ABSTRACT

Chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. The aim of this study was comparison to evaluate the prevalence of Chlamydia trachomatis infection in woman with tubal infertility by means of PCR and cell culture techniques. Fifty-one women with confirmed TFI were enrolled in this study in [avicenna infertility Clinic] between January 2010 and January 2011. Cervical swab and cytobrush specimens were collected from each patient by gynecologists and sent to laboratory in transport media. Detection of Chlamydia trachomatis in samples was performed using PCR and bacteria culture in MacCoy cell line. The data were analyzed by Fisher's exact test and independent t-test. Statistical significance was established at a p-value <0.05. A significant relation was observed between increased the age of first intercourse and chlamydial infection. Six [11.7%] samples had positive PCR result, whereas cell culture results were positive in only 2 [3.9%] samples. A significant relation was also identified between the duration of infertility and infection [p<0.05] by PCR versus cell culture method. The results showed that PCR is a rapid method, compared to cell culture for detecting Chlamydial organism. It also became clear that the age at first intercourse is important to predict the likelihood of Chlamydia trachomatis

ABSTRACT

Nowadays, Chlamydia trachomatis is known as a causative agent of infertility. Because of, asymptomatic nature of infection, many may suffer from its lasting complications such as infertility. This study was performed in Tehran during April 2007 to April 2008 to compare the prevalence of Chlamydia trachomatis infection in fertile and infertile women using ELISA and PCR methods. Overall, 234 infertile and 223 pregnant women, as the fertile group, participated in this hospital-based case-control study. After completing an informed consent form and the questionnaire, first catch urine and blood sample were obtained for PCR and ELISA [IgG, IgM] tests, respectively. Logistic regression analysis was used to control possible confounding factors, and determine adjusted odds ratio of infertility due to the infection. PCR results revealed that 29 [12.4%] of the infertile and 19 [8.5%] of the fertile women were positive for C. trachomatis infection [p=0.440]. IgG was positive in 21 [9.0%] of the infertile and 11 [5.0%] in the fertile group [p=0.093]. IgM assays identified that 2 [0.9%] of the infertile and 4 [1.8%] of the fertile women were positive for the micro-organism [p=0.375]. We found no significant differences among fertile and infertile women for Chlamydia trachomatis infection. Nevertheless, molecular techniques which are more sensitive, more specific and non-invasive can be used to detect C. trachomatis infection

ABSTRACT

Chlamydia trachomatis is the most common bacterial sexually transmitted infection in the world, but the effect of this infection on male fertility is still controversial. Despite reports of interaction between Mycoplasma genitalium and sperm, this pathogen in semen samples of infertile men is less studied. We studied, the prevalence of Chlamydia trachomatis and Mycoplasma genitalium infection in infertile men. Among attending Avicenna Infertility Center, 120 men who had abnormal semen analysis tests were selected and the samples were taken. After detailed analysis of semen quality, DNA was extracted from each sample by chelex. Samples were evaluated for these two pathogens by multiplex PCR. Results were statistically analyzed. Chlamydia trachomatis and Mycoplasma genitalium was detected in 23/3% and 12/5% of the samples, respectively. Although, Mycoplasma genitalium infection rises by increasing [P=0.640] and decreasing in age of first sexually activity [P=0.203], and also positive cases of Chlamydia trachomatis infection showed increase regarding age increase [P=0.619] and age decrease in first sexually activity [P=0.511], but these differences were not statistically significant. All in all, regarding to the increased prevalence of Chlamydia trachomatis infection compared with the only similar study in Iran and high prevalence of Mycoplasma genitalium infection in infertile men, this assessment was done. A multiplex PCR protocol rapidly and simultaneously identify these organisms in comparison with uniplex from clinical samples. Based on our results screening for Chlamydia trachomatis and Mycoplasma genitalium infection among infertile men seems to be valuable
