Urethritis due to Chlamydia trachomatis.

Abstract

Ninety-five men suffering from gonococcal urethritis were treated and observed. Forty-nine developed postgonococcal non-specific urethritis (PGU). Seventeen men were demonstrated to be free from PGU after careful observation; these formed a control group. Chlamydia trachomatis was isolated from urethral material from 26 (53%) of the PGU group but from none of the controls. This difference was highly significant (P less than 0-001). It confirms that C. tachomatis is a pathogen in the urethra. The presence of specific IgM antibody to C. trachomatis in serum from some men developing PGU, from whom that organism was isolated, suggests that the infection was recent in those cases. Ureaplasma urealyticum (T strain mycoplasma) was isolated from urethral material taken from 22 (45%) of the 49 men in the PGU group, and from 12 (71%) of the 17 in the control group. Mycoplasma hominis was isolated from 10 (20%) of the 49 men in the PGU group, and from four (24%) of the 17 men in the control group. Thus, no evidence was obtained that mycoplasmas (U. urealyticum, M. hominis) are patogenic in the urethra.

Development of a novel quantitative real-time assay using duplex scorpion primer for detection of Chlamydia trachomatis.

A novel quantitative real-time PCR method using the duplex scorpion primer for detection of Chlamydia trachomatis DNA was developed and validated. The assay employs a duplex primer; its most important feature is the intramolecular probe-target interaction. The assay had many prominent characteristics. (i) The duplex probe is simpler to synthesize and significantly easier to purify than TaqMan probe because that the fluorescent dye pair and the quencher pair are in different oligonucleotides. (ii) The method has high sensitivity, specificity, intra- and interassay reproducibilities. (iii) The assay has a quantitative dynamic range of 25 to10(9) genome copies per reaction mixture. (iv) The scorpion system can identify 98.6% samples in the validation panel without retest. There were 81 positive samples and 67 negative samples, which were confirmed by two FDA-approved NAATs (the Roche Amplicor PCR assay, Abbott LCR kit) and our new method. Any two positive results out of the possible three-comparator results would define the infected-patient gold standard. Of the positive samples, 79 (97.5%) were found positive (ranging from 31 to 227,648 copies/microl, M=4219 copies/microl), whereas no negative samples were found positive by the assay. A quantitative, fast, and easy-to-handle diagnostic approach such as the MOMP-based real-time PCR described here might improve the detection of C. trachomatis infection.

[Epidemiology of chlamydial infections].

Genital chlamydia infections are the most frequently diagnosed bacterial sexually transmitted infection (STI) worldwide. Infections with chlamydia trachomatis are not notifiable in Germany. Since 2002, a STI sentinel surveillance including 243 sentinel sites has been set up in Germany. Between January 2003 and June 2006, 6.7% of 46,168 chlamydia tests were positive. Of the 1547 positive patients, 64.3% were women and the median age was 26 years. In this group, 60.4% of women and 29.3% of men were of non-German origin. Heterosexual contacts were stated as the possible source of infection for 42.9% of men and 26.4% of women. A total of 16.1% men and 38.6% women reportedly "always" used condoms with others than their permanent partner. The awareness of chlamydia infections needs to be improved among physicians, patients and the general population.

[Urogenital chlamydial infections in women and men].

Genital infections with Chlamydia trachomatis occur in all social groups in Germany. About 100,000 German women are sterile because of tubal scarring due to chlamydiae. Genital chlamydial infections are asymptomatic in 70% of patients, even if salpingitis occurs. Typical symptoms of chlamydial infection are purulent cervicitis with vaginal discharge, painful cervical bleeding because of endometritis, lower abdominal pain with dyspareunia, and upper abdominal pain because of perihepatitis. DNA amplification tests on first voided urine or cervical swab are the most sensitive routine tests. Specific serum antibodies to C. trachomatis indicate a previous infection in sterile women. For treatment, a 10-14 day course of doxycycline 200 mg daily or a macrolide antibiotic in the patient as well as in the sexual partner is recommended. In the male, C. trachomatis causes urethritis and epididymitis. Opinions differ about involvement of the prostate gland and seminal vesicles. Identification of C. trachomatis antigen or DNA in the accessory gland secretions is not sufficiently reproducible. The two vectors are easily diagnosed in urethral swabs or in urine. The occurrence of chlamydial antibodies in serum or in seminal fluid is not a sign of current infection. Reliable studies which indicate a reduced fertility of men infected with C. trachomatis are not available.
