335 Predictors of Gonorrhea and Chlamydia in Emergency Department Patients

Prevalence of Chlamydia trachomatis and Listeria monocytogenes in Infertile Men and the Effect on Semen Parameters

Background: Infertility is one of the serious problems in gynecology and one of the most important issues of concern in couples. Meanwhile, a significant rise in infertility is recently reported in Iran due to the infections and harsh environmental conditions. Objectives: The current study aimed to detect Chlamydia trachomatis and Listeria monocytogenes in males with infertility using PCR, and to evaluate bacteriospermia effects of the studied bacteria on semen parameters. Methods: Semen specimens of 100 infertile men were collected. Then, each specimen was divided into two parts: the first part was tested by semen analysis according to the WHO guidelines and the second was tested using the PCR method. The PCR intended to identify C. trachomatis and L. monocytogenes. Results: Out of 100 semen samples, 20% were positive for C. trachomatis, 3% were positive for L. monocytogenes, and 3% were positive for both bacteria (co-infection). The leukocyte count was higher than the normal range (0 - 1 Mil/mL) in all semen specimens. The prevalence of C. trachomatis in azoospermic patients was significantly higher than that of nonazoospermic (P < 0.05). However, there was no significant difference between the two groups in terms of the detection of L. monocytogenes (P > 0.05). Detection of C. trachomatis and L. monocytogenes had no significant association with abnormal semen parameters in asymptomatic patients (P > 0.05). Conclusions: The results indicated that precise analysis of semen parameters and diagnosis of leukocytospermia in patients using the PCR can be considered as a rapid and accurate technique to detect bacteria such as C. trachomatis and L. monocytogenes in semen specimens. Therefore, the utilization of this technique in the screening programs for asymptomatic infertile couples can be helpful for early treatment.

Background review for the '2015 European guideline on the management of Chlamydia trachomatis infections'

SummaryChlamydia trachomatis infections are major public health concerns globally. Of particular grave concern is that the majority of persons with anogenital Chlamydia trachomatis infections are asymptomatic and accordingly not aware of their infection, and this silent infection can subsequently result in severe reproductive tract complications and sequelae. The current review paper provides all background, evidence base and discussions for the 2015 European guideline on the management of Chlamydia trachomatis infections (Lanjouw E, et al. Int J STD AIDS 2015). Comprehensive information and recommendations are included regarding the diagnosis, treatment and prevention of anogenital, pharyngeal and conjunctival Chlamydia trachomatis infections in European countries. However, Chlamydia trachomatis also causes the eye infection trachoma, which is not a sexually transmitted infection. The 2015 European Chlamydia trachomatis guideline provides up-to-date guidance regarding broader indications for testing and treatment of Chlamydia trachomatis infections; clearer recommendation of using validated nucleic acid amplification tests only for diagnosis; advice on (repeated) Chlamydia trachomatis testing; recommendation of increased testing to reduce the incidence of pelvic inflammatory disease and prevent exposure to infection and recommendations to identify, verify and report Chlamydia trachomatis variants. Improvement of access to testing, test performance, diagnostics, antimicrobial treatment and follow-up of Chlamydia trachomatis patients are crucial to control its spread.

2015 European guideline on the management of Chlamydia trachomatis infections

Chlamydia trachomatis infections, which most frequently are asymptomatic, are major public health concerns globally. The 2015 European C. trachomatis guideline provides: up-to-date guidance regarding broader indications for testing and treatment of C. trachomatis infections; a clearer recommendation of using exclusively-validated nucleic acid amplification tests for diagnosis; advice on (repeated) C. trachomatis testing; the recommendation of increased testing to reduce the incidence of pelvic inflammatory disease and prevent exposure to infection; and recommendations to identify, verify and report C. trachomatis variants. Improvement of access to testing, test performance, diagnostics, antimicrobial treatment and follow-up of C. trachomatis patients are crucial to control its spread. For detailed background, evidence base and discussions, see the background review for the present 2015 European guideline on the management of Chlamydia trachomatis infections (Lanjouw E, et al.
