RESUMO

BACKGROUND: Information about the use of flow cytometry in the diagnosis of male urethritis is scarce. The current study aims to evaluate the performance of flow cytometry on first-voided urine in males with infectious urethritis (Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis). METHODS: Male patients of the Andrology Centre (Tartu University Hospital, Estonia) were recruited during the period March 2015 -January 2018. Cases included 306 patients with infectious urethritis caused by Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and/or Trichomonas vaginalis. The control group consisted of 192 patients without uro-genital complaints, negative tests for C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis from first-voided urine and no inflammation in first-voided urine, mid-stream urine and urine after prostate massage. C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis were detected from first-voided urine using polymerase chain reaction (PCR) method. First-voided urine was analysed using urine particle analyzer Sysmex UF-500i. RESULTS: The most prevalent infection was chlamydia (64.1%), followed by Mycoplasma genitalium (20.9%), gonorrhoea (7.8%) and trichomoniasis (1.6%). Gonorrhoea caused the highest flow-cytometric leucocyte/bacteria count, followed by chlamydia and Mycoplasma genitalium. Trichomonas vaginalis showed nearly absent inflammation in first-voided urine. Using an empiric flow-cytometry diagnostic threshold for urethritis in first-voided urine (leucocytes ≥ 15/µl and bacteria ≥ 20/µl) the total calculated sensitivity was over 90%. However, when applying such criteria for deciding whether to perform first-voided urine PCR for C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis or not, we could miss 23 cases with infectious urethritis that makes up 7,5% of all proven cases. CONCLUSIONS: Flow cytometry of first-voided urine can be considered as a rapid and objective screening method in case of suspected male infectious urethritis.

RESUMO

PURPOSE: Histopathology can provide insights into disease mechanisms but to date it has been poorly described for urethral stricture. The purpose of this study was to comprehensively describe histopathological findings of stricture specimens obtained at the time of anterior urethroplasty. MATERIALS AND METHODS: All pathological specimens of men who underwent anterior urethroplasty of urethral stricture disease from 2010 to 2017 at a single institution were rereviewed by a single blinded pathologist directed to rule out lichen sclerosus and then describe inflammatory cell type and severity when present. Cohorts comprising strictures with no inflammation, minimal to mild inflammation or moderate to severe inflammation were developed and stricture, patient and surgical outcome characteristics were compared. RESULTS: Histopathology slides from 100 anterior urethroplasty cases were reviewed. Two or more lichen sclerosus characteristics were present in 21% of specimens and 44% of specimens showed chronic inflammation, which was minimal in 20%, mild in 39%, moderate in 39% and severe in 2%. Lymphocytes in 86% of specimens and plasma cells in 12% were the predominant cell types. Patients with inflammatory stricture reported worse overall health. Inflammation was largely absent from isolated bulbomembranous strictures (9%) and more common in lichen sclerosus strictures (100%). The 11% overall failure rate was not affected by the presence (7%) or absence (14%) of inflammation. CONCLUSIONS: Chronic inflammation is prevalent in a significant percent of urethral stricture disease specimens. Associations with worse overall health suggest systemic mediators. Absent inflammation in bulbomembranous strictures suggests a unique pathophysiology in this region. The presence of inflammation did not affect surgical outcomes at mid-term followup.

RESUMO

OBJECTIVE: To assess the cost-effectiveness of three testing strategies with or without light microscopic Gram-stained smear (GSS) evaluation for the detection of anogenital gonorrhoea among men who have sex with men (MSM) at the Amsterdam STI clinic using a healthcare payer perspective. METHODS: Three testing strategies for MSM were compared: (1) GSS in symptomatic MSM only (currently practised strategy), (2) no GSS and (3) GSS in symptomatic and asymptomatic MSM. The three testing protocols include testing with nucleic acid amplification test to verify the GSS results in (1) and (3), or as the only test in (2). A transmission model was employed to calculate the influence of the testing strategies on the prevalence of anogenital gonorrhoea over 10 years. An economic model combined cost data on medical consultations, tests and treatment and utility data to estimate the number of epididymitis cases and quality-adjusted life years (QALY) associated with gonorrhoea. Incremental cost-effectiveness ratios (ICERs) for the testing scenarios were estimated. Uncertainty and sensitivity analyses were performed. RESULTS: No GSS testing compared with GSS in symptomatic MSM only (current strategy) resulted in nine extra epididymitis cases (95% uncertainty interval (UI): 2-22), 72 QALYs lost (95% UI: 59-187) and €7300 additional costs (95% UI: -€185 000 (i.e.cost-saving) to €407 000) over 10 years. GSS testing in both symptomatic and asymptomatic MSM compared with GSS in symptomatic MSM only resulted in one prevented epididymitis case (95% UI: 0-2), 1.1 QALY gained (95% UI: 0.1-3.3), €148 000 additional costs (95% UI: €86 000 to-€217 000) and an ICER of €177 000 (95% UI: €67 000-to €705 000) per QALY gained over 10 years. The results were robust in sensitivity analyses. CONCLUSIONS: GSS for symptomatic MSM only is cost-effective compared with no GSS for MSM and with GSS for both symptomatic and asymptomatic MSM.

RESUMO

We documented urethral Treponema pallidum infection in a man with nongonococcal urethritis and a negative syphilis serology using broad-range bacterial polymerase chain reaction (PCR) and sequencing, targeted PCR, and immunofluorescence microscopy. He subsequently seroconverted for syphilis. Early syphilis may present as urethritis. Urethral T. pallidum shedding can occur before seroconversion.

RESUMO

BACKGROUND: Proliferative urethritis (PU) is a lower urinary tract disease of dogs characterized by frond-like lesions in the urethra. The etiology of PU is unknown, although an association with bacterial cystitis is reported. OBJECTIVES: Deep-seated bacterial cystitis is associated with PU, particularly in dogs with neutrophilic or granulomatous inflammation. ANIMALS: Twenty-two client-owned dogs with PU and 5 control dogs euthanized for non-urinary disease. METHODS: In retrospective analysis, medical records of dogs with PU from 1986 to 2016 were reviewed. Signalment, clinical signs, cystoscopic findings, antimicrobial use, and results of urine, bladder, or urethral tissue cultures, if available, were recorded. Histopathology was reviewed and classified as lymphocytic-plasmacytic (LP), neutrophilic, LP-neutrophilic (LPN), granulomatous, or pleocellular. Eubacterial fluorescence in situ hybridization (FISH) was performed on 18 tissue samples (13 cases, 5 controls), with subsequent evaluation of bacterial species. RESULTS: Of the 22 dogs, 9 had LP urethritis, 6 had LPN, 4 had pleocellular, and 3 had neutrophilic urethritis. Of note, 7 of 13 PU samples were FISH+ for adherent or invasive bacteria; 1 of 5 controls were FISH+ for adherent bacteria. Five dogs had negative urine and tissue cultures when FISH was positive. There was no association detected between the type of urethral inflammation and the results of urine and tissue culture or FISH. CONCLUSIONS AND CLINICAL IMPORTANCE: The type of inflammation varied widely in these 22 PU cases. Deep-seated bacterial urethritis could be contributing to the inflammatory process in some dogs, regardless of the inflammation type. Urine and tissue cultures likely underestimate bacterial colonization of the urethra in dogs.

RESUMO

BACKGROUND: Idiopathic bulbar urethritis (IBU) is characterized by hematuria ± dysuria without infection. Symptoms result from inflammation of the bulbar urethra, distal to external sphincter. IBU is difficult to manage and there is no recommended therapy. OBJECTIVE: To determine whether instillation of triamcinolone acetonide is a useful treatment of IBU and its associated complications. SETTING AND PARTICIPANTS: Data were prospectively collected, for 22 months, on 14 consecutive patients presenting with terminal hematuria or blood spotting ± dysuria to a pediatric urology unit. Median age was 12 years (range: 10-15). Mean symptom duration was 13 months (range: 8-24). Normal baseline laboratory blood tests, urine cultures, and ultrasound assessments were seen in all; therefore, none were excluded on the basis of a known pathology. Follow-up telephone interviews, to assess symptom persistence and side effects, were performed at 6 weeks postintervention. The mean follow-up period was 15 months (range: 4-20). INTERVENTION: Visual confirmation of IBU was obtained cystoscopically and 40 mg of triamcinolone was instilled to the inflamed area under direct vision using an open-ended ureteral catheter. OUTCOME MEASUREMENTS: Symptoms resolution was the primary outcome. Repeat cystoscopic assessment ± triamcinolone instillation was recorded, as was the occurrence of complications. RESULTS AND LIMITATIONS: Seven patients (50%) required at least one further treatment. Overall complete or partial resolution was reported in 12/14 patients (85.7%). No side effects were reported. CONCLUSIONS: This small prospective series demonstrates that intraurethral instillation of triamcinolone seems to be a promising treatment option to alleviate inflammatory symptoms in majority of cases of idiopathic urethritis. Patient Summary: Fourteen boys with inflammation of the urethra, with no identifiable cause, were treated by topically triamcinolone, directly to the inflamed area. We demonstrate an 85.7% complete/partial resolution of symptoms with no side effects seen.

RESUMO

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.

RESUMO

Recent assessments have examined the composition of bacterial communities influencing reproductive, pregnancy and infant health. The Microbiome Project has made great strides in sequencing the microbiome and identifying the vast communities of microorganisms that inhabit our bodies and much work continues to examine the individual contribution of bacteria on health and disease to inform future therapies. This review explores the current literature outlining the contribution of important bacteria on reproductive health among sexually active men and women, outlines gaps in current research to determine causal and interventional relationships, and suggests future research initiatives. Novel treatments options to reduce adverse outcomes must recognize the heterogeneity of the bacteria within the microbiome and adequately assess long-term benefits in reducing disease burden and re-establishing a healthy Lactobacillus-dominant state. Recognizing other reservoirs outside of the lower genital track and within sexual partners as well as genetic and individual moderators may be most important for long-term cure and reduction of disease. It will be important to develop useful screening tools and comprehensively examine novel therapeutic options to promote the long-term reduction of high-risk bacteria and the re-establishment of healthy bacterial levels to considerably improve outcomes among pregnant women and sexually active men and women.

RESUMO

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.

RESUMO

Short-chain fatty acids (SCFAs) are major products of gut microbial fermentation and profoundly affect host health and disease. SCFAs generate IL-10(+) regulatory T cells, which may promote immune tolerance. However, SCFAs can also induce Th1 and Th17 cells upon immunological challenges and, therefore, also have the potential to induce inflammatory responses. Because of the seemingly paradoxical SCFA activities in regulating T cells, we investigated, in depth, the impact of elevated SCFA levels on T cells and tissue inflammation in mice. Orally administered SCFAs induced effector (Th1 and Th17) and regulatory T cells in ureter and kidney tissues, and they induced T cell-mediated ureteritis, leading to kidney hydronephrosis (hereafter called acetate-induced renal disease, or C2RD). Kidney hydronephrosis in C2RD was caused by ureteral obstruction, which was, in turn, induced by SCFA-induced inflammation in the ureteropelvic junction and proximal ureter. Oral administration of all major SCFAs, such as acetate, propionate, and butyrate, induced the disease. We found that C2RD development is dependent on mammalian target of rapamycin activation, T cell-derived inflammatory cytokines such as IFN-γ and IL-17, and gut microbiota. Young or male animals were more susceptible than old or female animals, respectively. However, SCFA receptor (GPR41 or GPR43) deficiency did not affect C2RD development. Thus, SCFAs, when systemically administered at levels higher than physiological levels, cause dysregulated T cell responses and tissue inflammation in the renal system. The results provide insights into the immunological and pathological effects of chronically elevated SCFAs.

RESUMO

We present eight cases and review the literature of concurrent urethritis and conjunctivitis where adenovirus was identified as the causative pathogen. The focus of this review concerns the identification of specific sexual practices, symptoms, signs and any serotypes that seem more commonly associated with such adenovirus infections. We discuss the seasonality of adenovirus infection and provide practical advice for clinicians to give to the patient.

RESUMO

Haemophilus parainfluenzae is a common inhabitant of the human upper respiratory tract of the normal oral microflora. We report three men who had been having unprotected sex with men (MSM) and subsequently acquired H. parainfluenzae urethritis, which was confirmed by 16S rRNA gene sequencing analysis. Two men were treated with ceftriaxone and doxycycline, and the third man was treated with clarithromycin. All three patients responded to treatment. This case series highlights the potential role of H. parainfluenzae as a sexually transmitted genitourinary pathogen.

RESUMO

Urethral polyp is one of differential diagnoses for the male patients complain of gross-hematuria and/or hematospermia. However, there have been limited numbers of case reports including infectious etiology. Here we reported clinical course and pathological findings of one rare case who was diagnosed and treated as urethral polyp-like lesions on the prostatic urethra caused by Chlamydia trachomatis infection. A 25 year-old man who had a past history of frequent sexual intercourse with unspecified female sexual partner visited the clinic. His chief complaint was gross-hematuria and hematospermia. Endoscopic findings showed that non-specific hemorrhagic polyp-like lesions. To determine the pathological findings including malignant diseases and diagnosis, transurethral resection was performed. Because the pathological findings were similar to those of chlamydial proctitis, additional examination was done. As the results, nucleic acid amplification test of C. trachomatis in urine specimen was positive and immunohistochemical staining of specific chlamydia antigen in resected specimen was also positive. Treatment by orally minocyline 100 mg twice daily for 4 weeks was introduced. After the treatment, symptom was disappeared and nucleic acid amplification test of C. trachomatis in urine specimen turned to be negative. No recurrence was reported 2 years posttreatment.

RESUMO

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.

RESUMO

This study was performed to determine the associations between human papillomavirus (HPV) infection and cytological changes in the male glans and urethral samples. Two rubbed samples of the glans and distal urethra were collected from 160 patients with urethritis, and the collected cells were placed into preservative solution for liquid-based cytology. DNA was extracted from all samples, and ß-globin gene amplification, HPV-DNA test, and HPV genotyping were performed. After papanicolaou staining of each sample, cytological findings were assessed based on nine non-classic signs, and compared with the results of HPV-DNA test. Among the ß-globin positive samples, HPV (any type) was detected in 33 and 25% of the glans and urethra samples, respectively. High-risk HPV-DNA was detected in 25 and 15% of the glans and urethra samples, respectively. In the glans samples, cytological signs of HPV infection were observed in 17% of low-risk HPV-positive samples and in 58% of high-risk HPV-positive samples. Cytological atypia suspected to indicate penile intraepithelial neoplasia were observed in 17 and 33%, respectively. On the other hand, abnormal cells were observed in 29% of low-risk HPV-positive and 83% of high-risk HPV-positive urethral samples. Cytological atypia suspected to be urethral intraepithelial neoplasia was observed in 29 and 65%, respectively. In situ hybridization demonstrated the presence of HPV-DNA in the morphologically abnormal cells in 31 and 35% of high-risk HPV-positive glans and urethral samples, respectively. Cytological changes similar to cervical intraepithelial neoplasia in females could be detected in the HPV-positive glans and urethral samples.

RESUMO

PURPOSE: To review the clinical outcome of I-125 permanent prostate brachytherapy (PPB) for low-risk and intermediate-risk prostate cancer and to compare 2 techniques of loose-seed implantation. METHODS AND MATERIALS: 574 consecutive patients underwent I-125 PPB for low-risk and intermediate-risk prostate cancer between 2000 and 2008. Two successive techniques were used: conventional implantation from 2000 to 2004 and automated implantation (Nucletron, FIRST system) from 2004 to 2008. Dosimetric and biochemical recurrence-free (bNED) survival results were reported and compared for the 2 techniques. Univariate and multivariate analysis researched independent predictors for bNED survival. RESULTS: 419 (73%) and 155 (27%) patients with low-risk and intermediate-risk disease, respectively, were treated (median follow-up time, 69.3 months). The 60-month bNED survival rates were 95.2% and 85.7%, respectively, for patients with low-risk and intermediate-risk disease (P=.04). In univariate analysis, patients treated with automated implantation had worse bNED survival rates than did those treated with conventional implantation (P<.0001). By day 30, patients treated with automated implantation showed lower values of dose delivered to 90% of prostate volume (D90) and volume of prostate receiving 100% of prescribed dose (V100). In multivariate analysis, implantation technique, Gleason score, and V100 on day 30 were independent predictors of recurrence-free status. Grade 3 urethritis and urinary incontinence were observed in 2.6% and 1.6% of the cohort, respectively, with no significant differences between the 2 techniques. No grade 3 proctitis was observed. CONCLUSION: Satisfactory 60-month bNED survival rates (93.1%) and acceptable toxicity (grade 3 urethritis<3%) were achieved by loose-seed implantation. Automated implantation was associated with worse dosimetric and bNED survival outcomes.

RESUMO

Specimens from men with acute non-gonococcal urethritis were tested to determine their microbial content and then given intra-urethrally to male chimpanzees. Two animals received ureaplasmas only and one became infected. The second did so when given a different strain. Both developed a polymorphonuclear leukocyte (PMNL) response. Two chimpanzees received a mixture of ureaplasmas and Chlamydia trachomatis and there was a suggestion that the ureaplasmas delayed or suppressed the chlamydial response. The latter, that is urethral infection with a pronounced PMNL response, was most clearly seen in a chimpanzee given C. trachomatis only. No inflammation was detected in two chimpanzees acting as controls. Three of five chimpanzees given ureaplasmas genitally, and one that had them endogenously, had them transiently in the oropharynx about 2 weeks later. The occurrence of ureaplasmas in the conjunctiva of three chimpanzees inoculated at this site was also transient and without inflammation. The possibility that Mycoplasma genitalium might have been in the inocula and caused urethral inflammation was discounted largely because no animal had antibody to this mycoplasma.

RESUMO

Trichomonas vaginalis is the most common curable sexually transmitted infection worldwide. T vaginalis infections in women can range from asymptomatic to acute inflammatory vaginitis. In men, this infection is typically asymptomatic but is increasingly being recognised as a cause of non-gonococcal urethritis. Diagnosis of T vaginalis has traditionally been made by direct microscopic examination of a wet mount of vaginal fluid or through the use of culture. The recent commercial availability of nucleic acid amplification tests for the detection of T vaginalis has seen these replace culture as the gold standard for diagnosis. Nitroimidazoles (ie, metronidazole and tinidazole) are the mainstay of therapy. In the case of treatment failure due to drug resistance or in the case of a severe nitroimidazole allergy, alternative intravaginal therapies exist, although their effectiveness has not been evaluated systematically. Novel systemic agents other than nitroimidazoles for the treatment of T vaginalis are needed, and efforts to promote and support antimicrobial drug development in this setting are necessary.

RESUMO

In our study 54 patients were diagnosed epididymitis caused by STI and in 6 (11.1%) cases inflammatory process spread on seminal vesicles which negatively affected the state of male reproductive function. After having unilateral epididymitis pathospermia developed in 76% of cases and infertility - in 55.6%. In patients who had unilateral acute epididymitis, infertility caused by urethritis of chlamidial aetiology developed in 70.4% of cases, infertility caused by urethritis of mycoplasmatic (ureaplasma) genesis - in 62.9% of cases and infertility caused by gonorrheal urethritis - in 29.6% of cases. At this moment following alterations of ejaculate are revealed: volume reduction, decrease in spermatozoid number, reduction of ability to move, increase in teratomatous forms, spermagglutination, etc. The best way for prevention of pathospermia and infertility is using modern and adequate treatment methods directed to maximally effective suppression of acute inflammatory process in epididymis and then restoration of its functions.
