Detection of Trichomonas vaginalis and its Relationship to Vaginal Microorganisms and Sex Hormones

The study was conducted between August 2014 and the end of February 2015. It is included the collection of 227 blood samples and vaginal swabs for women suffering from itching, irritation and vaginal discharge, whom consulted the private outpatient clinics, the infertility units and the consulting clinic of Al-Batoul Teaching Hospital for Maternity and Children. Blood samples were taken to the laboratory to measure sex hormones levels. The vaginal swabs were sent to the microbiology unit for the purpose of examining the vagina pH and conducting a wet swab or microscopic examination for each sample and then vaginal swabs were cultured on both the parasite medium (CPLM) and the appropriate media to investigate the presence of bacteria. The results showed the vaginal infections at pH> 4.5 was higher than the infections value at pH ≤4.5. The outcome of the study indicated to presence of (25.9%) of cases (59 patients) was infected by Trichomonas vaginalis. The highest incidence of trichomoniasis with Gardnerella vaginalis was detected in 22 cases (37.2%). The lowest infections value was associated with Neisseria gonorrhoeae, which was detected in only one case (1.6%). On the other hand, there was a relationship between the level of sex hormones and Trichomonas vaginalis. The results appeared that the levels of trichomoniasis increased when the rate of estradiol decreased. While infection rates increased when progesterone levels increased in the follicular phase and decreased in the luteal phase. In addition testosterone increased in women with trichomoniasis, in comparison with the control group.
