ABSTRACT

A infecção do papilomavírus humano (HPV) é uma das mais freqüentes doenças sexualmente transmissíveis em todo o mundo. A relação entre o HPV genital e oral permanece incerta, assim como o seu papel na carcinogênese oral. O objetivo deste estudo foi verificar a presença do DNA do HPV na mucosa oral e genital de mulheres com infecção genital por HPV, pela técnica de reação em cadeia de polimerase (PCR). FORMA DE ESTUDO: Coorte transversal. MATERIAL E MÉTODO: Trata-se de um estudo piloto, prospectivo, com 30 mulheres, idade de 14 a 51 anos, portadoras de infecção genital por HPV confirmada pelo exame de histopatológico. Todas as pacientes foram submetidas a exame e coleta por raspagem da cavidade oral e genital para pesquisa do DNA do HPV pela técnica PCR. RESULTADOS: Nenhuma das amostras da cavidade oral foi positiva para HPV, enquanto no genital, o HPV foi detectado em 17 (57 por cento) das 30 pacientes, principalmente o HPV 6b e 16. CONCLUSÃO: Os resultados mostraram maior porcentagem do HPV genital em relação à cavidade oral, e sugerem que o HPV genital não parece ser fator predisponente para a infecção oral no mesmo paciente.


Infection by the Human Papilloma Virus (HPV) is one of the most frequent sexually transmitted diseases all over the world. The relationship between oral and genital HPV remains uncertain, as it is with its role on oral carcinogenesis. The goal of the present investigation was to check for the presence of HPV DNA in the oral and genital mucosas of women with HPV genital infection, using the polymerase chain reaction (PCR). STUDY METHOD: Cross-sectional cohort. MATERIALS AND METHODS: this is a pilot and prospective study involving 30 women, aged between 14 and 51 years, with HPV genital infection, confirmed by histopathology. All the patients were submitted to the exam and sample collection by swabbing the oral and genital mucosas in order to test for HPV DNA through the PCR technique. RESULTS: none of the oral cavity samples were positive for HPV, while in the genital tract, HPV was detected in 17 (57 percent) of the 30 patients, especially HPVs 6b and 16. CONCLUSION: Results show a higher percentage of genital HPV in comparison to the oral cavity, and suggest that genital HPV does not seem to be a predisposing factor for the oral infection in the same patient.
