The vagina and the cervix are the first immune and physical line of defense against sexually transmitted pathogens. However infectious process in the vagina, caused by potentially pathogenic microorganism such as bacterial vaginosis (BV), are very often. This may be associated with a morbid entity as Human Papillomavirus (HPV). It was evaluated the association between the presence of BV and HPV in the lower female genital tract, identifying the clinical and lab aspects in women who received medical attention at emergency rooms in the city of Goiânia-GO and observed the production of cytokines in endocervical secretions in cases with VB associated with HPV. This study included 173 sexually active women, between 16 and 48 years old, divided into groups: control, with BV and with high and low risk of HPV. A survey was conducted to collect the intrinsic and extrinsic factors associated with the patients. Microbial cultures, vaginal pH, identification of high and low risk of HPV by PCR, and the concentration of cytokines were performed. The result of the research data was submitted to a statistical analysis, calculating the oods ratio, confidence intervals and p of 0,05. Forty seven cases of BV were diagnosed. Besides, the presence of a vaginal pH > 4.5, showed a result statistically significant for the presence of HPV, p = 0.001 was also observed. When analyzing the multivariate logistic regression, the independent risk factors for the presence of VB were: having more than one sexual partner in the last 5 years p<0,001 and have more than 3 sexual intercourses per week p=0,002. But in HPV infection the independent risk factors were: being married p=0,029 and pH &#8804; 4.5 p<0,001 and in the case of high-risk HPV the only independent factor considered was the pH &#8804; 4.5 p= 0,006. Relating HPV infections with high and low risk and the presence of VB with some immune factors by the strength of local cytokines, it was found that, IL-2 and IL-12 were significantly elevated in cases of BV and HPV. The IL-6 was high only for HPV, followed by IFN-gamma and IL-10 although the last two showed a trend towards statistical significance in HPV cases. It was concluded through the univariate analysis that the factors, having more than one sexual partner in the last 5 years, a failure in the use of condoms and the presence of leucorrhoea and dyspaurenia were related to the presence of BV and level of alkaline in the vagina which could possibly predispose to infections HPV, and the immune response Th1-type cytokines in vaginal secretions in the presence of BV and/or HPV may also be similar.
