), followed by idiopathic (21.7%), trauma (21.5%) and inflammatory (13.7%). Of the iatrogenic causes, 59% were secondary to urethral instrumentation (60% by urethral catheterization and 40% by transurethral procedures), 24.8% by other procedures (prostatectomy, radiotherapy, postectomy) and 16.2% by failed hypospadia repairs. Pelvic fracture urethral distraction injuries were responsible for most of the trauma-related strictures (62.7%). When stratified by age, the most common stricture etiology was trauma in the 0-39 years old group (42.8%), idiopathic in the 40-59 years old group (32.4%) and iatrogenic in patients over 60 years old (68%). In regard to the stricture site, 80% presented with an anterior urethral stricture and 20% with a posterior stenosis. In the anterior stenosis group, the most common stricture site was bulbar (39.5%)., Conclusion: In Brazil, as in many developed countries, the most common cause of urethral stricture diseases is iatrogenic, especially urethral catheterization. These findings emphasize the need of a careful urethral manipulation and a better training of healthcare professionals. Trauma is still responsible for a great proportion of strictures and inflammatory etiologies are now less frequently observed.

Context: Urethritis prevalence in Europe changed in the last years due to both the increase of migratory streams from North Africa and the more frequent exposition of males to relevant risk factors. Owing to these reasons, urethritis treatment should be optimized by accurate microbiological investigations to avoid the risk of persistence, recurrence, or reinfection., Objective: The aim of this systematic review is to optimize the treatments for urethritis and investigate the applicability of nucleic acid amplification test (NAAT) as the primary microbiological investigation., Evidence Acquisition: A literature search in Medline, Cochrane, and Google Scholar databases was conducted up to June 2018. Subject headings were selected as follows: Urethritis OR gonococcal urethritis OR non-gonococcal urethritis AND Antibiotics OR Recurrence. A total of 528 abstracts were identified and selected. Finally, 12 full-text articles were selected for a qualitative synthesis. The Preferred Reported Items for Systematic Reviews and Meta-Analyses statement was used to perform an accurate research checklist and report., Evidence Synthesis: Empirical treatments are no more recommended, although a broad spectrum of antibiotic therapy may be initiated while awaiting the results from pathogens' microbiological characterization. First-line treatment for gonococcal urethritis consists of a single dose of ceftriaxone/azithromycin combined therapy. Specific therapies should be initiated for nongonococcal urethritis according to each single pathogen involved in the infection process. Owing to this reason, NAAT is mandatory in the clinical approach to the disease, although the Gram stain of urethral discharge or smear remains applicable for some less frequent nongonococcal urethritis. Moreover, the urethritis "modern view" also includes noninfectious etiologies that occurred after traumas or injection of irritating compounds. Sexual abstinence of at least 7 d should be observed from the start of treatment to avoid reinfection, while sexual partners should evenly be treated., Conclusions: The treatment of urethritis implies accurate determination of pathogens involved in the infection process by NAAT with subsequent appropriate antibiotic therapy, thus avoiding the risk of antibiotic resistance and overuse of antibiotics indicated for empirical treatments. The population exposed to relevant risk factors should be adequately informed about the increased risk of developing infections and motivated toward the intensive use of condoms during sexual intercourses., Patient Summary: Urethritis is a sexually transmitted disease generally characterized by urethral discharge or other symptoms such as itching, tingling, and apparent difficulties in having a regular urinary flow. Microbiological investigations are mandatory to obtain satisfactory results from the treatment. Multiple antibiotic treatments are often necessary due to the high risk of multiple pathogens responsible for the disease. Similarly, sexual partners should be investigated and treated in the same way. Several risk factors such as immunodeficiency, multiple sexual partners, homo- and bisexuality, and alcohol abuse may be related to the disease. In these cases, the use of condom is strongly recommended., (Crown Copyright © 2018. Published by Elsevier B.V. All rights reserved.)

A prevalence of 3.47% of asymptomatic Chlamydia trachomatis urethritis has been previously reported among males living with HIV infection in Brazil. This study aims to assess the recurrence of C. trachomatis urethritis three years later in the same cohort of patients and analyze associated risk factors. A total of 115 male patients diagnosed with HIV infection, with no symptoms of urethritis and observed since May of 2015 in followup visits were enrolled. They had urine samplers tested by PCR for C. trachomatis and N. gonorrhoeae between February and March 2018. Results: Three of the four patients who had asymptomatic C. trachomatis urethritis three years before were recurrently positive for C. trachomatis urethritis. Two new patients were diagnosed as positives, accounting for a total asymptomatic C. trachomatis urethritis prevalence of 4.34%. The prevalence during the whole study was 5.21%. The relative risk for a new urethritis episode among those previously diagnosed with urethritis is RR=41.62 (95% CI: 9.42-183.84), p < 0.01. Patients who presented asymptomatic urethritis anytime and who were recurrently positive for C. trachomatis had a lower mean age (p<0.01). Married individuals were protected regarding asymptomatic urethritis [p<0.01, OR = 0.04 (0.005-0.4)] and had lower risk to develop recurrence [p<0.01, RR = 0.86 (0.74-0.99)]. Illicit drugs users had risk associated to asymptomatic urethritis [p=0.02, OR= 5.9 (1.03-34)] and higher risk to develop recurrence [p<0.01, RR=1.1 (1-1.22)]. Conclusion: The recurrence of asymptomatic C. trachomatis urethritis after treatment among males living with HIV infection in Brazil can be considered high and should not be neglected.

Background: Mycoplasma genitalium (MG) is a cause of urethritis. While resistance to azithromycin is increasing, routine detection of MG is not performed in Belgium, where its prevalence is unknown. The aim of this study is to determine prevalence of MG in men with urethritis., Method and Findings: An "in-house" amplification assay detecting MG was performed on urine of men with complaints of urethritis who consulted the emergency unit or the Sexually Transmitted Infection clinic of our public hospital in Brussels. Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) were tested on the same sample. A total of 187 men were tested. Prevalence of MG was 9% (95% Confidence Interval: 5 to 13.2%). CT was detected in 20%, NG in 22% and 56% of samples were negative for these three pathogens. Neither age, ethnic origin, sexual orientation nor HIV infection were associated with MG urethritis., Conclusion: M. genitalium was identified in 9% of men with complaints of urethritis indicating that amplification assay detecting MG should be implemented in routine testing for those patients.

Objectives: The increase in HIV transmissibility in non-ulcerative sexually transmitted infection is already well-established. It is estimated that symptomatic carriers of N. gonorrhoeae and C. trachomatis have a relative risk of 4.8-fold and 3.6-fold, respectively, for the sexual acquisition of HIV. This type of evaluation for asymptomatic urethritis is necessary to reinforce strategies to combat HIV transmission. This study aims to assess the prevalence of patients with asymptomatic urethritis among men diagnosed with HIV-1 and determine the risk factors associated with this infection., Methods: We enrolled a total of 115 male patients aged 18 years or older who have been diagnosed with HIV infection and have no symptoms of urethritis or other sexually transmitted infections and who have been evaluated between May and August 2015 in a follow-up visit at the Immunology Outpatient Clinic of a Brazilian University Hospital., Results: Four asymptomatic patients were positive for C. trachomatis and were considered asymptomatic carriers of urethritis. Prevalence was 3.47%. Patients who were positive for C. trachomatis urethritis had a lower mean age (p = 0.015)., Conclusion: The presence of asymptomatic sexually transmitted infection is a challenge in clinical practice. We recommend that, in outpatient practice, the habit of inquiring on previous sexual behavior to obtain more information about risks and associations with asymptomatic sexually transmitted infection, a routine physical examination and complementary tests to detect STI pathogens should be performed to discard these conditions. The development of rapid tests for this purpose should also be encouraged.

We assessed whether urethral microscopy was performed as per clinic protocol for male clinic attendees reporting contact with Neisseria gonorrhoeae (GC), urethral symptoms or given a diagnosis of epididymo-orchitis (EO) over a 12-month period (9732 patients). Prevalence of gonorrhoea in the contacts, urethral symptoms and EO groups was 50, 12.7 and 1.6%, respectively. Microscopy was performed reliably for contacts (96%), those with discharge/dysuria with evidence of urethritis on examination (98%), but not those with EO (43%). We explored the clinical utility of microscopy as a point-of-care test for identifying urethral GC in each subgroup, using the APTIMA Combo 2 CT/GC nucleic acid amplification test as the comparator (1710 patients). Sensitivity of microscopy for each subgroup was good; there was no statistical difference between subgroup sensitivity using Fisher's exact test. Microscopy is valuable to ensure prompt diagnosis and contact tracing. All GC contacts were treated 'epidemiologically'; however, half of GC contacts did not have GC. Microscopy identified the majority of GC cases, including amongst contacts (71% of heterosexual contacts, 66% of contacts reporting sex with men). We propose that epidemiological treatment for GC contacts should be reconsidered on the grounds of antibiotic stewardship, favouring use of microscopy to guide treatment decisions.

Background: We aimed to evaluate the prevalence of sexually transmitted infections (STI, including Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis) among high-risk heterosexual male patients and to clarify their potency to cause complaints and inflammation., Methods: The study group included 825 men (18.0-49.5 y) consulting andrologist at Tartu University Hospital (Estonia) due to subjectively perceived risk of STI. Patients completed STI risk behaviour questionnaire. First voided urine was analysed for white blood cells and STIs., Results: In total 193 (23.4%) patients were positive for one or multiple STI. The prevalence of C. trachomatis, M. genitalium, N. gonorrhoeae, T. vaginalis and combined STI was 14.3%, 4.4%, 2.7%, 0.7% and 1.3%, respectively. N. gonorrhoeae had the highest potency to generate inflammatory reaction in first voided urine (100%) followed by C. trachomatis (72.0%), M. genitalium (63.9%) and T. vaginalis (33.3%). N. gonorrhoeae and T. vaginalis caused the highest mean number of complaints while half of T. vaginalis cases and nearly fifth of M. genitalium and C. trachomatis cases were asymptomatic., Conclusions: C. trachomatis has the highest prevalence among Estonian high-risk men but M. genitalium holds an important second place. Prevalence of combined STIs is low. N. gonorrhoeae has the highest potency to generate urethral inflammation followed by C. trachomatis and M. genitalium. The highest number of complaints is also associated with N. gonorrhoeae while half of T. vaginalis cases and nearly a fifth of M. genitalium and C. trachomatis cases are asymptomatic.

The objective was to determine whether or not the limited use of urethral microscopy to diagnose asymptomatic and symptomatic non-chlamydial, non-gonococcal urethritis (NCNGU) in men is a cost-effective strategy to avert pelvic inflammatory disease (PID), ectopic pregnancy or infertility in female partners. Outputs from a transmission dynamic model of NCNGU in a population of 16-30 year olds in England simulating the number of consultations, PID cases and patients treated over time amongst others, were used along with secondary data to undertake a cost-effectiveness analysis carried out from a health care provider perspective. The main outcome measure was cost per case of PID averted. A secondary outcome measure was cost per major outcome averted, where a major outcome is a case of symptomatic PID, ectopic pregnancy, or infertility. Offering a limited number of asymptomatic men urethral microscopy was more effective than the current practice of no microscopy in terms of reducing the number of cases of PID with an incremental cost-effectiveness ratio of £15,700, meaning that an investment of £15,800 is required to avert one case of PID. For major outcomes averted, offering some asymptomatic men urethral microscopy was again found to be more effective than no microscopy, but here an investment of £49,900 is required to avert one major outcome. Testing asymptomatic men for NCNGU in a small number of genitourinary medicine settings in England is not cost-effective, and thus by maintaining the current practice of not offering this patient group microscopy, this continues to make savings for the health care provider.

Background: Men who have sex with men (MSM) are a key population, particularly vulnerable to sexually transmitted infections (STIs) and HIV, but there are limited data on health programs targeting MSM in Africa. This study aims to describe the utilization of nongovernmental organization-supported sexual health services for MSM at 2 public sector health facilities in Johannesburg, South Africa., Methods: We retrospectively analyzed routine data over the period of January 2014 to June 2016. We report on service utilization for STI syndromes, HIV testing, and the antiretroviral therapy (ART) program., Results: Some 5796 men visited the facilities. Seven thousand one hundred eighty-eight STI episodes were managed, 68.2% (4903 episodes) of which were classified as male urethritis and 9.8% (704 episodes) as genital ulcers. Positivity yield for first-time HIV tests was 38.0% (205 positive test results) in MSM, compared with 14.1% (471 positive test results) in other men. At the end of the study, there were 1090 clients on ART, and 2-year retention was 82% (95% confidence interval, 78%-85%). There was no difference in retention between MSM and other men (P = 0.49)., Conclusions: This study is the first to show that sexual health services targeting MSM in Africa have managed to attract MSM and other men in need of STI and HIV care. The observed high HIV testing yield among MSM illustrates the relevance of MSM-focused services in the South African public health sector, and the good retention on ART demonstrates that high-quality care can be provided to MSM in our setting.

Objective: Previous studies have quantified bacterial loads of Neisseria gonorrhoeae in the pharynx and rectum of men but not the urethra. We quantified the bacterial load of N. gonorrhoeae in men with symptomatic and asymptomatic urethral gonorrhoea infections., Methods: Consecutive men diagnosed with urethral gonorrhoea by Aptima Combo 2 testing of urine at the Melbourne Sexual Health Centre between March and July 2016 were eligible for the study: symptomatic men with purulent urethral discharge and asymptomatic men with no urethral symptoms. The gonococcal bacterial load in both groups was measured by urethral swab using a standardised collection method and real-time quantitative PCR targeting the opa gene., Results: Twenty men were recruited into the study: 16 had purulent urethral discharge and 4 had asymptomatic urethral gonorrhoea. The median gonococcal bacterial load was significantly higher among symptomatic men (3.7×10 6 copies per swab, IQR 2.5×10 6 -4.7×10 6 ) compared with asymptomatic men (2.0×10 5 copies per swab, IQR 2.7×10 4 -4.5×10 5 ) (p=0.002)., Conclusions: Gonococcal loads in men with urethral discharge were higher than loads seen with asymptomatic urethral gonorrhoea and loads seen in asymptomatic pharyngeal and rectal gonorrhoea infections in previous studies., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

Objectives: Guidelines regarding whether men who have sex with men (MSM) without symptoms of urethritis should be screened for urethral gonorrhoea differ between countries. We examined the rate of asymptomatic urethral gonorrhoea in MSM using sensitive nucleic acid amplification testing., Methods: This study was conducted on consecutive MSM attending the Melbourne Sexual Health Centre between July 2015 and May 2016 for sexually transmitted infections screening. Gonorrhoea testing with the Aptima Combo 2 (AC2) assay was performed on all urine specimens obtained from MSM, whether symptoms of urethritis were present or not. Men were classified as having: typical discharge if they reported symptoms suggesting purulent discharge; other symptoms if they reported other symptoms of urethritis; and no symptoms if they reported no urethral symptoms., Results: During the study period, there were 7941 clinic visits by 5947 individual MSM with 7090 urine specimens obtained from 5497 individual MSM tested with the AC2 assay. Urethral gonorrhoea was detected in 242 urine specimens from 228 individual MSM. The majority (189/242, 78%, 95% CI 73-83) reported typical discharge, 27/242 (11%, 95% CI 8-16) reported other urethral symptoms, and 26/242 (11%, 95% CI 7-15) reported no symptoms on the day of presentation and testing. Among men with urethral gonorrhoea, the proportions with concurrent pharyngeal or rectal gonorrhoea were 32% (134/210) and 64% (74/235), respectively. The mean interval between last reported sexual contact and onset of typical urethral discharge, where present, was 3.9 days., Conclusion: The findings from our study lend support to guidelines that recommend screening asymptomatic MSM for urethral gonorrhoea., (Copyright © 2017 European Society of Clinical Microbiology and Infectious Diseases.

Background: Macrolide and fluoroquinolone resistance is alarmingly emerging in M. genitalium worldwide. This article provides the first estimates of the current prevalence of macrolide and fluoroquinolone resistance-mediating mutations in Barcelona, Spain, and identifies risk factors associated with the acquisition of these resistances., Methods: The study was conducted retrospectively with specimens submitted between February 2013 and March 2014 to the microbiology department of the Vall d'Hebron Hospital, Barcelona, where M. genitalium was detected using nucleic acid amplification methods. DNA sequencing of 23S ribosomal RNA gene and parC was performed in the Statens Serum Institut, Copenhagen, to detect genotypic macrolide and fluoroquinolone resistance markers, respectively., Results: Macrolide resistance-mediating mutations were detected in 35% (95% confidence interval, 24%-47%) of the M. genitalium-positive episodes, whereas 8% (95% confidence interval, 3%-17%) carried fluoroquinolone resistance mutations. Of them, three cases harbored multidrug resistance to both classes of antibiotics. Men who had sex with men (P = 0.002) and treatment with azithromycin within the previous 12 months (P = 0.006) were strongly associated with macrolide resistance., Conclusion: The widespread appearance of resistances, also in Spain, makes imperative the implementation of combined diagnostic-resistance detection assays for M. genitalium to facilitate the optimization of antibiotic treatment in the management of nongonococcal urethritis and potentially reduce the transmission of resistances.

Background: Neisseria meningitidis (Nm) is a Gram-negative diplococcus that normally colonizes the nasopharynx and rarely infects the urogenital tract. On Gram stain of urethral exudates, Nm can be misidentified as the more common sexually transmitted pathogen Neisseria gonorrhoeae., Methods: In response to a large increase in cases of Nm urethritis identified among men presenting for screening at a sexually transmitted disease clinic in Columbus, Ohio, we investigated the epidemiologic characteristics of men with Nm urethritis and the molecular and phylogenetic characteristics of their Nm isolates. The study was conducted between 1 January and 18 November 2015., Results: Seventy-five Nm urethritis cases were confirmed by biochemical and polymerase chain reaction testing. Men with Nm urethritis were a median age of 31 years (interquartile range [IQR] = 24-38) and had a median of 2 sex partners in the last 3 months (IQR = 1-3). Nm cases were predominantly black (81%) and heterosexual (99%). Most had urethral discharge (91%), reported oral sex with a female in the last 12 months (96%), and were treated with a ceftriaxone-based regimen (95%). A minority (15%) also had urethral chlamydia coinfection. All urethral Nm isolates were nongroupable, ST-11 clonal complex (cc11), ET-15, and clustered together phylogenetically. Urethral Nm isolates were similar by fine typing (PorA P1.5-1,10-8, PorB 2-2, FetA F3-6), except 2, which had different PorB types (2-78 and 2-52)., Conclusions: Between January and November 2015, 75 urethritis cases due to a distinct Nm clade occurred among primarily black, heterosexual men in Columbus, Ohio. Future urogenital Nm infection studies should focus on pathogenesis and modes of sexual transmission., (© The Author 2017.

A non-syndromic approach to treatment of people with non-gonococcal urethritis (NGU) requires identification of pathogens and understanding of the role of those pathogens in causing disease. The most commonly detected and isolated micro-organisms in the male urethral tract are bacteria belonging to the family of Mycoplasmataceae, in particular Ureaplasma urealyticum and Ureaplasma parvum. To better understand the role of these Ureaplasma species in NGU, we have performed a prospective analysis of male patients voluntarily attending a drop in STI clinic in Oslo. Of 362 male patients who were tested for NGU using microscopy of urethral smears, we found the following sexually transmissible micro-organisms: 16% Chlamydia trachomatis, 5% Mycoplasma genitalium, 14% U. urealyticum, 14% U. parvum and 5% Mycoplasma hominis. We found a high concordance in detecting in turn U. urealyticum and U. parvum using 16s rRNA gene and ureD gene as targets for nucleic acid amplification testing (NAAT). Whilst there was a strong association between microscopic signs of NGU and C. trachomatis infection, association of M. genitalium and U. urealyticum infections in turn were found only in patients with severe NGU (>30 polymorphonuclear leucocytes, PMNL/high powered fields, HPF). U. parvum was found to colonise a high percentage of patients with no or mild signs of NGU (0-9 PMNL/HPF). We conclude that urethral inflammatory response to ureaplasmas is less severe than to C. trachomatis and M. genitalium in most patients and that testing and treatment of ureaplasma-positive patients should only be considered when other STIs have been ruled out.

Recommendations for the treatment of lower non-catheter-related urinary tract infection (UTI) in men are rarely evidence-based. Their management requires the localization of the site of infection, whether it be the urethra, bladder or prostate, and includes antibiotic therapy and in most cases urological assessment. They are often associated with urinary tract procedures or anatomical or functional abnormalities. Nearly 80 % of male UTIs are caused by Enterobacteriaceae. The prevalence of broad-spectrum beta-lactamase-producing strains (ESBL) and quinolone-resistant strains is increasing. The aim of this article is to define three types of lower, non-catheter-related UTI in men - urethritis, cystitis and prostatitis - their microbiology and management in Switzerland., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

At a clinic in Indianapolis, Indiana, USA, we observed an increase in Neisseria gonorrhoeae-negative men with suspected gonococcal urethritis who had urethral cultures positive for N. meningitidis. We describe genomes of 2 of these N. meningitidis sequence type 11 complex urethritis isolates. Clinical evidence suggests these isolates may represent an emerging urethrotropic clade.

Background: We evaluated the impact of extended azithromycin (1.5g over 5 days) on selection of macrolide resistance and microbiological cure in men with Mycoplasma genitalium urethritis during 2013-2015 and compared this to cases treated with azithromycin 1g in 2012-2013., Methods: Microbiological cure was determined for men with M. genitalium urethritis treated with azithromycin 1.5g using quantitative polymerase chain reaction specific for M. genitalium DNA on samples 14-100 days post-treatment. Pre- and post-treatment macrolide resistance mutations were detected by sequencing the 23 S gene., Results: There was no difference in proportions with microbiological cure between azithromycin 1.5g and 1g: 62/106 (58%; 95% confidence interval [CI], 49%, 68%) and 56/107 (52%; 95%CI 42-62%), P = .34, respectively. Also, there was no difference in the proportion of wild-type 23 S rRNA (presumed macrolide sensitive) infections cured after 1.5g and azithromycin 1g: 28/34 (82%; 95%CI 65-92%) and 49/60 (82%; 95%CI 70-90%), P=1.0, respectively. There was no difference between 1.5g and 1g in the proportions of wild-type infections with post-treatment resistance mutations: 4/34 (12%; 95%CI 3-27%) and 11/60 (18%; 95%CI 10-30%), respectively, P = .40. Pre-treatment resistance was present in 51/98 (52%; 95%CI 42-62%) cases in 2013-2015 compared to 47/107 (44%; 95%CI 34-54%) in 2012-2013, P = .25., Conclusions: Extended azithromycin 1.5g was no more effective than a single 1g dose at achieving cure of M. genitalium urethritis and importantly did not reduce the selection of macrolide resistance. Nonmacrolide and new approaches for the treatment of M. genitalium urethritis are required., (© The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

We sought to investigate the prevalence of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in men presenting to a sexually transmitted infection (STI) clinic, with special attention to M. genitalium, its occurrence in Israeli patients, coinfections, and risk factors. In a cross-sectional study, 259 men were successively enrolled in the Tel Aviv Levinsky Clinic for STIs between November 2008 and November 2010. There were 118 men with urethritis and 141 high-risk men without symptoms. M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis were detected using nucleic acid amplification tests. Demographic characteristics and risk factors were documented. The overall prevalence of infection with M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis, were 6.6%, 12.7%, 23.1%, and 0%, respectively. Prevalences in men with urethritis were 11.9%, 22%, and 49%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Prevalences in men without symptoms were 2.1%, 5.0%, and 1.4%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Co-infections were found only in symptomatic individuals, in whom 5.9% were infected concomitantly with C. trachomatis and N. gonorrhoeae, and 2.5% had dual infection with M. genitalium and N. gonorrhoeae. N. gonorrhoeae, C. trachomatis, and M. genitalium were significantly more prevalent in patients with urethritis. M. genitalium was significantly more prevalent in the heterosexual population than in homosexual males. To conclude, we have found that M. genitalium infection is associated with urethritis in Israeli men, and more so in the heterosexual population. Testing men for M. genitalium as a cause of non-gonococcal urethritis is warranted, particularly because of its poor response to doxycycline and possible failure of azithromycin.

Objectives: This study was designed to evaluate the causative organisms in young male soldiers with clinical signs and symptoms after sexual contact that suggests a diagnosis of urethritis., Methods: Between June 2012 and January 2015, male patients with urethritis symptoms that had resulted from sexual contact within 3 months participated in this study. All patients were evaluated using urinalysis and were screened for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), Mycoplasma genitalium (MG), Mycoplasma hominis (MH), herpes simplex virus (HSV) type II and Trichomonas vaginalis (TV) using multiplex PCR (mPCR) assay in order to detect sexually transmitted infections (STI) or pathogens., Results: A total of 436 male patients aged 18-28 years were included in the study. The median age was 22.0 years. The prevalence of STI pathogens were as follows: NG in 19.0%, CT in 36.6%, UU in 24.0%, MG in 21.5%, MH in 6.1%, HSV type II in 1.6%, TV in 0.2% and indeterminate STI pathogens in 9.4%. Coinfection of NG with non-NG was detected in 5.7% of the participants, while the coinfection rates for STI pathogens were: with CT in 3.4%, with UU in 2.7%, with MG in 0.2% and with MH in 0.2%., Conclusions: CT was the most prevalent STI pathogen and coinfections of NG with non-NG appeared less frequently. The young male soldiers with urethritis should be administered suitable antibiotics for STI pathogens that were found by mPCR results, rather than an experimental combination of antibiotics for coinfections., (Published by the BMJ Publishing Group Limited.

Background: This study was done to diagnose Mycoplasma genitalium infection based on bacterial load in urine specimens from symptomatic and asymptomatic men., Methods: Urine specimens from 94 men with visible urethral discharge, 206 with burning on micturition and 75 without symptoms presenting to a family practitioner were tested for M. genitalium as well as Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis by transcription-mediated amplification assays. A quantitative polymerase chain reaction assay was used to determine the bacterial load for all specimens in which M. genitalium was the only organism detected., Results: Among the 375 specimens collected, M. genitalium was detected in 59 (15.7%) men (both symptomatic and asymptomatic) using the transcription-mediated amplification assay, and in 45 (12.0%) of the total population, it was the only pathogen detected. One or more pathogens were detected in 129 (43%) of the symptomatic men, with N. gonorrhoeae in 50 (16.7%); C. trachomatis in 37 (12.3%) and T. vaginalis present in 24 (8.0%) patients. Among the 17 patients where mixed infections were detected, M. genitalium with N. gonorrhoeae was the most common (11/17; 64.7%). Patients with visible urethral discharge had significantly higher M. genitalium concentrations than those with burning on micturition. The median M. genitalium load in symptomatic men was significantly higher than that in asymptomatic men., Conclusions: This study confirms the high prevalence of M. genitalium among men with urethritis in South Africa and demonstrates that there is a strong association with M. genitalium bacterial load and clinical urethritis. As the number of organisms increased, the severity of the symptoms increased, an indication of the role that the organism plays in disease progression.

Background: Point-of-care (POC) tests are an important strategy to address the epidemic of sexually transmitted infections (STIs). The leucocyte esterase test (LET) can be used as a POC test for chlamydia. The aim of this study was to determine the diagnostic accuracy of the LET to detect urogenital chlamydia among men at STI clinics in Paramaribo, Suriname and Amsterdam, the Netherlands., Methods: Recruitment of patients took place in 2008-2010 in Suriname and in 2009-2010 in the Netherlands. Urine of patients was examined with the LET. The reference test was a nucleic acid amplification test (NAAT)., Results: We included 412 patients in Suriname and 645 in the Netherlands. Prevalence of chlamydia in Suriname and the Netherlands was respectively 22.8 and 13.6 %. The sensitivity of the LET was 92.6 % (95 % CI = 85.3-97.0) and 77.3 % (95 % CI = 67.1-85.5) respectively, the specificity was 38.1 % (95 % CI = 32.7-43.6 %) and 58.1 % (95 % CI = 53.9-62.3) respectively. The positive predictive value was 30.6 % (95 % CI = 27.3-36.4) and 22.6 % (95 % CI = 18.0-27.7) respectively and the negative predictive value was 94.5 % (95 % CI = 89.1-97.8) and 94.2 % (95 % CI = 91.1-96.4) respectively. The kappa was respectively 0.179 and 0.176., Conclusions: To diagnose urogenital chlamydia in men the LET performs poorly. It has a high negative but low positive predictive value. If the LET result is negative, chlamydia is accurately excluded, yet a positive result has a low predictive value. Whether the advantages of direct management based on LET outweigh the disadvantages of overtreatment is a subject for further studies.

Inflammation of the urethra defined by an excess of polymorphonuclear leukocytes in the absence of sexually transmitted Chlamydia trachomatis and Neisseria gonorrhoeae is called non-chlamydial non-gonococcal urethritis (NCNGU). Although Mycoplasma genitalium is now recognised as causing a sexually transmitted infection, the clinical significance of the other Mollicute species is less clear. This study used specific real-time quantitative polymerase chain reaction assays to detect and quantify four Mollicute species, M. genitalium, M. hominis, Ureaplasma urealyticum and U. parvum, in urine specimens from men with and without NCNGU. A total of 165 urine specimens from male patients attending a genitourinary medicine clinic were eligible for the study, with microscopy-confirmed (≥5 polymorphonuclear leukocytes in urethral swab) NCNGU in 75 (45.5%) and non-confirmed NCNGU in 90 (54.5%). Chi-squared statistical analysis indicated a significantly higher prevalence of U. parvum (17.3% vs. 5.6%; p = 0.03) and M. genitalium (12% vs. 0%; p < 0.001) in NCNGU. In a subset analysis, M. genitalium was also significantly (p = 0.03) higher in men who have sex with men (MSM; 13.5%) compared to non-MSM (3.1%). No significant associations were reported for U. urealyticum and M. hominis In conclusion, this study supports a clinically significant role in NGNCU for both U. parvum and M. genitalium., (© The Author(s) 2015.)

Introduction: Sexually transmitted infections (STIs) are commonly seen in the ambulatory health care settings such as emergency departments (EDs) and outpatient clinics. Our objective was to assess trends over time in the incidence and demographics of STIs seen in the ED and outpatient clinics compared with office-based clinics using the National Hospital Ambulatory Medical Care Survey and National Ambulatory Medical Care Survey., Methods: This study was conducted using 10 years of National Hospital Ambulatory Medical Care Survey and National Ambulatory Medical Care Survey data (2001-2010). We compared data from 2001-2005 to data from 2006-2010. Patients were included in analyses if they were 15 years and older and had an International Classification of Diseases, Ninth Revision code consistent with cervicitis, urethritis, chlamydia, gonorrhea, or trichomonas., Results: We analyzed 82.4 million visits for STIs, with 16.5% seen in hospital-based EDs and 83.5% seen in office-based clinics between 2001 and 2010. Compared with patients seen in office-based clinics, ED patients were younger (P< .05), more likely to be male (P< .001) and nonwhite (P< .001), and less likely to have private insurance (P< .05). We found a significant increase in adolescent (15-18 years) ED visits (P< .05) from 2001-2015 to 2006-2010 and a decrease in adolescent and male STI visits in office-based settings (P< .05)., Conclusion: Although patients with STI are most commonly seen in office-based clinics, EDs represent an important site of care. In particular, ED patients are relatively younger, male, and nonwhite, and less likely to be private insured., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Neisseria meningitidis (Nm) urogenital infections, although less common than infections caused by Neisseria gonorrhoeae (Ng), have been associated with urethritis, cervicitis, proctitis, and pelvic inflammatory disease. Nm can appear similar to Ng on Gram stain analysis (gram-negative intracellular diplococci) (1-5). Because Nm colonizes the nasopharynx, men who receive oral sex (fellatio) can acquire urethral Nm infections (1,3,5). This report describes an increase in Nm-associated urethritis in men attending sexual health clinics in Columbus, Ohio, and Oakland County, Michigan.

This cross-sectional study investigated the prevalence, genotypes, and risk factors for human papillomavirus (HPV) infection in Hanoi, Vietnam. The study included 192 males (mean age, 32.9 years) with symptoms related to sexually transmitted infections (STI). Urinary, penile, and urethral samples were collected in April and May, 2014. HPV DNA was detected with PCR, performed with modified and/or original GP5(+)/GP6(+) primers. HPV genotypes were determined with a gene array assay. Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) DNA were detected with loop-mediated isothermal amplification. HPV DNA, NG, and CT were detected in 48 (25.0%), 23 (12.0%), and 41 (21.4%) patients, respectively. HPV DNA appeared in penile samples (21.0%, 39/186) more frequently than in urinary (3.1%, 6/191, P < 0.001) and urethral (9.4%, 18/192, P = 0.002) samples. Among patients with HPV, genotype prevalence was: HPV81 (22.9%),  HPV52 (18.8%), HPV18 (16.7%), and HPV16 (6.3%). Multiple-type and high risk-type HPV infections were determined in 33.3% and 64.6%, respectively. Multivariate analysis showed a significant association of HPV infection in urethra with younger sexual debut age. HPV52 was the most prevalent high-risk HPV genotype, whereas HPV16 was less common in the male Vietnamese patients with STI-related symptoms. Younger sexual-debut age was a risk factor for HPV infection in urethra., (© 2015 Wiley Periodicals, Inc.)

Meningococci spread via respiratory droplets, whereas the closely related gonococci are transmitted sexually. Several outbreaks of invasive meningococcal disease have been reported in Europe and the United States among men who have sex with men (MSM). We recently identified an outbreak of serogroup C meningococcal disease among MSM in Germany and France. In this study, genomic and proteomic techniques were used to analyze the outbreak isolates. In addition, genetically identical urethritis isolates were recovered from France and Germany and included in the analysis. Genome sequencing revealed that the isolates from the outbreak among MSM and from urethritis cases belonged to a clade within clonal complex 11. Proteome analysis showed they expressed nitrite reductase, enabling anaerobic growth as previously described for gonococci. Invasive isolates from MSM, but not urethritis isolates, further expressed functional human factor H binding protein associated with enhanced survival in a newly developed transgenic mouse model expressing human factor H, a complement regulatory protein. In conclusion, our data suggest that urethritis and outbreak isolates followed a joint adaptation route including adaption to the urogenital tract.

Background: The aim of this study was to characterise the clinical features of adenovirus urethritis in men and to compare the frequency of these between heterosexual men and men who have sex with men (MSM)., Methods: This was a review of the clinical and laboratory information from men diagnosed with PCR-confirmed adenovirus urethritis at the Melbourne Sexual Health Centre between January 2006 and April 2014., Results: 102 adenovirus urethritis cases were reported, among which 61 were heterosexual men and 41 MSM. Eighty-nine per cent (n=91) had signs of meatitis or conjunctivitis: 51% had meatitis only; 32% meatitis together with conjunctivitis and 6% with conjunctivitis only. The distribution of symptoms and signs was similar among heterosexual men and MSM (p values >0.1). Adenovirus was the sole pathogen found in 93% of cases, excluding gonorrhoea, chlamydia, Mycoplasma genitalium and herpes simplex virus. Only 37% had ≥5 polymorphs per high-power field from a urethral smear. Where samples were still available for adenoviral sequencing (n=20), all were subgroup D., Conclusions: The clinical features of adenovirus urethritis in men can be distinctive and aid diagnosis, distinguishing it from other treatable causes of male urethritis., (Published by the BMJ Publishing Group Limited.

Objectives: To detect microorganisms responsible for male acute urethritis and to define the microbiology of non-gonococcal urethritis., Methods: The present study comprised 424 men with symptoms and signs compatible with acute urethritis. Their urethral swabs and first-voided urine underwent detection of the microorganisms. Demographic characteristics and clinical features of Mycoplasma genitalium-, Ureaplasma urealyticum-, Haemophilus influenza-, adenovirus- or Herpes simplex virus-positive monomicrobial non-gonococcal urethritis, or all-examined microorganism-negative urethritis in heterosexual men were compared with urethritis positive only for Chlamydia trachomatis., Results: Neisseria gonorrhoeae was detected in 127 men (30.0%). In 297 men with non-gonococcal urethritis, C. trachomatis was detected in 143 (48.1%). In 154 men with non-chlamydial non-gonococcal urethritis, M. genitalium (22.7%), M. hominis (5.8%), Ureaplasma parvum (9.1%), U. urealyticum (19.5%), H. influenzae (14.3%), Neisseria meningitidis (3.9%), Trichomonas vaginalis (1.3%), human adenovirus (16.2%), and Herpes simplex virus types 1 (7.1%) and 2 (2.6%) were detected. Although some features of monomicrobial non-chlamydial non-gonococcal urethritis or all-examined microorganism-negative urethritis were significantly different from those of monomicrobial chlamydial non-gonococcal urethritis, most features were superimposed., Conclusions: Predicting causative microorganisms in men with non-gonococcal urethritis based on demographic and clinical features is difficult. However, the present study provides useful information to better understand the microbiological diversity in non-gonococcal urethritis, and to manage patients with non-gonococcal urethritis appropriately., (© 2016 The Japanese Urological Association.)

Purpose: We relied on a population-based case-control study (PROtEuS) to examine a potential association between the presence of histologically confirmed prostate cancer (PCa) and history of genitourinary infections, e.g., prostatitis, urethritis, orchitis and epididymitis., Patients and Methods: Cases were 1933 men with incident PCa, diagnosed across Montreal hospitals between 2005 and 2009. Population controls were 1994 men from the same residential area and age distribution. In-person interviews collected information about socio-demographic characteristics, lifestyle and medical history, e.g., self-reported history of several genitourinary infections, as well as on PCa screening. Logistic regression analyses tested overall and grade-specific associations, including subgroup analyses with frequent PSA testing., Results: After multivariable adjustment, prostatitis was associated with an increased risk of any PCa (OR 1.81 [1.44-2.27]), but not urethritis (OR 1.05 [0.84-1.30]), orchitis (OR 1.28 [0.92-1.78]) or epididymitis (OR 0.98 [0.57-1.68]). The association between prostatitis and PCa was more pronounced for low-grade PCa (Gleason ≤ 6: OR 2.11 [1.61-2.77]; Gleason ≥ 7: OR 1.59 [1.22-2.07]). Adjusting for frequency of physician visits, PSA testing frequency or restricting analyses to frequently screened subjects did not affect these results., Conclusion: Prostatitis was associated with an increased probability for detecting PCa even after adjustment for frequency of PSA testing and physician visits, but not urethritis, orchitis or epididymitis. These considerations may be helpful in clinical risk stratification of individuals in whom the risk of PCa is pertinent.

Background: Sexually transmitted infections (STIs) of the pharynx are common among men who have sex with men (MSM); the degree to which these infections are transmitted through oral sex is unknown., Methods: We conducted a case-control study of MSM attending Public Health-Seattle & King County STD Clinic between 2001 and 2013 to estimate the proportion of symptomatic urethritis cases attributable to oral sex using two methods. First, we categorised men into the following mutually exclusive behavioural categories based on their self-reported sexual history in the previous 60 days: (1) only received oral sex (IOS); (2) 100% condom usage with insertive anal sex plus oral sex (PIAI); (3) inconsistent condom usage with anal sex (UIAI); and (4) no sex. We then determined the proportion of cases in which men reported the oropharynx as their only urethral exposure (IOS and PIAI). Second, we calculated the population attributable risk per cent (PAR%) associated with oral sex using Mantel-Haenszel OR estimates., Results: Based on our behavioural categorisation method, men reported the oropharynx as their only urethral exposure in the past 60 days in 27.5% of gonococcal urethritis, 31.4% of chlamydial urethritis and 35.9% non-gonococcal, non-chlamydial urethritis (NGNCU) cases. The PAR%s for symptomatic gonococcal urethritis, chlamydial urethritis and NGNCU attributed to oropharyngeal exposure were 33.8%, 2.7% and 27.1%, respectively., Conclusions: The pharynx is an important source of gonococcal transmission, and may be important in the transmission of chlamydia and other, unidentified pathogens that cause urethritis. Efforts to increase pharyngeal gonorrhoea screening among MSM could diminish STI transmission., (Published by the BMJ Publishing Group Limited.

Background: Men are not routinely tested for Trichomonas vaginalis (TV) and Mycoplasma genitalium (MG) in the Netherlands and, therefore, very few studies have looked into their prevalence and/or role in urogenital complaints in the Dutch male population., Objective: To describe the age-specific prevalence and disease burden of TV and MG, and their co-occurrence with Chlamydia trachomatis (CT), in men attending the sexually transmitted infections (STI) clinic in Amsterdam, the Netherlands., Methods: Urine samples and clinical data were collected from 526 men who have sex with women (MSW) and 678 men who have sex with men (MSM) attending the STI clinic. To investigate age as a risk factor, we oversampled older men. Urine samples were tested for TV and MG using molecular tests., Results: The overall prevalence was 0.5% (6/1204) for TV and 3.1% (37/1204) for MG. Four out of the six TV cases were older than 40 years and all TV cases were MSW. No age trend was observed for MG, nor did MG prevalence differ between MSW and MSM. Co-infections between TV or MG and CT were rare. TV infection did not associate with urogenital symptoms, whereas 5.9% of men reporting urogenital symptoms were infected with MG., Conclusions: TV infection was rare in men, asymptomatic and was limited to the heterosexual network. MG infection was relatively common and equally prevalent among MSW and MSM of all ages. Most MG infections remained asymptomatic, however, our results suggest that up to 6% of urogenital complaints could be explained by MG infection., (Published by the BMJ Publishing Group Limited.

Persistent or recurrent non-gonococcal urethritis has been reported to affect up to 10-20% of men attending sexual health clinics. An audit was undertaken to review the management of persistent or recurrent non-gonococcal urethritis in men presenting at Whittall Street Clinic, Birmingham, UK. Detection of Trichomonas vaginalis infection was with the newly-introduced nucleic acid amplification test. A total of 43 (8%) of 533 men treated for urethritis re-attended within three months with persistent or recurrent symptoms. Chlamydia trachomatis infection was identified in 13/40 (33%), T. vaginalis in 1/27 (4%) and Mycoplasma genitalium in 6/12 (50%). These findings suggest that the prevalence of T. vaginalis infection remains low in our clinic population and may not contribute significantly to persistent or recurrent non-gonococcal urethritis., (© The Author(s) 2015.)

The prevalence of urogenital mycoplasmas in men with NGU in Upper Silesia (Poland) was studied. Mycoplasmas were detected in 36.7% men (Ureaplasma parvum and Mycoplasma genitalium were found in 30% and 16.7% respectively). Urealyticum urealyticum was not detected. We suggest including M. genitalium in the diagnostic scheme for nongonococcal urethritis (NGU).

Ureaplasma parvum, which has been recognised as a coloniser in the male urethra, is detected in some men with non-gonococcal urethritis. In this study, we quantified the 16 S rRNA genes of U. parvum by a real-time polymerase chain reaction-based assay in first-voided urine from 15 symptomatic and 38 asymptomatic men who were positive only for U. parvum. We also determined the leukocyte counts by automated quantitative urine particle analysis in their first-voided urine. Positive correlations were observed between copies of the 16 S rRNA genes of U. parvum/ml and the leukocyte counts/µl in first-voided urine (p = 0.0019). The loads of ≥10(4) copies of the 16 S rRNA gene/ml, corresponding to ≥5 × 10(3) cells of U. parvum/ml, were significantly associated with the presence of ≥12.5 leukocytes/µl in first-voided urine that might document the presence of inflammatory responses in the urethra. However, a large portion of the subjects (83.0%) had bacterial loads of <5 × 10(3) cells of U. parvum/ml, and 79.5% of them showed <12.5 leukocytes/µl. The ambiguity of the pathogenic role of U. parvum in non-gonococcal urethritis could, in part, be due to its low bacterial loads, which might not give rise to inflammatory responses in the male urethra., (© The Author(s) 2015.)

Background: There are currently no large general population epidemiological studies of Mycoplasma genitalium (MG), which include prevalence, risk factors, symptoms and co-infection in men and women across a broad age range., Methods: In 2010-–12, we conducted the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a probability sample survey in Britain. Urine from 4507 sexually-experienced participants, aged 16–44 years, was tested for MG., Results: MG prevalence was 1.2% [95% confidence interval (CI): 0.7–1.8%] in men and 1.3% (0.9–1.9%) in women. There were no positive MG tests in men aged 16–19, and prevalence peaked at 2.1% (1.2–3.7%) in men aged 25–34 years. In women, prevalence was highest in 16–19 year olds, at 2.4% (1.2–4.8%), and decreased with age. Men of Black ethnicity were more likely to test positive for MG [adjusted odds ratio (AOR) 12.1; 95% CI: 3.7–39.4). For both men and women, MG was strongly associated with reporting sexual risk behaviours (increasing number of total and new partners, and unsafe sex, in the past year). Women with MG were more likely to report post-coital bleeding (AOR 5.8; 95%CI 1.4–23.3). However, the majority of men (94.4%), and over half of women (56.2%) with MG did not report any sexually transmitted infection (STI) symptoms. Men with MG were more likely to report previously diagnosed gonorrhoea, syphilis or non-specific urethritis, and women previous trichomoniasis., Conclusions: This study strengthens evidence that MG is an STI. MG was identified in over 1% of the population, including in men with high-risk behaviours in older age groups that are often not included in STI prevention measures.

Objectives: The main objective of this study is to determine the prevalence of trichomoniasis in men with and without symptoms of urethritis, with concomitant analysis of sociodemographic and behavioural specificities of both groups. Also, the objective is to evaluate laboratory methods used in the diagnostics of this parasitic disease., Methods: A total of 500 men with and 200 without urethritis symptoms were included in the study. Every respondent filled out a questionnaire asking for some general data, specific information about habits, sexual behaviour and symptoms. Sediment of first void urine was analysed by wet mount microscopy, cultivation in Diamond's medium and real-time PCR., Results: In the symptomatic group, Trichomonas vaginalis infection was documented in 2.4% of respondents by wet mount microscopy, in 4.8% by cultivation and in 8.2% by real-time PCR. In the asymptomatic group, infection was proven using the same methods in 1.0%, 1.5% and 2.0% of the respondents, respectively. Trichomoniasis prevalence was statistically significantly higher in the respondents manifesting urethritis symptoms when cultivation (χ2=4.20, p=0.041) and real-time PCR (χ2=9.20, p=0.002) were used. Several epidemiological risk factors were identified, and greater sensitivity of real-time PCR was found in comparison with microscopy and culture., Conclusions: Trichomonas infection was statistically more frequent in men with urethritis syndrome. Assuming that the samples found positive by any laboratory technique are truly positive, it can be concluded that the real-time PCR showed the greatest sensitivity of all the methods used in this study., (Published by the BMJ Publishing Group Limited.

A total of 2750 male urines subjected to a transcription-mediated amplification (TMA)-based Mycoplasma genitalium assay yielded 188 positive results (6.84%). This rate was similar to Chlamydia trachomatis (6.87%; P = 0.96) and greater than Neisseria gonorrhoeae (4.0%) and Trichomonas vaginalis (2.3%; P < 0.0002). Mean age of M. genitalium-infected males (30.8) was similar to N. gonorrhoeae (P = 0.78) but less than T. vaginalis (mean, 41.6; P < 0.0001). A total of 266 STI clinic encounters had at least 1 sexually transmitted infection (STI); 36.5% of these encounters had sole detection of M. genitalium (P ≤ 0.009 versus sole detection of other STI agents). In 209 community encounters with at least 1 STI, 22.0% exhibited sole detection of M. genitalium (P = 0.0007 versus sole M. genitalium detection in STI clinic males), while 18.7% had sole detection of T. vaginalis (P < 0.0002 versus detection in STI clinic males). TMA-based M. genitalium screening identifies additional cases of nongonococcal urethritis., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background: Chlamydia trachomatis is mentioned among the etiologic factors for urinary tract infections. Chlamydias are parasites inside a cell. A very significant problem of C. trachomatis infections is their asymptomatic character. The most frequent infections caused by these bacteria are inflammations of the urethra and bladder; of the vagina, cervix, vaginal cavity and adnexa in women; and of the epididymis, testicles and prostate in men. In the diagnosis of C. trachomatis infections, the following methods are used: immunofluorescent techniques, immunoenzymatic assays, serological examinations and genetic techniques (for example PCR)., Objectives: The aim of the study was to detect C. trachomatis among patients with symptoms of non-gonorrheal urethritis using diagnostic serologic methods and direct immunofluorescence. The purpose was to assess the connection between the incidence of urinary tract infections caused by C. trachomatis and symptoms that patients report as well as other data from interviews., Material and Methods: Blood serum and urethral smears were taken from each of 57 patients. The ELISA method was used to mark specific IgG and IgGcHSP60 anti-chlamydia antibodies in the blood serum. In the urethral smear, antigens were marked using the direct immunofluorescence method., Results: Evidence for urinary tract infection caused by C. trachomatis was found in 15.79% of the examined patients using the immunofluorescence method. In the blood serum, positive results for IgGcHSP60 were obtained in 17.54% of the patients and for IgG in 8.77%., Conclusions: The studies carried out so far suggest that C. trachomatis has a significant role in the etiology of urethritis in adults and children. Other serological tests should be conducted in all the patients in order to study the immune responses in infected individuals and to confirm C. trachomatis infection using genetic methods such as PCR.

We conducted a study to determine the prevalence of Trichomonas vaginalis (TV), Mycoplasma genitalium (MG) and Ureaplasma urealyticum (UU) in men with urethritis, attending an urban sexual health clinic, in order to inform screening and treatment policies. Men attending an urban sexual health clinic between June 2011 and January 2012 were evaluated. Urine samples were collected from men with urethritis and tested for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC) and TV using transcription-mediated amplification and for MG and UU using polymerase chain reaction. Eighty-three samples were analysed. The prevalence of CT was 33.7% (28/83), GC was 16.8% (14/83), TV was 3.6% (3/83), MG was 12.0% (10/83) and UU was 4.8% (4/83). Fifteen men had recurrent urethritis. Of these, three were found to have had TV, five to have had MG and none to have had UU, at initial presentation. Given the prevalence of MG in this study, there is an urgent need for further larger studies looking at optimal treatment regimens and screening strategies in urethritis., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Background: Azithromycin has been widely used for Mycoplasma genitalium treatment internationally. However, the eradication efficacy has substantially declined recent decade. In Russia, josamycin (another macrolide) is the recommended first-line treatment for M. genitalium infections, however, no data regarding treatment efficacy with josamycin and resistance in M. genitalium infections have been internationally published. We examined the M. genitalium prevalence in males attending an STI clinic in Moscow, Russia from December 2006 to January 2008, investigated treatment efficacy with josamycin in male urethritis, and monitored the M. genitalium DNA eradication dynamics and selection of macrolide resistance in M. genitalium during this treatment., Methods: Microscopy and real-time PCRs were used to diagnose urethritis and non-viral STIs, respectively, in males (n = 320). M. genitalium positive patients were treated with recommended josamycin regimen and treatment efficacy was monitored using quantitative real-time PCR. Macrolide resistance mutations were identified using sequencing of the 23S rRNA gene., Results: Forty-seven (14.7%) males were positive for M. genitalium only and most (85.1%) of these had symptoms and signs of urethritis. Forty-six (97.9%) males agreed to participate in the treatment efficacy monitoring. All the pre-treatment M. genitalium specimens had wild-type 23S rRNA. The elimination of M. genitalium DNA was substantially faster in patients with lower pre-treatment M. genitalium load, and the total eradication rate was 43/46 (93.5%). Of the six patients with high pre-treatment M. genitalium load, three (50%) remained positive post-treatment and these positive specimens contained macrolide resistance mutations in the 23S rRNA gene, i.e., A2059G (n = 2) and A2062G (n = 1)., Conclusions: M. genitalium was a frequent cause of male urethritis in Moscow, Russia. The pre-treatment M. genitalium load might be an effective predictor of eradication efficacy with macrolides (and possibly additional antimicrobials) and selection of macrolide resistance. Additional in vivo and in vitro data are crucial to support the recommendation of using josamycin as first-line treatment for M. genitalium infections in Russia. It would be valuable to develop international M. genitalium management guidelines, and quantitative diagnostic PCRs determining also M. genitalium load and resistance mutations (for macrolides and ideally also moxifloxacin) should ideally be recommended.

Background: Nongonococcal urethritis (NGU) is the most common male reproductive tract syndrome. Ureaplasmas spp. including U. urealyticum and U. parvum, have been increasingly reported to be implicated in NGU. However, there are still many contradictions about their pathogenic role in NGU., Aims: The goals of this study were to evaluate the association of Ureaplasmas spp. with NGU, and to compare the prevalence of Ureaplasmas spp. infection in China relative to the world average., Methods: A systematic review and meta-analysis was conducted following standard guidelines for meta-analysis. The quality of included studies was assessed by Newcastle-Ottawa scale., Results: A total of seven studies involving 1,507 NGU patients and 1,223 controls were eligible for meta-analysis. There was no significant difference in the Ureaplasma spp. positive rate between the NGU and control groups. However, the U. urealyticum positive rate was significantly higher in NGU patients compared to controls; the U. parvum positive rate was significantly higher in controls compared to NGU patients. Furthermore, within the NGU patient group, the positive rate of U. urealyticum was significantly higher than that of U. parvum, whereas within the control group, the opposite trend was observed. Compared to the world average, a significantly higher positive rate of Ureaplasma spp. was observed in both the NGU and control groups in China., Conclusions: Our analysis supports that U. urealyticum, but not U. parvum, is an etiological agent in NGU. More detailed studies of these two species in China and the world could contribute to a better understanding of the epidemiology and pathogenesis, and facilitate the development of better strategies for treatment and prevention of NGU.

Background: Periodic etiological surveillance of sexually transmitted infection (STI) syndromes is required to validate treatment algorithms used to control STIs. However, such surveys have not been performed in Zimbabwe over the past decade., Methods: A cross-sectional study design was used to determine the prevalence of the key STI etiological agents causing male urethral discharge (MUD). Urethral swab specimens were collected for molecular analysis and Neisseria gonorrhoeae isolation from consenting men 18 years and older who presented with MUD to the 12 clinics in Harare, Zimbabwe, between November 2010 and May 2011. A validated in-house multiplex polymerase chain reaction assay was used to detect the presence of N. gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, and Mycoplasma genitalium. Gonococci were cultured on selective media, and antimicrobial susceptibilities were determined locally for ciprofloxacin, kanamycin, ceftriaxone, and cefixime using Etest strips, and minimum inhibitory concentrations were reported using defined breakpoints., Results: Among 130 participants, N. gonorrhoeae was the most frequent pathogen detected (106; 82.8%), followed by C. trachomatis (15; 11.7%), M. genitalium (6; 4.7%), and T. vaginalis (2; 1.6%). Four (6.1%) of the 66 gonococci isolated were resistant to fluoroquinolones, whereas all viable isolates were susceptible to kanamycin, cefixime, and ceftriaxone., Conclusions: Gonorrhea is the most important cause of MUD in men in Harare, and our study highlights the emergence of fluoroquinolone-resistant N. gonorrhoeae. Further STI surveys are required in other regions of Zimbabwe to obtain a nationally representative picture of gonococcal burden and antimicrobial resistance among MUD patients.

Introduction: Urethral discharge is a common presentation of sexually transmitted infection (STI) in men and known pathogens include Neisseria gonorrhoeae and Chlamydia trachomatis. There are no published data of the burden of urethral discharge among men in Fiji., Objective: To evaluate urethral discharge among men to determine the incidence, the frequency of recurrence and reported at-risk behaviour., Methods: We conducted a retrospective, descriptive study of clinical records of all men presenting with urethral discharge to two major reproductive health clinics. Data collected included self-reported at-risk behaviours, results of abnormal syphilis serology and antibiotics prescribed. The frequency of recurrence in the following 1-2 years of initial presentation was determined along with microbiological findings from urethral swab in this group., Results: A total of 748 males presented with urethral discharge to the clinic in one year. This represents an incidence rate of at least 295 per 100,000 adult males per year in the study population. Within the next 1-2 years of the initial presentation, 102 (14%) of these re-presented out of which 42 had urethral swab taken for etiological diagnosis. The commonest isolate was Neisseria gonorrhoeae. Results of syphilis tests were available for 560 (75%) of patients and 29 (5%) were positive. Recurrence was not associated with self-reported at-risk behaviours., Conclusion: The incidence of urethral discharge among males in Fiji is very high and prevention strategies are urgently needed.

Nongonococcal urethritis (NGU) is a common clinical syndrome, but no etiological agent is identified in a significant proportion of cases. Whether the spectrum of pathogens differs between heterosexual men (MSW) and men who have sex with men (MSM) is largely unstudied but of considerable clinical relevance. A retrospective review was done using the electronic medical record database of Melbourne Sexual Health Centre, Australia. Cases were first presentations of symptomatic acute NGU with ≥ 5 polymorphonuclear leukocytes (PMNL)/high-powered field (HPF) on urethral Gram stain between January 2006 and December 2011. First-stream urine was tested for Chlamydia trachomatis and Mycoplasma genitalium by PCR. Demographic, laboratory, and behavioral characteristics of cases were examined by univariate and multivariable analyses. Of 1,295 first presentations of acute NGU, 401 (32%; 95% confidence interval [CI] of 29 to 34%) had C. trachomatis and 134 (11%; 95% CI of 9 to 13%) had M. genitalium detected. MSM with acute NGU were less likely to have C. trachomatis (adjusted odds ratio [AOR] = 0.4; 95% CI of 0.3 to 0.6) or M. genitalium (AOR = 0.5; 95% CI of 0.3 to 0.8) and more likely to have idiopathic NGU (AOR = 2.4; 95% CI of 1.8 to 3.3), to report 100% condom use for anal/vaginal sex (AOR = 3.6; 95% CI of 2.7 to 5.0), or to have engaged in sexual activities other than anal/vaginal sex (AOR = 8.0; 95% CI of 3.6 to 17.8). Even when C. trachomatis or M. genitalium was detected, MSM were more likely than MSW to report consistent condom use (OR = 4.7; 95% CI of 2.6 to 8.3). MSM with acute NGU are less likely to have the established bacterial sexually transmitted infections (STIs) and more likely to report protected anal sex or sexual activity other than anal sex prior to symptom onset than MSW. These data suggest that the etiologic spectrum of pathogens differs between MSM and MSW in acute NGU and that relatively low-risk practices are capable of inducing acute NGU., (Copyright © 2014, American Society for Microbiology.
