The aim of the study was to evaluate the frequency of occurrence of Chlamydia trachomatis (C.t.) DNA in the prostate material in the group of individuals with the chronic prostatitis.
The study included 65 males aged between 47 and 68 years of age, reporting for transrectal prostate biopsy because of the elevated serum prostate-specific antigen concentration and/or abnormalities detected in prostate palpation per rectum. The urethral smear collection was performed in all the patients in order to detect C.t. DNA. After that, the transrectal prostate biopsy was performed (histopathology tests, C.t. DNA). Additionally, the levels of anti-C.t. IgG antibodies and anti-C.t. IgA antibodies were checked in the serum. The DNA isolation from prostate specimens was conducted with the use of the Chelex method, while the C.t. DNA detection - with the ligase chain reaction. Specific antibodies were detected with the use of the ELISA method.
C.t. DNA in the prostate gland was found in 7 out of 65 men (10.8%). In urethral smear, C.t. was found in none of the individuals. Anti-C.t. IgA antibodies were detected in the serum of 16/65 (24.6%), while anti-C.t. IgG antibodies in 6/65 (9.2%) of the examined males. IgA antibodies were found in two and IgG in one out of the 7 men who had C.t. infection in the prostate.
The presence of C.t. DNA in the prostate gland may be indicative of the role of chlamydia in the development of chronic prostatitis.
本研究的目的是评估慢性前列腺炎患者前列腺组织中沙眼衣原体(C.t.)DNA的出现频率。
本研究纳入了65名年龄在47至68岁之间的男性,这些男性因血清前列腺特异性抗原浓度升高和/或直肠指检发现异常而接受经直肠前列腺活检。对所有患者进行尿道涂片采集以检测C.t. DNA。之后,进行经直肠前列腺活检(组织病理学检查、C.t. DNA检测)。此外,检测血清中抗C.t. IgG抗体和抗C.t. IgA抗体的水平。使用Chelex方法从前列腺标本中分离DNA,而使用连接酶链反应检测C.t. DNA。使用ELISA方法检测特异性抗体。
65名男性中有7名(10.8%)在前列腺中发现了C.t. DNA。在尿道涂片中,未在任何个体中发现C.t.。在16/65(24.6%)的受检男性血清中检测到抗C.t. IgA抗体,而在6/65(9.2%)的受检男性血清中检测到抗C.t. IgG抗体。在前列腺中有C.t.感染的7名男性中,有2名发现了IgA抗体,1名发现了IgG抗体。
前列腺中存在C.t. DNA可能表明衣原体在慢性前列腺炎的发生发展中起作用。
