TRUJILLO, Esperanza et al. Genotype distribution of Human Papillomavirus in women from Bogotá with abnormal cervical smear. rev.colomb.cancerol. [online]. 2016, vol.20, n.1, pp.3-9. ISSN 0123-9015.  https://doi.org/10.1016/j.rccan.2015.11.003.

Objective: To determine the distribution of HPV genotypes in women from Bogotá with abnormal cervical smear. Methods: Cervical samples were collected from 191 women with ASCUS, 236 with low-grade (LSIL) and 116 with high-grade squamous intraepithelial lesions (HSIL). HPV typing was performed using consensus PCR primers GP5+/GP6 + and reverse line blot. Results: The prevalence of HPV was 76.1%. Unique infections were observed in 41.4% of the participants and co-infections in 34.6%. The frequency of HPV according to diagnosis was: 60.2%, 84.7% and 84.5% in ASCUS, LSIL and HSIL respectively. HPV16 and 58 were the more frequent types in the three groups, HPV16 frequencies were 20.4%, 33.9% and 38.8%, and HPV58 frequencies were 7.3%, 13.6%, and 18,1% for ASCUS, LSIL and HSIL respectively. The third type in frequency in ASCUS and LSIL was HPV56 (6.8% and 11.0%), while in HSIL was HPV18 (10.3%). Infections with probably oncogenic types or with low risk types were much less frequent and generally were observed as co-infections with high-risk types. Conclusions: Infections with high risk HPV types were the most frequent in all studied lesions, VPH-58 ranked second in frequency as has been reported in Mexico and in general in South America. The change to new prophylactic vaccines including more viral types as HPV58 could have a higher impact in reducing the incidence of pre-neoplastic lesions in our region.
