چکیده
OBJECTIVE To determine microbial and behavioural factors contributing to non-gonococcal urethral symptoms in men. METHODS Case-control study of heterosexual men with non-gonococcal urethral symptoms (cases) and without urethral symptoms (controls) attending Melbourne Sexual Health Centre, Australia. Sexual behaviour and condom use were measured by questionnaire. First stream urine was tested for potential pathogens: Chlamydia trachomatis (ligase chain reaction), Mycoplasma genitalium (polymerase chain reaction, PCR), Ureaplasma urealyticum (culture and PCR), and Streptococcus spp, Gardnerella vaginalis, and Haemophilus species (culture). Urethral smears from cases were examined for polymorphonuclear leucocytes. RESULTS 80 cases and 79 controls were recruited over 4 months in 2002-3. 49 cases (61%) had urethritis by microscopic criteria, 17 (21%) had Chlamydia trachomatis (adjusted odds ratio (OR) 27 (95% confidence interval (CI): 3.4 to 222)), five (6%) had Mycoplasma genitalium (OR 6.1 (95% CI: 0.6 to 61)), and 11 (14%) had Gardnerella vaginalis (OR 9.0 (95% CI: 1.6 to 52)). Other organisms were not significantly associated with urethral symptoms. The presence of urethritis on urethral smear did not predict the presence of Chlamydia trachomatis (OR 1.7 (95% CI: 0.5 to 5.4)). Urethral symptoms were significantly associated with unprotected vaginal sex with more than one casual partner (OR 9.3 (95% CI: 1.3 to 65)) and unprotected anal sex with a regular partner in the past month (OR 3.5 (95% CI: 1.0 to 13)). CONCLUSION Gardnerella vaginalis and unprotected anal sex may cause symptoms of non-gonococcal urethritis. Microscopy of the urethral smear to diagnose urethritis in this population does not help to identify which men with urethral symptoms require treatment for chlamydia.

Urethral specimens from 477 men were collected with endourethral swabs and examined for Chlamydia trachomatis by cell culture on McCoy cells pretreated with idoxuridine. Of these men, 141 had gonococcal urethritis, 262 non-gonococcal urethritis (NGU), and 74 showed no evidence of urethritis. Of 118 men with heterosexually acquired gonococcal urethritis, thirty (25 per cent.), and of 23 men with...

OBJECTIVES To identify the proportion of cases of non-gonococcal urethritis (NGU) in which Chlamydia trachomatis was detected in patients and their partners, using DNA amplification testing; and to relate the importance of age and symptoms to the presence of chlamydial infection and so clarify the aetiology and epidemiology of NGU, with a view to reducing the prevalence of chlamydial infection ...

The percentage of gonococcal isolates in King County, Washington, requiring citrulline and uracil (CU auxotype) increased from 1.6% in 1986 to 16.5% in 1997. Among men, urethral infection with the CU auxotype (n=93), in comparison with infection by other auxotypes (n=1211), was associated with coexisting chlamydial infection, younger age, heterosexual contact, and fewer new recent partners (P<....

BACKGROUND/AIM Non-gonococcal urethritis (NGU) is a very common sexually transmitted disease. The etiology of the disease is complex and not completely solved. The aim of this study was to determine the bacteriological finding in the urethra in men with and without non-gonococcal urethritis. METHODS The study group comprised 200 men with symptoms of urethritis. The control group consisted of ...

Men with non-gonococcal urethritis (NGU) were divided into two groups and treated with either lymecycline or tinidazole; anaerobic cultures were performed before and after treatment. Neither treatment affected the anaerobic flora. However, the men treated with lymecycline were relieved of symptoms and signs, while those treated with tinidazole were not. The anaerobic bacteria found are consider...
