Detección de VPH en boca y cérvix de pacientes con diagnóstico citológico sugestivo de infección genital / HPV detection in the mouth and cervix of patients with histological diagnosis suggestive of genital infection

En este trabajo se evaluó la presencia de VPH en la cavidad bucal (mediante oroscopia y citología oralexfoliativa) y su relación con la infección genital en mujeres con diagnóstico citológico sugestivo de infección por VPH. La muestra consistió en 60 pacientes a quienes se les realizó oroscopia, citología y determinación viral en boca y cérvix por PCR, utilizando los iniciadores genéricos MY09/MY11 y MPCR. Se detectó ADN de VPH en las mucosas oral y genital en 48,33 % y 73,3% de las pacientes, respectivamente, obteniéndose una concordancia de 44,2% (k=0,44 indicando grado de acuerdo moderado). Los tipos virales más frecuentes fueron de bajo riesgo, especialmente el tipo 6, encontrado en 86,2% de las muestras bucales y 65,9% de las muestras cervicales, solo o en combinación con otros tipos debajo (11) o de alto riesgo oncogénico (16, 18, 33), con una concordancia de 10,45% (k=0,1 indicando grado de acuerdo muy bajo); sin embargo, particularmente en relación al tipo 6, hubo una concordancia de 75,86% (k=0,7 indicando grado de acuerdo alto). La citología de la cavidad bucal tuvo una sensibilidad de 3,5 % y especificidad de 93,6 %. Para la oroscopia, la sensibilidad fue de 27,6 % y la especificidad de 74,2 %. Los resultados señalan que la infección por VPH en cavidad bucal de pacientes con infección genital pudiera ser frecuente. La baja concordancia global entre los tipos virales sugiere que la infección por VPH en boca y cérvix presenta un comportamiento biológico diferente(AU)

This work evaluated HPV infection in the oral cavity (using oroscopy and exfoliative oral cytology) and its relation to genital infection in women with cytological diagnosis suggestive of HPV infection. The sample consisted of 60 patients who underwent oroscopy, cytology and viral determination in mouth and cervix by PCR using generic primers MY09/MY11 and MPCR. HPV DNA was detected in oral and genital mucosa in 48.33% and73.3% of patients, respectively, yielding a concordance of 44.2% (k=0.44, moderate agreement). The most common viral types were low risk, especially type 6,found in 86.2% of oral samples and 65.9% of cervical specimens, alone or in combination with other types of low (11) or high oncogenic risk (16, 18, 33), with a concordance of 10.45% (k = 0.1, insignificant agreement). However, in relation to type 6, there was a concordance of 75.86% (k=0.7, high agreement). The cytology of the oral cavity had a sensitivity of 3.5% and a specificity of93.6%. For oroscopy, sensitivity was 27.6% and specificity was 74.2%. The results indicate that HPV infection in the oral cavity of patients with genital infection could be frequent. The low concordance between HPV types suggests that HPV infection in the mouth and cervix has a different biological behavior(AU)
