Prevalence of Sexually Transmitted Infections (Neisseria gonorrhoeae,Chlamydia trachomatis,Trichomonasvaginalisand Human Papillomavirus) in Female Attendees of aSexually Transmitted Diseases Clinic in Ulaanbaatar, Mongolia

[摘要] Background:Epidemiological data suggest that the prevalence of syphilis, gonorrhea and trichomoniasis hasincreased in both urban and rural areas of Mongolia. These data are primarily substantiated by notifications of casesof clinically apparent disease in both rural and urban areas, plus laboratory diagnoses from the AIDS/STD ReferenceCenter,Ulaanbaatar. In the past 5 years, however, there has been a marked decline in the total number of patientsbeing screened for sexually transmitted infections (STIs). An assessment of true prevalence of STIs in a femalepopulation attending an urban sexually transmitted diseases (STD) clinic was therefore commenced.Methods:Consecutivewomen attending an STD clinic in Ulaanbaatar had genital samples collected by the insertionand immediate removal of a tampon, which was then tested for the presence ofNeisseria gonorrhoeae,Chlamydia trachomatis, human papillomavirus (HPV) andTrichomonas vaginalis, using polymerase chain reaction(PCR) amplification.Results:A total of 110 women were studied (mean age 26.7 years). Overall, 58 (53%) patients had one or morepathogens identified; 43 (39%) had a single pathogen, while 15 (14%) had mixed pathogens.C. trachomatiswasfound in 15 (14%),N. gonorrhoeaein 12 (11%),T. vaginalisin nine (8%) and HPV in 39 (36%). Among the 39HPV-positive patients, oncogenic genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52) were found in 17 (44%) patients.Conclusions:Sexually transmitted infections as defined by PCR were common, and found in 53%of femaleattendees of an urban STD clinic in Mongolia. As infections with conventional STIs increase the risk of humanimmunodeficiency virus (HIV) transmission, it is imperative that strategies be introduced to reduce the prevalenceof STIs. Furthermore, detection of oncogenic HPV was common, indicating that it is vital that a strategy to reducecervical cancer such as a pre-cancer cervical cytology screening program also be introduced.
