Human papillomavirus genotypes in women with cervical cytological abnormalities from an area with high incidence of cervical cancer ; Genotipos de virus papiloma humano en mujeres con alteraciones citológicas cervicales de un área con alta incidencia de cáncer cervical

It has been well demonstrated the relationship between the infection with high-risk human papillomavirus (HPVs) genotypes and cervical cancer. In Northeastern Argentina a high incidence of this pathology has been described and therefore a high prevalence of HPV infection is expected. In order to identify HPV genotypes associated with malignant and pre-malignant cervical lesions present in the area, 53 ecto-endo cervical cell specimens obtained from women with cytohistological alterations were studied by a PCR-RFLP technique. Out of 53 patients, 34 (64.2%) were positive for HPV infection, being HPV-16 (32.3%) the most frequently found genotype, followed by HPV-58 (14.7%), -6, -18 and –45 (5.9%), -33, -52, -53, -54, -56, -66, -MM4 and –LVX100 (2.9%). Also 5 cases of infection caused by multiple genotypes were found, which corresponded to 14.7% of the positive cases. Results indicate that besides HPV-16 and –18, the most prevalent high-risk HPV genotypes worldwide, others like –45 and –58 as well as co-infection cases are frequent between women of Northeastern Argentina, and a particular attention should be paid to this circumstance because it could be an epidemiological feature of regional importance and a useful information for a future vaccination program. ; La relación entre la infección por los virus papiloma humanos (HPVs) de alto riesgo y el cáncer de cuello de útero ha sido bien demostrada. En el Nordeste de Argentina se observa una alta incidencia de esta patología y en consecuencia se estima una alta prevalencia de infección por HPV. A fin de identificar los genotipos de HPV presentes en el área, asociados a casos de lesiones malignas y premalignas de cuello de útero, se estudiaron 53 muestras ecto-endo cervicales de mujeres con alteraciones citohistológicas residentes permanentes de las ciudades de Resistencia y Corrientes. De las 53 pacientes estudiadas, 34 resultaron positivas para HPV (64.2%), correspondiendo la mayor frecuencia a HPV-16 (32.3%), seguido por HPV-58 (14.7%), HPV-6, -18 y –45 (5.9%), ...
