Diagnosing Chlamydia Trachomatis Urinary Tract Infections--Preliminary Report.

BACKGROUND Chlamydia trachomatis is mentioned among the etiologic factors for urinary tract infections. Chlamydias are parasites inside a cell. A very significant problem of C. trachomatis infections is their asymptomatic character. The most frequent infections caused by these bacteria are inflammations of the urethra and bladder; of the vagina, cervix, vaginal cavity and adnexa in women; and of the epididymis, testicles and prostate in men. In the diagnosis of C. trachomatis infections, the following methods are used: immunofluorescent techniques, immunoenzymatic assays, serological examinations and genetic techniques (for example PCR). OBJECTIVES The aim of the study was to detect C. trachomatis among patients with symptoms of non-gonorrheal urethritis using diagnostic serologic methods and direct immunofluorescence. The purpose was to assess the connection between the incidence of urinary tract infections caused by C. trachomatis and symptoms that patients report as well as other data from interviews. MATERIAL AND METHODS Blood serum and urethral smears were taken from each of 57 patients. The ELISA method was used to mark specific IgG and IgGcHSP60 anti-chlamydia antibodies in the blood serum. In the urethral smear, antigens were marked using the direct immunofluorescence method. RESULTS Evidence for urinary tract infection caused by C. trachomatis was found in 15.79% of the examined patients using the immunofluorescence method. In the blood serum, positive results for IgGcHSP60 were obtained in 17.54% of the patients and for IgG in 8.77%. CONCLUSIONS The studies carried out so far suggest that C. trachomatis has a significant role in the etiology of urethritis in adults and children. Other serological tests should be conducted in all the patients in order to study the immune responses in infected individuals and to confirm C. trachomatis infection using genetic methods such as PCR.
