To correlate the expression of high-risk HPV E6 mRNA with pap smear, colposcopy, and biopsy results in women with high grade squamous intraepithelial lesion (HSIL).
A cross-sectional study was performed on women referred for primary care services after cytological diagnosis of HSIL. We evaluated the expression of E6/E7 mRNA of HPV types 16,18,31,33, and 45 and correlated the results with those of Pap smear, colposcopy, and biopsy. For amplification/detection of mRNA E6 / E7 we used NucliSENSEasyQ kit to detect HPV mRNA by polymerase chain reaction with primers/ probes for HPV types 16, 18, 31, 33, and 45.
Out of 128 valid tests, the results of 30 (23.4%) tests were negative and 98 (70%) tests were positive. Only one type of HPV was detected in 87.7% of the E6/E7 mRNA positive cases. HPV16 was detected in 61.2% of the cases, followed by HPV33 (26.5%), HPV31 (17.3%), HPV18 (10%), and HPV45 (4.08%). Pap smear tests revealed that the E6/E7 test was positive in 107 (83.8%) women with atypical squamous cells - high grade (ASC-H), HSIL, or higher. The E6/E7 test was positive in 69 (57.5%) specimens presenting negative cytology results. When analyzing the association with colposcopy results, the frequency of positive E6/E7 results increased with the severity of the injury, ranging from 57.1% in women without colposcopy-detected injury to 86.5% in those with higher levels of colposcopy findings. Of the 111 women who underwent biopsy and E6/E7 testing, the E6/E7 test was positive in 84.7% of the women who presented with lesions of cervical intraepithelial neoplasia (CIN) grade 2 or higher. Finally, 41.2% of women with a negative biopsy presented a positive E6/E7 test.
E6/E7mRNA expression was higher in women with HSIL and CIN grade 2 or higher.

PURPOSE: to study the clinical and microbiological profile of women with bacterial vaginosis participating in a randomized, double-blind clinical trial, which compared the vaginal use of preparations from red pepper tree and metronidazole for the treatment of genital discharge. METHODS: the study was conducted on a series of 277 women with bacterial vaginosis concomitantly diagnosed by the criteria of Amsel and Nugent, selected from a total of 462 recruited patients using the information obtained before intervention. Data were analyzed with the Epi-Info 3.32 software. In order to compare the outcomes frequencies between the intervention groups, the χ2 test was used and the risk ratio and 95% confidence interval were calculated. The intention to treat analysis was performed. In addition to the determination of diagnostic parameters, the culture of vaginal content and a Papanicolaou cytology test were also performed. RESULTS: the most frequent clinical complaints were genital discharge, observed in 206 participants (74.4%) and the fish odor of the vaginal secretion, which occurred in 68.6% of the cases (190 patients). Among the diagnostic clinical criteria, the presence of clue-cells was positive in 275 women (99.3%), the Whiff test, in 266 (96.0%), followed by pH >4.5, which occurred in 92.8% of the cases, and by the presence of fluid grayish discharge reported by 206 participants (74.4%). Regarding the Nugent criterion, the median score was 8.0. Culture of the vaginal content permitted the identification of Gardnerella vaginalis in 96.8% of cases and of Mobiluncus in 53.1%. Only one third of the exams showed the presence of Lactobacillus (89 women - 32.1%). Fungal growth occurred in the cultures of 14 participants (5.1%). In most cases, culture revealed the presence of Corynebacterium (94.2%), Gram-positive cocci (98.2%), as well as Gram-positive (99.3%) and Gram-negative (91.0%) bacilli. Oncotic colposcopy revealed a very scarce presence of lactobacilli, which were present in only 8 cytological exams (2.9%) out of the total of 273 exams performed. CONCLUSIONS: the results of the present study did not differ from the literature regarding the symptoms reported by the women, the clinical criteria most frequently observed in the diagnosis, or the bacterial species detected in cultures of vaginal content. These findings indicate the need for further studies that might better elucidate the interrelations between the microbiological findings and the clinical expression of bacterial vaginosis.
