To determine the frequency of sexually transmitted infections (STIs) in asymptomatic women and the association of STIs with cervical intraepithelial neoplasia (CIN).
A cross-sectional studywas performed, enrollingwomen examined in a general gynecology clinic and in a colposcopy referral center fromOctober 2014 to October 2015. The colposcopy groupconsisted of 71women, and the general gynecologygroupconsisted of 55 women. Cervical samples were collected for cervical cytology and a multiplex realtime polymerase chain reaction (PCR) was developed to detect human papillomavirus (HPV) and the STIs caused by the following microorganisms: Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Neisseria gonorrhoeae. A multivariate analysis was performed by logistic regression, considering the significance level of 0.05.
The general frequency of STIs was: 46.8% (HPV); 27.8% (C. trachomatis); 28.6% (M. genitalium); 0.8% (M. hominis); 4.8% (U. urealyticum); and 4.8% (N. gonorrhoeae). The significant risk factors for CIN were: HPV infection (odds ratio [OR] = 2.53; p = 0.024); C. trachomatis (OR = 3.04; p = 0.009); M. genitalium (OR = 2.37; p = 0.04); and HPV and C. trachomatis coinfection (OR = 3.11; p = 0.023). After the multivariate analysis, a significant associationwas found betweenHPVand CIN(OR = 2.48; 95% confidence interval [95%CI]: 1.04-5.92; p = 0.04); and between C. trachomatis and CIN (OR = 2.69; 95%CI: 1.11-6.53; p = 0.028).
The frequency of STIs was high in asymptomatic patients. Infections by HPV and C. trachomatis were independently associated with the presence of CIN. The high frequency of STIs in asymptomatic women suggests the need for routine screening of these infections.

PURPOSE: to determine the prevalence of Chlamydia and gonorrhea in a sample of women from Curitiba. METHODS: this was a cross-sectional study with a sample of sexually active non-pregnant women aged between 16 and 23 years-old, with an intact uterus, with up to four sexual partners, without evidence of fever or purulent cervicitis, submitted to pelvic examination and PCR-based urine- testing for Chlamydia and gonorrhea. Exclusion criteria included: vaccination for HPV, vaccination history for the past 21 days, previous abnormal cytology, history of genital warts, splenectomy, immune disorders, and use of immunosuppressive drugs. An interview regarding sociodemographic and obstetric data and gynecological risk behavior for sexual transmitted diseases was applied. For statistical analysis, we used the c2 or Fisher’s exact test to assess the association between variables. RESULTS: the prevalence of Chlamydia and gonorrhea infection in the study group was 10.7 and 1.5%, respectively, and the rate of coinfection was 0.9%. No correlation was found between the age range of the volunteers, the onset of sexual activity, the number of sexual partners and of new sexual partners in the last six months, and the presence of Chlamydia or gonorrhea. In women who had vaginal discharge or ectropion, the prevalence of Chlamydia infection was two times higher than in those without such signs. CONCLUSIONS: the results of this study were similar to national studies using PCR in urine samples for the detection of Chlamydia and gonorrhea in samples of non-pregnant women of the same age groups and with the same background. Since the volunteers with more than four sexual partners and those who had purulent endocervicitis were excluded, it is believed that the prevalence of Chlamydia and gonorrhea infection could have been greater in this population.
