- ItemAcesso aberto (Open Access)High Risk HPV E6/E7 Oncoprotein Expression in Women with High Grade Squamous Intraepithelial Lesion(Federacao Brasileira Soc Ginecologia & Obstetricia-Febrasgo, 2016) Cordeiro Valenca, Jefferson Elias; Goncalves, Ana Katherine; Cotrim Guerreiro da Silva, Ismael Dale [UNIFESP]; Eleuterio Junior, Jose; da Silva, Terezinha Tenerio; Bruneska, Danyelly; de Alencar Ximenes, Ricardo ArraesPurpose 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). Methods 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. Results 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. Conclusions E6/E7 mRNA expression was higher in women with HSIL and CIN grade 2 or higher.
- ItemAcesso aberto (Open Access)Importance of peniscopy, oncologic cytology and histopathology in the diagnosis of penile infection by human papillomavirus(Associação Paulista de Medicina - APM, 1997-02-01) Nicolau, Sergio Mancini [UNIFESP]; Martins, Nelson Valente [UNIFESP]; Ferraz, Paulo Eduardo [UNIFESP]; Stávale, João Norberto [UNIFESP]; Goncalves, Wagner Jose [UNIFESP]; Baracat, Edmund Chada [UNIFESP]; Lima, Geraldo Rodrigues de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)INTRODUCTION: Male genital infection by human papillomavirus is of particular importance since it is often asymptomatic. The patient generally presents no clinical lesion. Therefore, men represent an important reservoir of virus, playing a special role in the transmission and perpetuation of the disease. PATIENTS AND METHODS: In the present prospective clinical trial study, 190 sex partners of women with genital infection by human papillomavirus, associated or not with cervical intraepithelial neoplasia, were investigated. All patients were unaware of or denied the presence of a genital lesion. RESULTS: Cytologic examination revealed koilocytosis in 9 cases (4.7%) in the urethra and in 3 cases (1.6%) in the corona of the glans and the distal prepuce. Peniscopy with the previous use of 5% acetic acid revealed white lesions in 97.9% of the patients. Toluidine blue stained most of the lesions. At least one fragment revealed koilocytosis in the histopathologic study of 97 cases (51.05%). CONCLUSION: The three methods complement one another, allowing a more precise diagnosis of this infection in men.
