Non-gonococcal urethritis

Chlamydia Infection from Androgical Perspective

Chlamydia trachomatis is a microorganism known for years to cause ocular, urogenital, and neonatal infections in humans. It usually causes urogenital system infections. The pathogen, which is the most common cause of urethritis in males, is one of the sexually transmitted microorganisms. As most males are asymptomatic, they do not realize they are infected and act as reservoirs. This causes the incidence of urethritis due to chlamydia to increase day by day. Chlamydia urethritis, which poses a risk to sexual partners, can cause serious complications if left untreated. In this section, we assess the approach to male urethritis due to chlamydia, which is very common in urology practice and can cause serious problems if left untreated.

Sexuality Transmitted Infection in the COVID-19 Pandemic and Non-Pandemic Time

On March 11, 2020, the World Health Organization recognized the SARS-CoV-2 infection as a pandemic. The pandemic itself in addition to its containment measures affects individuals' lifestyles and welfare including their sexual behaviors. Thus, we hypothesized that sexually transmitted infection (STI) incidence may be changed and so we evaluate urethritis incidence as the most common STI in men and some other related factors. Two cross-sectional surveys during the first 6 months of 2019 and 2020 were undertaken and data were collected from 11 urology offices located in different parts of the capital city. In total, 34,611 male participants were included in our study, and 191 (.55%) patients' clinical diagnoses were urethritis. The urethritis incidence significantly decreased from 149 of 17,950 (.83%) to 42 of 16,661 (.25%) individuals in the same period of the years 2019 and 2020, respectively (p-value < .001). There was a higher percentage of single (p-value = .049) and older (p-value < .001) urethritis patients in the first 6 months of the year 2020 compared with 2019. Our survey provided urethritis incidence, demographics, symptoms, and treatment characterization. As our results show, the proportion of urethritis patients in all populations admitted to urologist offices had dramatically decreased during the COVID-19 pandemic compared with prior. The indirect effects of the pandemic and its containment measures on people's sexual health should be noticed and an appropriate reaction and policy-making are recommended to manage issues properly in different aspects of sexual health.

Profile of sexually transmitted infections causing urethritis and a related inflammatory reaction in urine among heterosexual males: A flow-cytometry study

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.

Accuracy of Presumptive Gonorrhea Treatment for Gay, Bisexual, and Other Men Who Have Sex with Men: Results from a Large Sexual Health Clinic in Los Angeles, California

PURPOSE

This study analyzed the accuracy of presumptive gonorrhea treatment in a sexual health clinic serving primarily gay, bisexual, and other men who have sex with men (MSM). Treating suspected gonorrhea before laboratory confirmation can reduce symptoms and transmission; however, this strategy can overtreat uninfected individuals, which may promote antimicrobial resistance. We identified differences in accuracy of gonorrhea presumptive treatment by site of infection and presence of signs or symptoms.

METHODS

We conducted a cross-sectional study of gay, bisexual, and other MSM who were treated presumptively for gonorrhea at the Los Angeles LGBT Center between February and July 2015. We calculated positivity of treated patients, proportion of infections treated, and positive predictive value (PPV) of treating gonorrhea presumptively based on signs, symptoms, or exposure at the urethral, rectal, or pharyngeal site.

RESULTS

Of 9141 testing visits, presumptive treatment was provided at 1677 (18%). Overall, gonococcal infections were identified at 31% (n = 527) of visits where presumptive treatment was provided, compared to 9% (n = 657) of visits without presumptive treatment (P < 0.01). Forty-five percent of gonococcal infections were treated presumptively, and treatment was provided at 14% of gonorrhea-negative visits. Seventy-eight percent of urethral, 54% of rectal, and 35% of pharyngeal infections were treated presumptively. PPV was highest for genitourinary signs.

CONCLUSION

Approximately one-third of gay, bisexual, or other MSM treated presumptively for gonorrhea at a sexual health clinic tested positive for gonorrhea. These findings highlight the potential contribution of point-of-care tests in reducing overtreatment resulting from presumptive treatment.
