RESUMO
Resumen Introducción: La infección por VPH es la infección viral de transmisión sexual más frecuente, y se encuentra asociada a diversas neoplasias. Objetivo: Describir la epidemiología, historia natural y factores de riesgo asociados a la infección oral por VPH en adultos jóvenes asintomáticos. Métodos: Se realizó un estudio prospectivo de corte longitudinal, que incluyó sujetos sin patología oral, a los que se les tomó una muestra de la mucosa bucal. A todos los sujetos con resultados positivos se les realizó un nuevo muestreo seis meses después. Se identificó la presencia del virus por RPC; los datos demográficos y de conducta sexual fueron obtenidos con una encuesta que respondieron sin intervención del investigador. Resultados: Se recolectaron 102 muestras de sujetos de 18-26 años de edad, 60 (58,8%) correspondieron al sexo masculino. La prevalencia del virus fue de 6,9%; todos los sujetos positivos tenían vida sexual. Las relaciones sexuales entre personas del mismo sexo fue la única variable asociada a la presencia del virus (p < 0,05). A los seis meses, todos los sujetos habían eliminado al virus. Conclusión: La infección oral por VPH es transitoria y está asociada a relaciones sexuales entre personas del mismo sexo, principalmente mujeres que tienen sexo con mujeres.
Background: HPV infection is the most common sexually transmitted viral infection, and is associated with several neoplasms. Aim: To describe the epidemiology, natural history and risk factors associated with oral HPV infection in asymptomatic young adults. Methods: A prospective and longitudinal study was conducted, including subjects without oral pathology, who were sampled from the oral mucosa. All subjects with positive results were re-sampled 6 months later. The presence of HPV was identified by PCR. Demographic and sexual behavior data were obtained with a survey that was responded without the intervention of the researcher. Results: 102 samples were collected from subject of 18-26 years old, 60 (58.8%) were male. The prevalence of the virus was 6.9%; all positive subjects had active sexual life. Same-gender relationships were the only variable associated with the presence of the virus (p < 0.05). At six months all subjects had eliminated the virus. Conclusion: Oral HPV infection is transient and is associated to same-gender relationships, mainly women who have sex with women.
