An audit of all cases of chlamydial infection diagnosed in men at the Edinburgh genitourinary (GU) medicine clinic over a six-month period from January 2003 is reported. In all, 189 men identified as requiring treatment for possible chlamydial infection on first attendance (because of contact with a partner with chlamydia or the diagnosis of non-gonococcal urethritis [NGU] on microscopy), who later proved chlamydia-positive by polymerase chain reaction (PCR), were compared with 83 men in whom infection was identified only on receipt of a PCR result. Treatment rates were 100% in the first group and 97.6% in the second group (χ2 0.046, P <0.05). In men presumptively diagnosed and treated, 88.6% of contacts identified were confirmed as traced, compared with 90% confirmed as traced in the group diagnosed by PCR alone. Our audit suggests that identifying men with chlamydial NGU by routine microscopy may carry a small but significant advantage in increasing treatment rates, but makes no difference to contact-tracing success rate.

AbstractDevelopment of rapid, reliable, and easy diagnostic tests with high-throughput is the need of the hour for laboratories combating the COVID-19 pandemic. While real-time polymerase chain reaction (RT-PCR) is the gold standard for diagnosing active infections, it is expensive and time-consuming. Serological diagnostic assays with a premise to aid rapid contact tracing, immune status determination, and identification of potential convalescent plasma donors hold great promise. Timely diagnosis, effective treatment, and future prevention are key to management of COVID-19.

A significant association of Mycoplasma genitalium with non-gonococcal urethritis has been reported, but the prevalence of this mycoplasma in men with gonococcal urethritis has not been so well studied. In this study, we examined urethral swab specimens from 45 Japanese male patients with gonococcal urethritis for the presence of M. genitalium by using a polymerase chain reaction-based assay. We also sought Chlamydia trachomatis by an enzyme immunoassay Chlamydiazyme . Of the 45 specimens, 2 4.4 were positive for the mycoplasma and 12 26.7 were positive for C. trachomatis. The findings suggest that M. genitalium may be a cause not only of non-gonococcal urethritis but also of postgonococcal urethritis.

Background: Role of adenoviruses in non-gonococcal urethritis (NGU) has been reported in only a few studies. The aim of the study was to detect and type adenoviruses in men presenting with NGU. Methods: 636 heterosexual and homosexual men presenting with NGU from Melbourne, Australia were recently evaluated for various aetiological organisms including adenovirus. We utilised methods including polymerase chain reaction for detection followed by sequence analysis to type positive samples. Results: Overall, 12 samples from patients with NGU had adenovirus detected. Five types were identified: type 4 (subgenus E), type 35 (subgenus B), and types 9, 37 and 49 (subgenus D). The presence of mixed adenovirus strains was not detected in any sample. Conclusion: Overall, subgenus B, D and E were predominant in this patient population.

Objective: To study the clinical features and the state of general immunological reactivity in non-gonococcal urethritis (NGU) in men. Methods: Examined 100 men between the ages of 20 and 48 years: 75 patients of NGU (main group) and 25 healthy (control group). The average age of the patients was 26.7±1.7 years, and the male of control group was 27.9±1.7 years. Clinical, microscopic, immunological research methods were used, including direct immunofluorescence (DIF), polymerase chain reaction (PCR). Results: Ureaplasma urealyticum was found in 37 (49.3%) patients, 33 (44%) had Chlamydia trachomatis, 23 (30.7%) had Mycoplasma genitalium, 16 (21.3%) had Trichomonas vaginalis. In 24 (32%) of NGU patients had a mixed infection: in 14 (18.7%) had a combination of two STIs and in 10 (13, 3%) had three infections. In 51 (68%) of patients the process passed in the form of monoinfection. Various complaints (dysuric disorders, pain, discomfort and agglutination of the labium urethra) were presented by 51 (68%) of sick patients. The excretions from the urethra were marked in 46 (61.3%) of patients, reproductive disorders are 3 times less common. Immunological disorders were manifested by a decrease in CD4 and CD8 lymphocytes, PHA, PN and IL-10, increase – IgM, IgG, CIC, TNFα, IL-1β. Conclusions: The most common cause of NGU is Ureaplasma urealyticum and Chlamydia trachomatis. In most cases NGU proceeds in the form of monoinfection. Subjective and objective symptoms occur in 64% and 59% of patients, respectively. Immunological disorders were detected in 71% of patients.
