Chlamydia trachomatis and Mycoplasma genitalium infections are the most prevalent sexually transmitted bacterial infections in the world that cause urogenital infections in both men and women. It appears that infertility is a complication of these infections.
This study was designed to estimate the prevalence of Chlamydia trachomatis and Mycoplasma genitalium in symptomatic and asymptomatic men and to assess risk factors associated with infection.
Urine specimens were collected from 200 men; 100 of them were symptomatic and 100 asymptomatic. Samples were examined by PCR to detect the infections.
C. trachomatis was detected in 20% of symptomatic and in 4% of asymptomatic men (P < 0.001). The prevalence of M. genitalium was revealed to be 12% and 2% in symptomatic and asymptomatic men, respectively (P < 0.01). Four of 100 men in the symptomatic group were infected with both organisms. C. trachomatis infection was associated with dysuria, urethral discharge, testicular swelling, and genital ulcer (P < 0.05). M. genitalium infection was related with dysuria, testis inflammation, pelvic pain and low educational level (P < 0.05). Furthermore, the prevalence of infections at ages 30-39 years was more than other ages.
Considering the role of these bacteria in urogenital infections, a screening test is recommended. Since the PCR assay is a highly sensitive and specific assay for the detection of these bacteria in male urine specimens, it provides a noninvasive technique for routine screening.
沙眼衣原体和生殖支原体感染是世界上最常见的性传播细菌感染,可导致男性和女性的泌尿生殖系统感染。不孕症似乎是这些感染的一种并发症。
本研究旨在估计有症状和无症状男性中沙眼衣原体和生殖支原体的患病率,并评估与感染相关的危险因素。
收集了200名男性的尿液标本;其中100名有症状,100名无症状。通过聚合酶链反应(PCR)检测样本中的感染情况。
有症状男性中20%检测出沙眼衣原体,无症状男性中4%检测出沙眼衣原体(P<0.001)。生殖支原体在有症状和无症状男性中的患病率分别为12%和2%(P<0.01)。有症状组的100名男性中有4人同时感染了这两种病原体。沙眼衣原体感染与排尿困难、尿道分泌物、睾丸肿胀和生殖器溃疡有关(P<0.05)。生殖支原体感染与排尿困难、睾丸炎、盆腔疼痛和低教育水平有关(P<0.05)。此外,30-39岁年龄段的感染患病率高于其他年龄段。
鉴于这些细菌在泌尿生殖系统感染中的作用,建议进行筛查检测。由于PCR检测法在检测男性尿液标本中的这些细菌时具有高度敏感性和特异性,它为常规筛查提供了一种非侵入性技术。
