a b s t r a c t CONTEXT:In spite of the wide-ranging literature on the microbiology of normal and abnormal flora of the vagina, there are few studies on the relationship between human papilloma virus (HPV) and other vaginal microorganisms. OBJECTIVE:To analyze the frequency of infection by human papilloma virus (HPV) and other agents like Candida sp., Gardnerella vaginalis and Trichomonas vaginalis in cytological smears. DESIGN STUDY: Retrospective study SETTING:A public tertiary referral center. SAMPLE:An analysis of 17,391 cytologies from outpatients seen between January 1997 and August 1998. The control group was made up of patients in the same age group and same period with no cytological evidence of HPV infection. Patients with a diagnosis of cervical intraepithelial neoplasia (CIN) II or III were excluded from this analysis. MAIN MEASUREMENTS:The diagnosis of HPV infection was made in accordance with the criteria of Schneider et al. and the diagnosis of Gardnerella vaginalis was made with a finding of clue cells.RESULTS: 390 (2.24%) had alterations consistent with infection by HPV, sometimes associated with CIN I. The results showed that Gardnerella vaginalis was the most frequent agent in women with HPV infection (23.6% versus 17.4%; P <0.05), while in the control group the most frequent agent was Candida sp. (23.9% versus 13.8%; p <0.001). CONCLUSION:In spite of this study being based solely on cytological criteria, in which specific HPV and Gardnerella diagnostic tests were not used, the cytological smear is widely used in clinical practice and the data presented in this investigation show that there is an association between Gardnerella vaginalis and HPV infection. It remains to be established whether the microorganisms favor each other.

The aim of this study was to verify the presence of bacterial vaginosis (BV), Candida sp, Chlamydia trachomatis, Neisseria gonorrhoeae, to determine the prevalence of tobacco use and measure vaginal pH (VpH) in pregnant women with (n = 26) and without (n = 26) human papillomavirus (HPV) infection, and make comparisons between these 2 groups. HPV, C. trachomatis and N. gonorrhoeae were diagnosed using hybrid capture, BV using clinical criteria, and Candida sp via cultures. A digital pH meter was used to measure VpH. The frequencies of Candida sp were 19.2 and 23.1% (p = 1), and VpH was 4.4 ± 0.4 and 4.3 ± 0.4 (p = 0.23), in the HPV-positive and HPV-negative groups, respectively. Compared to the group of pregnant women without HPV infection, those with HPV infection had a significantly higher prevalence of tobacco use (50 vs. 11.5%; p = 0.006), BV (53.8 vs. 15.4%; p = 0.007), and C. trachomatis (34.6 vs. 7.7%; p = 0.039). No case of N. gonorrhoeae was diagnosed. All cases of C. trachomatis and BV had high-grade HPV infection.

We conducted a retrospective study on 201 conizations for CIN III done over the last 14 years. Of these, 53 (26.4%) had involvement of the margins, 114 (56.7%) had margins free of neoplasia, and 34 (16.9%) were not evaluated. Of the 53 cases with margin involvement, 28 (52.8%) had complementary surgery and 25 (47.2%) cytological follow-up. Residual CIN was identified in the surgical specimen in 15 cases (53.6%) and microinvasion was present in 2 cases (7.1%). Of the 114 patients with margins free of neoplasia in the cone, 12 had a hysterectomy during follow-up for CIN III diagnosed by cytology and biopsy. Seven of these 12 patients (58.3%) had CIN in the surgical specimen and none had microinvasive cancer.

Independentemente da faixa etária, fatores relacionados à maior freqüência de infecção pelo HPV, como a gravidez, hábito de fumar, método anticoncepcional e infecções genitais, têm sido estudados. Alguns autores demonstraram maior incidência de infecção por HPV em gestantes, sugerindo ser a gestação um fator de risco independente para infecção por HPV [3][4][5] . No entanto, outros autores descrevem incidência igual ou menor em mulheres gestantes em relação às não-gestantes [6][7][8] . Em relação aos métodos contraceptivos, o uso de anticoncepcional oral (ACO) parece ser um fator de risco isolado para aumentar a incidência de infecção por HPV. Este aumento é explicado por alterações hormonais que levariam a imunomodulação 9 com maior susceptibilidade à
